Chapter 2. Setting up a Content Manager OnDemand instance 37
Figure 2-6   Single instance overview on z/OS
2.5.1  Installation overview
The path for the Content Manager OnDemand system is /usr/lpp/ars/V9R5M0 (on z/OS) and 
/opt/IBM/ondemand/V9.5 (on UNIX). From the ars directory, several directories contain the 
Content Manager OnDemand files and executable files, such as programs and procedures. 
The directories are created during the installation when you run the ARSMKDIR REXX 
routine from the installation library, ARS.V9R5M0.SARINST. The /usr/lpp/ars/V9R5M0 directory 
contains the subdirectories that are listed in Table 2-3.
Table 2-3   Subdirectories of /usr/lpp/ars
Sometimes when you choose a directory, such as /usr/lpp/ars/V9R5M0/bin, you see a 
different path when you run pwd because a symbolic link is set. A symbolic link is a file that 
contains the path name for another file or directory. Only the original path name is the real 
name. An external link is a type of symbolic link; it links to an object outside of the 
hierarchical file system (HFS). Typically, it contains the name of an IBM MVS™ dataset.
