Verify the Limit on the Number of Open Files on Data Aggregator

Verify that the user that is installing Data Aggregator has a value of at least 65536 on the number of open files. Set this value permanently.

Follow these steps:

As the root user or a sudo user, log in to the computer where you are going to install Data Aggregator. Open a command prompt and type the following command to change the ulimit for the open files limit to at least 65536:
```
ulimit -n ulimit_number
```
For example:
```
ulimit -n 65536
```
Open the /etc/security/limits.conf file on the computer where you are going to install Data Aggregator and add the following lines:
```
# Added by Data Aggregator
* soft nofile 65536
# Added by Data Aggregator
* hard nofile 65536
```
Note: Restart Data Aggregator for these changes to take effect. If you are upgrading, the upgrade process automatically restarts Data Aggregator.
To verify that the number of open files is set properly on the computer where you are going to install Data Aggregator, type the following command:
```
ulimit -n
```
The command returns the ulimit number that you specified earlier. The limit on the number of open files on Data Aggregator is set.
