Step for Active/Passive RAC Patching (CPU Patch )

Hi
I know how to patch active /active configuration patching done in RAC.
I need to patch (CPU) for acitve/passive , how to i proceed ,is it the same ? i.e i can open passive node any how and the patch one by one .
Please suggest the step

Hi,
1) Will the 9.2.0.8 upgrade patching modified the SYSTEM tablespace and corresponding SYSTEM datafilesYes it will modify the SYSTEM tablespace and corresponding datafiles.
If I upgrade my active primary database first, will I be still able to upgrade the passive primary database without error laterYes u can upgrade passive primary database without error later
I shall be patching the database after failover the passive DB to become activecan u elaborate this further.
I suggest u to create a formal service request at MyoracoleSupport

RMAN for active passive 10g R2 RAC

Hi,
I am having 10g R2 Active-Passive RAC setup.
in this environment,If I am taking the backup using RMAN,
how can I handle the failover?
In active-active instance, if channel allocated to one node is failed, backup will be completed from channel allocated to other node.
how can i handle the failover in active-passive RMAN backup??/

What was the reason you went for active/passive RAC setup ?
--> this is requirement.
I thought cluster could achieve the same thing.
1) How can we achive active/passive setup by using cluster?
2) In RAC active/passive configuration and Cluster setup, which one is good option?
3) Any URLs on this topic
Thanks in Advance....

Active passive RAC configuration

hi,
how can I change the active-active RAC database to active-passive RAC database?
1) Is it enough to change active_instance_count=1?
2) Is there any change required in client side tnsnames.ora file?
I want to install two databases, db1 is active in node1 and passive in node2.
And db2 is active in node2 and passive in node1.
3) For configuration of this, which method is best?
current client side tnsnames.ora file as follows:
DBRAC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = gcappdev-vip)(PORT = 1523))
(ADDRESS = (PROTOCOL = TCP)(HOST = gcwebdev-vip)(PORT = 1523))
(LOAD_BALANCE = yes)
(FAILOVER=ON)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = DBRAC)
(FAILOVER_MODE = (TYPE=SELECT)(METHOD=BASIC))
)

When you mean passive.. do you want the database to be down or not usable?
If you are on 10g.. then the best method to do this is to use Services. Have services enabled on both instances. however it will be preferred on one instance /node and available on the other.
With this, when instance one where to crash, the service will failover to instance 2 and will be immediately available.

Weblogic HA for Active-Passive Admin Server configuration

Hi,
We are trying to install Admin servers in Active passive mode in a single domain to manage single set of managed servers (for OAM component). The scenerio is that I have Admin Server + Managed Server on OAMHOST1 and OAMHOST2 both. I can start Admin server on OAMHOST1 and then manage both the managed servers on OAMHOST1 and OAMHOST2. Now in case my Admin Server on OAMHOST1 goes down, the requirement is that secondary Admin Server on OAMHOST2 should be started and use to manage the managed servers on OAMHOST1 and OAMHOST2. So i have stopped the admin server on OAMHOST1 and then tried to start the Admin Server on OAMHOST2 but its not starting up. It is simply throwing the error that port 7001 on OAMHOST1 is in use but i can clearly see that there is no service running on 7001 port on OAMHOST1 and ALSO why its trying to connect OAMHOST1:7001. As per oracle documentation this is feasible (this is mentioned in their HA guide) but they haven't mentioned any step to configure this or test this.
Please advise if anyone has any idea to implement this. Since OAM admin is deployed on Admin server, the HA is crucial for Admin Server unavailability.

Hi,
From your note, I think OAMHOST1 and OAMHOST2 are physical hostnames of the server. You need to create one virtual ip which will be listened from both the physical servers and change the listen address for admin server to this VIP. Please see below mentioned link. Also there is requirement of shared directory, for that you can refer to the enterprise deployment guide for identity management.

Active/Passive RAC setup in 11.2 Standard Edition?

For the ACTIVE/PASSIVE setup in 10g RAC, the ACTIVE_INSTANCE_COUNT parameter works very well. However, in 11.2 version this parameter is obsolete. I'm testing this on our Test RAC server with Oracle Standard Edition 11.2.0.1. What are the other ways possible for an ACTIVE/PASSIVE cluster in Oracle 11.2? Has anybody gone through this before? I know that Oracle Enterprise Edition supports RAC One Node, but I've Standard Edition & moreover, I'm planning to have 2 databases on this cluster with 1 database being Active/Passive & the other being Passive/Active on the 2 nodes.
Appreciate any quick help!! Thanks.

Hi user1701261,
One option to divert traffic to specific node could be setting 11g Services in active , passive mode.
srvctl add service -d DB01 -s DB01_SRV -r "db011" -a "db012, db013"
Where
-d <db_unique_name> Unique name for the database
-s <service> Service name
-r "<preferred_list>" Comma separated list of preferred instances
-a "<available_list>" Comma separated list of available instances
Session will switch to incase db011 instance goes down.
active_instance_count parameter is effective only for Two node cluster, whereas using this method you could get more flexibility.

Sequence Co-ordination in Active/Passive RAC

Hello folks,
if we are creating 2 node RAC in Oracle 11g... Sequence coordination will happen between the nodes when the next sequence number is requested; The question is if I create the 2 node RAC in Active/Passive mode(I m thinking to do this either using ACTIVE_INSTANCE_COUNT parameter as I have only 2 nodes or to use srvctl to set preferred and available instances), will the sequence co-ordination will still happen if I request a sequence number?
Can you also please point me to the details on what all co-ordination happens between the nodes (2-active) at run-time?
I'm talking about Sequence coordination as the upstream app is dependent on Ordering of the Sequence.
Thanks in advance.

Steps for cloning a RAC 10g database

I would like to clone our production RAC database into my development environment. Can anyone help me by providing the steps to follow? I could not find anything on Metalink. Thanks in advance for your help.

I did the same few days back you can get a lot of help from http://idevelopment.info/ go to RMAN 10g and then Duplicating a Database using RMAN - (UNIX / Linux)
however I would give some of the steps
1. Take a full database backup of your Database using RMAN and catalog database, make sure you include current controlfile.
2. Create a new pfile from the original database pfile or spfile as the case may be.
3. comment out all RAC specific parameters such taht you can use the new pfile to start the database in single instance mode.
4. create a new sid for the new database and start the database in nomount mode using the edited pfile.
5. now connect to RMAN using your present database as target the new database as auxiliary and catalog database.
6. execute the duplicate database command.
7. You may need to do dbfilename convert if your directory structure is not same as of the original database, this is true for ASM too.
8. After the RMAN session ends control file should have been restored at the specified location in the edited pfile.
===
in case OMF is being used
9. shutdown the database (it can be in shutdown mode already).
10. Check the name of the controlfile and provide the name in the pfile.
====
11. start the database in single instance mode it should start.
12. now shutdown the database and uncomment the RAC specifiv parametors, please chek entries of REMOTE LISTENER etc.
13. register the database and instances with the CRS using srvctl
14. start the database with srvctl

Steps for data guard RAC primary RAC standby

Hi,
I have some doubt in configuring data guard for rac DR to rac primary.
1) In RAC DR, physical standby will be in RAC before starting data guard for RAC Primary , right?.
2) While configuring RAC DR , should one node be down in standby?.
3) After creating the auxiliary database in standby, i mean restoring the rman backup from staging directory in DR,
Shall we have to register the services(database,instance,asm,etc..) to CRS(OCR)?. If yes ,Why?.
4) After DR configure over , Shall i shut/down one node?. Should all the nodes in DR be in up , while applying logs to
standby ?.
If anybody have made the setup and have the prepared document , requesting you to share with me.
Thank you very much,
Sunand

Hi Sunand,
Please follow the following My Oracle Support (MOS) Document ID:
MAA - Creating a RAC Physical Standby for a RAC Primary [ID 380449.1]
For further details, see the referred documents in previous post. Try practicing on VMWare because it will give you the flexibility for creating snapshots to save your work. Please see the answers for your question below:
Q1. In RAC DR, physical standby will be in RAC before starting data guard for RAC Primary , right?.
Answer: Yes, this is recommend but not mandatory. You can add a second node later on.
Q2. While configuring RAC DR , should one node be down in standby?
Answer: Yes, there are some database configuration commands that should be run in exclusive mode. You can start the remaining instance(s) after DB creation. Do not forget to set CLUSTER_DATABASE parameter to TRUE. Also, all instances except one should be close while performing switchover/failover.
Q3. After creating the auxiliary database in standby, i mean restoring the rman backup from staging directory in DR, Shall we have to register the services(database,instance,asm,etc..) to CRS(OCR)?. If yes ,Why?
Answer: Yes, this is recommended for RAC configuration to take advantage of high availability services.
Q4. After DR configure over , Shall i shut/down one node?. Should all the nodes in DR be in up , while applying logs to
standby ?
Answer: You can start up all the instances after DR creation. In this case if your one node goes down log apply services will continue to apply changes in DR.
Hope, this helps to clear your questions.

Shahid

Anyone is using Active-Passive in BPEL environment??

RAC Active/Active VS Active/Passive 11g Configuration

Thanks in advance.
I appreciate your experience with implementing RAC in an Active/Active VS Active/Passive Configuration of 11g RAC.
Much of my experience has been with Active/Active to take full advantage of performance capability of both nodes (2 node cluster). As such, I don't see the advantages of Active/Passive RAC configuration.

The benefit is that you can save on licensing costs while gaining availability

Active Passive Vs Active Active

Hi All,
How much more effort it requires to failover or get up and ready with passive node, if Active Passive strategy is followed rather than Active Active just for saving on licenses.
Note : High availability is not a concern.
thanks,

Be clear what the policy means. RAC is normally considered an ACTIVE/ACTIVE solution since all nodes in RAC are actively processing. In an ACTIVE/PASSIVE setup by contrast one or more nodes are actively processing whilst others are standing by ready to take over the workload in the event of failure of the primary. Physical Standby, Failsafe and non-oracle clusters are often Active/Passive. You may also check if the policy comes from a sqlserver centric view of the world where you split the sqlserver databases between different nodes, so that although for any given sql database the solution is active passive, you don't 'waste' the resources of some nodes just waiting to take over, but rather run other databases on them.
Your description of ACTIVE/ACTIVE seems to rather correspond to a Stretch Cluster http://www.oracle.com/technology/deploy/availability/pdf/1126_Ray_WP.pdf has a good overview of what this means. I'd be surprised if the policy was really to put all databases on just about the most expensive hardware and software solution available, but I'm used to surprises in the world of corporate policies.

Any white papers or best practice document references would be great. I'd hate to do this just case of some policy.
Thanks

SOA Suite - Active/Passive HA

Dear All,
Need your guidance in configuring Oracle SOA suite with ESB to make it highly available (Active / Passive) . Have gone through one document but its only showing Active/Active configuration.
Is there any step by step doc for this.
Regards,

Thanks for update Taylor.I'm following from below URL:
http://download.oracle.com/docs/cd/B31017_01/core.1013/b28941/toc.htm
We need to install SOA suite with ESB,but the mentioned document doesnt give any scenerio for Active/Passive configuration for SOA.
I want to know how we'll distribute the software components on each node/shared storage for an Active/Passive topology, so in case of node failure , other node can take over.Currently we've installed following on a single node.
1- OC4J and J2EE in one home
2- SOA and ESB in second home
Any help will be highly appreciated.
