DynaCache invalidation processing can take several milliseconds to complete in each application server node JVM where stale cached information may need to be removed. It is possible that two URL requests sent to two different servers, where the first request makes a change to the database and issues dynacache invalidations, which are sent to the second server, and the second request is sent to the second server immediately after the first request finishes and relies on the cache invalidation having completed in the second server, that the invalidation operation may not have completed at the second server before the second request is processed. In such a case, the second request may use stale data from the cache, and return incorrect results in its response.
Use session affinity to cause multiple requests from the same user session to go to the same application server.
USERS AFFECTED: WebSphere Commerce users who do not use session affinity to cause multiple requests from the same user session to go to the same application server. PROBLEM ABSTRACT: Configure data cache to delay after sending invalidations to specified object caches. BUSINESS IMPACT: Stale data to be used during the processing of a request RECOMMENDATION:
A new data cache configuration causes the application server request processing to wait for a specified number of milliseconds after issuing cache invalidations to any of specified object caches. For example, to configure a delay of 100 milliseconds after sending invalidations to the WCSessionDistributedMapCache object cache, add the following line to the CrossTransactionCache tag. (The CrossTransactionCache tag is found within the InstanceProperties tag in the wc-server.xml instance configuration file.) <WCSessionDistributedMapCache delayAfterInvalidationMilliseconds="100" /> Refer to the following URL for more information about the CrossTransactionCache tag: http://pic.dhe.ibm.com/infocenter/wchelp/v7r0m0/topic/com.ibm.co mmerce.admin.doc/concepts/cdcaddcomdatcacheconfig.htm ------------------------------------------------------------- The latest available maintenance information can be obtained from the Recommended Fixes for WebSphere Commerce technote: http://www.ibm.com/support/docview.wss?rs=3046&uid=swg21261296
