Problem: Oracle error "ORA-01000: maximum open cursors exceeded"

Check if the maximum cursor limit in the database is at least (RelationalDatabaseConnection.statementCacheSize + 10):

To check the value, run the following:

select value from v$parameter where name='open_cursors';

If not, set it as follows (assuming that statementCacheSize=1000):

alter system set open_cursors=1010 scope=both;
