ECIXAResourceAdapter V7.1.0.2 and ECIResourceAdapter V7.1.0.2
support CICS® Container applications.
Containers are named blocks of data designed for passing information
between programs. You can think of them as /named communication areas
(COMMAREAs). Programs can pass any number of containers between each
other. Containers are grouped in sets called channels; a channel is
analogous to a parameter list.
Container support
In the past, CICS application programs use communication
area COMMAREA to exchange data. The new CICS Channel support enhances how data is transferred between
programs. Here are some of the benefits of Channel/Container model
over COMMAREA:
- Unlike COMMAREA, channels are not limited in size to 32 KB.
There is no limit to the number of containers that can be added to
a channel, and the size of individual containers is limited only
by the amount of storage that you have available.
- Because a channel can comprise multiple containers, it can be
used to pass data in a more structured way. In contrast, a COMMAREA
is a monolithic block of data.
- Unlike COMMAREAs, channels do no't require the programs that use
them to know the exact size of the data returned.
