Explanation:
crsctl set log
Use the crsctl set log command to set log levels for Oracle Clusterware.
You can enable debugging for Oracle Clusterware modules and their components, and for resources, by setting environment variables or by running crsctl set log commands, using the following syntax:
Syntax
crsctl set {log | trace} module_name "component:debugging_level
[,component:debugging_level][,...]"
Usage Notes
You can set log levels for various components of the three modules, CRS, CSS, and EVM. If you choose the all option, then you can set log levels for all components of one module with one command. Use the crsctl lsmodules command to obtain a list of components for each module. Enter a comma-delimited list of component name-log level pairs enclosed in double quotation marks ("").
The log_level is a number from 1 to 5 that sets the log level for the component or resource, where 1 is the least amount of log output and 5 provides the most detailed log output. The default log level is 2.
To set log levels for resources, specify the name of a particular resource, or a comma-delimited list of resource name-log level pairs enclosed in double quotation marks ("").
To set debugging levels on specific cluster nodes, include the -nodelist keyword and the names of the nodes, as follows:
crsctl set log crs "CRSRTI:1,CRSCOMM:2" -nodelist node1,node2
