IBM Mainframe System Error Codes Quiz

The QSAM GET after end-of-file condition maps to system completion code S001 - 05. This code indicates an attempt to read beyond the dataset's end. Other codes (S001 - 02, 03, 04) represent different QSAM error conditions like dataset close errors or invalid requests.

Dataset close errors under QSAM are indicated by S001 - 02. This is the standard system code for problems encountered while attempting to properly close a QSAM dataset. Other codes map to different QSAM operations.

Invalid RDW (Record Descriptor Word) with length less than 4 for variable-length records maps to S002 - 04. This is a specific validation error where the RDW length field is below the minimum 4-byte threshold. Other codes represent different record format errors.

Record larger than track capacity without track overflow feature during direct dataset creation maps to S002 - 1C. This error occurs when writing oversized records to a dataset that doesn't support track overflow. The 1C suffix indicates this specific write constraint.

Too many tracks specified for cylinder overflow during ISAM dataset open maps to S002 - 2C. This error indicates an invalid cylinder overflow configuration where the track count exceeds limits. The 2C code specifically identifies this overflow allocation error.

DEBCHK failure during PDSE (Partitioned Data Set Extended) processing maps to S002 - 54. This is a specific error code for debugging/check failures encountered while working with PDSE datasets. Other hex variations (55, 56, 57) represent different PDSE-related errors.

Conflicting access methods specified maps to S004 - 03. This system code indicates that incompatible or contradictory access methods were requested for the same dataset operation. Other codes in the S004 series represent different access method errors.

Buffer length of 0 specified for BDAM dataset with dynamic buffering requested maps to S013 - 0C. This error occurs when dynamic buffering is enabled but an invalid (zero) buffer length is provided. The 0C code identifies this specific BDAM buffer configuration error.

Sequential or direct dataset opened for input with buffer control block address of 0 maps to S013 - 40. This error indicates a missing or uninitialized buffer control block (BCB) when the dataset requires one for input operations. The 40 hex code identifies this BCB address error.

Invalid record format of FBS or FS specified for a partitioned dataset maps to S013 - D0. This error occurs when unsupported blocked formats (FBS=Fixed Blocked Standard or FS=Fixed Standard) are used for PDS. The D0 code identifies this format incompatibility.

This is an IBM mainframe system error message where abend code S047 indicates an unauthorized program attempted to access a restricted service. The 'S' prefix denotes a system abend, and '047' is the specific error code for this type of security violation.

In QSAM (Queued Sequential Access Method) on mainframe systems, attempting a GET operation after reaching EOF results in ABEND S001-05. This is a standard system completion code for this specific error condition.

ABEND S001-02 is the standard system completion code for errors encountered while closing a dataset in mainframe environments. This covers various close-related failures like access violations or I/O errors during closure.

The system abend S002 with reason code 04 indicates an invalid record was found on a GET operation where the RDW length is less than 4 bytes (the minimum size of the RDW itself). Other reason codes like 14, 24, and 34 designate different block or record length conflicts.

This describes an IBM mainframe system error code. S002 errors relate to dataset issues, specifically when a write macro attempts a record larger than track capacity without using track overflow. The specific error code S002-1C (option D) corresponds to this exact scenario.

This is another IBM mainframe S002 error code. When opening an ISAM dataset, specifying too many tracks for cylinder overflow triggers error S002-2C (option B). This indicates the dataset's cylinder overflow allocation exceeds system limits.

DEBCHK is a mainframe dataset integrity check utility. When it fails during PDSE (Partitioned Data Set Extended) processing, the specific error code is S002-54 (option A). PDSE is an enhanced format for partitioned datasets on IBM systems.

When conflicting access methods are specified for a dataset operation, the system returns error S004-03 (option D). S004 errors relate to access method violations such as specifying both sequential and direct access simultaneously.
