在刚刚安装IBM Infosphere版本8的新unix服务器中运行ksh脚本时,我正面临SIGSEGV错误。 我在unix脚本更新配置文件中的提取日期时出现错误。该脚本由Datastage序列调用。来自unix ksh脚本的分段错误
该脚本中止问题: “Program”/ bin/sh“已终止。[SIGSEGV]分段违例”。
该问题的网络搜索表示问题是由无效的内存引用引起的。
下面提到的是执行脚本的命令。
"ksh shUpdate_Config.sh MEARS MSDS_MP_ATTRIBUTES_BS_VW /data/projects/scver_etl/EXTRACTS_pub/configurationfiles/MEARS.MSDS_MP_ATTRIBUTES_BS_VW.Lastupdseqno.dat /data/projects/scver_etl/EXTRACTS_pub/configurationfiles/ '2012-08-08 12:35:24'"
这里是脚本的内容 -

下面是该文件的内容(MEARS MSDS_MP_EVENTS_BS_VW Lastupdseqno),我们正在努力更新 -
Source_sys_name|Source_tbl_name|Seq_No|Extraction_date|Extraction_Mode
MEARS|MSDS_MP_EVENTS_BS_VW|37|2012-08-08 11:51:19|D
请帮助!
当你运行/ bin/ksh时,它真的说“/ bin/sh terminated”吗?它死在哪里('ksh -x script ....'显示为最后几行)? – twalberg
