Hi,

We have a requirement like, we will get bulk data (2 GB) data file with different languages(Russian, chinese, Japanese, German) etc. and we need to load these data into our databse also we have to translate the same.

We are using Oracle 11g.

We had used Oracle httpuritype - And the below mentioned procedure PROCEDURE TEST.PRC_TRANS_GERMAN will call the function - trans_jef

Input parameter for PRC_TRANS_GERMAN - > To_language and from Language. and this procedure will store the translated word in the seperate table.
Input parameter for the function trans_jef - > Word to be translated , from languae, to_language. And this function will return the translated word.

The issue I am facing is when I am passing the table of around 10000 records, around 4000 rows are not getting translated. So when i try to capture the error in exception- the error is


ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1819
ORA-29270: too many open HTTP requests

When I try to re execute the missed words, they were translated. But they are not getting translated in one go because of the too many http open request.

So could you please let me know how to resolve this ORA-29270 errror.

Michel, If you could see the trans_jef function- i had just called the httpuritype. And since I am new to using http in oracle could you please advise me how to end the request and retry the request in trans_jef function. Thanks
