ShellInABox + Harbour Technologies - A Working Model

[Pritpal Bedi]

Hello Everybody

Below is the link and usernames/password to have a 

demonstration of what Harbour can achieve, and how fluently,

and can keep pace with modern technologies.

This implementation consumes following components:

EXTERNAL

ShellInABox

HARBOUR

GTNET  -  Request  Przemek to make available this fantastic library as a Commercial Distribution 

HBNETIO - For certain parts of wider implementation - Thanks Przemek

HBHTTPD - For REST compliant, highly validation oriented, re-routing engine (tuned for my purposes) - Thanks Mindagaus

DBFCDX - Our beloved database driver - Thanks Przemek and all others who contributed

HBHARUPDF - Using enhanced version of PDFClass() - Thanks Jose M.C. Quintas 

COMPILER

GCC

OS

Ubuntu 14.04 LTS - AMI - Amazon Machine Image

INFRASTRUCTURE

AWS - EC2.: SSL Offloading is materialized on the load-balancer.

LINK TO DEMO APPLICATION 

https://erp.vouch.in

USERNAMES

VouchUser1, VouchUser2, VouchUser3, VouchUser4, VouchUser5, VouchUser6, VouchUser7, VouchUser8, VouchUser9, VouchUser10

PASSWORDS

u01, u02, u03, u04, u05, u06, u07, u08, u09, u10

ACTIONS FROM PROGRAMMERS POINT OF VIEW - PROVIDING REPORTS VIA HTTPS

Trading > Sales > F3.Brow > F4.Prnt > Click on the https link in the alert  > Reports PDF will open in the browser

Accounts > Vouchers (S) > F3.Brow > F9.Stat > And look at the time it took to scroll browser for 5100+ records.

The similar operation on desktop application takes thrice this time - the powerful DBFCDX.

This Software-As-A-Service architecture is about to be rolled-out for Indian businesses in the near future.

The architect is highly distributed, scalable, and fault tolerant. This implementation also exposes 

Windows desktop client and Android mobile client with different usages. But for sure browser based 

interface is expected to gain major importance.

Very good.

Hi Pritpal

thanks for your example

a simple question

how many concurrent user can work at the same time, 10, 100, 1000, 10000, 100000 ?

Hi

 

thanks for your example

a simple question

how many concurrent user can work at the same time, 10, 100, 1000, 10000, 100000 ?

Depends upon the infrastructure capacity.

I have tested on EC2-Nano ( 500mb of ram ) fraction of a core cpu,

and could connect 40 users concurrently without issues. Provide the 

server of many cores and memory and you can run as much instances 

as possible. From applications point of view there are no limitations.

Also I told that this is a distributed system.  Means, one server will hold 

accounts as many users as can it hold. For example, if I attract 20 accounts 

of 2 users each, I can host all of them on one T2-Nano. 41st user, or 21st 

business account will go on another server. In case I attract an account with,

say 100 users, then I will host them on a better server, may be t2-small

or better to ensure that all 100 users are capable of logging simultaneously.

Connected users are entirely based on the the underlying hardware 

infrastructure. More cpu power, more the concurrent users.

From DBFCDX point of view I have not faced any issues no matter 

how many users are logged-in together. Even in case of NETIO the 

connectivity has never been a restriction.

BTW, if I have not missed, what you mean by concurrent users ?

Concurrent users logged for one account ?

Concurrent users logged on one server ?

Concurrent users accessing one table ?

I tried to explain all above scenarios but in descriptive manner.

If you have specific, let me know, will try to answer per best of my knowledge.

Master, congratulations. It was very good.

Could it be that in the future, it would be possible to run graphical screens like (Hwgui) in a scenario like this?

No.

This is a pure console implementation - GTNET + GTTRM.

[Leonardo Machado]

ok, tks

Hi Pritpal

What does gtnet exactly do in this chain ?

How you limit your console session to only one app and id session ?

Hi Angel

 

What does gtnet exactly do in this chain ?

Though Przemek can provide a detailed insight into the subject, I try to explain 

from a user's point-of-view. GTNET is a 3-component implementation.

GTNET Client 

GTNET Server

GTNET Application

Client connects to Server which spawns Application and Client-Application 

communication is established. 

 

How you limit your console session to only one app and id session ?

No need of any session management. It is a direct TCP implementation. A connected architecture.

[Angel Pais]

Very Interesting !

Hi Pritpal

thank for your replay

may question is techincal , how many concurrent users simultaneously logged and working on a server ?.

but now some questions

where we can download GTNET ?

a mini HOWTO for use it can be possible ?

regards

Domenico

[Francesco Perillo]

GTNET is not public.

More than 2 years ago Przemek explained what GTNET is.

[Pritpal Bedi]

Hi

may question is techincal , how many concurrent users simultaneously logged and working on a server ?.

This is exactly what  I had explained. Again, 

The concurrent connectivity per server is dependant 

on the the hardware capacity. CPU, cores, memory and bandwidth

are the deciding factor. For example on a AWS-EC2:t2-nano 

( 500 mb - 10% of a core ) I am able to connect 44 clients.

On a T2-Large I can connect 200 clients. Provide it more 

powerful server for more connections. 

Harbour and GTNET do not impose any restrictions on number of users.

 

where we can download GTNET ?

This has to be requested to Przemek, as I had announced in original post.

 GTNET is scheduled to be released commercially but when, is not known to 

the community.

a mini HOWTO for use it can be possible ?

I am not authorized to shed any details. Wait until Przemek makes up his mind to this effect.

Hi Kamlesh

SatSiriAkal.

Thanks for using my native salutation.

I am create New User and User create success but not found client key and user and password.

This is a demo version. You have to use one of the username and corresponding password

which I have provided. Creating a new user involves some parameters which are available 

only when someone request for a commercial license. Demo Vouch is made available 

to Harboureans is to showcase the power of Harbour and undisputed capabilities of Przemek.

I have setup other endpoints which do not show-up Create, Delete options:

And some more but above are enough for all of you to play with.

You will not be asked to enter username / password by clicking on above links.

You are free to add/edit/delete and all other actions the software implements.
