EBS 12.2 / ISG enablement - isgDesigner.xml:369: Only deploy or undeploy is supported.

This blog post is for the ones who are trying to enable Integrated SOA Gateway on EBS 12.2.. This task is also done in 12.2 upgrade projects -- if you were already using ISG or planning to use it on your newly upgraded EBS 12.2.

You know what, the things are getting even more complex for EBS world.. I mean, for an upgrade you start with a document, then it redirects you to another one, and that another one redirects you to a different one, and then you come back to the first one and then you find yourself redirected to a new one :) Sometimes, it makes you feel like you are in some kind of a nested redirect loop :) 

So please be careful and do your own documentation while doing these things in your TEST environments..  Missing or ignoring a single thing will bring you some catastrophes later -- you can be sure about that : )

Well.. Documentation to follow for this task is as follows:

Installing Oracle E-Business Suite Integrated SOA Gateway, Release 12.2 (Doc ID 1311068.1)

Anyways; this issue appears in section 8, while configuring the REST services 

Remember -> SOA Suite is REQUIRED when using SOAP web services.

 -->

Section 8: Configuring Oracle E-Business Suite Integrated SOA Gateway for REST Services on Release 12.2.x Upgraded From Oracle E-Business Suite Release 12.1.

Here is the failed execution and the error..

ant -f $JAVA_TOP/oracle/apps/fnd/isg/ant/isgDesigner.xml -DserviceType=REST -Dactions=upgrade -Dverbose=ON

Error:

BUILD FAILED

/u01/oracle/PTK12_2/fs2/EBSapps/comn/java/classes/oracle/apps/fnd/isg/ant/isgDesigner.xml:369: Error:

Only deploy or undeploy is supported.

So it seems like there is something wrong with the isgDesigner.xml.. (despite the fact that you may be on  AD Delta 13 and TXK Delta 13.)

Don't push yourself hard for analyzing these types of issues, we already have a tool called ISG Setup Analyzer.

EBS Integrated SOA Gateway (ISG) Setup Analyzer (Doc ID 2462729.1)

Okay let's jump to the conclusion.. In this case, ISG analyzer will report you that ISG Consolidated Patch for 12.2 (21_4_3) (Patch) is missing in your EBS system.. So just install the patch and re-execute the failing ant command and that's it !:)
