Oracle Enterprise Manager 12c: creation and management of administrators through emcli

By | Database management | No Comments

Cloud Control 12c (and the former Grid Control 11g) offers the possibility to create administrators and manage their privileges through the “emcli” command line utility. The main advantage of this method (based on scripts) is to be able to reproduce the creation of the users as soon as a new Cloud Control infrastructure must be built up (for instance in order to migrate Grid Control 11g on Windows to Cloud Control 12c on Linux). Indeed,…

Oracle Enterprise Manager 12c – Database Target remains in Pending state (SLES x86_64 target)

By | Database management | No Comments

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…

Replace a voting disk is so easy with Grid Infrastructure 11.2 & ASM!

The current ASM disk group (redundancy normal) had 3 disks : two located in one data center and one disk in another data center. The goal was to replace one voting disk (from the most used Data Center) with one disk coming from a third Data Center.

Oracle RunInstaller crashes while installing Cloud Control 12c on OEL 5.7

By | Database management | 7 Comments

A few days ago I downloaded the Cloud Control 12c binaries for Linux x86_64 from the Oracle Technet.

My friend, Hervé Schweitzer, configured an OEL 5.7 VM for test purpose and I was quite eager to install this new software. I checked the O.S settings, the required parameters, aso …, everything was fine. My OMS repository database (11.2.0.3) was ready. Unfortunately, as soon as I started the installer, it directly crashed.
