Data is transported by programs to another location, and then loaded. A more efficient alternative to basic replication is to extract only the changes since the last processing cycle and transport\/apply those to the receiving location. In most cases, replication must not interfere with existing applications and have minimal impact on production systems. Thus, replication processes must be managed and monitored.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row module_class=” et_pb_row_fullwidth” _builder_version=”3.25″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” width=”89%” width_tablet=”80%” width_last_edited=”on|desktop” max_width=”89%” max_width_tablet=”80%” max_width_last_edited=”on|desktop” make_fullwidth=”on” column_structure=”1_2,1_2″][et_pb_column type=”1_2″ _builder_version=”3.25″ custom_padding=”|||” custom_padding__hover=”|||”][et_pb_text _builder_version=”3.27.4″]<\/p>\n What We Provide<\/span><\/p>\n XTIVIA\u2019s PostgreSQL DBAs start by connecting with your business to develop a PostgreSQL replication strategy.

\n[\/et_pb_text][et_pb_toggle title=”Shared Disk Failover” icon_color=”#3955a5″ admin_label=”Shared disk Toggle” _builder_version=”3.0.51″ title_font=”|on|||”]This method allows for rapid failover without data loss, while still having only one copy of the database. This method avoids any synchronization overhead by sharing a common disk between all database servers. If the main server fails, the standby server accesses the shared disk as though it was recovering from a database crash. The main point of failure is the shared disk array; if it becomes corrupt or unavailable, primary and standby are non functional. Also, only the primary server should have access to the storage while it is active.
\n[\/et_pb_toggle][et_pb_toggle title=”File System Replication” icon_color=”#3955a5″ admin_label=”File System Replication Toggle” _builder_version=”3.0.51″ title_font=”|on|||”]In this type of replication, hardware is shared, and all changes to the file system need to be mirrored on another server. The main challenge here is that primary file system mirroring is needed to guarantee the standby has a consistent copy of the file system. Writes to the file system need to be done in exactly the same order on the standby as they were on the primary.
\n[\/et_pb_toggle][et_pb_toggle title=”Hot\/Warm Standby Using \u201cPoint In Time Recovery\u201d (PITR)” icon_color=”#3955a5″ admin_label=”(PITR) Toggle” _builder_version=”3.0.51″ title_font=”|on|||”]Logs from the primary server are applied to the warm standby server. The standby can be made the new primary and would contain all the changes from the logs transferred before the failure. This method is asynchronous and can only be performed against the complete primary server.
\n[\/et_pb_toggle][et_pb_toggle title=”Master-Slave Replication” icon_color=”#3955a5″ admin_label=”master slave Toggle” _builder_version=”3.0.51″ title_font=”|on|||”]All queries that modify data are sent from the master asynchronously to the slave. In this setup, the slave is available for read only queries while the master is running.
\n[\/et_pb_toggle][et_pb_toggle title=”Statement-Based Replication Middleware” icon_color=”#3955a5″ admin_label=”Statement-Based Middleware Toggle” _builder_version=”3.0.51″ title_font=”|on|||”]Each server operates independently, while a middleware program captures each SQL query and forwards it to all or just one of the servers. Read-only queries can be sent to just a single server, allowing for a distributed workload. Read\/write queries are sent to all servers. Extreme caution should be used to make sure all transactions commit or abort on all servers. Also any application or middleware should be written in a manner so as to not use unmodified functions or sequences that could potentially return different values depending on which server was used.
\n[\/et_pb_toggle][et_pb_toggle title=”Asynchronous Multimaster Replication” icon_color=”#3955a5″ admin_label=”Asynchronous Multimaster Toggle” _builder_version=”3.0.51″ title_font=”|on|||”]Each server works on its own, communicating with the other servers to identify conflicting transactions. Rules are defined or users can resolve any conflicts. This works well in an environment where servers maintaining a constant connection is a challenge.
