As I said in my last blog, the Alfresco Summit 2014 took place in London from October 7 to 9. So yeah, unfortunately yesterday was the last day of this amazing event. It’s the first time I had the chance to participate in an Alfresco Summit but I’m quite sure it will not be the last! I can’t tell what moment I preferred during this event because the Keynote (presentation of Alfresco One 5.0) was very…
You probably know about ‘nproc’ limits in Linux which are set in /etc/limits.conf and checked with ‘ulimit -u’. But do you know how to handle the monitoring and be alerted when you’re close the fixed limit? Nproc and ps Nproc is defined at OS level to limit the number of processes per user. Oracle 11.2.0.4 documentation recommends the following: oracle soft nproc 2047 oracle hard nproc 16384 But that is often too low, especially when…
I have recently posted on the way I like to extract execution plans. When we have Tuning pack, I suggest to get them with SQL Real-Time Monitoring as an active report. However, Martin Preiss said in a comment that he prefers the text format – easier to search, copy, and paste. And that’s a very good remark. We still need plain text. My point is that if you send me the active report, then I…

To find the correct queue destination I had to search the Queue Destination Name….

In this post, I would like to present not only what is new, but also what has changed (or not) and how to find it. The first step is to select all objects in SQL2008R2 and SQL2012 from the view sys.dm_os_performance_counters. Remarks: All object or counter definitions from this post come from msdn. Objects comparison The…

I spent three interesting days at the DOAG Konferenz 2012 – the German Oracle User Group’s conference. It was the 25th birthday and my first time as a DOAG Konferenz speaker.

I will talk about three areas: Oracle WebLogic 12c, monitoring & diagnostics, and licensing. Regarding WebLogic, Mr. Munz from munz & more described…
Although the managed server on which Java Virtual Machine Diagnostics (JVMD) manager is deployed is configured to use the the Node Manager like OMS and admin server, it is not started automatically with OMS. In this post, I will describe how to start JVMD manager automatically when the physical server boots. To implement the script, several steps have to be executed: Creation of a config file containing the encrypted password to connect to the NodeManager Test the…
