Location of shared configuration files
A shared configuration file must be stored in a location that can be read by all servers.
Started task Applies to z/OS® Connect Servers run by using a z/OS started task procedure.
It is good practice to use the Liberty profile's shared directory structure. The
shared.config.dir property specifies the location
<WLP_USER_DIR>/shared/config. You can use this property
name within your server configuration file. By default the value of WLP_USER_DIR
is /var/zosconnect.
Shared configuration files on z/OS
The default value of WLP_USER_DIR is /var/zosconnect. This might not be suitable if you want to use shared zFS in a Parallel Sysplex® because the /var mount point cannot be shared. However, you can customize the value of the WLP_USER_DIR environment variable before you install z/OS Connect. For more information, see Installing IBM z/OS Connect with SMP/E.
In a single LPAR, a UNIX System Services directory that is not in the ${server.config.dir} directory structure can be used so that it is not nested in the directory structure of a single server.
In a Parallel Sysplex, you can mount a shared
zFS to share a single configuration file between multiple servers. For more information about using
shared zFS in a Parallel Sysplex, see 
z/OS File System
overview. You can further improve the resilience of these file systems by using RAID arrays
and DASD mirroring technologies. Alternatively, you can share configuration files only among the
servers in each LPAR and maintain separate physical copies of the file on each LPAR. These files
must be kept in sync manually.
