High-Volume Performance Testing in Windows Platforms
Running More Than 24 Virtual Testers on a UNIX Agent
383
Note:
These values are in addition to the requirements of other system processes or
applications. The current system values should not be decreased. For example, if other
system processes require SEMMNI=10, do not decrease the value to 1.
For example, for a Solaris Agent running 2000-4000 virtual testers, set system
environment variables as follows:
set semsys:seminfo_semmap=1024
set semsys:seminfo_semmni=4096
set semsys:seminfo_semmns=4096
set semsys:seminfo_semmnu=4096
set semsys:seminfo_semmsl=4096
set semsys:seminfo_semopm=50
set semsys:seminfo_semume=64
set shmsys:seminfo_shmmni=1024
set shmsys:seminfo_shmmax=100072000
set shmsys:seminfo_shmseg=100
set shmsys:seminfo_shmmin=1
System Environment Variable

Total TestManager processes (NPROC,
MAXUP)
The number of virtual testers on the Agent
+ 5.
Total open files (NFILE, NINODE)
(6 * N) + (open_files * N) + (connections * N)
N is the number of virtual testers on the
Agent.
open_files is the number of files explicitly
opened within test scripts.
connections is the number of connections
open concurrently.
Total system-wide shared memory
(SHMALL/SHMMAX)
724 + 5609N + 16S + 13G + group_names
bytes
N is the number of virtual testers on the
Agent.
S is the number of shared variables in all
the test scripts in the suite.
G is the number of user groups in the suite.
group_names is the length of all user group
names in the suite.
Semaphore set IDs (SEMMNI,
SEMMAP)
1
Total semaphores (SEMMNS)
The number of virtual testers on the Agent.
Semaphores per set (SEMMSL)
The number of virtual testers on the Agent.
