multiple sessions using transactions

Hi, we are using Java version of IControl API. We are using one and the same test user for multiple, parallel requests. Here is snippet of code that is behaving very inconsistently:   SystemSes...

Hi stojoman, you should set a Session Identifier to each request header to prevents multiple concurrent requests.

Please see https://devcentral.f5.com/articles/v11-icontrol-sessions

Here is sample

 SystemSessionBindingStub sessionStub = interfaces.getSystemSession();

 //get session identifier
 String session_identifier = String.valueOf(interfaces.getSystemSession().get_session_identifier());

 //set session identifier to each stabs 
 sessionStub.setHeader("urn:iControl", "session", session_identifier);
 interfaces.getGlobalLBWideIP().setHeader("urn:iControl", "session", session_identifier);
 interfaces.getGlobalLBPool().setHeader("urn:iControl", "session", session_identifier);
 ...

 // start transaction
 sessionStub.start_transaction();

 // do something
 ...

 // submit transaction  
 sessionStub.submit_transaction();

In addition, 

set_active_partition()
is not support Session, you need to use 
sessionStub.set_active_folder()
.

Hi uchi, thank you for your proposal. Adding session_id to each request solved some of my problems. Unfortunately running two transactions in parallel with the same user is still not working. Is this supported by IControl - Can a single user start more than one transaction at the same time? best regards Stoyan
