command-level API. Application support is available for both single-byte and double-byte

character-set based applications.

Basic Mapping Support (BMS) maps are source-compatible, provided they use only CICS

family base level BMS when ported to CICS Transaction Server for iSeries. The CICS

macro-level API is not supported by CICS for iSeries. CICS for iSeries offers server support

for direct communication with workstation-based CICS clients over SNA APPC links, without

the need for an intermediate CICS OS/2 server.

Improved data integrity is ensured with CICS for iSeries exploiting the OS/400 two-phase

commit capability. When a CICS for iSeries application updates multiple systems, it ensures

successful updates of all files and backs out partial updates if the full transaction is not

completed. CICS for iSeries two-phase commit support provides a backward recovery facility.

The Inter-Systems Communications (ISC) facilities of CICS for iSeries allows connectivity to

other CICS platforms, giving access to both applications and data on those systems. CICS for

iSeries supports ISC functions on the following products:

• CICS for iSeries (other iSeries servers running CICS for iSeries)

• CICS/ESA V3R2 and V3R3

• CICS/MVS V2R1

• CICS/VSE V2R1

• CICS OS/2 V1R2 and V2R0

• CICS/6000 V1R1

CICS for iSeries InterSystem Communications (ISC) capabilities allow OS/400 users to share

data and applications with other CICS systems. Enhancements include a binary call interface

from other languages and more simplified OS/400-based administration.
