CREATE CONTAINER
(The other files in this directory are owned by the OpenVMS users whose proxy
database entries correspond to the UNIX owner UIDs of the individual files.)
/ROOT_MODE=n
Optional. Default: 755 (provides the following protection for owner, group, and
world rwx-rx-rx).
UNIX protection of the default container files: root directory, bit map, and
superblock.
Specify octal values in the following order: for user, for group, for others. The
values are:
• 0 — No access
• 1 — Execute access
• 2 — Write access
• 3 — Write and execute access
• 4 — Read access
• 5 — Read and execute access
• 6 — Read and write access
• 7 — Read, write, and execute access
For example, /ROOT_MODE=751 provides:
User Read, write, and execute access 7 rwx
Group Read and execute access 5 rx
Other Execute access 1 x
/SIZE=option=value
Optional. Default: /SIZE=(INITIAL=8917,EXTEND=160,MAXIMUM=0).
Specifies the following file size attributes:
• INITIAL
Specifies the initial size, in OpenVMS blocks, of the container. Maximum
value: 8917.
• EXTEND
When an extension is necessary, specifies the number of blocks by which the
container is extended. Maximum value: 8192.
Note
Using large values might impact system performance and disk usage. In
most cases, the default is sufficient.
• MAXIMUM
Specifies the maximum size of the container.
If the value is zero, the size of the container file can increase without limits.
/UID=n
Optional. Default: UID in the selected proxy record.
