Changing server discovery settings

You need not select a single discovery method. Server discovery searches all specified discovery methods.

1. Right-click the cluster’s name.

2. Select Connect.

3. From the Connect dialog box, select Settings.

4. Select the Server Discovery tab.

5. Select the discovery method.

   • 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.

     See Chapter 2, “Installing and Configuring Unified Agent and Agent Management Console,” in Unified Agent and Agent Management Console Version 2.0 for Windows and UNIX.

   • 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 only UDP is used, only servers on the same subnet as the one on which Sybase Central is running are discovered.

6. Click Add.

7. 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

8. Click OK.

9. To add or edit a discovery filter, click Filters. Server Discovery uses only the selected filters for its search to specify a filter:

   1. Click Add.

   2. Select Enable this Filter.

   3. Select the target you want filtered, Host, Name, OS, Platform, Port, Release type, Status, Version, Build Date.

   4. Select the condition: contains, does not contain, is, is not, starts with, ends with.

   5. Enter the condition string you want filtered.

   6. Click OK.

10. Configure the Adaptive Server 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.

11. If you are using LDAP servers, select the LDAP pane:

    1. Select the LDAP server name.

    2. Use the gauge to set the search timeout period.

    3. Enter the user name and password to log in to the nodes.

    4. Select the nodes you want to log in to in the Select Cluster Nodes box.

    5. Click OK.
