3Snapshot user-defined functions (UDF) are intended to be used on 3databases whose Directory entry type value displays as Indirect or 3Home when the LIST DB DIRECTORY command is issued. If a UDF is used 3against a remote database, the UDF will fail and the following error message 3will display:
3 SQL1427N An instance attachment does not exist.
4The snapshot UDFs, introduced in V8.1 cannot be used in 4conjunction with the monitor switches commands and APIs or monitor reset 4commands and APIs. This restriction includes: 4
4This limitation occurs because such commands use an INSTANCE ATTACH, while 4the snapshot UDFs make use of DATABASE CONNECTs.
