In all blogs that I read, the solution is just to change the retention period to a reasonable value. Yes, it is true but in some case you need to go deeper in the analysis… Like you, I changed the retention period, ran the cleanup but finally, I had always a big database… Why, Why, Why? 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…
Recently, I have installed an Oracle 11.2.0.4 RDBMS on a server, and I wanted to install the latest Patch Set Update (PSU) 11.2.0.4.4 from October 2014. During the execution, I fell on the error “Archive not applied” and the job failed. This is how to quickly fix this issue. While installing the PSU 11.2.0.4.4 from October 2014 on my Oracle 11.2.0.4 database server, I experienced the following error: The following actions have failed: Archive not…

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…
Recently, I faced a TNS resolution problem at a customer. The reason was a bad environment setting: The customer called the service desk because of a DBLINK pointing to a bad database. The users were supposed to be redirected to a development database, and the DBLINK was redirecting to a validation database instead. The particularity of the environment is that development and validation databases are running on the same server, but on different Oracle homes, each…
Last week, when I was working on how to setup the Kerberos SSO for D2 3.1 SP1, I faced some issues due to a documentation that doesn’t seem to be up to date… In fact, our version is D2 3.1 SP1 and there is no specific documentation for SP1. 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 Franck Pachot . 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…
Recently, I worked on an Oracle database migration for a customer and I faced a strange behavior when accessing a file stored on the file system of the Oracle database. 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…
