The Workbench Service Account “mciworkb” must be configured with a ulimit for the number of open files set to at least 10240. This setting is normally configured when you install Information Server.
On AIX, check the /etc/security/limits file which should contain the following lines:-
mciworkb:
nofiles = 10240
nofiles_hard = 10240
If the values are not there or set to smaller values, use the following commands:-
chuser "nofiles=10240" mciworkb chuser "nofiles_hard=10240" mciworkb
On other flavours of Linux, check the file /etc/security/limits.conf file which should contain the following lines:-
* soft nofile 10240 * hard nofile 10240
If these values are not there or set to smaller values, edit the limits.conf file.
