Rather than using a database trigger simply add more volumes to the
database:

Tsm> Define dbvol e:\db1.dsm formatsize=20000 (this will add a 20 GB
database volume on drive e:.  The Unix file syntax will apply if you are
on a Unix based TSM server)

Then extend the database into that volume:

Tsm> Extend db 20000 

Both the define and extend are required to ensure that you actually use
the space in your database.  Typically, you want to have several db
volumes for performance reasons so perhaps rather than one at 20GB  you
have two at 10GB...

For the scratch tape issue: only one way around that problem: check in
more scratch tapes:

1. Put a bunch of barcode labeled blank/scratch tapes into the library
slots.

2. issue the following command:

Tsm> label libvol libraryname search=yes overwrite=yes
labelsource=barcode checkin=scratch

This will label and check in scratch tapes.

If you have already labeled scratch tapes, then put them into the
library and:

Tsm> checkin libvol libraryname search=yes status=scratch

Or use the bulk port on your library (if you have one...)

Tsm> checkin libvol libraryname search=bulk status=scratch

Help checkin libvol and help label libvol will show you all the options
of these commands.

And it's probably time to take a TSM training course.  Head to our
website for details...

Subject: [ADSM-L] Database resizing and changing minimum scratch tape
requirements

Hello All,

I appreciate any help you can provide for the commands to do the
following:

 

1)  Increase the database size due to the following error:   

 

The database utilization is too high. Condition (98.1 > 90)

Recommendation: Consider a database space trigger or increase the size
of the database.

 

2)  Decreasing the minimum number of scratch tapes required, due to the
following error:

(Note, I just checked in five tapes as scratch on Friday, and the
library is completely populated)

 

There are not enough scratch volumes available. Condition (2 < 5)

Recommendation: Check in some scratch tapes.

 

Thanks,

Kerry
