2.5.2  Creating an instance on z/OS
In this section, we explain how to create an instance on the z/OS system. To do so, complete 
the following steps:
1. Copy the control files.
2. Verify the ARS.INI file.
3. Verify the ARS.CFG file.
4. Modify the ARS.CACHE file.
5. Verify the CLI.INI file.
6. Modify the ARSSOCKD procedure.
7. Modify the ARSLOAD procedure.
Y ou can mount the Content Manager OnDemand installation directory at any mount point 
other than /usr/lpp/ars/V9R5M0. Y ou can run at different service levels with this flexibility. For 
example, a symmetric multiprocessor (SMP) might be used to install into 
SERVICE/usr/lpp/ars/V9R5M0. SERVICE/usr/lpp/ars/V9R5M0 might be copied into 
/usr/lpp/ars/V9R5M0/maint for testing. When testing is complete,  
/usr/lpp/ars/V9R5M0/maint might be copied into /usr/lpp/ars/V9R5M0 for production.
Copying the control files
To copy the control files, complete the following steps:
1. Create a directory ( /etc/ars) for maintaining the updated configuration files.
2. Create a symbolic link from the installed directory /usr/lpp/ars/V9R5M0/config to the 
/etc/ars directory, for example, ln -s /etc/ars /usr/lpp/ars/V9R5M0/config.
3. Set the appropriate access mode of 755.
ARS.INI
The ARS.INI file contains a section for each instance; each section begins with a header. It is 
created at installation time and, by default, it is configured with information for the archive 
instance. In this scenario, ARC95037 is the header line definition.
Figure 2-7 shows the content of a sample ARS.INI file.
