Symptoms
When a transaction as examined by Logdump, contains transient primary Key updates and compressed updates, various update error occur. Unique Key or Primary Key constraints violations are common errors seen in Replicat report file. The replicat is moving keys as it is updating them and may lose track of them if the table is not set up correctly.
Changes
The problem is limited to tables in which the key columns was updated by using transient update statement, such as "update <table name> set <keycol> = <keycol> +1 ". This will cause the key columns value to be increased to one higher for each row or a set of rows depends on the where clause.
