Just in time for Oracle OpenWorld, a bunch of Fusion Middleware 12.2.1.0 products have been released, including:

Oracle OpenWorld 2015 : ACE Director Briefing – Day 2

ace-directorI started the day with a jog around the lake. Believe it or not, I got lost a couple of times. We checked out of the hotel and headed off for the second day of the ACED Briefing. :)

Once again, it’s mostly under NDA, but the agenda for the day was as follows.

My Oracle OpenWorld presentations

Oracle OpenWorld is just around the corner – I will have one presentation at OOW this year and another at the independent OTW event:

Connecting Oracle with Hadoop

Real-Time SQL Monitoring in Oracle Database 12c

Histogram Limit

A surprising question came up on OTN a couple of days ago:

Why does a query for “column = 999999999999999999” run slower than a query for “column > 999999999999999998” (that’s 18 digit numbers, if you don’t want to count them). With the equality predicate the query is very slow, with the range-based predicate perfomance is good.

Oracle OpenWorld 2015 : ACE Director Briefing – Day 1

ace-directorThe day started at 03:00 local time. I was in denial for about 60 minutes before I threw in the towel and got up. A couple of new release blog posts (VirtualBox 5.0.8 and MySQL 5.7) later, it was off to the gym again. I told you, it’s the new me…

After the gym I spent ages chatting to people in the foyer, whilst still stinking of gym and drinking coffee++. After getting cleaned up, I met up with a bunch of folks at 08:00 to walk across to head office for the first day of the ACE Director Briefing.

Should I monitor the MGMTDB database?

During the installation of Oracle Grid Infrastructure 12.1.0.1 you had the option to install the Grid Infrastructure Management Repository (GIMR) database MGMTDB. With 12.1.0.2, that option went away, and the MGMTDB database became mandatory. Given that it’s a database, the question of whether it should be monitored by Enterprise Manager was raised by a number of customers, and unfortunately a variety of different answers were forthcoming from different sources in Oracle.

Before we clarify that confusion, let’s have a look at what the MGMTDB database is used for. The best place to look for that is, of course, the documentation, but let me quote it here for the sake of clarity:

The Oracle Grid Infrastructure Management Repository:

Oracle OpenWorld 2015 : The Journey Begins

The day started at 05:30, which was not much different to normal, so that was good. A quick taxi ride to the airport was followed by a 1 hour sleep on the floor next to the departure gate. It’s wonderful having no shame. :)
