To support a switchable data group in a remote journaling environment, you need to have four journal definitions configured: two for the RJ link used for normal production-to-backup operations, and two for the RJ link used for replication in the opposite direction.

In this example, a switchable data group named PAYABLES is created between systems CHICAGO and NEWYORK. System 1 (CHICAGO) is the data source. The data group definition specifies *YES to Use remote journal link. Command defaults create the data group using a generated short data group name and using the data group name for the system 1 and system 2 journal definitions.

To create the RJ link and associated journal definitions for normal operations, option 10 (Add RJ link) on the Work with Journal Definitions display is used on an existing journal definition named PAYABLES CHICAGO (the first entry listed in Figure 11). This is the source journal definition for normal operations. The process of adding the link creates the target journal definition PAYABLES@R NEWYORK (the last entry listed in Figure 11).

To create the RJ link and associated definitions for replication in the opposite direction, a new source journal definition, PAYABLES NEWYORK, is created (the second entry listed in Figure 11). Then that definition is used to create second RJ link, which in turn generates the target journal definition PAYABLES@R CHICAGO (the third entry listed in Figure 11).

Identifying the correct journal definition on the Work with Journal Definition display can be confusing. Fortunately, the Work with RJ Links display (Figure 12) shows the association between journal definitions much more clearly.
