How to speed up Multitenant CUSTOM database creation

Why has the PDB$SEED such a strange setup?I usually create my container databases for testing with the CUSTOM option of DBCA. That allows me to specify exactly the components I’d like to have – or not. But I realized two things during the CUSTOM creation: It takes very long. And in the alert.log I see resize operations especially with the PDB$SEED during dictionary view creation.… [ Read More ]

Oracle Open World 2018 – Recap, Slides, Impressions – and a BIG THANK YOU!

Oracle Open World 2018 is over since two weeks now. And for me it was the by far busiest OOW ever. We had 4 presentations, 4 labs, 12 customer CVCs, several other customer appointments … and I wouldn’t want to miss a single one. It was a lot of work – but meeting with these customers, the discussions after the talks, at the hallways, at the lab, that is so important for us.… [ Read More ]

Why Release Update Revisions (RUR) are tricky

A while ago we introduced Release Updates (RU) and Release Update Revisions (RUR). And despite the fact that not only we but also well known external experts such as Ludovico Caldara recommend to stay with Release Updates and simply ignore the Revisions, some people use them.

And my mates, especially Gerald Venzl, but of course also the involved developers and managers worked hard to have Oracle Express Edition XE 18c available for download.… [ Read More ]

Why is the October Patch Bundle from July?

Strange blog headline, isn’t it? Intentionally. Peter Lehmann mailed me a question – and asked more or less: Why is the October Patch Bundle from July? Sounds strange? It is strange …

Strange notation

Peter wanted to download the most recent patch bundle for Grid Infrastructure from October. And he found patch 28507693:

But he was wondering about the headline having the date of October 18, 2018 together with JUL 2018.… [ Read More ]

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.

What is _cursor_obsolete_threshold?

First of all, this is obviously an underscore parameter.… [ Read More ]
