Access Controls
D-4 Oracle Secure Backup Installation and Configuration Guide
that emptied state. Because there is only one obacslibd daemon controlling each ACS
tape library , no other tape library operations are permitted until the CAP is cleared.
You can control how long an outstanding request waits for the CAP to be cleared with
the
maxacsejectwaittime
policy.
Oracle Secure Backup does not support the
importvol
command for ACSLS tape
libraries. You can use the ACSLS cmd_proc utility to enter a volume into the tape
library.
Access Controls
ACSLS optionally allows fine-grained access control over the commands that a user
can issue and the volumes that can be accessed. Setting up the ACSLS access controls
is done at the ACSLS console. Oracle Secure Backup does not support setting,
modifying, or displaying the ACSLS access controls.
If ACSLS access control is enabled, then a user must have the correct
acsls_access_
id
to access the ACS device. Oracle Secure Backup maps this
acsls_access_id
,
which is defined on the obtool
mkdev
or
chdev
commands, to the Oracle Secure
Backup device object.
Scratch Pool Management
ACSLS enables you to define one or more scratch pools to which a blank or recycled
volume can be assigned. Subsequent scratch mount requests are then restricted to
volumes in the pool or pools specified with the request. Oracle Secure Backup offers
equivalent functionality with an optional scratch pool ID for
media family objects.
When a volume is pulled from the scratch pool, Oracle Secure Backup automatically
labels the volume with a permanent media family when its volume header is written.
You are not required to label volumes with the
labelvol
command beforehand. This
ensure that separation of tapes within the tape libraries is persistent.
When an
unlabelvol
operation is performed, the tape is put back into the scratch
pool that is defined within the current definition of the media family.
Oracle Secure Backup does not support creating scratch pools, entering cartridges into
a scratch pool, or removing cartridges from a scratch pool. These operations must be
performed at the ACSLS console.
