We then installed this CONNECTION template using the command:
CEDA INS GR(PJA4AI62)
SYSID=PJA4 APPLID=SCSCPJA4
Important: For an autoinstall connection to be successful, you must also set
the autoinstall program to be DFHZATDY. For further details refer to 2.2.3,
“CICS connection autoinstall” on page 23.
Link security
Next we decided to disable link security. Link security is an additional level of
security that applies to all attach requests received over a connection. For APPC
requests such as TCP62, this is set as follows.
The SESSIONS definition is checked as follows:
1. The SESSIONS definition is checked. If the USERID parameter is specified,
this is used as the link user ID and no further checks are made.
2. The CONNECTION definition is checked, and the SECURITYNAME specified
here is used as the link user ID.
3. If all else fails, the CICS default user ID will be used.
