Usage

Download (see below) your licensed IBM MQ 8.0.0.2 software and copy it to the files/archives directory of MQ charm.

For e.g:

• Go to the files/archives directory.

• Copy the WS_MQ_8.0.0.2_FOR_LIN_ON_LE_POWER.tar.gz file to this directory for POWER LE base machines. For x86_64, use WS_MQ_V8.0.0.2_LINUX_ON_X86_64_I.tar.gz.

• The file name you have could be different from the example above (but with the .gz extension). Ensure a backup copy of the file.

To install the downloaded binaries you must agree to the IBM license. The license file(s) can be found under the files/archives/licenses directory on extraction of IBM MQ software using the following command:

tar xvfz *.gz  --strip-components=1

The license can also be viewed by running the following command after extracting IBM MQ to the files/archives directory:

./mqlicense.sh -text_only

Run the following to deploy this charm:

juju deploy ibm-mq

At this point the charm will wait until the user accepts the license. If you agree to the license, run the following command:

juju set ibm-mq accept-ibm-mq-license=True

In order to create MQ objects like queue, it is required that some of the system configurations be updated. Details provided at IBM Knowledge Center.

The Charm updates the following system configuration:

• In /etc/sysctl.conf:

  fs.file-max = 524288
  kernel.shmmax = 268435456
  

• In /etc/security/limits.conf:

  mqm              hard    nofile          10240
  mqm              soft    nofile          10240
  

• Adds user ubuntu to group mqm.

Verify these changes have been made successfully if MQ throws up any errors.
