管理错误也可能导致意外删除重要的文件，比如在清理旧日志时，意外地删除了数据库的活动事务日志。
Administrative error can also cause important files to be inadvertently deleted, such as accidentally removing the active transaction log of a database while cleaning up the old logs.
该进程为可恢复的数据库管理日志文件。
在选择同步还是异步写日志时，要考虑的一个重要因素就是当数据库管理器发生错误时情况会怎样。
An important factor to take into account when selecting between synchronous or asynchronous log writing is what happens when a database manager error occurs.
当数据库管理器关闭日志文件时，会归档日志文件。
Log files are archived when the database manager closes the log file.
只要涉及到资源管理器和库服务器数据库，一旦有了一次原始备份，并且所有日志均完好无损，即可保证不损失任何数据。
As far as Resource Manager and Library Server databases are concerned, once you have a baseline backup and all logs are intact, there is a guarantee that there will be no loss of data.
该参数使数据库管理器调用用户出口程序来归档和检索日志。
This parameter causes the database manager to call a user exit program for archiving and retrieving logs.
该延迟可以有助于减少与写日志记录相关的数据库管理器开销。
This delay can help reduce the database manager overhead associated with writing log records.
注：数据库管理器每次写一个事务日志。
Note: The database manager writes to transaction logs one at a time.
对于每个数据库来说，调优参数、资源管理和日志会有所不同，并且可以在数据库级别上对其进行控制。
Tuning parameters, resource management, and logging can differ for each database and can be controlled at the database level.
为了构建这个日志框架，需要数据库管理员帮我们设置存储过程的日志目录并创建一个用户临时表空间。
In order for you to set up the logging framework, you will need help from your database administrator to set up the stored procedure logging directory and a user temporary table space.
它可以对一些数据库事件，例如授权检查、数据库对象维护、安全性维护、系统管理和用户验证等做日志记录。
It is capable of logging database events such as authorization checking, database object maintenance, security maintenance, system administration, and user validation.
另一半是称作预写式日志记录(write - ahead logging)的数据库管理器实现。
The other half is a database manager implementation called write-ahead logging.
通过将数据库管理器参数 AUDIT_BUF_SZ的大小设置为40，确保审计功能将使用异步日志记录
You ensure that the audit facility is using asynchronous logging by setting the size of the AUDIT_BUF_SZ database manager parameter to 40
运行数据包括WebSphere事务日志、与流程服务器数据库关联的一些文件以及与任何其他资源管理器关联的一些文件。
The run data consists of the WebSphere transaction logs; some of the files are associated with the process server databases and some of the files are associated with any other resource managers.
当需要第六个日志文件时，数据库管理器将检查logsecond值并将另一个日志文件分配到日志目录。
When the sixth log file is needed, the database manager will check the logsecond value and allocate another log file to the log directory.
为了保持logprimary值，数据库管理器将根据前一个事务中使用了多少日志文件来分配新的日志文件。
In order to preserve the logprimary value, the database manager will allocate new log files based upon how many log files were used in the previous transaction.
在这种情况下，数据库管理器会删除logpath目录中的所有日志文件(包括联机归档日志文件)，分配新的活动日志文件，并且回复到循环日志记录。
In this situation, the database manager deletes all log files in the logpath directory (including online archive log files), allocates new active log files, and reverts to circular logging.
在这种情况下，数据库管理器会删除logpath目录中的所有日志文件(包括联机归档日志文件)，分配新的活动日志文件，并且回复到循环日志记录。
In this case, the database manager deletes all log files in the logpath directory (including online archive log files), allocates new active log files, and reverts to circular logging.
