Note:
When multiple BBjServices or PRO/5 processes are sharing the same data files, "Exclusive File Access" must be disabled in the Enterprise Manager settings on all BBjServices installations accessing the shared files. As an alternative to shared file access, BASIS recommends using data server syntax to access shared data files through a single BBjServices. This eliminates the need for shared file access and uses a central point of contact for all access to the data file. See Getting to Know More About the BBj PRO/5 5.0 Data Server for information on using BBj and PRO/5 in a shared environment.
