Chapter 10 Accessing and Processing VSAM LDS Data : Operations for Processing Data

Operations for Processing Data
You process the data using the TIBCO Object Service Broker rules language. Access to the VSAM LDS returns the address of the data buffer that can be manipulated using an associated VSAM MAP table.
Supported Operations
Only the GET, INSERT and REPLACE operations with fully qualified primary keys (the relative byte address of the record) are supported. Samples are shown in VSAM LDS Samples.
See Also
TIBCO Object Service Broker Programming in Rules for detailed information about processing data using the TIBCO Object Service Broker rules language.
Insert Processing
To commence INSERT processing if no previous GET accesses have been performed the address of the buffer in the interface needs to be obtained. This is achieved by accessing the VSAM LDS with a special key of -1:
GET vsamlds_table WHERE RBA=-1;
This access returns the address of the processing buffer in the VSAM LDS interface. You can then use VSAM MAP table processing to manipulate this buffer.
