Re: [ptp-dev] More PTP Milestone1A problems
Sorry for the confusion! Maybe Chris could help out with getting dstore working for RDT? I don't have a lot of experience with it.

The requirement for ssh-only connections for proxies is fine with me and satisfies any requirements for my testing of proxies for PTP 2.1. I might 
have been confused about what you were asking me, where I thought you
wanted me to try to set up a dstore connection between my windows and
AIX/Linux systems. That was what I was trying to do, and am having
problems with getting that to work at all, even with using the remote
c/c++ development view. The dstore problem isn't keeping me from getting 
anything done, so we can look at that at your convenience.

Re: [ptp-dev] More PTP Milestone1A problems






Ah, good!

You may have missed one of my previous emails. Currently, PTP resource
managers only work over ssh connections. You can use dstore
connections for the Remote Development Tools (RDT), but you will have
to create a separate connection for the resource manager. If you use
the PTP new RM wizard, it will only create an RSE ssh connection.

It's best to think of PTP and RDT as completely separate for now, even
though we plan to merge them together in the future.

Hope this makes sense.

I tried three connections from my Windows system to my Linux pSeries
system, a 'Unix' connection using dstore, a 'Linux' connection using
dstore, and a 'Linux' connection using ssh. I have the remote c/c++
development perspective open, and am creating the connection by right
clicking in the remote systems view, clicking new connection and going 
thru the wizards. I'm accepting whatever defaults there are on each
page
other than selecting dstore/ssh as the connection type. After the
connection is created, I try opening shell processes/my processes.
Only
the ssh connection works. Both dstore connections hang. I started the
dstore server on the linux node (as root) by invoking daemon.pl
without
any arguments. The daemon starts by listening on port 4075. When I
click
'my processes', I see messages from the daemon that a new server is
launched on port nnnnn but nothing more happens. If I shut down
Eclipse
and restart it, I get a message from the daemon 'Finished on port
nnnnn'.

Re: [ptp-dev] More PTP Milestone1A problems






Dave,

I think there are two potential causes here. One is that you're
running PTP under Windows, the other that you're trying to connect to
an AIX box. Can you try connecting to a Linux box rather than AIX
first?

The RSE connection itself was working. It was only when I tried to
start
the proxy that I had a problem where 'start proxy' would hang until I

the RM and clicking the browse button.

I'm not having any luck setting up a remote tools connection. I'm
still
seeing hangs when I go thru the RM create wizard where Eclipse is
trying
to establish a connectiion. If I click the cancel button in the

popup, the cancel button grays out but Eclipse is hung and I have to

the RSE 3.0 downloads) that I'm running on my AIX system, invoked as
root
by running 'daemon.pl')

I reinstalled my Ganymede Eclipse clean, reinstalling the PTP 2.1 M2
build, the CDT 5.0.1 build dated 9/5, and RSE 3.0 runtime. I then
checked
out all the PTP code from CVS HEAD then tried to run a 2nd eclipse
session. I try to open the PTP runtime perspective perspective in
that
second session and get a popup 'Problems opening perspective

Dave,

Can you also verify that the RSE connection is working by editing
the RM
and clicking on the "Browse" button?

Could you try with a Remote Tools connection instead of an RSE

Do you see the same problem?

I just verified that I don't have the manual launch checkbox
checked. I
had the same problem. I tried clicking the manual launch checkbox to
see
what would happen. That also required  me to start the proxy
manually, as
I expected.

I had my RSE connection set up without a stored password. If I had
the
manual launch checkbox unchecked, then when I tried to start the
proxy I
would get a password prompt that I responded to. If the manual launch 
checkbox checked, I would not see the password prompt. In both
cases, the
proxy had to be started manually.

I now have a stored password in my RSE connection and now when the
manual
launch checkbox is unchecked, I don't see the password prompt, but I
still
have to start the proxy manually.

Thanks for finding that bug. Working on a fix now. I know this is a
silly

you?

is returning null. It seems taht the constructor for

I'm not sure that's the right way to fix it, but it seems to me it
should
work for this specific case since the proxy is invoked by absolute
path.
I get past the null pointer exception and that particular hang. I
end up
still hung a little later though I get the following output in the
console

At that point, proxy startup is hung. I don't see any sign that my

and run
that on my remote system, then the proxy startup completes and I
have a
running proxy. At that point, I can run a PE job and everything works 
normally.

Re: [ptp-dev] More PTP Milestone1A problems










Sorry for the confusion. I'll update the release notes as soon as I
get a chance.

It's best to consider PTP and RDT as completely separate for the
moment. If you're using RSE, then you'll need an ssh-only connection
for PTP and a dstore connection for RDT. We're going to need to work
out how to make this more transparent in the future, but for now you
can either create both connections using the RSE connection manager,
or use the PTP RM wizard to create the ssh one.

Will the proxy startup work with a ssh-only rse connection or is
dstore
required for that too? I was able to start bthe proxy with a ssh rse 
connection in PTP 2.0 a while ago, don't know if anything is
changed.

[ptp-dev] More PTP Milestone1A problems






I tried the PTP milestone1 build again tonight and got a little
farther
with trying to create a new remote project. This time when I tried
to use
the new remote project wizard, I was able to choose the remote tools 
filesystem and click the browse button next to the location text
field on
the first wizard page. This time, I was able to select a connection
name
from the dropdown at the top of the browse directory dialog, and
then
browse my home directory on my remote Linux system and select a
directory
on hat system. However, as I tried to advance thru the wizard pages
I got
a message in the PDE error log window that the directory path I
selected
could not be opened, and the finish button for the wizard never was
enabled. The odd thing was that the pathname that showed up in the
error
message had '\' as directory delimiters instead of '/'. My eclipse
GUI is
running on a windows XP system so I'm wondering if pathnames are
being
sent to the Linux system with '\' in the path name.

I wasn't sure why this was failing so I downloaded the M1A build.
Now when
I select browse in the new remote project wizard and then click a
connection name in the browse directory dropdown, I get a progress
dialog
but it freezes at about the halfway point and the connection doesn't 
complete within a couple minutes. At that point I canceled the
progress
dialog.

Another problem that I have been seeing, and which still happens in
the
M1A build is that if I have a PE proxy running when I shut down
eclipse,
then the next time I start Eclipse, where I have a different IP
address
(because I've dropped my VPN connection and then reconnected), then
when
PTP tries to restart the proxy, it fails and the icon for that proxy 
is
blue. At that point, I can't do anything with the proxy. I shot down 
Eclipse and start again, and the proxy icon is now gray (inactive).
If I
fix the local address for proxy connection in the resource manager
wizard
so it matches my current IP address, I can start the proxy and
everything
is fine. If there was a way to reset the state of the proxy icons in 
the
resource manager wizard so that it wasn't blue, I wouldn't have to
restart
Eclipse to fix the problem.

I have what I think is a working RSE connection. If I open the
Remote
System Explorer perspective and open Sftp files or shell processes
in the
tree in the remote systems view, I can see files and processes
appear in
the view. I switched to the PTP runtime view and tried to create a
resource manager using the same RSE connection. The first problem is 
that
if I change the remote service provider to RSE, then the browse
button
next to the proxy path edit filed does't do anything. If I select
local as
the remote service provider, then I get a file selector dialog. I
switched
remote service provider back to RSE and pasted in the full path name 
to my
proxy and filled in the other fields in the wizard and clicked
finish.
Then I tried to start the proxy. I get a progress dialog for a
couple
seconds and then I get a popup dialog with a message 'Failed to
start
resource manager' and the proxy icon goes to the blue state.
