Full Version: new db - how to partition raw disks?
Oracle DBA Forums > Oracle > Oracle Forum

I am a new Oracle DBA that has been tasked with creating some single node databases for our programmers to connect to. I have never built a database, only upgraded. I will be using a Dell 610 with 10.2.0.4 software. I have been reading the install guides but cannot find a definitive answer for how to create the raw partitions. I have a SAN that I can utilize and my current db is set up with RAID 6 like so:

Disk 2 300 GB 1 Extended 300 GB and 5 logical, 100MB, 30 MB, 100 GB, 100 GB, 100 GB
Disk 3 100GB 1 Extended 100 GB and 3 logical 100 MB, 30 MB, 100 GB

Can anyone explain to me why the old DBA partitioned this way? I am not good with storage and know that I need to understand before I build new databases so I do not duplicate something that is wrong. I was reading articles that recommend SAME but would not know how to do that on the SAN.

I will be using data pump to export the database and import to the new server. I was looking at using transportable tablespaces to do this. Would you recommend that from the cluster to the standalone?

I was looking at buying the Oracle RAC pack. Will that help me if I am running Oracle on Windows? I have been Unix until now...

Thanks for any help or reading material you can provide!!

Hi Jamie,

No problem! Here is a template:

That's a GREAT question! Only the diosk vendor can tell you . . .

You can use whatever you want, but the standard for Oracle is SAME (RAID-10):

Oh, use ASM: Automated storage management:

Which one?

Rampant sells a RAC Pack (books) and Oracle Corporation sells a RAC pack for $40,000.00.

Too slow . . . Clone them instead:

It depends. If the surce database is shut down transportable tablespaces are fine, but if you can clone by simply copying the datafile, that's easy and faster . . .

In Sum,

- Your DELL is just a glorified personal computer, don't get too fancy.

- With only two disk platters, you are guaranteed to get I/O contention no matter what you do. Just stick with plain JFS files for now.

- If you get I/O bound, plan on adding RAM chips to the Dell servers. Make sure that they are 64-bit and that there is room for at least 64 gig of RAM chips, in case you need a large data buffer.

- Stick with UNIX, trust me, you DO NOT want to go with Oracle Windows!

- You don't need RAC unless that system has a downtime > $100,000 per minute

- For books, get the Easy Oracle Jumpstart pack:

If you want one of my experts to help you, call 800-766-1884 and you can get a DBA to walk you through it . . .

Good Luck!

Thank you so much for the input! I will look through everything and see where I am at biggrin.gif

I am only utilizing windows because that is how they have everything configured and they won't let me change it. I would much rather be back in Unix land smile.gif But they are very specific with requirements, RAC being one of them. Do you think I would be better off with the Jumpstart pack or RAC pack?

I will definitely look into your Oracle support/mentoring. I would love to have that but not sure if my company will pay for it. I just got told an hour ago that we have to move servers from one VLAN to another. I have a 2 node cluster that is on private ip/subnet so I am thinking we can configure the private VLAN the same and not have to make any changes to the database? I know Oracle does not support changing the ip or hostname so I am hoping that can be our workaround.

Again thank you very much!

Hi Jamie,

As you know, any Maroon can click buttons on a GUI, and UNIX is far more difficult, but infinitely mnore flexible.

Please read, I write this page just for you:

BTW, there is a new book just out: Linux for the Orackle DBA:

I wholeheartedly agree with you on the article. I know a lot of managers that think that Windows is better. I think in part because that is what they are comfortable with and in part because they are not technical and GUI's are pretty smile.gif

I ordered the Oracle Easy Pack so I am looking forward to getting to sit down with those.

Thanks for the forum and all the helpful articles! I have spent many hours so far reading through them smile.gif
