IST/Switch Overview

IST/Switch maintains a log of all transactions that have been processed by the system and stores the details in the Transaction Log table - SHCLOG.

A copy of iristtlr will be spawned for each SHCLOG table in the IST environment. Iristtlr will read transactions from this table and send them to the Transaction Surveillance (irtsvcol) or Transaction Manager (irtxncol) collectors. These will be delivered as TransactionDetail, TransactionException, IstPosTransactionSummary or IstAtmTransactionSummary records to the rest of Transact. The access credentials for the relevant database(s) need to be configured within the IST configuration (for Transaction Manager) or irtsvcol.ini (for Transaction Surveillance).
