spring批量插入oracle数据库问题

Question

I have a spring batch example where I read from a Flat file and write into Oracle database. when I create the oracle table the first time using Oracle developer , the example work perfect , but when I delete all the records and run the spring batch example the application stay in running mode (stop at the point wher insert in table) and not finish until I manually (using oracle SQL Developer ) add a record in the table , so it s continue running and complete perfectly . Is that have a problem with the table that I'm using in oracle (I m not an expert in oracle database). any help or suggestion please?

When you run the spring batch from the application, are you committing your changes? When you are doing large batch operations in Oracle, the database will place a lock on the table until the transaction is either committed or rolled back . If you are not doing that when you run your batch from within the application, my guess is that whatever you're doing from the application side is placing a lock on the table, and said lock is not removed until you manually commit your changes by adding a record to the table. Try adding a commit point at the end of your application process to test.
