When you build the PRIMECLUSTER system, the default values for the kernel parameters of the Solaris may be inadequate. The Kernel Parameter Worksheet shows the kernel parameter values used for PRIMECLUSTER.
Set up the kernel parameter as follows according to the type of "Characteristics" included in the table.
Addition
Specify the total of the system default value and the recommended or specified values for each software product.
Maximum value
Specify a maximum for the recommended or specified values for each software product.
You must, however, use the default value if the maximum value is smaller than the system default value.
The kernel parameter values differ depending upon:
CF configuration
RMS configuration
Using GFS
Using GLS
See
For details of the kernel parameters and instructions on changing parameter values, see "Solaris System Administration" in "Solaris X System Administrator Collection Vol. 1."
For information on the default values of the Solaris, see the "Solaris Tunable Parameters Reference Manual."
Note
The values used by products and user applications that operate in the PRIMECLUSTER system must also be included in the kernel parameter values.
To enable values that have been changed, you must restart the system after the installation.
If a kernel parameter value is already maximized, the change will not be added to the system.
If a process is started without process monitoring from a state transition procedure, the hard- and software limits in the file descriptor (fd) for that process will both be "1024", even after changing the kernel parameter values.
If a process started from a state transition procedure requires a file descriptor above "1024", please add a "ulimit" definition at the beginning of processing for the state transition procedure, and specify the maximum value for the file descriptor.
