# mco_HA_enable_filter

This function turns on/off partial replication.

### For an overview see page HA Applications

### Prototype

        void	mco_HA_enable_filter (	Mco_db_h db,
                        Mco_bool enable)

### Arguments

db | The database connection handle.
enable | `MCO_YES` or `MCO_NO` to turn partial replication on or off.

### Description

This function is called by either the master or replica to turn on/off partial replication. If local tables are defined, filtering is on by default. Consequently `mco_HA_enable_filter(db, MCO_NO);` turns filtering off. If the schema does not define local tables, this function has no effect.

### Return Codes

MCO_S_OK | Successful.
