Canonical Numbers

Having run into a bug in a custom form I thought I'd share the results.
Problem:
Oracle Applications allows users to work in a number format that is familiar to them, this is not a problem however and rather a smart feature. The problem come is when you want to save this info into the database and let different users view the data. The error arises when storing number values into a DFF attribute of a table which is a character. This means that when a european number (1.000,99) is stored in an attribute it will be stored as you see it. Now when a user viewing the "number" as regular (1,000.99) there will be an error as it is trying to convert the attribute to a number but it is not in a recognised format.

Solution:
Oracle to the rescue with FND_NUMBER.
To store a number into the attribute column use something like this:
attribute1 := fnd_number.number_to_canonical(p_number);
To read the number from the attribute column use this.:
p_number := fnd_number.canonical_to_number(attribute1);

Cancel or abort adop session

ADOP is in my opinion still pretty half baked. This is a critical tool that just isn't as intuitive as the old adpatch was. However we move with the times and get the hang of the new way of doing things. Along the way you might want to abort or cancel a patching cycling. With the two file systems and db editioning this can be a bit more to manage. I have learnt the hard way so you need to use the full cleanup after aborting a session.
adop phase=abort
adop phase=cleanup cleanup_mode=full

Creating new WLS domain ends with exit code 255

Cloning the instance I ran into this weird error. Was not sure what to do but after learning my lesson I dug through the error logs after seeing this in the adcfgclone log file.

Failed to initialize the application 'EBSDataSource' due to error weblogic.application.ModuleException after FNDCPASS apps change

Started testing password changes in our clone environments. Weblogic seems to love throwing you curve balls and when I changes the apps password with the below:
FNDCPASS apps/$APPS_PASS 0 Y system/system SYSTEM APPLSYS $APPS_PASS
I was not able to start the weblogic managed servers. A look in the log an I found this:
