We are currently running zVM 5.4, zLinux Redhat 5.4 with DB2 installed zLinux is defined with 6Gb of memory in it's directory. The zVM Lpar is
defined with 10GB of memory. When DB2 is brought down (within zLinux) th e display (within zLinux) still shows memory still allocated as the display below shows: ----------------- top - 18:01:01 up 5:54, 8 users, load average: 0.04, 0.28, 0.66 Tasks: 117 total, 2 running, 115 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 6174360k total, 5620744k used, 553616k free, 32952k buffers Swap: 4464032k total, 200k used, 4463832k free, 5395900k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND ----------------- The memory was finally released after 30 minutes. I am not well versed i n Linux but more of a Vm person. But my questions are: 1. Is this normal? 2. What is holding the memory for 30 minutes? 3. Can the memory be released as soon as DB2 is brought down? 4. Is there a parm somewhere to tell DB2 or zLinux to release that memory ? Any assistance would greatly be appreciated. Thanks. Steve
