Dynamic prepare on jConnect caches

Ensure that connection caches that utilize a com.sybase driver class are defined with the DYNAMIC_PREPARE property set to FALSE for optimal performance. In EAServer 4.1.1 and later, this property is set to FALSE by default. However, it was set to TRUE by default in some earlier versions. In EAServer 4.1.1 and later, a warning is printed in the log file if a connection cache has this property set to TRUE.
