This section addresses prerequisites and preliminary configuration procedures that must be followed before installing ATG Search.
If you are installing on AIX and must run Search using
sudo, note that for security reasons, AIX removes theLIBPATHenvironment variable when usingsudo. To resolve this potential problem you can either setLIBPATHas root before running Search, or set theLIBPATHin the application server’s startup script.Note that running any ATG application as root is not recommended. If at any time you run Search as root or using sudo, the file permissions in the installation change to root. Therefore, you must either continue running Search as root or using sudo, or reset the file permissions.
For any installation in which you are planning to run Search Administration, before you install ATG Search, install your application server and the ATG platform. If you are only planning to run a standalone Search engine, you do not need the ATG platform or an application server.
You will need a scalable, shared network drive where indexes are initially created and from which they can be retrieved by the Search engines. This directory is called the deployment share. All Search engines and Search Administration instances must have access to this directory. Indexes can take up a great deal of disk space, so be sure the directory selected has sufficient space (at least 100 GB, more if your index is large or you plan to archive old indexes). This directory must be writable. In a production site, this directory should be located on a dedicated, high-performance machine.
Note: The deployment share must be created and configured as a shared folder prior to installing ATG Search.
