AOS Load Balancing

·         Number of client sessions

·         What is a load balancer

·         How connections work when using load balancing

·         Factors when deciding if you need a load balancer

·         Provides fail over ability

·         Balances number of clients between AOS’

·         Control the number of clients per AOS

AOS without clustering

·         With no options marked in the load balancing section each client will connect to the AOS in their client configuration

Each AOS balancing load
As a client connects to an AOS that AOS queries the database to determine which AOS the client will connect to

      AOS as Load Balancer

·         The load balancer makes the connection to the database and determines which AOS the client will connect to

·         This AOS will not accept any client connections nor do any processing

·         This AOS does not count against your AOS licenses

     AOS Load Balancer - Client Configuration

·         In the Dynamics AX 4.0/5.0 Configuration utility you will want to specify the machine name and port number for the AOS load balancer instance

·         Add AOS member instances after the load balancer

      If you do not use a load balancer then you specify all the AOS member instances in your client configuration.  If you do used the load balancer then specify the load balancer first and then the AOS member instances in case your load balancer AOS fails. 

      Database Tuning Tab

·         Max open cursors

·         Max buffer size

·         Allow index hints in queries

o   Batch

   Separate out environments

·         Servers for production environment should be on dedicated boxes

o   Server resources dedicated to production performance

o   Reduce risk of development code utilizing majority of Servers resources

o   Additional components that need .Net BC

   AOS Baselines

·         Performance Monitor

o   Memory

o   CPU

·         Memory usage

o   Different times of day

o   When specific processes run

    Note:

    On Dynamics AX 4 memory limitation of 2 Gig for each AX32serv.exe process

•       If AX32serv.exe consistently around 1.5 gig of memory start evaluating processes and consider adding another AOS

•       If AX32serv.exe reaches 1.8 gig of memory you will likely see user connections to the AOS denied and possibly AOS crashes

   On Dynamics AX 2009 if running on Windows Server 64 bit editions the limitation is based on memory in server.

   Proper code deployment

·         Code promotion schedule

·         Promote code during down time

·         Determine if you will use XPO’s or layers to move code from development/test to production

·         Test code in environment that matches production before deploying   

   Apply Kernel Hotfixes

·         Improved Stability

·         Apply on all machines with a Dynamics AX components

o   Dynamics AX client

o   Enterprise Portal

o   SSRS machine

o   Any machine with .Net Business Connector

Troubleshooting AOS errors

·         Application event log

·         RPC errors

·         Connection issues

·         AOS Crashing

Application event log

·         Windows default event logging tool

·         Different types of events

o   AOS starting

o   User errors

o   Cache flushing

o   Crashes

Events related to connection

·         Lost connection to AOS

·         Cannot or lost connection to SQL

·         Lost connection to the AOS

Connection to AOS

·         Object Server 01: RPC error: Client provided an invalid session ID 75

o   This error message indicates that the AOS has crashed.  After the AOS crashed a client that was open when the crash occurred tried to connect to the AOS.  Since the AOS was restarted it does not recognize the existing client connection.

o   To resolve this issue the client has to be shut down and restarted

• Object Server 01: No ping from 77. Terminating the session.
• This error message indicates that the end user ended the client session before the AOS could return the requested results to the client. 
• To prevent this error message end users shouldn’t end task (ctrl –alt – delete) their Dynamics AX session.  Instead an end user should contact their AX administrator and have them end their session from the online users form.
• Object Server 01: SPID 57 for Session Id 77, is still present in the database. Please delete the SPID from the database.
• This indicates that the end user shut down their Dynamics AX client before SQL  finished processing the request.
• You can delete the SPID or let SQL finish processing
• If you don’t clean up the SPID it could cause issues such as blocking transactions, and open transactions which may lead to transaction log backup failures.

Connection to SQL

·         Object Server 03: Fatal SQL condition during login. Error message: "[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'Corp\axadmin'.“

• This typically indicates the AOS service account does not have permissions to the database.
• Object Server 03: SQL diagnostics: [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'Corp\axadmin'.. Connect information was: Userid = [], Database = [DAX_Prod], Server = [server1], DSN = [], Other = []
• This is caused by insufficient SQL permissions.

·         Object Server 03: Internal Error occurred executing stored procedure when creating session for the AOS.

o   This indicates the AOS Service account does not have adequate permissions to the stored procedures in the database.

Connection to application files

·         Error in file: C:\Program Files \DynamicsAX\ Application\appl\prod \axsys.aod while reading in record 215B1D0
Windows Error: =  Error Code: 64 = The specified network name is no longer available.
Try again?

o   This error indicates the AOS has lost connection to the Application files.

o   To resolve this error message you need to restart the AOS.

Step by Step installation of AX 2009 on Stand Alone System

Step by Step installation of AX 2009 on Stand Alone System/PC/Laptop or on VMs.

Prerequisites are:


Prerequisites Software:

 VMware Work Station or Microsoft Virtual PC 2007.
 Image Burn (To create the ISO files from .exe or .msi files) SetupImgBurn_2.5.7.0
 Virtual Drive(To read the files from ISOs) SetupVirtualCloneDrive5450
 Microsoft Dynamics AX 2009 DVD or ISO
 Microsoft Windows Server 2003 or Microsoft Windows Server 2008 R2 DVD or ISO.
 Microsoft SQL Server 2005 or Microsoft SQL Server 2008 DVD or ISO.
 Microsoft Active Directory (This is with Server 2003 and 2008, runs on command as dcpromo).
 Microsoft Windows XP or Microsoft Windows Vista or Microsoft Windows 7 DVD or ISO.
 Microsoft SharePoint 2007 or 2010 DVD or ISO.
 Microsoft SQL Server Reporting Services and Microsoft SQL Server Analytical Services.
(While installation of SQL, these are the SQL components)
 Microsoft Internet Information Services (Part and package of Server 2003 and 2008).
 Windows SharePoint Services 3.0 Service Pack 1 (SP1) for EP (Enterprise Portal)


Prerequisites Hardware:

 Laptop/Desktop with Microsoft Windows XP or Microsoft Windows Vista or Windows 7.
 Internet Connection (for Online Training and Software or patch download).
 Headphones with microphone.
 Recommend RAM from laptop or PC: More than 3 GB.
 Recommend HDD from laptop or PC: More than 40 GB.
 Recommend Processor from laptop or PC: More than Dual Core (Intel or AMD)


Case One:

I have Laptop, I need to format and I have Windows Server 2003, need to install the AX 2009 over it.

Well in this case first Install the Windows Server 2003. Change the computer/server name to "AX2009" Once you installation is done and you see the computer name is "AX2009", go to run and type dcpromo to create the AD on the same system, since AX 2009 need AD for authentication.

Type domain name as corp.daxadmin.com as FQDN or normal daxadmin.com

If this not support, try to put on your internet connection via dongle. or if you LAN then it would be a great thing just have static IP.

Now once its done with AD for user Administrator  you need to input some complex password like p@ssw0rd.

Now you can enter the laptop or server with domain\user.
In your case it should be corp\administrator or daxadmin\administrator and the password you chose.

Now if all things are well and if you are able to get into the desktop view, now install the SQL 2003 or SQL 2008 R2.

Once done Install the AX 2009 with Microsoft AX 2009 Install documents.

Create user groups in AX 2009

Create user groups in AX 2009

In Microsoft Dynamics AX, permissions and user rights are granted to user groups. By adding a user to a user group, you grant the user all the permissions and user rights assigned to that user group. Before a user can access the product, he or she must be added to the list of product users and added to at least one Microsoft Dynamics AX user group.

By creating users and user groups, you establish who can access Microsoft Dynamics AX and what permissions users have when they are working in the application. Microsoft Dynamics AX requires that all users be listed in Active Directory directory services on your domain controller before they can be enabled on the User form. If a user is not enabled on this form, they cannot access Microsoft Dynamics AX. For more information, see Working with users from Active Directory.

Default

An administrator user and an administrator user group are created the first time Microsoft Dynamics AX is run. The user who opens the first client to connect to an Application Object Server (AOS) instance after installation is set to the Administrator user. The Administrator user is added to the Administrators user group. Administrators have complete access to all forms, menus, tables, reports, the Application Object Tree (AOT), and all security keys.

By default, Microsoft Dynamics AX also creates a Guest user account. The guest user does not have any permissions in the system, and is designed to give access to a public Enterprise Portal site. For detailed information, see Give users access to an Enterprise Portal Internet site in the Enterprise Portal Administration Guide.

Note:

Restrict the number of users who are members of the Administrators user group, which has access to all fields, tables, reports, and modules in Microsoft Dynamics AX by default. If users are made members of the Administrators user group, they can potentially view reports or data that they should not be able to see or change configurations and business logic in the system. Ideally, only those individuals who will configure and administer Microsoft Dynamics AX should be members of the Administrators user group. To further limit this vulnerability, you can create domain administrators, who have administrator rights only to their respective domains. For more information about domain administrators, see Create domain administrators.

Deciding on the structure of your user groups

The groups you create and the permissions you assign to user groups should reflect the structure of your organization. For example, you may want to create groups for Human Resources, Finance, Sales, and Production to name a few, and then set the appropriate permissions for these groups. Create user group names that describe the permissions granted for that group, such as Finance - Full, General ledger - Read Only, Accounts payable - Edit. In this manner you avoid confusion if you have to create additional groups.

Note:

When a user is a member of more than one group and the group permissions overlap (for example, a user is a member of two groups that have access to the General Ledger module), the user inherits the highest permission level between the two groups.

When you are setting permissions for each group, work with business decision makers in each department to determine what permissions each group needs and who should be included in each group.

We recommend that as a security best practice, you create a Developers user group to help minimize the number of users in the Administrators user group. By default, only members of the Administrators user group can make changes in Application Object Tree (AOT), the central repository for classes, tables, and other development elements in Microsoft Dynamics AX. Give the Developers user group access permission to make changes in AOT. Restrict the number of users in the Developers group.

To create a group and add users to that group

The following procedure describes how to add users to a group at the time that the group is created. You do not have to add users to a group when it is created. You can add users to a group later on the User form (see Create new users).

1. From a Microsoft Dynamics AX client, click Administration > Setup > User groups.
2. On the Groups tab, create a new group.
3. Enter an identification in the Group column (required). For example, Fin for Finance or HR for Human Resources.
4. Enter a name in the User group name column (required). For example, Finance Department or Human Resources Department.
5. Click the Users tab.
6. Select users in the Remaining users list and then click the left-arrow button (<) to move the selected users into the Selected users list. All users moved into theSelected users list are added to the current group.
7. Press CTRL+S to save changes.

Now that you have created one or more groups, you are ready to assign permissions. For information about how to assign permissions, see Manage security permissions for user groups and domain combinations.

How to Create a New Role Center in Dynamics AX 2009

How to Create a New Role Center in Dynamics AX 2009

One of the most talked about features of AX 2009 is Role Centers... I thought Microsoft did a
phenomenal job by packaging SharePoint and AX in one box... which resulted in really cool
technology.
As complex as they might seem role centers are actually very simple to use.. and its actually even
simpler to create new one..
This is a step by step guide to help users/developers to create and deploy new role centers..
In this example we are going to create a Merchandiser Role Center

Step 1:
Log in as an Admin and open up EP in internet explorer..

Well you actually don't need to be an admin.. but you need site creation rights in SharePoint and also access
to the AOT in AX.

Then click on ‘Site Actions’ and select the ‘Create’ option

Step 2: select Basic Page..

Note: you might be better of select ‘Web Part Page’.. as a basic page would not have any web parts
on it... all the standard role center pages are Web part pages... I will show you both examples in
this article .. hence I started with the basic page. (see the Additional info section below)
Also I like the basic page because it loads up a lot faster!

 Step 3: in the next page, type in the Name of the Page (please use good Naming Convention
Standard)... also make sure that the Document Library is set to Enterprise Portal

Step 4: as I choose to create a Basic Page a Text editor will pop up. if I would choose the Web
Part pages option then this editor would not appear.

Simply type something and click Save... now you would be directed to the new page.

Step 5: open the AOT in AX and browse down to the Web Menu Item Node .. right click and
select New URL.

Step 6: Give the URL a name and a Label (please follow std naming conventions) and then click
on the brose icon on the URL Property (the browse icon is represented by 3 dots).. as shown in
picture

Then expand the Enterprise Portal folder and find the new Page you created. Select and click OK

Step 7: make sure that you set the Home Page Property to Yes..
If you dont set this to yes, then the page will not be available is the role canter page list on the
User profile form (next step)

Save and close the AOT.

Step 8: in AX browse to Administration > Setup > User profiles
Create a new record, set the Profile name and description and then select the new Page as the role
centre page
Assign users to the role and your done.

Additional Info:
 You can also export the role centre (user Profile > Export and Export AOT).. the export
AOT options make the role centre a part of the AOT resource node.. this is helpful if you
want to migrate the role centre from say a dev environment to a Test Environment.
 To create a Web Part Role centre

Rather than selecting the Basic page option ..select the Web Part page option

Then give a name and select EP as the Document Library
Notice I choose to overwrite the role page .. this way I dint have to change my url to
point to the Web part page.
