Depending on your WebSphere Application Server version and patch level, automatickeygeneration might be on or off by default; the more recent the version, the more likely it is off by default.
As a result, if you rely on database sequences (such as for automatic primary keygeneration), it's likely that an identical primary key will show up across a set of databases.
因此,如果您依赖于数据库序列(如自动主键生成),很有可能在一个数据库集中将出现同一个主键。
