other is in the same state of the last contact. If it is, you can see the message shown in

Example 4-10.

Example 4-10 Syslog for a successful exchange log name between two APPC LUs

ATB207I EXCHANGE LOG NAME PROCESSING HAS COMPLETED SUCCESSFULLY

BETWEEN LOCAL LU USIBMSC.SCSIM8HA AND PARTNER LU

USIBMSC.SCSIM8I$.

PARTNER LOG: ATR.BA04D30D06ADBE08.IBM

There’s a message for each system owning the LU. If there is a failure, depending on the

reason, you can have one or more of the messages shown in Example 4-11.

Example 4-11 Syslog for unsuccessful exchange log name between APPC LUs

ATB227I LOCAL LU USIBMSC.SCSIM8IA IS WARM STARTING AS A RESOURCE

MANAGER WITH RRS/MVS.

+ATB70042I APPC/MVS cannot schedule allocate request. LU SCSIM8IA

can not process syncpt conversations.

In Example 4-11, the ATB225I message shows an APPC problem encountered during an

RRS call, while ATB70042I is a message that APPC sends only to the TP program. Basically

you can have three level of problems, shown in increasing level of severity:

򐂰 Unit of recovery problems, single or multiple

򐂰 LUs warm/cold or name mismatch problems

򐂰 RRS or Logger problems

4.2.1 Solving unit of recovery problems

This is the lowest severity problem. Some information is available in RRS's logs because of a

missed or failed resynch process after a UOR failure. You have to remove the interest of

APPC for this UOR using the RRS panels. Example 4-12 shows a sample of RRS UORs.
