Remote support on wan for Gemstone server

Hi,

some time ago i do some test for manage GemTools on remote system with speed up the remote performance of GemTools.

After i see the: tODE - the Object-centric Development Environment by Dale.

Now my question is:

what is the state of the art to manage a Gemstone server remotely ?

What are the prospects for the near future?

Thanks for any considerations,

Dario

Dario,

I'll let Dale comment on tODE. If you have a Windows client, you could try Jade (http://seaside.gemstone.com/jade/Jade.zip) since it has fairly efficient network usage.

Dario,

GemTools is still the goto guy for development ... tODE is not a complete development environment so you still need to have GemTools around to do certain things.

I use tODE to interact exclusively with ss3[1], but it is a production system and I don't do a whole lot of direct development .... minor patches and looking at the object log are very convenient using tODE ...

I have intended to work on tODE more this winter, but I have been sidetracked with an effort to integrate Monticello, Metacello, git and github[2] in particular and Metacello 1.0-bet.32 in general...

-James

i test JADE solution.

On local network it work fine.

From remote session ( by ADSL connection ) i configured the router to redirect the netldi service( 50377) to the specific server where the service run.

When do the Login the jade program answer the :

Network error - text follows:

Noblocking connect ( 87.2...... ....... , port = XXXXX) failed to complete.

Where 87.2...... is the IP address of the server router and the XXXXX is a number of the port ( it change at any Login attempt )

I wrong something ?

Thanks for any consideration.

Re: Remote support on wan for Gemstone server

Dario,

The error report tells us that something failed to connect.

(1) Could you tell us more about your network connection?

(2) What is different between the "local network" (where it works) and the network where it doesn't work?

(3) You have a Stone and NetLDI running on a server with an IP of 87.2...?

(4) Could you send us the result of 'gslist -cvl' on the server?

(5) Are you able to ping the server from the Windows machine? What is the result?

(6) I don't understand the part about configuring the router. Where is the router? Why do you need to configure it?

(7) Are you entering '50377' or 'gs64ldi' in Jade as the NetLDI service?

(8) If you are giving the service name, have you added it to your Windows etc/services file?

Re: Remote support on wan for Gemstone server

Dario,

Another possible issue is a firewall between the client and the server. In order to make the connection from the client (Jade) to the server (GemStone), you need to have access to the NetLDI (typically 50377) and to another port used to access the Gem. This port can be configured when the NetLDI starts, but if it is not configured then a random port will be used.

I suggest that you modify your 'startnetldi' command to add a port option, '-p 50378:50378' and then configure the router to redirect this additional port to the specific server where the service runs. For more details see the System Administration Guide and the following Tech Tip: http://community.gemstone.com/display/GSS64/Netldi+Port+Use.

If Jade was ported to Linux/OSX that would simplify a lot of things here ;-)

Re: Remote support on wan for Gemstone server

I've posted an experimental port of Jade to Mac (OSX) at http://seaside.gemstone.com/jade/. The only issue I found so far is that I need to put the service in as a port number rather than as a name.

Hi James,

I suggest that you modify your 'startnetldi' command to add a port option, '-p 50378:50378' and then configure the router to redirect this additional port to the specific server where the service runs. For more details see the System Administration Guide and the following Tech Tip: http://community.gemstone.com/display/GSS64/Netldi+Port+Use.

i follow your suggest and for now i'm interested to test the port open on the server when i run the startnet script.

In the server i run two Gemstone '2.4.4.1' environment

and one GemStone '3.0.1' environment.

My test is relative to the first Gemstone '2.4.4.1' environment

I change the starnet file to add the port option -p 50377:50379 at startnetldi command.

Now the startnet is :

#!/bin/bash

export GEMSTONE_NRS_ALL='#dir:$GEMSTONE_DATADIR#log:/$GEMSTONE_LOGDIR/%N%P.log'

export GEMSTONE_SYS_CONF=$GEMSTONE_DATADIR/system.conf

export GEMSTONE_EXE_CONF=$GEMSTONE_DATADIR

$GEMSTONE/bin/startnetldi -p 50377:50379 -g -a $USER -n -l $GEMSTONE_LOGDIR/gs64ldi.log

When i run startnet the system open the tcp port but randomly.

The netstat -avntup command for example report

tcp 0 0 0.0.0.0:52479 0.0.0.0:* LISTEN 28526/netldid

If i add the gs64ldi entry to the /etc/services on the server

gs64ldi 50388/tcp

when i run the startnet it open the 50388 port. ( the startnetldi -p parameter aren't considered )

Question:

A) i wrong the startnetldi port option ?

B) if i setup the range to 1 : startnetldi -p 50377:50377

when i do login from GemTools 1-0-beta.8..3 the system erase the error:

'Unable to create a GemStone session.

Netldi ''gs64ldi'' on host ''monviso'' reports the request ''gemnetobject'' failed:

Your netldi request timed out after 60 seconds.

If a gem or page server log file was created for this request it will contain information on why this request failed.

Otherwise check the netldi log ''/opt24/gemstone/log/gs64ldi.log'' for information.'

C) i can work with two gs64ldi service at the same time?

one for Gemstone 2.4

one for Gemstone 3.0.

Thank for any consideration.

Re: Remote support on wan for Gemstone server

Dario,

The startnet script assumes that you have something reasonable defined in /etc/services for 'gs64ldi' (such as 50377). To check for that enter the following at a command shell:

grep gs64ldi /etc/services

My guess is that there is nothing defined, so NetLDI chooses a port at random.

It is quite possible to run multiple versions of GemStone on the same host; we do it all the time when developing and testing. It is, however, important to have one NetLDI for each product version, and to start that NetLDI on a unique "primary" port. If you are running behind a firewall you also need to select a "secondary" port (or port range) for each NetLDI.

You are running three stones, two 2.4.4.1 stones and one 3.0.1 stone, so you need to start two NetLDI processes (one for each version) and you need to select and configure four ports. For purposes of discussion I suggest the following:

2.4.4.1:

primary: 50377

secondary: 50378

3.0.1:

primary: 50379

secondary: 50380

All four ports need to be open on your firewall and properly routed from the client to the server.

When starting NetLDI you need to tell it by command line or environment variables which ports to use. I suggest that you be explicit on the command line.

With $GEMSTONE pointing to the 2.4.4.1 product and $PATH including $GEMSTONE/bin, modify the 2.4.4.1 startnet script as follows:

$GEMSTONE/bin/startnetldi 50377 -p 50378:50378 -g -a $USER -n -l $GEMSTONE_LOGDIR/gs64ldi.log

This tells NetLDI to use 50377 as the primary port and 50378 as the secondary port.

In a different shell with $GEMSTONE pointing to the 3.0.1 product, modify the 3.0.1 startnet script as follows:

$GEMSTONE/bin/startnetldi 50379 -p 50380:50380 -g -a $USER -n -l $GEMSTONE_LOGDIR/gs64ldi.log

This tells the 3.0.1 NetLDI to use 50379 as the primary port and 50380 as the secondary port.

You can replace the primary port number with a service name if you have things properly set in /etc/services (or a network services database), but I suggest that you be explicit to avoid problems.
