DB_E_RESOURCELOCKED

Exact value and result class

DB_E_RESOURCELOCKED has unsigned value 2147749522 (0x80040E92) and signed 32-bit value -2147217774. AllStat describes it as “OLE DB object represented by this URL is locked by one or more other processes”. In this result, the object represented by the URL is locked by another process or incompatible owner.

The high bit is set, so this result is a failure HRESULT. Its facility is 4 (FACILITY_ITF) and its low code is 3730 (0x0E92). These fields identify an interface-defined result family; they do not identify the provider instance, method, object generation or partial effects.

Evidence to collect

A useful this result event records provider CLSID and version, process architecture, interface IID and method, object correlation ID, transaction state and the immediately preceding HRESULT. When recording it data involving URLs containing credentials, tenant paths and remote object names, use types, lengths, hashes or redacted identifiers rather than secrets or complete business data.

Evidence 1 for it: normalized URL and requested access mode.
Evidence 2 for it: lock owner or lease metadata when available.
Evidence 3 for it: open handles and process lifetime around the resource.

Contract boundary

The OLE DB binder model maps URLs to row, rowset, stream or collection objects. URL scope, requested object type, bind flags, asynchronous capability, locks and server reachability are independent parts of the binding contract.

Investigation of this result should start with the binder or session, normalized URL, requested GUID/object type and DBBINDURLSTATUS result. Capture it before ADO, ATL,.NET or a database abstraction layer replaces the native HRESULT with a generic exception.

Conditions that specifically lead to it

Cause 1 for it: another writer holds an exclusive resource lock.
Cause 2 for it: a stale process still owns an open row or stream.
Cause 3 for it: the provider maps a server-side lease or checkout to the URL.

Diagnostic sequence

Capture raw 0x80040E92 and symbolic it at the native call boundary.
Identify the exact failing stage for it: the object represented by the URL is locked by another process or incompatible owner.
Retrieve all OLE DB error records for it before another COM call replaces thread error information.
Compare the live object state and provider-granted capabilities with the input that produced it.
Reduce the operation to the smallest case that preserves the same binder contract.
Apply one evidence-backed correction for it and verify that the result is not merely replaced by a neighboring HRESULT.

Corrective actions

Action 1 for it: release local objects before assuming an external conflict.
Action 2 for it: coordinate through provider locking or checkout APIs.
Action 3 for it: use bounded backoff only when lock ownership is transient.

Practical scenario

An editor crashes while holding a provider lease; lease expiry and state refresh allow a later write to proceed. Keeping it with the method and object state makes this scenario diagnosable instead of reducing it to “database error”.

Developer and operations guidance

Code handling it should release COM objects in ownership order, retain per-row, per-column or per-property statuses, and log granted capabilities rather than only requested options. While handling it, opaque values such as HACCESSOR, HROW, HCHAPTER, DBID components and provider handles must remain scoped to the object that issued them.

Operational dashboards for it should group by provider version, interface, method and normalized failure stage. A it event must not expose passwords, tokens, full connection strings, unrestricted command text or raw row contents.

Retry and recovery

Retry rule for it: retry after the conflicting lock has been released and the resource generation revalidated. A it retry is safe only when the relevant input, object generation, capability or external state has changed. Before replaying a modifying call that returned it, determine whether rows, schema objects or URL resources were partially created or changed.

Do not turn it into an unbounded retry loop. Preserve cancellation for it and use a fresh provider object when the failed call may have left local state ambiguous.

Difference from nearby HRESULT values

DB_E_READONLY means the object cannot be written by contract, while it means current lock state prevents access. Telemetry and remediation for it should keep these outcomes distinct.
