Automate startup and shutdown on UNIX

You can modify startup and shutdown scripts on UNIX™ to automatically start and shut down the database server.

UNIX startup script

Modify the UNIX startup script to start the database server automatically when your computer enters multiuser mode.

  1. Add UNIX and database server utility commands to the UNIX startup script so that the script performs the following actions:
    • Sets the INFORMIXDIR environment variable to the full path name of the directory in which the database server is installed.
    • Sets the PATH environment variable to include the $INFORMIXDIR/bin directory.
    • Sets the INFORMIXSERVER environment variable so that the sysmaster database can be updated (or created, if necessary).
    • Runs the oninit command, which starts the database server and leaves it in online mode.
  2. If you plan to start multiple versions of the database server (multiple residency), you must add commands in the script to set the ONCONFIG and INFORMIXSERVER environment variables and run the oninit command for each instance of the database server.
  3. If different versions of the database server are installed in different directories, you must add commands to the script to set the INFORMIXDIR environment variable and repeat the preceding steps for each version.

UNIX shutdown script

Modify your UNIX shutdown script to shut down the database server in a controlled manner whenever UNIX shuts down. The database server shutdown commands run after all client applications complete transactions and exit.

  1. Add UNIX and database server utility commands to the UNIX shutdown script so that the script performs the following tasks:
    • Sets the INFORMIXDIR environment variable to the full path name of the directory in which the database server is installed.
    • Sets the PATH environment variable to include the $INFORMIXDIR/bin directory.
    • Sets the ONCONFIG environment variable to the appropriate configuration file.
    • Runs the onmode -ky command, which initiates an immediate shutdown and takes the database server offline.
  2. If you are running multiple versions of the database server (multiple residency), you must add commands in the script to set the ONCONFIG environment variable and run the onmode -ky command for each instance.
  3. If different versions of the database server are installed in different directories, you must add commands to the script to set the INFORMIXDIR environment variable and repeat the preceding steps for each version.
