Parallel query execution infrastructure

The database server creates and maintains various database objects to manage the execution of spatial queries in parallel.

Do not alter or delete any of the following items of infrastructure:
  • The SE_MetadataTable table.
  • The SE_Metadata opaque type.
  • The metadata smart large object, which is stored in the default sbspace.
  • The metadata lohandle file.
  • The metadata memory cache.
  • Triggers on the spatial_references table

You can use the SE_MetadataInit() function to re-initialize this infrastructure in case of difficulty.
