CACHE NOTIFICATIONS

Hi,
Whenever i activate the change list, i could see some errors in the cache notifications(Environment->Cache Notifications).
The errors are
1) Unable to contact Adapter Engine "af.mtx.bw" that is affected by the data changes
2)http connection to "http://bw:8200/CPACache/invalidate" returns the status code "401" in response
How do i resolve this?
I have plain J2SE Adapter Engine installed on my m/c. In my Adapter Configuration, i have only one entry under the Adapter Engine Drop down box(instance is Integration Server). Is it correct or should i get my decentral adapter engine in that drop down box?
My configuration changes are not getting reflected in the SXI_CACHE tcode.For ex. i have a sender agreement in my ID. But its not present under the SXI_CACHE TCODE.similarly communication channel is missing in XI Runtime Cache.
Thanks in advance

Amith

Hi,
MY SLD is connected to the AE. Bcoz i could see my AE Entries in the sld and my SLDACCESSOR is working properly in AE.
When i try to refresh the cache in Integration Directory for the cache instance CENTRAL INTEGRATION SERVER, i am getting a message that
"http connection to "http://bwxi:8200/CPACache/invalidate" returns the status code "401" in response"
Sometimes i am getting a message saying that SAP_XIADAPTER FRAMEWORK is not found in SLD.
what do i need to do?

Cache Notifications unable to determine name of Central Adapter Engine

Hi All,
When I tried Tools -> Cache Notifications in the integration directory, im getting
Unable to determine the name of the central Adapter Engine from the System Landscape Directory at this time.
Notifications to the central Adapter Engine are therefore listed using the technical name of the Adapter Engine.
This is usually structured as follows: af.<SAP System ID>.<Name of application server>
Once i click the OK on the pop up dialog which has this message, it has given the Notifications and Problems Tab.
In the Problems Tab, its has given an error message
'Unable to find an associated SLD element (source element: SAP_XIIntegrationServer"
Any suggestion of what to look for to modify ??
Thanks

Integration Builder (Design) - Cache notification

Friends,
When we save the objects in Design (Integration Builder), the objects goes to status "Notification Not Yet Started" or "Red" in the cache notification screen. The developer has to manually execute the repeat cache notification to make it successful. Is there any settings or configuration missing? can you please guide me?
Thanks,
Peter

Hi,
Since your cache in getting update automatically, therefore you should check the RFC in SM59 as mentioned in this document.
First check this one...

Integration Directory - Cache Notifications Error!!

Hi ,
When i try to select "Cache Notifications" in directory i am facing this error below.
Unable to determine the name of the central Adapter Engine from the System Landscape Directory at this time. Notifications to the central Adapter Engine are therefore listed using the technical name of the Adapter Engine. This is usually structured as follows: af.<SAP System ID>.<Name of application server>
I can see in SLD -> technical system -> exchange infrastructure, the entry for Integration Directory is missing. I ve applied note 764176 , but it is not helping. Similarly the entry for RWB is also missing here.
ve checked in SLD -> Admin -> Content Manitenance and the assocations are missing for IR & RWB. I beleive these errors are closely related. ve chked exchange profile XIDIRUSER & XIRWBUSER pwds , chked the roles , they are the same as our DEV / QA envionments.
Can anyone pls point what am i missing here
Thanks
Saravana

Hi Saravana,
About the roles for XIRWBUSER...you can check the same in the ABAP stack...go to transaction SU01 and check the Roles attached...it should have the following entries...
SAP_SLD_CONFIGURATOR
SAP_XI_RWB_SERV_USER
SAP_XI_RWB_SERV_USER_MAIN
These should be sufficient as it is working for us...also...the roles gets passed along from the abap stack to the J2ee stack....
Now to your original issue...we had to change our sld in our system to a new box and had to re-configure....we got the same error that you were getting...
we corrected it by doing the following...
Corrected the entries in the Visual Admin under SLD data supplier service... for the HTTP tab as well as the CIM tab.
Did the SLDCHECK(TCODE on abap stack) and made sure everything was ok....
Did a CPACache refresh full...and of course a restart....
that solved the issue for us...
Thanks,
Renjith

Cache Notifications Error in Integration Directory

Hello,
I'm having an interesting problem at my client's PI 7.0 system. When I update my changelist, I can see problems in Integration Directory - cache notifications. Integration Builder works fine. When I retry the cache refresh manually, I turns to green.
But, Communication Channels with adapter type XI are not created even when I activate my changelist and manually fix the cache refresh if there are errors. All other adapters can be seen in Component Monitoring - Adapter Engine - CC Monitoring, but XI type adapters are not there.
How can we resolve this problem?
Thank you,
Gökhan

Hi,
Check all steps in this doc (Especially from Page 20 to 24): [https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/c0332b2a-eb97-2910-b6ba-dbe52a01be34|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/c0332b2a-eb97-2910-b6ba-dbe52a01be34]

Integration Directory - Cache Notifications

I just installed QA box. I am trying to move my Integration Directory objects. When I do cache notifications in ID I get an error in the cache notifications Integration Server (ABAP Cache).
Any help is appreciated.

Hi Michael,
What type of error are you getting ?
Anyway if you did not go thru this document, then please have a look into this-
https://websmp101.sap-ag.de/~sapidb/011000358700003163902004E/HowTo_handle_XI_30_Caches.pdf

Integration Directory, Cache Notifications with error

Guys,
In Integration Directory, I create one Comunication Channel, but, when i actived one, it dosnt appears in RWB Comunication Channel Monitoring.
In Integration Directory -> Environment -> Cache Notifications, show the following error:
Integration Server (Central Adapter Engine) | Directory Change List | pisuper | Standard Change List
With "Standard Change List" as: Not Yet Started
Details: Never change Status.
Can anybody help me?

Also check in SLD technical system for Exchange Infraustructure.
Check weather Adapter enginer is registered or not.
Your XI domain should contains 6 entries
1.Adapter engine
2.Domain
3.Integration Directory
4.Integration Repository
5.Integration Server
6.RWB

Sending cache notifications to the backend ABAP

Hi,
1. How the cache notifications are sent to the backend ABAP?
2. What is the role of INTEGRATION_DIRECTORY_HMI ( /dir/CacheRefresh )?
3. If I need to require cache notifications to be sent from PI (ABAP 7.1) to ECC (ABAP 7.0), do i need to have INTEGRATION_DIRECTORY_HMI in ECC?
Thanks and regards,
Sreehari

Hi Abhishek,
Just want to be clear about one thing. If INTEGRATION_DIRECTORY_HMI stores the cache updates, and I need to send these updates to ECC ( which is on a seperate AS ), ideally I should be having the RFC destination in ECC as well.
My understanding was if the RFC destination exist in PI, it will send cache notifications to the ABAP of PI. If we need to send cache notifications to some other ABAP system in the landscape, we need to have the RFC destination there as well. Please correct me if I am wrong.
Many Thanks and regards,
Sreehari

ID-Cache Notification

Hi All,
When I select Cache Notifications from Environment tab in ID, I am getting errors. Cache updated status is red, also the date/time is 00.00.00 00:00. But the perform Notification status is green and the date/time is set properly.
Advise me on this.
Thanks & Regards,
Jai Shankar.

Hi,
Please can you do delta refresh from SXI_CACHE and see if it's running successfully.
Also, pleaae check if RFC destination INTEGRATION_DIRECTORY_HMI is working fine.
ALso, look at doc:
https://websmp101.sap-ag.de/~sapidb/011000358700003163902004E/HowTo_handle_XI_30_Caches.pdf

Int Dir Environment Cache Notifications - Error

Every one,
Int Dir > Environment > Cache Notifications, gives the follwoing Dialog,
Unable to determine the name of the central Adapter Engine from the System Landscape Directory at this time. Notifications to the central Adapter Engine are therefore listed using the technical name of the Adapter Engine. This is usually structured as follows: af.<SAP System ID>.<Name of application server>
sxi_cache on the abap stack works fine.
My guess is that,
I did not create any SLD entry for the central AE. That could be the problem.
We have all the components on a single server and only one AE. There are no remote AEs.
-Naveen.

Naveen,
This is because of incosistence of SLD entries- refer SAP Note - 764176 and do accordingly.

Azure Cache Notifications

I'm trying to work with Azure Caching Notifications. Seems that the Callback is never invoked. CreateCache() and AddItemCache() are called onClick. I have correctly enabled Notifications in the Azure Management Portal. What am I missing ?
private DataCache cache = new DataCache();
public void CreateCache()
DataCacheFactory cacheFactory = new DataCacheFactory();
cache = cacheFactory.GetCache("never");
cache.CreateRegion(App.IDProject.ToString());
DataCacheOperations allCacheOperations = DataCacheOperations.AddItem |
DataCacheOperations.ReplaceItem |
DataCacheOperations.RemoveItem;
DataCacheNotificationDescriptor ndCacheLvlAllOps = cache.AddRegionLevelCallback(App.IDProject.ToString(), allCacheOperations, new DataCacheNotificationCallback(myCacheLvlDelegate));
public void myCacheLvlDelegate(string myCacheName, string myRegion, string myKey, DataCacheItemVersion itemVersion, DataCacheOperations OperationId, DataCacheNotificationDescriptor nd)
//display some of the delegate parameters
Logger.Info("A cache-level notification was triggered!");
Logger.Info(" Cache: " + myCacheName);
Logger.Info(" Region: " + myRegion);
Logger.Info(" Key: " + myKey);
Logger.Info(" Operation: " + OperationId.ToString());
Logger.Info("");
// to do
MessageBox.Show("You should update");
public void AddItemCache(Tuple<int, int,string> tuple)
cache.Add(tuple.Item2.ToString(), tuple.Item3, App.IDProject.ToString());

Hi,
Would you be able to tell us if you are trying to use Cache, Region or Item level callback?
You could refer the link for details on AddCacheLevelCallback method:

Hi,
In the Integration directory>environment>cache notifications the Integration Server(Java Cache) and Integration Server(Central adapter engine) have a cache updated status with error (red light)
Kindly suggest what could be the problem

Try a check via SXI_CACHE and try a complete cache refresh.
Also try running the report SAI_CACHE_REFRESH

Error in Cache Notification .."CPASchemaException"

Hello gurus,
Our XI tech consultant is facing an error in Cache Notifications. He thinks its a installation/configuration problem from the basis side. Now i am new to XI, don't really know where to start.
Here's the background :
1. He is configuring a File 2 File scenario as a demo in XI.
2. Believe he has configured sender and receiver communication channels.
3. File Adapter - Input/output File Type XML/binary
He is getting error in Cache Notifications : Sender Agreement

Any ideas folks ??

Azure Dedicated Role Cache does not fire notification to client when call DataCache.Clear method

Hi,
I'm using Azure Dedicated Role cache and Enabled the local cache and notification.
<localCache isEnabled="true" sync="NotificationBased" objectCount="20000" ttlValue="3600" />
<clientNotification pollInterval="1" maxQueueLength="10000" />
but when I call DataCache.Clear method in one client, the notification does not send to all clients, the client's local cached content still been used.
is this a bug of Azure SDK 2.5?

I assume that you have correctly configured and enabled Cache notifications, instead of using the DataCache's clear method - have you tried clearing all regions in your cache because I am not sure if DataCache.Clear triggers the cache notification or not.
so your code should look something like this
foreach (string regionName in cache.GetSystemRegions())
cache.ClearRegion(regionName)
You can refer the link which explains about Triggering Cache Notifications https://msdn.microsoft.com/en-us/library/ee808091(v=azure.10).aspx
