There are many sites explaining how to install Oracle GI 12.2, however, there are some special tricks which can simplify GI installation. For once, when installing GI and then installing the huge PatchSet (which is usually around 1.4GB in size) – it takes time. A lot of time. A simple but not very well documented…
When installing Oracle RAC (or in its more modern name – GI) version 11.2.0.1 and above, you can use Oracle ASM DiskGroup as your CRS+Voting file location. It is fairly simple changing the disk membership in Oracle ASM DiskGroup, however, when you face some unknown bugs which prevent you from doing just that, or when you are required…
I wanted to write down a guide for RHCS on RHEL/Centos6 and XenServer. If you want to do that, you need to go through two major challenges which you will encounter. I want to save on the search and sum it all up together here. The first difficulty is the shared disk. In order to…
When using Ricci as the engine for ‘cman_tool version -r’ command, you will experience timeouts (and practically – you will be unable to use ricci to update the cluster configuration across the nodes) when the ricci user password contains XML-sensitive characters, like <>&, etc. As they say – FYI 🙂
This is a very nice project I have been working on. The hardware at hand – two servers, with a shared SAS bus containing several SAS disks. Since it’s a shared bus, no RAID solution would cut it, and as I don’t want to waste disks with ASM (“normal” redundancy meaning half the size…), I…
The concept of running a virtual machine, KVM-based, in this case, under RHCS is acceptable and reasonable. The interesting part is that the <vm/> directive replaces the <service/> directive and acts as a high-level directive for VMs. This allows for things which cannot be performed with regular ‘service’, such as live migration. There are probably…
