APAR status
Closed as program error.
Error description
Setting a TTL programmatically of more than 6442450 seconds causes a IllegalArgumentException. This error occurs when using eXtremeMemory (XM) before 8.6.1.1 and occurs for all configuration when using 8.6.1.1 and 8.6.1.2. Below shows an FFDC stack trace on the server side for this problem. Exception:java.lang.IllegalArgumentException SourceId:com.ibm.ws.objectgrid.server.impl.ServerCoreEventProces sor.processLogSequence ProbeId:1016 java.lang.IllegalArgumentException: Time to live value must be greater than or equal to -1 at com.ibm.ws.objectgrid.ObjectMapImpl.setTimeToLive(ObjectMapImpl. java:1374)
Local fix
Set the large TTL in the objectGrid.xml. The issue only occurs when setting the TTL programmatically.
Problem summary
**************************************************************** * USERS AFFECTED: Users of eXtreme Scale who use the time to * * live function with a large time to live * * value when using ObjectMap.setTimeToLive * * (). * **************************************************************** * PROBLEM DESCRIPTION: Transactions fail with an * * IllegalArgumentException exception or * * entries evict immediately when they * * should evict weeks later. * **************************************************************** * RECOMMENDATION: * **************************************************************** The calculation of the expiration time for entries was incorrect. With the introduction of millisecond precision in 8.6.1.1 for JCache function, the number of maximum seconds was reduce to Integer.MAX_VALUE / 1000 which is what prevented the user from having a large time to live setting. The function was updated to correctly calculate the expiration time with large time to live values and the logic was updated to round to seconds if a milliseconds value was larger than Integer.MAX_VALUE to support larger time to live values.
Problem conclusion
An interim fix is available for this APAR upon request for eXtreme Scale versions 8.6.0.8 and 8.6.1.2.
