In the morning to the data center, see IBM's small machine and storage, recorded the system parameters and configuration, began to reload the system, partition LVM, and bare devices.

5. Process Auto-increment fields in database tables For a table containing auto-increment fields to be loaded, that is, the ixf data file of the table contains the value of auto-increment columns, you can add the following parameters to the load command to control the auto-increment field values:1). modified by identityignore: The loaded data file contains the auto-increment field value. During load, the auto-increment field value in the data file is

I recently did not find any tutorials for getting started on Ruby on Rails. The others are all download of e-books, and the existing notes are just the most basic. Or some configuration tutorials. I read some information in practical rails social networking sites Ruby on RALs and thought it was good. I 'd like to write it out and share it with you.

For a long time, data migration or extraction between heterogeneous databases is required. If Oracle Data is extracted from SQL, You Can Use ODBC, OLEDB, and other methods to extract SQL data from Oracle, most of them are implemented through transparent gateways. In the process of heterogeneous data extraction, it is best to use the SQL92 standard syntax to write SQL code, and pay attention to the Conversion Relationship between data types between dif
