Version 2.2 v2
LiveCompare 2.2 includes the following new features, enhancements, and bug fixes:
| Type | Description | ID |
|---|---|---|
| Feature | Added --dry-run execution mode, which allows users to validate the .ini file and view some useful comparison information, without running comparison session. See Dry-run mode for more information. | LIV-142, RT78462 |
| Feature | Any abort messages received during the comparison session are printed in chronological order. | |
| Feature | Displays the list of connections, including technology, version, if the connection is a tiebreaker or a source of truth, and if it's reachable. | |
| Feature | Displays the Table Filter if it is configured. | |
| Feature | Lists the tables that are included in the comparison. This is the list of common tables that exist across all connections, after applying the Table Filter. For each table, shows the Column Filter, Row Filter and Comparison Key, if applicable. | |
| Enhancement | Support for SLES 12 on x86_64. | LIV-112 |
| Enhancement | Support for SLES 15 on x86_64. | LIV-113 |
| Enhancement | Updated the list of reserved words according to Postgres kwlist source code. | LIV-141, RT80745 |
| Enhancement | The main progress bar percentage is now using a float instead of an integer. Previously, the number was rounded up. | LIV-138, RT80745 |
| Enhancement | When edb_redwood_date is enabled in EPAS, the date columns are created as timestamp columns. This type mismatch was previously detected as a mismatch in the Common Hash, which triggers a full row comparison. Performance is improved by handling this mismatch in the Common Hash (which is faster than a full row), by checking the edb_redwood_date setting in these cases. | LIV-153 |
| Enhancement | Demoted hash mismatch log messages from WARNING to DEBUG. | LIV-145 |
| Enhancement | Logs now include the application_name in the message. | LIV-141 |
| Enhancement | Documented the behavior of using the current timestamp in Row Filter on Postgres or EPAS when data_fetch_mode = prepared_statements (the default). In this situation, it's also required to set data_fetch_mode = server_side_cursors_with_hold or server_side_cursors_without_hold. | LIV-155 |
| Enhancement | Improved performance when generating the apply DML scripts when there is an increased number of divergences detected. | LIV-159 |
| Bug fix | Fixed a problem where an array column being considered as a Comparison Key caused the comparison on a table to be aborted due to an exception. | LIV-38, LIV-154, RT81758 |
| Bug fix | A problem was resolved where the number of divergent and processed rows was not being properly updated after the comparison round, only by a Heart Beat. In this case, the rows were outdated, showing only the position since the last Heart Beat. For tables where the comparison took less than min_time_between_heart_beats, it would always indicate zero. | LIV-149, RT75805 |
| Bug fix | Fixed a corner case where unhandled exceptions could cause the comparison worker to hang. | LIV-140, RT80745 |
| Bug fix | Normalizing decimal values to avoid false positives when comparing Oracle versus Postgres. | LIV-153 |
| Bug fix | Fix a corner case in which if comparison_algorithm = block_hash and buffer_size = 1, and there were any divergences found, the comparison would not advance due to an issue in the cursor advancing algorithm. | LIV-150 |
| Bug fix | Allow the same table to be configured in multiple filter sections. | LIV-156 |
