Hi Rob,
Thank you for your response.
Of course, I know that The PERMIT ... WHEN( ) operand is not on the time/date for general resources.
But I believe that the PERMIT ... WHEN( ) operand must set requirements on the environment of the resource access, on the time/date too.
I think it is a very important need to be able to use the PERMIT ... WHEN() operand with time/date. Over the years, the need for the RACF's functionality has improved. RACF must be improved by our suggestions. While there are extraordinary developments in the field of cyber security, we expect some developments in the RACF too. This is only my improving suggestion as a customer. I hope IBM will evaluate this recommendation.
Regards,
Kayhan Tanrıverir

Subject: Use RACF PERMIT command with conditional access list
Hello Kayhan.
The PERMIT ... WHEN( ) operand is meant to set requirements on the environment of the resource access, not on the time/date. You can require that updates to critical data sets are only permitted from a specific program.
The ALTUSER WHEN( ) operand is meant to limit the time/days when a logon can occur. There is a DAYS but no DATE specification.
The two use the same WHEN( ) but for different domains.

Subject: Use RACF PERMIT command with conditional access list
Hello,
I want to use the PERMIT command with a conditional access list using the WHEN clause, but the WHEN clause has very limited options.
As you know, the TCPIP OBEYFILE command is very critical, I want to limit the use of this command, especially during working hours (shift).
I imagined using the PERMIT command with the WHEN clause as follows,
PERMIT MVS.VARY.TCPIP.OBEYFILE ACCESS(CONTROL) CLASS(OPERCMDS) ID(USER1) WHEN(NOT (DATE(*-01) OR DATE(*-15)) AND TIME(08:00-18:00))
According to this command format, the TCPIP OBEYFILE command will not be used on the 01, or 15 dates of the month and also it will not be used at working hours.
I know that this usage of the PERMIT command is not in the RACF. How can I use this command format in the RACF?
