move primary

Changes the primary Replication Server for an error class or a function-string class.

Syntax

move primary
 of {[replication server] error class | function string class} class_name
 to replication_server

Parameters

replication server – Specify to modify a Replication Server error class. Leave out to modify a data server error class.
error class – Specifies that the primary Replication Server for an error class is to be changed.
function string class – Specifies that the primary Replication Server for a function-string class is to be changed.
class_name – The name of the error class or function-string class whose primary Replication Server is to be changed.
replication_server – Specifies the new primary Replication Server for the error class or function-string class. It is the name of the Replication Server where the command is executed, since move primary must be executed at the new primary Replication Server.

Examples

Example 1 – Changes the primary Replication Server for the pubs2_db_err_class error class to the SYDNEY_RS Replication Server. The command is entered at SYDNEY_RS:
```
move primary
   of error class pubs2_db_err_class
   to SYDNEY_RS
```
Example 2 – Changes the primary Replication Server for the Replication Server error class my_rs_error_class to the SYDNEY_RS Replication Server. The command is entered at SYDNEY_RS:
```
move primary 
   of replication server error class my_rs_error_class
   to SYDNEY_RS
```
Example 3 – Changes the primary Replication Server for the sqlserver2_function_class function-string class to the SYDNEY_RS Replication Server. The command is entered at SYDNEY_RS:
```
move primary
   of function string class sqlserver2_function_class
   to SYDNEY_RS
```

Usage

If you have changed the routing configuration, use move primary to ensure that error responses and function strings are distributed, via the new routes, to the Replication Servers where they are needed.
move primary must be executed at the new primary Replication Server.
move primary can be used to change the primary Replication Server from A to B only if routes exist from A to B and from B to A.
There is no primary site for the system-provided rs_sqlserver_function_class until you assign one. rs_default_function_class and rs_db2_function_class are system-provided, cannot be modified, and have no primary site.
The primary site for a derived function-string class is the site of its parent class, unless the parent class is rs_default_function_class or rs_db2_function_class. In that case, the primary site of the derived class is the site where it was created.
If you use rs_sqlserver_function_class, you must specify a primary site before you can modify a default function-string. To specify a primary site for the function-string class, execute create function string class rs_sqlserver_function_class at the primary site. Then use the move primary command to change the primary site for the class.
There is no primary site for the default error class, rs_sqlserver_error_class and rs_repserver_error_class, until you assign one. You must specify a primary site before you use assign action to change default error actions. To specify a primary site, execute create error class rs_sqlserver_error_class or create replication server error class rs_repserver_error_class at the primary site. Then you can use move primary to change the primary site.
