OSSACL Job Option
Guidelines

The OPEN job option is not supported for OSS. This OPEN job option has no
effect if you do not specify an SQL/MX object.

Because all SQL/MX files are audited, you should use TMF online dumps as the
primary method for preserving SQL/MX objects. Using the BACKUP command to
preserve files is not an effective recovery if any files are open during the backup
operation. Even if you use the OPEN option, the image saved during the dump of
the database might not be consistent. For more information, see the SQL/MX
Installation and Management Guide.

Backup and Restore 2 normally tries to open files with protected read access.
Other processes can read the files but cannot write to them. If the OPEN option is
in use and the BACKUP command fails to open a file with protected access,
Backup and Restore 2 then attempts to open the file with shared read access.

Before backing up files with the OPEN option, issue an SCF CONTROL DISK,
REFRESH command to update file labels on disk. You must be certain that the
files being backed up are not modified while the BACKUP operation is running.

The OPEN job option is supported only for SQL/MX objects. If you specify this job
option but do not specify any SQL/MX objects, an error occurs. This option is not
supported for OSS objects.
OSSACL Job Option
This job option specifies whether to back up the access control lists (ACLs) in OSS
files. ON is the default.
ON
backs up access control lists (ACL) in OSS files. If an OSS fileset does not support
ACLs, this option is ignored.
OFF
does not back up ACLs in OSS files.
Caution. If you restore a file that was modified or open for write access while being backed
up, file-system error 59 (file is bad) can occur, and data can be lost. Whenever possible, close
all files before running the BACKUP command. If audited files are backed up in the WRITE
OPEN state, they could be corrupt. Restoring such files and using them in audited mode can
cause TMF to leave the whole volume in an inconsistent state. If audited files are restored,
they should be used in nonaudited mode. Use TMF to dump audited files to tape.
OSSACL { ON | OFF }
Note. The OSSACL job option is supported only on systems running G06.29 or later G-series
RVUs and H06.08 or later H-series RVUs.
