Define VCS environment variables in the file vcsenv, which is located at the path /opt/VRTSvcs/bin/. These variables are set for VCS when the hastart command is run.

To set a variable, use the syntax appropriate for the shell in which VCS starts. For example, define the variables as:

VCS_GAB_TIMEOUT = 18000;export VCS_GAB_TIMEOUT
umask = 011;export umask

By default, files generated by VCS inherit the system's umask settings. To override the system's umask settings for files generated by VCS, define a umask value in the vcesnv file.
