Setting database parameter values
The values that you assign to certain database configuration (DB CFG) parameters affect the behavior of IBM® Data Server Manager (DSM).
The table below lists the recommended values for these parameters:
| Database Parameter | Description | Recommended value |
|---|---|---|
| MON_REQ_METRICS | For basic data collection of statements, activities, workloads, etc. | BASE |
| MON_ACT_METRICS | For basic data collection of statements, activities, workloads, etc. | BASE |
| MON_OBJ_METRICS | For data collection of database objects, such as TABLE, TABLESPACE, etc. | BASE |
| MON_RTN_DATA | For data collection of stored procedure | BASE |
| MON_LW_THRESH | For data collection of blocking and waiting connections | 30,000,000 (microseconds) |
| MON_DEADLOCK | For data collection of blocking and waiting connections | history |
| MON_LOCKTIMEOUT | For data collection of blocking and waiting connections | history |
| MON_LOCKWAIT | For data collection of blocking and waiting connections | without_history |
Note: Enabling Locking Event Monitoring data option in Settings > Monitoring Profiles
page, will update the MON_LW_THRESH, MON_DEADLOCK,
MON_LOCKTIMEOUT, and MON_LOCKWAIT parameters of the target
database to the recommended value.
