I have two node RAC on a test server. I have installed database software but it failed with an error that OEM could not be installed. Now I need installing Enterprise manager.

I was under the impression that you need only one UNDO Tablespace for each instance. But , for our 2-node RAC, I can see three Undo tablespaces.
SQL> select tablespace_name,status from dba_tablespaces where CONTENTS = 'UNDO';

Unable to start the crs in one node, totally it's four node rac and Database version - 10gR2?
View 2 Replies View RelatedI am wokring on oracle 10.2.0.4 rac 2 node instances on AIX. We have one table having multiple rows defilning jobs will be done by users ...the functionality is that ..when even one user will pick on row (job) , one update statement will issue and it will update status column to 1 which menas job is allocated , this means now this should not allocate to any other user ..
but we are facing issue that once any user will pick that job , in application log files we can see that row gets lock and updates the status to 1 . but then also users connecting to other or some time same instance will get that job...means multiple users can pick same job .. even after already picked by another user ..
Is this can be issue with rac configuration ... like whenever one user updates a row ..it will be in cache of one instance and when another user trys to again update 2nd instance does not have that information and allows user connected to that instance to pick that job..like delay in block transfer or cache fusion..
is this can be issue with rac or it is purely application issue..

In our 2-node RAC , Node1 was hung for a while. So, I wanted to restart that Instance. But I had some 50 services running in Instance 1(Preferred Instance) which has to relocated before I bounce the instance.
Question 1.
Instead of using srvctl relocate for each service, Is there any way to quickly relocate all services to the Node2 (Available Instance) ?
Question2.
When a service is relocated , are DMLs running from sessions using that service be 'moved' to the available instance ? Or, is it just the SELECTs that can be failed over ?
if multiple databases on one 2 nodes RAC is supported ? Explain me the inconvenient to have multiple databases on RAC ?

I am trying to design a database consolidation high-availability cluster for Oracle 11g R2 64-bit Enterprise Edition (X86-64) on Oracle Linux 6.x UEK, using Oracle 11.2.0.3 (the latest as of Aug 2012).
We don't need RAC Multi-Node now or in foreseeable future because none of the databases we run break the capacity of a single node. Likewise, we don't need to use Oracle VM to virtualise the database instances.
We plan to use SGA and PGA memory management to run multiple instances on same hardware operating on a single Linux 64-bit O/S image.Does it sound ok so far?
Two or three of 4-socket, 40-core Intel 64-bit servers with 512GB of RAM each (relatively cheap at today's HW commodity prices) will be sufficient to run all Oracle databases we have on Linux 64-bit.So the two HA options that I know of are:
(1) use Oracle Clusterware/Grid/ASM to provide for instance failover
(2) use Oracle RAC One Node on top of Clusterware/Grid/ASM
As I understand it RAC One Node is significantly more expensive than the "free" Oracle Clusterware/ASM/Grid (since we own Oracle 11.2.0.3 Enterprise Licences already). So why should my employer pay for RAC One Node licence given they already own Single Instance Fail-Over and Restart protection from Clusterware/Grid/ASM ?
I also read that Data Guard 11.2 may not be supported with RAC One Node on 11.2? True? Will same Data Guard 11.2 work with a Single-Instance Failover running on Clusterware/Grid/ASM ?
-Who is running RAC One Node? Why?
-Who is running Single Instance Failover with Clusterware? Why?
-Who is using Data Guard with either of the above?

This is a two node Standard Edition cluster.
The node crashes upon restart of clusterware after following the instructions from note:751343.1 (RAC Support for RDS Over Infiniband) to enable RDS. The cluster is running fine using ipoib for the cluster_interconnect.
1) As the ORACLE_HOME/GI_HOME owner, stop all resources (database, listener, ASM etc) that's running from the home. When stopping database, use NORMAL or IMMEDIATE option.
2) As root, if relinking 11gR2 Grid Infrastructure (GI) home, unlock GI home: GI_HOME/crs/install/rootcrs.pl -unlock
3) As the ORACLE_HOME/GI_HOME owner, go to ORACLE_HOME/GI_HOME and cd to rdbms/lib
4) As the ORACLE_HOME/GI_HOME owner, issue "make -f ins_rdbms.mk ipc_rds ioracle"
5) As root, if relinking 11gR2 Grid Infrastructure (GI) home, lock GI home: GI_HOME/crs/install/rootcrs.pl -patch

I have a 2 node RAC environment (11.2.0.3) where each node has there own local Grid_home and RDBMS_home.
I am installing a Rolling Bundle Patch with OPatch in this environment. The installation document says that "The order of patching in RAC install is GRID_HOME, then RDBMS_HOME" so i did the following.
1. stopped all oracle related services on node1
2. set oracle_home=<Grid_home>
3. applied the opatch
4. opatch succeeded on node1 and it says "The node 'NODE2' will be patched next... Is the node ready for patching?
1. Should i shutdown the oracle services in Node2 and continue to patch the Grid_home ? If yes then the DB will be completely down for user access. This defeats the purpose of rolling mode which says there is no downtime.
2. Should i patch the RDBMS_home on node1 , start all the oracle services on node1 , stop the oracle services on node2 and then resume the opatch on node1 which is waiting to patch the Grid_home on node2 ?
We are using oracle 11.2.0.3.0 with 3 node rac. Earlier 3 scan vip and 3scan listener running on each node.But we found recently node1 running using 2vip and 2scanlistener and in node2 1vip and 1scanlisteners were running.but no longer running scan vip or scan listener in node 3. If i decided to reloacate the scan vip/Scan_listener to node3 from ndoe 1 using below command,does it cause any impact on my transcation?
$ srvctl relocate scan -i 2 -n node03
$ srvctl relocate scan_LISTENER -i 2 -n node03
find the below details
$ bash

I m trying to make ORACLE RAC 10gr2 on two nodes with openfiler , with ocfs and asm.but i didn't have clusterware 10.2 software to install because oracle has removed software to download, that's why i install clusterware 11.2 . after installation clusterware 11.2 i check status and output is below on both nodes.
[oracle@linux2 bin]$ ./crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
but when i try to install oracle 10gr2 software and when i reach to configure asm disks it says "in order to use AUTOMATIC STORAGE MANAGEMENT the oracle cluster synchronization service (CSS) must be up and running. and says to run "/u01/app/oracle/product/10.2.0/db_1/bin/ localconfig reset* as root user.. I run it and it give no error.
is there any alarm in moving alert logs generated in the grid infrastructure. The alert log in the grid log directory has grown around 2gb .Our CRS version 11.2.02. on linux. Also pls, Sample script for automating the same.

2. In the service add command syntax using the srvctl command, there is a new option that can be used with the srvctl add service command which is [-l <primary, physical-standby, logical_standby>], this option allows the service to be able to start up only when the service role matches the database role that is saved in the OCR.
We can now add a service to a database in the OCR using the following command:
srvctl add service -d <db_unique_name>
-s <service_name>
[-l <primary, physical_standby, logical_standby>]

1. Check the snapshot controlfile location:
RMAN> show snapshot controlfile name;
2. Configure the snapshot controlfile to a shared disk:
RMAN> CONFIGURE SNAPSHOT CONTROLFILE NAME TO '<shared_disk>/snapcf_<DBNAME>.f';
Or in case of ASM use
RMAN> CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+<DiskGroup>/snapcf_<DBNAME>.f';
I have an java application deployed on websphere that is using Oracle. Datasource are created in websphere using URL like this:
jdbc:oracle:thin:@DBSERVER_NAME:1521:DB_NAME
Now, that we plan to move move to oracle rac, I learnt that we need to make change to datasource like this:
jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)
(HOST=DBSERVER1_NAME)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)
(HOST=DBSERVER2_NAME)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME
=DATABASE_SERVICENAME)))
would that be enough, or I need to make other changes as well from application perspective.
Another thing is that application deployment is done through ant scripts, which at the moment copies some data on /tmp/.. folder on db server and then run db scripts. These scripts make some ddl changes and some record updates. Now with rac implementation, these scripts will be run on one of the rac node(instances), so do I need to run these ddl scripts/record updates scripts on other node in oracle rac or oracle rac would take care of this automatically.
We are in preparation for the purchase of equipment for two- node Oracle10g RAC (on Windows Server 2008) and I need to configure the disks on servers. We have an existing EMC VNX5500 storage and SAN 8Gb switches.
My question is with how many disks to configure servers?Originally we planned four SSD discs (two in RAID 1 for OS and two in RAID 1 for locally Oracle home) for each node/server, and everything else on storage disks (Shared Disks Storage).
Whether it is necessary to have more local disks and for what? Where should be redologs files, archivelogs files, backup files…
Whether it is better server to be configured with six SSD disks:
- two in RAID 1 for OS,
- four in RAID 10 (or RAID 1) for locally Oracle home, archivelogs files, or something else…?
My client asked me to "apply the newest patch" on his RAC 10.2.0.5 environment on Windows.
I've downloaded 10.2.0.5 Patch 20 (the newest version).
My question is: Should i apply it using OPatch to both: ORACLE_HOME and CRS_HOME? or only in ORACLE_HOME? What with 10.2.0.5.2 CRS Patch? Should i apply earlier CPU patches?
