During a migration project from an architecture 6i to 12c (coming from Windows - Client Server, going to ORACLE Cloud/Linux - Web Enable), many details have to be taken in care, such as :
- Naming files (all lowercase: icons, all dev/suite files, internal calls to fmb/rdf, attached plls,etc)
- Executing Reports (way different from 6i)
- Excluding deprecated components
- Some times even recoding JARs/DLLs used to communicate with others current components (ID card readers, POS terminals and others electronic devices integrated to that Software Solution) just to keep some important functionalities
- and some others
Also during this process we could apply a new refreshed look and feel remastering images and using color schemes offered by ORACLE, or maybe defining a curstomized one based on Client Brand Book. If solution was created using a object groups that can be inherid/subclassed (template/olb), it shouldn't be difficult.
But here I had small issue, during inherit properties to a Tab Canvas. After few days looking for a reason why some forms in 12c were displaying FRM-93652, and creating the form from scratch (replicating all code and functionalities) I found it (the way to avoid it): Not subclassing properties to a TAB Canvas.
As anyone can see, there weren't uncommun properties.
If someone has passed thru same situation or have an idea why could this happen, I would really appreciate any comments.
