We are testing DR for an OS/390 2.10 system with IMS.
Before the backups, CICSs are shut down and /DBR DB ALL is issued. We
then copy all disk volumes to tape to send to the DR site.
When we restore the system to the DR box, sometimes we have to issue the
/ERESTART OVERRIDE command to get IMS happy. Sometimes IMS is happy
without the /ERESTART.
My main systems programmer says 'We are doing it the way we always
have.' I am wondering if there is something else we should be doing.
[We can't flash as OS/390 2.10 does not talk correctly with flashcopy on
the DS8300 we are using. A flash command turns into a standard disk copy.]
