To determine which tables in a database have page-level locking and need to be modified to row-level locking, I use a helpful SQL script: genlockmod.sql (see Listing 1).
为了确定数据库中的哪些表具有页面级锁定以及需要修改为行级别锁定，我使用了一段sql脚本：genlockmod . sql(参见清单1)。
This script will read the Informix system tables, find out which tables have page-level locking, and then generate another SQL script to change those tables to row-level locking.
此脚本将读取Informix系统表，找出哪些表具有页面级锁定，然后生成另一段sql脚本来将这些表更改为行级别锁定。
