Cache problems in PI REST adapter

[harish_babu5]

Hi guys,

I am facing cache issues in PO single stack REST adapter.

Same data is fetched again and again when interface is run end to end. If I make a dummy change to the communication channel then I will get fresh data.

For example I am posting or using get method at sender REST adapter. I have a receiver system.

When I use a GET method to get a particular plant details, I get it. Now when I change the plant number in the GET method also I get the same pplant details. If I make a change in my sender REST communication channel, any dummy change, then new data is fetched.

Suppose I query for plant 1100, I will get that from ECC. Now I make dummy change in REST sender cc, and querry for plant 1200, i get detauils for plant 1200.

However without making any dummy changes to sender REST CC, I am not able to fetch new date

Hi Harish,

Kindly check if your PI SP version is affected by this note  2258139 - REST sender channel is caching values from HTTP requests

Hi Inaki

Exactly, that's my problem. My SP version is affected by this.

I guess I need to do a patch upgrade for this.

Hi Inaki

The issue was resolved by applying the patch. The PO system is not getting cached and new requests are taking new values.

Thanks
