Reading Franck Pachot blog about comparing source and target in a Dbvisit replication (http:\/\/dbi-services.com\/blog\/compare-source-and-target-in-a-dbvisit-replication\/<\/a>), I decide to write a small article about how we can do same thing with SharePlex. Indeed SharePlex provides built-in commands to compare<\/span> and repair<\/span> synchronization.
\nBelow is our configuration file. We are just replicating table article to article_rep. Both tables contain 2000000 rows

From the source let\u2019s insert 2 rows to verify that replication is working fine.<\/p>\n

We see that tables are in sync. When running the compare command, SharePlex obtains a brief exclusive lock on the source table to get read consistency for its row selection.
\nOn the target system, SharePlex obtains an exclusive lock on the target table and retains the lock for the duration of the comparison of that table.
\nNow let\u2019s Sync out our replication
\nFrom the target let\u2019s delete a row (note that we have one directional replication only from source to target)<\/p>\n

Conclusion<\/h4>\n

We will retain that SharePlex provides powerful commands compare\/repair<\/span> to fix out of synchronization. Just note that during execution of these commands tables are locked (briefly on the source and more on the target) meaning that no transaction will not be possible during this period.
\nNote that the compare and repair commands can also be used for initial load (not recommended because of locks).<\/p>\n
