Destroy and Re-Create a New Standby

You can destroy and recreate a new standby by duplicating the new active with the ttRepAdmin -duplicate command.

During these steps, application processing can continue at the active database.

Stop the cache agent on the new standby database:
```
ttAdmin –cacheStop ttdb1
```
As the cache manager user, drop all cache groups using ttIsql:
```
DROP CACHE GROUP t_cg;
```
Destroy the database:
```
ttDestroy ttdb1
```

Re-create the new standby database by duplicating the new active.

ttRepAdmin -duplicate -from ttdb2 -host ttsrv2 –setMasterRepStart -UID 
ttAdmin -PWD ttadminpwd -keepCG -cacheUID cacheadmin -cachePWD cadminpwd ttdb1

Start cache and replication agents on the new standby ttdb1 database:
```
ttAdmin –cacheStart ttdb1
ttAdmin –repStart ttdb1
```

This process defragments both the active and standby databases with only a few seconds of service interruption.
