Re:Mixed page group

Discussion created by ca.portal.admin on May 6, 2005
Hi everyone,

I have a client that is thinking of using the mixed page group
facility.
In order to prevent any unnecessary heartache, I would like to hear
about any experiences of using the facility, of any ""what out fors"",
any
""gotchas"", etc.

TIA,
Laura Rochon

Re: [IDMSVENDOR-L] Mixed page group
"That would imply a database entry in the dbname table can include
segments of different page groups. When did that become a feature?

Re: [IDMSVENDOR-L] Mixed page group
"keep in mind - a subschema has ALWAYS (at least as far back as 10.2) been
able to have mixed page groups in them as long as any run unit did not
bind to multiple page groups. Now, since release 14.1, a run-unit can bind
to areas within multiple page groups. HOWEVER, when run units (such as the
aforementioned utilities) attempt to walk sets that cross page group
boundaries, as linda correctly states, the fun<?> begins.

in other words - having a subschema that maps to areas in multiple page
groups will not in and of itself burn you, but walking sets across those
page groups will indeed burn you.

RHDCSRTT decompile utility
"Anyone that has the DC COBOL program that I wrote to decompile the RHDCSRTT load module should NOT use it under release 16. Besides not generating the correct output, It appears to go into a CPU loop.

I'll send a message when I fix it.

Thanks, Paul McRoberts

Re: Mixed page group
"Our site uses mixed page groups extensively, in fact every subschema we
have has mixed page groups and we have never experienced the issue you
described.

Laura,

The only problem we've had is with utilities. Restructure is fine, but
you
shouldn't run Unload/Reload or Maintain Index using a mixed page group
subschema. The reason I say shouldn't is that sometimes it works and
other
times it fails with really bizarre error messages.
