Sets the maximum length of time (in minutes) for recovery from system failure.
{ dbsrv10 | dbeng10 } -gr integer ...
All operating systems and servers.
When a database server is running with multiple databases, the recovery time that is specified by the first database started is used unless overridden by this option.
The value specified by the -gr option instructs the database server how often to perform a checkpoint. For example, if you set -gr to 5, then the database sever tries to perform checkpoints often enough so that recovery takes no longer than 5 minutes. However, if recovery is necessary, it runs to completion, even if it takes longer than the length of time specified by -gr.
The recovery time includes both the estimated recovery time and the estimated checkpoint time for the database.
