adding datafile to a RAC database
Hi Friends,
We have an application running on Oracle 9i RAC RS/6000 AIX, this was configured/done (outsourced) by an Oracle Consultant. Lately we got an error of "unable to exted index on tablespace ...".
My question is...is an RAC DB cannot make its tablspace autoextend?
Can u help me pls how to add a data file for RAC installed database?
If i have 2 nodes of this (Real Apps Cluster)parallel server...can i add to either one of the nodes only without downtime?
Thank you very much for your unfailing support

that kinda stuff is the same for RAC as for non RAC, from any node just set the datafile to autoextend or add a new datafile as normal

Wow...what a speedy reply dear friend Dave....thanks u so much...you are heaven sent.
Im just confused because before we have also 8i OPS which is now migrated to 9i RAC done by same Oracle Consultant. And I can see his
scripts in adding datafiles before...format raw device...varyon vg to
both nodes...and add datafile.
Do i still need to allot a raw device? or RAC now uses filesystem type
of storage. Im really afraid i will mess up this expensive set-up database.
Thanks again to all of you my dear friends

I guess, you are using RAW file system for your RAC environment. You should have enough space in your RAW file system to extend your datafiles. You may use lsvg, lslv commands to get the information about your RAW volumes.

a raw device?

it can use a raw device or a clustered file system (like ocfs)
-
Hi friend...hmmn i really dont know which type was used...is there a
way to check it?
Thanks again
-
select file_name from dba_data_files, post what that says and should be able to see what format it is in so we can decide if you are using raw or filesystems
-
Thanks dave....
The file_names are quite similar,
like 'u01/oradata/PROD/index01.dbf',
but when you go to this dir, i get
$ cd /u01/oradata/PROD
ls -l
index01.dbf -> lvora021
he used ln -s command here.
should it be on both nodes?
I guess raw device was used. I just dont know how to
account/inventory all those used and unused raw devices since u cant see them. I also remember that u have to used the character raw dev
agains block raw dev.
Can u pls give me links to docs on how to create/configure
raw devices/shared disk for RAC set-up?
Thanks a lot
