Application Tier Size
Oracle E-Business Suite Release 12.2 introduces Online Patching. This requires three application tier file systems:
•
fs1 (Production file system) – Used by the current users of the system.
•
•
•
fs2 (Copy of production file system) – Used by the patching tools.
fs_ne (Non-editioned file system) – Stores files containing data that is needed across all file systems (for
example, data import and export files, report output files, and log files).
Inst (INST_TOP) - Oracle E-Business Suite Release 12 Instance Home, contains all the config files, log files, SSL
certificates etc.
All three file systems serve a single database. The file system that is currently being used by the running application is
never patched: all patches are applied to the file system that is not currently in use.

Release 12.2 Upgrade Best Practices
Recommended initialization (init.ora) parameter settings for the upgrade.
•
It is recommended to follow AWR pool advisories for optimizing the SGA and PGA size in the Release 12.2
upgrade.
•
An upgrade involves tens of concurrent sessions. Suitable starting values are:
1. log buffer = 30 to 100 Mb
2. shared pool = 1 to 4 GB
3. pga target = 3 to 20 GB
4. buffer cache = 5-50 GB (multi-GB)
•
You should ensure that SGA and PGA are allocated appropriately within the available memory of the
system. If set higher it may cause excessive paging, or even swapping.
•
Set “job_queue_processes = No. of CPUs” – adobjcmp.sql (Phases: plb+90 and last+63)
This parameter is set at the beginning of the upgrade; it will be most useful in the phases mentioned
above.
•
Setting parallel_max_servers to 2 x no. of CPUs will help with large index creation, statistics gathering, and
some large upg+ phase jobs.
•
In order to maximize multiblock I/O sizes, you should remove "db_file_multiblock_read_count" (if
specified).
•
Ensure you reset the following init.ora parameters after completion of the Release 12.2 upgrade.
o recyclebin
o parallel_max_servers
o job_queue_processes
Isolate post-upgrade concurrent programs to a separate manager queue.
The downtime portion of the upgrade involves the automatic submission of 95 distinct concurrent programs. For a list of
the programs, refer to the "Required Post-Upgrade Jobs" section of this document.
In several cases, these programs will run in multiple threads, so the total number of concurrent requests that form part
of the post-upgrade step is much higher. These programs will be picked up and executed by the concurrent manager
once the system is up, and as such their execution will be mixed with the execution of ongoing concurrent jobs in the
system.
To improve manageability of this situation, you can define a separate concurrent manager queue to process only these
programs. This can be achieved by using inclusion and exclusion rules to prevent other manager queues (such as the
standard manager) from picking up these requests, and cause this new manager queue to only process these requests.
Doing this allows you to control the number of target processes allocated to these post-upgrade concurrent programs,
including dynamically with the use of work shifts. For additional details about configuring new manager queues, target
processes, inclusion/exclusion rules, and work shifts, refer to Oracle E-Business Suite Setup Guide from the Onine
Documentation Library.
Before you shut down all services as part of the “Perform the Upgrade“ tasks mentioned in the Upgrade Guide, you
need to deactivate all Request Processing managers. This is needed so that when the services are brought up at the end
of the upgrade, the existing Request Processing Managers do not start picking up and executing requests. After the
upgrade is complete, you need to perform the following steps to create new program type and managers to run the
post-upgrade requests.
To create a new program type, and include a program in that program type:
1. Log in to Oracle E-Business Suite as SYSADMIN, and navigate to System Administrator > Concurrent : Program >
Type
Name: R12PUPT
Application: System Administration
Description: Program Type for Post Upgrade Request
2. Include programs from the above list into this new program type.
3. Navigate to System Administrator >Concurrent: Program >Define
4. Search for Program "Refresh Materialized Views"Type (choose):R12PUPT
5. Do the same for other programs in the list.
To exclude a program type from the Standard Manager:
1. Log in to Oracle E-Business Suite as SYSADMIN and navigate to System Administrator > Concurrent : Manager
>Def ine
2. Search for Standard Manager.
3. Click on Specialization Rules.
4. Go at the bottom of the list to add a new record.
5. Include/Exclude (choose): Exclude
Type(choose): Request Type
Application(choose): System Administration
Name(choose): R12PUPT
6. Do the same for all other Request Processing managers.
To create a new concurrent manager and include a program type:
1. Log in to Oracle E-Business Suite as SYSADMIN and navigate to System Administrator > Concurrent: Manager >
Define
2. Check the Enabled box.
3. Enter the following to create the new concurrent manager:
Manager: R12_Post_Upgrade
Short Name: R12PU
Application(choose): Application Object Library
Description: New manager queue for R12 post upgrade requests
Type(choose): Concurrent Manager
Cache Size: 1
Program Library Name(choose): FNDLIBR
Specialization Rules:
Include/Exclude(choose): Include
Type(choose): Request Type
Application(choose): System Administration
Name(choose): R12PUPT
Work Shifts:
Work Shift (choose): Standard
Processes: Enter a Value, for example 4
Sleep Second: 30
After completing the above steps, activate all "Request Processing Managers" that you previously deactivated.
Note that after all these post-upgrade requests run, you should revert the exclusion/inclusion of managers and
programs to the original state, removing the new program type and new manager. This is necessary as some of the
programs in the list may need to run in the future, as part of the regular system batch processing requirements rather
than part of the upgrade.
Determine optimal number of workers for upgrade.
While monitoring CPU usage and I/O response times, you should test a range of values between 1 x No. of CPUs to 1.5 x
No. of CPUs, . The goal is to maximize the number of workers, while keeping CPU usage below 100% (ignoring occasional
spikes) and I/O response times below 10-15 milliseconds (again, ignoring occasional spikes).
Required Post-Upgrade Jobs
Below is a list of of the concurrent programs that form part of the required post-upgrade steps. These concurrent
programs are automatically submitted during the regular downtime upgrade, so no manual submission is required.
These jobs took 7 hours for the 456 GB database upgrade, using 30 target processes in the concurrent manager.

Sample Upgrade Timings
Before applying the main 12.2 upgrade driver (u10124646.drv), AD patch 10117518 must be applied on both file systems
(fs1 and fs2). As a result of applying this patch, two new schemas (APPS_NE and GHG) will be created for use in Release
12.2.
The overall time taken to apply the patch was about two hours.
1. Time taken for creating the users and granting privileges to them was 20 minutes.
2. Compiling JSPs (using perl) took 1 hour 30 minutes.
3. The following database activity timing information is for the Release 12.2 AD patch (10117518), which took 5.5
minutes.

The upgrade is a very I/O intensive process, moving, updating, and indexing large amounts of data. As such, I/O
subsystem performance and bandwidth are critical to minimizing the amount of downtime. During many Release 11i to
Release 12 customer upgrades, poor I/O sub-system performance was found to be one of the major sources of upgrade
performance service requests.
Therefore, during the upgrade testing process you should monitor I/O performance and correct any issues found. As a
reference, shown below are the IOPS rates and bandwidth measurements that were obtained while testing the upgrade
with the 456 GB database. The numbers were calculated based on data from AWR and OS monitoring utilities.
IOPS:
•
•
•
Maximum IOPS value is 478.9.
During upgrade, IOPS range is from 142 to 478.9. Max value is reported during large indexes creation phase.
High IOPS value (140 to 478) is seen during UPG phases.
I/O Read bandwidth:
• Maximum I/O Read bandwidth (in MB): 10.23
• During upgrade I/O Reads ( in MB) per second range is from 1.44 to 10.23
• Max value is reported during dat and upg phase.
I/O Write bandwidth:
• Maximum I/O Write bandwidth (in MB): 3.09
•
•
During upgrade I/O Writes per second range is from 0.9 to 3.09 MB.
Max value is reported during dat phase.
I/O Response Times ( in milliseconds):
• Below 20ms for the vast majority of AWR snapshot periods. Higher values were present with spikes above 50ms
during the Large indexes create phase and some upgrade phases.
Timing information for Release 12.2 Edition-Based Redefinition (EBR) enablement (Patch 13543062)
Timing reported here is only for application of the EBR enablement patch. Apart from patch application, many other
steps are performed in enabling EBR. The time these take will depend upon the customizations you have.
Refer the the following document for the steps needed to enable EBR:
• Oracle E-Business Suite Upgrade Guide Release 12.0 and 12.1 to 12.2, Part No. E48839 (Section 4, Oracle EBusiness Suite Online Patching)
You need to register all your custom schemas, following the procedures in the above document.
