In Response To: directing onbar to disk? (GARY PRICE)

In onbar there is command to define the pool.
In our case we are using ISM.
The command for ISM to perform the backup of logical log to disk is :
ism_add -device /usr/backup/ism_log -type file
ism_op -label disk_for_log -device /usr/backup/ism_log -pool ISMLogs

Where "file" tells the system that location will be to disk.
/usr/backup/ism_log is a directory location where the logical log will be
written to.
Ensure that you have enough space else you will run into logical log full
situation.
Where disk_for_log is the label name link to /usr/backup/ism_log directory
and it is for Logical log indicated by -pool ISMLogs

In TSM there should be some command to do that, but I am not sure. Hope
all this help.

Subject
directing onbar to disk? [10352]

I'm migrating an Informix enviroment to the datacenter of our parent
company.
They use Netbackup as the storage mgr (we use TSM). The Netbackup agent
for
Informix is installed and onbar configured to use it. Netbackup is taken
down
everyday from 1100-1300 for 'maintenance'. This, of course, causes any log

backup to fail; if there is a batch job running, the logs will fill.

Due to the above, I'd like to be able to direct onbar to write to disk
first
and let Netbackup take care of getting it off to tape later. We do this
with
TSM, using a 100GB disk pool. Our Oracle databases have a parameter
(LOG_ARCHIVE_DEST) which allows you to specify a disk location for log
offloads. I've not found anything in the Informix doc. that would allow
this
to be done using Onbar (maybe I've missed something?).

Any help, as always, would be appreciated.
