Syntax

corevector  [-l] [-s [-f]] [-c arg] [-?]  

-l

List the current settings.

-s [-f]

Set [f = force] the core dump vector using the arguments noted for the -c option.

-c

Clear the core dump vector using the following options:

• all - coredump files on all Communication Manager restarts.

• warm - coredump on warm restart request.

• cold2 - coredump on cold2 restart request.

• reload - coredump on reload (reboot) restart request.

• insane - coredump on system insane condition.

• single - coredump on single process restart and killing of TERMINAL processes.

Description

corevector is used to request or clear coredump requests. The core dump files are generated prior to the execution of the restart requested. After the core files are taken, a reload of Communication Manager processes is executed. Specifying a single process restart will also create a core file for terminal processes, e.g., map.

When the core files are to be taken, the state of health is lowered to force a server interchange. The system then waits to allow the interchange to occur (all processes are stopped), checks to ensure the standby server is now active, and generates the core files. The core files are only taken on the ACTIVE server unless the -f (force) option is specified.

In a simplex server configuration, the -f option is necessary.

corevector accepts multiple arguments, for example, corevector-s warm cold2
