Real Application Clusters :: How To Completely Shutdown The Entire Crs Stack In All Nodes

Nov 11, 2013

Grid version: 11.2.0.4Platform : OEL 6.4 

To shutdown the entire crs stack, I ran crsctl stop cluster -all from one node. After the command execution,  the below mentioned processes were still running on all nodes.   

[root@intsmdp01 ~]# ps -ef | grep d.binroot     38562 33228  0 19:12 pts/2    00:00:00 grep d.binroot     80820     1  0 Nov09 ?        00:20:56 /crs/product/11.2.0/bin/ohasd.bin rebootgrid     81448     1  0 Nov09 ?        00:01:22 /crs/product/11.2.0/bin/mdnsd.bingrid     81459     1  0 Nov09 ?        00:01:55 /crs/product/11.2.0/bin/gpnpd.bingrid     81473     1  0 Nov09 ?        00:17:26 /crs/product/11.2.0/bin/gipcd.binroot     81484     1 20 Nov09 ?        09:10:27 /crs/product/11.2.0/bin/osysmond.bin  

So , I had to manually run crsctl stop crs on all nodes. 

[root@intsmdp01 ~]# /crs/product/11.2.0/bin/crsctl stop crsCRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'intsmdp01'CRS-2673: Attempting to stop 'ora.crf' on 'intsmdp01'CRS-2673: Attempting to stop 'ora.drivers.acfs' on 'intsmdp01'CRS-2673: Attempting to stop 'ora.mdnsd' on 'intsmdp01'CRS-2677: Stop of 'ora.crf' on 'intsmdp01' succeededCRS-2673: Attempting to stop 'ora.gipcd' on 'intsmdp01'CRS-2677: Stop of 'ora.mdnsd' on 'intsmdp01' succeededCRS-2677: Stop of 'ora.drivers.acfs' on 'intsmdp01' succeededCRS-2677: Stop of 'ora.gipcd' on 'intsmdp01' succeededCRS-2673: Attempting to stop 'ora.gpnpd' on 'intsmdp01'CRS-2677: Stop of 'ora.gpnpd' on 'intsmdp01' succeededCRS-2793: Shutdown of Oracle High Availability Services-managed resources on 'intsmdp01' has completedCRS-4133: Oracle High Availability Services has been stopped.[root@intsmdp01 ~]#  

Is there a way to bring down the entire crs stack in all the nodes in the cluster from one node ?

Real Application Clusters :: Removing 2 Nodes From A Cluster Of 4 Nodes?

Nov 6, 2012

[URL] I arrived at step 2 (Step 2: Delete Nodes from the Cluster) point 4 and 5.

I executed this correctly (on 2 nodes):

For a nonshared home:

To delete a node from a cluster:

./runInstaller -updateNodeList ORACLE_HOME=Oracle_home CLUSTER_NODES="" –local

Output:

[oracle@server03 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME CLUSTER_NODES="" -local
Starting Oracle Universal Installer...
Checking swap space: must be greater than 500 MB.   Actual 20127 MB    Passed
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /u01/app/oraInventory
'UpdateNodeList' was successful.then I executed:

To deinstall the Oracle home from the node you are deleting, run the following command from the Oracle_home/oui/bin directory:

./runInstaller -deinstall -silent "REMOVE_HOMES={Oracle_home}" -local

Output:
[oracle@server03 bin]$ ./runInstaller -deinstall -silent "REMOVE_HOMES=$ORACLE_HOME" -local
Starting Oracle Universal Installer...

When I arrive to the point 5 I see one resource ora.DPCTTest.db ONLINE on one server (server02 or server03 that are the nodes I want to remove).
If I execute:

crs_relocate ora.db_name.db

I obtain:

Real Application Clusters :: Newly Installed 11gR2 - Inserted Rows Completely Gone When Restart Cluster

Jan 2, 2013

I have recently setup a 2 node Rac on oracle linux 5.4 with oracel 11gR2, the installation went smoothly and all the cluster resources are up and running however the data is not syncing across the nodes, when I create a table it shows up on the other node but when I insert rows into the tables they don't show up on the other node and when I restart the cluster the inserted rows are completely gone even from the node where I inserted them.

Real Application Clusters :: How Sessions Failover To Surviving Nodes

Sep 6, 2012

I want to apply patch for the 3 node rac database. I am going to use rolling upgrade, one node at a time. For this i need to stop all the instances or any processes running out of $ORACLE_HOME. I will use srvctl stop home command. My concern is:

1) with the srvctl stop home command how the instances shutdowns, either shutdown immediate or shutdown abort.
2) if applications are connected to the shutdown node, will the sessions fail over to surviving nodes?
3) If it is shutdown abort, how session failover?how about long running queries ? will they also fail-over?

Dec 27, 2012

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.

Grid Version:11.2.0.3OS : RHEL 5.8  I have succesfully installed cluster (GI) and installed RDBMS software on my 2-Node RAC . But, I don't want to use dbca to create the database due to some custom requirements. Instead , I want to run CREATE DATABASE command manually to create the RAC DB. Once the DB is created in one node, what are the steps I need to do to make this DB a RAC DB?

Real Application Clusters :: Information On Oracle 11g R2 (11.2.x) For RAC

Dec 11, 2012

1. RACcheck - RAC Configuration Audit Tool - RACcheck 2.1.6

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>]

3. NFS options for 11.2.0.2 RMAN disk backups on Linux 64-bit

4. In RAC environment from 11.2 onwards Backup Or Snapshot controlfile needs to be in shared location

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';

Real Application Clusters :: Deployment On Websphere?

Jan 7, 2013

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.

Real Application Clusters :: Number Of Local Disks

Jan 20, 2013

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…?

Real Application Clusters :: Possible To Have Three Undo Tablespaces For 2 Node

Oct 12, 2012

Version: 11.2.0.2/RHEL 5.4

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';

TABLESPACE_NAME                STATUS
------------------------------ ---------
UNDOTBS1                       ONLINE
UNDOTBS2                       ONLINE

Real Application Clusters :: 2 Node Instances On AIX - Row Lock

Jan 24, 2013

I 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..

Real Application Clusters :: Database Not Starting Up - Permission Error
