It’s time for my (and our) final conference this year: UKOUG in Liverpool. Liverpool? Yeah … the city of The Reds and The Blues (and Sunday is Merseyside derby time). The city of the greatest pop band ever, the Beatles. And well, the city which has an airport you can’t really fly into.… [ Read More ]
Direct INSERTs into HCC tables may be slower since Oracle 12.2
I work with several customers at the moment on their Oracle 12.2/18c “go live” projects. And one of these customers encountered a strange issue when comparing Oracle 11.2.0.4 to Oracle 12.2.0.1/18.3.0: Direct INSERTs into HCC tables may be slower since Oracle 12.2. Actually in this particular case, significantly slower. Read below why this can happen and how the workarounds look like.… [ Read More ]
How long can you provision database version X in the Cloud? – NEW
A few weeks ago I published a blog post about provisioning dates in Oracle Cloud environments for different databases releases. As we did an important update, I rewrite today: How long can you provision database version X in the Cloud? – NEW.
What has changed since the original post?
The key point in the previous blog post was:
“And by end of this calendar year, the option to provision an Oracle 12.2.0.1 instance will go away.… [ Read More ]

How to speed up Multitenant CUSTOM database creation
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. There may be reasons for doing so.… [ Read More ]
Oracle Express Edition XE 18c available for download
This was hard work right before Oracle Open World – and you had to wait a very long time. The last Oracle Express Edition we delivered was based on Oracle 11.2.0.2. Not exactly the most modern release these days. 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 ]

Current Support Status for Oracle Database Releases
Yesterday a former colleague from the UK pointed me to a very old blog post about the fact that no patches will be produced for Oracle 11.2.0.3 anymore. Which is a true fact.

Where does the database link SYS_HUB come from?
This blog lives a lot from customer’s feedback and updates. And these days, Nicolas Jardot from dbi-services in Switzerland sent me an email asking: Where does the database link SYS_HUB come from? And if he can delete it or if it has any deeper purpose. Neither Google nor MOS reveal a lot of useful information

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.… [ Read More ]
