LSB_MAILPROG, LSB_MAILSIZE_LIMIT
LSB_MAX_JOB_DISPATCH_PER_SESSION
Syntax
LSB_MAX_JOB_DISPATCH_PER_SESSION=integer
Description
Defines the maximum number of jobs that mbatchd can dispatch during one job scheduling
session.
Both mbatchd and sbatchd must be restarted when you change the value of this parameter.
If set to a value greater than 300, the file descriptor limit is increased on operating systems that
support a file descriptor limit greater than 1024.
Use together with MAX_SBD_CONNS in lsb.params. Set
LSB_MAX_JOB_DISPATCH_PER_SESSION to a value no greater than one-half the value of
MAX_SBD_CONNS. This setting configures mbatchd to dispatch jobs at a high rate while
maintaining the processing speed of other mbatchd tasks.
Examples
LSB_MAX_JOB_DISPATCH_PER_SESSION=300
The file descriptor limit is 1024.
LSB_MAX_JOB_DISPATCH_PER_SESSION=1000
The file descriptor limit is greater than 1024 on operating systems that support a greater limit.
Default
300

LSB_MAX_PROBE_SBD
Syntax
LSB_MAX_PROBE_SBD=integer
Description
Specifies the maximum number of sbatchd instances can be polled by mbatchd in the interval
MBD_SLEEP_TIME/10 (6 seconds by default). Use this parameter in large clusters to reduce
the time it takes for mbatchd to probe all sbatchds.
The value of LSB_MAX_PROBE_SBD cannot be greater than the number of hosts in the
cluster. If it is, mbatchd adjusts the value of LSB_MAX_PROBE_SBD to be same as the number
of hosts.
