How Do I Install Electronic signature in Oracle

If you know how to install Linux in VirtualBox then you can install Oracle Database easily.If you dont know how to install Linux go to below link and follow the tutorial - Deploying a Red Hat Enterprise Linux 7 (RHEL7) on VirtualBoxNow you have Linux, to install Oracle Database download the software and follow tutorial - oracle-baseFor more tasks or recovery scenarios in RMAN, follow my blog I post as soon as I get time.DBA Code

Never tried though. You need to download the Linux version of Oracle 11g and install it. Also Oracle provides installation guide for installation and configuration.

signNow is an Apple & Google loved secure e-signature solution. Pricing merely depends your requirement. Check out the pricing of signNow here.

I think I can help!First of all, Oracle is a company, you can’t install it. (I assume you want to install Oracle Database 12c)Why don’t you use Google? A simple search would return you all the guides.If you are not using Google (for hell knows why) you should at least mention on what OS (and distribution) would you like to install it.I Google’d it for you, you just have to press the link: LMGTFYIf you are so lazy now, you will not get too far…Next time do a quick search before you ask a question. No one likes to waste their time on trivial things which can be searched in literally 1 seconds!

Fairly simple...Windows 7 Configuration StepsMake sure you have at least 3 GB of memory on your Windows PC, or that you can allocate 4 GB of memory to your virtual machine (the latter typically requires 8 GB of real memory to avoid extensive disk caching of memory).Install Oracle’s SJDK and run time for Java 6 or 7 on Windows 7 (I installed Java 7). Although either work with the database, you need the Java 6 SDK 32-bit version (at least SJDK 1.6.0_4) for Oracle SQL Developer. This means you need to download the 32-bit version even when you’re installing the 64-bit Oracle Database 11g version. The SQL Developer fix is found in this blog post.Disable Microsoft’s User Access Controls (UAC). I blogged about a set of Windows 7 gripes, and the second point shows you the screen shots that let you disable UAC on Windows 7.Configure your C:\Windows\System32\drivers\etc\hosts file. Use lines 1 through 3 when you’re using a DHCP IP address, and lines 1 through 4 when you’re using a static IP address. If you want to set a static IP address, check this old post on how to set a static IP address. Please note that the hostname needs to be lowercase.127.0.0.1      localhost ::1            localhost 127.0.0.1      db11172.26.126.131 db11Create a user account name that doesn’t have a white space, like admins in the screen shots, and assign it Administrator privileges.The Oracle Enterprise Manager (OEM) uses port ranges above 5,000, which according to Microsoft requires that you set MaxUserPort key in the Windows Registry. You can find more details at this Microsoft Support page. Personally, I haven’t found this necessary and after adding it to please somebody without setting it everything ran fine in Windows 7.Registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\ParametersValue NameMaxUserPortValue TypeDWORDValue Data65534Value Range5000-65534 (decimal)Value Default0x1388 (5000 decimal)DescriptionThis parameter controls the maximum port number that is used when a program requests any available user port from the system. Typically, ephemeral (short-lived) ports are allocated between the values of 1024 and 5000 inclusive. After the release of security bulletin MS08-037, the behavior of Windows Server 2003 was changed to more closely match that of Windows Server 2008 and Windows Vista. For more information about Microsoft security bulletin MS08-037Oracle 11g Release 2 Installation StepsThe Oracle Database 11g Release 2 files are broken down into two zip files on the Oracle site. That means you need to download both files, and then expand them into an installation directory. I called my installation directoryC:\OracleInstall, but you can call it whatever works for you. Here’s a screen shot of the directory after expanding both compressed files (done with WinZip 15).You should notice that the two expanded compressed files put everything into a database directory (or folder). Within the installation folder (C:\OracleInstall\database), you double click on the oui icon to launch (start) the Oracle Universal Installer. It’ll open a command prompt that may dwell on the screen for a few seconds up to maybe fifteen seconds.It’s a good idea to provide an email address for security updates no matter what. You can uncheck the box if you don’t want updates via Oracle Support Services. Click the Next button to continue.Most developers want to Create and configure a database. If that’s your desire, leave the default radio button checked. Click the Next button to continue.Most developers install their test instance on a desktop or laptop. If that’s your desire, leave the default Desktop Class radio button checked. Click the Next button to continue.These are default settings and generally the easiest to use. I’d suggest you change the Character Set drop down to Unicode. Then, enter a password twice. Oracle requires that you use at least one capital letter and one number in a 6 character or more long password. Click the Next button to continue.The next screen is a progress bar that checks for prerequisites. You shouldn’t have to do anything here because it automatically advances you to the next dialog screen. This generally takes less than a minute to run but can take two or so. If you’re much beyond 3 minutes there may be a resource problem with your Windows PC or virtual machine.This shows you all the selected values for the installation. Unless you want to abort the installation, click the Finishbutton to proceed.This screen is the main progress bar, and you’ll be here somewhere between 5 and 10 minutes. The downside is that there are some dialogs that will popup during this phase and you need to authorize them, so it’s a bad time to take a break.The first popup screen requires you to authorize the Java runtime to call home. You should click the Allow Accessbutton to proceed.When the progress bar starts configuring the instance, failures can occur. The first may occur during the network configuration, which typically happens if you didn’t preconfigure the hosts file. You don’t need to do anything but watch here unless the installer triggers an error.The following progress bar is launched by the Oracle Database Configuration Assistant. It typically runs without a problem. You don’t need to do anything but watch here unless the installer triggers an error. This takes a few minutes, and unfortunately requires you to stick aroung to again authorize Java.The second popup screen requires you to authorize the Java runtime to call home. You should click the Allow Access button to proceed.The third and last popup screen asks you to whether you want to open other scheme. Generally, you should click the OK button to proceed.The next dialog shows you that the network and database instances are configured. It’s also running the OEM (Oracle Enterprise Manager) installation. You can wait here but it won’t be a long wait.This is the last dialog and says you’ve installed Oracle Database 11g Release 2 successfully. You can the click Close button to complete the installation.

I used a bare bones centos vm and followed standard install instructions.It was not very difficult though I do not enjoy working with any local databases on local VM's regardless of OS.

Download the 4.3GB one, you just need that one, if you are going to actually put in a virtual machine, else if its for another machine you’ll need something to boot it from, be it a disc or a USB and make them bootables.
