Error While Loading Shared Libraries: libdb.so.2 on RedHat Linux 5

Error While Loading Shared Libraries: libdb.so.2 on RedHat Linux 5

After clonning (or installing) an Oracle Applications Release 12.0 or 12.1 instance on Linux 5, an error may occur while starting up the Apache service. The error would be this:

You are running adapcctl.sh version 120.6.12000000.4
Starting OPMN managed Oracle HTTP Server (OHS) instance ...
adapcctl.sh: exiting with status 204


After review the HTTP log file. The error is very clear about the missing soft link. It would show this error:

/u01/apps/AJI_apps12/ora/10.1.3/Apache/Apache/bin/apachectl startssl: execing httpd
/u01/apps/tech_st/10.1.3/Apache/Apache/bin/httpd: error while loading shared
libraries: libdb.so.2: cannot open shared object file: No such file or directory

Soft link libdb.so.2 is missing.


To solve this issue, Shut down all Oracle Application Services

As root user, create a soft link as follows:
# ln -s /usr/lib/libgdbm.so.2.0.0 /usr/lib/libdb.so.2

Start up all Oracle Application Services
