During startup of the Transportation Manager Request Server (TMRS) or Transportation Manager Request Handler (TMRH), the relationship between Optimizer Instances and Optimizer Instance Groups will be established. Parameter -TPINSTANCEGROUPS is used to define the Optimizer Instances in each Optimizer Instance Group. The same Optimizer Instance could belong to more than one group. Within each group, the sequence in which Optimizer Instances are defined will indicate their relative order or preference.
The format of -TPINSTANCEGROUPS parameter is:
-TPINSTANCEGROUPS[group]:[instance],[instance]...;[group]:[instance],[instance]...
For example:
-TPINSTANCEGROUPS LONG:OPT1,OPT2,OPT3;SHORT:OPT4,OPT3
In group LONG, instances supported would be OPT1, OPT2 and OPT3, in that order of preference.
In group SHORT, instances supported would be OPT4 and OPT3, in that order of preference.
