在刚刚安装了 IBM Infosphere 版本 8 的新 unix 服务器上运行 ksh 脚本时,我遇到了 SIGSEGV 错误。当 unix 脚本更新配置文件中的提取日期时间时,我收到错误消息。该脚本由 Datastage 序列调用。
脚本因以下问题中止:“程序“/bin/sh”终止。[SIGSEGV] 分段违规”。
对该问题的网络搜索表明该问题是由对内存的无效引用引起的。
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'"
这是脚本的内容 -

这是我们正在尝试更新的文件(MEARS MSDS_MP_EVENTS_BS_VW Lastupdseqno)的内容 -
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
请帮忙!
