When the Oracle DBA adjusts certain Oracle parameters, it
may be necessary to adjust DLM parameters accordingly. For example,
when the GC_DB_LOCKS parameter
increases, you should change the internal DLM Resources parameter
that is based on it. To make changed Oracle parameters effective,
you need to bring down and restart each Oracle instance. To make
DLM parameters effective, you must bring down and reconfigure the
cluster. For details, see "Configuring the Distributed
Lock Manager " in the chapter, "Building an OPS
Cluster Configuration."
