System-coded character set identifiers
To support character conversion, the IBM® Distributed Relational Database Architecture™ (DRDA) uses CCSIDs to label the various character representation schemes.
The CCSID is a two-byte binary number that uniquely identifies one or more pairs of character sets and code pages. The coded character set defines how bit configurations are mapped for character data.
The CCSID of character strings at your site is determined by the CCSID that you specify on installation panel DSNTIPF.
The correct CCSID is the number that identifies the coded character set that is supported by your I/O devices, local applications such as IMS and QMF, and remote applications such as CICS® Transaction Server.
Attention: If this CCSID is not correct, character conversion produces incorrect
results.
