Issue/Introduction
While the OPSVIEW 7.1.4 (OPSLOG Tracking) panel provides functionality to merge archived OPSLOG, merging OPSLOG can also be achieved without requiring access to the panels.
Environment
OPS/MVS
Cause
At the time of writing, CCLXCNTL member ARCHMERGE is a method used to merge archived datasets into a single OPSLOG but does not provide the ability to save profile views. Product support is providing this document as a process for customers who need to extract profile-modified OPSLOG for later review.
Resolution
Allocating Prerequisite Datasets
- Using a copy of CCLXCNTL(DEFDIV), create two OPSLOG DIV datasets used to store merged data:
- The first will store the unfiltered archive (ARCHLOG)
- The second will store the filtered data when this process completes (MERGELOG)
- Some adjustments to the existing DEFDIV program include:
- removal of SYSCHK1 definition and related code
- renaming of OPSLOG DIV dataset to reflect MERGELOG data
- resize OPSLOG DIV to a value to accommodate filtered data
- Using the sample below, allocate a physical sequential dataset, ensuring the file uses a RECFM of "FB" and LRECL of "640"
Adding ARCHLOG and MERGELOG to OPS/MVS
- Allocating OPSLOG DIV can be accomplished via the OPSVIEW 4.13 panel
- Use the "NEW" line command to add the OPSLOG DIV; be sure to specify "READONLY". Note the DDNAME value; to confirm, you'll have two: "ARCHLOG" and "MERGELOG"
- After adding, use the "ACTIVATE" column command to activate the OPSLOG for browsing and general use
Restoring Archived OPSLOG
- Using OPSVIEW 7.1.4, identify and note the archived OPSLOG being reviewed. For multiple OPSLOGs, use the OPSLOG MERGE utility prior to continuing
- Enter OPSVIEW 7.1.3, using the information previously gathered to generate an OPSLOG DIV:
- For "Archived OPSLOG" data set name, use the ARCHIVE model and version identified in OPSVIEW panel 7.1.4 (or the merged OPSLOG)
- For "Target OPSLOG" data set name, use the OPSLOG DIV defined in the prerequisite work
- Enter OPSVIEW 4.13. At this point, you should see your previously allocated MERGELOG DIV and your ARCHIVE DIV.
Extrapolating Archived OPSLOG
Using the REXX below, access the merged OPSLOG to pull the requested date and time ranges from the ARCHLOG. Following the completion of this step, enter OPSLOG and issue "LOGN MERGELOG" to switch to the merged OPSLOG populated by this step.

Additional Information
Usage Notes
- OPSVIEW panel access is required to configure this solution
- When selecting OPSLOGs, customers can use the OPSLOG MERGE Utility to store combine the OPSLOG prior to interrogation and offload using this process
- When using DEFDIV sample, some users may opt to code more than two OPSLOG DIV datasets; this is acceptable but not required
- This process can be ran in a batch job, assuming proper authorization is granted to the submitting user
- "ARCHLOG" and "MERGELOG" can be substituted with any eight-character NAME
- OPSLOG extract function details are examples; ensure OPSLOG contains date and time entries
