This section provides information on adding OAM systems to an existing
OAMplex. When you initialize OAM, it looks for the OAMXCF statement
in the CBROAMxx PARMLIB member. If the OAMXCF statement exists, this
OAM system joins the XCF group, which means that it joins the OAMplex.
Each OAM system in the OAMplex share the DB2 databases (object storage
and OAM configuration databases).
- Update the IGDSMSxx PARMLIB member for each OAM system
that you are adding to the OAMplex. For more information, see 5 Changing system libraries.
- Add the DB2SSID parameter to the IGDSMSxx PARMLIB member.
The DB2SSID parameter specifies the name of the DB2 system.
- Add the OAMPROC and OAMTASK parameters to IGDSMSxx only
if you need to start the OAM address space to initialize SMS on the
new system.
- Issue the SET=SMSxx command to update the SMS information.
_______________________________________________________
- Update the CBROAMxx PARMLIB member to include the ONLYIF
statement to specify whether or not specific statements, within the
CBROAMxx, are to be processed on a given system.

_______________________________________________________
- Update the OAMXCF statement in the CBROAMxx PARMLIB member
to include the XCF group name and OAM member name for each OAM system
that you are adding to the OAMplex. Each OAM system has a unique OAMMEMBERNAME
and belongs to the same OAMGROUPNAME. For more information, see OAMXCF statements in an OAMplex.

_______________________________________________________
- Set up an OAM PROC with the OAM=xx parameter for the
new system, where xx is the low-order suffix of your CBROAMxx PARMLIB member. For more information, see step 5h2 in 5h Updating the PROCLIB.
_______________________________________________________
- Set the OSMC processing system to the desired system for each
Object and Object Backup storage group.
_______________________________________________________
- Update all the Object and Object Backup storage groups so that
they are enabled to each system where OAM is running. For more information,
see Defining storage groups and relating the libraries to the storage groups.
_______________________________________________________
- Ensure that the DB2 tables are in a data sharing group. Contact
your DB2 administrator to set up the data sharing group.
_______________________________________________________
- If applications connect to DB2 and call OAM, the DB2SSID and the
data sharing group that they connect to must be the same, or else
the "Connects to two DB2s from one TCB" error displays. Contact
your DB2 administrator for assistance with this step.
_______________________________________________________
- Run the CBRSMERG and CBRS100 jobs to merge the OAMs into the OAMplex
at this point. For more information, see Merging OAMs into an OAMplex.
_______________________________________________________
- Start OAM on each system in the OAMplex. Display the DISPLAY
SMS,OAMXCF command on each system to verify that they joined
the OAMplex successfully.
_______________________________________________________
Result: Now all of the OAM systems belong
to the OAMplex.
