RE: Time limitation for Systools.Httppostclobverbose -- RPG400-L

Hi Martijn,

In the IBM documentation, they talk about milliseconds :
https://www.ibm.com/docs/en/i/7.3?topic=systools-http-function-overview
Would they have made a typo ?

Hello Jean-Marc

My educated guess would be that the values in the request header should be modified to reflect the behaviour you want the HTTP Post to have.

<header name="connectionTimeout" +
value="120000" /> +
<header name="readTimeout" +
value="120000" /> +

The values for the timeouts ("120000") stand for 120,000 seconds which is over 33 hours. If you decrease these values, the SQL query will stop with an error response at an earlier moment

Kind regards,
Martijn van Breden

Hi,

I have the following embedded SQL query :
EXEC SQL
SELECT VARCHAR(Responsemsg, 2048),
VARCHAR(Responsehttpheader, 512)
INTO:Responsemsg INDICATOR:Nullresponsemsg,
:Responsehttpheader INDICATOR :Nullresponsehttpheader
FROM TABLE( Systools.Httppostclobverbose(TRIM(:Url) ,
CAST (:Httpheader AS CLOB(1k)),
CAST(:Requestmsg AS CLOB(10k))));

With
httpHeader = '<httpHeader> +
<header name="connectionTimeout" +
value="120000" /> +
<header name="readTimeout" +
value="120000" /> +
<header name="Content-Type" +
value="*/*" /> +
<header name="Ocp-Apim-Subscription-Key" +
value="' + %trim(ApiKey) + '" /> +
<header name="X-Correlation-ID" +
value="' + %trim(CorrelationID) + '" /> +
</httpHeader>';

It has been running without problem for months but during one run, it "froze" until the processing was stopped 8 hours later.
The logs show that a response was sent but never received by the request.
Question: Is there a way to limit/control the execution time of a query?

Cordialement,
