Informix Error -32159: The mapping tag does not exist in system.

Reasons / Common Causes

A tag in label.map has no corresponding entry on the tape, per the official guidance — the direct, only cause.

Solutions / Resolution

Only provide mapping for tags that are actually present on the tape, per the official guidance.

Examples

N/A

No specific triggering statement is documented beyond a label.map tag missing from the tape.
