This appendix describes updating the configuration file(s) changes the Oracle DataLens Server configuration and requires a server restart before the change will take effect.
Stop and re-start the server using the platform specific commands. During the Oracle DataLens Server downtime, active clients may fail to complete the current request.
Oracle recommends that you use the default properties in this file. Configuration files residing within the Oracle DataLens Server installation define the Oracle DataLens Server configuration. The Java Property file and XML document configuration file formats are used.
This file is a Java property file. Unlike typical Java properties files, where properties are identified by a simple "key", data lens configuration files utilize a "path" based property specification. The path is a dot-separated list of names identifying the object. Lower case names in the path correspond to the application logical object structure, and the leaf element (starting with a capital letter) specifies the property name. The property value is separated from the property identifier by an equal sign.
For example, the following property file fragment may be used to configure the Administration web pages Statistics display:
# Any Production or Administration Server can send statistics if this flag is # turned on. The Transform server will not send statistics. Server.send.statistics=true
Some useful options for the server.cfg
file are displayed in the following table.
Server.send.statistics=true |
Any Oracle DataLens Server will send statistics if this flag is turned on. |
Server.qi.failure.count=100 |
Shows the number of failures that will be accumulated by project. 0 or no entry means do not accumulate at all. |
Server.cookie.life.minutes=60 |
Lifetime of login information stored in local cookies (default is 1 hour). |
statistics.chart.bgcolor=#FFFFCC |
Background color to use for the charts and chart keys. |
server.nle.instances=3 |
Set the number of parameterized domain instances that will be loaded into memory. A single domain with two instances might want to set instances to 3. 1 for the first parameterized domain, another for the second, and a third for both in memory. |
wfg.maxmemorylines=15000 |
Set the number of lines of data to keep in memory between the steps of a DSA. If the number of lines of data is greater than this parameter, then the data is written to disk between each step of the DSA, which hinders performance. This is the Processing Chunk Size value, see "Configuring Server Constants". |
