• ACS displays an alert message when the difference between the physical and actual size of the view
database is greater than 10 GB and less than 50 GB. Also, an automatic database compress operation
is triggered when the size of the database exceeds 111 GB to avoid disk space issues.

If the log recovery feature is not enabled and the ACS view database compress option is enabled,
an automatic database compress operation is triggered only after enabling the log recovery
feature when the size of the database exceeds 111 GB to avoid disk space issues.
–
If the log recovery feature and the ACS view database compress option are enabled, an
automatic database compress operation is started to avoid disk space issues. The log collector
services are shut down during this operation and will be up and running after the compress
operation is completed. Since you have log recovery feature enabled already, any log messages
that are received during the database compress operation are recovered after the log collector
services are up and running.

If the log recovery feature and the ACS view database compress options are not enabled, ACS
does not trigger any database compress operation. But, if the size of the database exceeds 111
GB, an automatic database compress operation is triggered only after enabling the log recovery
feature to avoid disk space issues.

If the log recovery feature is enabled, and the ACS view database compress option is not
enabled, an automatic database compress operation is started when the size of the database
exceeds 111 GB to avoid disk space issues. The log collector services are shut down during this
operation and will be up and running after the compress operation is completed. Since you have
log recovery feature enabled already, any log messages that are received during the database
compress operation are recovered after the log collector services are up and running.
Note It is recommended to perform DB compress during the maintenance hours. DB compress may take long
time depends on the database size. DB compress should be done after the purge operation gets
completed.
