4.2 Initial Release 19.1.0.0.0 — August 2019

Bug 29761322 - Oracle: Multibyte CLOB encoding is incorrect when Extract writes 12.2 trail format after software upgrade to 18.1 or later.

When the Extract writes a multibyte CLOB data to the trail in the same format as the existing trail file format, the Extract writes MBCS CLOB data in an incorrect encoding. This happens in either of the following cases: when the trail file format is 12.2 or older, or the FORMAT RELEASE used to specify a format is older than 12.2.

Workaround: Perform an explicit ETROLLOVER after the software upgrade if the current trail file format is 12.2 and there are multibyte CLOBs.
