[Cs-studio-users] Using the XY Graph: One trace extends beyond the rest

[Grelle, A. L. <ag...@an...>]

Good Morning,


When I am using the XY Graph widget, I would like all of the traces to display their values for the last "N" time steps. To test this, in setting up the traces, I put the Buffer Size to "100" and the Update Delay to "0" for each trace, where the x-axis is an 'ao' PV with the current time in seconds.

One trace seems to extend well beyond all of the others, and I cannot figure out why - even with identical settings for all traces - there is always one trace that is not displayed the same as the others. Any ideas?


Thanks in advance,

Austin Grelle

Ok, I switched to JNI and everything seems to work smoothly now :-)

I cannot reproduce the restart issue. I'll send you a stack trace if I
run into it again.

Thanks a lot,

Martin

Re: [Cs-studio-users] ArchiveEngine does not reconnect channels

[Kasemir, K. <kas...@or...>]

Hi:

The does-not-reconnect issue is different from the restart issue.

So on the reconnect: Are you using the JNI JCA or the pure Java CAJ?
With JNI, and having a caRepeater running, we do not see reconnect issues
at the SNS.
With CAJ, we do see them all the time. So on the accelerator network, we
stick with JNI.

On the restart:
It could be stuck somewhere.
Pity that there's no error message that would tell us more.
If that happens again, you can use

 kill -QUIT {PID-OF-Engine's JVM}

to create a Java thread/stack dump.
It might help me to see what the engine is doing: what thread is where,
are there any deadlocks.

Thanks,
Kay

[Cs-studio-users] ArchiveEngine does not reconnect channels

[Martin K. <ko...@ik...>]

Hi,
I'm using ArchiveEngine 3.1.1.201209292342. I often see EPICS channels
that do not reconnect after an IOC is stopped for some
minutes/restarted. There is no message about this on the ArchiveEngine
console. Opening the restart page via the web console results in the
following messages on the console:

2012-12-12 14:15:36.200 INFO [Thread 10]
org.csstudio.archive.engine.Application (start) - ArchiveEngine ending
2012-12-12 14:15:36.201 INFO [Thread 10]
org.csstudio.archive.engine.model.EngineModel (stop) - Stopping scanner
2012-12-12 14:15:36.272 INFO [Thread 12]

2012-12-12 14:15:36.272 INFO [Thread 10]
org.csstudio.archive.engine.model.EngineModel (stop) - Stopping archive
groups

It seems the ArchiveEngine does not really restart (it still shows the
old uptime on the web front-end and does not print the usual messages
during startup). The web interface still says "status: STOPPING". This
did not change after 15 minutes...

Any ideas?

I'm using the code from the SF cs-studio-3.1 branch:
$ hg par

So I should be up to date. See the attached file for my changes (only

> then obviously we haven't really made it work with Postgres again.
Can you please check that I'm using the right branch
(http://cs-studio.hg.sourceforge.net/hgweb/cs-studio/cs-studio-3.1/)? If
it is the right one, I'm sorry to confirm that the problem still occurs...

What can I do to help fixing this issue?

Re: [Cs-studio-users] ArchiveEngine: schema with PostgreSQL

[Martin K. <ko...@ik...>]

Hi Kay,

PostgreSQL supports schemas but if you don't specify one, the 'public'
schema is used automatically:
http://www.postgresql.org/docs/9.1/static/ddl-schemas.html#DDL-SCHEMAS-PUBLIC

So you're right: PostgreSQL does not need a schema but schemas _can_ be
used and the question remains:

Re: [Cs-studio-users] ArchiveEngine: Write Error

[Kasemir, K. <kas...@or...>]

There are two different errors in the log.

One is about CAJ UnsupportedOperationException.
That one shouldn't matter.
We've added support for the DBE_PROPERTY event to the CSS code, but CAJ
doesn't understand it except for the latest version.
So in the snapshot of the sources that you have, it complains but should
still "work".

The other error is a problem:
For better MySQL optimizations, we've started to mark RDB connections as
"read only" whenever possible.
Then Lana from the ITER project, where they are using PostGres, noted the
very problem you see:
Postgres doesn't like it when connections are changed to/from readonly at
certain times.
In principle, Lana went through and updated all sources to also work with
Postgres again.
If you still see these problems with the latest source snapshot from the
source force "cs-studio-3.1" repository or from

https://ics-web.sns.ornl.gov/css/updates/apps
(look for 3.1.0a binaries & sources)


then obviously we haven't really made it work with Postgres again.

Thanks,
Kay

[Cs-studio-users] ArchiveEngine: Write Error

[Martin K. <ko...@ik...>]

Hi Kay,
I ran into some sort of a problem when I updated the ArchiveEngine from
3.0 to the 3.1 branch. The database is still the same, I only replaced
the ArchivEngine directory. When I start the Archive Engine it connects
to the PVs and the RDB successfully and reads the list of channels
correctly but according to the PostgreSQL log file it never tries to
INSERT data (although the right username "archivewriter" is used). The
Archive Engine web frontend says "Write State = Write Error" but it
doesn't say why. How can I find out what's going wrong here? There are
some exceptions (see attached log file) but I'm still not sure if they
are the cause or a result of this problem.

Any help is appreciated

[Cs-studio-users] ArchiveEngine: schema with PostgreSQL

[Martin K. <ko...@ik...>]

Hi Kay,
what's the right way to specify a schema in the configuration when using
PostgreSQL? Using the org.csstudio.archive.rdb/schema option in
org.csstudio.archive.engine/plugin_customization.ini or using the URL?
With version 3.0 I successfully used the schema option and a URL without
a schema. But the documentation
(http://cs-studio.sourceforge.net/docbook/ch09.html, last sentence) says
something about specifying the schema in the URL instead. I'm not sure
if this is correct for PostgreSQL...

Best regards

Re: [Cs-studio-users] Question about Data Browser

[Kasemir, K. <kas...@or...>]

Hi:

For the record, the issue was that the ArchiveEngine had stopped.

Like any RCP app, the ArchiveEngine, AlarmServer, ... use a workspace.
It can be set via
   ArchiveEngine -data /path/to/engine_workspace

Only one program can use a workspace at a time.
For non-GUI programs, the only useful thing in the workspace
may be the .metadata/.log file that might provide error messages.

Thanks,
-Kay

[Cs-studio-users] Question about Data Browser

[Florian F. <fl...@ep...>]

Dear all,

I'm archiving the values of my EPICS PVs with BEAUTY and store them in a 
postgresql database. This database is also used as archive data server 
for the data browser. The PVs are triggered periodically every 10 seconds.

In the Data Browser however, the first archived value appearing for any 
PV in the strip chart is approximately 24 hours old, although the 
database contains many entries for the time in between.

Is this the normal behavior? Can this be changed?

Best regards,
Florian

Re: [Cs-studio-users] Authentification module

[Florian F. <fl...@ep...>]

Hey,

Yes, I already figured this out. In the Documentation about auth&auth it 
was written
that one has to set the extension point for the loginModule. So I 
thought it has to
be set in my own product plugin.
I already changed this and also found the reason for my problem.

Now my product seems to work. Have to test it next week.

Best regards and thanks for the help,
Florian

Not sure what exactly you mean by "<I> set the extension points in my
product plugin".

If you simply include the plugin org.csstudio.platform.jaasAuthentication,
its plugin.xml will tell Eclipse that it has a "loginModule" for
the extension point org.csstudio.auth.loginModule:

osgi> pt -v org.csstudio.auth.loginModule
Extension point: org.csstudio.auth.loginModule [from org.csstudio.auth]

Extension(s):
-------------------
null [from org.csstudio.platform.jaasAuthentication]
   <loginModule>
      class =
org.csstudio.platform.internal.jaasauthentication.JaasLoginModule
      id = org.csstudio.security.jaasAuthentication.jaasLoginModule
      name = JAAS Login Module
   </loginModule>



Likewise, if you simply include the plugin
org.csstudio.sns.dummyAuthorization,
its plugin.xml will tell Eclipse that it has an authentication provider.

You don't need to
1) Add those plugins to your product
2) _and_ set the extension points in your product plugin
Just 1) is all you do.

So maybe by doing 2) as well you actually registered the same loginModule
twice, and that's what's causing the error
"Found multiple login modules"

-Kay

Re: [Cs-studio-users] Authentification module

[Kasemir, K. <kas...@or...>]

Moin Florian!

The 'API' for auth & auth is defined in org.csstudio.auth.
You can only load one implementation for each of the loginModule
and the authorizationProvider.

But it looks like you end up with more than one:
2012-02-29 17:31:50.904 SEVERE [Thread 1]
org.csstudio.auth.internal.usermanagement.LoginContext (getLoginModule) -
Found multiple login modules

So you need to figure out which ones you have loaded.


Start CSS with a command-line option "-console".
That way you get the OSGi console on Linux and OS X.

On Windows, the cmd.exe terminal doesn't really work,
so use
  css.exe -console 9876

and then use telnet to connect to port 9876 to get to the console.
(You can also use -console <TCP port> on Linux and OS X,
 but you don't have to)

In the console, try "help" to see all the commands, and then see
what's loaded for the extension point "org.csstudio.auth.loginModule".

In my case I see that exactly one implementation is loaded,
and it's provided by the plugin org.csstudio.platform.jaasAuthentication:


osgi> pt -v org.csstudio.auth.loginModule
Extension point: org.csstudio.auth.loginModule [from org.csstudio.auth]

Extension(s):
-------------------
null [from org.csstudio.platform.jaasAuthentication]
   <loginModule>
      class = 
org.csstudio.platform.internal.jaasauthentication.JaasLoginModule
      id = org.csstudio.security.jaasAuthentication.jaasLoginModule
      name = JAAS Login Module
   </loginModule>




In your case you should see that at least 2 implementations are loaded,
so pick only one and remove the other plugin from your product.

[Cs-studio-users] Authentification module

[Florian F. <fl...@ep...>]

Dear all,

I'm trying to build a site-specific product of CSS for the PANDA Experiment.
The product contains BOY, databrowser and the BEAST ui-feature.

Like proposed in the doc-book I have created 3 features:
org.csstudio.panda.applications.feature
org.csstudio.panda.core.feature
org.csstudio.panda.eclipse.feature

And the plugin
org.csstudio.panda.product

When I run my product from the IDE, I get the following message:

2012-02-29 17:31:50.904 SEVERE [Thread 1] org.csstudio.auth.internal.usermanagement.LoginContext (getLoginModule) - Found multiple login modules

2012-02-29 17:31:50.919 SEVERE [Thread 1] org.csstudio.auth.internal.usermanagement.LoginContext (getLoginModule) - Found multiple login modules

2012-02-29 17:31:50.919 WARNING [Thread 1] org.csstudio.auth.internal.usermanagement.LoginContext (login) - No login module provided. The system acts as anonymous login


Since the PANDA-Experiment is still in its R&D phase, I wanted to use 
the dummy authorization from SNS.
So I have included these two plugins in my core feature:
org.csstudio.platform.login.dummy
org.csstudio.sns.dummyAuthorization
As far as I know, I have no other authentification modules included.

To be able to set the extension points in my product plugin I have 
listed these two plugins as dependencies. Maybe this causing the error?
Can anyone help me solving this problem?

Best regards,
Florian

You're right, it was no longer accessible.
Should work now.

Hi, Thanks for your quick reply.

I'll try auth & auth, logbook later.

I accessed the link, but it seemed that Reports.tgz did not exits.

Authentication and Authorization is more complicated than it needs to me.
For example, we use JAAS, but it's wrapped a couple more times
instead of using plain JAAS.

For starters, you should build a product that has 'dummy' authentication
and authorization built in.
For that you do need to build your own product,
or you can try the new NSRRC product,
which is basically the "Basic EPICS" product
+ alarm system GUI
+ dummy auth & auth
+ dummy logbook (writes to /tmp/logbook.txt)

To add dummy auth & auth to your own product, see
8_AuthAuth.ppt 
<https://ics-web.sns.ornl.gov/kasemir/CSS/Training/NSRRC/8_AuthAuth.ppt>:


Include plugins in CSS product:
org.csstudio.platform.jaasAuthentication
org.csstudio.platform.jaasAuthentication.ui
org.csstudio.sns.dummyAuthorization



Configure like this in plugin_customization.ini of CSS product:
  # Select 'Dummy' JAAS Authentication
org.csstudio.platform.jaasAuthentication/jaas_config_source=File
org.csstudio.platform.jaasAuthentication/jaas_config_file_entry=Dummy


Now any user and password will work.
You still need to log on, though, but any user name and password will be
accepted.

Yes, these are SNS reports that include some useful archive and alarm
reports,
but also a lot more that is specific to the SNS.
It shows that it is very easy to create a bunch of JSP reports,
but harder to create a setup that is portable to other labs.

You can get a snapshot on
Reports.tgz <https://ics-web.sns.ornl.gov/css/Reports.tgz>

See Readme.txt in there


>3. Table composition of Logbook
>I tried to use Logbook, but there is no information about

CSS includes a plugin that defines the API for making logbook entries.
You will have to implement the glue code to use that with the logbook
that you have at your site.
The org.csstudio.logbook.sns plugin is such a glue code for the SNS
logbook, but you cannot use the SNS logbook at other sites because it
is highly connected to the rest of SNS, for example the system that knows
who is working on what group, responsible for what etc.

You can look at org.csstudio.logbook.olog, a new logbook system developed
by FRIB and BNL. Maybe that is something that you can use at your site.

Otherwise, the NSRRC product contains a very primitive logbook,
just meant to "enable" the logbook functionality in CSS so you can
try it out without a real logbook.

Thanks,
Kay

[Cs-studio-users] Questions about BEAST

[Takashi K. <tak...@gm...>]

Hi,
I'm evaluating the SNS CSS system and I have some questions.
Please somebody help me.

1. Configuring the alarm system
In the document "Control System Studio Guide" says that
using alarm system, the user "alarm_config" can edit the
alarm system configuration and "For initial tests, you can
configure CSS authentication and authorization to use a
'dummy' mode".

http://cs-studio.sourceforge.net/docbook/ch13.html#id422044

But, when I logged in as "alarm_config", I cannot configure
any alarm system configuration. How can I configure the alarm
system?

I also use the LDAP for authentication, but in vain.

2. Web Reports
It seems that there are JSP-based web reports that can make
reports from the RDB storeing alarm configuration and states.
Although I accessed the source repository on SourceForge,
I cannot find the source code. Where can I get them?

3. Table composition of Logbook
I tried to use Logbook, but there is no information about
the teable composition of the RDB.

Regards,
Takashi

[Cs-studio-users] BOY thermometer widget: "Limits from PV" does not work

[Martin K. <ko...@ik...>]

Hi,
the "Limits from PV" function of BOY's thermometer widget does not work
for me. Although caget gives me correct values for HIGH, LOW, HIHI, and
LOLO none of these shows up in the widget. If I disable "Limits from PV"
the static values are used correctly.

Am I missing something or is this a bug?

Cheers

Martin

P.S.: This happens with version 3.0.2 of the NSLSII product.

[Cs-studio-users] BOY: copying slider widget messes up "border width"

[Martin K. <ko...@ik...>]

Hi,
I found a bug in BOY's slider widget: When I copy a slider widget the
"border width" property is not used correctly in edit mode.

Steps to reproduce:
1. Create a slider widget
2. Change the "border width" property to "0" (the slider becomes a bit
bigger)
3. Select the slider and press Ctrl-C
4. Insert a copy of the slider by pressing Ctrl-V

The sliders are displayed differently (see screenshot) in edit mode. In
run mode everything looks as it should.

Cheers

Martin

P.S.: This happens with the current version of the NSLS-II product (64
bit Linux).

Re: [Cs-studio-users] BOY: display widget if $(my_macro) == "foo"

[Martin K. <ko...@ik...>]

Hi Kay, hi Xihui,
> I just added a method widget.getMacroValue(macroName); in the code, so it will be available in next release.
Wow, I didn't expect such a fast reaction. This feature should solve my
problem :-)

Thank you very much!

There's another way to deal with widgets that should appear only under
some conditions. Have a look at jddd (http://jddd.desy.de/ - you can try
it with Java Web Start). It provides a component "if/else" that seems to
be not as powerful as rules/scripts but much more intuitive. What do you
think about this approach?

Cheers

Martin

[Cs-studio-users] BOY: display widget if $(my_macro) == "foo"

[Martin K. <ko...@ik...>]

Hi,
is it possible to configure the visibility of a BOY widget depending on
the value of a macro? I want to use that with a sub-display which
provides a set of widgets. One of these widgets does not make sense if
the macro matches a specific pattern - that's why I want to hide it in
these cases.
Up to now I did not manage to access macro values from rules/scripts.

Any help appreciated

Martin
