You can choose to maintain a transaction log mirror when you create a database. This option is available from the CREATE DATABASE statement, from Sybase Central, or from the dbinit utility.

For more information about why you may want to use a transaction log mirror, see Transaction log mirrors.

♦  To create a database that uses a transaction log mirror (Sybase Central)

1. From the Tools menu, choose SQL Anywhere 11 » Create Database.

2. Follow the instructions in the Create Database Wizard.

♦  To create a database that uses a transaction log mirror (SQL)

• Use the CREATE DATABASE statement, with the TRANSACTION LOG and MIRROR clauses. For example:

  CREATE DATABASE 'c:\\mydb' TRANSACTION LOG ON mydb.log MIRROR 'd:\\mydb.mlg';

  See CREATE DATABASE statement.

♦  To create a database that uses a transaction log mirror (command line)

• Use the dbinit utility with the -m option. For example, the following command (which should be entered on one line) initializes a database named company.db, with a transaction log kept on a different device and a mirror on a third device.

  dbinit -t d:\log-dir\company.log -m e:\mirr-dir\company.mlg c:\db-dir\company.db

  See Initialization utility (dbinit).
