Use the MVS START command to start the OAM address space manually or to restart the OAM address space after it has terminated. The syntax of the MVS START command that is used to start OAM follows:

>>-+-START-+--+-OAM------+--+-------------+--+---------+-------->
   '-S-----'  '-procname-'  '-.identifier-'  '-,OAM=xx-'   

>--+----------------+--+---------------+-----------------------><
   '-,REST=-+-NO--+-'  '-,REUSASID=YES-'   
            '-YES-'                        

OAM

Name of the IBM-supplied cataloged procedure that invokes OAM.

procname

Name of the user-written cataloged procedure that invokes OAM.

identifier

User-determined name that identifies the OAM address space. If you do not specify an identifier, the system automatically uses the procname as the identifier.

OAM=xx

OAM=xx specifies the suffix of the CBROAMxx PARMLIB member that OAM should process during OAM address space initialization. The two alphanumeric characters (xx) must immediately follow the OAM= keyword in the PARM field. OAM reads PARMLIB member CBROAMxx only if the OAM= keyword is specified on the PARM field of the JCL EXEC statement in the OAM cataloged procedure. OAM processes PARMLIB member CBROAMxx during OAM address space initialization and for tape library processing is used for the optional SETTLIB support.

REST

Determines whether OAM should automatically restart when it receives notification that a new SCDS is activated. The valid values for this parameter are:

NO

OAM does not automatically restart when a new SCDS is activated.

YES

OAM automatically restarts when a new SCDS is activated.

REUSASID=YES

REUSASID=YES can be specified to allow OAM address space to be reused should OAM be stopped. This parameter should only be used with OAM's tape library support and should not be specified if OAM is also being used for object support.

When OAM is initialized, the system issues the following messages:

CBR0001I  OAM initialization starting.
 
CBR0002I  OAM initialization completed.

If other CBRxxxxx messages are issued, see z/OS MVS System Messages, Vol 4 (CBD-DMO) for the appropriate action to take.
