Oracle Enterprise Manager 12c: Administration Groups & Template Collections

By | Database management | No Comments
 

This document describes the implementation of the
administration groups and template collections with Oracle Enterprise
Manager Cloud Control 12c.

 

Administration Groups (improvement of Grid 11g Target Groups) and Template Collections improve the management of targets and ease the monitoring strategy.

 

Administration Groups allow to organize targets according to several criteria. For instance the Lifecycle status of the target (prod, dev, integration), the location of the target can be used as criteria. The main goal is to apply common settings (i.e monitoring settings) to targets having the same purpose.

 

The first point about administration groups is to define a clear concept and the hierarchy between these several criteria. The administration groups must be organized in a convenient way according to the company organization. In the next chapter we will present how to handle the hierarchy existing in Cloud Control 12c in order to change it in an administration group organization fitting to the company structure.

The target property is used to implement automatically the target in the appropriate administration group.

PostgreSQL : Qu’ai-je installé, Où sont mes données ?

By | Technology Survey | One Comment
 

Dans mon dernier article sur PostgreSQL, j’ai présenté l’installation du logiciel en explorant les 2 solutions suivantes, l’installation Debian et l’installation EntrepriseDB. Ces deux installations créent immédiatement un cluster de base de données, Debian nous imposant le point de stockage et EntrepriseDB nous proposant de saisir une destination. Je vous propose maintenant d’explorer ce qui a été installé sur votre disque à la mise en route de ce cluster de base et d’analyser les différences entre les deux installations.

Stéph@TechEd 2012: Episode 1 – the Pre-Conf. Seminar

By | Technology Survey | No Comments
 

 This morning, I was very happy to go to my first TechEd. Between the 10 seminars, as I said yesterday, I started with SQL Server 2008R2/2012 performance, tuning and optimization session. The thing is that we had just one session for the whole day. I will not copy the presentation of the 2 speakers (Thomas LaRock and Denny Cherry) who presented remarkably this session despite the failure of air conditioning during the morning. Fortunately, it…
