Purpose

Conveys the current length of the input (response) buffer.

Usage Notes

The ExtendedKeepResponse parcel requests as many response parcels as will fit in the specified MaxMsgSize.

If the ExtendedKeepResponse parcel is used in a start request or continue request and the start response or continue response contains the EndRequest parcel, the spool file is retained on the database.

In general, the spool file is deleted in any of the following situations:
  • A Cancel parcel is issued
  • The EndRequest parcel is returned in response to a continue request that contained a Response parcel
  • An abort operation occurs
  • A logoff operation occurs

This parcel is generated by CLIv2 at the direction of the application.

Field Notes

MaxMsgSize is the maximum number of bytes that can be returned to the client in one response. The minimum allowable buffer size is 256 bytes, hence MaxMsgSize must be greater than or equal to 256. The maximum value is 4294967295.
