By | Database Administration & Monitoring | No Comments

A customer asks me to find all sql logins enabled on servers where windows authentication only is enabled. The goal is to clean sql logins on all servers through the CMS (central management server). In some cases, sql logins are created even if the authentication is set to “Windows authentication only mode”. I think that this query is interesting and I will just share it with you. DECLARE @value INT USE [master] EXEC xp_instance_regread N’HKEY_LOCAL_MACHINE’,…

How to read XML database alert log?

By | Database Administration & Monitoring | No Comments

Since Oracle 11g, Oracle maintains two copies of the database’s alertlog in ADR: a flat text file in the sub-directory trace and an XML like in the folder alert. I had a case recently at a customer where the log.xml was moved to another place and compressed for archiving reason. As the regular text file was not containing old data, the goal was to exploit the archived XML -like file. When the file is still located…

ACFS 12.1.0.2 on Oracle Linux 7.1

By | Database Administration & Monitoring | 2 Comments

Recently we wanted to create an ACFS filesystem on a brand new 12.1.0.2 GI installation on Oracle Linux 7.1. According to the documentation this should not be an issue as “Oracle Linux 7 with the Unbreakable Enterprise kernel: 3.8.13-33.el7uek.x86_64 or later” is supported. The “or later” is the important point. In our case: uname -a Linux racp1vm1 3.8.13-55.1.6.el7uek.x86_64 #2 SMP Wed Feb 11 14:18:22 PST 2015 x86_64 x86_64 x86_64 GNU/Linux   Should be fine as…

You enter the specific information of your system and at the end of the PostgreSQL installation,…
