The maximum number of operations the Log Reader component reads during each log scan operation.
1000
An integer from 25 to 2147483647.
The value of the max_ops_per_scan parameter is the maximum number of database operations that can be read from the Replication Agent transaction log during each Log Reader scan operation (the size of the Log Reader operation queue).
The Log Reader component always reads at least one transaction in each scan, regardless of how many operations are in the transaction.
For example, if the value of the max_ops_per_scan parameter is 1000, and a transaction contains 1200 operations, the Log Reader component reads all 1200 operations in one scan when it reads that transaction.
See the Sybase Replication Agent Database Guide for more information about how the max_ops_per_scan parameter affects Replication Agent performance.
