OSS_OID_DLL_NOT_LINKED
OSS_OID_DLL_NOT_LINKED (0x8009301A) is an OSS ASN.1 runtime result for OBJECT IDENTIFIER support module absent. The legacy modular runtime attempts an OID-specific operation but the DLL that implements it is not available to the process. Because loaded module list and search path 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 architecture and version of the OID component, then separate the encoded value from generated artifacts, call arguments, and the runtime package actually loaded by the process.
What the return code narrows down
At the OBJECT IDENTIFIER support module 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 PDU fields that require OBJECT IDENTIFIER handling; otherwise an outer certificate or security wrapper may hide the useful codec result behind a generic failure.
Test one variable at a time
- encode a PDU without OID fields as a control
- inspect loader failure with dependency tools
- package the module beside the matching runtime
Build a useful capture
| Record | Diagnostic value |
|---|---|
| loaded module list and search path | Locates the concrete message, allocation, module, or API boundary |
| architecture and version of the OID component | Separates payload-dependent behavior from build and process state |
| PDU fields that require OBJECT IDENTIFIER handling | Makes the comparison reproducible without rewriting the original artifact |
Neighboring statuses: the result
Changing an OID value will not repair a missing binary; validate data only after dependency loading succeeds.
Keep the original bytes or object graph unchanged while testing encode a PDU without OID fields as a control. A change in architecture and version of the OID component after reload, plugin replacement, restart, or schema deployment is evidence about runtime state, not permission to discard the reproducer. When PDU fields that require OBJECT IDENTIFIER handling points to one message, retain a cryptographic hash and the smallest safe sample instead of logging certificate, subscriber, credential, or private-key material.
Instrumentation
Record the full 32-bit HRESULT and lower OSS return number together with operation direction, symbolic PDU, encoding rule, byte count, and generated-table identifier. Where loaded module list and search path can expose sensitive content, a hash plus a bounded structural excerpt is safer than the complete payload. Use architecture and version of the OID component together with OSS module paths and versions logged once per process so packaging differences can be correlated without flooding normal diagnostics.
Decision matrix
| Controlled observation | Conclusion it supports |
|---|---|
| encode a PDU without OID fields as a control | A changed outcome isolates the first proposed control instead of a blind retry |
| loaded module list and search path differs between success and failure | The difference localizes the OBJECT IDENTIFIER support module absent boundary before unrelated settings are changed |
| An independent decoder accepts the same artifact | Inspect generated schema, selected rules, ABI, and optional OSS modules before declaring the bytes invalid |
| A fresh control object changes the outcome | Investigate initialization, lifecycle, allocator ownership, configuration mutation, and concurrent access |
Verify the repair: the result
Deploy the matching OID module or rebuild with the required support statically linked, then round-trip representative identifiers. A recovery test built around encode a PDU without OID fields as a control should replay the same operation under the same schema and encoding rule, retain one deliberately invalid control, and verify ownership and cleanup after both outcomes. Success after an unexamined retry is not proof that loaded module list and search path now satisfies the codec contract.
