Step 5: Back Up Version 8.1.x or 8.2 Files
Use your existing preconversion housekeeping jobs or other JCL to back up ChangeMan ZMF files and clear log files for the 8.1.x or 8.2.x release that you are migrating from, before you begin converting files for version 8.3.
The following table lists the files you should back up. To accomplish this task, use the sample JCL members in the vendor CMNZMF CNTL library that was distributed with the ZMF 8.1.x or 8.2.x instance that you are migrating from.
| Last DSN Node of the File to be Backed Up | Description | Type | Vendor CMNZMF.CNTL Job of Your Existing, Preconversion Instance |
|---|---|---|---|
| CMNRECV | Package Master, Short-Name Component Master, and Long-Name Component Master Forward Recovery File | VSAM | CLEARRCV Note 1 |
| CMNLOG | Activity Log | VSAM | CLEARLOG |
| CMNDELAY | Delay file | VSAM | See Note 3 |
| IADSP | Impact Analysis | LDS | LDSBKUP |
| IALOG | Impact Analysis Forward Recovery Log | QSAM | LDSLOGR |
| CMNSVSM | Staging Versions Site Master | VSAM | SVBKUP Note 4 |
| CMNSVOM | Staging Versions Object Master | VSAM | SVBKUP Note 4 |
| CMNSVDM | Staging Versions Delta Master | VSAM | SVBKUP |
| CMNSVAM | Staging Versions Archive Master | VSAM | SVBKUP |

Note 1: Please read the comments in the supplied sample JCL members.
-
Note 2: The BACKUP sample job will do the files listed, and optionally has a step to take an image copy of SQL Process Admin tables if so desired.
-
Note 3: There is no sample job for backing up the CMNDELAY file. Use IDCAMS with output QSAM file attributes RECFM=VB, LRECL=5000, BLKSIZE=32700.
-
Note 4: These jobs do the same work as the second step of the BACKUP job. You may use either.
