On Solaris, you can uninstall the IBM® MQ server or client using the pkgrm command.
Before you begin
If any updates have been applied, remove them before starting
this uninstallation procedure. For more information, see Solaris: Restoring
the previous maintenance level on IBM MQ .
Restriction: On
Solaris, you cannot remove components from an install. There is no
supported method of doing this.
Procedure
-
Stop all IBM MQ applications associated with the installation you are uninstalling.
-
For a server installation, end any IBM MQ activity associated with the installation you are uninstalling:
-
Log in as a user in the group
mqm
.
-
Set up your environment to work with the installation you want to uninstall. Enter the following command:
. MQ_INSTALLATION_PATH
/bin/setmqenv
where
MQ_INSTALLATION_PATH
refers to the location where
IBM MQ is installed.
-
Display the state of all queue managers on the system. Enter the following command:
-
Stop all running queue managers associated with the installation you want to uninstall. Enter the following command for each queue manager:
-
Stop any listeners associated with the queue managers. Enter the following command for each queue manager:
-
Log in as root.
-
Uninstall IBM MQ using pkgrm:
-
On a system with a single installation, enter the following command:
-
On a system with multiple installations:
pkgrm mqm-suffix
where
suffix is the
unique name given to the packages when
crtmqpkg was run at installation time.
suffix is included in each of the package names that belong to a particular
installation. The first installation on the system does not have a
suffix, and is
uninstalled using the same method as for a single installation.
If a package has a dependency on mqm
, pkgrm returns the name of the package. Uninstall the dependent packages first.
Results
After uninstallation, certain files under the directory trees /var/mqm and /etc/opt/mqm are not removed. These files contain user data and remain so subsequent installations can reuse the data. Most of the remaining files contain text, such as INI files, error logs, and FDC files. The directory tree /var/mqm/shared contains files that are shared across installations, including the executable shared library libmqzsd.so.
What to do next
- If the product successfully uninstalled, you can delete any files and directories contained in the installation directory.
- If there are no other IBM MQ installations on the system, and you are not planning to reinstall or migrate, you can delete the /var/mqm and /etc/opt/mqm directory trees, including the file libmqzsd.so. Deleting these directories destroys all queue managers and their associated data.
