Call Adapter Error - 401 Unauthorized

[Former Member]

Hi,

We are using Multi Mapping where it splits 1 message into n messages. The n messages split by this scenario in trun calls another scenario configured in the same PI server using SOAP Adapter.

The called scenario is SOAP --> Siebel using iWay Adapter.

When the number of messages split are huge in order of thousands, the server is going for a toss and the called scenaio is failing at Call Adapter Step in IE with HTTP Error 401 Unauthorized. Few of the messages manage to pass successfully.

Anticipating your valuable inputs.

Thanks.

Hi Sudharshan,

There can be different reasons for getting HTTP 401: Unauthorized error. As you said, few of the messages are being passed to the called application, I would request you to check the scalability of the Seibel Server.

Also if you are using a connections from a connection pool, then it may be that the pool itself is getting exhausted, though mostly we get Socket exception/Connection Exception/IO Errors in these cases.

The other reasons can be that the user you are using to connect Seibel dont have enough permissions. But it is ruled out as you said some messages have been processed.

If the Seibel server is SSL enabled, and your PI doesn't have any certificate configured, then also you may get such errors.

Hi Sudharshan,

Is your XI box and Seibel in the same zone?/LAN zone?. If not then you may try out one more thing. Try to run telnet to the Seibel system IP (Webservice IP) and communication port (Web Service port) from your XI system and see what it says? If they are on the same zone , then it is a definite case of permission issue, else you need to open communication port for bi-directional communication from XI to Seibel or vice-versa.

thanks and regards,

Hi Sudharshan,

In my point of view about this error "HTTP 401 Unauthorized".

"Unauthorized" Means Authorization error.

There is lot of cases are failed to this message.

1) End User may be entered wrong user name & Pwd for the sending the files.

2) Check your particular server is properly working or not.

Hi

Check this document (page 8-9)

http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/c059d583-a551-2c10-e095-eb5d95e03747&override...

it says

Check these parameters in NWA / VA:

ume.r3.connection.master.poolmaxsize

ume.r3.connection.master.poolmaxwait

Default Max. Connections: 20

Default Max. Wait Time: 10.000 ms

Increase parameters until problem disappears: for example,

Max. Connections=50, Max. Wait Time=60000
