If logretain is set to "no" and userexit is set to "no", logs are not retained.

如果logretain设置成“No”并且userexit也设置成“No”，就不会保留日志。

For example, to set logretain to on, issue the command update db CFG using logretain on.

例如，要将logretain设置为on，应该发出命令update db cfg using logretain on。

You do not require userexit to be enabled when the logretain configuration parameter is enabled.

当启用了logretain配置参数时，就不需要启用userexit。
