Which three statements are true about Clusterware resource debugging?
A. The crsctl command can be used to set debugging for Clusterware resources by using the following syntax:
crsctl set log resource "resource_name:logging_level".
B. Enabling logging for Clusterware resources can negatively affect cluster performance, so it should be used only when required.
C. After collecting debugging data for a specific Clusterware resource, terminate the collection of debugging data by issuing the crsctl set log resource "resource_name:stop" command.
D. Although the crsctl command can be used to dynamically affect logging for Clusterware resources, you can also configure resource debugging automatically by specifying a logging_ievel clause in the Grid_Home/log/hostname/admin/clscfg.ini file.
E. Debugging cannot be set for user-defined resources.
Correct Answer: ABD
Explanation/Reference:
Enabling Resource Debugging
Change the USR_ORA_DEBUG resource attribute to 1 for specific resources:
# crsctl set log res "ora.host01.vip:1"
After you capture all trace information, change the debug attribute back to 0:
# crsctl set log res "ora.host01.vip:0"
You can use an initialization file to configure debugging.
The initialization file name includes the name of the process that you are debugging (process_name.ini).
The file is located in the <Grid_Home>/log/host_name/admin/ directory.
Oracle Support may request that you enable tracing to capture additional information for problem resolution with Oracle Clusterware resources. Because the procedures described here may affect performance, perform these activities only with the assistance of Oracle Support.
The initialization file name includes the name of the process that you are debugging (process_name.ini). The file is located in the <Grid_Home>/log/ host_name/admin/ directory. For example, the name for the CLSCFG debugging initialization file on node1 would be: <Grid_Home>/log/node1/admin/ clscfg.ini
