An extract of my Oracle related opinions. My experiences with ocrmirror, voting disks and stretched clusters. If you are about to migrate to Oracle RAC, there is an important thing to know about the OCRmirror. As far as I know, this is documented nowhere in any Oracle doc. This post talks about the failover properties of the OCRmirror. The following is the traditional thinking path of the higher ICT management:. The first problem however is: where do we put the storage? Wrong again. You need to have ...

An extract of my Oracle related opinions. Oracle VM and multiple local disks. Jun 9, 2008. For my Oracle VM test environment I have a server available with multiple internal disks of different size and speed. So I was wondering if it is possible to have all these disks used together for my virtual machines in Oracle VM. With this in mind I can install Oracle VM on my first disk and end up with 4 partitions on /dev/sda:. Root@nithog ovs]# mkfs.ocfs2 /dev/sdb1 mkfs.ocfs2 1.2.7 Filesystem la...From the mome...

An extract of my Oracle related opinions. Dec 7, 2007. Recently I described the use of Oracle Streams. To do an Oracle upgrade. It allows to create a new empty database of a higher version, and then use streams replication to keep it in sync with the old one. The final migration then consists of stopping the activity on the old database, make sure it is all replicated on the new, and then connect all clients to the new. Now it is just a question of generating some dynamic sql, concatenating all output of...

An extract of my Oracle related opinions. The ultimate story about OCR, OCRMIRROR and 2 storage boxes – Chapter 5. Scenario 5: Loss of ocrmirror from non-ocr-master – reloaded. This is a follow-up of chapter 4. In this final scenario, we do the same thing as in scenario 4. I.e. while crs is running on both nodes, we hide the ocrmirror from the non-ocr-master node, which is node 2 now. So node 1 is the master, we hide ocrmirror from node 2 and we verify on node 2:. And now it gets interesting…. We canR...
