SAP ASE Log Problems

The SAP ASE primary database log is the source of the data that SAP Replication Server distributes. An SAP ASE RepAgent retrieves transactions from the log and sends them to the SAP Replication Server.

SAP ASE log problems include:

Log files that have reached the maximum size and need to be truncated
Missing or incomplete transactions at the primary SAP Replication Server as a result of truncated primary database logs
Log files corrupted by software and hardware sources

Truncating an Adaptive Server Log
Truncate the database log when it is too full to allow Adaptive Server to continue processing updates.
Database Log Locater
When a RepAgent starts, it uses a locater to determine where to begin scanning the database log. The locater for a database log is stored in the rs_locater table in the Replication Server System Database (RSSD) of the Replication Server that controls the database.
Log Truncation Problems
Inconsistencies may occur when the primary database log is truncated.
Symptoms of a Corrupted Adaptive Server Log
Adaptive Server log corruption can cause failures anywhere along the replication path.
