EBS R12 (12.1) installation failed at Post Install Checks on Linux : libdb.so.2


This post is from our Oracle Apps DBA Training where trainees install Oracle E-Business Suite (R12) on our servers remotely.

We use Oracle Linux 5.5 to install Oracle Apps and on installing version 12.1.1 installation completes but at post install check failed with above screen shot (Post validation checks failed for HTTP Server).

If you get error like above then

1. Check status OHS logs under OPMN (OHS is managed by OPMN) 

In log $LOG_HOME/ ora/ 10.1.3/ opmn/ HTTP_Server~1.log (where LOG_HOME is $ORACLE_BASE/inst/apps/$SID_[hostname]/logs )

/u01/oracle/PRD1211/inst/apps/PRD1211_iamdemo07/ora/10.1.3/Apache/Apache/bin/apachectl startssl: execing httpd
/u01/oracle/PRD1211/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



Looked at Bala’s blog and

1. Installed gdbm using Yum and here

yum install gdbm

2. Created softlink for libdb.so.2 pointing to libgdbm.so.2

ln -s /usr/lib/libgdbm.so.2 /usr/lib/libdb.so.2

3. Start OHS (Set environment & then use OPMNCTL to start OHS)

. $ORACLE_BASE/ apps/ apps_st/ appl/ APPS[SID]_[hostname.env]


adopmctl startall

4. Click on retry on post install validation steps
