Backing Up and Restoring Transactional Replication Using the sync with backup Option

Using sync with backup option

Ensures that Log Reader Agent will not send transactions to the distribution database

Allows restoration of databases

Restoring the publication database without using sync with backup option

Avoids increase in latency

Forcing the Distributor to Retain Content Until the Subscriber Has Backed Up

Recovery Strategies for Merge Replication

Restore Publisher and resynchronize with each Subscriber

Restore Publisher and Distributor and resynchronize with each Subscriber

Restore Distributor only

Drop and recreate subscriptions

Restore Subscriber database and resynchronize with each Publisher

Disaster Recovery Best Practices

Keep a script for replication

Link recovery to validation

Use reinitialization cautiously

Back up concurrently

Restore databases to their original server

Applying Service Packs to SQL Server 2000 Replicated Servers

Running in a mixed environment

You can replicate between a SQL Server with a service pack installed and a SQL Server without that service pack installed

Restoring after service pack upgrade

After applying a service pack, back up the log or full database

Replicating with Microsoft Access Subscribers

SQL Server 2000 Desktop Engine

Based on SQL 2000 technology

Most Access projects can run without revision

Microsoft Jet

Does not support case-sensitive sort order

Push and anonymous pull subscriptions

Supports rowcount validation only

Uses reserved column names

Replicating with Oracle Subscribers

Oracle subscription support

SQL Server has ODBC driver and OLE DB provider (Intel)

Must install Oracle’s SQL*Net driver on Publisher and Distributor

Replication restrictions

Table names cannot have spaces date data type maps to char(4)

Only one column of text or image data (long raw) SQL ranges for float and real differ from Oracle

Replicating with IBM DB2 Subscribers

DB2/AS400

OLE DB provider and ODBC driver are included with Microsoft Host Integration Server 2000

SQL Server Books Online has data mapping table

DB2/MVS

SQL Server Books Online has data mapping table

Other DB2 Systems

May require third-party ODBC drivers or OLE DB providers

Publishing from Heterogeneous Sources

Build applications with:

SQL Distributed Management Objects

Replication Distributor Interface

Third-party tools
