Table 3–4 (Cont.) Attributes of the engine element
Attribute Valid values Description
Configuring Reports Server
maxIdle number Default: 30
The number of minutes of allowable idle time
before the engine is shut down, provided the
current number of engines is higher than
minEngine.
For example, if minEngine is 0, maxIdle is 30,
and one engine has been running but unused for
30 minutes, that engine will shut down. If, under
the same conditions, minEngine is 1, the active
engine will not shut down, even if it has been idle
for 30 minutes.
callbackTimeOut number Default: 60000
The number of milliseconds of allowable waiting
time between when the server launches an engine
and the engine calls the server back.
If the machine that hosts the server is very fast,
you can reduce this number for faster
performance.
defaultEnvId string Is an optional attribute. It specifies the default
environment with which Reports Server starts an
engine. The attribute takes an id that is associated
with an environment element in the server
configuration file.
If you specify defaultEnvId, Reports Server
starts an engine with the environment variables
specified in the referenced environment element
plus whatever environment variables that
Reports Server is running under.
If you do not specify defaultEnvId, Reports
Server spawns engines with the environment
settings in force at startup time.
For more information refer to Dynamic
Environment Switching.
engineResponseTime
Out
number Default: null (no timeout)
The maximum amount of time (in minutes) for an
engine to update the status of the job while
running a report in your environment. If it takes
longer than this amount of time to update the job
status for some reason (e.g., due to the engine
hanging or a long blocking SQL query), Reports
Server terminates the job.
jvmOptions string The Java Virtual Machine (JVM) options to be
used by Reports Server when it starts an engine
in the JVM. For example, you can use this
attribute to specify the starting heap size and
maximum heap size for the JVM, additional
classpath entries, and so on.
The Reports Engine running in the server
environment ignores the value in the REPORTS_
JVM_OPTIONS environment variable. You need
to add the value of the environment variable to
jvmoptions attribute in order to let the Reports
Engine pick up the JVM options.
