OpenJPA's implementation (TableJDBCSeq) of the table based sequence
generation stores the sequence state in a table called
OPENJPA_SEQUENCE_TABLE. There can be one counter over all entities or a
separate counter per entity class.

How are you experiences with many JPA applications (n >> 1) using the table
strategy with a single shared DB2 schema?

Won't there be locks on the OPENJPA_SEQUENCE_TABLE when multiple
applications select their new sequence values? If using a separate counter
per entity class, will there be at least only locks per row (and not per
table)?

TIA,
Tobias
