i upgraded the 10g(10204) RDBMS of R12(1206) to 220.127.116.11 using
Interoperability Notes Oracle EBS R12 with Oracle Database 11gR2 (18.104.22.168) [ID 1265232.1].
In the post install steps, It says to run catmgdidcode.sql , but I cannot find this script anywhere
Open an SR with Oracle Support.
But I see no value in doing what you did. 22.214.171.124 was an initial release and will require substantial patching. My recommendation would be to go directly to 126.96.36.199. But best practice would be to discuss this with Oracle Support and get them involved.
