Rman config on 10g rac
hi,
i am using oracle 10g rac on aix , i want to configure rman to take complete backup . i want to use catalog and my database in on noarchive mode.
so please guide me steps to configure rman.
regards
read oracle online RMAN documentation for full info and for short info i.e. step by step read the following short notes

How can i shutdown the database (not instances) from RMAN? when i say shutdown immediate, it is shutting down the instance, but not the whole database and when i use startup mount, it complain that the database is already in open state.
You cannot do this inside RMAN, because RMAN always connects (and can only connect) to a specific instance. That's the same behaviour as for SQLPLUS. Use utility SRVCTL or Enterprise Manager to start/stop all instances.

RMAN-06012: channel: c1 not allocatedHi all I have the same problem. We have a 2 node rac with ASM. The archives goes to ASM. I would like to backup the archives from ASM to a filesystem. But i was given a filesystem that is only mounted on one node and it is not accessbile to the other node. When i run the following rman command i get the error on one of the channel that connect to node 2.
My question:
Can i use on channel that is connecting to node1 to backup all the archivelogs generated by node1 and node2 aswell since both the nodes have access to archive logs.
Please assist.

I am using VMware WorkStation 5

I can see my disks from both machines. Open the "Computer Management" dialog (Start > All Programs > Administrative Tools > Computer Management
I use Windows XP SP2 as the host operating system
Any suggestion?

MEXMANYou know its not certified?
My first thought when I read the subject of this thread, and before reading what you posted, is that you've either done no research on RAC or didn't understand what you've read.
You can create a RAC cluster using any operating system certified by Oracle.
But the operating system is the least important part of creating a cluster. The questions you need to be able to address are:
1. What is your solution to created shared storage?
2. What is your solution to create the cache fusion interconnect and VIPs?
If you don't have an answer to these questions you can not build a RAC cluster. -
Oracle database not starting up in oracle 10g RAC
Hi!
Recently I came across one problem with one node oracle 10g RAC.When the Oracle database is started,while opening it is giving ORA-03113:End of file on communication channel error.When I saw the the alert trace file and other trace files I found Disk group is exhausted error and it is not able to create .dbf files.Actually it is not a production server and I gave archive log destination in SAN.Even the spfile(content of init_database.ora) is in SAN..
I tried Asmcmd utility to delete the archive log files.As the oracle is not available I am not able to asmcmd prompt.
How to change the destination of archive log and to remove the old archive log files(as it is a testing environment we can remove) from SAN?Please let me know.
Thanks & Regards

On VMware there's a known issue with Oracle databases on a Windows client not starting up properly all the time and a manual startup using oradim -start -sid <whatever> is required to get it fully running. Hmmm, doing it several time, and never seen such issue. Which "known issue" and by who are you talking about ?
I created a brand new Oracle VM Windows 2003 32-bit server, installed the Oracle drivers for paravirtualization, and whammo, the problem is still hereI'm sure, you miss something somewhere in the config. Right now, you're on supported configuration, you could either raise a SR to the support, or get help from your peer on Oracle Database General forum.
Ah, but it's not a Windows issue. On a non-VM Windows box the database starts just fine all the time. Again, this is a known issue acknowledged by Oracle on the VMware side, I'm just surprised it exists on the Oracle VM side.Again, give more details about this "known issue". Never heard about that, eventhough I've been around for years.
I was afraid you were going to ask that. I'll have to search for it again, but I think you can do the same as well....Well, I doubt you could find a Metalink note about Oracle on VMWare. So far, Oracle has always refused to support database on OS virtualized on VMWare (or any VM software other than Oracle VM). Based on that, you could be sure, your "known issue" is not an issue on Oracle VM.
If you want more help, again, give more details about your issue.

What could be the disadvantage of the "AUTO_SPACE_ADVISOR_JOB" in 10g RAC?
Hi, all.
The database is 2 node RAC database on 32 bit windows 2003 EE SP1.
What could be the pros and "CONS" of the "AUTO_SPACE_ADVISOR_JOB" job
in 10g RAC?
It is one of advisor, and thus I think it is not required.
What could be the disadvantage of AUTO_SPACE_ADVISOR_JOB
in terms of PERFORMANCE in 2 node RAC environment?
The 2 node RAC database seems to be experiencing performance degrade
due to default jobs on installation such as AUTO_SPACE_ADVISOR_JOB and
GATHER_STATS_JOB.
I am looking forwared to hearing your experience and advice.
Thanks and Regards.Dear Justin.
Thanks for your reply.
1) What is the magnitude of the waits you're seeing? Over what time frame?
--> I found the above wait events in the top 5 wait event section from AWR report.
The AWR snapshot time frame is one hour.
--> On a regular basis(maybe, one or two week), the database hangs, causing a number of library cache related wait events and gc related wait event.
2) If the system is hanging and not doing a log switch, have you debugged that process? I'd be hard-pressed to imagine how library cache events would be related to this sort of thing. I would tend to suspect a hardware/ RAC install/ RAC config issue.
--> I applogize for insufficient information. I took "system state dump" and "hang analyze" at the time of database hang.
--> It is hard for me to understand the system dump file. I reported those files to Oracle Support, but no answer was returned now.
--> As you said, it may be caused by different issues. I will try to investigate other factors.
3) Why do you "guess that when gather_database_stats tries to get statistics about AWR snapshot objects, it causes a number of library cache invalidation and dictionary cache reload between two nodes?"
--> I investigated AWR reports during the period of database hang. I found the above wait events with gather_database_stats in common. That is all why I suspect "gather_database_stats" job.
Specifically regarding the statistics gathering job, is your application is doing something unusual that forces the default statistics job to gather statistics regularly on a substantial fraction of your tables forcing your application to re-parse a substantial fraction of its SQL? Do you have an alternate method for gathering statistics that is going to generate less load and/or invalidate fewer SQL statements? Is your application reusing SQL (i.e. using bind variables)?
--> Currently, we have not deployed all part of an application. At this point, the data is about 10 Mega. The application is using bind variables, but I also could see high number of sql version count. I am inspecting why.
--> I am considering gathering statistics manually (only application schema, not all database objects)
4) What makes you believe that the AWR snapshot process is causing problems?
--> I applogize for insufficient explanation. I mean the problems occur when "gather_database_stats" job takes statistics of "AWR snapshot data",
because application data is very very small, only 10 Mega and 28 tables.
Currently, we have deployed only 1 % of the entire application.
● This is the first time I manage a RAC database. I think a RAC database is something different from a single database.
I do not think the same problem could occur in a single database.
Thanks for detailed explanation and advice.

10g RAC on Solaris 10 containers - Question on Approach
Hi All
To introduce a little, I am trying to set-up 10g RAC (active-active) on Solaris 10 Containers. For the disaster recovery site, I was considering an option for storage replication across datacenters. As I look at the situation where the database could be highly transactional, I wanted to go for this option hoping I might be better able to recover db on dr site if a failure happens and also alleviate some load from the prod servers. In this regard I have a set of questions for which if you could share your experiences, thoughts .. I am sure will help my preperation.
1 Is Oracle Supported on Solaris 10 containers? I believe it is not supported and ofcourse am getting into the certification matrix for this with oracle. Anyways, any work around tried out by anyone ?
2 Which product is better in terms of performance while co-existing and co-functioning with Oracle? Sun Cluster!!! Vertas Cluster!!! any other? I am unable to link to any recommendations from Oracle and hence trying to understand the generic or say standard approach to this.
3 I understand on Prod site, Oracle remains active-active on two node cluster while I will mirror my SAN between Prod site and DR site on a timely basis, while DB is up and running. This mirroring has to be only an asynchronous mirroring for some limitations. I am unsure about my recoverability if we need to switch over to DR. Will I be able to recover the Database to a point when my last mirroring has been completed successfully when I say the mirroring happened while the Prod db is up and running (hot backup type on disk level). Until now I used a cold backup for Storage replication and I was sure to bring it up there. This hot backup kind of attempt is raising unrest and questions about the abilities.. :-(
4 I also have come across a term called federated databases? Is it similar to what I am trying to achieve here? Storage level replocation across data centres?
I know it takes some time to get to the end of it and finally implement it, but your inputs will certainly help me get things straight before I hit this first click. Thanks for all your inputs, advices, suggestions. :-)
Regards!
SaratAccording to Oracle "Both Oracle 9i R2 and 10g R2 databases have been certified to run in a Solaris Container."
There are references here :- http://forums.sun.com/thread.jspa?threadID=5397695
"Oracle databases (RAC and non-RAC) have been certified to run in a global Solaris 10 Container"
What storage are you using ? (filesystem, ASM ?) Personally I prefer ASM now, but it does depend on the storage platform and backup strategy.
What backup infrastructure do you have ? RMAN backup directly to tape is better than file copy.
For DR standby purposes I would use Dataguard instead of disk mirroring / storage replication. It is much more flexible (e.g can switch direction of replication, do incremental backups from the standby etc).
I would use CRS instead of VCS. CRS is built for the job, and integrates with netca, dbca, etc for service management, and also integrates with Dataguard Broker for standby switchover. -
Regarding Services in Oracle 10g RAC
Hi All,
We are having Oracle 10g RAC (10.2) on Linux machines. We don't have any services configured failover. This can be visible from srvctl config database -d, as nothing related services information is displayed.
I even checked failover_type and Failover_method from GV$session and for all it's showing None. We have only default database service (same as database name).
My question is:
Can I modify/configure this default service as failover/loadbalance enabled using srvctl? If so, please let me know.
PS: I can't provide any output here as our client network doesn't permit copying.
Regads,

RMAN backup in ORACLE RAC database
Hi there,
We are using RMAN backup strategy for taking backups from one node(eg.node1).Database is RAC database, version 9.2.3. and OS is Solaris 5.10.
this is the configuration which we use, as follows:
Connecting to Prod.Database using catalog database.
rman catalog=rman/rman@CATDB target=sys/oracle@PRODDB(node 2).
RMAN> show all;
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 30;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/rmanback/_%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 5;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/rmanback/CMWPROD_%s.bak';
CONFIGURE CHANNEL 2 DEVICE TYPE DISK CONNECT 'SYS/oracle@PRODDB(node2)';
CONFIGURE MAXSETSIZE TO 7 G;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/oracle/9.2.3/dbs/snapcf_CMWPROD1.f';
As the above config shows RMAN is connecting to PROD DB (node 2). But we need to take backups (datafiles and as well as archive logs) from two nodes (i.e from node 1 and as well as node 2).
Is there any possibility for taking backups from two nodes?
Thanks,

RMAN configuration in ORACLE RAC database
Khurram -
Seeking a solid reccomendation concerning 10g RAC implementation.
I need a solid recommendation regarding what hardware I should use for my planned Oracle 10g RAC environment.
Currently, I am looking for both node and SAN recommendations.
I also created a list of 11 questions that I need to have answered.
Here is how this will be configured:
3 Node Oracle 10g RAC
Each Node will consist of:
32Gb of RAM (minimum)
Windows 2003 64-bit Enterprise (corporate standard, but I can go with Windows 2008 if I have a valid justification)
74Gb RAID 1 (minimum)
Dual 10Gb Ethernet NICs
The SAN will consist of:
750Gb-3Tb dedicated to Oracle
10Gb Ethernet NICs
Here are some of my general questions:
1.) Are there any benchmarks or case studies that you are aware of that might help in the decision process regarding hardware?
2.) Where should my backups reside (SAN or elsewhere)?
3.) What margin should be added for SAN provisioning and waste (even if thin provisioning is implemented)?
4.) My CIO has decided to direct me to go with 10GbE copper instead of fiber channel, what unplanned hiccups can I expect?
5.) What are the caveats of running dual redundant SAN systems?
6.) We are currently using DELL hardware for all other systems, however I do have the freedom to change the vendor for this particular project if I can state a valid business justification. Any other vendors out there that make a better SAN or Node solution than Dell/EMC?
7.) How much local storage do I need on each node?
8.) Can I utilize 1 node to run ETL during production hours without drastically affecting database performance?
9.) Regarding the maintenance of this setup, are their any particular classes or training you would recommend? I am a seasoned Oracle DBA, but could use any specific training on the specifics of RAC and/or general performance.
10.) Are there specific advantages in Oracle 11g RAC vs. 10g that would be worth the cost of upgrading our 1000+ 10g user licenses?
11.) Are there any studies on the performance advantages/disadvantages of running Oracle 10g on Windows vs. Solaris (or any Unix)?
I will consider all input of high value, so please let me know what you would recommend.
Thank you for your time.please find answers that i know for some questions.
1.) Are there any benchmarks or case studies that you are aware of that might help in the decision process regarding hardware?
2.) Where should my backups reside (SAN or elsewhere)?
=> what is the backup method you will be using? certainly recommend RMAN (in addition to OS backups that you are planning to use) for block recovery, should there a block corruption.
i would keep some copies on the SAN local and mirror to DR site too.
3.) What margin should be added for SAN provisioning and waste (even if thin provisioning is implemented)?
=> do not suggest thin provisioning for production.
how big the volumes are going to be? reason for asking the Q is, if the volumes are going to be in TB, percentages can be lower. please plan for 2 years atleast.
4.) My CIO has decided to direct me to go with 10GbE copper instead of fiber channel, what unplanned hiccups can I expect?
5.) What are the caveats of running dual redundant SAN systems?
6.) We are currently using DELL hardware for all other systems, however I do have the freedom to change the vendor for this particular project if I can state a valid business justification. Any other vendors out there that make a better SAN or Node solution than Dell/EMC?
7.) How much local storage do I need on each node?
=> have beetween 75GB to 100GB. hope you are going to have only ORACLE RDBMS and CRS software in here.
please make sure that you rotate your listener logs and alert logs and regular removal of old .trc files older than certain number of days old.
8.) Can I utilize 1 node to run ETL during production hours without drastically affecting database performance?
=> node usage will help from CPU standpoint only. what about the disk writes it is going to perform to the data files?
9.) Regarding the maintenance of this setup, are their any particular classes or training you would recommend? I am a seasoned Oracle DBA, but could use any specific training on the specifics of RAC and/or general performance.
=> attend a 5 day course from Oracle. install RAC on own and play with it.
10.) Are there specific advantages in Oracle 11g RAC vs. 10g that would be worth the cost of upgrading our 1000+ 10g user licenses?
=> did not compare, though installed 11g.
11.) Are there any studies on the performance advantages/disadvantages of running Oracle 10g on Windows vs. Solaris (or any Unix)?
=> running on windows? please do not. used on linux a lot. pretty stable and solid. recommend to go with 10.2.0.4 or higher.
hope the above will help. -

10g RAC Node down Enterprise Manager
Hello
We have a 2 node Oracle 10g RAC Rel2 Linux setup. Enterprise Manager was first stalled on Node1 and we access it using http://node1:5500/em.
This node has a hardware failure and is out of commision at the moment. When I try to connect to http://node2.5500/em it does not work.
I see the dbconsole process is running onthe node2.
How can I use the Enterprise Manager if the node1 is down?
ThanksCan you try deconfig and config again on node 2?
emctl stop dbconsol
emca -deconfig dbcontrol

Oracle database 10g RAC and ASm installation
Hi all,
I want to ask to everybody something about Oracle 10g RAC and ASm configuration. We plan to migrate to Oracle 10g from 9i, and we will begin configuring oracle but we have to decide which configuration are the best.
Our materials are bellow:
Hardware: RP 3440 (HP)
OS : HPUX 11i Ver 1
Storage: EVA 4000 (eva disk group)
The problem is:
Our supplier recommand us to use HP serviguard + HP serviceguard extension for RAC+ RAc and Raw device as configuration.
But we want to use Oracekl Clusterware + RAC + ASM
My question is if anybody know what is the best configuration, we want to use ASm.
Can we use HP serviguard and ASM.
Some documentations or link explain oracle RAC and ASM configuration will be appreciate.
Thanks for your help.
Regards.

Hi,
Anybody did 11i/10g RAC Failover test. How to do the test and what steps involved. What is expected when one node down?
my config
web, admin, form - appsnode1
concurrent / db (rac1) - dbnode1
concurrent /db (rac2) - dbnode2
Thanks for your help.
RegardsYou can check the below
1. VIP Failover - VIP should failover when node gets rebooted.
2. When one of the node is down you should still be able to logon to applications.
3. Since you have only one node and do not use PCP you CM processes will die.Make sure you start them.
4.Once you bring the node back , test your load balancing is happening fine across both the db nodes.
Let me know if this is helpful/correct and if you need more information.
Regards
