How to change hostname to be send to database

[EmreGuloglu1]

Hi all,

RSA IG&L is installed on a host like 'emre.rsa.com'. Target system only accepts hostname 'emre' for incoming connection and resolves it as 'emre.rsa.com'. Formerly that was working but now IG&L sends full name of machine 'emre.rsa.com' to target system and get rejected. Is there a way to manage hostname to be send? Could upgrade of system to 7.1.1 cause to that issue?

Current version is: 7.1.1.161195

Any help would be appreciated.

Could you clarify more what you mean by sending the hostname to the database?

[EmreGuloglu1]

I mean while a collector is trying to connect a database it has a host name which is emre.rsa.com in that case.

So, database knows a connection is established from emre.rsa.com

The issue is that hostname was just emre before but somehow it became emre.rsa.com.

Got it. I'm not sure how this is picked up, but I have a few ideas.

• If you run the command hostname from an SSH session what do you get?
• If it returns emre.rsa.com. Could you share the contents /etc/HOSTNAME and maybe /etc/resolv.conf

Thanks for quick response Mostafa.

hostname command returns emre.

etc/resolv.conf:

search rsa.com
nameserver 10.211.155.151
#nameserver 10.202.173.255
nameserver 10.258.168.141

etc/hostname

emre.rsa.com

I was hoping the output would be different. What type of database are you connecting to? Which JDBC driver class is it using?

[EmreGuloglu1]

Trying to connect a oracle database and using built-in Oracle driver.

Could upgrade cause change of driver?
