Hi All,

I have query regarding Migration of Cobol applications from zOS to Linux on zOS. I have got some documents regarding this issue but didn't get the documents on application impacts when cobol application migrating from zOS to Linux on zOS.


Thanks,
Tushar

zOS to Linux on zOS.

in IT terminology is important ..
there is no Lunux on zOS
in an LPAR You can ipl zOS or Linux.

maybe You meant unix system services

as a general concern while the computing part of the COBOL program will not need any revision
You will have to carry on quite a bit of work for the I/O side

- probably little for the sequential and SQL, but VSAM is not supported
- quite a bit more work for the JCL to be converted to SHELL scripts

Are you developing on z/OS for a target on USS? Or actually "migrating" your systems?

Hi,
Thanks a lot enrico and Bill for your response.... I am sorry for the late reply...

I am looking at finding implementation approach for migrating our z/OS applications (Cobol, JCL, DB2, CICS et al) to linux on system Z. However, I could not find any comprehensive documentation or documented approach for the same. It will be great help if you can point to the same.......


Regards
TG
