IBM Tivoli Directory Server 6.0 - Replication Excerpt taken from presentation given on April 24, 2007 Planning strategies involved in setting up an IBM Tivoli Directory Server replication topology
Introduction
Introduction Abstract: This STE will discuss replication at ITDS 6.0 and will cover topics such as planning your topology, implementing replication in environment, and troubleshooting replication errors Objectives: Planning an effective topology Implementation with both webadmin and command line Best replication debugging practices

A pot file is a Design Template file, which provides you the “look” of the presentation You apply a pot file by opening the Task Pane with View > Task Pane and select Slide Design – Design Templates. Click on the word Browse… at bottom of Task Pane and navigate to where you stored BlueOnyx Deluxe.pot (black background) or BluePearl Deluxe.pot (white background) and click on Apply. You can switch between black and white background by navigating to that pot file and click on Apply. Another easier way to switch background is by changing color scheme. Opening the Task Pane, select Slide Design – Color Schemes and click on one of the two schemes. All your existing content (including Business Unit or Product Names) will be switched without any modification to color or wording. Start with Blank Presentation, then switch to the desired Design Template Start a new presentation as Blank Presentation You can switch to Blue Onyx Deluxe.pot by opening the Task Pane with View > Task Pane and select Slide Design – Design Templates. Click on the word Browse… at bottom of Task Pane and navigate to where you stored BlueOnyx Deluxe.pot (black background) and click on Apply. Your existing content will take on Blue Onyx’s black background, and previous black text will turn to white. You should add your Business Unit or Product Name by modifying it on the Slide Master You switch to the Slide Master view by View > Master > Slide Master. Click on the Title Page thumbnail icon on the left, and click on the Business Unit or Product Name field to modify it. Click on the Bullet List Page thumbnail icon on the left, and click on the Business Unit or Product Name field to modify it. Click on Close Master View button on the floating Master View Toolbar You can turn on the optional date and footer fields by View > Header and Footer Suggested footer on all pages including Title Page: Presentation Title | Confidential Date and time field can be fixed, or Update automatically. It appears to the right of the footer. Slide number field can be turned on as well. It appears to the left of the footer.

Why would I use replication?
Why would I use replication? To provide failover functionality in case of a catastrophic hardware or software loss - Redundancy Balance read traffic Allow offline backup without taking an outage Application balancing Read only to the public, read-write to the private networks
Planning an effective replication topology
Planning an effective replication topology Identify systems for use which meet the requirements to run ITDS 6.0 (consult the ITDS 6.0 Install Guide) Plan the correct physical layout - Firewall vs Public - Application needs Effectively plan how to direct traffic at a SINGLE master for write traffic - Load Balancer configuration - Correct application configuration
Types of Topologies
Types of Topologies There are 4 basic replication topologies: Peer to Peer Supplier to Consumer Gateway Replication Forwarders For this class we will discuss the most common topologies of Peer to Peer and the Supplier to Consumer configurations
Peer to Peer – vs – Master/Consumer
Peer to Peer – vs – Master/Consumer In a Peer to Peer relationship each ITDS server has both read and write access to the data Should Peer1 fail Peer2 will keep track of all changes made and will update Peer1 when it is recovered In a Supplier/Consumer relationship only the Supplier has read and write access to the data, while the Consumer is a read-only server.
