“TPIGNORE” stands for “ignore error on tape” and refers to the right of the user (or of the user ID) to ignore error messages issued by the label processing routines.
If (s)he is recorded in the HDR3 label as the owner, the file owner can ignore all such error messages or even bypass label checking (SECLEV operand in the FILE/FCB macro; PROTECTION-LEVEL operand in the ADD-FILE-LINK command). Users wishing to access “foreign” tape files can ignore error messages or bypass label checking only if systems support has granted them the appropriate TAPE-ACCESS authorization. This authorization is registered in the field TAPE-ACCESS in the user catalog. The user can obtain information on the entries in the user catalog for his/her user ID with the SHOW-USER-ATTRIBUTES command.
The following table shows the various levels of the TAPE-ACCESS authorization.
TAPE-ACCESS value | Meaning |
|---|---|
STD | The user is not authorized to ignore error messages. |
PRIVILEGED | The user may ignore error messages; in batch mode, DMS suppresses certain messages if PROTECTION-LEVEL=LOW applies; if PROTECTION-LEVEL=HIGH is set, the operator must decide whether the error may be ignored(ADD-FILE-LINK command, PROTECTION-LEVEL operand). |
READ | The user may ignore error messages which refer to input files; label checking is not deactivated. |
BYPASS-LABEL | The user may bypass label checking and/or ignore error messages for input files. |
ALL | The user may bypass label checking and/or ignore all error messages. |
Messages concerning the mounting of tapes or checking of volume labels are sent to the operator. The operator then decides how tape processing is to proceed. Messages concerning the checking of file labels are sent to the user or to the calling job. The user can then activate suitable error routines in his program.
The TAPE-ACCESS authorization also affects BYPASS handling.
