ask question : Set UNIX kernel parameters ?

zhangpiwang

我在安装TeMIP V4.0的时候要设置下列系统参数，怎么设置，是在/etc/sysconfigtab文件么
是要信添加，还是修改原来的entry,请指教！
Table 1-4 Setting the UNIX Kernel Parameters Parameter  Recommendation  Recommended Value for Server Products (FS or AM/FM)  Recommended Value for PM Client  Comments  
per-proc-data-size  Must be set to the value of max-per-proc-data-size  -  -  Default value for max-per-proc-data-size is system dependent and provided by Tru64 UNIX.  
per-proc-stack-size  Must be set to the value of max-per-proc-stack-size  -  -  Default value for max-per-proc-stack-size is system dependent and provided by Tru64 UNIX.  
maxusers  Greater or equal to  512  256  -  
max-proc-per-user  Greater or equal to  256  256  -  
max-threads-per-user  Greater or equal to  4096  2048  -  
vm-vpagemax  Greater or equal to  65536  65536  -  
shm-max  Greater than the size chosen for the TeMIP Event Pool  33554432  33554432  Event Pool size at installation time is 2MB. This value has to be increased in most configurations. Refer to Section 5.8 for further details.  
shm-min  Equal to  1  1  -  
shm-mni  Greater or equal to  128  128  -  
shm-seg  Greater or equal to  64  64  -  
sem-mni  Greater or equal to  256  64  For servers in very large production environments, the proposed value may not be suitable. In such cases, apply the following formula: number of active OC + number of Logs + number required by other applications on the system.  
sem-msl  Greater or equal to  128  32  -  


Further details about Tru64 UNIX kernel parameters can be found in the Compaq Tru64 UNIX System Configuration and Tuning documentation.

另外我安装了系统之后，系统要我提供unix 许可认证书，我现在手里还没有，这个怎么在license server中加入，或使用，做应用必须用这个么？如果暂时不添加，时候影响应用呢？那位赐教，并且要是有的话，能给我一份么，zhangpiwang@163.net
