is in use all the time I am wondering the best practice to replace it..

The strategy I use is to embed the following in TACLLOCL:
PURGE [default_subvol].ZZSEGF*  == Get rid of any old segment files
which are no longer in use.
IF NOT file exists [default_subvol].SYSSEG
OR modif timestamp of [default_subvol].SYSSEG < modif timestamp of
[standard_location].SYSSEG
  ==  SYSSEG does not exist or is out of date
  rename  [default_subvol].SYSSEG,  [default_subvol].ZZSEGFxx  ==
Where xx is unique
  FUP DUP [standard_location].SYSSEG , [default_subvol].SYSSEG ,
SOURCEDATE
ENDIF
ATTACHSEG [default_subvol].SYSSEG == etc

Thanks Doug and Warren.

It seems both have referenced the same as the best solution, but
Warren - I really like your concept of the automation of the task.  I
am thinking that is the route we will take.

I have been doing applications work using COBOL for the past 15 years
and have just started more on the Systems side and working with TACL
and in that regard, these groups have been a real blessing.  Thanks to
all of you who hang out here and help - if nobody has said it enough -
you are extremely appreciated!- Hide quoted text -

One last question on this hopefully. How do you handle the security
on this? Currently we have this secured 255,255, "AGAG"

I could secure it "AAAA" but that kinda defeats the security of the
file and anything else blows up during the rename with error 48.

Thanks in advance for the assistance
.
