Para poder crear un archivo tipo bat o cmd con definirlo de esta manera “file = new asciiio(‘c:\\filex.bat’,'w’);” ya tenemos un fichero llamado filex.bat en c:\ . Ahora bien en nuestro c: o en el del sevidor???? Pues eso solo lo sabremos si el metdodo q hemos ejecutado se lanza del lado del cliente o del lado del servidor, y para salir de dudas mejor definir una metodo static y ponerle server para que de fijo se lance en el servidor donde se este ejecutando nuestro AOS (AX32serv.exe).

static server void Start()
{
asciiio file;
str txt;
;
winapi::deleteFile(‘C:\\file2.txt’);

file = new asciiio(‘c:\\filex.bat’,'w’);

if (file)
{
txt = (strfmt(‘net start “Axapta batch 1″ ‘));
file.write(txt);

file = null;

winapi::shellExecute(‘c:\\filex.bat’);
winapi::deleteFile(‘C:\\filex.txt’);
}

}

Lo cierto es que desde que microsoft cogió por banda nuestro ERP favorito ha hecho buenas mejoras a parte de subirle los costes de instalación y licencia que va muy bien para eso de la facturación mensual. Una de las grandes mejoras es el rendimiento del AOS, originariamente esto del aos era la hiper-mega-solution para grandes redes pero en la practicar era mas rapido una tortuga en java que el dichoso AOS aparte de los miles de errores de sincronización de objetos, formularios y hasta de datos, por que el manejo de la cache de estos era pesimo por no decir pobre. En algunos desarrollos era mejor optar por un diseño plano sobre cliente para evitar sorpresas de ultima hora con las impresoras y dios sabe que mas.

También durante la primera epoca de 3.0 algun iluminati de dangard y luego de navision le dio por dar los cursos de instalación como si esto fuera un IE 7, vamos siguiente — siguiente — etc. Y resulto que muchas por no decir el 60 % de instalación se hicieron sobre dos directorios diferentes de objetos, lo que provoca desde errores en los formularios a errores de sincronía con la base de datos que pueden hacer desaparecer nuestros datos.

Al menos los siguientes sp han corregido muchos errores y han mejorado la velocidad y estabilidad de ususarios.

vaya el siguiente texto de ejemplo de lo que se vendia de un AOS :

 

 

The AOS and the quest for Bandwidth.

When the discussion is about the ‘speed’ of the Axapta system running client and the AOS, some important factors have to be considered. This article will try to explain some of these issues.

Bandwidth, which we all want lots of, is the amount of data that can pass from the source to the destination per unit of time, averaged over many transactions. Measurement in mega bits per second (Mbps)/kilo bits per second (kbps).

Keep in mind that bandwidth is not a measure of speed, but rather of quantity.

If you look at your connection to the AOS as a freeway, bandwidth is a measure of the number of lanes available for traffic. The more lanes you have the greater the number of cars your freeway can handle.

Please keep in mind that bandwidth is not everything. Latency, “the speed”, also matters.

Latency, is the time it takes for a single data transaction to occur — the time between sending the data on the source end and its reception on the far end. Measurement is in millisecond, ‘ms’.

The speed on your freeway would be measured in the speed the cars traveled, and would be independent of the number of lanes available, (bandwidth). Speed on the network/Internet is determined by a measurement called “latency.”

Simply put, latency measures the minimum amount of time possible for a packet to be transferred over your connection. The higher the latency gets the longer transfers take and the lower your connection “Speed Limit” will be.

This means that there will always be a minimum time that you can never beat. This is the latency. Even if you send a very small packet, the fastest it can get to the server will be depending on the latency and not the bandwidth. (This of course, if you have enough bandwidth for the packet)

So the perception of speed, is (therefore) actually a combination of these two performance numbers.

The ping command can inform you about the latency on the network from your client to the AOS in ms.
A more accurate way is to use the build in performance measurement tool in Axapta 2.5. e.g. (Administrator;Inquiries;Performance Tests;Performance Tests;Client/Server connection.) If the network has a high load of traffic, there is a possibility that the lower prioritized icmp packet will indicate higher latency then there really is on the network.
This is due to the fact that the icmp packet used in combination with the ping command has a lower status on the network than the TCP packet.

What about the ASU?

Navision a/s has defined the following:

1 ASU is the load generated by Axapta 2.5 when creating and invoicing the amount of 10 salesorder with each 5 orderlines processed over the period of 1 hour.
That’s a total of 10 Salesorder with a total of 50 salesline in one hour.

Please read at Technet.damgaard.com ‘ResourcesHardware Sizing Guide’ about the definition of ASU. Please also read about the number of ASU the different Axapta modules produce.

How does all the above relate to the AOS?

With the above definition of ASU and demand for bandwidth and latency, and not at all having discussed the need for hardware, Navision a/s on the standard Axapta 2.5 gives the following rule of thumb that:

1 ISDN 64kbps is able to handle the throughput of 10 ASU, meaning that you e.g. can produce 100 salesorder with a total of 500 saleslines over a period on 1 hour.

The demand for latency has to be <100ms and preferably <50ms on the communication line.
When the latency is high, it has a huge impact on the speed of the system.

Development gives the following formula to compute the bandwidth requirements.

The formula

ASU x 6,4 kbps = y
If y < 64 kbps then bandwidth = 64 kbps
else bandwidth = y kbps

E.g. The requirement for bandwidth by the load of 20 ASU
20 x 6,4 kbps = 128 kbps
Required bandwidth = 128 kbps

Keep in mind that the above has been tested on a standard Axapta 2.5 installation. If you have been adding to the standard application you have to consider the impact of this.

Recommendations

These can be rule of thumb only so please apply your common sense when sizing for a customer.

When talking bandwidth and latency requirements, you will need to agree to a performance level for Axapta with your customer.

Make sure that the bandwidth and latency are measured using Axapta’s built-in tool rather than relying on what the network provider promises and measure it periodically over a period of time and particularly at peak hours to ensure that you know what the user will experience. Also make sure that the measurements are done on the production environment with as realistic a load as possible. It is of little value to measure one client loading a line that has to provide for 100.

Preferably Axapta should have a dedicated line to avoid mail, print etc. generating inexplicable sporadic bad performance. If this is not possible, make sure that the connection amply sized.

Bear in mind that due to the client/server architecture of Axapta, Axapta is hit very hard from high latency.

What about the future?

In the future Navision a/s have plans to produce some more detailed information in regard to the AOS communication and different types of communications lines.

The concept of Axapta System Tables

Axapta system tables contain data that the Axapta kernel uses to control the behaviour of the kernel.  Axapta system tables are created automatically by the kernel, when Axapta is started for the first time against an empty database or after a service pack upgrade.

Axapta system tables are in many ways treated as ordinary Axapta tables from the kernel’s point of view. They are synchronized in same way and inserts / updates of the tables are done in a similar way.

System tables are not company specific and do not have a “DataAreaId” column.  Therefore, system tables are implicitly treated as if they belong to the “DAT” company.

All system tables (except “SqlSystemVariables”) have a “RecId” column, which is updated as an ordinary table belonging to the “DAT” company.

Some system tables has the following standard columns:

·         MODIFIEDDATE

·         MODIFIEDTIME  

·         MODIFIEDBY    

·         CREATEDDATE   

·         CREATEDTIME   

·         CREATEDBY

 

All system tables (except “SqlSystemVariables”) have a TableId.  The TableId’s for system tables starts at 65508 and each field in a system table also has a Id that follows the normal rules for Id generation of FieldId’s.  Please refer to the form “SysSqlDictionary” to see the mapping of system tables and TableId / FieldId.

Axapta system tables can’t be accessed or viewed directly from the AOT (Axapta Object Tree).  Furthermore, you should not access the system tables Axapta application layer.

This document contains a description of the most important Axapta system tables, except the table “SqlSystemVariables” which is described in another document. The information in this document is not valid for the table “SqlSystemVariables”.

 

Description of Axapta System Tables

ACCESSRIGHTSLIST (TableId = 65526)

This table contains info about explicit granted access rights for the defined user groups.

Note: Until you have explicitly defined permissions for a table, access to tables is defined using Feature keys. Once you set restrictions on a particular table for a particular user group, all other groups automatically have No Access to that table. As this will seriously impact the way the system works, you are presented with a warning dialogue before any change takes effect. In the dialogue you must decide whether other user groups should have no access as the result of the change you are making, or if other groups should keep their present permissions.

Buenas, pues todo el mundo sabe lo que es un cluster de maquinas no??,  el que no se pede pasar por la wiki y luego seguimos.

Total  Ax (axapta 3.0) permite instalar un balanceador de conexiones entre dos o mas AOS, para que sirve esto, pues más bien para no mucho, el concepto es que el dependiendo del número de usuario que se han conectado a un u otro AOS este cluster distribuye la conexión entrante para mantener un numero homogéneo de conexiones. 

Nada de  transacciones o de carga de procesos, simple y “molt macu” para vender un poco de tecno-logia al puro estilo de las modas de internet. Seguro que en un par de meses se les ocurre algo para dual core.. jajjajaa..

Para terminar un copy paste de como se instala y se configura.. Perdon por los derechos de autor.. jejjeje

Axapta Object Server cluster

The Axapta Object Server cluster environment is build to provide load balancing and fall back. An Axapta Object Server can be specified to belong to a specific cluster. If the same cluster name is given for a number of object servers they all belong to the same cluster. A user can be specified to connect to a given cluster.

Suppose a number of servers are set up in the same cluster – named AOSC. They should all use the same application and database, and in other aspects have the same settings. All clients connecting to the AOSC should be specified to search for servers belonging to this cluster, otherwise the load balancing mechanism will not work properly. A client starting up against an Axapta Object Server Cluster will start out by broadcasting an UDP package requesting Axapta Object Servers fulfilling names and IP server masks given in the client settings to respond. It is therefore vital that firewalls allows such packages to pass through. The client will receive answers from all Object Servers with information on object server name and the name of the instance plus the number of clients connected to that instance. The client disregard information from servers not belonging to the requested cluster. The client then chooses one of the instances with the lowest number of clients.

Since a client automatically can choose from all servers in a cluster one or more Object Servers can be down with out changing the connection procedures. However performance might suffer severely due to higher load on the fewer servers.

Setting up the server

On the server manager select the server of interest and click settings. In the advanced field write -cluster=<my cluster name>. The cluster name can be up to 10 characters long.

Setting up the client

In the configuration tool choose the configuration of interest. In the advanced field write -cluster=<my cluster name>. The client setting for connecting to an object server depends on two situations. The first situation being both client and Axapta Object Servers being in the same subnet. The second being client and Axapta Object Servers belong to different subnets.

Recall the settings in the configuration utility for connecting to an object server:

- Axapta Object Server Mask
- Axapta Object Server host names
- Axapta Object Server IP Address masks

When the client and Object Servers belong to the same subnet the above three masks can be left blank.

When the client and Object Servers belong to different subnets the IP Address masks should contain the mask for the subnet the Object Servers belong to. An example could be 192.88.253.255, where the last 255 specifies that the search is done among servers in the subnet 192.88.253.*.

Note – if client at any time receives only service response from Object Servers within the same cluster it will automatically choose the least loaded of these servers without having to specify the cluster name in the client configuration. This means that if your installation is one single Axapta cluster, there is no need to change the existing configuration with respect to cluster name. Ensure that all relevant Object Servers are located by client configurations network set up.
