You can now drop a DB2 Data Links Manager for a specified database. The processing of some Data Links-related SQL requests, as well as utilities, such as backup/restore, involve communicating with all DLMs configured to a database. Previously, DB2 did not have the capability to drop a configured DLM even though it may have not been operational. This resulted in an additional overhead in SQL and utilities processing. Once a DLM was added, the engine communicated with it in the processing of requests, which may have resulted in the failure of some SQL requests (for example, drop table/tablespace/database).
