java - Hibernate with HSQLDB and Oracle -

-

i have moved group of tables hsqldb faster performance, there few residual many 1 associations between hsqldb tables , oracle tables. possible configure hibernate manage type of association? i'm using 2 persistence units, 1 oracle , other hsqldb.

hibernate not support relationships between different databases , not databases of different types.

you have manage "fetch" of related entities hand, perhaps converting many-to-one raw foreign key values , doing fetch oracle db (using different sessionfactory if using hibernate both).
