This section provides information on moving OAM from one OAM system
to another OAM system, neither of which is part
of an OAMplex. To merge OAMs into an OAMplex, perform the procedure
in Merging OAMs into an OAMplex.
The following steps are necessary when moving the entire OAM application
from one single system to another single system. These steps can be
followed after the installation and migration steps have been completed,
should you need to move OAM from one system to another.
- Install OAM and DB2 on system SYS2 by following the procedures
in High-level installation and migration checklists.
_______________________________________________________
- Make copies of the OAM DB2 databases from system SYS1 using DB2
utilities. The OAM DB2 databases are the Object Storage Databases,
Object Administration Database, and the OAM Configuration Database
described in Understanding OAM databases.
_______________________________________________________
- Copy the Integrated Catalog Facility (ICF) catalog where the collections
reside from system SYS1 using the Export function of Access Method
Services (IDCAMS). For more information on this Export function, see z/OS DFSMS Access Method Services Commands.
_______________________________________________________
- Start DB2 on system SYS2.
_______________________________________________________
- Move the copies of the OAM DB2 databases to system SYS2 using
DB2 utilities.
_______________________________________________________
- Move the copies of the collection definitions to the Integrated
Catalog Facility (ICF) on system SYS2 using the Import function of
Access Method Services (IDCAMS).
_______________________________________________________
- Delete all of the optical library and drive definitions from system
SYS1 using the ISMF Optical Library Application.
_______________________________________________________
- If system SYS2 is not defined in the SCDS, then from system SYS1
add it as a valid system under the Control Data Set Definition Application
of ISMF.
_______________________________________________________
- Move the SCDS from system SYS1 to system SYS2 by using the copy
function of DFSMSdss. This only needs to be done
if system SYS2 is not part of the same complex that is sharing the
SMS SCDS.
_______________________________________________________
- Using the ISMF Storage Group Application on system SYS2, alter
the Object and Object Backup storage group definitions to change the
connectivity of SYS1 to not connected and the connectivity of system
SYS2 to enabled.
_______________________________________________________
- Using the ISMF Optical Library Application on system SYS2, alter
the library definitions connectivity from system SYS1 to system SYS2.
This is only applicable for the controlling libraries. Altering these
models automatically alters any connected library expansion units
associated with the controlling libraries.
Tip: You
might need to delete and redefine all the 3995 operator-accessible
drives.
_______________________________________________________
- Using the ISMF Optical Library Application on system SYS2, redefine
all of the library definitions. Using the ISMF Optical Drive Application
on system SYS2, redefine all of the drive definitions associated with
the libraries. If the definitions do not exist in the DB2 OAM configuration
database tables, they are added, but if they do exist, the information
is updated in the DB2 tables. The information is added to the SCDS.
_______________________________________________________
- Activate this SCDS from system SYS2. Activation might be done
from the operator console by using the SETSMS SCDS (source control
data set name) command or by using the Activate Configuration option
of ISMF.
_______________________________________________________
- Start OAM.
