COMADMIN_E_CAT_PARTITION_IN_USE

COMADMIN_E_CAT_PARTITION_IN_USE is the failure HRESULT 0x80110459 (signed decimal -2146368423, unsigned decimal 2148598873). Its severity bit is 1, facility is 17 (FACILITY_ITF), and the facility-specific code field is 0x0459.

COM+ partition administration: exact meaning of COMADMIN_E_CAT_PARTITION_IN_USE

The partition cannot be deleted because one or more users have it as their default partition. Partition deletion checks user-to-default-partition assignments before removing the container.

AllStat records this condition as “The partition cannot be deleted because it is the default partition for one or more users”.

Where COMADMIN_E_CAT_PARTITION_IN_USE 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 COMADMIN_E_CAT_PARTITION_IN_USE, enumerate affected users and partition assignments, including domain identities and stale mappings.

Evidence to collect before repair

Collect partition ID and all default-partition user assignments when diagnosing COMADMIN_E_CAT_PARTITION_IN_USE; without it the symbolic HRESULT is underdetermined.
The COMADMIN_E_CAT_PARTITION_IN_USE investigation needs user SIDs and account resolution status so the exact failing boundary remains reconstructable.
For COMADMIN_E_CAT_PARTITION_IN_USE, preserve planned replacement partition for each user; it anchors the failure to the real administration object.
Evidence for COMADMIN_E_CAT_PARTITION_IN_USE should include activation tests before and after reassignment, captured before a repair changes state.

Diagnostic sequence for COMADMIN_E_CAT_PARTITION_IN_USE

The next COMADMIN_E_CAT_PARTITION_IN_USE diagnostic action is to enumerate every user mapped to the partition.
To isolate COMADMIN_E_CAT_PARTITION_IN_USE, assign each active user to an appropriate surviving default partition.
For COMADMIN_E_CAT_PARTITION_IN_USE, remove or remediate stale mappings carefully.
At the COMADMIN_E_CAT_PARTITION_IN_USE boundary, verify component activation routes to the replacement.
The next COMADMIN_E_CAT_PARTITION_IN_USE diagnostic action is to delete the now-unreferenced partition and repopulate the catalog.

Practical administration scenario

An administrator retires a training partition while several accounts still select it as default.

Retry and recovery

Move each user to an appropriate surviving default partition, verify activation behavior, and then delete.

Difference from nearby COMADMIN results

COMADMIN_E_BASE_PARTITION_ONLY restricts an operation by partition type; this code reports live references preventing deletion.
