Dear Experts,

Wei have installed a HA Load Balanced PI Production 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

Check all abap ports are pointing to 8000 based on your instance number and java to 50000 in exchange profile

Hi Srikanth,

Thanks for the reply.

I have configured my web disptacher to use default HTTP and HTTPS ports i.e 80 and 443. According to note 951910 i have changed parameters in exchange profile to use these ports.

Regards

Raghu.
