You might need to increase the size of the EDGPDOX and EDGPDOY data sets (for example, in response to messages EDG9114I, EDG9115I, or EDG9116I).

The options for increasing the size of the PDA log data sets are:

1. Stop DFSMSrmm, reallocate larger EDGPDOX and EDGPDOY data sets, and then restart DFSMSrmm.
2. Reallocate the data sets without stopping DFSMSrmm. Suppose (for example) the current PDA log data sets are DFRMM.ZOS1A.EDGPDOX and DFRMM.ZOS1A.EDGPDOY, with both allocated with 20 cylinders, and you wish to reallocate them with 25 cylinders. You can do this with these steps:
   1. Ensure that your procedure for automatically copying the EDGPDOY data set to tape as a generation-data-group data set each time DFSMSrmm issues message EDG9117I has completed successfully.
   2. Rename DFRMM.ZOS1A.EDGPDOY to DFRMM.ZOS1A.EDGPDOY.OLD
   3. Allocate a new DFRMM.ZOS1A.EDGPDOY with 25 cylinders, following the requirements in Allocating the Problem Determination Aid (PDA) log data sets.
   4. Issue MODIFY DFRMM,PDALOG=SWAP

      At this point, you have DFRMM.ZOS1A.EDGPDOX allocated with 25 cylinders and DFRMM.ZOS1A.EDGPDOY allocated with 20 cylinders.

   5. Ensure that your procedure for automatically copying the EDGPDOY data set to tape as a generation-data-group data set each time DFSMSrmm issues message EDG9117I again completes successfully.
   6. Rename DFRMM.ZOS1A.EDGPDOY to DFRMM.ZOS1a.EDGPODY.OLD2
   7. Allocate a new DFRMM.ZOS1a.EDGPDOY with 25 cylinders, following the requirements in Allocating the Problem Determination Aid (PDA) log data sets.

   Now, DFRMM.ZOS1A.EDGPDOX and DFRMM.ZOS1A.EDGPDOY are both allocated with 25 cylinders.
