For Qshell and spawned path command processing

Read this information to see how Qshell and spawned path command processing works.

For Qshell or spawned path command processing, the REXEC server by default returns normal output on the first connection and error output on the second connection. (The REXEC stdin, stdout, and stderr streams are mapped to file descriptors 0, 1, and 2. The QIBM_USE_DESCRIPTOR_STDIO environment variable is set to Y.) These options allow you to redirect input and output.

Choosing the Qshell command processor sets these environment variables:

TERMINAL_TYPE=REMOTE
PATH=/usr/bin
LOGNAME= user, where user is the user profile
HOME=homedir, where homedir is the user's home directory

The child job inherits any other environment variables that the exit program sets.

Spawned child processes are batch jobs or prestart jobs. They cannot do interactive I/O. See WebSphere^® Development Studio: ILE C/C++ Programmer's Guide Link to PDF for complete details on this support.
