imqkeytool
imqkeytool(1M) System Administration Commands imqkeytool(1M)
NAME
imqkeytool - generate a self-signed certificate for secure communication
SYNOPSIS
/usr/bin/imqkeytool [-broker] [-servlet keystore_location]
/usr/bin/imqkeytool -h
DESCRIPTION
The imqkeytool utility generates a self-signed certificate for secure communication. The certificate can be used by a broker instance to
establish a secure connection with a client, or by a Message Queue-supplied HTTPS servlet to establish a secure connection with a broker
instance. An HTTPS servlet is an SSL-enabled varient of the HyperText Transfer Protocol that establishes a secure connection with a broker
instance.
Without an option, imqkeytool generates a self-signed certificate for a broker instance.
imqkeytool uses command line options to specify whether the certificate is used by a broker instance or by a servlet.
OPTIONS
The following options are supported:
-broker
Generate a self-signed certificate for the broker and places it in the Message Queue keystore. All broker instances running on a system
must use the same certificate.
-h
Display usage help. Do not execute anything else on the command line.
-servlet keystore_location
Generate a self-signed certificate for an HTTPS servlet and places it in keystore_location.
keystore_location refers to the location of the keystore. You should move this keystore to a location where it is accessible and read-
able by the Message Queue HTTPS servlet to establish a secure connection with a broker.
ENVIRONMENT VARIABLES
The following environment variables affect the execution of this command:
IMQ_JAVAHOME Specify the Java 2 compatible runtime. When this environment variable is not set it defaults to /usr/j2se.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
FILES
/etc/imq/keystore Contains Message Queue keystore in which imqkeytool stores a self-signed certificate for brokers.
