Oracle Installation Guide - Chapter 4

To manually install the Microsoft Loopback adapter in Windows XP, follow these steps: 1. Click Start, and then click Control Panel. 2. If you are in Classic view, click Switch to Category View under Control Panel in the left pane. 3. Double‐click Printers and Other Hardware, and then click Next. 4. Under See Also in the left pane, click Add Hardware, and then click Next. 5. Click Yes, I have already connected the hardware, and then click Next. 6. At the bottom of the list, click Add a new hardware device, and then click Next. 7. Click Install the hardware that I manually select from a list, and then click Next. 8. Click Network adapters, and then click Next. 9. In the Manufacturer box, click Microsoft. 10. In the Network Adapter box, click Microsoft Loopback Adapter, and then click Next. 11. Click Finish. You next need to make sure that the Microsoft Loopback Adapter is properly configured. 1. Right‐click My Network Places on the desktop and select Properties. This displays the Network and Dial‐up Connections control panel. 2. Right‐click the connection that was just created. This is usually "Local Area Connection 2". Select Properties. 3. On the General tab, select Internet Protocol (TCP/IP), and click Properties. 4. In the Properties dialog box, click Use the following IP address and do the following: a) IP Address: Enter a non‐routable IP address for the loopback adapter. Oracle recommends the following non‐routable address: 192.168.x.x (where x is any value between 0 and 255) b) Subnet mask: Enter 255.255.255.0. c) Record the values you entered. d) Leave all other fields empty. e) Click OK. 5. Close the Network Connections window. The Installer Reports it Cannot Find a File If the installer progress through a part of the installation, then reports that it cannot find a file, the most likely cause is that the directory from which you are installing only has the contents from the first download zip file. You may have unzipped the second zip file into another directory. For your Oracle installation to succeed, the contents of the extraction of both zip files must end up in the same directory. Oracle has provided you with two files for a better Page 55 of 76 download experience; nevertheless, the installer expects there to be a single directory structure containing all of the contents from both zip files. Your first option is to unzip each zip file into the same directory. The second option is to unzip each zip file into different directories, but then manually copy the contents of the second directory into the first. The Installer Tells Me the PATH Exceeds the Recommend Length If the prerequisite checks report a warning similar to the following: Environment variable: "PATH" ‐ This test checks whether the length of the environment variable "PATH" does not exceed the recommended length. Expected Value : XXXX Actual Value : YYYY Then Oracle’s attempt to add its installed directory on the path will not succeed, because the value of the PATH variable is already too long. The “Expected Value” in the error message indicates the maximum allowable length, and the “Actual Value” indicates what the length will be when Oracle’s entry is added. Operating systems including Windows have a maximum length for the value of an environment variable. Environment variables are name/value pairs that control important operating system functions. For some versions of Windows, the maximum is 1024 characters. The PATH environment variable tells Windows where to look for executable files. To function properly, Oracle needs to add its directory to this list. If Oracle’s entry into the PATH variable would cause it to exceed the maximum allowable length, Oracle’s entry will be ignored. The resolution to this problem is for you to remove one or more entries from the PATH. However, do not arbitrarily remove characters or directories from this environment variable as this can cause your operating system to malfunction. Rather, you need to view the contents of the variable, determine what can be removed, and carefully remove one or more directories from the list. One common reason for the variable’s value to be too long is that you have uninstalled software from your system, but its entry in the PATH variable was not removed. If this is the case, simply remove the unneeded directory from the PATH. Another common reason is that you have installed many versions of Oracle or SQL Server. In this case, simply uninstall an unneeded version and ensure that its entry has been removed from the PATH. To view and edit environment variables in Windows 7, first click the Windows icon, right click on “Computer”, and then click “Properties”: Page 56 of 76 Next, click on the “Advanced system settings” hyperlink: On the resulting dialog, click on the “Environment Variables…” button: Page 57 of 76 Page 58 of 76 On the Environment Variables dialog, select “Path” under “System variables”, then click the “Edit…” button: You can now edit the value in the resulting dialog. As previously mentioned, do not arbitrarily delete text here. Rather, carefully determine the directory or directories to delete. Notice that the value is a list of directories separated by a semicolon (;). To save your edits, click the OK button on the open dialogs. Page 59 of 76 The Install Window Disappears If the install window disappears after selecting “Desktop Class” early on in the installation, effectively aborting the install process, after clicking during the screen that looks like the screen below: Then you may need to explicitly tell the installer the location of the latest Java installation. The following steps indicate how to do so: 1. Install the latest version of Java. You can find the latest version of Java on the Oracle web site. Select the one appropriate for your operating system. 2. Remember the path of the Java installation during the Java install. For example, Java version 1.7.0_11 would install itself to a path similar to the following: C:\Program Files\Java\jdk1.7.0_11 3. After extracting the Oracle database zip files as described in this guide, open the command prompt by clicking Start‐>All Programs‐>Accessories‐>Command Prompt. Page 60 of 76 4. Change the directory where you extracted the database install. The “cd” command allows you to do this. For example: 5. Verify that you are in the correct folder by running the “dir” command. You will know you are in the correct directory if you see “setup.exe” in the list of files. For example: 6. Start the database installer by typing the following command: setup ‐jreLoc For example, if our path was as described in step #2, we would type: setup –jreLoc “c:\Program Files\java\jdk1.7.0_11” The installer is now running with the correct version of Java, and the installer window should no longer disappear when selecting “Desktop Class” during the install process. Page 61 of 76 Appendix B: Configuring Oracle Startup Options Your computer may become sluggish after installing Oracle. This can be normal when Oracle is running on a machine with limited resources. When Oracle first starts up it loads the database and performs other initialization. If you have adequate memory to support Oracle and the other programs that you are running on your computer the sluggishness will go away when Oracle has finished these startup operations. The sluggishness also goes away when Oracle is stopped. You will need to have the Oracle instance running only a fraction of the time, so you can stop Oracle when you aren’t using it. You can easily start and stop Oracle by starting and stopping the corresponding service. For an instance named SID, this service is called OracleServiceSID. Just right click on the service such as OracleServiceSID in the Services control panel and select Stop or Start. When the service is stopped it also stops the corresponding oracle.exe process, and when the service is started it also starts the process. To get to the Services control panel in Windows, first open the Control Panel. If you are on Windows XP, it's easier if you click the Switch to Classic View look. Then on XP you can launch the services control panel by going to Start then Settings then Control Panel then Administrative Tools then Services. In some cases, you may see a Services control right there in the control panel. If so, click on it and the services will come up. If you don't see Services, then you need to click on the Administrative Tools icon first. Then you will see Services and can click on that. Once the services control opens, you will see a list of services. Highlight the one that says OracleServiceSID, where SID is the name that you gave your Oracle service when you installed Oracle. The service name will be something like “OracleServiceORCL”. Then click Action/Stop. After a while the Oracle service shuts down the Oracle instance. Of course, once you stop it, Oracle is no longer running, so you'll have to repeat these steps and click "start" to start it again. Or, just rebooting your computer should make the service start again. Your computer will boot more slowly when Oracle is running, because the Oracle services are starting at boot time, and starting an Oracle instance can take a while, particularly on a notebook computer. You can configure Oracle so that it doesn’t start up when you boot your machine. Just open up the OracleServiceSID... service, as described above. But, instead of just clicking stop, you need to change the startup mode. Windows services have one of three startup modes ‐‐ automatic, manual, and disabled. By default, the Oracle service is in automatic mode. This means whenever you boot your computer, the service will start up automatically. You need to change it to manual to keep it from starting at boot time. To do so, right click on the OracleServiceSID... service then click the Properties option. From there, you should see the startup mode, and be able to switch it from automatic to manual. Do the same to the Oracle…TNSListener service. Then next time you boot, those services won't start. Of course, if you set these services to manual startup mode, then when you need to use Oracle, you'll need to go into the services again and start them manually. Page 62 of 76 On recent Windows releases you can also reduce the time to boot while leaving Oracle running by hibernating your computer rather than shutting it down and rebooting it. Restarting after hibernation will take a little longer with Oracle running, but not nearly as long as rebooting with Oracle in automatic startup mode. Page 63 of 76
