CBR8104I OSR's entry point not found by the load macro.

Explanation
  The OSR-to-CICS interface to this CICS® address space was not completed because
the Operations Service Restructure load module entry point needed
to initialize the CICS Resource
Manager Interface could not be found. This failure is due to an improper
installation of the OSR function of the OAM. The OAM has not initialized
the CICS Resource Manager Interface
and OSREQ macros can not be issued.

System action
 Subsystem processing continues.

Operator response
 Notify the system programmer.

System programmer response
 Check the installation procedure
used to install OAM and particularly the CBRINIT load module that
contains the Operations Service Restructure code.
