This section assumes that the Microsoft Cluster Server is installed on your system. Use the following command on each node of the cluster to install the new resource type “Sybase Companion Server” and Cluster Administrator extensions:
%SYBASE%\ASE-12_5\bin\sybcpnin.exe -s
%SYBASE% is the release directory for the Adaptive Server executable.
To configure Sybase Failover on Microsoft Cluster Server:
Create a cluster group. See you Microsoft Cluster Server documentation for information, then move the dedicated shared disks for the companion you are configuring into the cluster group you created. See your Microsoft Cluster Server documentation for information.
In Select | Administrative Tools | Cluster Administrator.
In Select File | Resource | New Resource.
On the New Resource window, enter:
Name – the name of the package you are configuring.
Description – a brief description of the package. This field is optional.
Resource type – select Sybase Companion Server.
Group – the group in which you want this cluster included. This field is optional.
Click OK to create this group.
Select Change Group, then select the name of the group to move the physical disk resources (data and log devices) of the primary companion to this new group. Click OK. You see the Possible Owners window.
The Possible Owners window specifies the nodes on which this resource can be brought online. Both nodes must be listed as possible owners in the right pane of this window. If the list is not correct, use Add or Remove to correct it. Select Next.
The Dependencies window lists the services that must be brought online before starting this resource. Make sure the shared disk device is listed as a dependency. Select Next.
On the ASE Server Information window, enter:
The name of the Adaptive Server you are configuring as the primary companion.
The System Administrator login for this companion (this must be sa
The System Administrator password for this login
A password check to make sure the password you entered is correct
Select Next
In the Companion Server Information field, enter the name of the Adaptive Server that is to be the secondary companion.
To configure the companions in a symmetric setup, select Symmetric, then click Next.
On the Cluster Parameters window, select Use System Generated Cluster Login. This provides a system-generated setup login that is used when the cluster logs into the Adaptive Server. Click Next. (Alternatively, you can create the login on the primary companion, assign it both the sa_role and ha_role before you perform this step.)
(Optional) On the Setup Options window, enter the path to the error log that records the steps made during this configuration. This log may be helpful if you need to call Technical Support. Select Finish.
The next window lists the configuration that you have selected for this cluster configuration. Select Back and reenter the appropriate data to change any information. When the configuration is correct, select Next to configure this cluster resource.
You see a series of messages as the two Adaptive Servers are configured. If any error messages appear, address the issues and select Next. You do not have to start over again.
When the configuration is complete, the companions are in normal companion mode in either an asymmetric or symmetric setup, depending on what you specified in the Companion Server Information window.
