Question

我在Spring Batch应用程序中将HikariCP与oracle.jdbc.OracleDriver一起使用。当它在Oracle数据库中执行sql select查询时，第一个数据库会话将锁定另一个。我在数据库会话浏览器中看到它。因此我失去了并行查询执行的优势。

oracle.jdbc.OracleDriver 12.1.0.2.0
spring-jdbc-5.1.8
HikariCP-3.2.0
Oracle Database 12c企业版12.1.0.2.0版-64位

如何配置我的应用程序来解决此问题？

同时在多个作业的实例中使用相同的StepExecutionListener
