Cache Update Error

[Former Member]

Hi all,

I'm very new to SAP PI,

When I try to refresh the cache using SXI_CACHE , I'm getting this following error,

"Unable to Refresh Cache Contents"

"Error during last attemopt tp refresh cache"

When double click on the error I'm getting

"ERROR ID: UPDATE"

<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">

Any help regarding this issue is appreciated,

Hi,

Possibly it is an issue with RFC destination INTEGRATION_DIRECTORY_HMI.

Please also look at the links

http://wiki.sdn.sap.com/wiki/display/XI/SXI_CACHE+Common+Errors

http://scn.sap.com/message/11158447

This should help you resolve the error.

Thnks for the reply Ambrish,

I've already checked RFC destination INTEGRATION_DIRECTORY_HMI by looking at other threads.

here PATH PREFIX: "/sap/xi/engine/?type=entry" 

(is this correct?, it was already present when I checked it)

Also when I clicked on Connection Test I got the following response which is alright i guess.

Hi Arun,

Path should be /dir/CacheRefresh.

Target host/port value would come from Basis.

Arun,

I think you missed my response above.

Hi Ambrish,

I replaced the PATH PREFIX :"/sap/xi/engine/?type=entry" with "dir/CacheRefresh"

still same error exists even after restarting the server.

Hi Arun,

Does the connection test work ? You can also try recreating the connection.

Check if cache notifications are working in Integration directory. If not, try to repeat notifications and clear the errors.

Another good link is below:

http://scn.sap.com/docs/DOC-16019

Hope it helps

Hi Ambrish,

Test Connection is working fine,

In Integration Builder when I clicked on "Environment"-->"Cache Status Overview", got the following pop up (Please click on image for better view)

also when i clciked on Close button, i got this

here you can see that the status is in grey color which indicates "Not yet Started", I tried "Repeat Cache for that instance", "Refreshing Cache" still it is same as above.

Hi AB,

You need to involve the basis team now. There are inconsistencies in the SLD. I had a similar issue in my production environment where I needed to register the components again in SLD.

Also different URLs should be changed to FQDNs.

Take a look at http://scn.sap.com/message/740705

Some of the OSS notes which may help are 720717, 721548,764176, 804124.

Hope it helps!

Hi Arun,

Check your path prefix    "dir/CacheRefresh"

'H'  type connection

it should be

/dir/CacheRefresh

Thanks & Regards,

INTEGRATION_DIRECTORY_HMI is used for cache updates. See this -

http://help.sap.com/saphelp_nwpi71/helpdata/en/8f/770f41218ff023e10000000a155106/frameset.htm

Further, can you execute transaction SLDCHECK. This has more information and should help you to check it in details for subsequent steps.
