Typically, the KeepResp parcel conveys the current length of the input (response) buffer.
- A Cancel parcel is issued in a (dis)continue request,
- The EndRequest parcel is returned in response to a continue request that contained a Resp parcel,
- An abort operation occurs, or
- A logoff operation occurs.
This parcel is generated by CLI at the direction of the application.
The following table lists field information for the KeepResp parcel.
|Flavor Field||Parcel Body Length||Parcel Body Fields|
|5||6||MaxMsgSize: 2 byte integer|
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. Also, MaxMsgSize must be less than or equal to the size of the input (response) buffer. If the next parcel to be returned by the database is larger than MaxMsgSize, an Error parcel that specifies how large the buffer must be is returned. If the buffer size is too small, a larger buffer must be allocated by the application program.
