OSS_REAL_DLL_NOT_LINKED

OSS_REAL_DLL_NOT_LINKED (0x8009301F) is an OSS ASN.1 runtime result for ASN.1 REAL support DLL absent. A Windows modular runtime path requires the component that handles ASN.1 REAL values, but the expected DLL is not loaded. Because REAL fields reached by the operation 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 module filename, version, and architecture, then separate the encoded value from generated artifacts, call arguments, and the runtime package actually loaded by the process.

Interpretation at runtime

At the ASN.1 REAL support DLL absent 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 loader search path and dependency failures; otherwise an outer certificate or security wrapper may hide the useful codec result behind a generic failure.

Diagnostic record

  • REAL fields reached by the operation
  • module filename, version, and architecture
  • loader search path and dependency failures

Small experiments with high signal

  1. round-trip a minimal REAL value after packaging
  2. Inspect the actual loaded path
  3. Test a PDU with no REAL component as isolation

Avoid the wrong workaround: the result

REAL_CODE_NOT_LINKED is the static/generated-code counterpart; this status specifically names the DLL packaging boundary.

Instrumentation

Where REAL fields reached by the operation can expose sensitive content, a hash plus a bounded structural excerpt is safer than the complete payload. Use module filename, version, and architecture together with OSS module paths and versions logged once per process so packaging differences can be correlated without flooding normal diagnostics.

Proof of recovery: the result

Ship the matching REAL module and verify finite, zero, infinity, and protocol-permitted special cases.
