Problems installing the product

This information describes problems that you might meet when installing or uninstalling the CICS® Universal Client.

A message indicates that the CICS Universal Client is running

You might see this message when migrating from an earlier version, or when installing the product. Check the following components, and stop them as necessary:
Client daemon
This can be seen in the process list as cclclnt. See The cicscli command for information on stopping the Client daemon.
Configuration Tool
Close the Configuration Tool.

Installation fails with a ServiceException message

Symptoms
The following message is seen during installation:
>WARNING: could not write using log service: ServiceException:
(error code = 200; message = "/tmp/cicstgInstall.log 
(Permission denied)";
severity = 0; exception = >[java.io.FileNotFoundException: 
/tmp/cicstgInstall.log (Permission denied)])
Cause
A log file from a previous installation of the CICS Universal Client was created by the root user ID. The current installation is being attempted by a non-root user ID that cannot update the log file; this causes the installation to fail.
Solution
Only root can install the CICS Universal Client. Change to the root user ID and rerun the installation.

Silent installation fails

If a silent installation does not work correctly, it might not send an error to the console that produced the problem. Appending -is:log <file_name> to the installer command causes details of any errors to be output to a file. For example, to install silently using response file responseFile, and log errors to logFile, enter the following command:
installer -options "responseFile" -silent -is:log logFile.txt
