I was having problems with installdb using oracle 10g XE on a windows box. During upgradedatabase an exception was being thrown with oracle error ORA-01000: Too many open cursors. The exception stack showed the problem to be in org.aspcfs.modules.service.base.SyncTable where PreparedStatements where being executed but not closed.
After closing the PreparedStatements, the installdb was able to complete.
