Valid For

GLOBALS

Description

Use the MAXGROUPS parameter to specify the maximum number of process groups that can run in an instance of Oracle GoldenGate. The Manager process checks this parameter to determine its resource allocations. The GGSCI process checks this parameter to control the maximum number of groups that it allows to be created.

Each Replicat thread in a coordinated Replicat group is considered to be a group in the context of MAXGROUPS. Therefore, the value of the MAXTHREADS option of COORDINATED in the ADD REPLICAT command (default is 25), plus the number of other Replicat and Extract groups in the Oracle GoldenGate instance, cannot exceed the MAXGROUPS value, or ADD REPLICAT returns an error.

The actual number of processes that can run on a given system depends on the system resources that are available. If those resources are exceeded, Oracle GoldenGate returns errors regardless of the setting of MAXGROUPS.

Default

1000 groups
