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

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

+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.
