Hi list, We have 2 lpars in sysplex,one is for production,the other is for development,both are in zos1.9. Recently we noticed the smf datasets' size have huge difference, and we found the main reason is the type 30 record length is different.Any idea of the reasons? below is one sample from SMFDUMP output.
