I have a SLES10 server that is running a java app using tomcat5 and is
hitting out of memory conditions.
I bumped up the virtual storage in the VM directory and found the out of
memory problem went away.
Now I want to bump the virtual storage back down but instead increase
the size of the V-disks being used for SWAP. I saw that this server had
4 V-DISK MDISK statements. I increased each of the 4 minidisks from
200000 blks to 600000 blks:
MDISK 0293 FB-512 V-DISK 600000 MR LINUX SWAPAREA DASDDA
MDISK 050D FB-512 V-DISK 600000 MR LINUX SWAPAREA DASDDA
MDISK 050C FB-512 V-DISK 600000 MR LINUX SWAPAREA DASDDA
MDISK 050B FB-512 V-DISK 600000 MR LINUX SWAPAREA DASDDA
I also found the swap disks get formatted in the PROFILE EXEC:
For example:
queue '1'
queue 'LXSWAP'
'FORMAT 293 E ( BLK 512 '
if rc <> 0 then exit rc
I rebooted the server (test server that I can reboot as needed).
cat /proc/dasd/devices does show the size increase
For example:
0.0.050b(FBA ) at ( 94: 228) is dasdbf : active at blocksize:
512, 600000 blocks, 292 MB
What do I need to do on the SLES10 server to get it to use the V-DISK's
for swap and is there a command to query swap in use?
