While the MOS article "Database Upgrade to 22.214.171.124 Fails with Error: “ORA-38802: edition does not exist”" has a pretty clear title, note ID 1995415.1 does not have a whole lot of details beyond the bug and that there is a patch associated to fixing this. Well looking at the bug has the details we are looking for since it seems like several objects, especially ORA$BASE, have no edition information so the installer is crashing!

Sure you might be saying to yourself, most I/O operations for Exadata are asynchronous and this only affects versions 126.96.36.199.2 and 188.8.131.52.1 of the Storage Server software so why is this a big deal? Do you know for sure you will not be upgrading to one of these versions of software? Do you think these versions are the only versions where this bug will crop up? Does this make you wonder how to monitor your disks for this kind of thing? Well the good news is that you can visit My Oracle Support document "Bug 20830449 - Disk corruption possible when a disk media error occurs while synchronous I/O is performed" for note ID 2009841.1 to find out which version of software has a patch available, and which one does not have the patch yet at this time!

Like most of you, I was intrigued after reading this MOS title "ARXGTR.rdf Posting Execution Report fails to regenerate" so I clicked on note ID 2010272.1 to find out this was the expected behavior after upgrading to R12.1.3 as the report is obsolete with another report taking its place.

Check out document ID 1969667.1 on MOS "EBS Procurement Accrual Accounting Analyzer" and download this new analyzer to run it at least once so you can see if there are any outstanding issues that need fixing in your environment.

Did you know that Oracle Database 12.1 introduces some new ways to sample dynamic statistics for query optimization? You are probably familiar with setting this in the 11gR2 world but 12c allows us to set this at a more granular level so it can be done at a statement level and you can find all the details at "Automatic Dynamic Statistics" on My Oracle Support from note ID 2002108.1 to see what has to be enabled for this to work.

Something that we take for granted is logging into the EBS application, but have you ever been curious about the how of it? I never thought about it until I read the MOS article "How to Customize Logon Behavior" found by note ID 30860.1 and learned about the logon trigger which passes username and password information from the application server to the database!

I harp on getting testing suites up and running all the time, and MOS document "AP And PO Accrual Report Did Not Generate Output After Upgrade" from note ID 2003582.1 is a perfect example of why since this would have been a simple item to notice if the report was plugged into a test suite. Visit the document to find out what patch is required to get the report working!

In terms of verifying patches, I am going to verify the patch associated from note "R12: Payables/Payments: Error: You may not remove the last payment from a payment instruction. Consider terminating the payment instruction instead." via document ID 2007497.1 so I can make sure we do not suffer from something like this in our own system!
