Cache Refresh Issue with PI load balanced HA setup.

[Former Member]

Dear Experts,

We have installed a HA Load Balanced PI Server with the below specifications. Its a four node cluster. Two nodes for Application Cluster and another two nodes for Database Cluster.

Node1

Physical Hostname : axsappci

Virtual Hostname : axsapp00

Instances : CI,SCS and ASCS.

Node2

Physical Hostname : axsappdi

Virtual Hostname : axsapp00

Instances : Dialog instance installed with physical hostname axsappdi

Node3

Physical Hostname : axsappd1

Virtual Hostname : axsappdb

Instances : DB Instance.

Node4

Physical Hostname : axsappd2

Virtual Hostname : axsappdb

Instances : Standby DB Instance (passive).

Web Dispatcher Hostname : h2h

Application Switchover : CI,SCS and ASCS to switchover to Node2 and dialog instance Node2 forcing to go down

Database Switchover : DB Instance switchover to Node2 if Node1 fails.

We have changed all the parameters according to note 951910 -> NW2004s High Availability Usage Type PI

I am facing an issue with the cache Notifications in the Integration Repository and Directory. The cache notifications are not happening properly particularly with the ABAP Cache.

I get the below error in my ID when i try to do the manual cache notification.

Unable to notify integration runtime (ABAP) of data changes

Unable to establish http connection "http://h2h:8002/sap/xi/cache?sap-

client=001"

Kindly assist.

Thanks and Regards

Hi,

See if the SLDCHECK is running successfully and also there is no error in SXI_CACHE.

Hi Swarup,

Thanks for the reply.

My SLDCHECK and SXI_CACHE works fine. There are no errors.

The problem is i am not able to reach the PI server cache from my Web dispatcher.

There is also one more issue. When i start my dialog instance the SLD registration does not happen properly and i get the adapter engine error when i open ID->cache notifications which says adapter engine is not registered for dialog instance properly.

I have implemented note 764176 and 1031321 multiple times. But stil the issue is the same.

Kindly assist.

Regards

Raghu.
