Resynchronizing databases

CAUTION

Resynchronizing databases is a lengthy process.

Allow 1-2 hours to complete the operation.

Only trained personnel should perform the following task.

In the unlikely event that changes to the primary database are not propagated to the secondary database, the two databases must be manually resynchronized as follows:

In a telnet window

1Login to the primary database as oracle.

2Do the following:

cd /IMS/imssipdb/data/db_schema resync_rep_db.sh

Note: This command removes all application-related information from the secondary database and then resynchronizes the secondary database with the data from the primary database.

Disk space management

Oracle uses indexes to quickly access frequently used data. However, when records in a table are deleted, the associated indexes for the deleted records are nulled, but not deleted.

Over time, the indexes of frequently added and deleted tables increase in size, even though the number of records in the table stays relatively the same. Periodic optimization improves index lookup time and reduces disk usage.

The following procedure drops and recreates all the indexes in a database. It also deallocates any unused space in a tablespace, thus optimizing the space usage.
