In all blogs that I read, the solution is just to change the retention period to a reasonable value.

My first step for this analysis, is to see in the SSISDB, the Disk Usage by Table Reports from…

In a recent project I faced the following situation: One the one hand I had to execute scripts on a customer’s workstation while on the other hand I had to integrate the results of these scripts into a report on my own workstation. The question was how to efficiently do this without sending dozens of mails to myself. One solution would be to create one script which produces all output and send the results by…

SQL Server 2014: sys.dm_exec_query_profiles, a new promising feature

By | Application integration & Middleware | 3 Comments

Among the hidden features provided by SQL Server 2014 there is a very interesting dynamic management view named sys.dm_exec_query_profiles. This feature will help the database administrators and experienced developers to troubleshoot long running queries in real-time. I’m pretty sure you had to deal with the following questions: When will this query finish? What percentage of total workload is performed by this request? Which steps are the longest? Before SQL Server 2014 it was impossible to…

The particularity of the environment is that development and validation databases are running on the same server, but on different Oracle homes, each…

In consequence, I read the D2 3.1 Installation Guide and the D2 4.0 Installation Guide. The first time I read the D2 3.1 documentation, I found…

By | Database management, Oracle | 3 Comments

Did you ever encounter unexplained Oracle lock issues? They may be coming from unindexed foreign keys (which is worse in 11g). It’s not easy to monitor. Of course you can check Oracle locks from V$LOCKED_OBJECT, but that is a solution only for locks that remain. Some Oracle locks are there only for a short duration. How do you check which lock is acquired by a statement? Event 10704 is the solution. I’ll show some examples in order…

The database has been migrated on a new server, and consolidated with existing databases. Several jobs are running into the database and need to access the file system to read or write some files. A particular file is received daily from a remote job over…
