COMADMIN_E_BASE_PARTITION_ONLY
COM+ partition administration: exact meaning of COMADMIN_E_BASE_PARTITION_ONLY
The requested function is valid only in the COM+ base partition. ICOMAdminCatalog2 or related administration resolves a non-base partition for an operation restricted to machine-global configuration.
Windows describes this condition as “This function is valid for the base partition only”.
Where the result occurs
Partitions are logical containers with explicit IDs, names, user defaults, application contents, and platform enablement; operations must use the intended partition rather than assume a global namespace. In the specific case of this result, record partition ID, default/base status, target application, and the exact administration method.
Evidence to collect before repair
- Preserve partition ID, partition name, and base/default status; it anchors the failure to the real administration object.
- Evidence should include the ICOMAdminCatalog2 method and target object, captured before a repair changes state.
- Collect current application AppID and partition membership when diagnosing this result; without it the symbolic HRESULT is underdetermined.
- Record the caller’s partition-selection logic.
Diagnostic sequence
- enumerate partitions and identify the base partition ID.
- separate machine-global operations from tenant-partition operations.
- The next diagnostic action is to invoke the function against the base partition explicitly.
- To isolate this result, return to the intended partition for application-level work.
- Verify no cross-partition configuration was changed.
Retry and recovery
Switch to the base partition for the operation or use a partition-aware alternative documented for local partitions.
Difference from nearby COMADMIN results
COMADMIN_E_CAT_IMPORTED_COMPONENTS_NOT_ALLOWED concerns package contents in a non-base partition, not a base-only method.
Practical administration scenario
Automation runs a machine-level catalog operation while connected to a tenant-specific partition.
