    Hi Yue,


    What we typically do is that we ´create a the "mother study" with each site a subsidy. Each investigator and CRC can then only see his/her own site while the CRA or study director can see all the sites.

    First you build the main study  (item 1- 5) and when this is done you create the sites (item 6) and assign the users (item 7).

    Good luck

    Hi Yue,

    There's some good documentation about creating studies:  https://docs.openclinica.com/3.1/administer-study. As Krister points out, first you would create your study, then you would add sites to the study.

    Thank you Krister, > > We are experiencing the internet connection problem at the moment. First time I used OC community edition to set up a 2 sites study which requires the research nurses from  2 different hospitals at different county to login onto the study online remotely for the data entry. > > Now the nurses complain "The problem  appears to have escalated since we  initially asked for help , as currently we cannot access anything in open Clinica ,keeps saying "cannot access that web page." > > But the IT guys from both sites feedback " The comment that I have gotten back is it’s difficult to ascertain what the issue might be given that there are no security or firewall restrictions in place with regards to accessing http://10.168.250.200/OpenClinica.  As your issue seems to pertain to saving data there may be some specific network configurations that need to be in place however as I am unfamiliar with the software this is only a guess.  In order to troubleshoot this aspect the network team may need to monitor your connection in real time so that can see where the ‘traffic’ is being directed to.". > > Still not sure whether due to the community  edition's limitation. > > Do you have experiences using OC community on multi sites at different locations requires network connection ? > > Many thanks, > > Yue

    Hi Yue,

    You should not have any problems accessing OpenClinica from different countries. Are you sure Tomcat is running? You have to include the server port in your start up string e.g.

    http://10.168,250.200:8080/OpenClinica/   You also have to make sure that the server .

    allows remote access in the fire wall,

    Hope this helps


    Regards

    Hi Yue.  

    A way to check the location of the problem is to try to access the Tomcat webserver by http://10.168.250.200:8080/  

    If you get the Tomcat welcome page, your network connections are probably fine and the issue could be with your OpenClinica installation, or OpenClinica is not started on the webserver.   To check this out use the Tomcat Manager (http://10.168.250.200:8080/manager) to see if Tomcat thinks OpenClinica is started, but first look at http://chandank.com/application-server/tomcat/tomcat-login-problem which shows you how to specify the access.

    If however you do not get the Tomcat welcome page, you have either a network problem or Tomcat is not running.   At this point you need your network support people.

    Another possible cause could be low network bandwidth if you are operating in remote locations - I've heard reports of not being able to use OpenClinica in some of the remote areas of South Africa where the only network access available is a 2.5G mobile network.

    Hope this helps

    Many thanks Krister and Mike, I passed your advice onto the IT support team who is hosting the server for the OC Community Edition.

     Will let you know the progress.

     Best wishes, Yueqing

    You can tell your IT support team that they should follow the OpenClinica install instruction to the letter, If they do, it will always work, locally as well as remotely. I know IT people are special "bunch" that have their own ways of doing things. That won't always work. If they follow the instructions it take less than 30 minutes to install OpenClinica and all its support programs, but you have to do it right!! If it does not work, you same a lot of time by simply erase everything and start from scratch.

    God luck
