We divide the scan into a scan on each fragment. The scan uses the primary replicas since the scan might be used for an update in a separate transaction. Scans are always done as a separate transaction. Locks from the scan can be overtaken by another transaction. Scans can never lock the entire table. Locks are released immediately after the read has been verified by the application. There is not even an option to leave the locks. The reason is that this would hurt real-time behaviour too much. -# The first step in handling a scan of a table is to receive all signals defining the scan. If failures occur during this step we release all resource and reply with SCAN_TABREF providing the error code. If system load is too high, the request will not be allowed. -# The second step retrieves the number of fragments that exist in the table. It also ensures that the table actually exist. After this, the scan is ready to be parallelised. The idea is that the receiving process (hereafter called delivery process) will start up a number of scan processes. Each of these scan processes will independently scan one fragment at a time. The delivery process object is the scan record and the scan process object is the scan fragment record plus the scan operation record. -# The third step is thus performed in parallel. In the third step each scan process retrieves the primary replica of the fragment it will scan. Then it starts the scan as soon as the load on that node permits. The LQH returns either when it retrieved the maximum number of tuples or when it has retrived at least one tuple and is hindered by a lock to retrieve the next tuple. This is to ensure that a scan process never can be involved in a deadlock situation. When the scan process receives a number of tuples to report to the application it checks the state of the delivery process. Only one delivery at a time is handled by the application. Thus if the delivery process has already sent a number of tuples to the application this set of tuples are queued. When the application requests the next set of tuples it is immediately delivered if any are queued, otherwise it waits for the next scan process that is ready to deliver. ERROR HANDLING As already mentioned it is rather easy to handle errors before the scan processes have started. In this case it is enough to release the resources and send SCAN_TAB_REF. If an error occurs in any of the scan processes then we have to stop all scan processes. We do however only stop the delivery process and ask the api to order us to close the scan. The reason is that we can easily enter into difficult timing problems since the application and this block is out of synch we will thus always start by report the error to the application and wait for a close request. This error report uses the SCAN_TABREF signal with a special error code that the api must check for. CLOSING AN ACTIVE SCAN The application can close a scan for several reasons before it is completed. One reason was mentioned above where an error in a scan process led to a request to close the scan. Another reason could simply be that the application found what it looked for and is thus not interested in the rest of the scan. IT COULD ALSO BE DEPENDENT ON INTERNAL ERRORS IN THE API. When a close scan request is received, all scan processes are stopped and all resources belonging to those scan processes are released. Stopping the scan processes most often includes communication with an LQH where the local scan is controlled. Finally all resources belonging to the scan is released and the SCAN_TABCONF is sent with an indication of that the scan is closed. CLOSING A COMPLETED SCAN When all scan processes are completed then a report is sent to the application which indicates that no more tuples can be fetched. The application will send a close scan and the same action as when closing an active scan is performed. In this case it will of course not find any active scan processes. It will even find all scan processes already released. The reason for requiring the api to close the scan is the same as above. It is to avoid any timing problems due to that the api and this block is out of synch. * ######################################################################## */ void Dbtc::execSCAN_TABREQ(Signal* signal) { const ScanTabReq * const scanTabReq = (ScanTabReq *)&signal->theData[0]; const Uint32 reqinfo = scanTabReq->requestInfo; const Uint32 aiLength = (scanTabReq->attrLenKeyLen & 0xFFFF); const Uint32 keyLen = scanTabReq->attrLenKeyLen >> 16; const Uint32 schemaVersion = scanTabReq->tableSchemaVersion; const Uint32 transid1 = scanTabReq->transId1; const Uint32 transid2 = scanTabReq->transId2; const Uint32 tmpXX = scanTabReq->buddyConPtr; const Uint32 buddyPtr = (tmpXX == 0xFFFFFFFF ?
