Automated cache notifications in IR

Hi Guru's

we are on SAP PI 7.11 EHP1 SP 10.

for DB upgrade, we have copied existing PI system into new box. Everything is working fine except automatic cache notifications on IR.

For any changes on IR objects, we have to manually perform the cache notification. There are no errors on the basis side and compared the new system with old system and couldnt find any difference.

I have searched many blogs, but couldnt find exact solution for this.

Any help in this will be appreciated. Thanks.

Thanks,

Giridhar
