Symptoms

Issue occurs with tables created with COMPRESS for OLTP. When the table is
loaded using a PL/SQL BULK COLLECT and INSERT (as well as Peoplesoft script), some LCRS get generated with NULL values or wrong data for columns defined with a NOT-NULL constraint.

LCRS may fail to apply at the target database with an ORA-1400 which is expected if NOT-NULL constraint exist.

A print transaction of the LCR shows the corresponding column has a NULL value.

The logminer output for the corresponding transaction also shows the insert contains a NULL value for the column but the insert executed at the source insert the correct data on the table.

Data in redo logs are correct, just the handling by logminer is incorrect.

Changes

Use of bulk collect and/or insert on OLTP compressed table
