SQL迁移日志

SQL DSC（DSC.jar）支持以下类型的日志记录：

  • 活动日志
  • 错误日志
  • 成功读
  • 成功写
  • 如果用户指定了日志路径，所有日志都会保存在该路径下。
  • 如果未指定日志路径，DSC会在TOOL_HOME路径下创建log文件夹，用于存储所有日志。
  • 为控制磁盘空间用量，日志文件的大小上限为10 MB。用户最多可拥有10个日志文件。
  • 工具日志不记录敏感数据，如查询。

活动日志

DSC将所有日志和错误信息保存到DSC.log文件中。该文件位于log文件夹中。DSC.log文件包含执行迁移的用户、迁移的文件、时间戳等详细信息。活动日志的记录级别为INFO。

DSC.log的文件结构如下：

错误日志

DSC仅将迁移过程中发生的错误记录到DSCError.log文件中。该文件位于log文件夹中。DSCError.log文件包含这些错误的日期、时间，文件详细信息（如文件名），以及查询位置等信息。错误日志的记录级别为ERROR。

DSCError.log的文件结构如下：

2017-06-29 14:07:39,585 ERROR TeradataBulkHandler:172 Error occurred during processing of input in Bulk Migration. PreQueryValidation failed in not proper termination or exclude keyword. /home/testmigration/Documentation/Input/c005.sql for Query in position : 4

成功读

在DSC读取文件之后，该文件将被记录日志以进行跟踪。在某些情况下，用户可通过这些日志获取文件执行状态的信息。该文件位于log文件夹中。日志文件包括日期、时间、文件名等详细信息。此日志文件的日志记录级别为INFO。

successRead.log的文件结构如下：

2017-07-21 14:13:00,461 INFO readlogger:213 /home/testmigration/Documentation/is not in.sql is read successfully.
2017-07-21 14:13:00,957 INFO readlogger:213 /home/testmigration/Documentation/date quotes.sql is read successfully.

2017-07-21 14:13:03,145 INFO readlogger:213 /home/testmigration/Documentation/2.6BuildInputs/testWithNodataSamples.sql is read successfully.

成功写

DSC读取、处理文件并将输出写入磁盘。这个过程被记录到成功写日志文件中。在某些情况下，用户可通过此文件了解哪些文件已处理成功。在重新运行的情况下，用户可以跳过这些文件运行剩余的文件。该文件位于log文件夹中。日志文件包括日期、时间、文件名等详细信息。此日志文件的日志记录级别为INFO。

successWrite.log的文件结构如下：

2017-07-21 14:13:00,616 INFO writelogger:595 /home/testmigration/Documentation/is not in.sql has written successfully.
2017-07-21 14:13:01,055 INFO writelogger:595 /home/testmigration/Documentation/date quotes.sql has written successfully.
