Subject: RE: Alarm Server start problem and how to compile JCA on Fedora20 64 bit system ?

First, thanks for your respond, the problem have been solved !

I have another quesion about alarm system to consult you:  
I started the epics IOC and want to set up the alarm monitor with PV name: SXFEL:RP:Gamma:Real:Dose.
To do this, I configured alarm server with PV name SXFEL:RP:Gamma:Real:Dose:alarm which is imported from the test.xml file (the details are list below) and then I started the alarm server and Control System studio(CSS). 

In the Alarm Table in CSS, after waiting for server connection, Current Status of the PV name SXFEL:RP:Gamma:Real:Dose:alarm in table shows no Connection; Current Severity and Alarm Status all show No Connection. Others items in table show UNDEFINED.

and also the alarm tree with PV name shows:
PV:SXFEL:RP:Gamma:02:RealDose:alarm (UNDEFINED/No Connection, UNDEFINED/No Connection)

Below is my test.xml file in details which imitate "org.csstudio.alarm.beast.configtool/demo/demo.xml". By the way, what is the <latching>true<latching> mean?
<config name="agm12011-alarm">
       <component name="SXFEL">
                <pv name="SXFEL:RP:Gamma:02:RealDose:alarm">
                       <description>Detector1</description>
                       <latching>true<latching>
                       <annunciating>true</annunciating>
                </pv>
        </component>
</config>

I think I miss something and how to set up the alarm for the PV. 
Could you please help me and thanks in advance !

You concluded correctly that the alarm server cannot find the JCA binary.


You have two options:


1) Tell the alarm server to not use the native JCA binary, but instead the pure java CAJ implementation that's already included. To do that, put this into the -pluginCustomization config file:

org.csstudio.platform.libs.epics/use_pure_java=true


That has actually been the default since summer 2012, see
https://github.com/ControlSystemStudio/cs-studio/blame/master/applications/alarm/alarm-plugins/org.csstudio.alarm.beast.server/plugin_customization.ini





2) Get the JCA binary and property install it.
If you decide to change the default alarm server setting because you prefer the native JCA library, that's fine, but then you need to build it and assert that it's found.

For building it, you'll have to check the ant file and the config files that come with the JCA sources.
You're likely missing some environment variable like EPICS_BASE_RELEASE.

For using it, you need to add the location of the JCA and EPICS binaries to the PATH (windows), LD_LIBRARY_PATH (Linux) or DYLD_LIBRARY_PATH (Mac OS X).

Subject: Alarm Server start problem and how to compile JCA on Fedora20 64 bit system ?
 
hi,

I have two questions to consult you:

1)  I enconter the following error messages (the details are shown below) when I start the Alarm Server by using the following command line on fedora20-64bit system and It seems that I miss JCA package , therefore I want to compile the JCA zip file that support for 64bit system on website: https://sourceforge.net/p/epics-jca/jca/ci/default/tree/
Is my reasoning right ?

Here are the command line and error messages in details for question 1):

2)  I also encounter errors when I compile unzaipped JCA package with ant command and the error message is:  fatal error: epicsVersion.h: No such file or directory
It seems some configuration should be made with config.linux-x86_64.properties file in config folder.
But i don't know how to do.

Could you please help me and thanks in advance !
