EBS -- Discoverer 4i and Redhat/Oracle Linux 5 and above

Discoverer 4i may be still in use in your environments.
Especially if you have EBS 11i, you may have Discoverer 4i as it comes builtin with EBS 11i application tier.
One thing I want to remind is that, Discoverer 4i is not supported since 2006 and it is just not
working with Operating Systems like Redhat5/Oracle Linux 5 and above.

There is nothing we can do about it, as it is already documented in Error When Trying To Start Discoverer (Addisctl.Sh) (Doc ID 854976.1).
The error is:
8.0.6 $ORACLE_HOME/jre1183o/lib/i686/green_threads/ symbol errno, version GLIBC_2.0 not defined in file with link time reference (
Unable to initialize threads: cannot find class java/lang/Thread
Could not create Java VM

When you upgrade your OS to be Redhat / Oracle 5 or above, it is not certified at all.
The certified version is Dicoverer 10.1.2 and the solution for this is to upgrade Discoverer using note:
Note 313418.1 Using Discoverer 10.1.2 with Oracle E-Business Suite 11i.

This was the case in our last ODA X5 migration project, as we have migrated the EBS Application Tier from ORacle Linux 4 nodes to the Oracle Linux 5 VM nodes in ODA X5.
