APEX is invalid after upgrading to 12.2 – ORA-20001

Posted on February 11, 2020 by Mike.Dietrich APEX Flaws and Pitfalls 0

We are running the AutoUpgrade-for-RAC beta test since last week. And the first issue one customer encountered … is neither an AutoUpgrade nor a RAC issue. It has to do with APEX and SPATIAL, and missing grants. APEX is invalid after upgrading to 12.2 – ORA-20001

Be aware of database options selections for PDBs in DBCA

Posted on May 15, 2018 by Mike.Dietrich Single-/Multitenant 6

I did blog about several things-to-know with DBCA (Database Configuration Assistant) in the past. And one issue came up in our internal mailing list the other day. Be aware of database options selections for PDBs in DBCA. Missing one or the other “click” may bring you in trouble later on. I blogged about this already a while ago but this was only part of a larger post: Create Multitenant Databases with DBCA – Things to Know.

ORACLE_MAINTAINED attribute can be pretty helpful

Posted on March 21, 2018 by Mike.Dietrich General 9

You may have seen my two blog posts about Oracle supplied objects and Oracle supplied user schema and roles a few days ago, One person commented asking about what to do with these. And I agree: It looks a bit harsh to deal with two external files to query Oracle supplied stuff. But actually (as Patrick Hurley commented as well) there is a much easier way since Oracle Database 12c to deal with objects created and supplied by Oracle: the ORACLE_MAINTAINED attribute can be pretty helpful.

Oracle APEX (Application Express) Clean Up in Oracle Database 11.2-12.2

Posted on July 27, 2017 by Mike.Dietrich APEX Removal 17

Oracle APEX (Application Express) clean up in Oracle Database 11.2-12.2 is fairly simple and straight forward. With the upgrade to Oracle Database 12.2.0.1 Oracle APEX does not get upgraded automatically anymore. If necessary you should upgrade Oracle APEX upfront of afterwards. But please do keep an eye on the APEX certification with Oracle Database 12.2.0.1 to avoid any issues:

Last week I’ve had an interesting discussion with a customer about the certification of APEX and Oracle Database 12.2.0.1.

I did a bit of research and emailing – and thanks to the APEX team – this is the source of truth for APEX certifications.

Is your APEX version certified with your Database release?

See MOS Note:1344948.1: Application Express (APEX) Database and Web Server Certification Reference:

Use the correct download to patch APEX from 5.1.0 to 5.1.1

Posted on May 1, 2017 by Mike.Dietrich APEX 0

When you plan to upgrade Oracle Application Express (APEX) from version 5.1.0 to 5.1.1 please be aware to download a patch from MOS instead the 5.1.1 version from OTN.

The text on the OTN page is a bit misleading – and a customer I work with downloaded the wrong version which led to a failed upgrade – even though the scripts seem to be made for this patch upgrade.

Even though the page says “This is a cumulative patch set for Application Express 5.1.0” the page offers you a full install and not …

Java in the database – OJVM non-rolling patches – OJVM Removal

Posted on June 22, 2015 by Mike.Dietrich JVM Removal 30

Question:

How can I find out if Oracle’s JVM is used in my database?

Answer:

This is unfortunately not as trivial as I thought initially …
Let’s start with:

MOS Note:397770.1

Until Oracle version 11.2 or later, there was no way to confirm if Oracle JVM is not actively used in the database.

However, what can be said is:
1) If there are non-Oracle schemas that contain java objects, then 3rd party products or user defined java programs could be actively using the Oracle JVM.
2) If there are Oracle schemas, other than SYS, that contain java objects, then
