| The server must be up-to-date with all operating system patches. |
| Data files must reside on an EXT3, EXT4, or XFS file
system. |
Set the VM space to unlimited.
- To verify the current value, in the console
type:
ulimit -v
- To set the value to unlimited, in the console
type:
ulimit -v unlimited
|
Set the number of threads (nproc value)
in the following files:
- /etc/security/limits.conf (global config file)
- /etc/security/limits.d
Recommendation:
The minimum value is 8K but any higher value is
acceptable.
- To find out the current nproc value, in the console
type:
ulimit -H -u
- To set the nproc value, for example to 8K,
use:
ulimit -u 8192
|
The limit for the maximum number of file descriptors per
process is variable, but you must set it to a minimum of 20K. The actual number
varies depending on the complexity of the config.xml file,
specifically the DATE
NUM fields within this file. Since there is no way of knowing
the values of these fields at install time, setting the limit to a high number,
such as 80000, can help to eliminate potential problems.
- To find out the current value, in the console type:
ulimit -H -n
- To set the maximum number of file descriptors per process (for example to
80000), type in the console:
ulimit -n 80000
- To increase the number of file descriptors available on the server, add the
following line to
/etc/security/limits.conf:
* hard nofile 80000
