I got the message "Paging space Low" while I was running a program in a background (use &) on RISC/6000 320. Can anyone tell me the procedure to increase the size of the paging space (currently the size is 32 Mb)? And, how much can I set the maximum to? Real memory is 16Mb. Thank you in advance.

To increase the size of your paging space: Become superuser Run "smit" Select "Physical and Logical Storage" Select "Paging Space" Select "Change/show characteristics of a paging space" to modify an existing one, or "Add Another Paging Space" to create another one. Fill in the blanks and press Enter. That's it! Sam Drake / IBM Almaden Research Center Internet: drake@ibm.com BITNET: DRAKE at ALMADEN Usenet: ...!uunet!ibmarc!drake Phone: (408) 927-1861

Increasing pgspace is straight forward with smit .. it tends to be a good idea to use smit for the things it does well. If you have more than one disk, try to spread the increase around to pgspace's on each disk. Real memory size has little to do with how big to size your pgspace... on the high end of its size you want to consider total disk space available. On the low end, you need enough to keep your workload from starving, as you currently are. I tend to increase pgspace on machines in 50% size increments, but I have all the disks I could want. g -- gary a hoffman RISC Systems, Watson Research

Is there a way to reduce a partition's allocation to create unallocated space which can be turned into paging space? We've been taping partitions off, and rebuilding, which isn't as much fun as the very elegant SMIT interface (that's a pat on the back guys!)

Well, then you're talking about a command that doesn't exist "reducelv". There are low level (undocumented!!) commands (lreducelv) but they don't handle odm and you're on your own when you decide which partitions to delete from your filesystem or paging space. Neither of those works for reducing at this time. :-{ Sounds like you are doing the right (painful, I know) procedure to free space on your system. -- *=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= Julie A.

There's currently no simple way to reduce the size of a logical volume. Sam Drake / IBM Almaden Research Center Internet: drake@ibm.com BITNET: DRAKE at ALMADEN Usenet: ...!uunet!ibmarc!drake Phone: (408) 927-1861
