High Availability API

Please use the links below to view Reference Guide pages for the eXtremeDB High Availability API functions:

mco_HA_async_send_data_to_replicas Send transaction data from master buffer to replicas

mco_HA_attach_master Perform handshaking with the master, load the master’s current state (database), and wait to accept transactions from the master

mco_HA_attach_replica Wait for a connection request from a replica

mco_HA_cancel Instantly interrupt the replication processing

mco_HA_commit_window Force replicas to confirm a transaction package (window)

mco_HA_create_cancel_socket Create a cancel socket that can be used in the application

mco_HA_destroy_cancel_socket Close an explicitly created cancel socket

mco_HA_detach_all_replicas Detach (disconnect) all connected replicas

mco_HA_detach_replica Detach (disconnect) the replica identified by the channel pointer

mco_HA_enable_filter Turn on/off partial replication

mco_HA_get_channel_info Get information about the I/O channel

mco_HA_get_current_auto_oid Get the current auto_oid value

mco_HA_get_io_channel Get the I/O channel of the replica referenced by the master database handle and the index of the replica

mco_HA_get_ip_addr Get the IP address associated with the specified I/O channel

mco_HA_get_number_of_replicas Get the count of replicas currently attached

mco_HA_get_port Get the port associated with the specified I/O channel

mco_HA_get_mode Get the MCO_HAMODE_* value specified for this database

mco_HA_get_sequencer Get the number of the "db version" (or "current-ness" in the sense of HA)

mco_HA_keep_alive Send the KEEP_ALIVE signal to replicas

mco_HA_master_params_init Initialize the master HA runtime parameters to default values

mco_HA_replica_params_init Initialize the replica HA runtime parameters to default values

mco_HA_replica_stop Cause a local asynchronous stop request to be sent from the standby application

mco_HA_set_master_params Set the master HA runtime parameters

mco_HA_set_trans_window_size Set the transaction packet (window) size

mco_HA_set_quorum Set the HA quorum at runtime

mco_HA_start Initialize the HA subsystem

mco_HA_stop Shutdown the HA subsystem
