Ora2Pg v21.1 released

Grenoble, France - April 1st, 2021

Ora2Pg

Version 21.1 of Ora2Pg, a free and reliable tool used to migrate an Oracle database to PostgreSQL, has been officially released and is publicly available for download.

This release fix several issues reported during the last six months and adds several new features and improvement.

• Now that Orafce 3.15.0 has a definition for the REGEXP_* functions makes the translation optional to USE_ORAFCE directive.
• Add set application name in connection to Oracle/MySql/PostgreSQL.
• Add translation of REGEXP_COUNT() and change assessment cost.
• Rewrite the way REGEXP_LIKE() is translated into regexp_match to support modifiers. This rewrite also fix default behavior between Oracle and PostgreSQL.
• Replace DBMS_LOB.GETLENGTH() by PostgreSQL octet_length() function.
• Add types correspondences for VARCHAR2 and NVARCHAR2 in DATA_TYPE configuration directive.
• Add autodetection and support of geometry type, srid and dimension for ArcGis geometries.
• Add conversion of default value in function parameters.
• Add -u | --unit option to ora2pg_scanner to be able to set the migration cost unit value globally.
• Replace DBMS_LOB.SUBSTR() by SUBSTR()
• Remove TO_CLOB() it is useless, manual cast could be necessary.
• Replace IS JSON validation clause in CHECK constraints by (CASE WHEN $1::json IS NULL THEN true ELSE true END) When the code is invalid an error is fired.
• DISTINCT and UNIQUE are synonym on Oracle.

Backward compatibility changes:

• Force a column to be bigint if this is an identity column. Thanks to MigOps.com for the patch.
• Fix EMPTY_LOB_NULL, enable/disable was inverted, keeping default to enabled. Take care that in old ora2pg.conf it is disabled so it will break backward compatibility with old configuration.
• Replace NO_LOB_LOCATOR with USE_LOB_LOCATOR and NO_BLOB_EXPORT with ENABLE_BLOB_EXPORT to avoid confusion with double negative variable. Backward compatibility is preserved with a warning.
• SRID for SDO_GEOMETRY export is now taken from the value not forced from the metadata table.
