Description:
I was wondering if Ex Libris has any policy or best practices recommendation on how many Service Pack versions back new executables should be kept.

For instance, I see that we have a version of z39 in /exlibris/aleph/a18_1/alephm/source for each version of the Service Pack we've installed:

20052 z39
36200 z39.sp.1002
36204 z39.sp.1222
35212 z39.sp.1323
38664 z39.sp.662
36528 z39.sp.925

and there are older versions of lots of files in /exlibris/aleph/a18_1/aleph/exe. At what point can some of those be removed? Are there recommendations or cleanup routines that I should be running to address these? Because, over time, they take up a lot of space.

Resolution:
There are no scripts, routines or recommendations on Service Pack cleanup.

In the case of executables, you need to keep only the files for the Service Pack preceding the current one.

These commands could be used to delete the others:

ae [this takes you to ./aleph/exe ]

rm *sp.662
rm *sp.925
rm *sp.1002
rm *sp.1222

Since the sp.1323 is the sp preceding the current one, you should leave that.

The source files are different. We may need to look at older files in analyzing problems. We ask that you not delete any ./alephm/source/ files, $aleph_proc files, etc.
