Perform the following verification tests to ensure that you have correctly installed and configured Sun Cluster HA for Sybase ASE.
These sanity checks ensure that all of the nodes that run Sun Cluster HA for Sybase ASE can start the Sybase ASE data server. These checks also ensure that other nodes in the configuration can access the Sybase ASE data server. Perform these sanity checks to isolate any problems with starting the Sybase ASE software from Sun Cluster HA for Sybase ASE.
Log in to the node that masters the Sybase ASE resource group.
Set the Sybase ASE environment variables.
The environment variables are the variables that you specify with the Environment_file extension property. See Table 1–2 for information on setting these environment variables.
Verify that the Sun Cluster HA for Sybase ASE resource is online.
# scstat -g
Inspect the Sybase ASE logs to determine the cause of any errors that have occurred.
Confirm that you can connect to the data server and execute the following test command.
# isql -S adaptive-server -U sa -P password isql> sp_help isql> go isql> quit
Kill the process for the Sybase ASE data server.
The Sun Cluster software restarts the process.
Switch the resource group that contains the Sybase ASE resource to another cluster member.
# scswitch -z -g resource-group -h node
Log in to the node that now contains the resource group.
Sybase ASE client connections cannot survive a Sun Cluster HA for Sybase ASE switchover. If a switchover occurs, the existing client connections to Sybase ASE terminate, and clients must reestablish their connections. After a switchover, the time that is required to replay the Sybase ASE transaction log determines Sun Cluster HA for Sybase ASE recovery time.
Each instance of the Sun Cluster HA for Sybase ASE data service maintains log files in the /opt/SUNWscsyb/log directory.
These files contain information about actions that the Sun Cluster HA for Sybase ASE data service performs. Refer to these files to obtain diagnostic information for troubleshooting your configuration or to monitor the behavior of the Sun Cluster HA for Sybase ASE data service.
