Asset Cache Not Updated on Other Cluster Members after Asset is updated on primary cluster member

With WebCenter Sites or later , after updating an asset on a primary cluster member , Asset Cache on other cluster member takes a while to update

Below are the two  possible causes of this issues

1.Incorrect Mutilcast setting 

  • Ensure that for each cluster member, the cs-cache.xml and linked-cache.xml has the same multicastGroupAddress and multicastGroupPort.
  • Make sure that the timeToLive is set appropriately. If the timeToLive is set to 0, but the cluster members are on different machines, the multicast messages will not reach the other cluster members.
  • The following are the valid settings for timeToLive

0 – same host
1 – same subnet
32 – same site
64 – same region
128 – same continent
255 – unrestricted

2.Check if all WebCenter Sites cluster members have synchronized system times

Pre Upgrade Activities

  1. Make sure there are no open DB connections

  3. For JDK 1.6, copy the jaxb-impl-2.1.12.jar
  4. Update Classpath with MSXML.jar : Missing with our scripts
  5. Update start-up scripts with XX:MaxPermSize and -Dcs.useJavaURLDecoder to false and other JVM settings
  6. Update LD_LIBRARY_PATH with CS-INSTALL\bin directory
  7. Ensure that all external data feeds and events are disabled
  8. Disable Revision Tracking for the assettypes
  9. Add the path to WebCenter Sites’ modified version of the Microsoft XML Parser (MSXML.jar in the WEB-INF/lib directory).

  1. Copy Property Files

  6. Create the start menus for PageAttribute, PageDefinition, and PageFilter so these asset types can be used.
  7. Re-Register the basic asset types
  8. Re apply any customizations on basic assets
  9. Enable Revision Tracking
  10. To enable publishing of site plan assets to the delivery system, initialize the RealTime destination. Initialization
  11. Create the SitePlan asset type on delivery
