AIX Server 2: IBM RS6000 – 6F1

Processor: 4 – way CPUs 600 MHz each

Memory: 8 G

Disks: two 36G disks Raid 1 for applications

Ten (10) 72G disks total size 350G RAID 10 for data

Comparing Database System:

Database system:

Microsoft SQL Server 2000 with SP 3

Microsoft Windows XP Professional Workstation

Processor: Pentium III 996 MHz

Memory: 512 M

Disk: One internal IDE disk size 37.2 G

About the system of this tuning project:

The databases I use for this tuning project is PeopleSoft ERP application for Finance and Human

Resource Management. Oracle database engine is used as backend database server.

On the above Server list, AIX Server 1 is our production server. AIX Server 2 is Disaster

Recovery Server.

Because PeopleSoft ERP system is a mature application, we just need a few coding for customize the modules. Almost all problem queries are generated by “Query Builder” for Ad Hoc reports.

Our users do not know how to coding SQL.

PeopleSoft Application supports multi-database servers: Oracle, IBM DB2, SQL Server,

Informix…… PeoperSoft builds the database structure as portable as he can! There are not

3

primary key and foreign key for data integration, PeopleSoft use its application to control the data integration. There more than 7,000 tables, 3,000 indexes and 2,000 views in Finance database. There are more than 5,000 tables, 3,000 indexes and 2,000 indexes in HRMS database.

For security reason, views are used for different user groups. Most of those views are built on views too (depth to several levels). If we just simply re-write the problem queries using the base tables of views, user cannot submit it through their GUI application interface. Anyway I still have to do what I can do under those restrictions.

Case 1: Reduce the size of large update transactions (Ref. Chapter 2.3.2)

Scenario: We have a table named PS_HR_ACCTG_LINE which storages the data of payroll. There are

200,000 to 300,000 rows added each month after payroll run. We need purge those data once a while.

Problem: When our HRMS manager tried to purge data, he used query builder GUI to generate the DDL

Statement:

DELETE FROM PS_HR_ACCTG_LINE A

WHERE A.JOURNAL_DATA < TO_DATE(‘2005-07-01’,’YYYY-MM-DD’);

He hits the error “rollback tablespace runs out of space” all the time.

Indexes on the Table:

There are two indexes have been built on this table:

1.

Unique index PS_HR_ACCTG_LINE on columns RUN_DT, SEQNUM and LINE_NBR;

2.

Unique index PSAHR_ACCTG_LINE on columns ACCTOUNT, PROGRAM_CODE,

DEPTID AND PROJECT_ID

Analysis: Since I know that the size of our rollback tablespace is 3 times of the size of table

PS_HR_ACCTG_LINE, we cannot just enlarge rollback tablespace for this issue.

Accord to professor’s book, I decide to try two methods:

1.

Reduce the size of this transaction: the data type of column JOURNAL_DATE is date.

We can reduce the range of date and cut the big batch to several same batch transactions.

2.

There is no index on column JOURNAL_DATE. This update process leaded a full table access on table PS_HR_ACCTG_LINE. I tried to create an index on column

JOURNAL_DATE, and compare the response time. (index vs. update)

Result:

Method 1:

When I delete the data from PS_HR_ACCTG_LINE based on every two months, the response time was 35min58sec. 497,282 rows deleted. This is not an acceptable response time.

Then I reduce the update on one month each time. The response time was 3min9sec and

217,814 rows deleted. This is an acceptable response time.

Figure case 1.1 Reduce the size of large update transactions. Compare the batch size of

497282 rows and 271047 rows (which is an average of 10 small batch processes), we can see that throughput got extremely improved (5 times).

Method 2:

The original execute plan of this delete statement is:

393426 rows deleted.

We can see there is a full table access on the table PS_HR_ACCTG_LINE. Our update statement bases on a column with type date. I created an index on this column to see if it can improve the response time.

After I created the index, the SQL explain plan was as the following:

Index created.

Our database’s optimizer mode is CHOOSE, which means Oracle will calculate the cost of processing. Even we created an index on column JOURNAL_DATE, it looks like that

Oracle did not use the index. But statistics are little different. We can see that there is

4.23 seconds’ improvement between two elapsed times before/after index created.

Compares the statistics, we also can see that “recursive calls, db block gets, redo size etc.” are increased a lot. It is not worth to use those system resources to trade 4.23 seconds response time. [Dennis: Also the delete would update the index all the time.]

Testing run on Microsoft SQL Server:

About the SQL Server environment

Since the hardware of my Dell workstation is not very good, I did not convert my whole ERP database to SQL Server from Oracle database Server. I just copied all tables for all queries which each case needs here from Oracle to SQL server. I also created same indexes, views as we have in Oracle Database. Even though, size of SQL testing database is over 4 G.

I could not convert data type BLOB column from Oracle to SQL Server. I removed those columns from those tables with data type “LONG” before I copied them to SQL Server.

Anyway, my case study doesn’t need those columns.

8

The queries I ran on two database are little different too. Some single row functions which

Oracle SQLPLUS supports are not supported by SQL Server Transact-SQL. I modified those codes of views, queries to make them executable on SQL Server.

That means, the result my testing got from Oracle and SQL Server, could not be compare between database levels. It only can be use to compare before or after tuning in same database engine.

Result:

Number of deleted rows

393,426

609,212

I was very surprised when I got the result.

Response time

47 sec

33 sec

First of all, I found that the batch size has no affect to the response time. Actually, the larger batch update transaction has bigger throughput than the small one.

Second, for a single DDL event, the response time of SQL Server is excellent: [Dennis:

Interesting.]

SQL Server. Compare the batch size of 393426 rows on Oracle Database Engine and MS

SQL Server engine, we can see that throughput of SQL Server is almost 7 time more than

Oracle.

transaction on SQL Server. Compare the batch size of 393426 rows and 609212 rows on

MS SQL Server. We can see that throughput of large update transaction is also bigger. If

I have more time for study, I may study what the main factors are which affect the response time between the batch size on different database engines.

Why SQL Server runs DELETE statement is more effectible than Oracle?

I found that I cannot rollback the deleted rows on SQL Server. On the SQL Server on-line book, under the topic “You are about to delete a row or rows” it says:

“Choosing yes will delete the selected row from the table. If you say Yes, the deletion will be immediatedly transmitted to the database. You will not be able to undo this change.”

I realized that SQL Server only writes redo logs. Oracle writes redo logs and undo(rollback segements). [Dennis: Does this version of sql server have multiversion read consistency?]

Then I did a test of SELECT statement:

On Oracle: select * from PS_HR_ACCTG_LINE where JOURNAL_DATE < ’01-OCT-05’;

393426 rows selected.

Elapsed: 00:11:32.58

On SQL SERVER: select * from PS_HR_ACCTG_LINE where JOURNAL_DATE < ’2005-10-01

00:00:00.000’;

Process dead after 34 min running due to memory leak.

I also check the update/insert statement. SQL Server cannot rollback the action of executing an

UPDATE/INSERT too. SQL Server is an auto-commit database system. [Dennis: Perhaps you need to begin and end transaction]

Summery:

On Oracle database:

1.

Reduce the size of large update transactions can extremely reduce response time and improve the throughput.

2.

When we run update statement, it need bigger redo size. The redo size is not calculated by the size of affected data.

On MS SQL Server database:

3.

The size of batch update transactions does not affect the response time and throughput.

It because that SQL Server is an auto commit database system, it executes DDL statements (insert/update/delete) without undo information. All executed DDL action cannot be undo.

Conclusion:

Reduce the size of large update transactions will help response time and throughput a lot on non-auto-commit database system (such as Oracle – write undo and redo), but not on autocommit database system (such as SQL Server - write redo only; IBM DB2 – write redo only;

Sybase, Informix and MySQL).

11

***************************

An Extra Test on SQL Server:

I discussed with some DBA friends about auto-commit database system and response time of update transactions. They told me that I can turn off auto-commit on one particle transaction on those database systems.

Such as on DB2, add the option parameter “+c” before update transaction command to turn off auto-commit; and on SQL Server, auto commit also can be turned off.

I tested the response time after I turned off auto commit of SQL Server. I found that autocommit on/off doesn’t affect the response time – SQL Server still writes redo log only.

Set implicit_transaction on

Begin tran delete from ps_hr_acctg_line where journal_date < '2005-09-01 00:00:00.000'



Rollback time: 16 seconds delete from ps_hr_acctg_line where journal_date < '2005-10-01 00:00:00.000'



Rollback time: 1 min 33 seconds

83120 rows

393426 rows

0 delete rollback

Figure case 1.3 Througput (rows/sec) of a small update transaction and a big update

transaction on SQL Server after auto-commit turned off. Compare the batch size of 83120 rows and 393426 rows. After auto commit was turned off, the throughput of DETELE doesn’t affect (33 sec. on 393426 rows with auto-commit on, yesterday). The throughput of rollback process of big batch transaction and small batch transaction are similar. We know that the

SQL Server is a database only write redo.

I think that relation between execution time and batch size depends on database structure which means the database engine is writing undo only or writing undo AND redo.

12

Case 2: Minimizing DISTINCTs (Ref. Chapter 4.6.1)

Scenario: Our users use query builder to generate SQL code for their report. They really don’t know how database engine runs SQL. Sometime their queries do not return any result after a few hours running. I helped them to tuning a lot of those problem queries. I found the users add

“DISTINCT” to guarantee their queries return unique records all the time, but most of time

“DISTINCT” caused the performance problems and those “DISTINCTs” do not needed on the query at all.

Problem: I received this problem query on October 3 right after I read section 4.6.1 of professor’s tuning book. I cannot to wait to use the skill I learned from book to tuning the following query:

SELECT DISTINCT B.NAME, A.EMPLID, A.EMPL_RCD, TO_CHAR(A.EFFDT,'YYYY-MM-DD'),

A.EMPL_STATUS

FROM PS_JOB A, PS_B_FAST_EMP_QRY A1, PS_PERSONAL_DTA_VW B, PS_B_FAST_PERS_QRY B1

WHERE A.EMPLID = A1.EMPLID

AND A.EMPL_RCD = A1.EMPL_RCD

AND A1.ROWSECCLASS = 'CPHR7030'

AND B.EMPLID = B1.EMPLID

AND B1.ROWSECCLASS = 'CPHR7030'

AND ( A.EFFDT =

(SELECT MAX(A_ED.EFFDT) FROM PS_JOB A_ED

WHERE A.EMPLID = A_ED.EMPLID

AND A.EMPL_RCD = A_ED.EMPL_RCD

AND A_ED.EFFDT <= SYSDATE)

AND A.EFFSEQ =

(SELECT MAX(A_ES.EFFSEQ) FROM PS_JOB A_ES

WHERE A.EMPLID = A_ES.EMPLID

AND A.EMPL_RCD = A_ES.EMPL_RCD

AND A.EFFDT = A_ES.EFFDT)

AND A.EMPLID = B.EMPLID ) ;

He had been waiting more than 5 hours and got no any date returned! He asked me to kill his session which was processing the query and help tuning it.

Description of the involved tables and views in this query:

There are 5 tables and 5 views involved in this query.

Tables:

Like I mentioned above, PS doesn’t use primary key. Here I consider NO NULL with Unique index columns as Key.

***********on FROM clause

 PS_JOB, a big table with 217 columns and 87,857 rows

Key: emplid, emp_rcd, effdt and effseq.

***********not on FROM clause

 PS_PERSON, 10 columns and 13,268 rows

Key: emplid

 PS_FAST_SCRTY_2, 4 columns and 14,970 rows

Key: setid, deptid and rowsecclass

 PS_NAMES, 23 columns and 15,179 rows

Key: emplid, name_type and effdt

13

 PS_PERS_DATA_EFFDIT, 75 columns and 13,441 rows

Key: emplid, effdt

Views:


 PS_B_FAST_EMP_QRY is a view, built on 3 base tables and 1 view

Tables: PS_JOB, PS_PERSON AND PS_FAST_SCRTY_2

View: PS_PERSON_NAME

 PS_PERSONAL_DTA_VW, built on 1 view

View: PS_PERSONAL_NAME

 PS_B_FAST_PERS_QRY, built on 2 base tables and 1 view

Tables: PS_JOB and PS_FAST_SCRTY_2 view: PS_PERSONAL_DT_FST


 PS_PERSONAL_NAME

Table: PS_NAME

 PS_PERSONAL_DT_FST

Table: PS_NAME

Analysis:

On the Section 4.6.1 of Professor’s tuning book, Professor says:

Generalizing from this example, we conclude that if the fields returned constitute a key of one table T and all other tables perform an equijoin with T by their keys, then the values returned will contain no duplicates, so DISTINCT will be unnecessary.

I will say this skill is the most helpful skill for my environment. I have known that 80% of our problem queries caused by “SELECT DISTINCT”, but I don’t know how to get rid of it. I always joke with my co-workers that “select distinct “ is my nightmare! This tuning skill really helps me get rid of 50% of our problem queries. I used to re-rewrite those problems queries before.

Let’s go back to check the example problem query.

There are 4 objects on FROM CLAUSE. PS_JOB is a table with key. The other 3 objects are views.

We have to find out the columns work as key for the result of those views first.

PS_B_FAST_EMP-QRY: base on 3 tables and 1 view, PS_PERSON_NAME

PS_PERSONAL_DTA-VW: base on view PS_PERSON_NAME

PS_B_FAST_QRY: base on two tables and 1 view: PS_PERSONAL_DT_FST

So, I have to check view PS_PERSON_NAME and PS_FERSONAL_DT_FST first.

** Please find the detail DDL of those views on Appendix. [Dennis: ok]

View PS_PERSON_NAME

Built on table PS_NAMES, key columns of the table: emplid, name_type, effdt

Column emplid – means employee id. It is unique and not null for any employee. On PS_NAME table, one EMPLID may come with different NAME_TYPE and Effdt. View PS_PERSON_NAME returns the NAME_TYPE = ‘PRI’ and max(EFFDT) for each EMPLID.

EMPLID acts like the key of view PS_PERSON_NAME

View PS_ERSONAL_DT_FST

Built on table PS_NAME, PS_PERSON (key: emplid) and PS_PERS_DATA_EFFDT (key: emplid, effdt). View returns PS_PERSON.EMPLID (key of PS_PERSON);

On the where clause:

Table PS_PERS_DATA_EFFDT join with PS_PERSON, with EMPLID and max(effdt) of a range date –- which return unique result;

And

Table PS_NAME, restricted NAME_TYPE = ‘PRI’ and max(EFFDT) of a range date, with

EMPLID column, EMPLID also can act as the key now, and join with EMPLID of PS_PERSON.

Now, we can say that EMPLID acts like the key of view PS_PERSONAL_DT_FST too.

PS_B_FAST_EMP_QRY

Built on table PS_JOB (key: emplid, emp_rcd, effdt and effseq), table PS_FAST_SCRTY_2 (key: setid, deptid, rowsecclass); Table PS_PERSPN (key: emplid), and view PS_PERSONAL_DT_FST.

On where clause of this view, join condition does not cover all key columns of all involved tables and view. It returns a cartesian production of (EMPLID, EMP_RCD) x ROWSECCLASS

The key of view would be (EMPLID, EMP_RCD), ROWSECCLASS

PS_PERSONAL_DTA_VW

Built on view PS_PERSON_NAME, and EMPLID is also acts as the key of result

PS_B_FAST_PERS_QRY

Built on Tables PS_JOB and PS_FAST_SCRTY_2; and view PS_PERSONAL_DT_FST

On where clause of this view, join condition does not cover all key columns of all involved tables and view. It returns a cartesian production of EMPLID x ROWSECCLASS

The key of view would be EMPLID , ROWSECCLASS

Now, (after a coffee break, of course) I can start to analyze the problem query now.

On the SELECT clause, the selected columns do not cover all key columns of table PS_JOB.

Column EFFSEQ missed. But on the WHERE clause:

AND A.EFFSEQ =





Guaranteed that selected key columns of table PS_JOB return unique result from PS_JOB;

16

Result:

PS_FAST_EMP_QRY, because of line AND A1.ROWSECCLASS = 'CPHR7030' , EMPLID becomes a key and join with PS_JOB;

PS_B_FAST_PERS_QRY, because of line AND A1.ROWSECCLASS = 'CPHR7030' , EMPLID becomes a key and join with PS_PERSONAL_DTA_VW;

PS_ERSONAL_DATA_VW, joins with PS_JOB on its key column EMPLID.

We can say it now, The SELECT statement can return the same result without DISTINCT.

With DISTINCT:

User ran over 5 hours without any data returned. User session was killed by DBA.

I also re-ran the same query over 3 hours without any data returned.

After DISTINCT removed:

1 min 34.94 seconds! [Dennis: Wow, that’s awesome!]

DISTINCT without DISTINCT

Fetch 20283 rows on MS SQL Server

Figure case 2.1 Throughput (rows/sec) of a query with “SELECT DISTINCT/SELECT”.

Compare the batch size of 20283 rows FETCHED with/without “DISTINCT”. After I removed “distinct” the query throughput is improved 15.88 times.

Conclusion:

Minimizing DISTINCT in the query can improves the performance and reduces the response time.

Case 3: Query Tuning (Ref. Chapter 4.6)

Scenario:

Our Peoplesoft HRMS programmer showed me the following query, and told me it never return any data to her after 30 minutes. She said, she did not miss any join condition; all join were on key column of tables; and it was just a very simple query. She did not understand what the problems were.

(Cost=2 Card=15182)

The optimized Mode we use is CHOOSE. Oracle calculates the cost of this query is 693 .

On the class of AQuery, I got some a hint when professor talked about “Cost based

Optimization” and “Interchange sorting + order preserving operators”. The hint is left all group by, sorting etc. below the bottom of each join.

Then I re-wrote the query. Actually what I did was only re-organized the order of WHERE clauses as following:

SELECT a.emplid

FROM ps_job a,


ps_jobcode_tbl b,

ps_personal_data c,

ps_sal_grade_tbl d,

ps_employment e

WHERE a1.emplid = a.emplid

AND a1.empl_rcd = a.empl_rcd

AND 'PPALL' = a1.rowsecclass

AND a1.emplid = e.emplid

AND a1.empl_rcd = e.empl_rcd

AND b.setid = a.setid_jobcode

AND a.jobcode = b.jobcode

AND c.emplid = a.emplid

AND d.setid = a.setid_salary

25

AND d.sal_admin_plan = a.sal_admin_plan

AND d.grade = a.grade

AND e.emplid = a.emplid

AND e.empl_rcd = a.empl_rcd

AND c.emplid = a1.emplid

AND e.emplid = c.emplid



WHERE b_ed.setid = b.setid

AND b_ed.jobcode = b.jobcode

AND a.effdt >= b_ed.effdt)



WHERE d_ed.setid = d.setid

AND d_ed.sal_admin_plan = d.sal_admin_plan

AND d_ed.grade = d.grade

AND d_ed.effdt <= SYSDATE)

AND a.effdt =(SELECT max(a_ed.effdt)

FROM ps_job a_ed

WHERE a_ed.emplid = a1.emplid

AND a_ed.empl_rcd = a.empl_rcd

AND a_ed.effdt <= SYSDATE)


FROM ps_job a_es

WHERE a_es.emplid = a1.emplid

AND a_es.empl_rcd = a.empl_rcd

AND a_es.effdt = a.effdt);

Oracle SQL Server

Figure case 3.1 Throughput (rows/sec) of a query with before/after re-write. Compare the batch size of 20283 rows FETCHED with/without “DISTINCT”. After I removed “distinct” the query throughput is improved 15.88 times.

Conclusion:

Optimizer of database system is not as smart as we think  .

When Tuning a SQL,

1.

Minimized the data as much as possible before submit it to upper level join.

2.

We need care about the join condition of WHERE clause. I used to think that cost base database system is smart enough to detail with nature join - I did not realize that the order of enjoin conditions affects query assess plan. [Dennis: Right. When it gets complicated]

Case 4: Understanding Access Plan (Ref. Appendix D)

Scenario: I tuned a query for one of our developer against our testing environment (added an index to one of the tables). It works fine on our testing environment – execution time is 52.73 seconds

(before I tuned the query, it did not return any data after 2 hours).

On the next coming morning, our program told me, the query did not work on our production system.

Analysis:

The above is query is one of our problem queries, which I cannot remove “distinct”. Table

PS_PAY _CALENDAR missed join with other tables.

30

At the beginning, I thought it is impossible that same query works on testing system, but does not work on production system. Our testing database was cloned from production couple of weeks ago. I spent a couple of hours to compare the two environments. I did not find any different.

It is weird! Does production system uses same explain plan to process the query as testing system?

The cost of testing system is 340; the cost of product system is 353 – The explain plans are different between testing and production. But it looks like no big different. But what caused the different process steps? Testing system and production database have same parameters, same database structure (tables, indexes - all system analyzed recently). The only different is the data – after we cloned the testing system from Production system, there is no any update on testing system any more.

Thought I don’t think the minor different between the data size of production system and testing system, I have to admit that Oracle calculates the query cost base on the table size.

I tried to force the query use RULE BASE to run on the production system – it works now.

Optimized Mode

On the APPENDIX D of professor tuning book, it talks about the Access Plan of IBM DB2 database system. I think that the access plan of all RDBMS system has similar concept.

From this case, I learned:

1.

Don’t trust Oracle CHOOSE optimized mode.

2.

I don’t know how many percent is – size of data the query needs access - when Oracle calculates the expense of explain. It maybe very a very important part.

3.

If optimized mode “CHOOSE” works, do not force query running by RULE base. (To compare the response time of RULE base between production system and testing system – testing system has less data, the response time is 5 times than production system. On the testing, response time of RULE base is 1.5 time of CHOOSE mode.

4.

[Dennis: I didn’t quite understand this case study though I found it interesting that using

Rule was helpful. My guess is that Rule is helpful when the query gets complex enough. It would be interesting to put exactly the same data on the test system and try it again.]

37

Case 5: Troubleshooting (Ref. Chapter 7)

Chapter 7 teaches us the skills how to troubleshooting. My experience is, if you know your system well, it is very easy to catch the problem.

Like our system – PeopleSoft ERP system. PeopleSoft said, their application has been well tuned.

It is correct. We seldom received problem on application side. I may catch dead lock error once or twice a year – we cannot re-product the error.

We have 4 – ways CPUs. If we have 2 or 3 processes using 25% CPU each (such as the queries above), our system would be slow, and all users’ processes hang.

Unix utility “topas” can help us to find out which process cause the problem.

I use the following steps to catch the bad query in our system:

Step 1,

Use UNIX utility:

User: root

Command:

****** topas –i 5

On this screen print, we can find out:

CPU useage

Disk I/O

Memory usage

Paging status

We also can catch top processes.

38

Step 2,

If I found a top process of user

“oracle” from above screen, I would write down of PID of that process.

Then, I use “Oracle

Enterprise Manager console” to catch database session. The top PID is showed under

“OS Process ID” column.

Step 3,

Just double click the problem session, we can see the detail session information:

General information

SQL text/explain plan

Statistics

Locks

If it is a problem query, I can catch the

SQL text here, and tuning it.

39

Step 4,

From “General” tab, we can get more information about the session user.

I also can kill user’s session here. Tuning

SQL TEXT, and ask user run it again.

40

Other Tuning Experience

1. Band variables

Application uses band variable when they parse SQL statement to database server. Oracle doesn’t treat band variable and regular variable (which parse from SQLPLUS command line) same. [Dennis: bound not band, I think]

Such as, in the WHERE clause,

Where year = :year

Is not as same as

Such as, in the WHERE clause,

Where year = :year

Is not as same as

Where year = ‘2005’

2. RAID

I remember I tuned one query when I worked for North Shore Hospital. Our developer forwarded me a query which only needed couple of seconds to return the result from SQLPLUS command line. But if filled in Year parameter from application, and parse the same query to oracle, it needed 3 and half hours to return 3 rows.

In This case, we need check query explain plan.

Other problem about band variable is – the length of variable. The length of variable is one factor of Oracle optimizer calculating cost. If the same parameter is parse to Oracle the second time,

Oracle would not re-calculate the cost. Oracle would use the same explain plan as the first time.

It also causes performance problem.

We all know that RAID 5 is good for write, and RAID 10 is good for read. [Dennis: I think just the opposite. I’d use Raid 10 for writes and Raid 5 for reads. Is this a typo?] Actually I did not feel any different during the normal work. In general, we use two RAID controllers on one production server. One is for disks which storages Operation System. Another RAID controller is used for disks of data. If a server needs write log on RAID 5 disks, storages data on RAID 10 disks, it may need 3 RAID controllers. (System Administrator will never like this idea.)

Our production UNIX server was built on RAID 1. This server was purchased before I work for this company. My co-workers told me that the hardware configuration was recommended by

IBM engineer. We got enough headaches on DISK I/O problems and files’ storage. For an example, after I switched some data files between 2 mount points, the running time of one big batch report reduced from 1.5 hour to 15 minutes.

41

When we procedure our DR server last year, I asked our System Administrator configure disks array of data to RAID 10. We get rid of those disk I/O and files storage problem at all.

3. Data Warehouse System:

Disable foreign key during data loading;

Drop all indexes and rebuild them after data loading.

In most of case, foreign key is used to force data integration. When we loading data external data into database, we wish I can load data into database first, kick off the bad data later. If foreign keys exist during data loading, it takes huge time to check data integration plus other relative processes.

I also recommend dropping all indexes before loading data. I used to create two scripts - Run the one which drops all indexes before data loading, and runs other one which re-create all indexes after data loading. [Dennis: And what happened?]

Advanced Database Systems

Report of Tuning Project

[See my comments below beginning with “Dennis:” In general a very nice job though I would have like to hear what happened in your data warehouse experiment]

About the system of this tuning project:

Case 1: Reduce the size of large update transactions (Ref. Chapter 2.3.2)

Throughput between Oracle and SQL

Server

Case 2: Minimizing DISTINCTs (Ref. Chapter 4.6.1)

Generalizing from this example, we conclude that if the fields returned constitute a key of one table T and all other tables perform an equijoin with T by their keys, then the values returned will contain no duplicates, so DISTINCT will be unnecessary.

Case 3: Query Tuning (Ref. Chapter 4.6)

Case 4: Understanding Access Plan (Ref. Appendix D)

Case 5: Troubleshooting (Ref. Chapter 7)

Other Tuning Experience

1. Band variables

2. RAID

3. Data Warehouse System:

Disable foreign key during data loading;

Drop all indexes and rebuild them after data loading.

Appendix: DDL statement of tables and views in case study
