In this release, a code page conversion table is not normally
required for CICS® Web support. However, if you have existing
request processing structures that include an analyzer program which
references entries in the conversion table, and you do not want to
change the analyzer program, you can continue to provide DFHCNV entries.
In releases of CICS before CICS Transaction Server for z/OS®, Version 3 Release 1,
the code page conversion table (DFHCNV) was used to define code page
conversions between the code pages used within CICS,
and the ASCII code pages used by Web clients. For CICS Web
support in CICS Transaction Server for z/OS, Version 3 Release 1,
you do not need to create any new entries in the code page conversion
table. CICS Web support handles code page conversion
using z/OS conversion services.
However, if
you want to continue to use an analyzer program that you coded in
an earlier CICS release to reference DFHCNV, you must either
continue to supply the entries in the code page conversion table,
or change the analyzer program. Changing the analyzer program involves
coding two new output parameters to specify the client and server
code pages, in place of the output parameter that specified the name
of a DFHCNV entry. If you do this, you do not need to migrate your
DFHCNV entries.
Writing an analyzer program tells you
how to code your output parameters in this way.
Note: As supplied,
the CICS-supplied sample analyzer DFHWBADX specifies an entry defined
in the sample code page conversion table DFHCNVW$. The sample conversion
table can be used without any configuration, but you might prefer
to modify DFHWBADX to use the new output parameters, to provide greater
control and avoid the use of the sample conversion table.
If
you prefer to continue using DFHCNV, follow these steps:
