Which command will set full debugging for the communications and resource management components; of the CRS module on nodes host01 and host03?
The correct answer is C. crsctl set log CRS "CRSRTI:5,CRSCOMM:5" -nodelist host0l,host03. 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: crsctl…

Explanation
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: crsctl set {log | trace} module_name "component:debugging_level [,component:debugging_level][,...]" 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 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 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 crsctl set log crs "CRSRTI:1,CRSCOMM:2" -nodelist node1,node2 Oracle Clusterware Administration and Deployment Guide

Fatima Z.Apr 17, 2026The answer is C, and here is why it sticks. The tool is crsctl, your Clusterware ConTRoL key, not srvctl (that handles services) and definitely not ocrconfig (that baby touches the Oracle Cluster Registry, a whole different world). Picture a little colon as a volume knob, so CRSRTI:5 and CRSCOMM:5 are you cranking those two components up to full blast, level 5, "five means fully alive." The -nodelist flag is your guest list for the party, and only host01 and host03 got the invite. Lock in that pattern: crsctl set log, MODULE in quotes, COMPONENT colon LEVEL, then -nodelist with your targets, and you will never mix it up on exam day.
Yusuf A.Apr 11, 2026Tripped on B, but crsctl owns CRS log levels, it is C.
Samuel O.Apr 5, 2026crsctl is the right tool for this one, not srvctl or ocrconfig, and the syntax in C is exactly what the documentation shows: the module name in quotes, component names paired with their log level using colons, separated by commas. The nodelist flag lets you target specific nodes without touching the rest of the cluster, which is exactly how you would handle this in a real RAC environment when you only want to debug two nodes and leave the others alone.
Prof. SaraApr 27, 2026I keep coming back to D because "crsctl lsmodules crs" is how you enumerate the actual component names before acting on them, so piping that directly into "set log CRSRTI:5,CRSCOMM:5 -nodelist host01,host03" gives you one self-contained command that both identifies and configures the targets in a single pass. Every other option feels like it skips a step or uses the wrong utility entirely.
Yusuf A.Apr 30, 2026Appreciate the detailed breakdown, Prof. Sara, but the answer is C because crsctl set log crs takes the component list as its own argument directly, so you do not pipe lsmodules output into it, and the correct form keeps the subcommand, the component-level pairs, and the nodelist all within a single crsctl set log crs call rather than chaining two separate commands.
