RAC & Failsafe :: CRS Is Not Starting?
Oct 13, 2011I am getting problem while starting the CRS. Below is the necessary details:
1) I am using oracle 11g R2 RAC, with 2 node named RAC1 and RAC2
2) I have 3 diskgroup named DATA, DATA1, DATA2
3) OCR and voting disks are stored on ASM diskgroup
On node RAC1, CRS is started and /etc/oracle/ocr.loc is having the below entry:
ocrconfig_loc=+DATA
ocrmirrorconfig_loc=+DATA1
On node RAC2, CRS is stopped and /etc/oracle/ocr.loc is having the below entry:
ocrconfig_loc=+DATA
ocrmirrorconfig_loc=+DATA2
note the difference in "ocrmirrorconfig_loc". The difference was occured because I updated the OCR location on RAC1 when RAC2 was down.
Now I am trying to repair the RAC2 using below command. This command must be run as root user when HA service is started but CRS must be stopped.
ocrconfig -repair -replace +DAT2 -replacement +DATA1
but this showing error "PROT-21: Invalid parameter", because to run this command diskgroup must be mounted. But diskgroup cannot be mounted until the CRS start. SO this is a conflicting situation.
RAC & Failsafe :: DB Migration To New SAN?
Apr 30, 2012We have to perform migration for our RAC database to new SAN that is at new data centre. Since OS is IBM AIX, we can take backup from mksysb for VG and and storage will migrate data from OLD SAN to NEW SAN.
But even we restore VG and SAN data but since our old SAN is emc and new SAN is hitachi, so disk path for all the asm disk group will be changed.
So is there will be any way to rename this disk path for disk group..
RAC & Failsafe :: How To Implement Non-RAC
Jan 12, 2013We have an Implementation of Non-RAC (Single Instance with Existing ASM-RAC as storage) and below is the Details,
The client have a Real Application Cluster configuration on their AIX Server from there Data Center and they want to implement a Single instance Database that will used ASM as Storage and the storage or Disk that they want to use is the same Disk or Mirror copy of the Disk from their RAC Database.
Scenario:
-The AIX Server that they have is a one-way Hardware Mirroring (PPRC) only and it is not designed to run a 24/7 activity.
-DATAGUARD is not an option.

RAC & Failsafe :: RMAN Duplicate DB For RAC
Jan 26, 2004We have a script which uses the duplicate functionality of RMAN. It was designed for a standalone database. Now I need to make it work for a cluster DB (RAC installation).
1. Does RMAN support this?
2. Do I need to make separate executions for both the nodes of the cluster?
We are currently blocked because we have no way of getting our system running without this!
******************************8
First attempt:
oracle@sf23> ./nsr_adv_duplicate_db.sh -d ADVFRW_sf25 -t ADVFRW1 -r RCAT -n sys -p sys ->
3808 11:52:49 ----- Starting Cloning Procedure -----

...

5548 12:27:07 Original DB is 'ADVFRW'

[code].......
Now we have contrary error messages. Target DB name ADVFRW does not work, because on the target nodes there are configuration files for the node specific DB names (ADVFRW1.ora on first node resp. ADVFRW2.ora on second node). But with the node specific DB name the script fails, because it does not match with the DB name of the source system.

I read at various places but not sure of the sequence For database DB with database instance DB01 and DB02 having ASM instances ASM01 and ASM02 on node1 and node2, I understand following would be the sequence
1)
Login as root on node1
cd $CRS_HOME/bin
./crsctl start crs
2)
Login as root on node2
cd $CRS_HOME/bin
./crsctl start crs
3)
login as oracle on node1
$ORACLE_HOME/bin/srvctl start nodeapps -n node1
4)
login as oracle on node2
$ORACLE_HOME/bin/srvctl start nodeapps -n node2
5)
login as oracle on node1
start ASM instance on node1
$ORACLE_HOME/bin/srvctl start asm01 -n node1
6)
login as oracle on node2
start ASM instance on node2
$ORACLE_HOME/bin/srvctl start asm02 -n node2
7)
Start oracle database (from any node)
$ORACLE_HOME/bin/srvctl start database -d DB
A. confirm if the above sequence is correct?
B. This sequence if corrrect, is same for 10g and 11g?
C. Is shutdown sequence exact reverse of the above?

View 7 Replies View RelatedRAC & Failsafe :: Changing Disk Paths In ASM
Jul 13, 2012We are about to undertake a storage migration of our RAC environment from EMC to XIV storage.
The migration method we are using means that we will be presented with identical disks post the migration, however the UNIX paths to the disk devices will be changing. Using our migration method it is not possible to present the old and new devices at the same time.
Therefore once the migration is complete i need to update the device configuration to reflect the new paths. I believe this is done using the following techniques but I am unsure as some of the documentation is ambiguous and I have not done this before
Changing path to Voting Disks
crsctl add css votedisk <new_path_to_disk> -force
crsctl delete css votedisk <old_path_to_disk> -force
Changing path to OCR Disks
ocrconfig repair ocr <new_path_to_ocr>
ocrconfig repair ocrmirror <new_path_to_ocrmirror>
Changing paths to ASM disks
alter system set asm_diskstring='<new_device_path>' scope=both;
