Regarding Heartbeat in RAC 11gR2

Hi,
This week and completed RAC 11gR2 installation on Linux environment successfully.
Now customer's NETWORK guy raised one more point related to heartbeat and requested us to change from single heartbeat to dual(may be multi) heartbeat. Can any body share me the links related to this? I am doing further cheks on this through MOS.
1) How to check what kind of heartbeat is being configured.
2) how to change to dual/Multi heart beat mode. etc.......
Thanks in-advance for your support.
Regards
DBA.

Starting from 11.2.0.2 there are new feature called High Availability Interconnect, which allows you to create up to 4 interconnects. In reality, even if you configure only 1 interconnect, all 4 will be created. Having several interconnects simplify the ip change if required somewhere in the future, along with loadbalancing and failover capabilities.

ASM pfile lost in Oracle RAC 11gr2

Hello Gurus,
I am new to Oracle RAC 11gr2 and facing some issues. our spfile/pfile for asm instance is lost and I am not able to startup the asm instance.
Environment is as below:
RAC 2 nodes
Oracle RAC 11gr2
Enterprise Linux Server release 5.5 (Carthage)
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/u01/app/oracle/product/11.2.0/db_1/dbs/init+ASM1.ora'
Is there any way to recover the spfile/pfile ?
Also getting following error while try to connect " sqlplus / as sysasm"
$ sqlplus / as sysasm

Hi,
Do we need to Set variable ORACLE_HOME properly (Grid Home) while starting RDBMS instance?
e.g ORACLE_HOME=/u01/app/11.2.0/grid*I recommend you set ORACLE_HOME properly for each Oracle Installation when you use SQLPLUS.
i.e: cat /etc/oratab
orcl:/u01/app/oracle/product/11.2.0/db_1
db10g:/u01/app/oracle/product/10.2.0/db_1
+ASM1:/u01/app/11.2.0/gridAlso you can startup/shutdown our database with SQLPLUS using ORACLE NET*, but it must be configured properly.
My recommendation <s>is always</s> use SRVCTL and CRSCTL to manage to your environment. Track all the process of initialization processes through the logs using ADRCI utility (only 11.1 or later).
When use SRVCTL or CRSCTL to manage I recomend you use (GRID HOME).

SQL>I give to you three options:
1° - Add more asmdisk on Diskgroup +FRA
2° - Make backup of all archivelog using RMAN and option delete input (i.e backup archivelog delete all input;)
3° - If this database is for TEST ONLY and you not need backup or recovery of then you can delete all archivelog using RMAN (i.e delete archivelog all;)
I recommend you create routine of backups of the database and archivelog to prevent this area becomes exhausted.
If you need the database in archivelog but it is only to test then create routine to delete archivelogs periodically.
If you dont need the database in archivelog, then just disable it.

Best Practice for monitoring RAC 11gR2

Hi,
I have RAC 11gR2+ASM on two nodes.
I would like to get your advice what are the most critical things i should monitor - Regarding RAC COMPONENCTS
Thanks

Hi,
here i am mentioning some basic monitoring
1)interconnect switch is working properly or not(private network)
2) check which instances are running on which nodes
3) check if ASM,listeners,nodeapps,gsd,vip..... are running or not.
Each instance carrying planned load (balanced?).
– Shared storage access is equal.
– Interconnect Load
-Latency
– High CPU usage - Oracle processes getting enough resources.?
Thanks

ORA-00354, ORA-00353 on RAC 11gR2

Hello All,
I have a database Oracle RAC 11gR2 on OEL linux 5.5 32bit.
When i am trying startup my database I am facing the below errors: this error is occuring on the startup of any node
ERROR at line 1:
ORA-00354: corrupt redo log block header
ORA-00353: log corruption near block 2651 change 1172351 time 10/12/2011

ORA-00312: online log 1 thread 1: '+DATA/orcl/onlinelog/group_1.261.761845161'It seems that my online redo log is corrupted. how can i solve that ?
knowing that my database is running in NOARCHIVELOG mode and i do not have any backup.
and why i am not able to start up any of the nodes? redo logs is not related to each node seperately ?
I tried: srvctl start instance -d orcl -i orcl1 or srvctl start instance -d orcl -i orcl2
but the same error, where is the High Availibilty in that case, the redo log file group_1 is for thread 1 only. SHould not be able to start Instance 2?
Regards,
Edited by: NB on Oct 13, 2011 5:12 PM

since my database is runing in NOARCHIVELOG mode and i have no backups and the current is logfile was the corrupted one and my database was not starting.
I solved that by ceating a pfile and adding the : allowresetlogs_corruption=TRUE

Steps to stop / start CRS & ASM in RAC 11gr2

Hello Gurus,
Environment is as below:
RAC 2 nodes
Oracle RAC 11gr2
Enterprise Linux Server release 5.5 (Carthage)
I am new to Oracle RAC 11gr2 and facing some issues while stop / start crs & asm.
We want to reboot both nodes and for that I have done following steps.
1. srvctl stop database -d <db name> -- from one node
Databse is down now.2. srvctl stop nodeapps -n <hostname> -- from both nodes
services are down now.3. Now I want to stop asm
$ export ORACLE_HOME=/u01/app/11.2.0/grid ( Grid Home)
$ srvctl stop asm - This is not stopping ASM instance.
4. crsctl stop crs -- this is also not working.
I would appreciate if you please give me full steps.
Thanks and Regards,

In 11gr2, gsd remains offline. When I had checked with metalink, they said that it is fine.
In 11gr2 you can stop all resouces as below
<CRS_HOME>/bin/crsctl stop has
or you can stop in the following sequence
stop or relocate service using srvctl
stop instnace using srvctl
stop asm using srvctl
stop nodeapps using srvctl
stop cluster resources as root - <CRS_HOME>/bin/crsctl stop has
To start
<CRS_HOME>/bin/crsctl start has - it should bring all resources automatically
verify the services status and start or relocate it back.

RAC 11GR2 + expdp/impdp

Hi all,
I have installed Rac 11gr2 on linux RedHat.
I have to migrate data from a 10.1 database to the 11.2 database.
Could you tell me which version of expdp and impdp should i use?
Thanks.

You use the 10g datapump expdp on the 10g DB (source) and the 11g impdp on the 11g DB (target).
Kind regards

Need to review RAC 11gR2 environment.

Hi,
Today my manager asked me to review a customer's RAC 11gR2 environment. and i need to take up this assignment next week. i going through couple of things in the net related to HEALTH checks. are there any inputs from your side on "Topics to cover"
I am trying to cover all aspects as much as possible.
Regards
DBA.

If you have to ask for help on these forums from complete strangers regarding your assignment, then you are doing yourself, the company you work for, and your customer a complete and inexcusable disservice. Pl tell your manager to give this assignment to a more qualified person - no personal offense intended.

How to migrate DB from single node 10gR2 to RAC 11gR2 on diff platform?

How to migrate DB from single node 10gR2 to RAC 11gR2 on different platform with possible minimum downtime? We have a situation of upgrade/migrate oracle 10gR2 single instance DB to 2-node RAC 11gR. The source OS is Solaris 10 on SPARC and the target OS is Linux (the target servers could be changed to Solaris 11 x86 if needed). What is the best solution on that?
Thanks,

Technically, can do the following for upgrading and migration?
1. Create 11gR2 oracle home on the same server and upgrade the database from 10gR2 to 11gR2 by running conversion (2 hour down time?)
2. Set up Heterogeneous Primary and Physical Standbys by RMAN. The standby is the RAC with ASM. No need down time. (from Solaris Space to Linux - this may be a problem)
3. At the cutoff time, activate the standby DB from the RAC ASM.
If feasible, do we have some detail guild line for each step?

Using ZFS for Oracle RAC 11gR2 binaries

Hi,
We have following scenario,
Two Node Cluster: Oracle RAC 11Gr2 with Clusterware on Solaris 10
We want to keep Oracle & Clusterware binaries on ZFS mirror file system on each node locally and for Data files, FRA, Voting disks & OCR on shared SAN using ASM.
My question, is the above scenario certified by Oracle or can we keep Oracle binaries on ZFS...?
Will appreciate your input.
Thanks

Well my confusion started after reading this doc on oracle support:
Certification of Zeta File System (Zfs) On Solaris 10 for Oracle RDBMS [ID 403202.1]
"Oracle database 10gR2 (10.2.0.3 and higher patches), 11gR1 (11.1.0.6 and higher patches) and 11gR2 (11.2.0.1 and higher patches) are certified with Solaris 10 ZFS on Sparc 64-bit and Solaris x84-64. See Solaris ZFS_Best_Practices_Guide. This is for single instance ONLY. ZFS is currently not applicable to RAC and not Certified to use it as a shared filesystem."

Oracle rac 11gr2 + sga

Hi all,
I have a 2 nodes rac 11GR2 on linux redhat with 12Go RAM each one.
Since 15 days, a dba add more memory on each node (+ 24Go RAM) and modify SGA like :
On each node :
create a pfile from spfile, modify memory_max_target on pfile (from 7Go to 8Go), and restart each instance from this pfile.
Now, the problem are :
Each node consume 36Go of 36Go RAM,
The parameter spfile is empty (show parameter spfile).
Do you an idea why all RAM is consumed on each node ?
Thanks.

Problem 1: Why is that a problem? How did you establish 36 Gb is used. The Unix tools are notoriously for providing incorrect information as the SGA is accounted for in every process.
Problem 2: Evidently the "DBA' used an incorrect procedure to change these parameters, and didn't convert the pfile to spfile again, and started using the 'startup pfile' command.
The action plan for this twofold
- educate the "DBA' or don't hire him anymore
- use the create spfile from pfile command, and restart the database.

RAC 11GR2 + VIP

Hi all,
I have a cluster RAC 11GR2 with 2 nodes on a site A (datacenter).
I have used 1 IP SCAN et 2 VIP.
The scan IP is 10.XXX.X.181
The rac1-vip is 10.XXX.X.165
The rac2-vip is 10.XXX.X.166
I used /etc/hosts file and not the dns for the moment.
These IP are used on a LAN.
Now, i need to attack this RAC 11GR2 via a WAN (on a site B) and so via other IP adress.
How can i do to make this? Do you have an idea ?
Thanks.

can you be more specific ? You want to setup new environment similar to you have in datacenter you mentioned?
