IOSHC101E
Captured UCB overlay protection is expected to be expect but is actually actual.

Explanation

CHECK(IBMIOS,IOS_CAPTUCB_PROTECT) determined the current captured UCB protection is not in its expected state of expect. When enabled, captured UCB protection obtains captured Unit Control Blocks in protected storage and prevents storage overlays. However, there may be rare issues with software.

In the message text:
expect
Captured UCB protection desired state (enabled or disabled)
actual
Captured UCB protection current state (enabled or disabled)

System action

The system continues processing.

Operator response

Please report this problem to the system programmer.

System programmer response

If the state of captured UCB protection should be enabled, issue this command from the system console: SETIOS CAPTUCB,PROTECT=YES

Also, in the IECIOSxx member, if the following line exists then remove it: CAPTUCB PROTECT=NO

If the state of captured UCB protection should be disabled, issue this command from the system console: SETIOS CAPTUCB,PROTECT=NO

Also, in the IECIOSxx member replace: CAPTUCB PROTECT=YES with CAPTUCB PROTECT=NO.

Alternatively, update the expected captured UCB protection state to be consistent with the current captured UCB protection state by supplying a check parameter of PROTECT(YES) or PROTECT(NO). Then, rerun this Health Check.
