as well. All file-set information cannot exceed the size of the SPI message
buffer that supports communication between TMFCOM and TMFSERVE, which is
28 KB. If this limit is exceeded, TMFCOM displays Error Message 1050.
You can specify a file-set as a file-name pattern. This pattern resembles a file
name but designates a set of entities (that is, a set of disk volumes, subvolumes,
or files) through the use of pattern-matching (wild-card) characters. The wild-card
characters are:
* An asterisk matches zero or more letters, digits, or a combination of these.
? A question mark matches exactly one letter or digit.
The file-name pattern syntax is:
[[$pattern.]pattern.]pattern
In this syntax, pattern consists of one or more characters. Allowable characters
are letters, digits, asterisks (*), and question marks (?). The maximum length of a
pattern is 8 characters, including wild-card characters. Wild-card characters can
appear in any portion of a name, for as many times as there can be characters in
that portion.
Examples:
BLOCKSIZE { 4 | 8 | 12 | 16 | 20 | 24 | 28 | 32 | 36
| 40 | 44 | 48 | 52}
for dumps to tape, sets the tape data block length, when multiplied by 1024 bytes.
It is more efficient to use large data block lengths, but this is limited by the density
in bits per inch (bpi) at which the tape drive writes tapes. The default is 8.
The following are recommended values for BLOCKSIZE:
If you specify a BLOCKSIZE value larger than 28, but the tape drive selected
cannot handle data blocks this long, TMF uses a block size of 28 KB for the dump
and generates a warning message.
* matches all files in the current subvolume
*z* matches all files in the current subvolume that have IDs containing
the letter “z.”
$DISK?? matches all disk volumes at the current node that have seven-
character names starting with “$DISK,” such as $DISK01” and
“$DISK26.”
P*.* matches all disk files on the current volume that are in subvolumes
whose names begin with the letter “P.”
