MAXGROUPS
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. Oracle GoldenGate 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
