For installing and using ATG Search, we need to get ATG licenced install files from ATG, which include a set of EXE files a few JAR files which contains the patches and latest updates. When you have all the necessary files you can start the job. The very first thing you need to install is the

1.ATG2007_1.exe
2.ATG-Merchandising2007_1.exe
3.ATGSearch2007_1-Windows.exe

          With these three files the basic installation is over, now a set of patches need to be installed.
ATG2007_1_p1: This is usually supplied as a JAR file.Open th JAR file using winzip or some similar application.You will find a readme file which will tell you perfectly, how to do the installation and uninstallation of the patches. Incase the readme is not there here are the steps:
1. Shut down ATG 2007.1. If SOLID is running, you must also shut down SOLID before installing the patch. You must also shut down any HTTP servers you may have running.
2. Download/copy the    ATG2007_1_p1.jar    file to your patch directory.
3. From the command prompt, unjar the patch archive file using the command: ” jar xvf ATG2007_1_p1.jar “. This command creates a directory named  ATG2007.1_p1  that contains the patch files.
4. Change to the newly created directory. WARNING: Do not modify or delete files in the patch directory(/patch/ATG2007.1_p1) at any time. Modifying or deleting these files will prevent subsequent installation or uninstallation of patch files.
5. Run the install script using the following command:
On Windows: bin\install.bat
On UNIX: bin/install.sh
The script will install and update several files in your ATG 2007.1 installation.

ATG2007_1_p2 : The step involved in installing this patch is same as that of the above.

Now a few search specific hotfixes are there; which are to be installed inside the Search Directory. Make a folder named hotfix inside the Search2007.1 directory. Unjar the jar file named pr147589_tld. There are two hotfixes mainly and steps for installation are explained below.

Hotfix jsp
(1) Backup folder {DYNAMO_HOME}\Search2007.1\SearchAdmin\AdminUI\j2ee-apps\AdminUI.ear\AdminUI.war
(2) Unjar the pr147589_jsp.jar file into the {DYNAMO_HOME}\Search2007.1\SearchAdmin\AdminUI\j2ee-apps\AdminUI.ear\AdminUI.war
directory to extract the modified jsp files.

Hotfix tld
1. Create a hotfix directory and place pr147589_tld.jar into it (e.g., /hotfix/pr147589_tld.jar).
2.Copy {DYNAMO_HOME}\Search2007.1\SearchAdmin\AdminUI\j2ee-apps\AdminUI.ear\AdminUI.war\WEB-INF\lib\searchadminui1_0.jar into the directory created in (1)
3.Unjar the pr147589_tld.jar into the directory created in (1)
4.Run the command: jar umf META-INF/MANIFEST.MF searchadminui1_0.jar atg/searchadmin/adminui/taglib/ui/elwrap/PagingTagWrapper.class atg/searchadmin/adminui/taglib/ui/PagingTag.class META-INF/searchadminui1_0.tld META-INF/searchadminuiEL1_0.tld
5.Copy the updated file searchadminui1_0.jar back to {DYNAMO_HOME}\Search2007.1\SearchAdmin\AdminUI\j2ee-apps\AdminUI.ear\AdminUI.war\WEB-INF\lib
Note: assuming that the AdminUI.war was backed up in (I-1)
