Hi, folks.
I am trying install Oracle Enetrprice Manager 12c (cloud) and i have faced with issue with limited descriptors in Oracle Enterprise Linux 6.5
http://rghost.ru/58055374.view
Error text:
Checking for required ulimit value...
Description:
This is a prerequisite condition to test whether the minimum required ulimit value is available on the system.
Expected result: 4096
Actual Result: 1024
Check complete. The overall result of this check is: Failed <<<<
Recommendation:
1.Update the /etc/security/limits.conf file with the required values, relogin to the shell and perform the install.
2.Check if the ulimit binary exist in path,else it would return a null value for ulimit
Checking for LD_ASSUME_KERNEL environment variable...
Description:
Check for LD_ASSUME_KERNEL
Expected result: LD_ASSUME_KERNEL environment variable should not be set
Actual Result: Variable Not set
Check complete. The overall result of this check is: Passed
After checking i do not see any value (1024) like in error message:

# /etc/security/limits.conf
#
#Each line describes a limit for a user in the form:
#
#<domain> <type> <item> <value>
#
#Where:
#<domain> can be:
# - an user name
# - a group name, with @group syntax
# - the wildcard *, for default entry
# - the wildcard %, can be also used with %group syntax,
# for maxlogin limit
#
#<type> can have the two values:
# - "soft" for enforcing the soft limits
# - "hard" for enforcing hard limits
#
#<item> can be one of the following:
# - core - limits the core file size (KB)
# - data - max data size (KB)
# - fsize - maximum filesize (KB)
# - memlock - max locked-in-memory address space (KB)
# - nofile - max number of open files
# - rss - max resident set size (KB)
# - stack - max stack size (KB)
# - cpu - max CPU time (MIN)
# - nproc - max number of processes
# - as - address space limit (KB)
# - maxlogins - max number of logins for this user
# - maxsyslogins - max number of logins on the system
# - priority - the priority to run user process with
# - locks - max number of file locks the user can hold
# - sigpending - max number of pending signals
# - msgqueue - max memory used by POSIX message queues (bytes)
# - nice - max nice priority allowed to raise to values: [-20, 19]
# - rtprio - max realtime priority

Any ideas?
