RAC/ASM Clusterware Installation :: Microsoft Cluster Service And ApEX - Compatible?
Jul 25, 2012
I have been asked to look at making an existing Oracle server resilant. The technology I need to use are:
- Windows 2008 R2 Enterprise SP2
- Microsoft Cluster Services
- Oracle Enterprise 11g release 2
- Oracle Fail-Safe (latest version available)
Unfortunately ApEX 4.1 and Mod_plsql are install on the existing stand-alone server. I'm afraid i know very little about Oracle and ApEX but i need to make a design decision and check fiesablilty.
I believe the HTTP service and Mod_plsql can be moved to a independant server which should work but ApEX itself must remian on the database server (i'm told).Will ApEX work in a MSCS setup? I can only find references to RAC support, RAC is out of scope.
I am using newstart cluster software. currently I have two blade servers in my system and I have configured cluster as well. right now I have one issue. I am using the ip address of 10.34.14.0/28 network for cluster but this can not be accessed from all network so I want to use different range of IP of 10.68.1.0/28 network in the same blade servers. Can I configure two different floating (cluster) IP? the first IP range is for signalling and second IP range 10.68.1.0/28 network is for OMM. I need to use both IP in two blade servers.
I'm a long time Oracle DBA but have only recently started with RAC and have never done any patching or upgrades in a RAC environment.
My environment consists of a 2 node RAC cluster, and 2 physical standbys at separate remote locations.
The database, GI, ASM, and clusterware are all at version 11.2.0.1.
I want to upgrade all components to the latest patchset which is 11.2.0.3. Eventually I also want to apply the latest PSU.
Can I do this without down time? It is a mission critical database where downtime could conceivably endanger lives. If it can't be done with zero downtime, then downtime must be kept to an absolute minimum (minutes, not hours).
I suspect the clusterware needs to be patched first and I do not know whether I can do it on one node at a time.
After installing a 4 node cluster 11.2.0.3 with 16 CPU's (4 on each node) on IBM 795 with aix 6.1 each server is using 0.5 CPU with no user load on the system. Running SIHA on one server typically uses 0.05 CPU with no user load on the system.
im having problems with CRS in a Rac installation. Because of this i cant start the database.I installed Oracle Rac 11.2.0.1 with ASM in a Red Hat 5.8 linux server. Everything was ok until a server reboot. I have 2 nodes, nodo1 and nodo2. Both got rebooted and after that im not able to start the cluster.
All the other resources seem to be just fine .
At nodo1: [root@nodo1 oracle]# crsctl start cluster -all CRS-2672: Attempting to start 'ora.cssdmonitor' on 'nodo1' CRS-2672: Attempting to start 'ora.cssdmonitor' on 'nodo2' CRS-2676: Start of 'ora.cssdmonitor' on 'nodo1' succeeded CRS-2672: Attempting to start 'ora.cssd' on 'nodo1' CRS-2672: Attempting to start 'ora.diskmon' on 'nodo1' CRS-2676: Start of 'ora.cssdmonitor' on 'nodo2' succeeded CRS-2672: Attempting to start 'ora.cssd' on 'nodo2'
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
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 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.
Oracle VM 2 Node RAC cluster Oracle 11G 11.2.0.3.0 Oracle 11g rel 2 GI
on current 2 node cluster we have GI and RAC db configured Nodes: vmorarac1,vmorarac2
we shutdown vmorarac1 to clone it to vmorarac5
on new node I have changed the hostname to vmorarac5 In /etc/sysconfig/network-scripts/ifcfg-eth0 change ip to new ip and same for /etc/sysconfig/network-scripts/ifcfg-eth1 152.144.199.210,152.144.199.211
mad echanges to /etc/hosts on vmorarac1/2 for 2 new IP address assigned to vmorarac5
Oracle Database 11.2.0.3.0 64bitI have followed most steps of this link and I came to a stop at the point where I use the Network Configuration Assistant.I have selected the following
1) Directory Usage Configuration> 2) Microsoft Active Directory> 3) Operation (2nd): Select the directory server you want to use, and configure the directory server for Oracle usage.> 4) Input my AD hostname> 5) Then it displays a message that "The directory contains an older version of the required Oracle Schema. Directory usage configuration cannot continue without the correct Oracle Schema. If you have authorization to create the directory schema then you can upgrade the Oracle Schema now. Would you like to upgrade the Oracle Schema? I have selected: Yes, I want to upgrade... and thereafter I get the errors:

I have a RAC working with SAN raw devices presented to ASM and working fine. My situation has changed since the installation of the RAC. Now I need a shared storage (with a filesystem) to upload some files (so DB can read these as external tables) for this I have used OCFS2.
As you can see I have Oracle RAC on raw ASM + shared storage on OCFS2 and for the time been all seems to be well and working perfectly. Can these coexist with out effecting the other?
I would like to build a 2-node cluster without RAC. I desire to operate 2 Oracle database instances for use by 2 separate applications. I plan to run Linux. I would like node1 to act as the primary server for the databases in application1 and node2 to act as the failover server for the databases in application1. Conversely, I want node2 to act as the primary server for databases in application2 and node1 to act as the failover server for databases in application2. Can Oracle SE and Oracle Clusterware be configured in this this way?
I am setting up a RAC cluster in Oracle 11.2.0.3 on two Windows 2008R2 nodes.I have completed all the pre-installation tasks would like to verify this by running:cluvfy comp sys -p database -n allusing the standalone download of cluvfy - I haven't installed any Oracle software as yet. This completes successfully on the remote node but fails on the local node (whichever one I run it from).
There is a lot of output but these seem to be the key problems: [1852@PRDAT217] [Worker 3] [ 2013-10-01 14:44:45.190 BST ] [WindowsSystem.deleteService:876] _WS_ deleteService2: node PRDAT217 Service OracleRemExecService result: 0|Access is denied.[1852@PRDAT217] [Worker 3] [ 2013-10-01 14:44:45.190 BST ] [NativeResult.<init>:91] NativeResult: The String obtained is0|Access is denied.[1852@PRDAT217] [Worker 3] [ 2013-10-01 14:44:45.190 BST ] [NativeResult.<init>:99] The status string is: 0[1852@PRDAT217] [Worker 3] [ 2013-10-01 14:44:45.190 BST ] [NativeResult.<init>:112]
I am trying to install Oracle RAC installation w/ guest OS OracleLinux6 on Virtualbox/Mac OS.But getting problem to set network & ip setting and yum is not able to reach oracle repository.
if anyone tried installing Oracle RAC installation w/ guest OS OracleLinux6 on Virtualbox on intel based Mac OS.
I have to manage an active passive cluster on SLES10 SP4. Oracle 10.2.0.4. All oracle binaries are on a DRBD Device on mountpoint /oradata. This mountpoint includes the binaries and all datafiles.
I havent installed these systems. At one stage on node died and got reinstalled by a system administrator. After a switch from the running node to the standby node, the cluster is not starting.
Jan 3 14:36:01 a logger: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.6114. Jan 3 14:36:14 a logger: Waiting for Oracle CSS service to be available before starting Jan 3 14:36:14 a logger: ASM instance +ASM. Wait 2.
After issuing $ORACLE_HOME/bin/localconfig add the cluster is starting, the asm instance is coming up, and also the database instance is starting.
Shortly after that the db instance dies. Alert log is showing something like recursive sql error. Looks like writing to the datafiles is not working. In asmcmd the diskgroups are showing DISMOUNTED (show MOUNTED before)
so what to do ? a) Why is it necessary to issue "localconfig add" to make the cluster starting ? b) What could be a reason for not being able to write to the database ? c) How to install an active/passive cluster ? c1) Install OS on both nodes c2) Install oracle binaries c2.1) on both nodes in the local files system and do the mapping to the drbd afterwards? c2.2) only on one node and just switch the mountpoint ?
We have 3 node RAC. In one of the node clusterware is down and also CSSD process is down. I got to know that we have to clear socket files in that node.what needs to be done instead ofclearing socket files.

We're trying to utilize Oracle RAC 11.2. We want to have two servers in our grid. These two server are installed on a VM using Hyper-V software.
common storage for asm is also developed on a VM using FreeNAS software.Now, when we try to install Grid Infrastructure the disk that is recognized as a extra drive in both servers are disabled and we can't select it as ASM storage. The OS we're using is Windows Server 2008 R2.I have to say the IP requirements are considered and the servers have two IPs.
I want to install Oracle Grid software 11g R2. What is the Latest Oracle Grid software 11g R2 version available?Is it 11.2.0.1 or 11.2.0.3?If it is 11.2.0.3, is it available in metalink download, because I see only 11.2.0.1 version in metalink download?
My application consists of Oracle RAC and Oracle Enterprise Manage (OEM) on same two nodes. I am exploring the idea of utilizing Oracle Clusterware (which is already installed with Oracle RAC) to support OEM in active passive mode.
Here is the scenario.
Node A running Solaris 10.9 on SPARC and Node B running Solaris 10.9 on SPARC. Node A and Node B are both Oracle RAC Nodes ( Active Active ) which use Shared Storage for Oracle using ASM.
Node A and Node B will run Oracle Enterprise Manager (OEM) Application in active passive scenario which will be using Oracle RAC for its database. So, both Oracle RAC and OEM are sharing same server A and B for its clusters.
Now, OEM application need a third party clusterware to fail it over. It needs clusterware to provide floating VIP and shared folder of the size of 20GB which will keep software libraries. If node A goes down, node B have access to same libraries and will come up as active.
Do you know if oracle clusterware which comes with Oracle RAC can support OEM for failing over i.e. it can provide floating VIP and shared file system?
I have deinstalled Oracle database, ASM and oracle software. I installed the oracle software, ASM and database. I have seen the error in the ASM trace called
Errors in file /opt/oracle/admin/+ASM/bdump/+asm_gmon_10518.trc:
ORA-29702: error occurred in Cluster Group Service operation ORA-29702: error occurred in Cluster Group Service operation
We had installed in node 1 & now the partition is shifted to node2 ,But installation on OID infrasturcture, when we aretrying to connect repository database, it says, hostname:<PORT> service may not be avaialble, listener may not be up.unable to connect orcl.test.com
whereas the service is running & listener is up. We copied inventory location and oraInst.loc and oratab file from node1 to node2, But still unable to connect metadata repository from infrastructure node.What are we missing here..
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 am getting "ORA-03114: not connected to ORACLE" while installing "Oracle Database 11GR2" on "Oracle RAC 11R2" cluster setup. I am getting this error at the time of "Oracle Database Configuration Assistant" configuration reaches till 39% on HP-UX 11.31 IA64 platform.
I am installaing oracle RAC 11.2.0.1. After I installed the grid infrastructure, when I ran root.sh, I got below errors;
