This method opens a given workspace and specifies whether to read and write to the MM_SYSTEM_PERSIST_INFO table or the MM_PERSIST_INFO table. Most users don't have access to the MM_SYSTEM_PERSIST_INFO table. If the parameter is set to false, the login user name is used to read and write to the MM_PERSIST_INFO table.
