![]() ![]() For example, if you approximate that the total amount of data to be crawled and indexed is 10GB, then create a tablespace that is at least 10GB for the Ultra Search instance user. As a general guideline, create the tablespace as large as the total amount of data that you want to index.All data that is collected and processed as part of the crawling and indexing process is stored in this user's schema. ![]() The Ultra Search instance user is a database user that you need to explicitly create.Disk space for the Ultra Search instance user's tablespace.As a general guideline, create a TEMPORARY tablespace as large as available depending on the RAM on your host. Disk space for a large TEMPORARY tablespace.For each remote crawler host, the same amount of disk space as needed to install the Ultra Search server component.In addition, you need 15MB of disk space for the Ultra Search middle tier component. For each Web server host, enough space to install the Oracle HTTP server and related products.Approximately 3 GB of disk space for the iAS infrastructure or database and the Ultra Search server component. ![]() However, as a general guideline, the minimal requirements are as follows: Sufficient Disk Spaceīecause customer requirements vary widely, Oracle cannot recommend a specific amount of disk space. Allocate enough memory for the HTTP server as well as the JDK that runs the J2EE engine. Oracle Corporation recommends using the Oracle HTTP server with the Oracle J2EE container. Regardless of your choice, allocate enough memory for the J2EE engine. However, you might want to install and run this component on the same host as the Ultra Search server component. Therefore, it can be installed and run on a separate host from the Ultra Search server component. The Ultra Search administration tool is a J2EE 1.2 standard Web application. Allocate 50MB of memory for the Web crawler alone. The Ultra Search Web crawler runs as a separate Java process on the same host. ![]() Oracle9i Database Performance Tuning Guide and Reference ![]()
