Change the security of connection definitions on the mainframe host by doing the following:

1. Expand the group that contains the connection definitions. For example: CEDA EX GR(MYCONNGRP)

   Replace MYCONNGRP with the name of the group that contains your connection definitions.

2. Alter security of each connection definition by changing the value of ATTACHSEC to VERIFYon each connection definition.
3. Put each connection out of service by inquiring on the connection’s CEMT I CONN(MYCN) and tabbing to the connection, then changing the INS entry to OUT.
4. Install the modified connection definitions. For example: CEDA I GR(MYCONNGRP)

   Replace MYCONNGRP with the name of the group that contains your connection definitions.

5. The security definition is complete. Run the application.
