I have installed the GnoRPM from a .rpm file on Redhat 9. The installation went through without issues. But when i try to invoke it as 'root' by typing "gnorpm" in a shell prompt or in Run command area , I get the following error msgs.

"db4 error(11) from dbenv -> open: Resource temporarily unavailable"
"Cannot open package index using db3 - Resource temporarily unavailable(11)"

While logged in as root, when I try to run it from the menu, the following msg is displayed.

"The password you typed is invalid, please try again"

Guess the problem is with the RPM db itself, the output for "rpm --rebuilddb" is a similar msg
"error: db4 error(16) from dbenv->remove: Device or resource busy"

Any help to fix this issue is appreciated.

thanks
Manoj.

Chec you don't have any proccesses running that are accessing the rpm database (if possible a rebot should make sure) then rebuild the database again:
rm -f /var/lib/rpm/_*
rpm --rebuilddb
