IBM Platform LSF 9.1.1 Fix 343946 Readme File
Abstract
P101035. Fix to allow lim/res to retry attempts to initialize the socket if the system is too busy to release a port.
Description
Readme documentation for IBM Platform LSF 9.1.1 Fix 343946 including installation-related instructions, prerequisites and co-requisites, and list of fixes.
This fix addresses the following issue:
When the system is too busy to release a port, it will cause the lim/res restart to fail because the socket failed to initialize.
This fix introduces the following parameters in lsf.conf to control the retry behavior:
LSF_LIM_STARTUP_RETRY_TIMES
Syntax
LSF_LIM_STARTUP_RETRY_TIMES=integer
Description
The maximum
number of times for lim to repeat attempts to initialize a socket if the first
attempt failed.
Valid values
0
-INFINIT_INT.
INFINIT_INT
is defined in lsf.h.
Default
2. lim
will re-attempt to initialize a socket up to two additional times if the first attempt failed.
See also
LSF_LIM_STARTUP_RETRY_INTERVAL
LSF_LIM_STARTUP_RETRY_INTERVAL
Syntax
LSF_LIM_STARTUP_RETRY_INTERVAL=seconds
Description
If lim failed to initialize
the socket, this parameter specifies the amount of time before lim tries
again (if LSF_LIM_STARTUP_RETRY_TIMES is specified).
Valid values
0 - INFINIT_INT.
INFINIT_INT is
defined in lsf.h.
Default
5

LSF_LIM_STARTUP_RETRY_TIMES
LSF_RES_STARTUP_RETRY_TIMES
Syntax
LSF_RES_STARTUP_RETRY_TIMES=integer
Description
The maximum
number of times for res to try to initialize a socket when the first
attempt failed.
Valid values
0
-INFINIT_INT.
INFINIT_INT
is defined in lsf.h.
Default
0. res
does not try to initialize a socket if the first attempt failed.

LSF_RES_STARTUP_RETRY_INTERVAL
LSF_RES_STARTUP_RETRY_INTERVAL
Syntax
LSF_RES_STARTUP_RETRY_INTERVAL=seconds
Description
If res failed to initialize socket,
this parameter specifies the amount of time to wait before res tries again
(if LSF_RES_STARTUP_RETRY_TIMES is specified).
Valid values
0 - INFINIT_INT.
INFINIT_INT is
defined in lsf.h.
Default
1
