CELLDIAG user for Exadata

I was doing some tasks off from my task list and one of the things exachk highlighted was that we should create user CELLDIAG on cells. Beginning with Exadata Storage Server Software version 12.1.2.2.0, the storage server user “CELLDIAG” is created during deployment which allows access to diagnostics without using a more privileged user. The…

Exadata & metric_iorm.pl

Our case where to gather information was actually related to two disks going OFFLINE at the same time. As I wasn’t sure if this is normal Exadata behavior I went and created Service Request for this. This is what we saw one day: 4_1 2017-01-04T18:54:05+01:00 warning “Data hard disk entered confinement offline status. The LUN…

Automated sundiag.sh for Exadata nodes

We recently had to collect sundiag.sh output to one of our Service Requests and I followed note “Oracle Exadata Diagnostic Information required for Disk Failures and some other Hardware issues (Doc ID 761868.1)“. And while there isn’t too much of work involved I thought perhaps I could reduce few steps. Below is short script which creates…

Automated exachk

I was speaking in December at UKOUG Tech’16 and attended Andy Colvin‘s session on “5 Quick Tips for Exadata Administrators”.

Wouldn’t it be good to run it for example every…

Exadata, Oracle eBS and exachk

Nice feature which I wasn’t aware earlier is that when you run exachk for your Exadata it has eBS specific section as well. So not all content is related to Exadata or databases. There are million posts about exachk so I won’t go into details on it but exachk is as per Oracle: Oracle ORAchk and…

Installing Oracle VM 3.4.2 (Part 2)

On part 2 for OVM 3.4.2 I’ll show how to configure OVM up to running speed so you can create VM’s. It’s  again really straightforward and doesn’t  need much previous (or at all) knowledge. Networking As we use iSCSI for our storage I need to add our iSCSI networks to OVM and link them to…

Installing Oracle VM 3.4.2 (Part 1)

Moi! We currently use Oracle VM 3.3.3 quite heavily and look to improve our setup. So for that I decided to install latest Oracle VM 3.4.2. to see what improvements it brings. Oracle Virtualization blog has good summary on 3.4.2: https://blogs.oracle.com/virtualization/entry/oracle_vm_3_4_2 To install I had to download two files. One for OVM Manager and one…
