Doubst to install 11g RAC & ASM

[dbasl]

Hi everybody;

I need to install oracle 11G RAC with ASM (2 nodes), but I have some doubts.
First, In the past I installed oracle 9i on Windows NT, and Oracle 10g in Solaris 10, but these versions were not RAC, and not ASM.

Now I have an IMB server, with OS AIX 5.3, Oracle 10G, RAC (2 nodes) & ASM.

These are the databases in Oracle 10G RAC with ASM.

/opt/oracle/admin
$ ls -ltr
total 8
drwxr-x--- 7 oracle dba 256 Jul 06 2008 +ASM
drwx------ 10 oracle dba 256 Jul 09 2008 MASTABPD
drwx------ 10 oracle dba 256 Jul 09 2008 MASTAMPD
drwx------ 11 oracle dba 4096 Aug 26 2008 MASTALPD



This is the configuration for each:



GROUP_NAME SECTOR_SIZE BLOCK_SIZE ALLOCATION_UNIT_SIZE STATE TYPE TOTAL_MB USED_MB PCT_USED
------------------------------ ----------- ---------- -------------------- ----------- ------ ---------- ---------- ----------
DG_AM_ASM 512 4096 1048576 CONNECTED EXTERN 204800 73739 36.01
DG_AL_ASM 512 4096 1048576 MOUNTED EXTERN 153600 7257 4.72
DG_AB_ASM 512 4096 1048576 MOUNTED EXTERN 179200 52666 29.39



What I is supposed to do, is to remove physically
MASTABPD and MASTAMPD. This database (MASTALPD) remain in 10G RAC with ASM.

Then, I got to install Oracle 11g RAC with ASM on the same server for a new database to replace these: MASTABPD and MASTAMPD.

I was viewing this document http://download.oracle.com/docs/cd/E...e17222/toc.htm, but I realized that I'm not going to upgrade
I want to do is a new installation of Oracle 11g RAC with ASM.

My questions are, once I remove these two databases, space (ALLOCATION_UNIT_SIZE) is released? I suppose, yes, but can I reuse that space if
I created a new DB in Oracle 11G with ASM?



For ASM, Do I have to do a new installation for ASM?
In this case, May I have the two installations (oracle 10G and 11G, with RAC and ASM at the same server?
Could this represent some conflict o problem?

Honestly, this will be my first installation of Oracle RAC with ASM, and I have a lot of doubts about to install the new version in the same server,
specifically I have my concern about ASM.

Thanks in advance for your help.

you can't use the same server if there is any instance currently running (ASM & DB). Also only one ASM instance should be there on each server.

In your case, you need to do fresh RAC installation on new servers.
