Warning: The following setup  is only specific to Oracle Linux 6.

The issue mainly caused by  missing 'oravis - nproc 2048' setup in the /etc/security/limits.d/90-nproc.conf for Oracle Linux 6.

The following is the correct setup example:

etc/security/limits.d/90-nproc.conf

* soft nproc 1024
root soft nproc unlimited
oravis - nproc 2048                <---add this line: use the oravis  which you used as the DB installation owner instead of ovavis.

Note: The default value on a Oracle Linux 6 system shows as 1024.
In Oracle Linux 6, a new file /etc/security/limits.d/90-nproc.conf, sets the maximum number of processes to 1024 for non-root users.

The value for max forked process is actually read / taken from /etc/security/limits.d/90-nproc.conf file instead of /etc/security/limits.conf file.

SOLUTION

To implement the solution, please execute the following steps:

1. cd /etc/security/limits.conf
increase * hard nofile 65535 to * hard nofile 65536

2 Make a backup for /etc/security/limits.d/90-nproc.conf before changing.

3 Modify the entry in /etc/security/limits.d/90-nproc.conf 

From:

# cat /etc/security/limits.d/90-nproc.conf
* soft nproc 1024
root soft nproc unlimited

To:

* soft nproc 1024
root soft nproc unlimited
oravis - nproc 2048

4 Run the RDA - Health Check / Validation Engine Guide ( Document 250262.1 ) for the installation to ensure healthy report output for the following rule set:

APPS ebs122_lin Oracle E-Business Suite Release 12 (12.2.0) Preinstall (Linux x86_64)
