Enable Trace / Debug

Below are several ways to enable tracing and debugging for Oracle RAC resources.

1)  SRVM_TRACE:  Enable Tracing for cluvfy, netca, and srvctl

      export SRVM_TRACE=TRUE

      srvctl config database -d db11g1

You can dynamically enable logging (level 1 to 5)

2)  Enable debug to capture clusterware resource:  crsctl set log res "<resource name">:1"
     crsctl set log res "ora.registry.acfs=1"
     Set Resource ora.registry.acfs Log Level: 1

After you collect all the trace, disable the trace:  crsctl set log res "<resource name >:0"

crsctl set log res "ora.registry.acfs=0"

Set Resource ora.registry.acfs Log Level: 0

3)  You can enable dynamic debugging for CRS, CSS, EVM, and other clusterware sub components.  The  crsctl lsmodules css, crs, evm commands use to list the module's components.
