That's great info. Many thanks... will look into the TDP 4.1... didn't know it
existed and SQL-BackTrack for Informix is quite an art to get it to actually
work. Can the TDP 4.1 restore from one machine to another??? our developers are
always wanting to put the production application server (either PeopleSoft,
Lawson or DataMart) onto a test box to recreate things. Seems to me that this
capability would not be affected by going to the TDP 4.1 as it is done via a
virtual host entry in the dsm.opt file. Also can the TDP 4.1 backup individual
data bases or tables from an application server? That is one advantage the new
SQL-BackTrack has over the older version.... there the Informix server had to be
DOWN to do this and that is seldom acceptable in a 24 hours production
environment... Thanks for any info - George

Subject: Re: expiring Informix logs ...?
Hi George, I am fine, busy as always... thanks for asking, how is San
Antonio ?
On this Informix issue, I guess Arnaud did not mentioned, and I didn't
realize at first that he was using SQL-BackTrack.
Tivoli nowadays has a new TDP for Informix 4.1 and works fine. We had three
Informix installations lately and we installed the TDP for Informix on all
of them (onbar - online, full, L0, & L1 backups) and things are working
great, without using SQL-BackTrack.
Again, and even with the TDP, all the DB data and the log data is expired
via TSM management and copygroup configuration because Informix can't
control and pass the expiration information to the API.
Informix, *SM API, and SQL BT versions is the main factor to tune and make
all three products to work appropriately.
Thanks.

Howdy Othonas! Hope you are doing well... haven't heard from you in a
while... I
think the problem with doing expiration and reclamation of backups made
with
SQL-BackTrack for Informix lies in the fact that if you use an older
version of
the product, the agent places a long time stamp on the filespace name
making
each name UNIQUE. Thus, you are left with a zillion unique filespaces, each
being an ONLY version of a db backup. This truly complicates expiration....
you
basically must go in and erase filespaces manually. With the newer version
of
SQL-BackTrack for Informix, it has the ability to delete back generation of
a
database. The generations term is used by BMC to distinguish between
versions as
each Informix backup is actually unique. It appears you can only retain 9
unique
generations at most; meaning if you backup up daily, the most you can
retain,
using the agent is 9 days worth. You can also expire using a date. These
features only became available on V.3... we are testing it now and it is a
pain
to install... BMC's directions are not great ;-(. Anyway, I am far from an
expert in these matters but I do have some experience with deleting
filesets
which is necessary, even if you put backups into their own management
class/copy
group. BTW: I have completed implimenting all the recommendations you made
and
just finished documenting the whole mess. During the course of the
documentation, I redid all management classes, copy groups and schedules to
make
them work the way we wanted and have everything revolving around our
logical
business day as you suggested. The redbook has some good tips on scheduling
stuff so that our admin processes are not overlapping with backups and
such.
Thanks- hope my rambling made some sense...

Arnaud hi,
I am a little troubled understanding why you say that "TSM is unable to
expire those logs". If you use a separate mgmt class and copygroup for your
logs, and your copygroup parameters are set properly, TSM will expire your
logs.
Maybe if you want to give us some more details of yr installation...
Cheers.

Subject: expiring Informix logs ...?
Hi everybody !
I come back on something that seems to be an old subject for *SM'ers :
we're using the Onbar API to ensure the backup of our informix logs, what
works really nicely, except we're facing a huge increasing of the number of
tapes used for this storagepool, due to the fact that TSM is unable to
expire those logs.
We tried to install the onsmsync utility a few month ago, which was
supposed to give us a rid of this problem, but I just saw today that it
isn't working at all !
Does anybody know if Informix or Tivoli found a solution to this problem
(new version of onsmsync ?), or if there is any other way expiring those
#@#@@... logs ?
I saw there is a c programm existing but I have no idea of c language so if
you know something easier, just let me know !
Thanks in advance ! ;-)
Arnaud
