Ouch - that may be quite a big deal for us.

I guess we will recreate the problem before attempting to solve.

.. but it doesn't work reliably on Linux for us.

With the  --launcher.openFile option, the launcher tries to locate an already running instance.
If found, it asks that instance to open the file. Otherwise it starts a new instance of CSS.

How the already running instance is located depends on the operating system, but basically it looks for a window with matching name, and then sends a message to that window, for example an X11 message on Linux.
That's also why the product name must be set correctly, see http://cs-studio.sourceforge.net/docbook/ch29.html

On our Linux setups, it works for a little while. But once CSS has been running for longer, the launcher will no longer find the already running instance.

OK, so:

cs-studio --launcher.openFile "<path to file> macro1=value1,macro2=value2"

Thanks!

Hello all,

It's possible to open a file in CS Studio from the command line using --launcher.openFile

Is it possible to pass macros when doing this?

Dear Martin,

Thanks for the information and avices.
Indeed my idea was to store the sort-time data in a table/DB that  I 
could just simple drop or remove.

But as far as I understood, it is possible to configure the same channel

same twice in the configuration file for an engine, but I don't see what 
forbid it Archive Engines are running in different machines.

Obviously we are doing something wrong here. I guess our IOC servers are

My idea of the short-term database, was something like this:
Store as much as possible data in case  something breaks. If something 
breaks you can do the post-morten analysis. If everything is fine delete 
the data daily (or every two days).

Hi Zunbeltz,
> Do you take some care on not trying to write at the same time with
> different engines? Or some ohter measure?
You don't need to do that. The DBMS takes care of that. You simply write
values with a channel name and a timestamp into the table. When you
retrieve data you get everything that matches your request (e.g. a
certain channel name and within a certain time span).

>> In principle, the channel configuration contains a "retention"
>> parameter. You could configure that to for example set the
>> retention of some channels to "1 year", and then you can write a

Be aware thought, that deleting data usually does not free up disk space 
with most RDBMS. You also need to run VACUUM which can take a long time. 
That's why some labs use different RDBMS archivers, e.g.

Archiver 1. Stores the full data (e.g. 10 Hz), keeps data for 1 week, 
uses fast SSDs
Archiver 2. Reduces data to 1 sample per minute, keeps data forever, 
uses slow hard drives

If you partition your database over time (1 partition per week) you can 
simply keep two tables (in other words: DROP one table every week - 
which is very fast). Partitioning can also speed up data retrieval a 
bit. See [1] for details.

>> The SLAC Archive appliance has the idea of
>> short-term/middle-term/long-term
Since the (SLAC) Archiver Appliance is not using a RDBMS for data 
storage (only for meta data) it can handle this in a different way: It 
saves data to short-term storage (usually a RAM disk) first. After a 
certain time it moves the files to mid-term storage (usually local disk) 
and after an even longer time it moves the data to long-term storage 
(usually NFS). This ETL process does not reduce the amount of data _by 
default_ but I think you _can_ configure filters [2] that reduce the 
amount of data along with the ETL process.

HTH,

Martin

[Cs-studio-users] Bug using keyboard in confirmation dialog and how to solve utf8 char problems

[Benoit <ben...@gm...>]

Dear all,

I am using CSS/BOY 3.2.16 and I have found a small bug with confirmation
dialog and keyboard:


   - I have used a Boolean Button with Confirmation Dialgog when Pushing
   - This button is connected to a PV called $(user):CtrlRstCmd that when
   we write 1 inside it reset some part of our HW and go back to zero
   automatically.
   - If I press the button a confirmation dialog is open
      - If I use the mouse to click Cancel, No or Yes everything is working
      well
      - If I use the keyboard to select: Cancel, No or Yes, the mouse stay
      in "pressed mode" (icon of finger in my PC) and when I click again the
      confirmation dialog re-appears.
      - This action can be done in loop until the mouse enter in another
      clickable widget.


Then I have another question, In my EPICS database I have some characters
(degree symbol: º) saved in UTF-8 format.
This character can be read correctly using CSS/BOY under Ubuntu  but not
with CentOS. How could I solve this problem, do I have a way to force
charset to UTF-8.

Cheers,

Do you take some care on not trying to write at the same time with 
different engines? Or some ohter measure?

In our installation we have just 290 PVs (4 of them are 2500 arrays). 
Most of the PV are sotred on change (this means that ACCT noise data is 
stored at the moment). This amounts to ~7 GB of data per day. I can 
image that at SNS you have a much bigger data. What do you cope with that?

Re: [Cs-studio-users] Multiple ArchiveEngines

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

Hi:

We run about 40 archive engines. One for channels related to vacuum, one for water, one for low-level RF, …
All write to the same RDB, so that's not a problem.

There is no short-term/middle-term/long-term, though. All go to the same RDB tables.

In principle, the channel configuration contains a "retention" parameter.
You could configure that to for example set the retention of some channels to "1 year", and then you can write a tool that deletes data for those channels that's older than one year.
For now, nobody has written such a tool.

The SLAC Archive appliance has the idea of short-term/middle-term/long-term, you'll have to look for info on that, it's a different system.
As an end user, you can view data from that with the same CSS data browser, but the archive config/engine/storage/maintenance is different.

[Cs-studio-users] Multiple ArchiveEngines

[zunbeltz <zun...@es...>]

Dear all,

As I understand from the CSS documentation; it is possible to have 
multiple ArchiveEngine programs running (even in the same computer) 
different archive prupouses (like short-term, middle-term and long-term 
archiving).  Am I right?

My question is: Is it possible to write to the same DB from different 
ArchiveEngine? Is it dangerous or not a good idea?
My intention is the following. I want to setup a DB for long term 
archiving for the machine physics group. The idea is to store parameters 
with a low frequency, but I also need some how to store more parameter 
when we are running, say a Wire Scanner experiment. For this I was 
thinking to just run another ArchiveEngine that writes to the long term 
DB. Sounds it right?

Thanks in advance,

Zunbeltz

Just to say that I find the nice web browser interface!
Finally, I was able to configure everything and it seems running fine.

Thanks,

Re: [Cs-studio-users] ArchiveEngime configuration with multiple IOC servers

[<zun...@es...>]

Dear Kay,

Thanks for the explanation. I configured the broadcast addresses but it
still seems that the engine is not getting data or that is not writting
anything to our DB.  Is there any easy way to know which to the two is the
problem? (like redirecting to a text file the data)

I attach the conifguration file and the log with the debug detail.

Thanks

They're different.
On a Linux computer, check /sbin/ifconfig. On Windows, check ipconfig.
Look for the IP address, the net mask, and the broadcast address listed in there.

Your IP addresses might be something like 

S1=123.45.10.1
S2=123.45.20.1

If your net masks are 255.255.255.0, their subnets would be

Subnet where S1 resides=123.45.10.0
Subnet where S2 resides=123.45.20.0

and the associated broadcast addresses would be

Broadcast for S1's subnet=123.45.10.255
Broadcast for S2's subnet=123.45.20.255


Why you would use the IP addresses
  export EPICS_CA_ADDR_LIST="123.45.10.1 123.45.20.1"
respectively
  org.csstudio.platform.libs.epics/addr_list=123.45.10.1 123.45.20.1
?

IP addresses will work through most routers, and you get PVs from just those IOCs, in case you have the same PVs on multiple IOCs.
You should not have the same channel name on multiple IOCs in the first place, so that's not a good reason to list individual IOC IP addresses.

So this might look like the easiest way to get going, but broadcast addresses are better in the long run, i.e.
  export EPICS_CA_ADDR_LIST="123.45.10.255 123.45.20.255"
respectively
  org.csstudio.platform.libs.epics/addr_list=123.45.10.255 123.45.20.255

In the real world, you don't have 2 IOCs. You might have 500, and you can't list the IP address of each single IOC.
Even if you only have 5 IOCs. One day you'll add one more. Do you then want to track down every CA client and update its CA address list?
And if you run more than one IOC on the same computer, you MUST use broadcast addresses, because otherwise you will only see the PVs from the IOC that was started _last_, see again https://wiki-ext.aps.anl.gov/epics/index.php/How_to_Configure_Channel_Access
The only downside: You may need to configure the affected routers to pass those broadcasts.

===> In the real world, your clients will eventually either use broadcast addresses, or the single IP address of a CA gateway (and that gateway then uses broadcast addresses).

Thanks for the help Kay,

Sorry for my ignorance in network setups but I have a question.
In the EPICS_CA_ADDR_LIST i have the IP addresses of S1 and S2.
Are addr-broadcast-address-of-subnet1, ... equal to these IPs?

Hi:

You just need to configure the EPICS CA address list settings, see https://wiki-ext.aps.anl.gov/epics/index.php/How_to_Configure_Channel_Access

Note that the command-line caget uses environment variables EPICS_CA_ADDR_LIST, while CSS tools like the archive engine use the preference (http://cs-studio.sourceforge.net/docbook/ch06.html)

[Cs-studio-users] ArchiveEngime configuration with multiple IOC servers

[zunbeltz <zun...@es...>]

Dear all,

In my institute (ESS-Bilbao) we use a modification of ArchiveEmgine that 
writes data to a Hypertable DB (HyperArchiver). In the present setup it 
works great. We have the engine running in the same machine as the IOC 
server.

I would like to run the engine in computer A (C-A) will running IOC 
servers in server1 and server2. C-A is not in the same subnetwork as S1 
and S2 but I can get EPICS variables in the command line with caget.
The problem it seems is that ArchiveEngine is not reading the value of 
the PVs.

My question:

Is there any restriction to the network topology for the ArchiveEngine?

Thanks in advance for the help,

Zunbeltz

Configure it with

[Cs-studio-users] cs studio boy

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

Hey all,

I have two questions concerning CSS:
1st: Is it possible to run an OPI file in a runtime only mode?
        The shifter in the control room should not have the possibility 
to edit/change the OPI files...

2nd: Some widgets in an OPI should only be available for the experts. Is 
it possible to make a widget (e.g. a button or text input)
         in CSS visible only if a certain user is logged in? (How?)

We are still using version 3.1.1

Best regards,
Florian

  1.Can add the property of "show units" to spinner widget in CSS? I think I need to display the unit from PV. 
  2.There are read/write text file and read xml file example in BOY. How can I create a new xml file and write it's element in BOY. I have read some doc about jdom and I had tried to write a program in attach, but it didn't work. Many thanks in advance!

Cheers,

Xuan

Thanks for the warning, we will be making heavy use of the linking container widget so will avoid http. Would it be a good idea for us to look at caching to increase performance?

Interesting, I thought only eclipse project paths could be used in opi links, this is certainly useful to know...

I just found a useful link in the documentation:
http://cs-studio.sourceforge.net/docbook/ch05.html#idp347408

This would appear to be exactly what I need, as it creates projects and links within projects for me. I could then put all the path management in a wrapper script that then calls CS-Studio with a long -share_link argument. My updated diagram would then look like this:

workspace/ # located in user's home directory
  CSS/
  ID1/            # Eclipse project in user's workspace
    motorApp_opi/ # Eclipse link to /dls_sw/.../motor/6-5/motorApp/opi/opi
  ID2/            # Eclipse project in user's workspace
    motorApp_opi/ # Eclipse link to /dls_sw/.../motor/6-7/motorApp/opi/opi

I tried it out, and it created me new projects and links within those projects in an existing workspace, so it seems to do what I want. Have you used this method?

Could I have a copy of this wrapper script please?

After talking to the GDA guys, I think we will start out by creating a default workspace in the home directory of the user (which is NFS mounted on multiple machines), but setting osgi workspace locking = no and see if having multiple instances writing to the same workspace causes us any problems. As we aren't storing much apart from projects full of links at the moment, it might be ok... Have you tried turning off workspace locking?

Thanks,

[Cs-studio-users] Launching CS-Studio BOY screens

[<tom...@di...>]

Hi all,

We're looking at how we should launch CS-Studio BOY screens on beamlines and machine, and have the following requirements:
1) If an IOC has a database template instance from a motor version 6-5, the screens for that IOC should come from motor 6-5.
2) One insertion device may have all its IOCs pointing at motor 6-5, but another may be at 6-4 or 6-2.
3) A user may want to launch sets of screens for many insertion devices at the same time.

The same is true for beamlines, front ends, and other technical areas: a user may start at a high level screen, and drill down to a different version of the motor screen depending which IOC that component is on.

For EDM we simply launched a new EDM for each insertion device with its own search path, but doing the same with CS-Studio would be quite resource hungry. We have had more than 20 instances of EDM running at once, and I wouldn't like to do the same with java virtual machines.

We have come up with a proposal that would work for us:
* Create a project for each insertion device (and beamline etc.) with soft links to the versions of each support module it uses
* Run a command that tells the current running CS-Studio to import that project to the user's workspace and run a screen within it
* We could then have one CS-Studio instance, and let each user have their own workspace, but manage the locations of the projects within it ourselves

The eclipse navigator file structure would look like this:

workspace/ # located in user's home directory
  CSS/
  ID1/     # Eclipse project pointing to /dls_sw/.../ID1/2-0
    motor/ # Soft link in /dls_sw/.../ID1/2-0 pointint to /dls_sw/.../motor/6-5
  ID2/     # Eclipse project pointing to /dls_sw/.../ID2/3-0
    motor/ # Soft link in /dls_sw/.../ID1/3-0 pointint to /dls_sw/.../motor/6-2

Has anyone else done anything similar? How do other sites launch CS-Studio BOY screens?

Thanks,
Tom Cobb
