Oracle Enterprise Manager 13c and Always On Monitoring

In this cloud-era it’s almost weird to explore stuff on-premises, but I did….  In this case a slightly Higher Availibility configuration of Oracle Enterprise Manager (OEM) that doesn’t  cost anything, is not disruptive to the existing configuration and gives a tiny bit more confidence during patching of OEM : Always On Monitoring (AOM).  Maybe a

Impressions of the OEM13c app from Oracle Cloud marketplace

Intrigued by the announcement that Oracle Enterprise Manager 13 (OEM13c) is available as an ‘app’, I decided to give it a go and try this app out. Before going into more detail, I must note that even though it’s called an app, it doesn’t come close to the definition of an app as we know

Oracle licenses needed while monitoring your (non-)Oracle environment with OEM

With Oracle Enterprise Manager (OEM) you are able to monitor an Oracle environment as well as a non-Oracle environment, like Microsoft’s SQL Server. You are also able to exchange notifications between Oracle Enterprise Manager and e.g. Microsoft’s SCOM. How to monitor this heterogeneous environment. What licenses do you for monitoring? And.. do you need Oracle

The curious case of the blank plugin page in OEM13c

After an upgrade of Oracle Enterprise Manager from 12.1.0.5 to 13.2, I wanted to deploy  a new version of the plugin oracle.sysman.db. Downloaded the new version and got to the plugin-management page to apply the patch. But all I got was a blank page. Cost me quite a while to figure out what the –

Deploying Oracle OEM agents 13c on windows targets (2008 R2) while OMS is on Linux

Situation at customer’s site: OMS 13.2 on Oracle Linux, targets are Windows machines, and a bit ancient: Windows 2008 R2. How to deploy agents on those targets? Several methods are possible in theory. In this blog I’ll describe my efforts to determine what is really possible and what is efficient.

Relocating base directory Enterprise Manager’s central agent

After the upgrade of the 12c central agent to 13c, I noticed the new central agent’s home located under the wrong – old agent – directory: /u01/app/oracle/agent12c/agent_13.2.0.0.0. Must have done something wrong. How to correct this? Want to move the directory to /u01/app/oracle/agent13c/. A very short blog to describe the two steps.

Upgrade OEM 12.1.0.5 OMS to OEM13.2

Despite the potential of Oracle Management Cloud, I’m a fan of Oracle Enterprise Manager, with its small imperfections. So when noticing a 12c Oracle Enterprise Manager on Linux, and targets on Windows, I took the challenge of modernizing the customer’s environment a bit. And the starting point , 12.1.0.5 for OMS and 12.1.0.2 database as

Connecting Oracle Management Cloud with Oracle Enterprise Manager 13c

Let’s clear about this: Oracle Management Cloud (OMC) is NOT a replacement of Oracle Enterprise Manager Cloud Control (OEM CC) or even an equivalant. Rumours are that this will  be Oracle’s policy in a far away future, but in the meantime we focus on what they do best. OEM CC is a product for a

Connect Oracle Enterprise Manager 13 to Amazon’s Cloudwatch

Oracle Enterprise Manager 13C has been introduced as a ‘single pane of glass’. Managing and monitoring all the assets, in or out of the public cloud. But when creating an RDS- database instance in Amazon’s cloud, it is monitored by Cloudwatch, and it’s not possible to install a so-called Oracle Hybrid Cloud Agent to connect
