LOGICALSERVER section definitions are deprecated and superseded by policy-based dynamic server selection definitions.
A LOGICALSERVER section definition in the configuration file (ctg.ini), provides a mapping of a logical CICS® server name to an actual CICS server name where work is to be sent. The logical CICS server name is an alias that can be passed to CICS Transaction Gateway on an ECI or ESI request. The function provided by LOGICALSERVER section definitions is incorporated into policy-based dynamic server selection and this new mechanism provides enhanced capability and flexibility for dynamic server selection.
Replace LOGICALSERVER section definitions with policy-based DSS definitions. For example the definitions:
SECTION LOGICALSERVER = PAYMONTH
Server = PAYROLLA
ENDSECTION
SECTION LOGICALSERVER = PAYWEEK
Server = PAYROLLB
ENDSECTION
can be replaced by the definitions:
SECTION GATEWAY
....
DSSPolicy = POLICY1
ENDSECTION
SECTION DSSPOLICY = POLICY1
SUBSECTION MAPPINGS
PAYMONTH=GROUP1
PAYWEEK=GROUP2
ENDSUBSECTION
SECTION DSSGROUP = GROUP1
Servers = PAYROLLA
Algorithm = Failover
ENDSECTION
SECTION DSSGROUP = GROUP2
Servers = PAYROLLB
Algorithm = Failover
ENDSECTION
