Oracle Names Control Utility

The Names control utility (namesctl) is a basic utility for controlling Oracle Names servers. This utility does not work on Net8 clients; it is only used on the Oracle database server that contains the Names database. There are several common namesctl commands, including:

  1. NAMESCTL RESTART: Restarts the Names server.
  2. NAMESCTL SET PASSWORD: Registers passwords for privileged Names server operations such as RELOAD and STOP.
  3. NAMESCTL SET SERVER: Changes the current Names server.
  4. NAMESCTL SHOW SERVER: Displays name and version of current Names server.
  5. NAMESCTL SHOW STATUS: Displays general status information about the Names server.
  6. NAMESCTL SHOW TRACE_FILE_ NAME: Shows the name of the file to which the Names server writes the trace information.
  7. NAMESCTL SHUTDOWN or STOP: Stops the Names server.
  8. NAMESCTL START or STARTUP: Starts the Names server.
  9. NAMESCTL STATUS: Displays the status of the current Names server.
  10. NAMESCTL STOP: Stops one or more Names servers.
The namesctl utility is very similar to the lsnrctl utility in syntax.
