PREPARING OAS on standby node
Hello Everyone,
I have 2 HP-UX servers working in a ServiceGuard cluster. One node is DB node and other is OAS node. They are also standby nodes for each others function (during failure db package goes to oas server and vice versa).
With db it was easy for me, but how to prepare oas environment on db server?
the shared filesystems which will be moved with oas package contains logs from application and application's war files. Binaries are not shared.
Sholud I only copy the binaries from OAS and thats it ?
Regards
Radek
You should still be able to bring up the standby as read only. During managed recovery the database is in a mounted state and therefore can't be connected to via the listener.

Dataguard using ASM in primary node and FILESYSTEM in standby node
Hi There!
I need to configure a Dataguard, and my primary DB is working on ASM, the standby node is going to be using filesystems, so I want to know if there is a guide that I can follow in order to get this task successfully completed.
My operating system is Solaris 10, and the DB Release is 10.2.0.4. I want to know the best practices.
Also I want to remember some RMAN Restore and Recover techniques to have this configuration ready, up and running.
Thanks in Advance.
Paola
@>--->----setting this up isn't that different to setting up a single instance standby on ASM,
the MAA guide is here
http://www.oracle.com/technology/deploy/availability/pdf/MAA_WP_10g_RACPrimarySingleInstancePhysicalStandby.pdf
this details the configuration using ASM on both sides, if you want to use filesystem storage on the standby then the following parameters will need to be changed
*.db_file_name_convert='+DATA/CHICAGO/','+DATA/BOSTON/','+RECOVERY/CHICAGO','+RECOVERY/BOSTON'
*.log_file_name_convert='+DATA/CHICAGO/','+DATA/BOSTON/','+RECOVERY/CHICAGO','+RECOVERY/BOSTON'
to something like
*.db_file_name_convert='+DATA/CHICAGO/','/oradata/boston','+RECOVERY/CHICAGO','/recovery/boston'
*.log_file_name_convert='+DATA/CHICAGO/','/oradata/boston','+RECOVERY/CHICAGO','/recovery/boston'
alternativly you can set the DB_CREATE_FILE_DEST and DB_CREATE_ONLINE_LOG_DEST_n parameters and let oracle create OMF files for the dataguard instance.

Applying patches to physical standby node(Data Guard 10.2.0.3)
Hello,
I have a data guard 10.2.0.3 environment (1 primary and 1 physical standby on a separate node) on solaris 10 and i want to document the procedure in applying patches to this environment.
I saw the article in Metalink Note 278641.1 which describes the procedure in applying a patchset to both nodes. It looks like both nodes need to be down before applying the oracle patchset.
Can we not apply the patches on only the standby while the primary stays up and running? My guess is you can't if the patches are significant i.e. it changes versions of the oracle binaries. But i want to confirm this.
Also, if we are applying solaris patches, i.e. nothing related to Oracle, we should be able to just apply them to the standby while keeping the primary up and running right?
The following has worked so far but i wanted to find some documentation that confirms it's ok.
1. shutdown oracle on standby node.
2. apply solaris patches...
3. restart oracle on standby node and put in managed recovery mode.
Any comments are appreciated.
Thanks.Hi
Did you get an answer for your question yet? I have the same problem with one of our databases. Would be very nice, if you could tell me.

I 'd like to know regarding a method to separate a standby node from CE
Hi community
I have a question regarding a method to separate a standby node from CE.
I would like to know if it is possible to run the vary off command on standby node while active instance is working.
For example,
-shutdown standby instance on standby server.
-run vary off and exportvg command on standby node while active instance is working.
Version Info
-OS : AIX 6.1
-DBMS : Sybase CE 15.5 with 2Node
-Shared Volumn : DS8700 ( 4TB )
In this case, I would like to know if there is any side effect on Active instance.
Our CE version is ASE15.5 ESD5.3 on AIX.
Thanks in advance
Regards
Taiwoo KimTo make sure I understand, you have a two node ASE cluster....one of which is active, the second is idle. You want to detach (for some reason) the disks from the second node of the cluster.
From the cluster viewpoint, provided you shutdown the ASE instance on that node and don't run any cluster utilities on that node (e.g. sybcluster, quorumutil, etc.) - then whether the disks are attached or not is likely not going to be an issue. It would be no difference to the surviving node than if you shutdown the other node completely (host included).
What concerns me is that you obviously are planning something that affects that volume group - e.g. moving it to a new machine??? Swapping HW??? Updating OS volume management firmware??? If swapping HW, remember, the quorum has the list of participants in the cluster - so unless the new hardware hostname/ipaddr matches the old, you will need to modify the quorum entries (TechSupport can help with this) - although the better approach would be to build a new node of the cluster on the new HW (temporarily a 3 node cluster) and then remove the old node from the cluster. If updating OS firmware, just be careful that the patch doesn't cause problems with IO fencing by changing the SCSI PGR versions or something. -
Easy question, might be a complex answer.
We currently run 4 node RAC clusters (10gR2). 3 nodes are active and 1 is standby. When one of the 3 nodes fails, all the connections switch to the standby node. What we want to do is when the failed node returns to the cluster for that to be come the standby node for the cluster. Any ideas?

Edited by: user11992160 on Oct 5, 2009 12:59 PMHi buddy,
Only one doubt...
When You said:
We currently run 4 node RAC clusters (10gR2). 3 nodes are active and 1 is standby. When one of the 3 nodes fails, all the connections switch to the standby nodeYou mean, You have services preferred in 3 nodes and in one node they are available, right?
If Yes,
You have to relocate the service using srvctl. The command is:
srvctl relocate service -d <DB_NAME> -s <SERVICE_NAME> -i <OLD_INSTANCE_NAME> -t <NEW_INSTANCE_NAME>

Script for auto recovery of standby node - Simple dataguard
Hi.
I have set up several solutions with Oracle SE and simple dataguard on linux.
On physical standby, I have created a script which performs the recovery every 15 minuts:
source /u01/app/oracle/sb_scripts/.profile_websb
/u01/app/oracle/product/10.2.0/bin/sqlplus "/ as sysdba" <<EOFSQL
recover automatic standby database;
exit;
EOFSQL
However, I am trying to perform the same on a windows environment but struggles a bit with the script.
Initally I tried %ORACLE_HOME%\bin\sqlplus / as sysdba @c:\scripts\recover.sql
Where recover.sql has been:
recover automatic standby database;
exit;
and :
recover automatic standby database until cancel;
alter database recover cancel;
exit;
Neither of these exits the bat scripts but awaits user input on CANCEL after the last archived log has been added.
Anyone with a bright idea on how to solve this?
Thanks.

This script I use for windows (linked from my old site at http://www.niall.litchfield.dial.pipex.com/ ) uses
alter database recover automatic standby database until cancel;
alter database recover cancel;Note the extra alter database I'll admit I haven't run this personally in 2 or 3 years now.

Hi,
I have installed Oracle 10 App Server successfully on my machine with webtier, app tier, and database on a single node. I would like to request if someone can help me out for the steps installing Oracle10g AS on multinode.
i.e appl on one and database on other node.
Thanking you
regards,For that
Install DB
Look for Metadata Repository Create Assitant this will help you to create the Repository for the Infra
Then install infra and you have to point to this DB so it wont install the DB and install only the app.
Also if you want a midtier appserver in other box, you can point the installation to the repository in other server.

TAF Service OFFLINE on standby node
Hi,
We have created primary and secondary RAC. A TAF service which is ONLINE on primary is added to standby side and is enabled but it shows the OFFLINE status. Is this default behaviour. We can't start is using "srvctl start service" command. My understanding is since the DB is physical standby which is not open, this is the reason the service is OFF line. Once the standby switches to primary it can be brought up. Correct?You should still be able to bring up the standby as read only. During managed recovery the database is in a mounted state and therefore can't be connected to via the listener.

Requried Oracle10g Physical Garaguard doc ID?
Hi,
we are going to Implement the oracle 10gR2, physical dataguard with broker architecture.
We have Two nodes , one for Oracle R12 Application node and second is Oracle 10g R2 database.
And our requriement is to prepare the third standby node, we have decided that to configure physical standby database with both maximum protection mode and maximum availability mode.
So, Is there any latest metalink doc ID or anyone have an sample step-by-step Document?
Thanks in advance,

Logical and Physical Standby on same Node
Is it possible to have a logical and physical standby database for a primary database on the same node (i.e. primary on NodeA, logical and physical database of primary on NodeB)?
Will there be any conflicts with data guard broker with this configuration or any problems I may encounter?From a technical point of view this is possible. Your standby node should be powerful enough to handle 2 instances. For even higher availability 3 dedicated nodes would be better. When Node B is down, both physical and logical standby are also down.

Problem in Archive log sync with Passive Node to Standby
Hi,
I have configured Active-Passive Oracle Database using Fail Safe between Active and Passive Node. Also successfully configured Data Guard between Active Node to Standby Node.
Versions:
1. Oracle Database Version: Oracle 11g R2
2. Oracle Fail Safe: 3.4.2
3. OS: Windows Server 2008 R2
Problem:
Now after fail over the database to Passive node, to check whether the DR is functioning or not, archive logs are not transferring to Standby node. In the Passive Node aler log file error is showing:
"ORA-01031: insufficient privileges
PING[ARC2]: heartbeat failed to connect to standby órcldr´. Error is 1031
Could anyone please let me know the possible reason for this and the resolution.Hello;
I'm thinking password file. It needs to be the same copy on all instances.
Did you copy and rename it as needed?
And you need to restart using the correct copy of the password file too.
So a Standby for example must startup on the correct copy of the password file or you will still get the error.
Best Regards

OAS: Building a HA environment with OAS
Hi all,
we have tio scale up our OFM capacity asap. Because migration to WLS in a short time is not possible, we have to prepare OAS Cluster + SOA 10g environment. We are working at this moment in a single node environment.
I'd like to know about best practice for OAS-Cluster design and realization.
Best Reagrds,
Mohwe will use active/active 3 named instance FCI in primary site
name of instance are instance_a, instance_b and instance_c
how i will accomplish this in primary?
how i configure only one SQL in DR site for 3 named instane?
how i will configure AOHA on both primary and DR site?
I am not expert please help me step by step if possible with snap shot.
Hi ABDUL,
As Edwin’s post, build Windows Server Failover Cluster (WSFC) firstly, for more details, please review this
blog.
Secondly, build SQL Server Failover Cluster, you can follow the steps in this similar blog:
SQL 2012 Failover Cluster Build (Step by Step).
Thirdly, add SQL Server AlwaysOn Availability Groups to the existing SQL Server Failover Cluster Instance (FCI), please review this similar blog:
Adding SQL Server AlwaysOn Availability Groups to existing Failover Clusters.

Fail to ping standby . error = 3113 in trace files (oracle 9i)

The error I want to highlight is "FAIL TO PING STANDBY UMERCADO3, ERROR 3113"
I did this testings on the primary server:
- Unix ping to standby node , ok
- tnsping to standby database (tnsping umercado3), ok
Therefore I do not find the reason for this error. By this time I have defeered the transfer from the primary to standby.
Any advice is welcome.
Thanks!Suggestion: would attempt to make a sqlplus connection from the primary to the standby using the tns entry that you have configured for the log_archive_dest parameter. you need to connect to the standby as sys.
What happened:
I did a sqlplus connection ON THE PRIMARY DATABASE using the tns entry that is exactly the same used in log_archive_dest_2 parameter. Here is it:
SQL> conn sys/*********@UMERCADO3 as sysdba
Connected.
Therefore I do not think it is a problem in the standby password file.
Any suggestions? -
Query regarding standby database state when primary is down or un-reachable
Hi
I want to know if there is any reflection on the standby database states when it's primary is down or not reachable? I want to use this information from standby node to determine if I can programatically execute (dgmgrl) failover operation or not? This is considering that the broker configuration has no fast-startfailover and no observer enabled/configured.
Thanks,

YojanaYou don't have exactly such option,
But you have alternate for it. Whenever standby is unreachable to primary then from standby alert log file you can see informational messages as RFS: Possible network disconnect with primary database , So you can write a script to grep those contents and to mail alert, so that you can sense whether any issue with primary database.

Grid Control and Standby Database
I have a (single node) physical standby server for a two node RAC Primary.
I can view the standby server in OEM ( java tool).
How do I add the standby db in my Grid Control ( 10.2.0.4.0 )
regards,LilyThanks for the reply.
Yes I have grid agent running on the standby node. I have also installed 'yast rpms' and the grid control is able to see the host under the 'target' tab of grid control.
While trying to discover the standby database, the automatic target discover fails.
Then I did the 'manually add', and it complains 'failed to connect'.
I believe, this is mainly because the STANDBY database is in 'MOUNT' state and I am using 'dbsnmp' to connect ot the grid control ( my grid control is configured to register new database as 'dbsnmp').
