GLYPH<SM590000> The journaling statement of z/VM allows the CP to control two kinds of actions: LOGON  and LINK . The LOGON  parameter starts on line 4 of Example 5-20 on page 131 and the LINK parameter starts on line 9 of the same example. Although the parameter is called LOGON , it also tracks successive tentatives of AUTOLOG and XAUTOLOG with an incorrect password in addition to the LOGON  command. 

For both parameters, it is possible to configure two options: MESSAGE  and ACCOUNT . The MESSAGE  parameter sets up the number of possible tries before a user receives an information message. Although any user can be set to receive the information message, setting a user that has the console logged is preferred as it is possible to look for the information later after the event happened. 

In Example 5-22, user EDI tries to log on repeatedly with an incorrect password. The MESSAGE parameter was set to user BOB. 

#Logon tried repeatedly, but just one output is shown: l edi ENTER PASSWORD (IT WILL NOT APPEAR WHEN TYPED): HCPLGA050E LOGON unsuccessful--incorrect password Enter one of the following commands: LOGON userid (Example: LOGON VMUSER1) DIAL userid (Example: DIAL VMUSER2) MSG userid message (Example: MSG VMUSER2 GOOD MORNING) LOGOFF #After third try, user bob receives the information message: HCPJRL145I User EDI at 9.12.5.143 issued a LOGON command with an invalid password 003 times. The limit is 003. 

The same happens with successive LINK  command attempts with an incorrect password to access a protected minidisk. Example 5-23 shows user EDI trying to link to the 191 protected minidisk of user BOB with an incorrect password.
