Resource Security

You can control access by a transaction to the following types of resource:

• Files
• Transient data queues
• Temporary storage queues
• Journals
• Other transactions

To enable resource security, do the following:

1. Specify that a transaction is to perform resource security checking, by checking Security: Resource Level Checking on the PCT page in ESMAC for the transaction. (By default, transactions do not perform resource security checking.)
2. Specify a set of resource keys in the resource table entry (for example, the FCT entry for a file). Each resource key is a number in the range 1 through 24.
3. Specify a set of resource keys in a user's SNT entry. A user can access a resource if one or more of the resource keys for the resource matches a resource key specified in that user's SNT entry.

The figure below illustrates the process of resource key checking.
