Peoplesoft plugin for OEM - part 1

In order to install OEM 10.2.0.5, we need to install OEM 10.2.0.3 as explain in the readme

So, let's install first OEM 10.2.0.3.

My OS is OEL 5.3 64-bits.

[root@opcenter cd1]# uname -a
Linux opcenter.phoenix-nga 2.6.18-128.el5 #1 SMP Wed Jan 21 08:45:05 EST 2009 x86_64 x86_64 x86_64 GNU/Linux
[root@opcenter cd1]#

However, you could hit the following error during the Enterprise Management installation, when starting the Apache server :

oracle@opcenter sysman]$ more /appl/oracle/oms10g/opmn/logs/HTTP_Server~1

09/08/23 18:37:44 Start process
--------
/appl/oracle/oms10g/Apache/Apache/bin/apachectl start: execing httpd
/appl/oracle/oms10g/Apache/Apache/bin/httpd: error while loading shared libraries: libdb.so.2: cannot open shared object file: No such file or directory

That's because the installed application is a 32-bits application, it needs the 32-bits libraries which does not exists natively on a 64-bits plateform.
It requires to install manually one more package, gdbm-1.8.0-26.2.1.i386.rpm (which add the library /usr/lib/libgdbm.so.2), and create a symbolic link to this new library :

[root@opcenter cd1]# rpm -Uvh gdbm-1.8.0-26.2.1.i386.rpm
warning: gdbm-1.8.0-26.2.1.i386.rpm: Header V3 DSA signature: NOKEY, key ID 1e5e0159
Preparing...                ########################################### [100%]
   1:gdbm                   ########################################### [100%]
[root@opcenter cd1]# ln -s /usr/lib/libgdbm.so.2 /usr/lib/libdb.so.2

Apart from that, it is taking time, but no issue to install OEM 10.2.0.3 on OEL5.3 64-bits.
The next step is the upgrade to OEM 10.2.0.5, then the real target is the installation of the Peoplesoft plugin for OEM...

Enjoy,

Nicolas.
