使用ojdbc14 10.2.0.4 进行批量写入数据到oracle时,写入的字段有140个,每1000条执行一次executeBatch,日志中出现大量异常ArrayIndexOutOfBoundsException信息,具体以下:
java.lang.ArrayIndexOutOfBoundsException: -32377
at oracle.jdbc.driver.OraclePreparedStatement.setupBindBuffers(OraclePreparedStatement.java:2673)
at oracle.jdbc.driver.OraclePreparedStatement.executeBatch(OraclePreparedStatement.java:10689)
从日志信息来看,应该是oralce jdbc驱动内部setupBindBuffers方法中出现了数组越界异常。在网上找到一个帖子,通过他的思路得到了解决方案。
The 10g driver apparently keeps a global serialnumber for all parameters in the entire batch, with a "short"variable. So you can have at most 32768 parameters in the batch. I was havingthe same exception because I have a
INSERT statement with 42 parameters and mybatches can be as big as 1000 records, so 42000 > 32768 and this overflowsto a negative index. I reduced the batch factor to 100 to be safe, and all iswell. I guess your update DML should have a larger number of parameters
perrecord, right? (My diagnostic of the bug is just deduction from the symptoms)

按照这个思路,将addBatch的数量减少到100,使每次executeBatch的参数值小于32768,发现异常解决。
