Change unknown SYSMAN password on #EM12c

When I normally start work on a new EM 12c environment, I would request to have a userid created; however, I don’t have a userid in this environment and I need access EM 12c as SYSMAN.  Without knowing the password for SYSMAN, how can I access the EM 12c interface?  The short answer is that I can change the SYSMAN password from the OS where EM 12c is running.

Adding additional agents to OEM12c

One question I get asked a lot is “how can I add additional agent software to OEM 12c”?  The answer is pretty easy; just download and apply to the software library.  Now what does that mean?  In this post, I’ll explain how to download additional agents for later deployments to other platforms.

After logging into OEM 12c, go to the Setup -> Extensibility -> Self Update (Image 1).

Using #DB12c PDB as a Repository for #EM12c…. Not so fast!

Last year, I wrote a post on how to setup Oracle Enterprise Manger 12c (12.1.0.3) with Oracle Database 12c (12.1.0.1) and what you could expect.  At the time the configuration was not supported by Oracle and I only did it to see if it could be done.  If you would like to read that post it can be found here.

This past May (2014), I attended the Oracle Customer (more...)

Integrated Application Heartbeat for Oracle GoldenGate

Over the last two weeks I’ve been working on a heartbeat monitoring solution for a client.  This is not the normal heartbeat solution provided by Oracle as described in note 1299679.1; yet very similar.  The approach that I configured is similar to a traditional heartbeat setup but uses the same extract and replicats already being used by the database/application.  For simplicity reasons, I like to call this approach an Integrated Application Heartbeat.

OGG-00212, what a frustrating error.

Normally, I don’t mind errors when I’m working with Oracle GoldenGate (OGG); I actually like getting errors, keeps me on my toes and gives me something to solve.  Clients on the other hand do not like errors…LOL.  Solving errors in OGG is normally pretty straight forward with the help of the documentation.  Although today I can almost disagree with the docs.

Today, as I’ve been working on implementing a solution with OGG 11.1.x (more...)

#GoldenGate Bound Recovery

Every once in awhile when I restart an extract, I see entries in the report file that reference “Bounded Recovery”.  What exactly is “Bounded Recovery”?

First, keep in mind that “Bounded Recovery” is only for Oracle databases!

Second, according to the documentation, “Bounded Recovery” is a component of the general extract checkpointing facility.  This component of the extract guarantees an efficient recovery after an extract stops for any reason, no matter how many uncommitted transactions (more...)

Macros and parameter passing macros with #goldengate

Replicating data can be a time consuming process to setup.  Fortunately, Oracle GoldenGate provide a few tools to help ease the  complexity of setup.  One of these tools is the “macro”.  Macros are used to simplify and automate the work associated with setting up and replicating data.  So what exactly is a macro?  Oracle defines a macro as:

A macro is a built-in automation tool that enables you to call a stored set of processing (more...)

Understanding and using tokens in Oracle #GoldenGate

Recently, I’ve been doing some work with a client where tokens need to be used.  It came to my attention that the basic usage of tokens is misunderstood.  Let’s see if I can clear this up a bit for people reading.

In Oracle GoldenGate, tokens are a way to capture and store data in the header of the trail file (more info on trail headers here).  Once a token has been defined, captured and (more...)

Speedy #em12c template export

Wither you use a single OEM and migrating to a new OEM or have multiple OEMs, the need to move templates between environments will arise.  I had this exact problem come up recently at a customer site between an OEM 11g and OEM 12c.  In order to move the templates, I needed to export the multiple monitoring templates using EMCLI.  The command that I used to do individual exports was the following:


./emcli export_template -name="<template  (more...)

Upgrade Oracle Enterprise Manager 12c (12.1.0.2) to 12.1.0.3

In order to upgrade out OEM environment from 12.1.0.2 to 12.1.0.3 we need to download the latest version of OEM from either http://otn.oracle.com or from http://edelivery.oracle.com. Once we have the files needed to upgrade, we need to stage them in (more…)
