When DB2 wants to dump, specifically where do I get to specify the
primary and secondary space allocations for that dump?
This part is well documented. Issue:

Has anyone (else) found they need to manage dump performance with e.g. DB2
???.
We had a dump storm a while back - over 30 DB2
The way I did it was to use a naming convention for the SVC Dump name in the
dynamic allocation for dump. No other data set was to use this naming
convention which was SVCD.taskid.sysid.date.sequential#. Then I had a clist
that was run as a batch job to collect some basic doc from the dump and

Shmuel (Seymour J.) Metz,
Now that I am at a new company and we have finally insourced our
production system I have a question on how we set esoterics. I was always
under the impression that we could use SMS and set the esoterics. Here is
an example of what's currently in the Dataclass ACS routines.
FILTLIST TAPE90
We have recently begun a tapecopy process from IBM VTS's to STK VSM's. We
have run into a few files that on the IBM side exceeded the max vol count
for discrete profiles, but when trying to copy them to STK there is an
issue and the discrete profile only allows them to go 42 volumes. On the
IBM
Since the 42-volume limit for a discrete tape dataset profile, I doubt that
the tape management system could over-ride this. You may have been given
some special usermod to RACF to disable the abend that occurs when the
42-volume limit is reached, and simply allow more volumes to be created. But
yes it does.

The task:
move existing Adabas datasets from 3380 volumes to 3390's.
Total DB size is approx. 0.4 TB, planned outage window is whole weekend,
so there's a lot of time.
I was told it requires two jobs: backup and restore.
However I'd like to RTFM. What manual should I start ?
Any gotchas ?

I saw my last 3380 over 15 years ago.

Restore it.

Some shops choose to emulate 3380s on modern Dasd to avoid converting
geometry-sensitive data. At my previous job we had a few emulated-3380s
that contained BDAM files

You can always READ without any risk of corrupting data, so if you know that
data is being update only from say ONLY one sysplex, the risk of corruption
should be minimal. Just time when you read the data to ensure you get the
'latest' version.
There is an exposure even if you only do updates
In the VTOC, a DSCB may be rewritten to update the last reference date
even for a dataset opened only for INPUT.
I have firmly believed, for over 15 years, if you are sharing DASD you need GRS.
If you are sharing across PLEX's, you need MIM (not MII anymore).
Period. End of statement.

To transfer file from one SYSPLEX to another SYSPLEX, we can use Flashcopy
or Shadowimage, so different SYSPLEX read/update different volumes. Yes,
it is safe, but we have to change our TWS application procedures to do
Flashcopy.
