After I cloned my production system I faced the following error when I run adadmin or adpatch
AD code level : [11i.AD.I.4]
The Applications System names per the APPL_TOP and the database are different.
Applications System name per the APPL_TOP: clone
Applications System name per the database: prod
If you continue, the Applications System name per the APPL_TOP will be ignored.
Do you wish to continue [No] ?
To solve it I had to run the following update statement on my clone database
update FND_PRODUCT_GROUPSset APPLICATIONS_SYSTEM_NAME ='clone' ;commit;
Hope that helped
