The Oracle Tuxedo Mainframe Adapter for SNA translation tables are based on IBM-defined code sets. At start up, the Gateway loads a translation table for each remote domain.

You can modify any of the tables to suit your application translation needs, except the default ATMI tables, which are hard-coded. Refer to Appendix C, Code Page Translation Tables for detailed table contents. You must restart the Gateway to change any translation table definitions.

The Oracle Tuxedo Mainframe Adapter for SNA translation tables are located in the following sub-directory:

$TUXDIR/udataobj/codepage

If no CODEPAGE specification is made for a remote domain, the Oracle Tuxedo Mainframe Adapter for SNA software uses the ATMI default translation tables. If the software cannot find the translation table file, it generates a message 2241:ERROR Unable to access codepage table with a reason code and the Gateway fails to start. Refer to this message in Appendix B, Error Messages for explanations of the reason codes.

The following listing depicts entries defining one local domain (CIXA) and two remote domains (CISA and IMSA). In all cases, the assumption is made that the local domain uses ASCII code page CP-00819. In the example, the two remote domains use the German and French EBCDIC code pages CP-00273 and CP-00297, respectively.
