COMPATIBILITY NO_CHKMBRNAMLEN
The length of a c-tree Superfile name is restricted because the Superfile directory index has a restricted key length. A default behavior checks when the Superfile member name is restricted due to small page sizes: if the Superfile name is truncated in the Superfile member directory index, then the create of the member will fail with SNAM_ERR (418). Without this new behavior, member names that would be truncated to the same string would cause DOPN_ERR (19) and/or KOPN_ERR (18) errors.
To address the situation where names may have been truncated but no conflicts arose and would now get error SNAM_ERR at create time, COMPATIBILITY NO_CHKMBRNAMLEN is available to revert to the original behavior.
