Table 1 lists the valid UPDATE command
keywords and their associated SETOAM keywords. If a SETOAM keyword
is not on the list, it is not modifiable on the F OAM,UPDATE command.
The following is an example of the syntax to update or set the number of recycle tasks that can be run concurrently: F OAM,UPDATE,SETOAM,[ALL],MAXRECYC,max_recyc_tasks
If the execution of this command is successful, the system issues
the following message:
The following example is the syntax to update or set the number of recycle tasks that can be run concurrently for a specific storage group, or to set the number of recycle tasks that can be run concurrently for all storage groups: F OAM,UPDATE,SETOAM,[ALL|group-name],SGMAXREC,sgmax_recyc_tasks
If the execution of this command is successful, the system issues
the following message:
The following example is the syntax to update or set the default percent valid threshold for RECYCLE:
If the execution of this command is successful, the system issues
the following message:
The following example is the syntax to update the L2TAPEUNITNAME
value:
If the execution of this command is successful, the system issues
the following message:
The following example is the syntax to update the L2DATACLASS value:
If the execution of this command is successful, the system issues
the following message:
The following examples show some F OAM,UPDATE,SETOAM commands:
Assuming TAPEESO is a valid tape esoteric name defined to the system, this command sets the TAPEUNITNAME setting for only GROUP22 to the tape esoteric, TAPEESO. TAPEUNITNAME is the MVS unit name that OAM uses to initially allocate a scratch tape when an object is stored to this Object or Object Backup storage group and stored on a tape volume. If tape volumes already belong to the object or object backup storage group, they are used first before allocating a scratch volume. Even though a tape unit name is specified for the group, the ACS routines (for environment ALLOC) can override the TAPEUNITNAME specification by assigning the allocation to a Tape storage group, thereby, steering the allocation into an ATLDS or an MTL.
This command updates all global values and every storage group name in the active SMS configuration to a TAPEPERCENTFULL value of 90 and a TAPEFULLTHRESHOLD value of 100.
This command updates the values for MOUNTWAITTIME, DEMOUNTWAITTIME, and TAPEPERCENTFULL for only the GROUP22 storage group.
This command updates the value for TAPERECYCLEMODE for expired
object tape volumes in all Object and Object Backup storage groups.
The expired tape volumes remain in their current storage group. When
this command executes successfully, OAM issues the following message:
This command updates the value for TAPERECYCLEMODE for expired
object tape volumes in all Object and Object Backup storage groups.
The expired tape volumes are returned to the MVS scratch pool. When
this command executes successfully, OAM issues the following message:
This command updates the value for TAPEDISPATCHERDELAY to 3 seconds for object tape volumes in all Object and Object Backup storage groups.
This instructs OAM to wait 3 seconds before demounting a tape volume
even if other work is available for this drive. When this command
executes successfully, OAM issues the following message:
