I had to perform a duplicate database between 2 ODAs and was always facing an ORA-65500 at the begin of the RMAN operation. Looking a bit deeper in the log outputs pointed me out that it was due to some changes in the way RMAN makes the duplicate in 12c and cluster resources management.
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…
Having worked for several years as an Oracle DBA, I decided to have a look at the PostgreSQL database and see how it functions in comparison to the Oracle Database. The “Enterprise DB” graphical installation of PostgreSQL 9.3 is quite easy and rather fast. Under Linux you run the graphical installer, dialog boxes lead you through the installation process. You enter the specific information of your system and at the end of the PostgreSQL installation,…
The Microsoft Techdays 2013 took place on 12-13 November at the Congress Center in Basel and on 18-19 November at the Beaulieu Congress Center in Lausanne. With more than 400 participants in Lausanne and around 1’000 participants in Basel, the largest technology event Microsoft in Switzerland was a great success. You can follow all the presentations from Lausanne or Basel. In this blog, I will summarize the presentation of SQL Server 2014: les nouveautés by…
Today was the first day of UKOUG Tech13: 4 days about Oracle Technology. This year, 7 streams started today (3 last years). I also had a slot to give my presentation about the Optimizer behavior in 12c. The day started with a little delay in registration: My collagues Pierre and Philippe were not correctly registered and didn’t get their badge right away, but everything was solved before the start of the sessions. Speaker time I…
Starting with Oracle Database 12C Release 1 a set of new administrative privileges that are more task oriented are available.
Before Oracle 12c it was needed to have the SYSDBA privilege to make a backup, to monitor the Data Guard status or to administrate some features of Oracle Transparent Data Encryption. Starting with this new Oracle release it is not anymore the case. We can grant limited administrative privileges to operate an Oracle 12c database.
Diese Frage habe ich in den letzten Jahren öfters gehört. Zumindest seitdem die DBAs Oracle Datapump verwenden anstatt des alten Export/Import Tools. Angeblich war es früher mit dem Import-Parameter-Tool „INDEXFILE“ viel einfacher. Tja, die Wahrheit ist: Mit Datapump geht es noch leichter! Dies möchte ich anhand eines ganz normalen Datapump-Export–Files verdeutlichen. In folgendem Beispiel handelt es sich um einen einfachen Schema-Export, der wie folgt erzeugt wurde: oracle@vmoel58:/u00/app/oracle/admin/DB112/etc/ [DB112] cat expdp_SalesApp.par SCHEMAS=sh DIRECTORY=data_pump_dir DUMPFILE=expdp_SH_2013-02-17.dmp LOGFILE=expdp_SH_2013-02-17.log PARALLEL=4 oracle@vmoel58:/u00/app/oracle/admin/DB112/etc/…
Well, this last day really was funny! We met some old friends (they will recognize themselves) and also Oracle guru Jonathan Lewis. We must confess Larry Ellison really has good friends. His America’s cup boat is really amazing (see picture below) as was last night’s party. Today, we were really tired and the speakers too. Most of today’s content was a review of what Pierre and I reported during the week. It fits exactly Tom…
I have had the pleasure to go the Real World Performance presentation with the famous Tom Kyte of the Ask Tom blog, Andrew Holdsworth, Head of Oracle’s Real World Performance Team, and Graham Wood, the legendary Oracle Database performance architect. This was not a session but more a show like in a theater! Each of them had a precise role, DBA, chief of development team, system administrator, and Enterprise Manager Cloud 12c showing us in…
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.
