IDC3030I CONTROL INTERVAL SIZE TOO LARGE

Explanation
The data component control interval size specified
is greater than 32,768 or the index component control interval size
is greater than the maximum block size of the index device.  See the
associated second-level message for the specific catalog management
error code values.
In the Time Sharing Option/Extensions (TSO/E)
environment the second-level message is not displayed, except by request.
 To request it, enter a question mark (?) after the TSO READY message.

System action
The system ends the command.

Programmer response
Do one of the following: Reduce the control interval size.
If the error occurred due to the index component's device type,
use a different device with a larger blocksize.
