Creating a Replication Agent Instance Using the Command Line

Create a Replication Agent instance from the Windows or UNIX command line.

Prerequisites

Set the SYBASE environment before you invoke ra_admin.

Task

On the Replication Agent host machine, open an operating system command window.
Navigate to the Replication Agent bin directory:
- On Windows platforms:
  cd %SYBASE%\RAX-15_5\bin
  where %SYBASE% is the path to the Replication Agent installation directory.
- On UNIX platforms:
  cd $SYBASE/RAX-15_5/bin
  where $SYBASE is the path to the Replication Agent installation directory.
In the Replication Agent bin directory, invoke ra_admin to create a new Replication Agent instance:
```
ra_admin -c new_inst -p port_num -t database
```
where:
- new_inst is the name of the new Replication Agent instance.
- port_num is the client socket port number for the administration port of the new instance. For Oracle and Microsoft SQL Server, be sure that a second port, port_num+1, is available for the RASD.
- database identifies the type of data server that the primary database resides in:
  
  oracle – Oracle database server
  
  mssql – Microsoft SQL Server (valid only on Microsoft Windows platforms)
  
  ibmudb – IBM DB2 for Linux, UNIX, and Windows
After you invoke ra_admin, the operating system prompt returns when the new Replication Agent instance is created.
Verify that the Replication Agent instance was created properly using one of these methods:
- Invoke ra_admin with the -v option, and specify the name of the Replication Agent instance:
  ra_admin -v new_inst
  where new_inst is the name of the Replication Agent instance.
  When you verify a Replication Agent instance with the -v option, the utility verifies the instance by checking for an instance directory with the specified instance name under the Replication Agent base directory, and checking all of the subdirectories under the Replication Agent instance directory.
- Invoke ra_admin with the -l option:
  ra_admin -l
  The -l option lists all verifiable Replication Agent instances, which should include the new one you just created.
- As an alternative to using ra_admin, you can use operating system commands to verify that the Replication Agent instance directories were created correctly.

After you create a Replication Agent instance, you can use ra to start the instance so that you can administer and configure it.

Note: Sybase recommends that you create a user login name and password to replace the default “sa” login and secure access to the administration port, immediately after you create a Replication Agent instance.
