Duplicate rpm packages s390 - s390x, can one of them be removed?
We have several Red Hat servers that were set up by our Unix group when we started into the zLinux world. All these servers are running in 64 bit architecture. As I am getting to know they systems better, I did a search on the packages we have installed and found about 71 packages that have both a s390 (32 bit) and s390x (64 bit) versions installed. Is there any reason to have both architectures install for the same package? We just did a basic install of RHEL on one of our test systems, and when I searched that platform, we had no 32 bit packages (great!). Has anyone had similar experience or have any recommendations. I am considering removing all the 32 bit packages from the system, but want to insure that it has no impact on the system. Is there any need for a 64 bit application to have access to it's 32 bit conterpart?

Check the contents of each package. If the package supplies libraries, then DO NOT remove them because other things may depend on them. If the package supplies commands, you may have difficulty removing. (But re-install of preferred arch may suffice.) In the case of libraries, it is normal to have both architectures installed. Desirable even. So ... again ... check what is supplied, and if they are libs, don't sweat it. -- R; Rick Troth Velocity Software http://www.velocitysoftware.com/ On Tue, Sep 20, 2011 at 10:01, CHAPLIN, JAMES (CTR) james.chap...@associates.dhs.gov wrote: We have several Red Hat servers that were set up by our Unix group when we started into the zLinux world.

If a file is not needed, or useful, it has no business clogging up a filesystem and dynamic linker search path (slowing the machine carrying around the non-used parasite) I have removed the non s390x 'multi-lib' packages, under the guidance of rpm, which 'knows' from its use of ldd, and other tools, which are 'safe' to remove, with no ill effects -- Russ herrold -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For more information on Linux on System z, visit http://wiki.linuxvm.org/
Re: Duplicate rpm packages s390 - s390x, can one of them be removed?
Good point, Russ, but presumes that legitimate executables will only be under the purview of RPM. That may be the preferred policy, but is not universal. (And questionable if it really agrees with Unix philosophy, but we're drifting into theory ... history ... opinion.) So if a (legitimate) program requiring 32-bit support suddenly appears (outside registration with the Department of Homeland RPMs) what will it do since you have removed the 32-bit libs?? Clean is good. (get rid of unused libraries) Inventory is good. (track it all with RPM ... or something!) I'm only saying that YMMV. -- R; Rick Troth Velocity Software http://www.velocitysoftware.com/ On Tue, Sep 20, 2011 at 12:14, R P Herrold herr...@owlriver.com wrote: On Tue, 20 Sep 2011, Richard Troth wrote: In the case of libraries, it is normal to have both architectures installed.
