May 30, 2013I have few doubts in rac environment
1.In 2 node rac while adding datafile to tablespace if you forget to mention '+'then what will happen whether it is going to be create or it throws an error if it creates where exactly located and other node users how to work on that tablespace .what all steps to perform that datafile is useful for all node users.
2. In Rac environment how to check how many sessions connected to particular node.
3)In Rac any node is evicted due to network failure then after we rebuild the network .Is there any steps to do manually to access the failure node after rebuilding the network or it will automatically available in cluster group which service is perform this activity.
4.While configuring cluster ware you choose voting disk and ocr disk location and which redundancy you will choose suppose if you go for normal redundancy how many disks you can select for each file either one or two?

Sep 13, 2012 I would like get more details about single node RAC.. What is single Node RAC?..
1). just configure only one server instead of two node... same RAC installation.. cluster installation and shared disk configuration in single server itself.. in future we can add node to this ...
2). in 11gR2 having new feature Single Node RAC.. Multiple instances running on same node and configure using Cluster...
is there any advantage using single node rac(other than online upgrade to full RAC).

We made a reboot of RAC1 node and now SCAN address works correctly from RAC1 and RAC2 (used as a client) fails systematically with SCAN address but works perfectly with direct access to the database.On both nodes, SCAN address is perfectly resolved by DNS server, cluster seems correct, listeners seems correct...We have opened an SR on Metalink 4 weeks ago but we don't progress.

View 1 Replies View RelatedRAC & Failsafe :: Listener - VIP Doesn't Migrate From One Node To Another
Apr 17, 2012I have the following problem on a 10.2.0.4 Oracle on AIX 1.6...
I have 2 RAC nodes as the node # 2 goes down, the VIP migrated correctly to the node # 1, but the listener # 1 do not see the change, and just resolve to the local ip.
The same does not apply in the reverse case, when it drops the node N 1, the listener attends to the fallen VIP node and migrated.The configuration is correct and identical in both nodes, according to the documentation, but I can not find a reasonable answer.
IP node # 1.
scm1or01 192.68.60.11
scm1or01-VIP 192.68.60.13
IP node # 2
scm1or02 192.168.60.12
scm1or01-VIP 192.168.60.14
Below I write as I detect the problem: when scm1or02 is down:

I do not understand the reason, I've rebuilt the configuration of the listener, and netmgr netca tools, but the problem persists.

View 9 Replies View RelatedRAC & Failsafe :: How To Prevent VIP Transfer Back To Its Original Node Location
Nov 11, 2012Normally if node fails, VIP & resources are transferred to another node (clients need to failover).
if node is back again CRS detect this, make it as 'family member' and try transfer VIP & resources back to this node (clients will force to failover again).
this failover (despite of failover method I use) make each uncommitted transaction to be rolled back. client need to be disconnected from the service and VIP through they are connected to this service and they need reconnect to the new node - during this stage all DMLs modifications are gone, and need to be re execute.
