Issues while Upgrading IAS to 10.1.3.5 for R12.1.3

Always remember to set $INST_TOP/ora/10.1.3/{SID_hostname}.env before starting IAS Upgrade.

Issue 1) While doing IAS Upgrade to 10.1.3.5, the following error occurred,

The runInstaller cannot found the opmn port number in opmn_port.
File 10.1.3_ORACLE_HOME/install/opmn_port is null.

To resolve above issue, followed "IAS Upgrade - OPMN Port Information is Unavailable (Doc ID 1545145.1)"

1. Check for correct opmn port of current instance:

$ADMIN_SCRIPTS_HOME/adopmnctl.sh status -port

2. Add it to file 10.1.3_ORACLE_HOME/install/opmn_port:
opmn_port = <the value returned from step1>

3. Click 'OK' in runinstaller to continue the patch application.

Issue 2) oc4jadmin password could become an issue when installing 10.1.3.5 Techstack software in Oracle 12.1.3 EBS. Its important to know that we are providing right oc4jadmin password.

I didn't know password for oc4jadmin, as I also tried to check my luck with some standard passwords like welcome1, welcome, oafm, secret with below command, but not worked 

How to verify:

java -jar $IAS_ORACLE_HOME/j2ee/home/jazn.jar -checkpasswd jazn.com oc4jadmin -pw *****
Unsuccessful verification of user/password pair.

***** = oc4jadmin password

The message should be successful. If not the password can be changed in system-jazn-data.xml file, for which I used "How to reset "oc4jadmin" password for standalone OC4J version 10.1.3 (Doc ID 360130.1)" 

1. Shutdown all opmn services :

cd $ADMIN_SCRIPTS_HOME
adstpall.sh / adopmnctl.sh stopall

2. cd $ORACLE_HOME/j2ee/home/config

Here ORACLE_HOME= Oracle Application server home, ie, 10.1.3 HOME
Take a backup of system-jazn-data.xml and edit the below content:

<user>
<name>oc4jadmin</name>
<display-name>OC4J Administrator</display-name>
<guid>93E5A2505D1511DEBF8E89BC12E10097</guid>
<description>OC4J Administrator</description>
<credentials>!mynewpassword</credentials>
</user>

Marked in bold is the details to be changed and that is the password. Note an ! mark has to prefixed with the password.

3. Start all opmn services.

Whenever autoconfig is run after this activity, the password changes to encrypted format.

To Verify Again,

java -jar $IAS_ORACLE_HOME/j2ee/home/jazn.jar -checkpasswd jazn.com oc4jadmin -pw *****
Successful verification of user/password pair.

Issue 3) In Post-Installation, while Configuration Assistants run to apply One-Off Patches, I had faced several issues w.r.t. opatch rollback because of bug conflict. (you may or may not face this issue)

Hence checked in /etc/OraInventory logs. Rolled-back some opatches manually, also renamed/moved some files (eg. like  which were creating problem while rolling back some patches. After that applied required patches manually OR clicked on Retry button, and completed installation successful.
