EM12c Release 4, Health Overview

As part of the projects I work on at Oracle, it’s often ensuring that those customers that wish to deploy Enterprise Manager, (EM12c) to large environments, have the correct settings and are tuned to offer the best performance from the Oracle Management repository database, weblogic and up to the console URL’s accessed by users.  This means that these large environments often receive recommendations from our experts  that differ from what EM12c comes “out of (more...)

Metric Thresholds and the Power to Adapt

Metric thresholds have come a long way since I started working with OEM 10g.  I remember how frustrating it could be if an ETL load impacted the metric values that had to be set for a given IO or CPU load for a database when during business hours, a much lower value would be preferable.  Having to explain to the business why a notification wasn’t sent during the day due to the threshold (more...)

SIOUG and HROUG Fall Conferences, 2014!

I’ve just returned from my honeymoon in Venice with the wonderful Tim Gorman, but before we enjoyed our week in this picturesque city, we spent a week doing joint keynotes and two sessions each on our own tech topics at these two incredible conferences in neighboring countries.

SIOUG, (Slovenia Oracle User Group) in Ljubljana, Slovenia held their 2014 conference Oct. 13th-14th at the Plaza Hotel.  Tim and I did a joint keynote, “Assumptions, the (more...)

Abstract Review Tips

Yes, this is for my RMOUG abstract reviewers, but it may help other conferences and user groups, too.  We have some incredible content at RMOUG, (Rocky Mtn. Oracle User Group) Training Days conference and its all due to a very highly controlled, thought out process that has evolved over time to ensure that we have an abstract selection process that is as fair as possible and offers new speakers opportunities as well.

I’m going to (more...)

Building a Great Conference Agenda

We are deep into RMOUG’s abstract submissions and reviews, preparing for the following:

  • Oct. 2nd-  Close of Abstract Submissions
  • Oct. 6th-  Close of Abstract Reviews
  • Oct. 10th-  Schedule up for 2015 Training Days

With this weighing so heavily on my mind, I felt it might be a good time to put down on paper why I’m so proud of how RMOUG does it’s reviews and why this conference has such a great lineup.  This (more...)

How to Configure EM12c to NOT Use Load Balancers

This may not come up very often, but for some reason, an administrator might have to reconfigure an EM12c environment to NOT use load balancers.

This could be due to:

1.  Hardware Issue on the Load Balancers
2.  Mis-configured Load Balancers
3.  Re-allocation of Load Balancer hardware for other purposes.

Whatever the reason may be, I noted that the instructions to set up the load balancers are easy to find, but not (more...)

Oracle Open World Schedule

I will be in San Francisco a little early this year and as I’m not longer an ACE Director, it’s to attend the IOUC, (International Oracle User Conference) at Redwood Shores on Sept. 25th and 26th.  I’ll be representing RMOUG for the two day event that has representatives from user groups from all over the world.  Our lovely host, Mary Lou Dopart and her team, will ensure we have another great (more...)

EM12c and Windows OS Failover Cluster- Keep it Simple

This is going to be a “KISS”, (Keep it Simple, Silly) post.  I was offered a second Windows cluster to test on when my original one was required for QA.  It was a gracious offer, but I also found out why a cluster should be kept simple and this cluster was anything but simple.  Many times, issues are created and we’ll never see them coming until we go through the pain and (more...)

Renaming an Oracle Apache Target in EM12c

When installing Enterprise Manager 12c, the host value can come from a number of places for different applications/tiers.  For most, it comes from the environment variable $ORACLE_HOSTNAME, (for Windows Servers, %ORACLE_HOSTNAME%).

The OHS1 target, aka Oracle Apache in the middle tier of the EM12c environment pulls it’s value from the etc/hosts file, (for Unix as well as Windows) and so it is vulnerable with a virtual host name or host name change occurs.  (more...)
