DAQ 3 System Upgrade Status

 

April 23, 2002

 

VME systems Configuration

 

Currently operating with vxWorks Tornado 2.0.2

 

Compiler:  gcc 2.7.2

 

Orbix/E  2.0

 Embedded C++

           

 

  Status:

 

  All subsystem servers ( dcm, gl1 , timing ) have been rebuilt in this operating environment.

 

  System tests have been conducted to varying degrees, the based on the conversions of the application programs.  More details later.

 

  All servers were converted to use the OMG nameserver, although each is also functional with the previous nameserver.

 

 Observations:

 

 Stricter compiler standards resulted in more than a few code changes to compile and run successfully.

 

Effort was made to fix warnings, however, many still remain as the main function was to identify major issues and have an operational system in place.

 

Code modifications were made to correct for changed CORBA standards.

 

Orbix/E concurrency model requires thread safe operation on shared code as multiple clients operate in separate threads.

 

 

Desireable to migrate to gcc 2.9.6 compiler due to lack of desireable C++ features which restrict certain IDL constructs.

Wind River is scheduled to support this version compiler this June/July.

Currently arranging for a beta version.

 

 

 Of those tested, only one function failed to operate successfully so far.

 

SUBSYSTEM MIGRATION STATUS

 

 

DCM

 

Map updated for T2.0.2

 

Dcm server and utility functions built.

Standalone dcm application successfully executes dcm download and

Initialization functions.

 

Dcm  CORBA server was upgraded and built.

 

          Registers with OMG nameserver

 

TODO:

 

Finish conversion of run control to test  dcm functions

 

GTM STATUS:

 

VxWorks server converted and running under T2.0.2

 

Gtmcommand application built and run with new server

 

GTMgui built with JDK 1.4 and run with new tm server.

          - not extensively tested

 

Test program results by JH produces

 JH ran multiple client instances of gtmcommand 

 

Errors in memory address when running multiple clients

 

 

TODO:

 

Make tm server thread safe

 

 

 

 

GL1

 

GL1 server built and running under T2.0.2

 

Most functions successfully tested

 

-         problem with GL1_I::LV1_rdmonfifo

-         possible memory limitation  - currently under investigation

 

 

 

Application Program Status

 

Operating environment

 

Solaris:

 

Orbix2000

  CC 5.1 C++ compiler

  Upgrading compiler to C++ 5.2

 

  JDK 1.4 Java environment

    Jdk 1.4 Idlj compiler

 

Linux:

  Orbacus 4.1.0b1

 

  Built Orbacus 4.1.0

   Currently upgrading to this version

   Requires code rebuild only so far.

 

NT

 

Orbix 2000

Visual C++  6.0

( Is  there a desire to move to gcc? )

 

Build Environment

 

VxWorks kernels are located in /export/software/lic/wind/Tornado2.0.2_ppc

 

Source /export/software/lic/wind/setupT2020env.csh for Tornado 2.0.2 environment variables.

 

Currently building in private area

 

Propose creating R4.0.0 version for installation

 

 

 

Issues:

 

Current vxWorks compiler lacks feature needed by JDK 1.4 IDL compiler.

Results in an Object ID difference.

 

Option:

  Workarounds available to make references compatible.

  Will test beta vxWorks compiler soon.

   Use Orbix2000 jidl compiler ( JDK 1.3 compatible )

 

 

 

 

 

Client Application Status

 

 

Built CorbaUtility C++ libraries

Built Java CorbaUtility packages

 

Status:

 

C++ libraries are being used by test and online applications

Java jar libraries are being used by built online Java applications

 

GL1  APPLICATIONS:

 

Application

Status

gl1gui

Built most functions tested

Bbcgui

Built , run but not tested

genll1gui

Built , run but not tested

GL1rc

Built , run some functions tested

 

 

 

 

 

 

 

 

ARCNET SERVER

 

Built server with IIOP protocol and libraries.

 

Status:

  Not yet tested.

 

Code was added to migrate server to Linux

 

Status:

  Not yet built under Linux.

  Needs Linux ARCNET drivers.

  Will build server on Linux ASAP.

 

General Utility functions:

 

Nameserver manager , browser

 

 Currently being ported.

 

PARTITION SERVER

 

Currently migrating server application

 

RUN CONTROL

 

Need to convert to use common utility libraries.

Currently migrating server and Java gui

 

EVENT BUILDER

 

Design goal is to provide parallel server startup and initialization within 1 minute.

 

Will build prototype  servers for demonstration of  start, initialization and  restart operations with new system servers.

 

 

 

PHENIX MESSAGE SYSTEM

 

Is implemented with OMG Event Service

 

Previous message generators and Message consumer/ display application was ported to work with Event Service

 

Existing Message Structures work with Event Service.

 

Applications sending / receiving messages have been running for over a month.

 

Will test further for failure modes as time allows.
