You should see a few screens of messages scroll by and finally the success messages
shown above. This will enable the Performance Toolkit for the current z/VM session.
At IPL time, the SYSTEM CONFIG file is modified by having a line appended to the end.
Verify that this has been added by the SERVICE command with the following commands:
==> link * cf1 cf1 rr
==> acc cf1 f
DMSACP723I F (CF1) R/O
==> x system config f
====> bot
====> -2
====> pre off
...
PRODUCT PRODID 6VMPTK10 STATE ENABLED DESCRIPTION '12/17/09.15:35:41.MAINT
PE
RFKIT Minidisk Install and Service'
The Performance Toolkit is now enabled. You can also verify this with the QUERY
PRODUCT command again.
14.2.2 Configuring web browser support
After the product is enabled, the TCPIP profile must be modified to enable web access to the
Performance Toolkit. The following example sets the port to 80, the default for a web browser:
1. Log on to TCPMAINT. Edit the TCPIP configuration file. In this example, it is the
POKSND61 TCPIP D file (assuming you modified this file name earlier; the default name
is PROFILE TCPIP) and search for the string reserve ports. This is where z/VM TCP/IP
ports are reserved.
==> x poksnd61 tcpip d
====> /port
2. Add the following line under the PORT entries:
...
PORT
20 TCP FTPSERVE NOAUTOLOG ; FTP Server
21 TCP FTPSERVE ; FTP Server
23 TCP INTCLIEN ; TELNET Server
; 25 TCP SMTP ; SMTP Server
; 53 TCP NAMESRV ; Domain Name Server
; 53 UDP NAMESRV ; Domain Name Server
; 67 UDP DHCPD ; DHCP Server
; 69 UDP TFTPD ; TFTPD (Trivial FTP) Server
; 69 UDP TFTPD ; TFTPD (Trivial FTP) Server
80 TCP PERFSVM ; Performance Toolkit
; 111 TCP PORTMAP ; Portmap Server
...
Save your changes. The TCPIP user ID needs to be recycled in order for our changes to
take effect. You can FORCE and XAUTOLOG TCPIP from a console. Alternatively, if you
are in a position to perform an IPL of the system, you can do that (run shutdown reipl
iplparms cons=sysc).
