ABAP engine components : BPE, IE.

Now pls tell me the where does SXI_Cache reside and its purpose in simple defination.

Hi,

the below blog will explain your doubts

SXI_CACHE - Ripped Off

This transaction is useful for troubleshooting and support within SAP Exchange Infrastructure. You can call to analyze the cache

CPA Cache

Cache monitoring monitors cache objects. Selection criteria are available for each cache object; you can use these selection criteria to search for current objects in the runtime cache

CPA cache means it will contains the cache copy of all objects created during configuration time (ID)

To monitor the CPA cache

Purpose:

SXI_CACHE: A memory area where the information about the design and configuration objects of the J2EE stack is stored in temporary ABAP data dictionary tables. The integration engine uses it at the run time for accessing the appropriate design and configuration objects of J2EE stack.

Check weblog for more understanding:

CPA cache - is your Collaboration profile agreement cache, ie to mean it will contains the cache copy of all objects created during configuration time (ID)

Runtime cache - it will contain cache copies of all the objects in XI (IR/ID)

Hi All,

Sxi_Cache

Objects (IR(Java Stack) and ID (Java Stack))are activated they are put in Sxi_Cache(Abap Stack) as they are required

by IE (Abap Stack) for processing.

As suggested by you CPA cache

contains cache copy of all objects created during configuration time (ID)

Since ID objects are already sent to SXI_Cache then how it is used for CPA Cache.

I am clear for SXI_Cache but not for CPA Cache.

Pls advice..

Hi Rick,

CPA cache used in adapter framework during runtime,accessed at http://server:port/CPACache where port refers to the J2ee port.

Whereas SXI_CACHE is used for runtime active versions of Integration engine.i.e it validates the active connection between IR, ID and SLD during runtime. Also it is used to check the runtime active version of integration process (BPM).
