OTD20056 Errors altering configuration – check system status
Explanation: Errors have been detected attempting to alter the current DB2
Manager configuration using the operator SET command. Other
messages will give details of the error encountered.

that the system configuration has not been altered erroneously.
OTD20057 Requested task tnnn does not exist - request ignored
Explanation: A sub-task specified in an operator command does not exist. The
request is ignored. ‘t’ identifies the sub-task type (‘D’ – disk reader;
‘H’ – housekeeping; ‘S’ – scheduler; ‘T’ – tape reader; ‘W’ – writer)
and ‘nnn’ gives the sub-task number.
Action: Ensure that the correct task number is specified in the operator
command. If necessary, use the DISPLAY command to display
details of all currently active sub-tasks.
OTD20058 Display processing completed
Explanation: Processing of an operator DISPLAY command has been successfully
completed.
Action: None. This is an informational message.
OTD20059 Task tnnn is not active - request ignored
Explanation: A request to purge a sub-task in the control region cannot be
performed because the task is either not initialized or already
terminated. ‘t’ identifies the sub-task type (‘D’ – disk reader; ‘H’ –
housekeeping; ‘S’ – scheduler; ‘T’ – tape reader; ‘W’ – writer) and
‘nnn’ gives the sub-task number.
Action: Ensure that the correct task number is specified in the operator
command. If necessary, use the DISPLAY command to display
details of all currently active sub-tasks.
