    Unable to run unreleased commands within Jython

    Gavin Egli Jan 10, 2012 8:53 AM

      Hi everybody!

       

      I am trying to run unreleased commands within Jython, unfortunately without any luck yet.

       

      My installation contains Jython 2.5.2 and BL 8.0 SP10.

       

      I have found some discussion around unreleased commands in here and have set  a jvm argument in bljythonexe.cfg to be

       

      jvm.arg=-Dcom.bladelogic.cli.debug.release-only="false"

       

      In that discussion bljython.cfg was mentioned. Somehow after installing RCP locally no bljython.cfg gets created. The only similar file I have is bljythonexe.cfg.

       

      Now everytime I run my command from within Jython I get following output:  

      2012-01-10 13:49:41,701 -  BladelogicXMLRpcService - Thread - ERROR - chw12345675 : 
com.bladelogic.cli.factory.CommandNotFoundException: R: Cannot find command : PropertySetInstance, 
findPropertySetInstanceByDBKey CHM06065743.ch.ad.hedani.net - - 
[10/Jan/2012 13:49:41] "POST /RPC2 HTTP/1.1" 200 -

       

      This is how I run the command(s) from Jython:

       

      propertyInstanceObject = blcli_run(jli, ['Server', 'printPropertyValue', hostname, customPropertyClass])
dbKey = propertyInstanceObject.returnValue         
instancePath = blcli_run(jli, ['PropertySetInstance', 'findPropertySetInstanceByDBKey', dbKey])

       

      Would be very appreciated if someone could give me a helping hand.

       

      Cheers

      Gavin

          What is the complete error retunred, You can find errors in blcli.log which should be created in :

          Unix - $HOME/.bladelogic

          Windows/<user>Application data/BladeLogic

          Also, for windows the bljythonexe.cfg is the correct  file used.

            Hi Rohit,

             

            the only new line I see from the blcli.log is this - might be because I'm running the Jython script from within a Webservice?:

             

            10 Jan 2012 16:49:11,494 WARN [MESSAGE] appserverHost option is not supported [/MESSAGE]

             

             

            From an earlier run I see this though:

            I can run released commands without any issues.

             

            Thanks

              what bljythonexe.cfg did you modify?  on what system?  and how exactly are you running this ?  eg, where is the jython install, where is the WS running, etc.

                Hi Bill,

                 

                I modified the bljythonexe.cfg in C:\Program Files\BMC Software\Bladelogic\8.0\NSH\br on my local Windows 7 x64 system.

                That's where I installed the Bladelogic Automation Console to.

                 

                The webservice .py script runs on my local machine too - and connects to one of our testing appservers as soon as needed. (I.e. for running the blcli commands).

                  so you make a WS call to a jython listener that's listening on the local workstation.  that calls bljython and then that makes a request to bbsa ?

                   

                  why not just use the WS in blade on the appserver? 

                   

                  let's take the WS out of the picture.  can you run any of the unreleased commands straight through jython on your local system ?

                   

                  also - i have a bljython.cfg on my system - do you also have that? try modifying that file ?

                    Hi Bill,

                     

                    thanks for your help.

                     

                    I guess the WS was only integrated into the appserver after 8.1 right? We are still running 8.0 SP10 and will use the appservers WS in future I guess. But otherwise you got it correct. Since the jython script is listening we open up one jvm for all the commands we process and shut it down at the end then.

                     

                    No luck running it on my local system neither. I get the same error when trying to run it locally..

                    I don't have any bljython.cfg after the installation of the 8.0 SP10 (1014) Automation console I'm afraid. But I also can't say why it's missing - I tried reinstalling the Automation console and also jython several times.

                     

                    What I tried is copying the bljythonexe.cfg to a bljython.cfg file which didn't change anything - after that I also tried replacing bljythonexe.cfg instead of having them both but that caused bljython not to run anymore.

                     

                    Basically we will need you guys to integrate that PropertySetInstance findPropertySetInstanceBeanByDBKey command to the released commands soon or later anyway - what would the process be to get a requirement for it? Should I inform support and ask them to open a requirement with you guys? You might be able to know an other way of doing what I need, I want to retrieve the full path (Class://class/subclass/subclass/instance) to an instance in the custom property dictionary in order to delete it by server object. (We have several instances linked to every server object - when decomissioning the server object we want to get rid of the instances too) Thanks Gavin

                      open a ticket for the rfe w/ support.

                       

                       

                      for the commands, i have this:

                      jvm.arg=-Dcom.bladelogic.cli.debug.release-only=false

                      not

                      jvm.arg=-Dcom.bladelogic.cli.debug.release-only="false"

                       

                      and i can run unreleased commands.  i could not run the unreleased w/ the double quotes, i can w/o.

                        Hi Bill and everybody,

                         

                        to follow-up on this topic I have set my bljython.cfg as suggested by Bill and I still can't access unreleased commands, either with double-quotes or with no quote at all.

                         

                        I'm using BSA 8.3 sp2

                         

                        Thanks for your help.

                          Hi all,

                           

                          thanks to Bill Robinson, here is solution to my problem :

                           

                          for UNIX systems, bljython.cfg is not used and one needs to modify directly the "bljython" script to add

                           

                          -Dcom.bladelogic.cli.debug.release-only=false

                           

                          to the java command line.

                            Another way to get around this is to set this property directly in the Jython-scripts:

                             

                            [...]

                            from java.lang import System

                            [...]

                            System.setProperty("com.bladelogic.cli.debug.release-only","false")

                            [...]

                             

                            which essentially should do the same.

                             

                            The drawback: you have to include it in each and every script

                            The benefit: you are independent of whatever config-file
