Example definitions for an MSC TCP/IP link

The following series of examples show the definitions required for an MSC TCP/IP link between two IMS systems.

Local MSC link definitions

The following MSC link definitions are coded in the local IMS system.

PLNK12TA MSPLINK TYPE=TCPIP,NAME=IMS2,LCLICON=HWS1,LCLPLKID=MSC12,BUFSIZE=8192,SESSION=2
 MSLINK PARTNER=AB
  MSNAME SYSID=(2,1)

Local IMS Connect configuration member

The following MSC and RMTIMSCON configuration statements are coded in the local IMS Connect configuration member.

HWS=(ID=HWS1,XIBAREA=20,RACF=Y)
TCPIP=(HOSTNAME=TCPIP,PORTID=(9999),
 MAXSOC=50,RACFID=RACFID,TIMEOUT=5000)
MSC=(LCLPLKID=MSC12,RMTPLKID=MSC21,LCLIMS=(IMS1),RMTIMS=IMS2,
 IMSPLEX=(MEMBER=HWS1,TMEMBER=PLEX1),RMTIMSCON=HWS2)
RMTIMSCON=(ID=HWS2, HOSTNAME=HWS2.IBM.COM,PORT=8888,RESVSOC=2)

Remote IMS Connect configuration member

The following MSC and RMTIMSCON configuration statements are coded in the remote IMS Connect configuration member.

HWS=(ID=HWS2,XIBAREA=20,RACF=Y)
TCPIP=(HOSTNAME=TCPIP,PORTID=(8888),
 MAXSOC=50,RACFID=RACFID,TIMEOUT=5000)  
MSC=(LCLPLKID=MSC21,RMTPLKID=MSC12,LCLIMS=(IMS2),RMTIMS=IMS1,
 IMSPLEX=(MEMBER=HWS2,TMEMBER=PLEX2),RMTIMSCON=HWS1)
RMTIMSCON=(ID=HWS1,HOSTNAME=HWS1.IBM.COM,PORT=9999,RESVSOC=2)

Remote MSC link definitions

The following MSC link definitions are coded in the remote IMS system.

PLNK21TA MSPLINK Type=TCPIP,NAME=IMS1,LCLICON=HWS2,LCLPLKID=MSC21,BUSIZE=8192,SESSION=2
 MSLINK PARTNER=AB
  MSNAME SYSID=(1,2)

The following figure shows the IMS and IMS Connect systems at the local and remote installations. The definition statements required to define the MSC link path are shown in each IMS and IMS Connect system. Other required definition statements that are not directly related to the definition of the MSC path are omitted from the figure.

Figure 1. Example MSC TCP/IP link configuration
The figure diagrams the MSC TCP/IP link configuration defined by the preceding example definition statements. The link is depicted by a line from a local IMS to a local IMS Connect, both in a local IMSplex. The line continues from the local IMS Connect to a remote IMS Connect and finally from the remote IMS Connect to a remote IMS system, both in a remote IMSplex.
