When pdb_version is invoked, it returns the primary data server vendor name and version, and the JDBC driver name and version for the primary database.
The actual results returned vary depending on the type of primary data server.
If the primary database connection is down or not configured, the pdb_version command returns an error.
The pdb_version command is valid when the Sybase Replication Agent instance is in either Admin or Replicating state.
