Using context file from currently set applications environment:

/data02/EBS_R12.1/apps/inst/apps/JAY_CRP/appl/admin/JAY_CRP.xml

Unable to read the value of s_file_edition_type from the context file

Verify location and rerun this script.

Cause:- 

If you are running the ETCC utility to determine which patches are missing on R12.1.X before the upgrade. 

At that point "s_file_edition_type" doesn't exist in the context_file because it only exist on 12.2 tech stacks not on 12.1.

Solution:

To resolve the issue first we need to lay down 12.2 software using rapidwiz, then create the upgrade file system by running rapid install.

Once above steps are done , now run checkMTpatch.sh script after sourcing 12.2 environment it will complete successfully.

$ cd /fs1/EBSapps/appl

$ . ./APPS_JAYCRP.env

 $ sh checkMTpatch.sh
