This is forgetting that disks integrate since years the S.M.A.R.T technology. Good point, it can easily be adressed in Linux command line through smartctl What is S.M.A.R.T. exactly? S.M.A.R.T., which stands for Self-Monitoring, Analysis and Reporting Technology (also called SMART), is a monitoring system for and integrated in…
I recently talked to a customer about SnapManager, its recommendation on the number of databases and about a way to prevent the creation of more than 35 databases. The NetApp recommendation is no more than 35 databases on a single volume. The reason is that SQL Server has to use 4-5 worker threads per database in order to manage the freezing and un-freezing I/O for each database. Look at this note: More information on this…

Once a replication environment is set up, it’s rarely forever. Adding tables to an Oracle GoldenGate replication group with minimal impact to the current replication is quite a difficult operation. This posting should help you with this task. In the example below, tables from schema G001 will be added to an existing replication setup from the database PROD1 to REP1.

Introduction Often some times after having setting up a replication environment, it is needed to add additional tables to the replication, where the additional tables have dependency with the current replicated tables. This tasks must be implemented without disturbing the current replication environment Explanation In this example the below tables from schema G001 on Database PROD1 will be added, to an existing Replication from PROD1 to REP CFG_ADV_COND CFG_NARRATIVE_TEMPLATE CFG_REG_REPORT_RULES CMN_LOOKUP CMN_USER_LOGIN Stop the replication…

Last month I was confronted to a very interesting and strange problem while deploying a Cloud Control 12c infrastructure. One of my monitored server was a SuSE Linux Enterprise Server (SLES) 64 bits on which a 11.2.0.3 Oracle database was installed. The x86_64 cloud control 12c agent has been deployed on this server with the standard Cloud Control 12c agent deployment procedure (not the scope of this post). However despite several trials to configure the…
Database Vault solution allows to create rules that manage access to database. Among these rules there is what is called in Database Vault “Rule Sets”. These logic components are written as PL/SQL functions to return Boolean results.
If rule expressions do not match the user context, the access is refused and a specific message can be configured in order to warn the user that he is not authorized to access this specific object. These expressions can be for instance related to the client IP address, the session username, the time or date and many other things.
Nous avons dans les articles précédents vu comment installer PostgreSQL et quels étaient les composants d’une base. Nous abordons maintenant le point de l’action
sur le moteur avec deux outils orientés administration de la base, généralement utilisés par les DBAs. Il s’agit de psql et de PgAdmin. Nous aborderons aussi dans cet article la configuration de connexion au travers des fichiers de configuration du serveur.
For sure you already used, or at least heard about, the HP Smartstart Kit. This especially includes the storage management part ACU: Array Configuration Utility. This tool is pretty straightforward to configure the storage and RAID volumes before installing an HP server.
However did you know that these features are also available in command line? This is what hpacucli does…
