Oracle: literal does not match format string

Which occurs when we define Date type column and passing strings in different form.
I wanted to overcome this issue when develop oracle DB script.
 There are two solutions available.

• Use to_date function

Eg: - to_date(datestring, formatstring)
to_date('2010-01-05 14:05:29','yyyy-mm-dd hh24:mi:ss' )

• Or alter the evironment Date format

Eg:- alter system/session set nls_date_format='yyyy-mm-dd hh24:mi:ss' scope=spfile;
But this is not good option. System level alter affects all other databases and session level alter also user need to do everytime.

So, create an trigger in your DB script. So it will be executed always when you start your database.
eg: create or replace trigger DATE_TRIGGER
    after logon on database
   begin
      execute immediate 'alter session set  nls_date_format=''yyyy-mm-dd hh24:mi:ss''';
   end;

JmDNS binds with 0.0.0.0 Interface

JmDNS is a java implementation to monitor and register the servers available in our LAN via multicast. It is a 'zeroconf' java implementation.
It is easy to use. We can simply add our own service types(need to register with dns-sd.org)and can use those services without any configuration at our network.
When we register the service we create a new jmdns object. It would be bounded with our interface(mostly our IP). Sometimes in windows it binds with 0.0.0.0 interface and DNS server discovers the service but not returns the service info. It states that service not found or service info is null.
We can overcome above issue while iterating all the interfaces available with the host and avoid

• LocalAddress
• MulticastAddress
• LoopbackAddress
  

Finally bind with your valid interface.
