Serial transaction processing in an MSC network
Serial transactions are processed in the order they are received in relative to other transactions of the same type.
You can ensure serial processing of transactions in remote MSC IMS systems by taking the following steps:
- Define the transaction as serial in both the local and remote MSC IMS systems.
- Restrict the transactions to a single logical link path between the local and remote MSC IMS systems.
- Send all serial transactions of the same type to the same remote MSC IMS for processing.
- Are sent across different logical link paths
- Originate from different MSC IMS systems
- Are processed in different remote MSC IMS systems
The PRTY= keyword and output messages of serial transactions in an MSC network
The serial processing of the output messages of a serial transaction can become unpredictable in an MSC network if the normal and limit parameters of the priority (defined by the CREATE TRAN SET(NPRI(normalpriority),LPRI(limitpriority)) or the TRANSACT macro PRTY= keyword) are not equal.
If the normal and limit parameters are not equal and the number of output messages on a message queue becomes equal to or greater than the value of the limit_count parameter of the PRTY= keyword, output messages received by a remote MSC IMS system after the limit_count value has been reached might be processed before messages received by the remote MSC IMS system.
