How to reinitialize the embedded SOLID DB
It is always a good idea to stop all NNM processes before recreating a new embedded
database, but it is not mandatory.
The procedure to reinitialize the DB consists of 4 major steps:
- stop the current instance of Solid embedded DB (if still running)
- remove the current DB files
- create an empty DB
- create the tables.
An additional step (d) needs to be performed if the ovdw.conf file is lost or corrupt. The
ovdwcfggetset utility will recreate this file.
It is important to understand that all 3 DWH and SOLID ini files contain the correct
information about data source and accessibility of the data source.

Procedure:
a) stop the current instance (if NNM processes are still
running)
ovdbcheck -stop
b) remove the current DB files
UNIX: cd $OV_DB/analysis/default
rm solid.db
rm solmsg.*
rm ./log/sol*.log
NT: cd \Openview\databases\analysis\default
del solid.db
del solmsg.out
del log\sol?????.log # new location for the Solid DB log
files
del sol?????.log
# old location for the Solid DB log
files
del solerror.out
c) create a new DB
ovdbrun will create an empty database in the current
working directory. Change to:
UNIX: cd $OV_DB/analysis/default
NT: cd \OpenView\databases\analysis\default
ovdbrun -x exit -u ovdb -p ovdb
d) additional step to re-create the ovdw.conf file,
change to:
UNIX: cd $OV_CONF/analysis
$OV_BIN/ovdwcfggetset -file ovdw.conf -s : -set "user:
ovdb"
$OV_BIN/ovdwcfggetset -file ovdw.conf -s : -set "password:
ovdb" -encrypt 1
$OV_BIN/ovdwcfggetset -file ovdw.conf -s ": @" -set
"dbname: UPipe NNM"
$OV_BIN/ovdwcfggetset -file ovdw.conf -s ": @" -set "db:
yes"
NT: cd \OpenView\conf\analysis
\OpenView\bin\ovdwcfggetset.exe
"user: ovdb"
\OpenView\bin\ovdwcfggetset.exe
"password: ovdb" -encrypt 1
\OpenView\bin\ovdwcfggetset.exe
set "dbname: ovdbrun"
\OpenView\bin\ovdwcfggetset.exe
set "db: yes"
-file ovdw.conf -s : -set
-file ovdw.conf -s : -set
-file ovdw.conf -s ": @" -file ovdw.conf -s ": @" -
Note: the data source for the UNIX product(s) is "UPipe
NNM", for NT "ovdbrun"
e) start the instance and create the new table structure
you need to change the current working directory to:
UNIX: cd $OV_CONF/analysis/sqlScripts
NT: cd \Openview\conf\analysis\sqlScripts
ovdbcheck -start
ovdwquery -file tables_common.solid
ovdwquery -file tables_event.solid
ovdwquery -file tables_trend.solid
ovdwquery -file tables_topo.solid
f) shut down the new instance and start it using ovstart
ovdbcheck -stop
ovstart -v ovdbcheck
Note: meaning of the DWH and SOLID config files:
SOLID DB config file, used to set some DB
solid.ini
defaults as well as what type and how many
listener are started when the SOLID DB engines
tarts up.
NNM Data Ware House config file, used by ovdw*
utilities to read the name of the data source
ovdw.conf
and also holds password information. It also
tells if the DB needs to be started at access
time if it down.
UNIX only:
System ODBC config file, used by ovdw*
system_odbc.i utilities (and others) to know how and where to
ni
contact the a specific data source.
Use the Control Panel, ODBC32 Driver settings
to make any changes to the ODBC Driver to
NT only:
access the Solid instance. The System DSN name
ODBC32
and Network Name (ovdbrun by default) has to
Settings
match the name configured in the ovdw.ini and
solid.ini files.
Note: This procedure will not restore a lost solid.lic file (Solid DB license file). If the
user did a backup using ovbackup.ovpl, then you can copy the solid.lic file from the
backup directory, else you have to copy it from the CDRom.
Backup directories for Solid internal backup is:
UNIX: $OV_DB/analysis/default/backup
NT: \OpenView\databases\default\backup
