Appendix 1: Properties in the server.properties file

This appendix provides a list of properties in the server.properties file which is created in <install_root>\bin when the first time JReport Server is started, and the detailed information about these properties.

Property Name	Default Value (Range)	Description
CLUSTER
cluster.enable	true/false	Specifies whether or not to activate the cluster feature on the server. This property is available only when the license key you use for your JReport Server is cluster enabled, and the default value of the property varies as follows: If there already exists the server.properties file in `<install_root>\bin` but without the cluster.enable property, after you use the cluster enabled key to launch your JReport Server, the property will be added in server.properties and its default value is true. If there is no server.properties file in `<install_root>\bin`, after you use the cluster enabled key to launch your JReport Server, the default value for cluster.enable is false. When the cluster feature is activated on a clustered server, the server will call the remote methods to accomplish tasks, however by using RMI, the server's performance and reliability will be affected. Therefore, when you want a clustered server to work individually (not in a cluster environment), you can turn off the cluster feature on it by setting this property to false.
cluster.member.id	-	Specifies the member ID for the clustered server. Each clustered server should have an unique member ID. The value of this property should be an integer no less than 1.
cluster.name	jreport-cluster	Specifies the name of the cluster. When the property cluster.enabled is set to true, you must specify a unique cluster name for the servers that will join the cluster to build the cluster.
ENGINE
engine.default_encoding	-	In JReport Engine, this property is used by parameters and export formats (HTML, PDF, RTF, XLS, and e-mail). The property value is used to encode the displaying value of parameters and report data when exporting to these formats.
engine.priority	2 (0 ~ 4)	Specifies the CPU utilization priority for the engine. The performance of JReport Server is influenced by the usage of the CPU that the JReport engine can occupy. A larger share of CPU usage will speed up performance. To tune JReport Server to the best performance, you can modify this option to enable the engine to share a larger part of CPU usage when it is running.
engine.single_thread	true	Specifies that there should be only one thread when the engine is running.
engine.sort.buffer_size	-1	Specifies the buffer size (MB) used in the RAM for each report when sorting on page reports in Page Report Studio. The minimal size required by JReport is 4 MB. The default value -1 means that the buffer size is controlled by the system automatically.
FTPS
ftps.keymanager.algorithm	-	Specifies FTPS key manager algorithm.
ftps.keystore.file	-	Specifies FTPS key store file.
ftps.keystore.password	-	Specifies FTPS key store password.

ftps.truststore.type	-	Specifies FTPS trust store type.
HTTPSERVER
httpserver.admin.port	8889 (1 ~ 65535)	A port used to configure and administer the server remotely. This port is where the servlet for remote administration (jet.server.servlets.RcServlet) listens.
httpserver.backlog	50	The maximum number of Client sockets that can be queued when waiting to be accepted by the JReport Server socket.
httpserver.dashboard.port	8887	Specifies the port for accessing JDashboard page.
httpserver.host.all	true	Specifies whether JReport Server listens on all network addresses. For Linux environment, even if httpserver.host.all=true, at most one IP address can be retrieved because of JDK's own reason. In order to listen on more than one IP address on Linux, you need set httpserver.host.all=false, and then set the desired IP addresses separated by a blank as the value of httpserver.host.name, for example: `httpserver.host.all=false httpserver.host.name=IP1 IP2 IP3`
httpserver.host.name	*	If httpserver.host.all=false, use this property to specify IP addresses that JReport Server listens on. By default this property does not appear in the server.properties file and you need add it manually if you want to use it.
httpserver.max.connections	1000 (1 ~ 2147483647)	The maximum number of connections that a standalone server can accept. New requests sent to a standalone server will be refused when the amount of connections that the server is processing exceeds this number.
httpserver.max.handlers	50 (1 ~ 2147483647)	The maximum number of user handlers that JReport Server can hold. JReport Server can respond to requests from the client-side simultaneously. The number of the executed requests is in inverse proportion to the speed of the response. The more requests that are executed, the slower the speed. To improve the running speed, you can set the maximum number of user handlers to a comparatively small number.
httpserver.name	JREntServer/1.1	Specifies the HTTP Server name.
httpserver.port	8888 (1 ~ 65535)	Specifies the TCP port on which JReport Server listens when the server is started. This port can be an integer between 1 and 65535. However, numbers less than 1024 are usually reserved by system, so numbers larger than 1024 are recommended.

performance.commit.thread	false	Specifies to commit every change in the Version list, Schedule list or Completed list. More Info
performance.compressio	false	Specifies whether or not to compress the temporary data generated during runtime before it is swapped to disk. By compressing the swap files, the I/O efforts in certain circumstance may be considerably reduced so that the overall performance will be improved. Note: Compressing swap files will increase CPU usage because it uses a compression algorithm to shrink data.

By default it is 86400 seconds (24 hours). 300 is the minimum number. If time is out, all the files in the temp folder will be deleted except the files which are being used. The clock count returns to 0 and it counts periodically.
resource.root	%ReportHome%\jreports	Specifies the report root directories of the report resources. You should better set a different root directory for the report resources on each clustered server. This property is created in the server.properties file only when the server is started in a JReport cluster environment.
resource.share.hist.dir	%ReportHome%\history	Specifies the history directories of the report resources on the clustered servers. You should better set a different history folder to store the parameter information and versioning result files on each clustered server. This property is created in the server.properties file only when the server is started in a JReport cluster environment.
resource.share.properties.dir	%ReportHome%\properties	Specifies the properties directories of the report resources on the clustered servers. This is a property which redirects the <install_root>\properties folder in a JReport Server Cluster environment. Each clustered server should use this property to redirect the properties folder to its own location. This property is created in the server.properties file only when the server is started in a JReport cluster environment.
resource.share.realm.dir	%ReportHome%\realm	Specifies the realm directories of the report resources on the clustered servers. Each clustered server should use an individual realm folder to store its security information, such as ACLs, groups, realms, and users. Realms and users are organized into a folder tree structure. This property is created in the server.properties file only when the server is started in a JReport cluster environment.
resource.share.temp.dir	%ReportHome%\temp	Specifies the temporary directories of the report resources on the clustered servers. Each clustered server should use an individual temp folder to store its temporary files generated during its working process, such as the result files generated when you run a report. All the files in the temp folder will be deleted when JReport Server restarts. This property is created in the server.properties file only when the server is started in a JReport cluster environment.
resource.undefine.free	true	Specifies that any resource nodes not bound with an ACL are accessible. By default this property does not appear in the server.properties file and you need add it manually if you want to use it.

Set the value to zero if you do not want to limit the record count. In JReport cluster environment this property will be saved in the server's system database and is not created in the server.properties file.
server.completed.write_in_queue	false	Before a scheduled task finishes, it will write a record into the completed task table. If there are a number of scheduled tasks running concurrently, it is possible that many tasks try to write records into the completed task table at the same time. It will become a bottleneck because the operation is synchronized, and it may block new tasks. To avoid this case, set server.completed.write_in_queue=true, all operations of writing into the completed task table will be performed in a separate thread one by one, and the scheduled tasks need not wait for the operation results to return. By default this property does not appear in the server.properties file and you need add it manually if you want to use it.
server.connection.keepalive	true	Specifies to keep the connection alive after it has connected to JReport Server. Setting this property to false will disconnect the connection once it has received the response. That is, Internet Explorer will not hold the connection open.

The minimum value is 4 MB and can be increased up to 80% of the total Java maximum heap size (for example, -Xmx value in JRServer.bat). All cached report data being used to run reports will share the same memory space. For more about cached report data, see Managing cached report data. In JReport cluster environment this property will be saved in the server's system database and is not created in the server.properties file.
server.cube.maxmemory	0.0	Specifies the allowed maximum memory size in megabytes for all in-memory cubes. The total allocated memory for each cube cannot exceed this value. It does not take into consideration the actual memory used by the in-memory or if some of the cubes are swapped to disk. This value should not be larger than 80% of your Java Heap size. The value must be provided before the admin schedules a cube task for the first time. It can also be specified by the option Maximum Cube Memory Allowed in the Cube Configuration dialog.

server.enable.cachedreportbursting	true	Specifies the mode when scheduling a report with cached report bursting to publish it to the HTML and Page Report Result formats: true - The scheduled result includes full data. Then when end users view the result, they will be displayed the data they are privileged to see according to the cached report bursting setting in the report. false - The scheduled result only contains the data that the user who did the scheduling is allowed to see. For details, see Scheduling to HTML/Page Report Result.
server.enableDynamicResource	false	Specifies whether to enable getting server resources from their real paths. However, when installing JReport Server, if you choose Custom Installation for Standalone Server and with the Enable Resources from Real Paths option checked, the default value of this property will be true.
server.enableMultipleLogin	true	Specifies that multiple sessions created by one user, can exist simultaneously. If the value is true, a user can log onto JReport Server repeatedly without having to terminate any of his/her former sessions until the number of sessions reaches the number permitted by the license. If the value is false, only the newly created session is active, and all the other former sessions created by the same user will be terminated by JReport Server automatically.
server.font.path	<install_root>\font	Specifies a font location for server resources. By default this property does not appear in the server.properties file and you need add it manually if you want to use it.
server.get_remote_host	false	Specifies that JReport Server will automatically record and transmit the IP address of a client who has delivered a request to the engine.
server.http.output_encoding	-	Specifies the encoding of JReport internal servlets. By default, jrservlet uses the JVM's encoding.
server.http.param_values.delimiter	semicolon (;)+	Specifies a delimiter to separate values when a parameter of a report contains multiple values. Valid delimiters include blank space ( ), comma (,), semicolon (;), quotes ("), colon (:), and braces ({}). By default, this property does not appear in the server.properties file. To use a delimiter that is different from the default, add this property to the server.properties file, and then set a value to it.
server.http.secure_cookie	false	Specifies whether or not to set the "Secure" attribute to cookies. Generally only when using a secure protocol, such as HTTPS and SSL, can the browser send back the cookies with the "Secure" flag to the server. For non-secure protocols like HTTP, the secure cookies cannot be sent back. This prevents secure cookies from being observed by unauthorized parties. Therefore, when you are using a secure protocol, you can set this property to true; however if you are using a protocol like HTTP, you may need to keep this property false.
server.invalidate_httpsession_when_logout	true	Specifies whether to invalidate the session when the user logs out.

server.profiling.enable	false	Specifies whether to enable the profiling system. If the profiling system is enabled, JReport Server will collect and store report running information to the profiling database. You can then view profiling report from JReport Server Monitor.
server.realm.active	defaultRealm	Specifies the realm that takes effect when the server starts up. The specified realm should exist, otherwise the server will use an existing realm as active realm. The server will then record a warning message in the log file, and set the selected active realm by this property in the server.properties file. In JReport cluster environment this property will be saved in the server's system database and is not created in the server.properties file.
server.resource.cleanup_user_folder	true	Specifies whether to remove a user's My Reports node (/USERFOLDERPATH/UserID) from the server resource tree when the user is deleted from the security system.
server.resource.enable_linked_catalog	false	When the property is set to true, you can pre-define a linked catalog in the server level for the My Components, Public Components, My Reports and Public Reports folders to inherit. If the property is set to false as default, the My Components, Public Components, My Reports and Public Reports folders cannot inherit linked catalog.
server.restore.task	false	Specifies to re-run all interrupted tasks upon restarting the server, in the event of the server crashing.
server.rmi.auth_file	-	This property enables the server.properties file to locate the rmi.auth file by specifying a path of it, for example, `C:\JReport\Server\bin\rmi.auth`. By default, this property does not appear in the server.properties file.

You can see the message "RMI Report Server started." in the command window when you start up JReport Server.
server.rmiserver.enable	false	Specifies whether to enable the remote method invocation server.
server.rmiserver.fixed_port	0	Specifies a port for exporting server remote objects. If the value is 0, an anonymous port will be used. When JReport Server resides behind a firewall, the only way to pass through the firewall in order to obtain the remote objects from the client side is to use an open port while the remote method invocation server is enabled. This property allows you to specify a fixed port that you can open in the firewall setting.
server.rolebased.authorization	false	Specifies whether to activate the role based security in replace of the default applied security of setting permissions for users, groups and roles. In the role based security, permissions are defined on roles only, and users and groups are mapped to roles.
server.security	true	Specifies whether to enable security checking on remote requests. When it is set to false, responses will be made without any security checking.

performance.cachecat and performance.cacherpt

The process for viewing reports is a combination of both loading reports from disk and generating report files. It is obvious that skipping either one of these two steps will shorten the elapsed time. JReport Server enables you to cache reports and catalogs in memory, so that you do not have to load them from disk, thereby improving performance.

performance.commit.thread and performance.commit.interval

When the value of the performance.commit.thread property is false, JReport Server will commit every change in the Version list, Schedule list and Completed list immediately. For example, upon deleting a scheduled task in the Schedule list, JReport Server will commit the action and refresh the Schedule list. If this value is set to True, JReport Server will only commit changes in the Version list, Schedule list or Completed list in the specified interval. By doing this, you can avoid frequently overwriting any related files in JReport Server, thereby improving performance.

The performance.commit.interval property takes effect only when the performance.commit.thread property is set to True.

performance.max.reports

This property allows you to customize the maximum number of concurrent reports, including background run reports and scheduled reports.

It is meaningful to set this property if your license permits a large number of concurrent reports and you want a smaller maximum number of concurrent reports. Typically the JReport license allows an unlimited number of concurrent reports which can cause too many reports to complete for system resources at the same time.

The valid value range is between 0 and the maximum number of concurrent reports permitted by the license. Setting the property to a suitable value in accordance with your computer's usage will lead to marked improvement in performance. For example, if you have an unlimited license and you don't use queue control, the running speed may be comparatively slow. To achieve better performance, you can set performance.max.reports = 4, so that only four reports run at the same time, while the other reports wait in the queue until one of the four has finished.

By default the property value is 0, which means that the maximum number of concurrent reports depends on the license you have purchased. For example, if you have a 20-report license, it will be up to 20 reports that can be running concurrently. Additional report requests will be placed into a waiting queue.

performance.html.pipeline

To speed up report delivery, JReport Server delivers a single page of content at a time. The JReport Engine outputs the content of the result in an HTML file to the web browser as soon as a single page has finished processing, while the rest of the report continues to be processed.

Note: Data such as Total Page Number displayed in one page is temporary, and is called dirty data. When data in a chart spans across one page, it is also displayed with dirty data. Dirty data is refreshed when the JReport Engine finishes processing.

performance.rptpoolsize

Each cached report uses some heap memory. If the heap memory is used up, an OutOfMemoryException will be thrown.

Flag -Xms specifies the initial heap size and flag -Xmx specifies the maximum heap size. For example, -Xms256m -Xmx512m means that the initial heap size is 256M and the maximum heap size is 512M.

You can refer to Java Virtual Machine documentation for more information.

server.permission.algorithm

Specifies an algorithm for calculating a role, user or group's permission. Two algorithms are supported:

The permission accumulation algorithm
The permission accumulation algorithm is applied if server.permission.algorithm=0.
In this algorithm, a principal's permission is the sum of permissions assigned by the administrator and those inherited from its permission inherit tree. If the administrator did not set permissions or set no permission for the principal, the principal's permissions will be those inherited from the permission inherit tree.
The user permission replacement algorithm
The user permission replacement algorithm is applied if server.permission.algorithm=1.
In this algorithm, if the administrator didn't set permissions for the principal, the principal's permission will be those inherited from its permission inherit tree. However, if the administrator did set permissions for the principal, the principal's permission will be those set by the administrator.

server.version.max_amount_per_subfolder

Specifies the maximum amount of subfolders in each subfolder in the history folder.

By default, JReport Server creates 100 folders in the history folder (<reporthome>\history), and each of these folders can further contain 3000 subfolders (also set by this property). However, these subfolders cannot hold any further subfolders.

First, JReport Server puts the history information, such as archive versions and parameter files, in folder 1. When the amount of subfolders in folder 1 has reached the maximum subfolder amount, it starts to put files in folder 2. When folder 2 is filled up, folder 3 will be used, then folder 4, folder 5, and so on, until all 100 folders have all been filled up.

When all 100 folders have been filled up with subfolders, JReport Server will create another 100 folders, named 101 to 200, and continue storing the history information in these folders, starting with folder 101. When the second 100 folders are full, another 100 folders will be created, then a fourth 100 folders, a fifth 100 folders, and so on.

server.version.from.temp

Specifies to enable the Publish to Versioning System option when previewing a report.

This property functions the same as the Enable "Publish to Versioning System" for Background Tasks View option in the Configuration > Advanced panel of the JReport Administration page.

If the value is set to true, a link Publish to Versioning System will be added to the upper-left corner of the report preview page (preview a report result using the Run command). Click the link to publish the result to version in the current format.
