[Smartfrog-support] scheduler for SF

[Andreas U. <and...@ce...>]

Hello,

we're looking for a scheduler to deploy components on different hosts. 
For a start our requirements are very simple: we have a pool of machines 
where we can deploy components, the scheduler should decide on which 
machine to deploy new components based on very simple criteria (how many 
components are already running on a certain machine ? no cpu, memory 
usage etc. has to be taken into account). Is there already something in 
SF that we could use for a start to experiment with ?

Thanks,
Andreas

Phil,

I've started doing the database and mysql components, the first cuts are 
up in SVN, under core/components/database.

First, generic JDBC operations, which can be bound to hsqldb, mysql or 
whatever, and let you issue a list of commands against a database 
binding you've configured

http://smartfrog.svn.sourceforge.net/viewvc/smartfrog/trunk/core/components/database/src/org/smartfrog/services/database/core/components.sf?view=markup

So far you can issue a transaction; I'd like to get results back in as 
attributes, and I'd like to be able to use operations to test liveness 
of a database.

There is also a ConnectionOpen condition which is successful if a 
connection can be made to a database. this can be used in liveness 
tests, and in components that block until a condition is satisfied (like 
WaitFor). This lets us handle slow starting databases.

There are specific components for hsqldb and for mysql, both of which 
help setting up the jdbc bindings. For mysql I've added an extra 
liveness component that uses the ping() operation on the jdbc driver.

Alongside the jdbc components, I want the components to bring up the 
databases. HSQLDB is trivial, mysql less so. the current (draft) set can 
start mysqld on linux as the current user, with a limited (but 
extensible) set of options:

http://smartfrog.svn.sourceforge.net/viewvc/smartfrog/trunk/core/components/database/src/org/smartfrog/services/database/mysql/daemon.sf?view=markup

One of the fun things here is shutting down mysql cleanly. Our normal 
execution routines shut things down by issuing a destroy() command to 
the process, there being no portable way to issue kill signals to a 
process in Java. I worry what state this will leave the database in. 
I've added a component, mysqladmin-shutdown to issue a shutdown command, 
which can go into a new workflow component, Finally {}, that will run 
the program when it terminates

FinallyTerminateMysql extends Finally {
    action extends mysqladmin-shutdown;
}

I have to test all this stuff, which is a good opportunity for me to do 
more system testing under smartfrog work. Even so, we cannot guarantee 
that the finally action will always run, as systems can terminate in 
interestingly nondeterministic ways.

Do you know how well mysql handles a no-warning kill? While it is busy 
doing some work? I know databases are designed to handle this, but that 
doesn't imply they dont spend a long time recovering when they come back up.

Re: [Smartfrog-support] Web Interface to Smartfrog

[Guijarro, J. <jul...@hp...>]

Hi Omer,

Stever forgot to mention that you can use the Rest interface to SF.

You can find it in SVN core/components/rest:
http://smartfrog.svn.sourceforge.net/viewvc/*checkout*/smartfrog/trunk/c
ore/components/rest/docs/Enabling%20Web%20Based%20SmartFrog%20Management
.pdf

There is not default security build in it. For it, you can configure
Jetty or the servlet engine of your choice to have some access security.
This rest interface offers you total management control of the daemon.

nothing has been written yet, though there is a web service interface to 
provide the same functionality to machines.

1. you can bring up jetty inside the smartfrog JVM using the jetty 
components, then bring up a servlet that lets you browse and view the 
components. That servlet needs implementing...

2, there was a rest component written last summer that may be a starting 
point.

3. if the jmx components were brought up to date with the current JMX 
implementation (or mx4j), then we may be able to use the existing JMX 
web pages.


4. NEC have a tomcat-hosted client for the CDDLM SOAP-based deployment 
API, which can remotely manage a smartfrog system that has deployed the 
CDDLM implementation. A nice little interop demo, but I dont have the 
war file containing their code for reuse, I'm afraid.

[Smartfrog-support] Web Interface to Smartfrog

[Omer K. <Ome...@ce...>]

Hi,

I am wondering is it possible to access Management Control information only
in a read-only mode via a web interface?  Even just the basic information
such as the names of the deployed components would be sufficient for our
needs. How this could be done?

Many thanks,

Omer

Re: [Smartfrog-support] [Smartfrog-developer] How to communicatebetween two differentsmartfrog daemons?

[Guijarro, J. <jul...@hp...>]

Hi Ambika,

=20

Sorry for not answering this message sooner.=20

=20

The best way would be to define a new filter Listener for the Cmd class
and use that to receive all the log coming from the shell. This is not
implemented yet but I could do it for you. I am about to go on holidays
today and back the week of the 8th so it won't be ready before that but
it could be that Kumar or Ritu could help you with it if you need it
before that week.

=20

The other option is to get the log files back to the source with a
component listening to the log or a component that reads the log files
from the remote machine. We use a similar approach with Avalanche and
Ritu and Kumar could show you how to do it.

=20

I am sorry that I cannot help you more but these two weeks before
Christmas have been very busy for all of us.=20

Merry Christmas and Happy New Year.

	What do you need to do exactly? There are many different ways of

Re: [Smartfrog-support] cosmetic change to management console

[Goldsack, P. <pat...@hp...>]

Occasionally you end up with remote references even if it is all local
and so copies of the Component Descriptions are produced - this case is
most irritating but unavoidable. Unfortunately RMI doesn't seem to
provide a way of unwrapping such a reference and obtaining the local
object so contained.=20

Hi,

When you see an entry named "*copy*" in the management console is
because you are referring to an object that has been obtained by the
console as a copy and not a reference. This normally happens when you
are browsing a component description in a remote component. The console
uses that component (its remote interfaces) to get the component
description and therefore, because it is remote, java will serialize the
object and send a copy. When this happens you are not able to
add/modify/remove attributes in the original object because the console
is manipulating a the copy. Also, the console will show you an error
message if you try to manipulate copies.=20

If you want to modify the component description in a remote component
you have two options:

- disable "show CD in tree" and then manipulate the CD using the
language.

- start a management console in the remote jvm. This new console ,
because it is local, will have the right name for the object and you
will be able to make modifications using the tree browser.

[Smartfrog-support] cosmetic change to management console

[Andreas U. <and...@ce...>]

Hello,

looking at the components in sfManagementConsole I always see entries like

D *copy*

Clicking on them gives no Attribute information. Could these entries be 
deleted from the management console display ? This is just a cosmetic 
issue but as we using the management console all the time it would be 
nice to get rid of them.

Best regards,
Andreas

  What do you need to do  exactly? There are many different ways of doing that. In general, any daemon can  locate the other daemons and components and then you can remotely invoke any  remote method on any component.
  
 One way could be using  the EventSend component, for example:

              sendTo:top  LAZY PARENT;

Ah, now that's a really interesting question.

If you look at the javacc parser, it looks like you can have octal 
characters such as \277 , but only three byte ones.

The parser itself feeds input streams (or unicode Reader instances) 
through another generated class, a JavaCharStream which is described as :

/**
  * An implementation of interface CharStream, where the stream is 
assumed to
  * contain only ASCII characters (with java-like unicode escape 
processing).
  */

So
  1. ASCII only
  2. octal characters are allowed
  3. unicode chars are inserted with \u0234 style insertions, very much 
like Java itself.


Because that unicode expansion kicks in before the parser gets to see 
anything, it looks like you can insert unicode in anywhere you like, 
possibly even in the middle of a component name or a reference. They 
work inside values too, though you'd expect something like a double 
quote " to need escaping there.

Once actually deployed, both attribute names and values can be of any 
object type you like, as long as it serializes. In the (prototype) CDL 
XML language, we had full unicode support, using the xml1.0 element 
naming rules to set elements; the values coming from nested text. when 
deployed, all namespaced attributes were published as XML qualified 
names, a (uri, localname) pair that could not be referenced from 
smartfrog at all. That is: the set of names and values you can use as 
attributes is much bigger than the .sf files themselves can handle.


1. If this is not the I18n behaviour you want, let patrick know!

2. we dont have any explicit i18n tests right now. We test on the 
various systems we have to hand, not in any odd locales (turkey, french 
canadian) and so don't catch the surprises they raise. I worry about the 
number of places the code probably has String.equalsIgnoreCase() rather 
than a String.toLower(LOCALE_EN).equals(other.toLower(LOCALE_EN)) 
comparison. We should do an audit for that and fix all occurrences. 
Checkstyle could look for us.

Re: [Smartfrog-support] Bind sfDaemon to a specific interface

[Phillip T. <pth...@jb...>]

Found the offending code in
DefaultRootLocator.setRootProcessCompound().  This problem is caused
by a limitation in the default implementation of
RMIServerSocketFactory.  I found the following link that shows a
possible solution.

http://archives.java.sun.com/cgi-bin/wa?A2=ind0306&L=rmi-users&P=1805

I have some other more pressing matters, but I might try to create a
patch based on this as it would certainly be very useful for my
testing.

Re: [Smartfrog-support] Bind sfDaemon to a specific interface

[Phillip T. <pth...@jb...>]

It seems that no matter what this variable is set to, sfDaemon still
binds to all local interfaces.

$ export SFSERVERHOSTNAME=10.1.5.2
$ sfDaemon
$ netstat --listening | grep 3800
tcp6       0      0 *:3800                  *:*                     LISTEN

Although sfDaemon is still listening on the localhost interface, it
will only accept deployments on the 10.1.5.2 interface.  This looks
like a bug to me.  After a brief look, I wasn't able to find the code
that was doing the actual binding.  Can anyone help?

Re: [Smartfrog-support] Bind sfDaemon to a specific interface

[Guijarro, J. <jul...@hp...>]

Hi Phillip,

You only need to define an environment variable called SFSERVERHOSTNAME.
Ex windows: set SFSERVERHOSTNAME=3Dlocalhost

Alternatively go to bin/setSFDefaultProperties and uncomment and modify
the line where that variable is defined.

[Smartfrog-support] encoding of SF files, allowable characters

[Grove, M. <mik...@hp...>]

smartfrog gurus,
=20
i've just started reading through smartfrog documentation and have been
playing with the latest distribution on sourceforge.  i'm still
recovering from I18N testing that i performed on a previous project, so
you'll understand my initial questions being on that topic.
=20
i couldn't find a discussion in the documentation on the expected
encoding of SF files.  is the file assumed to be UTF-8?  can that
encoding be modified, either globally or on a per file basis?  i'm not
requesting that it be configurable, just want to understand how things
work today.
=20
related to that question is one on allowable characters in SF files.  in
particular, i'm wondering whether there are restrictions on allowable
characters for attribute names and (more importantly) attribute values,
or whether all unicode characters are supported.  i also would be
interested in knowing if there are restrictions on component names,
include paths, codebase paths, etc.
=20
sorry if i missed this in the docs - i'd appreciate a pointer if i did.
=20
thanks.

Re: [Smartfrog-support] which workflow component to use

[Guijarro, J. <jul...@hp...>]

You need a combination of Parallel and Container. There are several ways
of doing this.

1- You use Run to deploy your components and each Run registers the new
components as children of Container:

Container -
 - Run1
 - Run2
 - Run3
 - ...

2- Use the parallel to deploy all children and put a Firebreak as the
top component of any child, in this way if they terminate they won't
take down the parent Parallel.

3- Create a special Parallel-Container. In this case you could add
special code to decide what to do when a child terminates.

[Smartfrog-support] which workflow component to use

[Andreas U. <and...@ce...>]

I see that there are two new Parallel - like components: Container and 
FireBreak. We need the following behaviour:

1. Bring up in parallel components on different sfProcessHost.
2. If on one sfProcessHost a component fails it should not bring down 
all the other components (on other sfProcessHosts)
3. Parallel termination of all components when terminating the parent 
Parallel component.

I think 1. and 3. are implemented in Parallel. For point 2. I'm not 
sure. Would Container be more appropriate ?

Thanks,
Andreas
