When Server Ping reports no errors, but your other applications fail to run, use this information to discover the problem.
To troubleshoot a falsely successful Server Ping:
Verify that the Net-Library driver that you want to use is listed in the libtcl.cfg file.
The utility does not look in libtcl.cfg, so Server Ping can be successful, even if the libtcl.cfg file contains incorrect information. The libtcl.cfg file is in the ini subdirectory of the Sybase installation directory.
Use isql to verify that you can access Adaptive Server locally from your computer.
Use isql to verify that the databases and tables used by your client application exist.
Verify that you have a valid user login name for Adaptive Server.
Verify that you have permissions on databases and tables that are consistent with the permissions required to run your applications.
Occasionally, a Server Ping result might indicate inaccurately a successful connection to Adaptive Server because dsedit found some other application listening at the specified Adaptive Server address. dsedit does not recognize that the non-Sybase application is not an Adaptive Server. To determine if this is the case, try to connect to the server with isql.
