Question

我们正在迭代中测试我们的sql：SELECT a b from c left join d on ... where e = ?。有很多测试，但只有一个（仍然相同）有时会失败 ora: 03115 。数据仍然相同。

error code [3115]; ORA-03115: unsupported network datatype or representation

我正在使用ojdbc6和oracle 11：

Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - Production
PL/SQL Release 11.1.0.6.0 - Production
"CORE   11.1.0.6.0  Production"
TNS for Linux: Version 11.1.0.6.0 - Production
NLSRTL Version 11.1.0.6.0 - Production

我读到了这个错误，但没有解释有时它失败了，有时不是在条件相同时。错误只出现几次（90％OK 10％失败）。知道为什么会这样吗？

org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL []; 
SQL state [63000]; error code [3115]; ORA-03115: unsupported network datatype or representation
; nested exception is java.sql.SQLException: ORA-03115: unsupported network datatype or representation

PS：这与将其标记为重复的问题没有任何共同之处。在我的选项中，此问题有时并不总是如上例所示。我正在使用spring jdbc：

PreparedStatementCreator psc = new PreparedStatementCreator() {
            @Override
            public PreparedStatement createPreparedStatement(Connection con) throws SQLException {
                PreparedStatement ps = con.prepareStatement(query);
                if (timeout != null)
                    ps.setQueryTimeout(timeout);
                if (fetchSize != null)
                    ps.setFetchSize(fetchSize);
                return ps;
            }
        };
        PreparedStatementSetter pss = new PreparedStatementSetter() {
            @Override
            public void setValues(PreparedStatement ps) throws SQLException {
                setParameters(ps, limitType, 1);
            }
        };
        ResultSetExtractor<List> rse = new ResultSetExtractor<List>() {
            @Override
            public List extractData(ResultSet rs) throws SQLException, DataAccessException {
                if (fetchSize != null)
                    rs.setFetchSize(fetchSize);
                return getResults(rs);
            }
        };


            List list = jdbcTemplate.query(psc, pss, rse);
            if (logger.isDebugEnabled()) {
                logger.debug("list, number of returned rows=" + ((list != null) ? list.size() : "null"));
            }
            return list;

为什么ORA-03115有时会出现在jenkins
