DETAILS OF INCIDENTS FIXED BY THE PATCH --------------------------------------- This patch fixes the following incidents: Patch ID: 7.1.000.100 * 3910566 (Tracking ID: 3892025) SYMPTOM: The CP Server logs errors about operation failures when multiple clients of CP server run similar commands in parallel. These operation errors are flagged as CRITICAL. DESCRIPTION: When clients of CP servers run multiple commands in parallel, sometimes, such operations return the value SQLITE_BUSY to the client. The operation returns SQLITE_BUSY, because another operation has locked the database. In such case where operation fails due to database lock being busy the server does not retry these commands. RESOLUTION: The VxCPS program is modified to handle a SQLITE_BUSY value and the program retries the operation on the server.
