How to switch back from Oracle Kernel to RedHat?
Hello friends,
We have RHEL 7.5 server with latest updates. We needed to install Oracle 12 DB on it so chose "easy method" of installing "oracle-database-server-12cR2-preinstall-1.0-3.el7.x86_64.rpm" and then installed oracle DB. Everything went smooth and all OK but later we noticed that it has Oracle Kernel ver 4.14 uek installed instead of using Redhat's 3.10 ver. and using updates from Oracle rep. I managed to configure it back to use updates from Redhat (as we have support from RH) but not sure how to switch the kernel back to Redhat's by keeping all the software (esp Oracle) intact. Redhat is NOT providing any support as this server running Oracle kernel.
We can see both Oracle kernel entries & Redhat entries in grub.conf but not sure If I can simply boot Redhat 3.x kernel with oracle too working fine.
Could anyone please advise how to switch back to RH kernel without breaking anything else? I know rebuilding the server from scratch and not choosing "preinstall rpm" method will fix that but that's a too long process.
Many Thanks!

apache::session::store::oracle
Apache::Session::Store::Oracle(3pm) User Contributed Perl Documentation Apache::Session::Store::Oracle(3pm)
NAME
Apache::Session::Store::Oracle - Store persistent data in a Oracle database
SYNOPSIS
use Apache::Session::Store::Oracle;
my $store = new Apache::Session::Store::Oracle;
$store->insert($ref);
$store->update($ref);
$store->materialize($ref);
$store->remove($ref);
DESCRIPTION
Apache::Session::Store::Oracle fulfills the storage interface of Apache::Session. Session data is stored in a Oracle database.
SCHEMA
To use this module, you will need at least these columns in a table called 'sessions':
id varchar2(32) # or however long your session IDs are.
a_session long
To create this schema, you can execute this command using the sqlplus program:
CREATE TABLE sessions (
id varchar2(32) not null primary key,
a_session long
);
If you use some other command, ensure that there is a unique index on the table's id column.
CONFIGURATION
The module must know what datasource, username, and password to use when connecting to the database. These values can be set using the
options hash (see Apache::Session documentation). The options are DataSource, UserName, and Password.
Example:
tie %hash, 'Apache::Session::Oracle', $id, {
DataSource => 'dbi:Oracle:database',
UserName => 'database_user',
Password => 'K00l'
};
Instead, you may pass in an already-opened DBI handle to your database.
tie %hash, 'Apache::Session::Oracle', $id, {
Handle => $dbh
};
The last option is LongReadLen, which specifies the maximum size of the session object. If not supplied, the default maximum size is 8 KB.
