Accessing Multiple Systems with the Same File Name

Due to constraints of Remote Unit of Work, the S (CA 2E) Distributed I/O option only applies to the primary access path of the function. There is no CA 2E control for file I/O operations contained within embedded internal functions.

When a function uses the S (CA 2E) Distributed I/O option, initial connections to the primary view of the function will use the configuration table entries specified in the configuration table for that primary view.

Since the scope of a connect affects all files and programs in the current routing step, modifying the RDB for the main file may affect any underlying processing to other database files within the master function and to any other functions called from that master function.

All functions generated under S (CA 2E) control enable function key F22 for their device designs. The default value of this key is stored in a *Change RDB command key list, and can be modified in the model. Function key F22 calls the shipped CA 2E program Y2CRDBR (Change RDB), which appears in a window. The program displays all RDBs in the configuration table for the primary view and allows application users to switch to an RDB by merely selecting one of the entries. This program indicates to users which RDB they are currently connected to.

For example:
