A link to an IMS™ system requires a definition of the connection (or system) and a separate definition of each of the sessions.
Create a CONNECTION resource
with the following attributes:
- CONNECTION(sysidnt)
- NETNAME(name)
- ACCESSMETHOD(VTAM®)
- Note: VTAM is the previous name for z/OS® Communications Server.
- PROTOCOL(LU61)
- DATASTREAM(USER|3270|SCS|STRFIELD|LMS)
- RECORDFORMAT(U|VB)
- QUEUELIMIT(NO|0-9999)
- MAXQTIME(NO|0-9999)
- INSERVICE(YES)
- SECURITYNAME(name)
- ATTACHSEC(LOCAL)
For each session, create a SESSIONS resource with
the following attributes:
- SESSIONS(csdname)
- CONNECTION(sysidnt)
- SESSNAME(name)
- NETNAMEQ(name)
- PROTOCOL(LU61)
- RECEIVECOUNT(1|0)
- SENDCOUNT(0|1)
- SENDSIZE(size)
- RECEIVESIZE(size)
- SESSPRIORITY(number)
- AUTOCONNECT(NO|YES|ALL)
- BUILDCHAIN(YES)
- IOAREALEN(value)
IMS V13 supports connectivity with CICS TS over
IPIC. This offers an alternative to LU6.1 connection for asynchronous
communication. For more information about this interface see
