The Consumer can now be configured to pad an Enscribe TARGETFILE

record in the event an update audit trail event record length is shorter than

the target record length as defined when the file was created (i.e., the

Consumer uses the file label record length to determine the target record

length and its padding).

T he DBS object parameter EXTENDUPDATE (used for updates) was

added to define the character to be used for padding the target record.

The parameter value is specified as a decimal number (0 through 255)

representing an ASCII character. For example, the value 32 would be

used to have the target padded with “ “ (space character). The value 88

would be used to have the uppercase “X” character used for padding.

The default value is OFF, meaning that the original source record length is

used for the target record length for the update event.

The EXTENDUPDATE DBS parameter is useful when the target Enscribe

file definition does not match the source, or when you want to make sure

all records written into a target file are of the same length (to match the

file’s defined length). When enabled, a shorter or update event will be

padded out to the file’s defined record length using the pad character.

Note: That a DBS TARGETREC DDL definition and the initialization

associated with the field definitions for the record layout take

precedence over EXTENDUPATE. That is, when a TARGETREC

parameter is specified and a short record is being processed, the

target record length is derived from the specified record definition

and initialized based upon the DDL field definition types (e.g.,

character fields are padded with spaces; binary integers are

padded with binary zeros, etc).

The following are examples of setting the parameter.

SET DBS EXTENDUPDATE OFF

SET DBS EXTENDUPDATE <decimal number>
