Error while creating concurrent workflow instances with dynamic participant

Question

Hi All,
I have a workflow which has 3 interactive activites. The second interactive activity has requires approval of atleast 3 users to proceed. The participants are also not known in advance and are created dynamically by creating the directory session. The workflow is instantiated using an external trigger. The approval for interactive activities is also provided by an external trigger (API call).
Now, there is a scenario where i have 1000 requests coming in to ALBPM and workflow instance should be created for each of them. But only one instance is created and for the rest i get the following exception. This also happens with just 2 requests. I also tried calling the API in a synchronized way but didnt help.
Is anybody aware why is this error encountered anf how it can be resolved?

Hi Dan,
Thanks for replying and giving attention. I have the following scenario :-
1. I am getting a list of identifiers(some number) from a third party application along with the users/participants who are liable to approve the workflow instance.
2. I create a workflow instance using this identifier through PAPI using process service session and also create the user/participant through PAPI by using the following code. Please note that i dont create participant in ALBPM instead i do it programatically in java using the PAPI :-
DirectorySession directorysession = null;
if (userVO != null && userVO.getUserId() != null && !userVO.getUserId().trim().equals(""))
+{+
+     directorysession = this.createFDISession();+
+     List<RoleAssignment> roleAssignmentList = new ArrayList<RoleAssignment>();+
+     try {+
DirOrganizationalRole[] dirOrganizationalRoleArray = DirOrganizationalRole.fetchAll(directorysession);
for(int i=0; dirOrganizationalRoleArray!=null && i<dirOrganizationalRoleArray.length; i+) {+
+DirOrganizationalRole role = dirOrganizationalRoleArray;+
+}+
int permissions = -1;
permissions
+= 0 |+
DirHumanParticipant.getPermissionValue("X") |
DirHumanParticipant.getPermissionValue("R") |
DirHumanParticipant.getPermissionValue("S") |
DirHumanParticipant.getPermissionValue("A") |
DirHumanParticipant.getPermissionValue("D") |
DirHumanParticipant.getPermissionValue("E") |
+0;+
+String[] whichRoles = new String[]{+
+"Approver",+
+"Requestor",+
+};+
+DirHumanParticipant.RoleAssignment[] roleAssignments = new DirHumanParticipant.RoleAssignment[whichRoles.length];+
for(int i=0; i<whichRoles.length; i+) {+
+roleAssignments[i] = new DirHumanParticipant.RoleAssignment(whichRoles[i], permissions, DirOrganizationalRole.fetch(directorysession, whichRoles[i]).getIn());+
+}+
+     String organizationUnit = configuration.getProperty("ORGANIZATION_UNIT");//fuegoFileProperties.getProperty(BVIDConstants.FUEGO_CONNECTIVITY_KEY_ORGANIZATION_UNIT);+
+     String newUserPwd = configuration.getProperty("FUEGO_FDI_NEW_USER_PASSWORD");//fuegoFileProperties.getProperty(BVIDConstants.FUEGO_CONNECTIVITY_KEY_FDI_PWD);+
+     DirOrganizationalUnit orgUnit = DirOrganizationalUnit.fetch(directorysession,organizationUnit);+
+     DirHumanParticipant user = DirHumanParticipant.create(directorysession, userVO.getUserId(), userVO.getFirstName(), userVO.getLastName(),+
+                              userVO.getFirstName(), userVO.getEmail(), userVO.getPhone(), "",+
+                              newUserPwd, orgUnit,roleAssignments, true);+
+     user.update();+
+     }+
+     finally+
+     {+
+               log.info("diconnecting the directory session created for creating participant");+
+               directorysession.disconnect();+
+     }+
+}+
3. The workflow instance then waits at interactive activity to get the next trigger with the same identifier to move the workflow ahead.
4. Now the case is that i can get 1000 such identifiers at a time in a file which i ll read for which i need to create 1000 workflow instances parallely. During this process i get the following exception : -
java.lang.IllegalStateException: Cannot set the directory Connector Service while connector service is started

Please let me know if you need any more information. awaiting your help
