Changing the Size of the Active Missions File

Note: Online users must not access the Online facility while the size of the Active Missions file is being changed. You should stop all access to the AMF until the process is complete.

Perform the following steps to change the size of the AMF:

1. Rename the current AMF—which is the input file for the copy operation and its backup file—using, for example ISPF 3.2 or 3.4.

   Note: The backup Active Missions file suffix is AMB.

2. Perform the following steps:
   1. Enter ICE and select Customization.
   2. In the Customization screen, set Product ID to CTD.
   3. Select major step 6, "Customize Control-D Data Set Parameters."
   4. Select minor step 2, "Control-D Data Set Parameters."
   5. Change the size of the new AMF by modifying the value of the AMFSIZE parameter from, for example, 1100 blocks to 1200 blocks.
   6. Select minor step 3, "Save Parameters into Product Libraries."
   7. Select minor step 4, "Format the Active Missions File."
   8. Set the TYPE parameter to NEWAMF/NEWAMB.
   9. Submit the job and create a new Active Missions file (with the suffix NEWAMF).
3. Edit the CTDCAMF member in the Control-D JCL library. Change the OLDAMF parameter to match the name specified in Step 1, as follows:

   //CAMF EXEC CTDAMF,OLDNAME=’old-dsname’,NEW AMF=’new-dsname’

    COPY

   //

   where

   • old-dsname is the name specified in Step 1.
   • new-dsname is the new DSN with the suffix NEWAMF.
4. Run the CTDCAMF utility to copy the current AMF to the new AMF. You must terminate the utility with a return code of 0.
5. Restart the Control-D monitor and resume operations.
