While at a Year 2000 session, I raised the question of having the
programs able to read archived data. One participant claimed that the
legal requirement was only to have the data and that there was no
requirement to be able to read it.
Interesting approach <g>. In fact it could be "legislative hole",
because the intent is obvious: the data is kept to have possibility of
reading it.
BTW: that's why regular backup usually cannot be archive copy - maybe
few versions ahead tool won't be able to read it. If it will be able,
then maybe the application won't be able to access old data format. And
the old version of application cannot run on current system. And the old
system cannot work on current hardware. Sometimes as "the least common
denominator" (or simply most popular format) is TXT file.
Example: OS/390 2.6, DB2 V4. I can read the tapes with backup (still
have tape drives), likely (I'm not sure) my current DFHSM will read the
backups, but - will DB2 v9 read imagecopies (or tablespace dump) from
DB2 v4 ? Will DB2 v4 run on z/OS 1.10 ? Will OS/390 2.6 run on z10 ?
And this is only approx. 10 years on the best platform in terms of
compatibility.
