How to find out all installed software in our RedHat Enterprise 5 server?

Question

DBConn dBConn = new DBConn();
PreparedStatement prepareStatement;

Connection con = dBConn.getDBConnectionForPro();
prepareStatement = con.prepareStatement("SELECT * FROM TBL_MASCONFIGTTB WHERE SERVICE_NAME=GUPSHUP AND VALUE=TRUE");

if (prepareStatement.equals("true")) {
    System.out.println(GenerateLinkDaoImpl.sendOTP("90xxxxxxxx", smsBody));
}
else {
    System.out.println(GenerateLinkDaoImpl.SendSms("90xxxxxxxx", smsBody));
}

Solution 1

To get a list of all installed rpms, you can do rpm -qa. To find out which config files have changed, you can again use rpm: rpm -qa | xargs sudo rpm -q --verify --nosize

Anything that was installed without using rpms is a wild guess, but you should get a good idea from looking at /opt, /usr/local and /home

Solution 2

If you install all rpm packages then you can type rpm -qa to give you a list. There are other ways to install software (like tarballs) and those aren't tracked ( by the rpm database or any other method that I'm aware of.).

You can use multi threading to achieve.

What do you mean call multiple URLs ?

Hello and welcome on stack overflow! Your code seems functionnal to me, perhaps you could add some info on the functionality you are trying to implement?

Why do you think prepareStatement.equals("true") would ever evaluate to true? prepareStatement is a PreparedStatement, so it will never be equal to the String "true". What are you trying to do?

Just want to add another way to make a list of installed software: yum list installed
