• Adabas field data types are translated to the TIBCO Object Service Broker field types defined in the ADA table.The following sections describe the mechanisms available to process the data, how to take advantage of Adabas functionality, and how to handle errors.When Adabas data is requested, a server starts a FORALL. Data is sent to the Data Object Broker in variable length buffers up to a maximum of 31 KB, as shown in the following figure. If a single request requires more than 31 KB of data, multiple 31 KB buffers are sent and processed until the request is complete.Processing Adabas data through TIBCO Object Service Broker is subject to the following limitations:
• TIBCO Object Service Broker Adabas must be initialized by a standard ADALNK module that is identical to that provided by Software AG.
• TIBCO Object Service Broker has no direct equivalent to the Natural statements HISTOGRAM or FIND UNIQUE. Therefore TIBCO Object Service Broker does not issue the Adabas commands L9, S1, or RC. Using TIBCO Object Service Broker rules to manipulate the returned data can enable the same functionality.
• TIBCO Object Service Broker table definitions for Adabas fields are based solely on the FDT. Therefore Predict and Natural long field names as defined in the DDM must be entered manually.
