When you start Sybase Central, the main window opens, displaying the ASE plug-in, with the list of icons of the clusters and instances to which you have previously connected. If the cluster is running, a green triangle appears inside the icon next to the cluster name.
If you have difficulty connecting to a server or viewing
it in the tree view in the left pane, check to make sure the Connection
profile found in the toolbar under Tools | Connect contains
the port number associated with the server in the interfaces file.
If you are using PC-Client on Windows check the port number
associated with the server in the %SYBASE%\ini\sql.ini file.
The fastest way to connect to a running cluster in the list is to right-click the cluster name and select Connect. The ASE plug-in uses the previous connection data to make the connection. If a cluster does not appear in the tree view, you can find it with Server Discovery or provide the cluster’s host and port, login name, and password information. Either method starts by clicking the Connect icon in the toolbar near the top of the Sybase Central window.
If you know the required connection information, enter this into the appropriate fields in the Connect window. If you do not have the host and port number for the cluster or a cluster node, enter the login name and password and click Find. The Unified Agent searches for clusters and provide a list of those available. If the list does not include the cluster you are searching for, see “Changing server discovery settings” for more information.
Select Tools | Connect.
If you are running multiple registered Sybase Central plug-ins, select the ASE plug-in.
Enter the login name you want to use to connect to the instance.
Enter the password for the login.
Select the cluster name from the Server Name list, which is populated with entries from the interfaces file, or type in the host and port of a cluster node. In Windows, with PC Client, it is populated from sql.ini file.
(Optional) Specify the host and port of an instance within the cluster.
Click OK.
Right-click the cluster icon and select Connect. The cluster icon’s color changes from gray to blue when it connects.
Changing server discovery
settings
Navigate to Tools | Adaptive Server Enterprise | Preferences then select the Server Discovery tab.
Check Enable Server Discovery
Select Add.
Select the discovery method from the scroll menu.
JINI – an open architecture that enables developers to create network-centric services that are highly adaptive to change. JINI offers a standard lookup service for discovery.
User Datagram Protocol (UDP) – a network protocol that provides a procedure for application programs to send messages to other programs with a minimal protocol mechanism.
If UDP is used, only servers on the same subnet as the
one on which Sybase Central is running are discovered.
If you selected JINI in the previous step:
Select the host of the JINI server
Select either the default host and port or enter new ones
Click OK.
To add or edit a discovery filter, click Filters. Server Discovery uses only the selected filters for its search. To specify a filter:
Click Add.
Select Enable this Filter.
Select the target you want filtered, Host, Name, OS, Platform, Port, Release type, Status, Version.
Select the condition: contains, does not contain, is, is not, starts with, ends with.
Enter the condition string you want Server Discovery to filter on.
Click OK.
Configure the ASE plug-in to discover clusters currently running on the system. Use
Remove – to remove a discovery service from the list.
Edit – to edit the settings for a current discovery service.
Up – to move the selected discovery service up the list.
Down – to move the selected discovery service down the list.
