COMADMIN_E_CAT_INVALID_PARTITION_NAME
COM+ partition administration: exact meaning of COMADMIN_E_CAT_INVALID_PARTITION_NAME
The proposed COM+ partition name is invalid or contains no visible character. Partition property validation rejects the name before catalog creation or rename.
Windows describes this condition as “The specified partition name is invalid. Check that the name contains at least one visible character”.
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, log the exact Unicode value, trimming/normalization, control characters, and source template.
Evidence to collect before repair
- Collect the exact Unicode code points of the proposed name when diagnosing this result; without it the symbolic HRESULT is underdetermined.
- Record trimmed and normalized representations.
- Preserve configuration variable expansion source; it anchors the failure to the real administration object.
- Evidence should include the method/property receiving the name, captured before a repair changes state.
Diagnostic sequence
- The next diagnostic action is to reject empty and whitespace-only values before COMAdmin.
- To isolate it, remove control characters while preserving intended visible text.
- Separate partition ID, description, and name fields.
- submit a concise visible name.
- The next diagnostic action is to repopulate partitions and verify the stored name.
Practical administration scenario
A configuration variable expands to whitespace and is passed as the new partition name.
Retry and recovery
Provide a stable visible name and validate it before calling the catalog API.
Difference from nearby COMADMIN results
COMADMIN_E_CAT_DUPLICATE_PARTITION_NAME accepts the syntax but finds a collision.
