Hi Team,

I am trying to install Schedulix 2.8 in linux box(RHEL 7.4) with postgres
My doubts could be silly also. Please excuse and clarify me.
 
1) What is the use of Schedulix server and client? Why because, I am installing Schedulix in a singe Linux box. So i think only server installation is sufficient. Is my understanding right?

2) While using the command 'server-start', below error is thrown.
[schedulix]/home/schedulix/schedulix/bin> server-start
/home/schedulix/schedulix/lib/functions.sh: line 46: syntax error near unexpected token `('
/home/schedulix/schedulix/lib/functions.sh: line 46: `which()'
Attaching function.sh file for reference. I couldn't see any discrepencies in the file.

3) What are the values to be configured in .sdmshrc file. In the sample file, below inputs are provided.
$ cat ~/.sdmshrc User=SYSTEM Password=G0H0ME Host=localhost Port=2506 Timeout=0 ( what are these parameters -user, password, host and port?)

4) While executing following commands, getting Connection refused error.
[schedulix]/home/schedulix> sdmsh < /home/schedulix/schedulix/install/convenience.sdms
Connect Error: java.net.ConnectException: Connection refused (Connection refused)

[schedulix]/home/schedulix/schedulix/install> ./setup_example_jobservers.sh
Connect Error: java.net.ConnectException: Connection refused (Connection refused)

Thanks in advance.
Regards,
VETRI

Hi Vetri,

there are a couple of scedulix rpms:

1. schedulix-base
    This package contains the common files for most other packages
2. schedulix-server-pg / schedulix-server-mariadb
    This, together with the schedulix-base package sets up the central scheduling server.
    That's the server in the centre of the architecture schema as shown in http://www.schedulix.org/en/highlights/architektur
3. schedulix-client
    This package is required to set up jobservers/agents
4. schedulix-zope
    This package sets up the Zope server for the Web GUI

The doc package provides the documentation, the example package provides some examples.

In your case you'll need all packages described above. The doc and examples are optional.

----

Is it possible that your /bin/sh points to something else than /bin/bash?
The sdmsctl script ($BICSUITEHOME/bin/sdmsctl) calls /bin/sh as a command interpreter, and depending on the Bourne shell you use, this works or fails.
Please change the hashbang line into

#!/bin/bash

and try again.

----

The .sdmshrc file makes it easier to work with the sdmsh command, especially in a scripting environment.
For a direct connection to the scheduling server, you need of course the host where it runs, the port at which it listens, then you need the user name and the corresponding password for authentication.
It is possible to specify the values at the command line of sdmsh, but that would mean your password is visible to others if they just do a "ps -ef".
If the password isn't specified, the utility will ask for it, but that makes it hard to use within a script.
The .sdmshrc file provides all the required information, no passwords on the command line, no interactive action.
Needless to say that the file permissions should be 0600

----

Since you had issues with the start of the scheduling server, it probably didn't start at all.
This means that no process is listening at the 2506 port.
Hence the "connection refused".

HTH

Best regards,

Ronald

Hi Ronald,
Thanks for the elaborate response. That gives me little more clarity. 
Now I am trying to install zope server using rpm package. Getting dependency error as below.

I tried downloading AccessControl package separately and kept in user home path. But while running rpm command, it doesn't pick up the package as it is not able to recongnize it.
Kindly guide to overcome this installation error.

Hi Vetri,

since the installation already fails at the first python module it wants to install ("from -r ... (line 1)"), it could be a problem with your Internet connection or you could have a firewall issue.
Or maybe pip chooses a wrong mirror for downloading. Hard to say.

If your Internet connection is OK, you're probably running into one of those weird python/pip related errors.
From my experience those are transient and a repeated "yum install" (you might have to remove the package first) often works.

If your box isn't connected to the Internet, or if you have some firewall issues that are beyond your control, you'll need an "offline" installation.
In that case I'll post a kind of recipe.
My first action in your situation would be to give it another try first. If the problem persists, I'll guide you through the offline installation.

Best regards,

Ronald

Hi Ronald,

I tried repeatedly for installing. Didn't work out. 
Also I do not have internet access on my Linux server. Kindly guide on offline installation.

Hi Vetri,

well, without an Internet connection the Zope installation won't work out of the box.
The process tries to download about 50 Python packages, which is proved to be hard without a connection.

The basic idea is:

1. download the packages yourself
2. setup the Zope server manually
3. install the schedulix-zope package _without_ executing the pre- and post-scrips

I've uploaded a document that describes this procedure more in detail: https://www.independit.de/Downloads/schedulix-setup.pdf
Please note: it is only a draft, basically formatted notes I took while performing an offline installation myself.

Hope it helps. Don't hesitate to suggest improvements of the document.

Best regards,

Ronald

Hi Ronald,
I have enabled internet in my server now. I also tried the connection by wget( eg: wget  https://www.google.com). It  works.

I tried zope server installation command now.

Once again, it shows the same error. I am downloading the packages as mentioned in '/opt/schedulix/schedulix/etc/zope_requirements-2.13.26.txt' file.
Do let me know, if the above error can be fixed so that the manual action will be avoided.

Hi,

seems your internet connection is not open enough for pip to download packages.
First try to install any python package using pip.
Fix any problems with internet connections, filewalls, ... and try to continue installation after pip is working.

Regards
Dieter

Hi Dieter,

Yes you are right. I am not able to install pip itself. getting similar error.

Hi Dieter,

Apologies for the delayed reply.
The error was due to "Internet connection" only . It was not opened correctly in firewall.
Once the connection was fine, I was able to proceed with installation of Schedulix.

VETRI
