WAIT

z/OS DFSMSdss Storage Administration
SC23-6868-01

Use this procedure when DFSMSdss suspends activity while it is waiting for a condition to be satisfied, yet it has not issued a message to tell why it is waiting. Ensure that the wait is not caused by your having specified WAIT subparameters that are too large.

Example: 5695DF175 RA10 WAIT function

Procedure: To determine the keywords for type-of-failure and function, follow these instructions:

  1. Use WAIT as the type-of-failure keyword if all DFSMSdss tasks were in a WAIT state.
  2. Obtain an abend dump of the WAIT state. Ensure that the job control language (JCL) has a SYSABEND, SYSMDUMP, or SYSMDUMP data definition (DD) statement.

    _______________________________________________________________

  3. Follow these steps to find the function keyword:
    1. Record the relative task identifier. The relative task identifier is the number in parentheses (ttt) that immediately follows the message identifier in message ADR006I. Message ADR006I is printed when a DFSMSdss task begins. For example:
      ADR006I (ttt)-mmmmm(yy), date_and_time EXECUTION BEGINS
    2. Locate the tasks that are active (message ADR006I without a matching ADR013I). Message ADR013I is printed when a function ends. For example:
      ADR013I (ttt)-mmmmm(yy), date_and_time TASK COMPLETED
    3. Use CNTRL as the function keyword if no tasks are active, or if more than one function is active. See Module keyword.
    4. Check prior messages for an ADR101I message with a task identifier that matches the one that you found in step 3.a. For example:
      ADR101I (ttt)-mmmmm(yy), TASKID xxx HAS BEEN ASSIGNED TO COMMAND 'command'
      The command identified in this message is the function that is executing at the time that the wait started. This function name is the function keyword.

    _______________________________________________________________

You have finished when you have identified the function keyword for the WAIT type-of-failure. To identify the maintenance level of the module that failed, refer to Module keyword.

Guideline: For the DFSMSdss stand-alone restore program, the module keyword is always ADRDMPRS. If you select this keyword, see Maintenance-level keyword.
