Tips, tricks, (and maybe a few rants) so more DBAs become bulletproof!

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 […]

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 […]

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 […]

Dealing with Wi-Fi Problems the DBA Kevlar Way

As much as KSCOPE 14 fixed any and all Low-T levels, it couldn’t do anything for our the WiFi problems we were experiencing back in May. I’ve been a telecommuter for almost 4 straight years now and was quite frustrated when our WiFi service became dismal back then. We called Comcast service and worked through […]

Weblogic Start Failure: Empty Initial Replica

This post is to address a failed Weblogic start in EM12c.  The fix is performed on a Windows host, but the fix can easily be for any EM12c environment that experiences this issue.  In the below instructions, just replace the %OMS_BASE% for Windows Env Var to $OMS_BASE for Linux/Unix. Issue:  OMS Fails to Start and […]

Monitoring a Microsoft OS Failover Cluster

I know, I know-  none of you are using Microsoft Windows.  This is why I get so many questions on this topic and why there is so much interest in a white paper that no one thought I needed to write.  Well, while that pesky ol’ white paper is in review, I’m going to go […]

Using ASH Analytics to View Blocked Sessions

When concurrency is the crippling factor in a database performance issue, often I’m told that viewing blocked sessions in Enterprise Manager is difficult.  The query behind, along with flash image generation in any Enterprise Manager can take considerable time to render and no matter how valuable the view is, the wait is something DBAs just […]

AWR Warehouse, Status

So the AWR Warehouse patches are out, but documentation has not officially caught up to it yet, so as we appreciate your patience.  I thought I would post about what I went over in my webinar last week when I had the wonderful opportunity to speak to the ODTUG members on this feature that everyone […]
