How to become/learn Oracle Apps DBA R12.2 : Part I

I started this blog 9 years back with first post as How to become Oracle Apps DBA (back then it was 11i) and with 225 comments, this is still the most common question I get in mail or on this blog.

We are starting our new batch for Oracle Apps DBA training (R12.2) from August 8, 2015 and first thing we cover is Architecture of Oracle E-Business Suite.  If you are learning (getting trained) on Oracle E-Business Suite on your own then first thing you should learn is Architecture of Oracle Apps.

As shown below Oracle E-Business suite is Three Tier Architecture

a) Database Tier : With Oracle Database where data resides
b) Application Tier : With Application & Web Server where business logic resides
c) Client Tier : browser based client from where end user access application

Note: Till Oracle E-Business Suite R12.1 (prior versions include 12.0 & 11i), Application Tier uses 10g Application Server (or 9 for some versions of 11i). From Oracle E-Business Suite 12.2 onwards Application Tier is deployed on Oracle WebLogic Server as application Server.

I faced the issue during installing siebel IP2015 ses.

Following the Docs:
http://docs.oracle.com/cd/E63029_01/books/SiebInstUNIX/SiebInstCOM_InstSES4.html#wp3576303

Step7
./runInstaller -jreLoc /home/oracle/jdk1.7.0_79 -invPtrLoc /siebel/oraInventory

Step11 with error
Enter Oracle Home Name:SES_HOME
Oracle Home Location/siebel/15.0.0.0.0/ses

Error:
oracle.sysman.oii.oiii.OiiiInventoryDoesNotExistException: The inventory pointer location /siebel/oraInventory is either not readable or does not exist

/siebel/oraInventory is existed and onwner is my install user.

I don’t why the issue is occurred.

Do you have any advise on this.

Thanks.
