Accessing your databases

You can access an IMS database in one of two ways: either under the control of an IMS Control Region (BMP mode); or as a batch process executing as its own IMS subsystem (DLI mode). For both modes, you have the option of using a dynamic PSB or a static PSB.

The concepts and tasks described in this section are:

• About the different access modes
• Accessing in BMP mode using a Static PSB
• Accessing in BMP mode using a Dynamic PSB
• Accessing in DLI mode using a Static PSB
• Accessing in DLI mode using a Dynamic PSB
