OSS_TABLE_MISMATCH
OSS_TABLE_MISMATCH (0x8009301D) is an OSS ASN.1 runtime result for requested type absent from the active control table. The type being encoded is not defined by the generated table attached to the current runtime context. Because symbolic type and numeric selector is central to this condition, Microsoft’s HRESULT range and the OSS Nokalva return-code documentation should be read together. Start the investigation by recording schema module used to generate the table, then separate the encoded value from generated artifacts, call arguments, and the runtime package actually loaded by the process.
Locate the failing codec stage
At the requested type absent from the active control table boundary, capture the first OSS function returning the value and note whether the operation was encode, decode, copy, compare, constraint validation, or trace setup. Preserve the selected PDU, encoding rules, and control table identity chosen at runtime; otherwise an outer certificate or security wrapper may hide the useful codec result behind a generic failure.
Evidence worth preserving
- symbolic type and numeric selector
- schema module used to generate the table
- control table identity chosen at runtime
A controlled way to reproduce it
- encode a type known to exist in that table
- Compare generated headers with the loaded control artifact
- look for cross-module context reuse
What not to confuse it with: the result
PDU_RANGE rejects a selector outside the top-level range; TABLE_MISMATCH often exposes a valid application type paired with the wrong generated table.
Instrumentation
Where symbolic type and numeric selector can expose sensitive content, a hash plus a bounded structural excerpt is safer than the complete payload. Use schema module used to generate the table together with OSS module paths and versions logged once per process so packaging differences can be correlated without flooding normal diagnostics.
Exit criteria: the result
Route each generated value to its matching control context and deploy schema artifacts atomically.
