Problem: You receive the error message "RLV dbspace already exists. Cannot create more than one RLV dbspace".
A row-level versioning (RLV) dbspace exists on the database. SAP Sybase IQ only supports one RLV dbspace per simplex database.
You could encounter this error while trying to increase the size of the RLV dbspace. If so, instead of trying to create another RLV dbspace, add a new dbfile to the existing RLV dbspace.
