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,…

Migrating to Oracle OEM Cloud Control 12.1.0.2.0

By | Database management | One Comment

I recently upgraded from Enterprise Manager Cloud Control 12.1.0.1.0 to the most recent version 12.1.0.2.0. This document describes the migration procedure and the different problems encountered. The first point to know when you are about to upgrade an existing Enterprise Manager Cloud Control 12c is that Oracle Installer will create a new Middleware home. Thus, you will need to have enough free disk space (around 7 GB) on your system to be able to upgrade…

Java Virtual Machine Diagnostics: Starting/stopping JVMD manager

By | Application integration & Middleware | No Comments

Although the managed server on which Java Virtual Machine Diagnostics (JVMD) manager is deployed is configured to use the the Node Manager like OMS and admin server, it is not started automatically with OMS.

To implement the script, several steps have to be executed: Creation of a config file containing the encrypted password to connect to the NodeManager Test the…

By | Technology Survey | No Comments

Like Apple, Oracle keeps the secret over Oracle Database 12c, but tends to deviate from the Silicon Valley secret culture. However, we can relay all that we heard to you Over the past 10 years, Oracle has worked on plenty of state of the art topics like compression, in-memory operations, scalability, and this is still true for Oracle Database…

OOW Day 2: Oracle Database as a Service

By | Technology Survey | One Comment

Another day in the San Francisco Bay discovering the Oracle Cloud, but without clouds in the sky :=) Today I went to a session describing a customer case study on Oracle database cloud with Enterprise Manager Cloud 12c. Prior to deploying the database cloud, UAT activities charged the DBA team for at least 3 days (implies cost). The IT team decided to implement DaaS (Database as a Service) because of: The self-provisioning feature reduces the…

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…

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.
