Refrshing cache?

[Former Member]

Hi Friends,

1. What will happen when we refresh the cache.?

2.why refreshing of cache in sxi_chache will resolve many errors in adapter engine etc etc, like the one issue resolved in the below forum?

3.In what all the specific situations we refresh cache in IR, ID and SXI_CAHCE?

Thanks,

Suresh.

Hi,

Cache is nothing but a buffer kinda where all the recently accessed data r stored.

so sometimes even after making changes u access the page the old data/page is displayed...

so Web AS cache works as a normal refresh deleting all the recently accessed data/pages...

it clears or frees ur memory so tht no irrelevant data is obtained...

for further details, refer to google search... " Web AS Cache Refresh in SAP-Xi"

refer to the following guide on XI caches:

Hi

In Simple watever object changes made in the SLD IR ID has to be available to the IS for runtime with the latest objects.

Implictly whenever u activate any objects it will get cache updated .

Same process can be explicitly using SXI_CACHE which does above functionality

Hi

There are 3 caches, so you have to know the purpose of each cache refresh.

1) SLD Cache - Used to cache the objects you created in SLD to runtime.You can check if SLD cache is updated or not in Integration repostory or Integration Directory.

2) CPA cache - Used to cache , adapter or communication channels as well as changes to adapter fraemwrok to runtime.You can check the status of this cache in http://<host><port>/CPACache

3) Repository cache - Used to cache Development obejcts from IR and ID e.g Message Type , Interface, Receiver determination etc .You can track this in SAP Transaction code SXI_CACHE.

Hope this help you.

Hi,

Cache maintain all the runtime objects.

If you r doing any changes to IR,ID objects, the changes may not reflected sometimes.

then we need cache refresh, which will update with recent verstion/status of the objects

Hi Suresh,

SXI_CACHE is used to refresh all the contents or messages stored in the queue
