The default client or server code pages can be defined in the system initialization table in order to reduce the number of conversion tables required to configure a CICSplex.
Whenever data is passed between CICS® and another system, some or all of the data may have to be converted from ASCII to EBCDIC format, or vice versa. Data conversion is facilitated by the DFHCNV conversion table, which contains a conversion template for each resource for which conversion is required.
Certain distributed components of a CICSplex such as CICS Transaction Gateway for z/OS® and CICS Transaction Server for Windows do not provide an override for the default client code page specified in the conversion table. Because conversion tables do not have a suffix, two tables can be required, each residing on a different library and differing only in the default code page.
In order to reduce the number of conversion tables required, you can now specify that the default client or server code page is defined in the system initialization table.
