Ted,
You can receive this error if your RPM database is corrupted. You can recover by using one of two methods.

If you haven't done anything since the error occurred, you can rebuild your rpm database by issuing the "rpm --rebuilddb" command.

If the rebuild fails, then you have to rebuild the database from scratch. To do that,
1) copy the contents of the /var/lib/rpm directory to a backup location.
2) delete the __db.00* files from the /var/lib/rpm. There should be three of them.
3) Re-initialize the RPM database by issuing the "rpm --initdb" command.
4) Rebuild the RPM database by issuing the "rpm --rebuilddb" command.

If all of these fail, then you'll need to restore the /var/lib/rpm directory from a backup copy or contact RedHat on how to repair the damaged RPM database.

The details of the failure in RPM are documented on the Red Hat site at the following URL:
http://www.rhn.redhat.com/errata/RHEA-2004-010.html.

We've added checks in the Linux PSP to minimize the chance of the RPM database corruption. Normally, the cause can be traced to an application that attempts to access the RPM database while the database is locked. This is one of the reasons why we shutdown the agents, health driver, and SNMP during our installation. We know that the HP agents and SNMP attempt to access the RPM database every couple of minutes to update their MIB tables. If an attempt to install software is done while these checks of the RPM database occur, it will randomly cause the corruption you see.

Hope this helps.

Thanks! If I could give you 15 points I would! I appreciate the prompt and accurate reply.

The "rpm --rebuilddb" command worked and I was able to load the software.
