OEM 13cR3 - Silent Installation with DB 18c Templates - Part 1

In this blog I am going to cover installation of OEM 13cR3 silent with Templates on DB 18
I will be referring to my previous blogs here to keep the length of this Series minimal.
This is a 2 Part blog

1. The first part covers Database Installation and DB Creation
2. The second part which can be found here covers the part where we install the OEM.

Part 1
The step 1 is obviously to have your database installed, you can refer to my blog on Database Installation Silent of 18c 

Once the Installation is complete, download the template for Database 18c for OEM 13cR3 from below link
https://www.oracle.com/enterprise-manager/downloads/db-templates-13c-release3-downloads.html

Unzip the template in $ORACLE_HOME/assistants/dbca/templates

$ cd /u01/app/oracle/product/183/db/assistants/dbca/templates
$ unzip -qq /u01/Template/18.1.0.0.0_database_template_for_em13_3_0_0_0_linux_x64.zip

Next Install EMREPO using the template

$ /u01/app/oracle/product/183/db/bin/dbca -silent -createDatabase -templateName  18_1_0_0_0_Database_Template_for_EM13_3_0_0_0_Small_deployment.dbc -gdbName EMPRD -sid EMPRD -sysPassword oracle -systemPassword  oracle

Once the DB is Installed and running, set SPFILE parameters according to your need and set  all the spfile parameters as specified in below link for an 18c Installation.

After that do a Bounce of the Instance.


This completes my database creation.
Ensure you have a listener running which registers the DB Services
IN the next part of the blog we will setup the OEM.
