Consoles and Migration ID Exits › Number of Consoles › Considerations

Considerations

If a region requires a large number of consoles, then the larger the number of consoles retained, the more efficient the region becomes. However, retained consoles are not available to other applications.

Consider the following when specifying the Max Consoles to Retain value in the CONSOLES parameter group:

• The number of MSP OP1 and OP2 consoles is limited to 10 per system.
• The number of z/OS JES consoles is limited to 99 across a sysplex.
• It might be necessary to limit the number of consoles to retain if a significant number of extended MCS consoles require migration IDs.
