Hello!

If my tamino database is closed and then in IE6 I execute the following command:

http://localhost/tamino/mydb/col?_xql=count(/doc)

then I get the following message text:
–
<?xml version="1.0" ?>
- <ino:response xmlns:ino=“http://namespaces.softwareag.com/tamino/response2”>
- <ino:message ino:returnvalue=“8201”>
<ino:messagetext ino:code=“INOXHE8201”>Can’t connect to server on host localhost at port 3273, TCP error code 10061.</ino:messagetext>
</ino:message>
</ino:response>
–

So, error code is 8201.

However using TaminoClient I get:
error code 8400.

How can I get the same error code like in IE?

Thanks in advance!

best regards,

Hi Dariusz,

The TaminoClient throws error 8400 whenever a databases is not accessible, which could be when the database is offline and/or the web server is offline. Whenever there is a communication error, the response will always be 8400 as far as the API is concerned.

The API checks the response from Tamino and if it is 8202 it throws a TaminoError with error code 8400 - so this “feature” is built into the API itself. IMHO I think it is correct that a common error number should be given in the event of a communication error. The field errorText of TaminoError then provides a specific error.

http://localhost/tamino/my1db/col?_xql=doc
ino:returnvalue=“8202”>
Tamino database unknown: my1db

http://localhost/tamino/mydb/c1ol?_xql=doc
ino:returnvalue=“8811”
Collection name not found
Collection name = c1ol

Unfortunately, in these above queries TaminoError always return 8400. Why?

Hi Dariusz,

The API does not change response 8811 into 8400; in fact the TaminoError exception is not raised at all. The only time error 8400 occurs is if there is really is a connection problem. I tried this with Tamino v3121.
