KB10542: “Maximum number of open files 256 is low; please increase to 1000 or greater.” warning message appears when starting MicroStrategy Intelligence Server Universal on Solaris.

SYMPTOM:
When starting Strategy Intelligence Server Universal on Solaris, the following warning may appear on the standard output and in the DSSErrors.log:
 
 

mstrexec-iserver: WARNING: maximum number of open files 256 is low; please increase to 1000 or greater.

 
CAUSE:
In Solaris, every process is subjected to a System Kernel Parameter that defines the maximum number of files that it can have open. "rlim_fd_cur" specifies the “soft” limit on file descriptors that a single process can have open. A process might adjust its file descriptor limit to any value up to the “hard” limit defined instead by rlim_fd_max.
 
ACTION:
In order to increase “hard” and “soft” limits on file descriptors it is necessary to directly edit the root /etc/system file by adding the following lines:
 
1.  Set hard limit on file descriptors

1. 
   set rlim_fd_max = 4096

   
   
2. Set soft limit on file descriptors

3. 
   set rlim_fd_cur = 1024
   

   
   

Note: This hard limit can be verified by using the following command:

ulimit -a -H
