JR44499: CMVC 224622 - TO FIX THE INVENTORY CACHE EXPIRY PROBLEM CAUSED BY THE INT OVERFLOW OF COMPOSEDOMINVENTORYAVAILABILITYCMDIMPL

7.0.0-WS-WCServer-FP009

APAR status

• Closed as program error.

Error description

• When the customer changes the store default inventory cache
  expiration to above or below the threshold, for example, to
  every 30 days( 2925000 seconds),  the configuration won't be
  respected. Instead, every cache item expires instantly no matter
  what the last update time is.
  
  This is because in the ComposeDOMInventoryAvailabilityCmdImpl,
  there is an int overflow problem. If we set for expiration
  threshold more than 2147483647 ms (around 24.85 days), the cache
  will expire instantly.
  

Local fix

• The customer can set the expiration threshold to less than
  2147483647 ms(around 24.85 days).
  

Problem summary

• USERS AFFECTED:
  WebSphere Commerce users on v7.0 who use the inventory cache
  expiration.
  
  PROBLEM ABSTRACT:
  The inventory cache expiry threshold not working as expected due
  to int overflow.
  
  BUSINESS IMPACT:
  The cache mechanism is not working as expected and will impact
  the performance.
  
  RECOMMENDATION:
  

Problem conclusion

• The code change will fix the int overflow issue so that the
  inventory cache expiry threshold will work properly.
  The change is made to
  com.ibm.commerce.inventory.facade.server.commands.ComposeDOMInve
  ntoryAvailabilityCmdImpl, change
        private static final int THOUSAND = 1000;
       to
        private static final long THOUSAND = 1000;
