hsmgr must be running to use Hot Swap. When Natural Access is installed, hsmgr is installed as a service and is configured to be started manually.
To run on a remote host, the utility must be physically resident on the remote host. Use a separate third-party utility such as telnet, rsh, or rexec to invoke the utility.
When debugging Hot Swap applications, run hsmgr in console mode to see Hot Swap manager messages.
To run hsmgr in console mode:
Step |
Action |
1 |
To stop any previous instance of hsmgr: Under Windows:
The Administrative Tools window appears.
The Services window appears.
The Properties window appears.
Under UNIX: Run the Hot Swap manager with the -k option to stop any previous instance of the manager: hsmgr -k |
2 |
Start the Hot Swap manager in console mode by entering: hsmgr -c |
In Solaris, if you are running the Hot Swap manager in console mode, ensure that the Hot Swap driver (hssrv) is running, otherwise startup fails. Refer to Hot Swap driver: hssrv for more information.
In Linux, ensure that the Hot Swap kernel driver is loaded. Refer to Starting Hot Swap under Linux for more information.
If the print option is on (default), messages display as boards are inserted and extracted. Each message displays in the following format:
