Holiday Readiness: Best Practices for Sterling Selling and Fulfillment Suite

Answer

• Before the Holiday season, perform a full scale performance testing. Identify a heavy transaction process and fine-tune if necessary.
• Monitor your DB during a full scale performance test and during the pre-holiday season. Work with your DBAs to identify queries that are doing full table, have a high cost or faulty executions plans. DBAs to take curative steps.
• Trim output template of API, userExit, event, or service to keep the data fetched to optimal level.
• Tune the Sterling Reference Caching Mechanism. Refer to performance management guide.
• Configure respective “purges” for all the large transactions. Include “Purge Transaction” in all the Document Type pipelines.
• Check the size of transaction data. If the size of a particular transaction data is high, run purge agents more aggressively (more JVMs, more threads)
• Enable generate heap dump and GC JVM parameter. Refer to JDK (IBM/Sun JDK) documentation.
• Enable agent.bulk.sender.enabled and agent.bulk.sender.batch.size properties. By enabling these properties, messages in your JMS queue are added in bulk, improving the overall performance of the agent
  Sample value:
  yfs.agent.bulk.sender.enabled=true
  yfs.agent.bulk.sender.batch.size=5000
• Also, refer to the Performance must gather page (http://www.ibm.com/support/docview.wss?uid=swg21614185) which helps you to gather required information in case of any performance problems.
