Oracle Database upgrade fails with error “UnsatisfiedLinkError exception loading native library: njni10”

We have received following error when trying to upgrade database from 10g R2 10.2.0.2 to Oracle 10g R2 10.2.0.4 using “dbua” (Database upgrade assistant) tool

The server Operating system is recently upgraded to newer version and suspected the issue might be related to library relink and ran “relink all”.

The “relink all” failed with below errors.

Solution: Finally figured out that the issue is related to missing 32bit RPM "glibc-devel (32 bit)" and after installing the RPM the database upgraded successfully to Oracle 10g R2 10.2.04.
