IDS_MON_VIEW_ALREADY_DEFINED

IDS_MON_VIEW_ALREADY_DEFINED indicates duplicate schema creation. The provider has already registered the view in the target catalog, so repeating the definition is not equivalent to opening or querying that view.

Make catalog initialization state-aware

  • Log the target catalog and view name and identify which installation or startup path created it first.
  • Check for parallel initialization, retry logic that repeats a successful DDL-like operation, or version upgrades that do not detect the existing schema.
  • Do not delete the search catalog merely to clear the name unless the deployment intentionally rebuilds all schema and indexed state.

Microsoft lists this as a parser/schema error in the legacy Indexing Service query family. Modern Windows Search SQL does not use application-defined views in its normal SystemIndex query form. Seeing this code in maintained software is therefore also a useful signal to inspect whether legacy catalog initialization is still being run on a system that should use the Windows Search property model.
