This is the most common issue. Look for your log file in the /tmp directory. This is related to the fenced user ID and file permissions on the ~/sqllib/splog directory. Ask your DBA to create a splog directory in ~/sqllib and grant full permissions on this splog directory to the DB2 fenced user. You can also create a splog directory in the fenced user’s home directory, and create a soft link at ~/sqllib/splog pointing to this splog directory. The logging stored procedures are designed to run as a FENCED process, and they run under the DB2 fenced user ID.
