您可以创建一个键控逻辑文件或 SQL 索引,它们共享物理文件的索引。
You can create a keyed logical file or an SQL index that shares the index of the physical file.
可以为 DDS 创建的连接逻辑文件创建多个索引。
Multiple indexes may be created for a DDS-created join logical file.
在 IDS 中,始终以循环的方式使用逻辑文件。
In IDS, logical files are always used in circular fashion.
如果只对逻辑文件进行恢复,需要使用 -l 选项。
To restore only the logical files, the -l option can be used.
例如,对保存在 SQL 索引或键控(keyed)逻辑文件中的键值执行随机的键查找操作。
For example, random key look-up operations against the key values stored in an SQL index or keyed logical file.
现在,您可以对新的逻辑文件或SQL索引发出CHGLFM 命令,将索引移入或移出SSD,而数据保持不动
Then you can issue CHGLFM against the new logical file or SQL index to move the index on or off of SSD and the data will not be moved
处理以上所有情形的方法是创建一个简单的键控逻辑文件或SQL索引,它们共享您希望放在SSD 上的索引(或访问路径)。
The way to handle each of these cases is to create simple keyed logical files or SQL indexes that share the index (or access path) you want on an SSD.
愿你脑中的逻辑文件都被一个叫做“爱”的程序故障破坏掉。
May the files of logic be corrupted in your brain by a bug called LOVE.
