Object Data Manager (ODM)

• What is ODM?
  • Maintains system config, device and vital product data
  • Provide a more robust, secure and sharable resource
  • Provide a reliable object oriented database facility

• Data Managed By ODM:
  • Device Configuration Information
  • Software Vital Product Data
  • SRC information
  • Communications configuration data
  • Menus and commands for SMIT

• ODM has three components
  • Object class – These are datafiles.
  • Objects – Records within Datafiles
  • Descriptors – Field within a record

• Where ODM Object Class files are stored?
  • This can be defined in /etc/environment file. The ODM object clases are held in three repositories

/etc/objrepos
/usr/lib/objrepos
/usr/share/lib/objrepos

• Some important ODM Database files
  • Supported devices and attributes and connection information are stored in

PdDv, PdAt, PdCn, etc..
Records or customizrd Devices and attributes, VPD are stored in
CuDv, CuAt, CuDep, Config_Rules, CuVPD, etc …

• Have software information

lpp, history, product, inventory, etc..
SMIT menus, commands, options
sm_cmd_hdr, sm_cmd_opt, sm_menu_opt
NIM Resource and configuraion information
nim_object, nim_pdattr, nim_altr
Errorlog, alog and dump file information
SWservAt

• Useful ODM Commands
  • odmget – To retrives objects from an Object Class in stanza format
  • odmdelete – To delete objects what meet a specifig criteria.
  • If no criteria specified, all objects are deleted
  • odmadd – To add a new object to an object class
  • odmchange – To change all objects with in an Object Class that meet a
  • specifig criteria
  • odmshow – To display object class definition
  • odmcreate – To create Object Class for application that will use ODM DB
  • odmdrop – To remove an Oobject Class

• Some ODM Command examples
  • To list all records with an Object Class CuDv

# odmget CuDv

• To find out an object within CuAt with condition name=sys0 and attibute=maxuproc

# odmget -q "name=sys0 and attribute=maxuproc" CuAt

CuAt:
name = "sys0"
attribute = "maxuproc"
value = "2000"
type = "R"
generic = "DU"
rep = "nr"
nls_index = 20

• To delete the above object

# odmget -q "name=sys0 and attribute=maxuproc" CuAt > file.1
# odmdelete -q "name=sys0 and attribute=maxuproc" -o CuAt

• To add the deleted object again to the above object class

# odmadd file.1 # add the file content to appropriate Object class
