Steps to Enable CAS Log in IBM IIS 11.3

Step 1 - Set the CC_MSG_LEVEL environment variable and restart ASBAgent
1. Make a backup of the dsenv file (typically located at /opt/IBM/InformationServer/Server/DSEngine/dsenv)
2. Edit the dsenv file, adding the following lines to the end of the file: CC_MSG_LEVEL=1; export CC_MSG_LEVEL
3. Source and export the dsenv file
4. Ensure no users are importing metadata, viewing data or testing connections (i.e. no design-time activities are on-going)
5. Restart the ASBAgent. To restart the agent:
     1. Become root
     2. cd /opt/IBM/InformationServer/ASBNode/bin
     3. Execute ". ./NodeAgents_env_DS.sh". Notice the period at the beginning.
     4. Execute "./NodeAgents.sh restart"
    
Step 2 - For IIS versions 11.3.0 or later
1. If your IIS version is 9.1.2 or earlier jump to step 6.
2. Become root on engine tier.
3. cd /opt/IBM/InformationServer/ASBNode/conf
4. Add the following 1 line at the tail of file asbagent-logging.properties com.ibm.iis.cas.level=ALL
5. The log file directory is /opt/IBM/InformationServer/ASBNode/logs

Step 3 - Remove CC_MSG_LEVEL from the environment and restart the ASBAgent
1. Remove the lines you added to the dsenv file.
2. Restart the ASBAgent using the steps above.
