Has anyone migrated a DB2 database from z/OS to Linux on z where the
application code was written in assembler? I am wondering if it is
possible to use the z/OS precompiler output with the DB2 database set up
on Linux on z? If this is not possible, what other alternatives have you
looked at?
Hi Jeff,
You can use the Dignus assembler to assemble things in HLASM
format and directly create a z/Linux ELF object ... and even be able
to debug it (at the ASM source level) with gdb, etc... The Dignus
tools write out extra debugging information for that.
You would, of couse, need to
z/OS assembler code will have to be rewritten.
Linux/z is usually ASCII, not EBCDIC. Think about all those CLC's.
If you start by rewriting the assembler code in C and go through the SQL to
find all the cases where LUW and DB2/Z disagree, your only remaining problem is
whither the JCL.

I, once, ran across some "use at your own risk" steps to change the SSI cluster
name of a z/VM system. I can't seem to locate them now. Does anyone know how
to do this?
Steps I do know.
Change OWNER info for those volume that have SSI specified..(spool, page...)
Update SYSTEM CONFIG file
Troy,
You'll probably need to run FORMSSI to rebuild the PDR.
You'll need the whole cluster down to rebuild the PDR. Either bring one member
up in REPAIR mode to make the change, or access the PDR volume from a system
that is outside of the cluster. I expect that changing the SSI name in
There is a package on the IBM VM download "RENSSI" that you might want to
take a look at. It's purpose is not to change the cluster names but to
change member names. There may be some useful information there.
