Pinned topic BPM 7.5 Linux and Process designer

‏2013-05-09T08:42:43Z |

Trying to install and configure IBM BPM 7.5 for a demo. After many hacks and almost 2 hours of installation and again some hacks to correct a wrong firefox version check in installation, I got a link to Process designer. It turns out that Process designer supports only windows. Not a great news for me. But then I thought that means there should be a way I can install the process center in Linux and the designer in windows.

When I install and start process designer in windows it asks for a username/password. I have no clue which username and password because I did not create any. I tried to give admin/admin, but it kept saying it cannot find process center. That's logical because I did install Process center on a linux box and process designer on a windows box. I really love to hope that process designer installed on windows can connect to process center installed in Linux. But I cannot find any logical place I can configure this connection. 

 

Can someone help me and let me know if it is possible to install process designer in windows and connect to process center in another machine? If yes, how can this be done. If no, then ..............................................

    The easiest path, assuming you want Process Center on another box, or running in non Windows OS is to do the following -

    1. Install the process center.  It is important to note the Admin password you give it.  If you don't remember and didn't change it, it is likely a combination of tw_admin/tw_admin or admin/tw_admin or admin/admin
    2. Start up the process center.
    3. Go to your windows box and connect to the process center.  By default this will be http://machineYouInstalledOn:9080/ProcessCenter.  The installer should have told you that at the end if you used a UI to install.
    4. Login with the the admin user/password.
    5. On the right hand side there is a Process Designer link.  Click on it and download.
    6. Extract the zip file.
    7. Open up a command line.
    8. Go to where you unzipped the Process Designer.
    9. Run the correct command line command (there is one for if you are running with admin access and one for non-admin)

    It seems like you might have a bit of a problem running a demo though if this is all new to you...

      Thanks, but I'm afraid it does not answer my question.

      I do not "want" to install process center and process designer in different boxes, I'm forced to like everybody else who wants to use a Linux installation. Because process designer is not supported in Linux (at least till 7.5). I did write this as well as the steps I followed which included downloading the process designer and then installing in the windows machine. When I start the process designer and gives the username password it complains that it cannot find the process center. My question is how I can connect process designer to the process center. Or one step back, how to work a process designer work with a process center deployed in a Linux machine

      I'm not accessing any demo and I'm not new to IBM BPM.

        We do not have any Linux-based Process Designer in the works.

        Please use the "Request For Enhancement" process to register your vote to help raise the visibility of this issue.

        The simple answer to your question is to download your Process Designer to your Windows box from your Process Center. 

        The PD install downloaded from your Process Center should contain all of the correct configuration settings - But of course that means your Process Center's IP address can't change.

        The problem you describe certainly sounds like the IP address isn't correct for some reason - or there's some sort of Firewall issue.  Very strange.

          Thanks. That solved the mystery. When I download the server address is already configured. I love the server address magically coming in the downloaded software, but these intelligences cost more time than the use. We are not expecting Apple fans to install IBM BPM :). At least if the message said it cannot find the server at http://myhost.... then I could have guessed.

          Anyway, now I now why it is telling me that the server cannot be found.

           

          PS: Meanwhile I tried to work with BPM 8.0.1 because the documentation of that product said that all components are compatible with Linux (Whereas BPM 7.5 documentation explicitly said that ProcessDesigner is not supported). Another inconsistency. I have installed many products for evaluation, but my experience with IBM BPM products is really low. Wonderful story starting from 7.5 version not able to validate firefox 10.0 version, not supporting 64 bit libraries and the extremely slow installation process. While installing 8.0 it asks me for DB2 user creation, great, but it does not validate the user name and fails in between installation. In most projects installation is the first step in a bid or product selection process. Giving a bad installation experience is not a great idea for business. Can I formally raise these issues with some contact?

        Double check the eclipse.ini file that is located where the process designer is installed.  There is an entry that tells it where to connect to the Process Center.  The value there should be the same one you are using in your browser but I have seen that not work in some cases.  I actually change mine all the time for different customer's Process Center installs...

        As John mentions, there will be a problem if the name you used when you installed the Process Center is one that the client machine will not resolve, as this name gets placed in several configuration files and is handed to the various clients to do callbacks to the server.  I don't agree with this design, but it is how it works today.  One hack I've used in the past when this has happened and I haven't had time to fix it is to put that name in the etc/hosts file of the client so that it resolves.  If you do this please remember you did, as it is likely to cause you problems if you go to a different windows box.

          This is what I see in eclipse.ini - Dcom.ibm.bpm.processcenter.url=http://localhost:9080

          I wonder how this can ever be true for a Linux installation because Process designer cannot be installed in Localhost. The basics of this idea to give a pre-configured url is wrong. The least they could do was to give the actual host name. 

          I hope changing the ini file will be fine.

            If you installed against local host (which some people do on windows boxes) then that is where the server thinks it is.  This is also the value you will see if you install Process Designer using Installation Manager as opposed to using the command line script I mentioned earlier.  It is basically the default value that in an ideal world would be replaced by your script.

            Note that using Installation Manger is the only way I have found to successfully install multiple versions of the Process Designer on the same client, so if you need to do something like that, it is the right way to go, but you have to correct the url that you noted above.

              I know it is the most common to use localhost :). But because a Linux version does not support process designer it is the least common option (absolute zero) for a Linux installation. And the fact that configuration of url ( I don't even know changing it will work) is hidden inside eclipse.ini file and not asked while installation makes it even more illogical.

              PS: Another irritation was that process designer installation just went ahead and installed the system in the C:\IBM folder. I do not think that's the way things are done. I have to be given an option to decide where I want to install it. Maybe IBM should spend some more time correcting basic problems before releasing newer and newer versions with features. The technical people do have a say and not everything is decided by suits looking at power point slides.

                Well, I'm getting a bit lost in what install option you followed.  If you installed from the command line using the download, then it _should_ have replaced the localhost with the correct URL, so I'm not sure why it didn't.  localhost is the default in the file simply because there is no way to get a correct default.  My basic understanding is that the Process Designer is installed and then the eclipse.ini file is updated with the correct values (since they will be different for every process center).  So localhost is simply a placeholder.  It could be http://replaceThisWithRealValue:9080.  It would still be wrong.

                The previous incarnation of the Process Designer (called the Authoring Environment) used to give you the ability to change this value when the Process Designer started up, but for some reason the product management team decided to get rid of that option.  I'm not clear why.  When this was true, you didn't have to touch eclipse.ini to change the value, but that feature was pulled.

                Now if you installed using the installation manager, you do have the option to choose where you want to install the PD, so if it annoys you not to be prompted for an install location, just use the Installation Manager.  There is a basic tradeoff going on here, wanting to let people who really don't care about these details get up and running quickly vs. letting the people who want to have a say in each configuration choice being able to do so.  It is a hard balance to strike.

                  I double clicked on the *.exe file and that's how it got installed. I did not see any message, just a cmd prompt. Afterwards I realized it just installed itself. Was kinda surprised. Now, I'm refreshing the whole installation with 8.0.1. Let's see how that will be

                   

                  PS: When IBM BPM installation fails it does not cleanup. There are no validations for the inputs. Passowrd policies make the installation fail half way. Once it failed with reason "instance password missing" - I wonder what it was and why it did not tell me if I missed a field. There is no option to press back and see what was missing. Only option to get back from the start. Every time I have to cleanup the install directory. Somebody should tell the product managers that the technical people who has to install the software can also influence a buying decision. Yes, we can :)

                    If you are evaluating the IBM BPM product you should most certainly talk to your local IBM rep.  You should not be given the product and be left to get on with it.  Rather, IBM support specialists should be able to assist you with all your questions, comments and, at a minimum, get you to a working environment where you can start to evaluate the functions of the product,  IBM BPM has a lot of moving parts and it can be tricky to get them all working together.  Thankfully the documentation is pretty clear but there is a lot of it.  A consumer who decides to go with IBM BPM is strongly encouraged to attend class and read all the manuals carefully.  Installing and configuring IBM BPM isn't always a one-click-and-done proposition.  However, once installed and up and running, using Process Designer to described and run business processes is a pretty seamless activity depending on what you are building.

                    I work for IBM and my job is to provide pre-sales technical support to evaluators like yourself.  I am engaged through your local IBM reps.  We just need to make sure that all the relevant folks are talking and working together.  It dissapoints me to hear that you are having a bad experience with the basic installation and I can fully believe that would leave a bad taste in your mouth for further examinations.  Prod your IBM rep and ask for assistance to get where you need to be.  You are for sure not on your own in your examinations of the product, IBM is here to assist and help.

                    As for technical folks being decision makers ... you betcha!!!  Fully on board with that.  There is a vision of what "BPM" means to a company and in many cases it starts with business leaders grasping how it can help but when the rubber meets the road, it will be some vendor's product that will be utilized to achieve that goal.  IBM knows that it falls to the IT staff to deploy and implement some portions of the BPM story and we also realize that IBM BPM is not the only product competing for your business.

                      Thanks for the reply. I will surely involve IBM support or IBM representative when it comes to the evaluation. I'm not going to let my experience affect the evaluation, but I'm just making a point on technical guys still has some influence.

                      I'm not looking for a one-click install experience. If I get a good documentation that explains the process and requirements I can work with it. I do not see these steps in the documentation. There are some basic expectation from an installation process. That's what's making me comment. I'm not yet in a state to get official support. Once I get it then I will start reporting these issues formally with expectation that the product will improve.

                      I have to get an installation first to make sure that the environment is ready for some demos. I need it also to refresh my IBM BPM knowledge.

                    If the ".exe" file you are talking about is the one you downloaded to your windows box from the Process Center, that doesn't actually do the install, it just lays down the files that are required to do the Process Designer install.  You then need to run a command line script to get the process designer fully installed.  This is covered in this info center entry.  While that is the 8.0.1 link the process was the same in 7.5.

                  I need some help.

                  Installed 8.0.1 in Linux box. After that the firststeps was launched. I verified installation through that, that worked fine. I could also access the process center through firefox and login with the username and password. Then I had to restart the linux machine. After that I started the <installationpath>/profiles/ProcessCtr01/firststeps/bpmPC/firststeps.sh and started the server through that. But now I cannot login with the username/password I used before. :). What to do now? I'm stuck.

                  There are many many firststeps.sh, but I think this is the correct firststeps.sh. I cannot find any documentation on what to do after an installation. I know the standard advice is to contact IBM support. But I'm not in a stage to contact the support. First I need a space to play around. If I'm the first person to ever try the Linux installation, please do let me know. I will not try this.

                    First steps is not how I typically start my servers.  On linux do the following -

                    1. go to <install directory>/ibm/BPM/bin
                    2. run ./startServer.sh <your server name>

                    I've assumed here you did a stand lone install and not an ND install.  The server name is the name that you used when you walked through the installer.  Likely something like "ProcessCenter01".  If you aren't sure of the name, and you did a stand alone install you can double check by going to <install directory>/ibm/BPM/profiles/<profile you are checking, should only be 1>/config/nodes/<node name>/cells/<cell name>/servers  In there there should be only one directory and that is the name of your server.

                    node name and cell name for a normal quick install are something like "node01" and "cell01" but again, I would expect there to be only one.

                    If you did an ND (network deploy) install, let us know and someone will dig up the same call.  I think it is ./startNode.sh but I'm not certain...

                      Thanks for the reply.

                      ProcessCenter01 is the name of the profile. Server name is "server1". I did try to start the sever from the <installdirectory>/bin folder with the argument "server1". But the same problem with the username/password. It is not taking the username/password combination that I gave during installation. The same combination which I used to login the first time after the installation (through the first steps). I'm sure about the username password because the first time it happened to me I wiped out the whole machine ad did the installation again, because I thought I made a mistake and really forgot the password. But this time I'm sure that that's not the case.

                      It is a standalone deployment. Can you check if I can reset the username password through command line (or other configuration)? I'm very very sure that the username/password because I was very careful giving it.

                        Hi,

                        I think your database didn't start after restart.

                        BTW, the standard installation of DB2 has not autostart settings.

                        Check it.

                        If your database is not accessible, BPM cannot read account information.

                        Vlad.

                        PS. At last I can edit my post!

                          Good call Vlad.  If he's right, you should see errors attempting to connect to the DB in your SystemError.log file.

                          Ojhhh. That was logical. I should have thought about what was missing after a restart. 

                          I'm sure everyone this will solve it. I just let myself be distracted by the username/password is wrong message instead of a system error. 

                          Thanks a lot. I will check and update back.

                          Yes, it worked after starting db2. I can now login to the process center.

                          The trouble now is connecting the ProcessDesigner, installed in a windows machine, to the ProcessCenter running on the other machine. As I explained earlier, I did download the ProcessDesigner from the Process center console. After I installed it the eclipse.ini file had the url as http://localhost:9080, which is not the hostname I configured for the process center machine. I tried to change the url to the correct ipaddress (also tried with a hostname), but when I try to login to process designer I got the following message

                          Unable to establish a connection to ProcessCenter. Please check your connection settings and verify that the server is running

                          I have verified that I can connect from the machine in which Process Designer is installed to the Process center with the http url (hostname and ipaddress) and I can also use login. I do not see any log file or any place I can debug what is happening. I used the eclipse.exe file to start process designer.

                          Do you know what I can do to change the server url (if eclipse.ini is not the right place). Or do I have to do something at the ProcessCenter side so that the url comes right.

                            This time I did not let logic distract me. I just had to think. The url that comes in the eclipse.ini file is the browser url through which I downloaded the installable file. Now I put the correct hostname and downloaded the ProcessDesigner file and installed it.

                            But unfortunately I still get the same error

                            Unable to establish a connection to ProcessCenter. Please check your connection settings and verify that the server is running

                            I made sure that the url is accessible from the machine. Also the firewall at the sever side is switched off. Can I check something else to make sure that other ports are also open? eclipse.ini file is attached with this post. I also tried restarting the whole process center machine. I also checked to make sure that the port 2809 of server is accessible from the machine in which I installed ProcessDesigner.

                             

                            I also tried creating new user in the ProcessAdmin page, adding it in the ProcessConsole and then using that user to login in ProcessDesigner. But still the same mesage. I also noticed that when the ProcessCenter machine is not accessible (for example firewall), the message that comes is different. That gives me a feeling that there is most probably no problem in getting a connection. But maybe I'm wrong.

                              On your server there is a file "TeamWorksConfiguration.running.xml"  You can probably find it in <install dir>/ibm/BPM/profiles/ProcCtr01/confi/cells/Cell01/nodes/Node01/servers/server1/process-center

                              In there you will find a number of entries that have urls in them, for example <images-prefix>

                              These URLs are used to do callbacks to the server.  The question is what server name you see in there for those URLs.  I'm really hoping it is either the server's machine name, its ip address, or its FQDN.  If it is localhost, then we know why your PD downloaded with the wrong value, and you are going to have to fix those entries (in the source files) before this will all work.

                              Also - are there any firewalls between you and the server?  The PD depends on a bunch of other ports to communicate with the server besides the http communication.

                                The url that comes in the PD eclipse.ini is the url with which I access the process center while downloading PD. I did mention that before. If I give xyz as the host name in the http url, it will be even xyz in PD. 

                                But the file you said in the path has the following entries:

                                 <images-prefix>http://localhost:9080/teamworks</images-prefix>
                                 <portal-prefix>http://localhost:9080/portal</portal-prefix>

                                Path: /opt/ibm/BPM/v8.0.1/profiles/ProcCtr01/config/cells/localhostNode01Cell/nodes/localhostNode01/servers/server1/process-center/TeamWorksConfiguration.running.xml

                                But the hostname I configured in my server is different. I'm sure that's not what IBM BPM takes.

                                As i in mentioned in my previous post,  there are no fireWalls between server and PD. I checked a number of ports. I did that analysis already if you read my post.

                                Any idea what I can do next to solve the problem?

                                  Sorry for the long delay.  It looks like somehow through your setup the wrong values got put in the configuration files.  Unfortunately some of these files are from the tool that existed before the IBM acquisition of Lombardi and do not yet update from WAS console or commands, so you have to change the values manually. 

                                  Based on where you found the TeamWorksConfiguration.running.xml, if you look in there there is a directory called (I believe) config and in there is a system directory.  In that directory there will be a number of files named ##XYZ.xml that are used to create the TeamWorksConfiguration.running.xml when the server starts up.  You will want to go through those and find the references to http://localhost....  And change them to be the right value for you server.

                                  I was hoping to find a document for server rename that would call out all of the changes you needed to make, but was unable to find one.

        You don't really provide much information to work with.

        Connecting a Windows Process Designer to a Linux Process Center is very common configuration, perhaps the most common. So if you are having problems, its something specific to your environment. Firewall? Misconfigured client? Network? DNS? Misconfigured server? Problem with the DB/auth system? Hard to say without any information.
