Appendix E Frequently Used Command Utility Commands

This appendix lists some frequently used Message Queue Command utility ( imqcmd) commands. For a comprehensive list of command options and attributes available to you from the command line, refer to Command Utility in Command Utility

Syntax

imqcmd subcommand argument [
options]
imqcmd -h|H
imqcmd -v

-H or -h provides comprehensive help. The -v subcommand provides version information.

When you use imqcmd, the Command utility prompts you for a password. To avoid the prompt (and to increase security), you can use the -passfile pathToPassfile option to point the utility to a password file that contains the administrator user name and password.

Example: imqcmd query bkr -u adminUserName -passfile pathToPassfile -b myServer:7676
