The apar number is different for different versions and platforms. The fix
is available for version 3 mvs as PQ13256. I have applied the ptfs (UQ16502
and reqs) and the doc contains the following --
------
APAR PQ13256
APAR PQ13256
****************************************************************
* USERS AFFECTED: *
ALL ADSM Version 2 and Version 3 servers
****************************************************************
* PROBLEM DESCRIPTION: *
During a restore, when using the -pick option and -inactive
option, a long delay is experienced if the filespace is
has many thousands of files.
****************************************************************
* RECOMMENDATION: *
Apply the fixing PTF when available.
****************************************************************
A performance improvement has been made in the ADSM server
to narrow down the search for the files. When the -inactive
option is specified, the search is more general and takes
much longer. The -subdir=y adds even more to the search.
A new method of searching has been implemented.
The performance improvement affects the "upfront search time"
before files are sent to the client. Improvements will only
be seen if inactive files are requested to be searched.
The -latest option will also see these benefits. The
improvements experienced will vary greatly depending on the
number of files in the filespace and number of versions.
-----
I would be very interested to hear how well this fix works. Could those who
have reported horror stories please try the same restore again after the fix
is on, and report the results here?
Thanks,
