Re: Question on MongoDB usage under z/VM

I've been asked by my management if we can support MongoDB (with SOLR) using RHEL under z/VM. Has anyone on this list given this a try? Inquiring minds would like to know what your thoughts are. It builds and runs cleanly (there's no s390x RPM AFAIK, but the source RPM builds without

Re: Question on MongoDB usage under z/VM

AFAIK MongoDB (the server side) still support only little endian architectures, so no luck with s390 (or ppc) unfortunately. Recent updates have removed most of those restrictions.

Re: Question on MongoDB usage under z/VM

2013-01-04 Thread David Boyes
The MongoDB server (mongod) must run on a little-endian CPU, so if you are using a PPC OS X machine, mongod will not work. So it's not true anymore? Doesn't seem to be if you have the most recent SRPM. They've been doing a lot of work to remove some of those limitations in recent versions,

SWAPGEN is a CMS application, so you can't use it when Linux is running, however, you can temporarily define and format a new VDISK with DEFINE (via vmcp) and the Linux commands, add it to fstab, and then update the PROFILE EXEC to add the SWAPGEN line to define the temporary addition as a

The last time I looked, CentOS for s390 was really old: 4.4 I think, where Intel is now at 6.3. 6.2 and 6.3 will be available shortly. We have a few issues to work out with signing the packages to prevent tampering, but not long now.

I didn't think you could take a Linux that wasn't written specifically for system z and run it. Given that NGINX is just an application program that can be compiled on any Unix-like system, it runs fine when built from source on Linux on Z. The NGINX www site does not supply System z

Yeah - we'll probably start small, with say half a GB cache and see if it affects other packages. We use VDISk for paging, and perfmon shows that we have XSTOR, but no usage. Well, that's probably a good sign of plenty of resources to play with. I wonder if it would help to put nginx,

But our Z enthusiast says we can put Redis and memcache on Z-Linux (under VM) without any loss of functionality or performance (because we have extra capacity and paging on Z doesn't cost anything). I'd agree on functionality, but performance is a harder question. Both redis and memcache

This smells like the last argument we recently had on this topic. udevadm settle is not always reliable and the last response was that you have to sit and poll until the device actually appears before continuing. Broken, IMHO, but apparently WAD. On Oct 18, 2012, at 14:36, Michael MacIsaac

Can't test this at the moment, but do the system logs tell you if the relocation generates a disconnect/reconnect event for the interface in question? IMHO, if it doesn't, then it should, since you're doing the equivalent of unplugging the machine, moving it, and then reconnecting it. Even if
