To view sample configuration files for SF Oracle RAC

1. Change directories to the find the sample main.cfs:

   # cd /etc/VRTSvcs/conf/sample_rac

2. Enter:

   # ls *sfrac*
   sfrac07_main.cf sfrac08_main.cf

   The following files include CVM/VVR configuration examples:

   • For the primary: sfrac_07_main.cf

   • For the secondary: sfrac_08_main.cf

   See Sample Storage Foundation for Oracle RAC configuration files.

To view sample configuration files for SF Sybase CE

1. Change directories to the find the sample main.cfs:

   # cd /etc/VRTSagents/ha/conf/Sybase/

2. Enter:

   # ls cvmvvr*

   The following sample main.cf files illustrate the VCS configuration changes after setting up an existing database for replication:

   See About sample main.cf files for Storage Foundation (SF) for Sybase ASE CE.

To modify VCS on the primary site

1. Log into one of the nodes on the primary cluster.
2. Use the following command to save the existing configuration to disk, and make the configuration read-only while you make changes:

     # haconf -dump -makero

3. Use the following command to make a backup copy of the main.cf file:

   # cd /etc/VRTSvcs/conf/config
   # cp main.cf main.orig

4. Use vi or another text editor to edit the main.cf file. Review the sample configuration file after your product installation.

   Add a failover service group using the appropriate values for your cluster and nodes. Include the following resources:

   • In a shared disk group environment, currently only the cvm master node should be assigned the logowner role.

   • IP resource

   • NIC resources

   The following are examples of RVGLogowner service group for the different platforms.

   Example for Oracle RAC:

   Please see the section "CVM master node needs to assume the logowner role for VCS managed VVR resources" in the Cluster Server Bundled Agents Reference Guide for more info.

   group rlogowner ( 
       SystemList = { sys1 = 0, sys2 = 1 } 
       AutoStartList = { sys1, sys2 } 
       ) 
   
       IP logowner_ip (
           Device = eth0
           Address = "10.10.9.101"  
           NetMask = "255.255.255.0"  
           )
       NIC nic (
           Device = eth0
           NetworkType = ether
           NetworkHosts = "10.10.8.1"  
           ) 
   RVGLogowner logowner (  
        RVG = dbdata_rvg  
        DiskGroup = dbdatadg  
        )
   requires group RVGgroup online local firm
   logowner requires logowner_ip
   logowner_ip requires nic

5. Add the RVG service group using the appropriate values for your cluster and nodes.

   Example RVGgroup service group:

   group RVGgroup ( 
        SystemList = { sys1 = 0, sys2 = 1 } 
        Parallel = 1 
        AutoStartList = { sys1, sys2 } 
        )
   RVGShared dbdata_rvg ( 
        RVG = dbdata_rvg 
        DiskGroup = dbdatadg 
        ) 
        CVMVolDg dbdata_voldg (  
            CVMDiskGroup = dbdatadg  
            CVMActivation = sw
            CVMVolume = { dbvol, dbdata_srl }  
            )
   requires group cvm online local firm
   dbdata_rvg requires dbdata_voldg

6. Modify the database service group using the appropriate values for your cluster and nodes:

   • Define the database service group as a global group by specifying the clusters on the primary and secondary sites as values for the ClusterList group attribute. See the bolded attribute in the example that follows.

   • Add the ClusterFailOverPolicy cluster attribute. Veritas recommends using the Manual value. See the bolded attribute in the example.

   • Add the RVGSharedPri resource to the group configuration.

   • Remove the CVMVolDg resource, if it has been configured in your previous configuration. This resource is now part of the RVG service group.

   • Specify the service group (online, local, firm) to depend on the RVG service group.

   • Remove the existing dependency of the Database service group on the CVM service group. Remove the line:

     requires group CVM online local firm

   • Remove the existing dependency between the CFSMount for the database and the CVMVoldg for the database. Remove the line:

     dbdata_mnt requires dbdata_voldg

   See configuration examples below.
7. Save and close the main.cf file.
8. It is advisible to modify "OnlineRetryLimit" & "OfflineWaitLimit" attribute of IP resource type to 1 on both the clusters:

   # hatype -modify IP  OnlineRetryLimit  1

   # hatype -modify IP  OfflineWaitLimit  1

9. Use the following command to verify the syntax of the /etc/VRTSvcs/conf/config/main.cf file:

   # hacf -verify /etc/VRTSvcs/conf/config

10. Stop and restart VCS.

    # hastop -all -force

    Wait for port h to stop on all nodes, and then restart VCS with the new configuration on all primary nodes:

    # hastart
