Before you install CICS® Universal Client,
perform the following steps as appropriate:
- Check that your operating system is supported; see Supported software for
supported operating systems.
- Log on as root.
Check the root user's umask to ensure that files created during
the installation are readable by the user IDs that will run the CICS Transaction Gateway.
A umask of 077 restricts access to the root user that installed the CICS Transaction Gateway; a umask of
022 allows all users to run the CICS Transaction Gateway
.
- Linux® operating
systems: Issue the following command from the command line:
umask 0022
- Close down any programs that are running, including the following:
- Client daemon (issue
the cicscli -x command)
- Configuration Tool
- The
installation process can upgrade from the CICS Universal Client Version
5.1 or later. Remove any other versions of the CICS Universal Client or CICS Transaction Gateway before installing
this product. Remove any beta versions of the product.
