Changes a parameter of a replication agent profile stored in the MSagent_parameters system table. This stored procedure is executed at the Distributor where the agent is running, on any database.
Transact-SQL Syntax Conventions
sp_change_agent_parameter [ @profile_id= ] profile_id, [ @parameter_name= ] 'parameter_name', [ @parameter_value= ] 'parameter_value'
[ @profile_id = ] profile_id,
Is the ID of the profile. profile_id is int, with no default.
[ @parameter_name = ] 'parameter_name'
Is the name of the parameter. parameter_name is sysname, with no default. For system profiles, the parameters that can be changed depend on the type of agent. To find out what type of agent this profile_id represents, locate the profile_id column in the Msagent_profiles table, and note the agent_type value.
Note
If a parameter is supported for a given agent_type, but has not been defined in the agent profile, an error is returned. To add a parameter to an agent profile you must execute sp_add_agent_parameter.

To see what parameters have been defined for a given profile, run sp_help_agent_profile and note the profile_name associated with the profile_id. With the appropriate profile_id, next run sp_help_agent_parameters using that profile_id to see the parameters associated with the profile. Parameters can be added to a profile by executing sp_add_agent_parameter.
[ @parameter_value = ] 'parameter_value'
Is the new value of the parameter. parameter_value is nvarchar(255), with no default.
0 (success) or 1 (failure)
sp_change_agent_parameter is used in all types of replication.
Only members of the sysadmin fixed server role can execute sp_change_agent_parameter.
