Hi Kiran,

the XI cache gets usually refreshed by itself. So in most cases you don't need to worry about it. The cache is used to let the system perform smoother. Imagine it had to read all the interface information each time an idoc is sent.

Sometimes the cache is not properly updated. You can see in SXI_CACHE all your Interfaces, communication channels, Idocs etc. If for some reason you have a difference between your Integration Builder and your Cache (after you made sure you activated your changes in the Integration Builder) you can try a cache refresh to get your systems up to date.

Of course there are few exceptions but generally you don't have to worry about it.

If your questions is not answered please let me know.

Hi,

In some cases when you change an object that was created before and activate the changes are not reflected. XI uses the older version of the object during execution.The newer version of the object is not reflected. Then you have to do a cache refresh to reflect the modified changes.

there can be multiple situations when u might have to enforce a cache refresh.

Suppose you did a recent change to a mapping and activated the same. but when your scenario is run u seem to see the old mapping being called etc. in tht case, a manual cache refresh is done.

same as in case of ID objects, your communication channel, recv. det. etc

Hi Kiran,

Cache refreshing means getting the newly created component in the cache. Usually cache get refreshed automatically by SAP system and user do no thave to refresh it but in some cases the newly created component does not get dispalyed in cache. In that case this cache should be refreshed and it will pull out the new component in it.

Hi Kiran,

Refreshing the cache means, back end connections are made during the next request and the cache is validated for any new or any deleted items. Before contacting the back ends, expired items are removed from the cache.

Please let me know if you have any further queries.

Thanks and Regards,

The cache refreshing is a task in XI to get the latest copy of the objects created or changed into the cache of the XI server. usually it is done automatically.

sxi_cache - this tcode is used to manually refresh the cache and also to view the status of the objeccts in the cache. (/people/sravya.talanki2/blog/2005/12/02/sxicache--ripped-off)
