Preinstallation considerations

For detailed instructions on the SMP/E installation of the product, see Program Directory for IBM z/OS Explorer Extensions.

The IBM® Developer for z/OS® FMIDs are shared by multiple IBM products, so it is possible you already have installed one or more of the FMIDs. In this case you can reuse the existing installation and go directly to the configuration tasks.

The Developer for z/OS servers are single-system minded, and are not SYSPLEX aware. If you are using the servers in a SYSPLEX, you must ensure that the data requested by the end users (data sets, job output, z/OS UNIX files) is available on the system Developer for z/OS is installed. See Predeployment considerations for cloning Developer for z/OS to other systems.

To run multiple instances of Developer for z/OS on a single host system, see "Running multiple instances" in the IBM Explorer for z/OS Host Configuration Reference .

The file system in which Developer for z/OS is installed must be mounted with the SETUID permission bit on (this is the system default). Mounting the file system with the NOSETUID parameter prevents Developer for z/OS from creating the user's security environment, and rejects the connection requests of the client. The same is true for the file systems hosting z/OS Explorer, Java™, and z/OS UNIX binaries.
