I am having 2 data centers within 1/2 km distance. And we kept each vote disk in once site. In case of site failure, the cluster needs a 3rd set. We don't have 3rd site.
Last open world, Oracle announced that oracle storage on cloud as announced. If I get the small space on the cloud, can i put my 3rd vote disk on the cloud?
We use extended RAC 11gR2 on two servers in two different server rooms.Data are stored on ISCSI devices, mounted from "storage" linux hosts on a network called "SAN".Third voting disk is also stored on a ISCSI device mounted from a "quorum" linux host on our "PUBLIC" network.The RAC interconnect link is on a separate "PRIVATE" network.
During tests, when we totally disconnect the "SAN" link between the two servers, clusterware has an undefined behaviour.Sometimes (more often) it crashes, sometimes one node stays alive.At this moment, each RAC server is able to access only the ISCSI storage in its own server room, and the two servers are able to access the third voting disk (because it is on a separate network).
I am installing RAC 11GR2 in VMWARE on OEL 6.3. Everything went smooth but when i tried to configure ASM , I get below messages.
[oracle@RAC1 ~]$ /etc/init.d/oracleasm configure-bash: /etc/init.d/oracleasm: No such file or directory.
We have 2 servers running Oracle 11gR2 Window server 2008 64 bit RAC. Today I add new shared disk visible from both servers. All our data placed on ASM partitions, but we need Windows volume for exchanging some data between servers & users;Actions:then i have prepare disk on shared storage from 1st node, run diskmfmt.msc & rescan disks when windows recognizes new hdd, initialize it.create an Extended partition & Logical drive & Assign drive letter. from another nodes, make sure no drive letter is assigned.
Sometimes Windows automatically assign drive letter. If drive letter is assigned, right click & Change drive letter & Remove. from 1st node, format this logical drive using ocfsFormat.exe after execute below scripts i have face some issues
E:app11.2.0gridcfs>ocfsformat /m P: /c 1024 /v DATA /f /d /aReg Get Cluster Name(): Reg Query ValueEx for CFS_CLUSTER_NAME failed with error 203
This indicates that the Cluster Name has not been configured on this node for OCFSThe volume formatted in this condition will be seen by all nodes running OCFS.

I want to install an active / passive Oracle Configuration for our new 11gR2 system. We do not want to go full blown RAC as yet. We already have an 11gR2 instance that I plan to CLONE to the production server(s).
So. detail the steps that I need to follow .
i.e.
configure the 2 servers (VIFs/Interconnects)
Install GRID/CRS
Clone over the database (do I do this as a SINGLE NODE RAC?)
I have a small problem resizing an ASM disk group . I've had a lun with size 50G and added on it an asm disk called LUN1D1. Then I have created a DISK GROUP called data1 (external) witch contain LUN1D1. DATA1 was then made asm volume. So I have an asm volume with size 50G and I need it to be 100G.
Now I have increased the size of the lun with 50G (100G in total). I have rescanned the LUN and os see the new size. The problem is I can not re size DISK GROUP data1 or disk LUN1D1.

I've installed GI 11.2.0.3 on AIX 7.1.And today I noticed strange ASM's behavior:
-bash-3.2$ getconf DISK_SIZE /dev/rhdisk2

I guessed that was because of LUN size (it was exceed 2 TB)After that I dinamically shrinked LUN size on our external storage, rebooted and perfomed cfgmgr command on both nodes. But I still have no enough free space.
-bash-3.2$ getconf DISK_SIZE /dev/rhdisk2

I am trying to install Oracle RAC 11g on Oracle Linux via Virtual Box. My host server is windows. How to create shared storage on windows?
View 5 Replies View RelatedWe have two database servers(10g with OEL 5) to be clustered and two visible disk groups to each of those nodes. So question is can we choose only one disk group as a shared storage leaving the rest one as the redundant copy during database a creation window while installing the database. Because some of us argue that oracle database has a built-in capability to decide on what level of RAID we store our data.

Am planning to install oracle RAC 11g on linux server. Have doubt on installation of clusterware or grid infrastructure first .?I think grid infrastructure covers clusterware and ASM both and then oracle 11g software to be installed. But how to download grid insfrastructure software. Will it come with oracle 11g software..? or need to download it seperately.? Because when i try to download oracle RAC 11g which gives link to download the 11g software not grid.

I have been reading a lot of documentation regarding oracle services and I have an ok understanding of how they work. However, I have a general question regarding configuring services using Oracle RAC. For instance, if I have a 2 node oracle 11GR2 RAC on a Linux Redhat server. I have an application that connects to a service I have created. I create the service as follows.
srvctl add service -d ORCL_RAC -s APP_SERVICE -r ORCL_RAC1,ORCL_RAC2
The tnsnames contains:
APP_OLTP =
(DESCRIPTION =
(LOAD_BALANCE = ON)
(FAILOVER = ON)
[code]...
My questions are as follows:
1) When I do a 'srvctl status service -d ORCL_RAC', should I see the service running on both nodes of the RAC? Or does it run only one node, then it will fail over to the other when needed?
2) If I have a RAC environment where I see two services created (RAC_SRV1 and RAC_SRV2). I see that RAC_SRV1 is only running on node1 and RAC_SRV2 is only running on node2. There are two applications sharing the same database, one application is using RAC_SRV1 and the other application is using RAC_SRV2. Am I correct in thinking that there is no failover available here? If node1 goes down, the application connecting to RAC_SRV1 will not be able to connect to node2 right?
3) In the case of the scenario in question 2 above, would it be best practise to simply create one service and have both applications connecting to the one service? Could I configure the one service to point connections from one application to node1 and connections from the other application to node2?
We are in process of upgrading 10g (RAC) database to 11g(RAC), does the oracle client software must also be upgraded to 11g or the 10g client can be used for 11g database connectivity, since there are thousands of end users it is very difficult to upgrade all the clients.What is the best approach for client software?
