```
Relational Database Name specifies the name of a relational database of the server. if length of RDB name <= 18 characters, there is not change to the format of the RDB name. The length of the RDBNAM remains fixed at 18 which includes any right bland padding if necessary. if length of the RDB name is > 18 characters, the length of the RDB name is identical to the length of the RDB name. No right blank padding is required.

Parameters:

rdbnam - name of the database.

dontSendOnConversionError - omit sending the RDBNAM if there is an exception converting to EBCDIC. This will be used by ACCSEC to defer sending the RDBNAM to SECCHK if it can't be converted.
