Behavior Change in Oracle 18c/19c: No symbolic links for Data Pump directories

Most of you may have recognized the desupport of UTL_FILE_DIR with Oracle Database 18c. Reason is mostly that UTL_FILE_DIR opens a lot of possibilities to do insecure things. But this has another effect which may not be obvious to you. There’s a behavior change in Oracle 18c/19c: No symbolic links for Data Pump directories. Read further to learn more about it.

UTL_FILE_DIR Desupport

In Oracle Database 18c we announced the desupport of UTL_FILE_DIR initialization parameter. But as you can read as well in the Database Upgrade Guide, there’s this remark:

Automatic SQL Plan Management in Oracle Database 19c

Automatic SQL Plan Management in Oracle Database 19cWhen you upgrade to a new database release, there will be changes. Some are obvious, others are not. This one is somewhere in between because it is documented quite well but not very well known yet as far as I see. I’m talking about the Automatic SQL Plan Management in Oracle Database 19c.

DBMS_JOB vs DBMS_SCHEDULER

Back in the 10g days, we introduced a new interface to run and monitor jobs in the database: The scheduler. The scheduler with DBMS_SCHEDULER is way more powerful than the old job interface.

When and how should you change COMPATIBLE?

When and how should you change COMPATIBLE?

COMPATIBLE is an almost mystic parameter. It has a default setting for each release. But if you try to find more information what it really does, you won’t be very happy. And in reply to my previous blog post about whether you need to change COMPATIBLE when you apply an RU, I received the following question: When and how should you change COMPATIBLE?

How long will Oracle Database 12.2 be supported?

This question sounds very simple: How long will Oracle Database 12.2 be supported? Right? But I learned at a customer site recently that the information about the support periods for Oracle 12.2 may puzzle people sometimes. Hence I thought some clarification may be useful.

Lifetime Support Policy Brochure

First of all, when you have a look into the Lifetime Support Policy brochure the answer you’ll read there is:

  • Premier Support until March 2023
  • Extended Support until March 2026

Premier Support Extension for Oracle 19c – and more

Wait a bit. Oracle Database 19c is not out yet (only in beta right now) but how can we initiate a Premier Support Extension for Oracle 19c already? Well, Oracle 12.2.0.1, Oracle 18c and Oracle 19c all together sail under the cover of the “Oracle 12.2 Release Family” and hence have a common support frame.

Oracle 12.2 and higher: Set _cursor_obsolete_threshold to old default

Sometimes development groups change default parameter settings because it fits well for a specific feature. This has happened with _cursor_obsolete_threshold in Oracle Database 12.2. But there’s now an official recommendation for Oracle 12.2 and higher: Set _cursor_obsolete_threshold to old default.

What is _cursor_obsolete_threshold?

First of all, this is obviously an underscore parameter. And usually the policy is: Don’t change underscore parameters unless either you clearly understand what you are changing. Or unless Oracle Support (or another Oracle authority) advises you to do.

Drop public synonym XMLCONCAT prior to upgrade

Thanks to my team mates, Cindy and Hector, who alerted me on this newly detected issue. When your database has been upgraded from release to release, it could happen that a public synonym XMLCONCAT exists.

Drop public synonym XMLCONCAT prior to upgrade
