9. Set the PERFSVM virtual machine to be started at z/VM IPL time. Edit the PROFILE EXEC
file on AUTOLOG1 so that PERFSVM is automatically started at IPL time. First, log on to
AUTOLOG1.
10.Before pressing Enter at the VM READ prompt, type acc (noprof so that the PROFILE EXEC
file is not run:
LOGON AUTOLOG1
z/VM Version 6 Release 1.0, Service Level 1002 (64-bit),
built on IBM Virtualization Technology
There is no logmsg data
FILES: NO RDR, NO PRT, NO PUN
LOGON AT 14:51:02 EDT THURSDAY 10/07/10
DMSIND2015W Unable to access the Y-disk. Filemode Y (19E) not accessed
z/VM V6.1.0 2010-09-23 11:31
==> acc (noprof
11.Add a line so the virtual machine PERFSVM is started at z/VM IPL time:
==> x profile exec
/***************************/
/* Autolog1 Profile Exec */
/***************************/
'cp xautolog tcpip' /* start up TCPIP */
'CP XAUTOLOG VMSERVS'
'CP XAUTOLOG VMSERVU'
'CP XAUTOLOG VMSERVR'
'CP XAUTOLOG DTCVSW1'
'CP XAUTOLOG DTCVSW2'
'cp xautolog perfsvm' /* start Performance Toolkit */
'cp set pf12 ret' /* set the retrieve key */
...
12.Save the file and log off from AUTOLOG1.
14.2.4 Increasing the size of the MONDCSS DCSS
The Discontiguous Shared Segments (DCSS) named MONDCSS shipped with z/VM V6.1 is
often not large enough, especially when your LPAR has access to many devices. To increase
the size of the DCSS, first determine where the current MONDCSS is located by entering the
following command:
==> q nss name mondcss map
FILE FILENAME FILETYPE MINSIZE BEGPAG ENDPAG TYPE CL #USERS PARMREGS VMGROUP
0011 MONDCSS CPDCSS N/A 09000 09FFF SC R 00001 N/A N/A
In this example, the DCSS starts at x9000 and ends at x9FFF. This is x1000 or 4096 pages.
Because a page is 4096 bytes or 4 KB, the size of this DCSS is 16 MB (4 KB * 4 KB).
