CWWKB0101I CICS unable to connect to angel process after upgrading to z/OS 2.3

Question & Answer


Question

I upgraded to z/OS V2.3 and have the angel process started, but CICS cannot connect to it and as a result Liberty throws the following errors:

CWWKB0101I: The angel process is not available. No authorized service
CWWKB0104I: Authorized service group KERNEL is not available.
CWWKB0104I: Authorized service group LOCALCOM is not available.
CWWKB0104I: Authorized service group PRODMGR is not available.
CWWKB0104I: Authorized service group SAFCRED is not available.
CWWKB0104I: Authorized service group TXRRS is not available.
CWWKB0104I: Authorized service group WOLA is not available.
CWWKB0104I: Authorized service group ZOSAIO is not available.
CWWKB0104I: Authorized service group ZOSDUMP is not available.
CWWKB0104I: Authorized service group ZOSWLM is not available.
CWWKB0104I: Authorized service group CLIENT.WOLA is not available.

I checked security and there are no errors.

Answer

The reason CICS is unable to connect to the Angel process is most likely caused by a mismatch in Angel versions. For example, the version that is running is not compatible with the CICS Liberty code. This problem can be avoided in CICS by using a named Angel that runs the Angel code shipped by CICS and having the CICS Liberty JVMs connect to that specific Angel process.

See the Named angel section in the WebSphere Application Server for z/OS Liberty documentation which discusses how to name an Angel process by coding the NAME parameter on the START command.

See Specifying Liberty bootstrap properties which discusses how to point a JVMSERVER to a specific named Angel server by coding the following property: com.ibm.ws.zos.core.angelName=named_angel
