IBM Assessment: DB2 9.7 DBA for Linux UNIX and Windows Sample Questions:

When this command is executed, the error shown below is generated:
SQL4970N Roll-forward recovery on database "PAYROLL" cannot reach the specified stop point (end-of-log or point-in-time) because of missing log file(s) on node(s) "0".

If there are currently 100 active log files and there is an error with archiving log file 1. What will happen when DB2 attempts to create log file 101?
A) The transaction that prompts DB2 to try and create log file 101 receives a "log full" error and is rolled back because the active log space is full. Since the physical log path is not full, the BLK_LOG_DSK_FUL parameter does not take effect, so the database does not appear hung.
B) DB2 will attempt to archive log file 1 to the regular archive location up to five times. If log archival still fails after the fifth attempt, the application will receive a "log full" error and at least one transaction will be rolled back.
C) DB2 will continue normal processing. It will create log file 101 while attempting to archive log file 1 up to five times. If the fifth attempt to archive log file 1 to the regular archive location fails, it will be placed in the FAILARCHPATH location until the regular archive location becomes available.
D) The database will appear hung because the active log space will be full and BLK_LOG_DSK_FUL is set to YES. Once log file 1 is archived, DB2 will begin normal processing.
