Database Maintenance Window
Schedule a maintenance window of two to four hours weekly during off peak hours of operation to
do the following database maintenance operation:
1. Stop the service for the management server. See ”Restarting the Service for the Management
Server” on page 16.
2. Access the Database Admin Utility. See ”Accessing the Database Admin Utility” on page 233
for more information.
3. Using the Database Admin Utility, verify that the database is in an open state and the listener is
running. See ”Checking the Database and Listener Status” on page 234.
If the database state is not OPEN and shows an error, get the following logs and then contact
technical support:
• Log file for the Database Admin Utility:
%MGR_DIST%/logs/dbAdmin.log
• Database alert log, which can be found in one of the following locations:
• On Microsoft Windows: \oracle\admin\APPIQ\bdump
• On UNIX systems: $ORACLE_BASE/admin/APPIQ/bdump
4. Reset the temporary tablespace, as described in ”Resetting the Temp and Undo Tablespace” on
page 238.
5. Export the database, as described in ”Exporting the Database” on page 236.
6. If the database is running in archive mode, set the database to no-archive mode, as described in
”Changing the Archive Mode” on page 240. Then, clean the
\oracle\oradata\APPIQ\archive on Microsoft Windows and
$ORACLE_HOME/oradata/APPIQ/archive on UNIX systems.
