KornShell SQL脚本解析器 - 来自ksh的并行执行

I am trying to run bunch of scripts in parallel in KornShell (ksh) co-processes. Some of these scripts contain many DDL statements. Those DDL statements are identified to be independent and work against different (and large/expensive eg: 35 million rows and above) database objects. In order to run them in parallel, I am considering to create separate sub-scripts with each DDL statement - so that I can say: SQL*Plus - that is going to be many :( -- resulting too many read and write -- because it is a batch process, time required is not too critical but (may still lead to thrashing in this single disk-parallel execution environment)..I am trying to run bunch of scripts in parallel
