Applies to:JDBC - Version 126.96.36.199 and later
Information in this document applies to any platform.
A JDBC application peforms an XA transaction using 2 XA data sources.
One XA data source uses an isolation level of Serialized.
The other XA data source uses an isolation level of Read Committed.
If the 2 data sources are pointing to 2 different databases then the 2nd data source behaves as expected. ( the second transaction can see changes from the the first transaction )
If the 2 data sources are pointing to 2 different schemas but on the same database then the 2nd XA data source behaves as if it is Serialized instead of Read Committed. ( the second transaction cannot see changes from the the first transaction ) .
Different transaction isolation behavior depending on whether the two XA connections are from different databases or from the same database.
