RE: Upgrading with no patches in the "base"?

I agree with the why not 19c comment.  

However back to the base question, I have seen lots of COTS vendors test their database upgrade or app against the base install of the database without extra patching.

Really means they are only testing fundamentals of the application against the database version, then they can later deal with possible perf tuning or bug changes later that they of course can simply blame on the Oracle Database and not their SW.

There are lots of applications that on move to a later version of the database that init parameters have to be changed including “_” parameters.

The testing method is to separate the variables

1. Testing the application against the new database version.
2. Testing the application against future security patches.

Yes if the patches fail then you have to determine what you are going to do with the app or work SEV1 with Oracle to make security patch and app work together.

"They will test this for a while, and if everything is fine, THEN they will apply the patch."  

And what if everything *isn't* fine? Then they *won't* apply the patch?  

Doesn't make sense.

Hi Michael,  

That sounds like black magic.  

If “for a while” implies two different maintenance windows, you end up with two test cycles and two disruptions instead of just one. If you get the opportunity to combat these voodoo practitioners in front of the management, the most persuasive argument would be that the database will be running without security and other critical patches for a while. Who’s going to take that risk?  

Last but not least, why not 19c?  

Best regards,

Hearing that an application is going to be upgraded from 12.1 to 12.2.  

Vendor is saying they will create a “blank, no patched” 12.2 $ORACLE_HOME, and then upgrade the database.  

They will test this for a while, and if everything is fine, THEN they will apply the patch.  

I’ve never heard of such a thing and have been working on Oracle databases since 1983, version 4.0.  

Is there logic in this? We try to keep all databases at N-1 on patching.
