We recently upgraded an R12.1.3 instance to R12.2.9 and the custom applications for which adsplice was not run does not have an entry in the context file. These schemas were not listed by adzdsum script in the section that mentions running adzdreg.sql script. Since adsplice was already run for these custom applications in R12.1.3 we skipped running adsplice on R12.2 . ADZDREG.sql was also not run for these custom schemas. Do we have to run adsplice again after the R12.2 upgrade for the tightly integrated custom applications?
