Oracle Enterprise Manager provides Text Manager for configuring, maintaining, and administering Oracle Text indexes. With Text Manager you can perform all of the basic configuration and administration tasks for Oracle Text indexes. You can monitor the overall health of Text indexes for a single Oracle database instance or for the Oracle Real Application Clusters environment. Text Manager provides summaries of critical information and enables you to drill down to the level of detail that you want, to resolve issues, and to understand any actions that may need to occur. You access Text Manager by clicking the Schema tab from the database home page in Oracle Enterprise Manager, and then selecting Text Indexes under the Text Manager group. On the Text Indexes page, select an index name and click View to see information and attributes for that index.
The Text Indexes page shows the jobs that are in progress, scheduled within the last seven days, or are experiencing problems. From this page you can go to the Job Scheduler to see a summary of all jobs for this database instance, and to manage selected jobs. The online help in Oracle Enterprise Manager provides details and procedures for using each Text Manager feature.
This section contains the following sections:
You cannot create an Oracle Text index with Text Manager. Use the CREATE INDEX statement to create an Oracle Text index as described in Indexing with Oracle Text under Creating Oracle Text Indexes.
From the main Text Manager page, you can perform the following actions on the selected index from the Actions list:
Synchronize
Optimize
Rebuild
Resume Failed Operation
Show Logs
Show Errors
You can also schedule jobs for the specified index.
To access Text Manager:
When you select a Text index from the Text Indexes page, options become available for that index for you to edit or perform actions. For example, to configure attributes for searching, click Edit for the selected index. From the Edit Text Index page, you can set attributes, including: Wild Card Maximum Term, Fuzzy Score, and Number of Fuzzy Expansions. You can change index and partition names, as well as specify settings for URL_DATASTORE in addition to other options.
You can use the View Text Index page to see general information about a specific index: index type, parallel degree, synchronization mode, wild card limit, fuzzy score, fuzzy numeric result, datastore, and so forth. Information about any partitions on the index is also available.
To view general information for a Text index:
From the Text Indexes page, click the name of the index in the list of Text indexes.
The View Text Index page opens with the General tab selected.
From here you can select actions to perform maintenance tasks.
You use the Text Indexes page in Text Manager to see the list of Text indexes and general health of the Text indexes for the database instance to help you understand any critical actions that may need to be taken in order to make sure that the entire application is performing properly. Information is displayed such as the status of the indexes and jobs submitted by users during the last seven days. Key information about the Text indexes is also displayed in a tabular form.
Use the Text Indexes page to see:
The number of Text indexes that contain invalid partitions, and which are, therefore, invalid. The number of partitions that are invalid, if any, for all Text indexes is also shown.
The number of indexes that are in an in-progress state, and the number of partitions, if any, that are in an in-progress state.
The number of indexes where all partitions are valid and no activity is in progress.
Sum total of the Text indexes found for this database instance.
Additionally, use the Text Indexes page to see the index type for each Text index, the owner, the number of documents that are not synchronized, total number of documents, and percentage of fragmentation.
You select a Text index from the list and then options become available for that index for you to edit or perform actions.
