We have an Oracle 9i (9.2.0.7) two-node RAC database running on Solaris 5.8. Recently we have switched our production database from no archive log mode to archive log. We changed the parameter CLUSTER_DATABASE=FALSE on one of the instances before converting and reverted back.why this parameter needs to be changed to false?
View 2 RepliesI have oracle 10g up and running on Solaris 10, from windows I would like to connect to sql plus through windows authentication, for that I have already made sure that remote_auth = true and have created user in oracle with OPS$. But still I cannot connect.
I have the same setup but with oracle on windows server, the os authentication from windows clients works just fine.
does oracle 10g on solaris 10 supports windows os authentication?

I have 2 node 11gR2 RAC running on AIX 6.1, after I shutdown the database and restart crs using crsctl start crs, ASM instance comes back up but not the database and I had to start the database using srvctl, isn't that the database should come up when I start the crs?

View 5 Replies View RelatedI've configured a replication environment with Oracle 11g (Multi-master synchronous replication). Apparently it works fine, when replication is started any change in a table that belongs in a node is replicated in the rest of the nodes.
One of the tests I'm making is the following: Try to see what happens if one of the nodes drops. Meanwhile one of the nodes is no avalaible, any modification in an available node is not allowed (as I expected). I'm trying to see if the database service can be available meanwhile a node is missing, although the replications is not running.
What I've experienced is replication cannot be suspended until the the node was down is restarted.
Is this the usual behaviour or can I set any parameters to avoid this? In other words, is it possible the database service is running meanwhile one of the nodes is down? The application I'm working on needs this type of replication, buy also needs the service is running always?
What can I do to make possible the service is running even when a node falls?
when running the root.sh on second node the following error occured

I am part of a upgradation and migration proj where an Oracle 9i db on a HP-UX OS is going to be upgraded and migrated as 10g db on a solaris OS environment.I am from the application team(Data warehouse team) and we are yet to allocate a specific DBA for taking care of this activity.
We are still in the requirements stage...different requirements and challenges that should be taken care and would occur in the roadmap of this project from a DBA perspective.All your inputs would be very valuable to me.
We are planning to migate Oracle database from Linux 10gR2 (non-ASM) to Solaris (ASM) and then Oracle upgrade that database from 10gR2 to 11gR2 on Solaris.
View 4 Replies View RelatedWe've been battling with very slow performance for some time. Herewith a detail description of the problem:
Solaris-11/ZFS/Oracle problem
We purchased Oracle T4-2 servers, and are experiencing some weird performance problems.
Hardware:
T4-2
2 x 600GB HDD per server
128GB memory per server
2 x dual port QLE2562 FO HBAs
IBM V7000 StorWyse data array
2 x CISCO MDS 9148 fibre optic fabric switches
Software:
Solaris 11.1
MPXIO
Solaris 10 branded local zones
ORACLE 10g Enterprise edition
Project for the oracle user:
user.oracle:100::oracle::process.max-file-descriptor=(basic,8192,deny);process.max-stack-size=(priv,32768,deny);project.max-shm-memory=(priv,21474836480,deny)
We received the first server and wanted to migrate our APPB application system and Oracle 10g Standard Edition database from our SUN T5240 to the T4-2.
T4-2 setup � Disk 0:
Global zone: Solaris 11.1 ( ZFS - whole disk for the root pool)
Local zones: On the Solaris 11 environment we built two branded Solaris 10 zones using an Oracle template provided on the Oracle website - solaris-10u11-sparc.bin.
Our complete database resides on the IBM data array, in UFS LUNs.The UFS LUNs were mounted onto ZFS mount-points in the root partition (/), and then LOFS mounted into the zones.
We started with the Solaris 11.1 environment.
1)After a day or two the performance of the database starts deteriorating rapidly. We then stop the database and reboot the machine. After the reboot the performance level is restored.
2)Another huge deterioration in performance happens when we unmount the V7000 LUNs, and reboot to the alternate Solaris, and re-mount the LUNs.
3)What further compounds the issue is that when we start another the database in the second zone, we see another huge performance degradation.
4)We have logged a call with ORACLE. They requested us to gather information which was analysed by them. They did not find anything wrong with the way ORACLE was installed and the setup of the instances.
On Disk 1 we did a Solaris 10 8/11 (Update 10) installation, which we patched with the April 2013 CPU patchset. In this Solaris 10 global zone we built two native Solaris 10 local zones. The Oracle 10g databases were built in the zones (same configurations settings) not in the global zone, onto UFS LUNs. The database in its entirety lives on the IBM V7000 data array. This works fine.
We then received our next T4-2 server.Loaded it again with Solaris 11.1, and upgraded to ORACLE 12c SE Release 12.1.0.1.0 - 64bit12xxx seeing that Oracle 10 is not certified on Solaris 11. To keep things simple, we built two small databases in the ZFS root pool. The complete system now resides on one disk no UFS LUNs to consider, no Fibre Optic fabric, no CISCO switches, no IBM data array, BUT we get the same problem. The system will run for some time and then slow down drastically. Starting the second database slows the system down abnormally.

I believe, in a multiple RAC Physical Standby nodes only one node applies the archivelogs to the standby database. How you can find which node is the APPLY NODE using a SQL query?
I know you can veiw this information by querying the standby configuration using DGMGRL but how would you find out this information from a remote client using SQLPlus/PLSQL?

I would like get more details about single node RAC.. What is single Node RAC?..
1). just configure only one server instead of two node... same RAC installation.. cluster installation and shared disk configuration in single server itself.. in future we can add node to this ...
2). in 11gR2 having new feature Single Node RAC.. Multiple instances running on same node and configure using Cluster...
is there any advantage using single node rac(other than online upgrade to full RAC).

i'm trying to duplicate my RAC database with ASM and 2 nodes to a single node, non ASM with rman duplicate database for standby with active database on windows. The problem is i dont know how to remove RAC configuration when duplicating the database.
Here is the procedure:

- installed database software,
- configured listener and tnsnames,
- added instance service (oradim -new -sid STANDBY -intpwd PASSWORD -startmode M),
- configured initora (with only db_name = STANDBY)
- configured orapwd file
- startup nomount
on RAC node1:
rman target sys/PASSWORD@RAC
connected to target database
RMAN> connect auxiliary sys/password@STANDBY
connected to auxiliary database: STANDBY (not mounted)
now for the duplicate command:
RMAN> duplicate target database

We have to configure Dataguard for our 24x7 critical banking 2 Node RAC database(10.2.0.4). Before proceeding with the configuration we have to make sure what steps we should follow to have minimum or no downtime.
1) Document covering DG setup in RAC environment.
2) We have to perform switchover as well so need its steps too. Either the normal switchover steps would be used or have to stop/start rac services as well.
