This subsection describes the estimation of resources used by performance tracer for each OS.
This section describes the estimation of resources used by performance tracer when using Windows.
Calculate the file size (Unit: Bytes) for shared memory used by performance tracer for each PRF daemon. The formula for calculating is as follows:
Formula for calculating disk occupancy of %PRFSPOOL% is as follows:
The above mentioned disk capacity is a rough indicator. As a result, create the %PRFSPOOL% with enough excess space.
You must consider the following values and set up the kernel parameter to use the performance tracer when using AIX. If the settings are not done properly, the processes of performance tracer cannot be invoked or while running the processes they might terminate abnormally due to insufficient resources. For the kernel parameter settings, see the manual of the OS being used.
Calculate the file size for the shared memory (Unit: Bytes) used by performance tracer for each PRF daemon. The formula for calculating is as follows:
Set up the file size for shared memory using the environment variable EXTSHM. Set up in such a way so that shared memory allocated is greater than the value calculated in the formula for calculations.
Set up the number of file descriptors in nofiles of the /etc/security/limits file. Set up the number of file descriptors used when invoking the PRF daemon as 32 and above.
The formula for calculating the disk occupancy of $PRFSPOOL is as follows:
The above mentioned disk capacity is a rough indicator. As a result, create the $PRFSPOOL with enough excess space.
You must consider the following values and set up the kernel parameter to use the performance tracer when using HP-UX. If the settings are not done properly, the processes of performance tracer cannot be invoked or while running the processes they might as well terminate abnormally due to insufficient resources. For the kernel parameter settings, see the manual of the OS being used.
Calculate the file size for shared memory (Unit: Bytes) used by performance tracer for each PRF daemon. The formula for calculating is as follows:
Set up the file size for shared memory by shmmax of Kernel Configuration. Set up in such a way so that shared memory allocated is greater than the value calculated in formula for calculations.
Set up the number of file descriptors by maxfiles of Kernel Configuration. Set up the number of file descriptors used when invoking the PRF daemon as 32 and above.
The formula for calculating the disk occupancy of $PRFSPOOL is same as AIX. Reference the formula for calculations of AIX.
You must consider the following values and set up the kernel parameter to use the performance tracer when using Linux. If the settings are not done properly, the processes of performance tracer cannot be invoked or while running the processes they might as well terminate abnormally due to insufficient resources. For the kernel parameter settings, see the manual of the OS being used.
Calculate the file size for shared memory (Unit: Bytes) used by performance tracer for each PRF daemon. The formula for calculating is as follows:
Set up the file size for shared memory in kernel.shmmax of /etc/sysctl.conf file. Set up in such a way so that shared memory allocated is greater than the value calculated in formula for calculations.
Set up the number of file descriptors in nofiles of /etc/security/limits.conf file. Set up the number of file descriptors used when invoking the PRF daemon as 32 and above.
The formula for calculating the disk occupancy of $PRFSPOOL is same as AIX. Reference the formula for calculations of AIX.
You must consider the following values and set up the kernel parameter to use the performance tracer when using Solaris. If the settings are not done properly, the processes of performance tracer cannot be invoked or while running the processes they might as well terminate abnormally due to insufficient resources. For the kernel parameter settings, see the manual of the OS being used.
Calculate the file size for shared memory (Unit: Bytes) used by performance tracer for each PRF daemon. The formula for calculating is as follows:
Set up the file size for shared memory in shmsys:shminfo_shmmax of /etc/system file. Set up in such a way so that shared memory allocated is greater than the value calculated in formula for calculations.
Set up the number of file descriptors in rlim_fd_max of /etc/system file. Set up the number of file descriptors used when invoking the PRF daemon as 32 and above.
The formula for calculating the disk occupancy of $PRFSPOOL is same as AIX. Reference the formula for calculations of AIX.
