Oracle 11g RAC on NFS…

As a follow-on from my 10g RAC on NFS article, I thought it would be nice to have an 11g RAC on NFS article. The process is very similar, with a couple of exceptions:

  • The Virtual IP Configuration Assistant (vipca) runs in silent mode without any problems now. Under 10g, you had to use a “real” public IP address for this to work. Under 11g it now works with private IPs like “192.168.x.x” etc.
  • Oracle 11g includes a Direct NFS Client for “optimized” Oracle over NFS performance. I don’t have the relevant kit to do a performance comparison, so I don’t know if it’s worth it or not. If someone has some figures for this I would be interested to hear them.

Oracle 10g RAC using NFS…

I’ve mentioned it before, but I really like Kevin Closson‘s blog. For some time he’s been evangelizing about Oracle RAC over NFS, so I thought I would give it a go to see what it’s all about and here is the result.

Oracle 10g RAC On Linux Using NFS

I was only using two machines, and I didn’t have access to a NAS that supported NFS, so I was forced to use one of the RAC nodes as my NFS server. I know it’s a dumb idea, but it proves the technology.

If you are just playing about, the nice thing about this solution is you don’t need to worry about “real” shared storage. I prefer it to the VMware approach because you don’t need a single server with loads of memory to fake two virtual machines and the shared storage. Finding two poor machines is always easier than 1 good one. 🙂

Oracle 10gR2 on Fedora 7…

I had a quick go at this installation and it worked OK. I had to load a bunch of FC6 packages to get Oracle to install, link and run properly. It looks like lots of the “compat_*” packages have been removed from Fedora 7, which is a problem as Oracle 10g needs them. The “libaio” package is no longer present. I’m sure the functionality is there somewhere, but I couldn’t get the listener to work without loading the old package. Also, the “libXP” package is necessary to get the installer to run. It has also been removed, along with some deprecated X11 packages that were present in FC6.

I’m sure the cleanup makes sense going forward, and 10g is getting a little old in Fedora timescales, but I wonder how many other applications will be broken by this.

Of course, I’m no Linux expert, so maybe I’ve missed something and these extra packages are not really needed.

Oracle Database 10g for Windows Vista…

I’ve been on holiday for a few days, so this latest release passed me by.

PS. Please don’t ask me for help installing Oracle on Vista. I’ve never done it and I don’t plan on trying. Instead I would advise you use VMware Server or Virtual Box to run Oracle on Oracle Enterprise Linux. A much neater solution in my opinion.

Red Hat Enterprise Linux 5 (RHEL5)…

I’ve been having a play with the beta 2 of Red Hat Enterprise Linux 5 (RHEL5).

Having seen the various Fedora Core versions released since RHEL4, I knew what to expect from RHEL5, but somehow I hoped for a bit more. If just feels like RHEL4 with a different theme.

I can see why Microsoft always add a bunch fancy new gizmos to every Windows release. They need something to differentiate the product, regardless of its usefulness, and people like me fall for it every time… 🙂

Oracle 10g Release 2 on Solaris 10…

Well, it was released and I have VMware, so I thought I would give it a go. I’ve not used Solaris for a while so I hit a few stumbling blocks, but I got the installation to work in the end:

Oracle Database 10g Release 2 (10.2.0.2) Installation On Solaris 10 (x86)

Given the choice I would use Linux… 🙂

FC6 Draft Articles…

I’ve written a couple of draft installation articles for DB10g R2 and AS10g R3 on Fedora Core 6 (Test 2).

I’ll revisit the articles once the final version of FC6 is released. I’m hoping the warning at the start of the articles prevents a repeat of the FC5 incident. 🙂

As expected, FC6 has diverged even further from RHEL4. There are a bunch of packages that either don’t exist or are deprecated. The software seems to work OK, but I’m not sure how many problems are waiting in the wings. It will be interesting to see how Oracle and RHEL5 get on together, especially where RAC is concerned.

Cheers

Hallelujah…

OK. It’s been a long wait, but 10g Release 2 is now available for Tru64. There is still no sign of the 10.1.0.4 or 10.1.0.5 patches, but you can’t have everything. Of course, the big issue now is, how can I persuade the company to go for a migration???
This is definitely the last release for Tru64, so we’ve got to move to it, but who knows when?

Rules Manager (tip of the iceberg)…

I’ve been having a play with the Rules Manager introduced in Oracle 10g Release 2. There is quite a bit of functionality in there, so my article is just a “tip of the iceberg” type of thing.

This would have come in extremely handy in two previous jobs, both of which required quite complex state-event engines. It certainly would have made the decision processes a little more flexible, provided the performance was acceptable.

Cheers
