uubatch

NAME

SYNOPSIS

DESCRIPTION

External uubatch program binaries (specificaly uucplock) are assumed be runnable with the same path header uubatch was run with (as parsed from argv[0]). This means that uucplock should usually be in the same directory as uubatch.

The program scans each spool directory for C.<> files, which are taken as the names of jobs to consider for batching (if they meet the batching criteria below). Each queued job will be examined to see if the job should be batched. If a job need not be batched then the program simply skips over it. If the job needs to be batched, and the batching succeeds and the batch is sccessfully uuxe'd, the job's data files are deleted.  

BATCHING CRITERIA

uudebat jobs with Data less than MAX_BYTES and more than min_time_before_batch min. old will be batched.

uucdebat jobs with compressed data less than MAX_CBYTES and more than min_time_before_batch min. old will be batched.

Only jobs created more than min_time_before_batch ago are considered for batching, to avoid possible locking problems.

Batching will ONLY be done if at least one rmail job is encountered in the node's spool directory. This saves on unneeded re-batching of uudebat and uucdebat jobs.  

OPTIONS

-c

compression on (default is off)

-B n

MAX_BYTES = n (default DF_MAX_BYTES)

MAX_BYTES is the maximum size (in bytes) of an rmail message or a uudebat job that may be added to a batch Jobs larger than this parameter are not batched.

-C n

MAX_CBYTES = n (default DF_MAX_CBYTES)

MAX_FILE_CBYTES is the maximum size (in bytes) of a uucdebat job's compressed data file that may be added to a batch. uucdebat jobs with compressed data files larger than this parameter are not rebatched.

-S n

CRITICAL_SIZE = n (default DF_CRITICAL_SIZE)

CRITICAL_BATCH_SIZE is the batch size (in bytes) after which we send the batch off and start a new one. Be aware of the fact that the actual MAXIMUM batch size is actually the greater one of :

CRITICAL_BATCH_SIZE + MAX_BYTES_FOR_BATCH

CRITICAL_BATCH_SIZE + uncompressed(MAX_CBYTES_FOR_BATCH)

-T n

min_time_before_batch = n seconds (defaults to MIN_TIME_BEFORE_BATCH)

This is the age of a job (in seconds) before it may be considered for batching.
