See the help file for v1310 of SWAPGEN... 8-) If you haven't already done so, make sure the VDISK system and per-user limits are set to Infinite in SYSTEM CONFIG and that you have enough VM page space to back the demand. I tried using swapgen to define a 2G (4194304 blks) space and it says

Re: oracle question

Thanks - I ended up having 4 swap disks (1 500M dasd, one 1G vdisk and 2 2G vdisks - total of 5.5G). I just hope that it's enough. Time will tell. Just make sure that the real DASD one is used last by making sure the VDISK ones are prioritied.

Re: Mirroring and recovering LVM volumes

You can also use LVM itself to mirror the data. See man lvcreate for the - m/--mirrors option. Either way, I don't see any reason why you shouldn't use the SVC itself to mirror the disk(s). I'd second this approach. One less thing to deal with in software configuration management.

Re: LVM thin provisioning

SFS pretty much does exactly that -- for CMS users. You can provide access to files stored in SFS for Linux via the CMS NFS server. Not exactly high-performance (dispatching 2 or 3 virtual machines to handle each transaction is kinda heavyweight), but it works. Working on something better.

Re: VMCP commands for non-root userids

Use sudo. I have a non-root UserID that needs to be able to execute VMCP commands. I've tried a lot of things, but it has not yield much success. Any suggestions?? -- For LINUX-390 subscribe / signoff / archive access

Re: Whats the best way to share z/VM Volumes between two Redhat guest machines

If you want both of the servers live at the same time, you need the content volume r/o to both systems, or a cluster file system, or to mount the content from a 3rd machine via NFS. If you're OK with a single point of failure, you can set up one system as a NFS master and then mount the
