That looks to me like 134Megs that it’s writing to tape. That’s an awfully long time to write that amount of data.
I would start by cleaning the tape drive and trying a brand new tape. I would also take a look at whether the job is waiting on locks while it’s running. It may also be worth while taking a look at the qhst log and the problem log to see if there’s anything else affecting your save.
The joblog is almost conclusive that this is indeed taking this much time with private authorities and probably has nothing to do with locks.
Review your authority scheme. Run PRTPRFINT *PCTFULL to see if any (non-IBM) profiles are collecting large numbers of authorities or if many profiles are all collecting authorities. You might review IBM profiles if ones that shouldn’t be collecting authorities, e.g., QPGMR or QSYSOPR, are being involved in your site’s objects. Some IBM profiles, e.g., QSYS will always have some large numbers.
If PRTPRFINT points to particular profiles, use DSPUSRPRF TYPE(*OBJAUT) to see what objects are involved.
If you have profiles that are out of line in terms of number of authorities, review how they become owners of or are privately authorized to objects. Break authorities into a set of profiles. Two profiles are better than one; three are better than two; but don’t get carried away and move into complexity of management. Note that ownership can often be held separately from other authorities.
If authorities are spread of many profiles, then begin removing private authorities from individuals and assign to a set of group profiles. Then make individuals members of those groups. For applications, see if authority areas can be represented on a set of authority lists, and then place the group profiles on the lists after removing private authorities from them.
Getting a scheme started is the hardest part. There can be tens of thousands of authorities to assign. A few well thought out and straight-forward CL programs can go a long way towards handling most of the work.
Once a scheme is started, it should be easy to keep in place and to extend. Ask specific questions here as difficulties arise.
