Syntax

sp_change_agent_parameter [ @profile_id= ] profile_id, [ @parameter_name= ] 'parameter_name', [ @parameter_value= ] 'parameter_value'

Arguments

  • [ @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.

    For a Queue Reader Agent (agent_type=9), if defined in the profile, the following properties can be changed:

    • HistoryVerboseLevel
    • LoginTimeout
    • Output
    • OutputVerboseLevel
    • PollingInterval
    • QueryTimeout

    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.

Return Code Values

0 (success) or 1 (failure)

Remarks

sp_change_agent_parameter is used in all types of replication.

Permissions
