Call ODI Scenario from PLSQL

Call ODI Scenario from PLSQL:

I was discussing with one of my friend on this without calling a batch file from PLSQL. Since webservice is a best method to invoke odi scenario outside odistudio, lets use the soap envelop to kick the scenario from plsql program. Here is the code.

DECLARE

req_envelop VARCHAR2(4000) := ‘<soapenv:Envelope xmlns:soapenv=”http://schemas.xmlsoap.org/soap/envelope/” xmlns:odi=”xmlns.oracle.com/odi/OdiInvoke/“>

<soapenv:Header/>

<soapenv:Body>

<odi:OdiStartScenRequest>

<OdiUser>SUPERVISOR</OdiUser>

<OdiPassword>SUNOPSIS</OdiPassword>

<WorkRepository>WORKREP91</WorkRepository>

</Credentials>

<ScenarioName>PKG_SCOTT</ScenarioName>

<Context>GLOBAL</Context>

<!–Optional:–>

<Synchronous>false</Synchronous>

<!–Optional:–>

</Request>

</odi:OdiStartScenRequest>

</soapenv:Body>

</soapenv:Envelope>’;

req utl_http.req;

res utl_http.resp;

res_envelop VARCHAR2(32767);

BEGIN

req := utl_http.begin_request(‘http://localhost:20910/oraclediagent/OdiInvoke?wsdl‘,‘POST’,’HTTP/1.1′);

utl_http.set_header(req, ‘Content-Type’, ‘text/xml’);

utl_http.set_header(req, ‘Content-Length’, length(req_envelop));

utl_http.set_header(req, ‘SOAPAction’, ‘invokeStartScen’);

utl_http.write_text(req, req_envelop);

res := utl_http.get_response(req);

utl_http.read_text(res, res_envelop);

utl_http.end_response(res);

dbms_output.put_line(res_envelop);

END;

Now execute above codes with proper parameters and you will find out the response as given below.

<?xml version=”1.0″ ?>

<S:Envelope xmlns:S=”http://schemas.xmlsoap.org/soap/envelope/“>

<S:Body>

<ns2:OdiStartScenResponse xmlns:ns2=”xmlns.oracle.com/odi/OdiInvoke/“>

</ns2:OdiStartScenResponse>

</S:Body>

</S:Envelope>

Now Its Done. Check your operator for the session 2518091.

See You in the next post.

Hi Bhabani,

Very nice simple solution. I tried this. I am using ODI 11.1.1.5. Problem is: ODI webservice accepts only one parameter. If I pass more than one it takes in consideration only last one. Is there some workaround for that?

Best regards,
Ed

Great ODI SOAP example. Do you know how to call a Load Plan using a SOAP call? I’ve tried the same syntax but no luck.
Thanks in advance.

Hi Bhabani,
Greetings!!!!

I am a newbie when it comes to execute an ODI scenario through PL/SQL.

I reffered to your piece of code and passed below mentioned values.

OdiUser
OdiPassword
WorkRepository
ScenarioName
ScenarioVersion

When I executed the Pl/Sql block sql developer prompting me for Enter Binds. Do I need to change any other parameter value and values passed to Bind variables?

I am facing error after execution. Missing IN or OUT parameter at index:: 9.

It will be really grateful if you can help me with issue.
Looking forward to your reply.

Thanks In advance.

Hi,

I want to use Oracle Wallet for the SOAP call, so i used the following syntax

DECLARE
req UTL_HTTP.req;
BEGIN
UTL_HTTP.SET_WALLET(path => ‘file:/eeeee/oracle/wallets ‘);
req :=
UTL_HTTP.begin_request (v_odi_invoke_url, ‘POST’, ‘HTTP/1.1’);
UTL_HTTP.SET_AUTHENTICATION_FROM_WALLET(req, ‘odi-wallet-acesss’);

END;

AND MY req_envelop had the following values without providing user name and password of ODI,

req_envelop :=’

QUESTION: Using the above code, when we tried to execute the pl/sql package , the soap call returns with an error , reading that the credentials are not mentioned. surely there is something wrong with the syntax. could you please suggest?
