Applying maintenance level client updates on Windows

We can apply maintenance level updates to IBM MQ for Windows clients either interactively or by performing a silent MSI update.

About this task

We can apply maintenance to an IBM MQ client interactively by running the setup.exe program, or we can perform a silent MSI update by running the msiexec command with file IBM MQ.msi. The setup.exe and IBM MQ.msi files are both located in the \Windows\MSI\ directory of the client installation image.

Important: The server fix pack is for updating installations installed from the server DVD or eImage only and is neither tested nor supported as an update mechanism for updating client installations from the MQC91 IBM MQ Clients SupportPac.

Procedure

Access the IBM MQ installation image.
See Where to find downloadable installation images.

Interactive client update

On the client installation image, navigate to the \Windows\MSI\ directory, then run the setup.exe program.

Silent client update

From the command line, use the command msiexec to perform a silent MSI update.
- To update a computer with only a single installation, use a command similar to the following example:
```
msiexec /i "InstallationImage\Windows\MSI\IBM MQ.msi" /l*v install_log_path
/q TRANSFORMS="1033.mst" REINSTALL=ALL REINSTALLMODE=vomus
```
- To update a single client on a multi installation computer with multiple clients, use a command similar to the following example:
```
msiexec /i "InstallationImage\Windows\MSI\IBM MQ.msi" /l*v install_log_path
/q TRANSFORMS=":InstanceId2.mst;1033.mst" REINSTALL=ALL REINSTALLMODE=vomus
```

Results

When the maintenance completes we can query the maintenance level by running the dspmqver command. For more details, see Querying the maintenance level.
