AX 2012 OVERVIEWPresented by Vishy Grandhi

Lesson 1: AX Overview Lesson 2: Role based security Lesson 3: Monitoring Troubleshooting

Training Outline

At the end of this lesson you will have an understanding about◦ The components of an AX system◦ Extended System architecture◦Model driven architecture

AX Overview: Objectives

AX is a 3-tier system consisting of the following components◦ Database (SQL Server)◦ AOS (Business logic execution service)◦ Client (AX Rich client, EP, .NET Business

Connector)

AX Overview: AX Components

AX Database◦ It is an OLTP db◦ Stores business data◦ Stores Metadata and application code

AX Overview: AX Components

AOS◦ Application object server◦ It provides a runtime for execution of X++ code◦ Manages security◦ Session management◦ Web services end point

AX Overview: AX Components

Clients◦ AX Rich client installed on client

desktop/citrix/RDP◦ Enterprise Portal◦ Microsoft Office products (Through Dynamics AX

add-on)◦ .NET Business Connector

AX Overview: AX Components

AX Overview: System Architecture

AX has a unique model and layer architecture that enables easy customization while ensuring protection of code and easy upgrade◦ Layers◦ Models

AX Overview: Model driven architecture

AX Overview: Layers

Model is a new concept in AX 2012◦ Logical separation of code objects◦ Multiple ISV code segregation◦ Multiple project code segregation

AX Overview: Models

We have looked at the components that make up AX System

Architecture of AX – Layers and Models Extended system architecture

AX Overview: Wrap-up

At the end of this lesson you will have an understanding about◦ Role based security◦ Roles assignment to users

Role based security: Objectives

Role based security : Hierarchy

Role based security : Example

Entry Points Permissions Privileges Duties Roles

Role based security : Definitions

Menu items Web content items Service operations SSRS reports

Role based security : Entry Points

Process cycles are used in rich client to make it easier for a system administrator to view and find related duties when setting up security.◦ Conversion cycle◦ Cost accounting cycle◦ Expenditure cycle◦ Human capital management cycle◦ Information Technology cycle◦ Revenue cycle

Role based security : Process Cycles

At the end of this lesson you would have a good understanding of the following◦ Setup a new user◦ Assign the user appropriate role◦ Modify roles, duties and privileges

Setup new user: Objectives

At the end of this lesson you will have an understanding about◦ Monitoring Hardware◦ Monitoring Database◦Monitoring Dynamics AX

Monitoring: Objectives

Use System Monitor (Perfmon) to monitor Windows, SQL Server and AX Counters. A few important counters

Monitoring: Hardware

– % Privileged Time– % Processor Time– Available Mbytes– Page Faults/sec– Avg. Disk Queue

Length– % Disk Time– Bytes Total/Sec– Buffer Cache Hit Ratio

(Sql)– User Connections

– SQL Compilations– Active Sessions (AX)– Total Sessions– Number of client

requests– Fatal session

exception (EP)– Session allocation

rate– Web part execution

rate

SQL Server Profiler can be used to identify performance issues with queries, any deadlocks and general tracing.

Monitoring: Database

• A few events for tracing– Deadlock– Data File Autogrow– Log File Autogrow– Showplan XML– Sp:StmtStarting/

Completed– Sql:StmtStarting/

Completed

• Problems that can be detected include– High number of

reads/writes– Long running queries– Execution plans

Other tools available include◦ SQL Dynamic Management Views◦ Sp_who, sp_lock◦ DBCC CACHESTATS, DBCC TRACEON, DBCC

TRACEOFF, DBCC TRACESTATUS◦ SQLIO – Disk performance test tool◦ SQLIOSim – Disk Stress Test Tool◦ SQL Server logs

Monitoring: Database

AX Trace Parser

Monitoring: Dynamics AX

Common performance related issues that are noticed in Dynamics AX

Troubleshooting: Overview

– Blocking and deadlocking

– Disk I/O bottlenecks– High CPU utilization– Large number of

roundtrips to database– High memory usage

when run in IL

• Problems that can be detected include– High number of

reads/writes– Long running queries– Execution plans

The following recipes are included in this presentation◦ Create a new user◦ Assign role to a user

Recipes: List of recipes

administrator profile in Same profile in all companies. This defines Vishy's role center.

15. Click Next.16. Click Finish

Recipe: Create a new user

1. Open the Microsoft Dynamics AX client.

2. Go to System Administration > Common > Users > Users.

3. Double-click Vishy Grandhi in the grid to edit his record.

4. Click Assign roles in the User's role section of the form.

5. Select Accounts receivable manager and click OK.

6. Finish.

Recipe: Assign role to a user

We have looked at AX components and system architecture

We have also explored model driven architecture

We have looked at Role based security in AX We explored the different security elements Finally we created a new user and assigned

him/her roles
