As an administrator, you might need
to address performance issues that are not related to any of the query
service or Lifecycle
Query Engine node
configurations. In these situations, you can review and update several
advanced properties.
Important: Use caution
when changing any of the advanced properties. It is not common to
change these settings, and changes might adversely affect the system
performance.
Procedure
- On the Lifecycle
Query Engine Administration
page, under Configuration, click Advanced Properties. By default, you only see a few of the properties.

- Connection Timeout: The timeout value in
seconds for the connection between Lifecycle
Query Engine and
the data source. The default is 60.
- Socket Timeout: The timeout value in seconds
between the establishment of a connection between Lifecycle
Query Engine and
the data source, and the receipt of any data from that source. The
default is 60.
- Reload Log Properties: Logging functions
in the log4j.properties file that are used for
debugging. The logging functions are disabled by default. You can
edit this properties file to enable the logging functions and then
reload the file to begin logging.
- To see a more comprehensive list of properties, click Show
Internal. For more information about each property,
see LQE Properties page in the Jazz.net wiki.
Note: You
can undo any changes that you make by clicking Restore
Defaults.
