Expression-Field Functions That Support CREATEBICI Processing

Expression-Field Functions That Support CREATEBICI Processing

If you specify user-defined fields with expressions that are associated with PowerExchange functions in the CREATEBICI parameter, ensure that the fields are associated with functions that support before-image (BI) buffering. If the functions do not support BI buffering, the DTLUCBRG utility does not create the BI and CI columns.
The following table lists functions that support BI buffering for Adabas, IDMS, IMS, i5/OS sequential, and VSAM ESDS and RRDS data sources:
Function
Returns
GetDatabaseKey
Database key for a record or a segment.
GetDBKey
Alias for GetDatabaseKey.
The following table lists functions that support BI buffering for IDMS sources only:
Function
Returns
GetDbKeyOfFirstMember
Database key of the first member of the specified set.
GetDbKeyOfLastMember
Database key of the last member of the specified set.
GetDbKeyOfNextMember
Database key of the next member record of the specified set.
GetDbKeyOfOwner
Database key of the owner of an IDMS set name.
GetDbKeyOfPriorMember
Database key of the previous member record of a specified set.
GetFullDbKey
Fully qualified database key of an IDMS record, which includes the 4-byte concatenated page group and radix identifier prefix.
GetFullDbKeyOfFirstMember
Fully qualified database key of the first member of the specified set, which includes the 4-byte concatenated page group and radix identifier prefix.
GetFullDbKeyOfLastMember
Fully qualified database key of the last member of the specified set, which includes the 4-byte concatenated page group and radix identifier prefix.
GetFullDbKeyOfNextMember
Fully qualified database key of the next member of the specified set, which includes the 4-byte concatenated page group and radix identifier prefix.
GetFullDbKeyOfOwner
Fully qualified database key of the owner of an IDMS owner record, which includes the 4-byte concatenated page group and radix identifier prefix.
GetFullDbKeyOfPriorMember
Fully qualified database key of the previous member of the specified set, which includes the 4-byte concatenated page group and radix identifier prefix.
