Advanced Properties page

This table lists the properties in the Lifecycle Query Engine > Administration > Advanced Properties page along with the corresponding release configuration file properties and their description.
UI property Release configuration file property Definition Default value
Advanced Properties Configuration - HTTP
Connection Timeout (seconds) app.http.connectionTimeout HTTP connection timeout 60
Socket Timeout (seconds) app.http.socketTimeout HTTP socket timeout 300
Advanced Properties Configuration - TRS Processing
Create Index for Full Text Search dataset.provider.useFtsIndexes Clear this checkbox to disable creation of the text indexes. Jazz® Reporting Service (JRS) reports that use LQE as the data source do not use the full-text search (FTS) capability that is provided by the Lucene library. Link Index Provider (LDX) also does not use FTS. After you disable FTS, the Full Text Search tab is not present on the LQE Query page.
Note:
  • If you are using IBM Engineering Insights, then FTS is required for LQE.
  • If you decide to re-enable the text indexes after disabling them, LQE re-creates the text indexes on the next startup. Upon the next startup of LQE, it takes almost the same amount of time to create the text indexes as it takes to run the compaction process. For example, if it takes 6 hours for the compaction process, it might take about 6 hours to re-create the text indexes. During the startup process, when the text indexes are re-created, LQE indexing and query functions remain unavailable until the text indexes creation process is completed.
Enabled
