This is a short post about something I wrote a while ago. I wrote a monitoring tool (haven’t we all?) and wanted to add a capability to scan log files (in this case alert log, etc.) so this is the solution I came up with
I usually don’t work with the local version of EM. I haven’t used DB Console in 11g and below so much, and I used EM Express in 12c even less. But when a colleague contacted me not too long ago and said that Oracle stripped down a lot of functionality in EM Express, I had to check it out.
In an Oracle Data Guard configuration, the primary and standby databases can have different configurations. It’s very common to have a smaller server for the standby database (less CPUs, less memory, etc.) and it’s quite trivial to configure. But what about RAC?
This is not my tip, but Connor Mcdonald‘s. I attended a couple of his sessions at Open World 18 and had to write about this small but really useful feature that he mentioned (thanks Connor).
Oracle Open World was interesting like every year. This year, Oracle started talking about features that will probably be in Oracle 19c (which is the last 12.2 release). The rumor says that it will be out in the first half of 2019 (somewhere around April-May).
As you might know, I didn’t attend a lot of sessions, but managed to gather some information about expected features (given Oracle’s safe harbor of course).
In the past, during OOW Oracle published the official dates of OOW of the following year, but in the last few years they stopped doing this, so we can’t be sure when OOW19 will be. There was a lot of unknown about OOW18 until the official dates were released (and 2018 is the first year the User Group Sunday was removed and it became a 4-day event)
This topic has been sitting in my backlog for a long time and I finally decided to write it. Analytic functions are not so new anymore (they’ve been around since Oracle 8i), but they are still a very powerful tool.
This is based on a real case I had quite a few years ago. A client came to me with a question regarding a graph they had to generate.
