Form: System Configuration Details

The following fields are configured on the General Settings tab:

Field	Description
Customer Name	This field cannot be modified. The Customer Name is entered during system installation.
CenterView Instance	Any text entered here appears on the application banner. For example if you have multiple instances of CenterView installed (Live, Test etc.) then you can enter a value in this field so that users can easily see which system they are using. After changing this field you will need to restart the browser to see the new value in the banner.
System Email Address	The email address where system generated mails will be sent from.
Default Export Excel Version	The default version of Excel to be used when exporting data from CenterView to Excel.
Validate attribute exists at runtime	Specifies whether or not CenterView should check that an attribute exists when a model attempts to read the value of an attribute from a stream record or a record supplied by a collector. Previously, if no attribute could be found with the given name a Null value was return. If this flagged is ticked CenterView will now treat this as an error.
Allow access to data by default	Specifies the default data access permission on new streams. Possible values are: "T" - By default, all users will be allowed access to the stream data. "F" - By default, no users will be allowed access to the stream data unless they are a member of a user group which is explicitly added to the stream. Note that this is just a default behaviour as any user with the permission to add user groups to a stream may change the data access rights for a stream.
Allow anonymous export by default	Specifies the default access permission on exporting data from a Datasource. Possible values are: "T" - By default, all users will be allowed access to export functionality. "F" - By default, no users will be allowed access to export functionality unless they are specifically configured against the datasource.
Colour of Windows with Focus	Colour for focused windows in CenterView front end.
Colour of Windows without Focus	Colour for unfocused windows in CenterView front end.
Online Support Url	The Url to open when the user requests online support through Centerview.

The following fields are configured on the System Directories tab:

Field	Description
Import File Location	The default base directory path for files to be imported into Geneva. This field can be left blank. See File Collectors for further details.
Export File Location	The default base directory path for files to be exported into Geneva. This field can be left blank. See File Exporters for further details.
Template Location	The location templates when doing excel downloads.
Archive Directory	The default base directory path for data to be archived. This field can be left blank.
Restore Directory	The default base directory path for data to be restored from. This field can be left blank.
Application Location	The location of the CenterView installation.
Plugin Location	The location of any CenterView plugin applications.
Temporary File Location	The location of any CenterView temporary files that are generated.
Performance File Location	The location of the resultant analysis performance files when the system tuning 'Generate Performance Files' check box has been ticked.
Restricted Directory	The root directory path that all files read using File Collectors must reside under. Note that this value is not editable through the GUI and must be set directly within the database.
File Upload Directory	The root location of all uploaded files and all processed incoming email's. The sub directory structure of the resultant (uploaded files/processed email's) is the following:- Uploaded Files: /FileCollector Name/in/YYYYMMDD/UniqueId/ where YYYYMMDD represents the date the files were uploaded and UniqueId is a 32 character unique identifier. Incoming Email's: /YYYYMMDD/EmailId/ where YYYYMMDD represents the date the email was read and processed by Centerview and EmailId is a 32 character unique email identifier. For Email's each EmailId folder will contain a file called body.txt representing the main body content of the email and also any corresponding email attachments.

The following fields are configured on the System Tuning tab:

Field	Description
Thread Pool Size	The number of threads that can be in the pool at any time. This is an advanced option which should not be updated without advice from the CenterView support team. This is generally a small multiple of the number of CPU cores on your machine.
Write Processes Per Stream Set	This is an advanced tuning feature which enables CenterView to multi-thread the process of writing Stream Data to the database. The value of this parameter is dependent upon machine versus database performance.
Database Flush Size	Defines how frequently objects are written to disc. This is an advanced option which should not be updated without advice from the CenterView support team.
Delete Batch Size	Defines the default number of rows to be deleted from a Stream in a single transaction when Archiving or Rolling back data. This is an advanced option which should not be updated without advice from the CenterView support team.
Default Page Size	Defines the default number of rows to be loaded into to a grid when displayed in CenterView. This is an advanced option which should not be updated without advice from the CenterView support team.
Maximum Page/Chart Size	This value limits the maximum number of records that can be displayed in a data grid or graphical chart. It also defines the largest number of records that can be downloaded from a chart in a single file. Downloads with more than this number of records will be split into multiple files which are zipped together.
Default Buffer Size	When reading in data from a collector, this defines how many rows are held in memory before passing them on for processing. This means that if CenterView is reading in 10,000,000 records, it doesn't have to wait until all have been loaded before it begins to process them, but can begin processing after the first 2000 have been read. This is an advanced option which should not be updated without advice from the CenterView support team.
Enforce Pipe Cache Size	If checked, the Pipe Cache sizes below, and per Pipe, are strictly enforced; a pipe lookup which tries to cache too many records will fail and an error will be reported. If not checked, exceeding the cache size on a pipe will result in a warning message.
Default Pipe Cache Size	This value is used when a pipe's cache size has not been set.
Max Pipe Cache Size	This value is the maximum allowed cache size; pipes with caches greater than this will be failed.
Result Expiry Time (sec)	The length of time the CenterView front end application will wait for a result from an asynchronous query before abandoning it. This is an advanced option which should not be updated without advice from the CenterView support team.
Maximum File Size Attachment (MB)	Outgoing Email's will only attach files (zipped or unzipped) that do not exceed this configuration limit. An extra message will appear in the email's message subject/body indicating to the recipient that a file attachment has been removed due to this size restriction. Centerview will not impose any upper limit to the size of the attached files if this field is left blank, hence in this case the underlying email servers will determine if the message is sent/received correctly or not.
Maximum Exporters Errors	If required, you can set the maximum number of errors found, before exporters will stop attempting to export records. This is useful where you process large number of records and do not want to wait until all records are processed in case of errors occurred. This value can be overridden in Exporters.
Generate Performance Stats	If checked, CenterView will generate performance statistics whilst the analysis engine is running.
Log Statistics to File	If checked, logging is enabled and Processing Statistics are written to file.
Stats File Logging Seconds	A period in seconds controlling how often statistical data is written to file.
Log Statistics to DB	If checked, logging is enabled and Processing Statistics are written to the database. See Processing Statistics for further detail.
Stats DB Logging Seconds	A period in seconds controlling how often statistical data is written to the database.

The following fields are configured on the GUI Tuning tab:

Warning: The following are advanced settings which should not be changed without consulting CenterView Solutions.

Field	Description
Maximum Script Run Time (sec)	This sets the maximum time (in seconds) that background clean-up processes in the client application are allowed to run for before handing control back to the user. Setting this too high may result in "Script running slowly" messages.
Inactivity Time (sec)	This sets the amount of time (in seconds) that must pass after a user operation before the CenterView client application will start any background clean-up processes.
GUI Retry Attempts	This field can be used to instruct CenterView to automatically retry a client (GUI) operation if the client receives a network error. If set to a non-zero value, the client will attempt to resend a request to the server the number of times specified by this field. Each time a request is resent, the GUI will indicate on the status panel the total number of errors received so far and the time of the last error. This setting should only be used if your network is unreliable. By default this field is set to 0.
GUI Retry Interval (ms)	If "GUI Retry Attempts" is set to a non-zero value, this field indicates how long (in milliseconds) the client waits until it attempts to resend a failed request to the server. Typically this is set to 500 milliseconds.

WARNING: You must re-start the CenterView client for changes to take effect.

The following fields are configured on the Advanced tab:

Field	Description
System Language	The system language code specifies which language should be used for login screens and for all non interactive messages.
Default Character Set	The character set CenterView assumes when reading from or writing to any plain text or CSV file. Please note that this must be a character set supported by the Java virtual machine and that multi byte settings such as UTF8 (e.g. for Japanese etc.) are supported.
Line Separator Style	The user can specify a default line separator style that will be used by File Exporters where no particular line separator has been specified. If the user does not specify a default style here then the default will revert to be the default of the operating system on which the CenterView server is running. In addition you can specify the line separator on each file exporter where a particular exporter needs to use a style other than the system default.
Data Storage Group	The Data Storage Group to use when creating tables to store Stream data. This field is interpreted differently depending on the underlying database: On Oracle, a Data Storage Group is equivalent to a Tablespace. On SQL Server, a Data Storage Group is equivalent to a Filegroup. If no Data Storage Group is specified, the database user's default setting will be used.
Default Stream Storage	This specifies the default Storage Type when creating a new Stream. Database: Store the data in a regular table within the CenterView database. This is the most common option Database (Partitioned): Store the data in a partitioned table within the CenterView database. This option provides improved performance for rollback and archiving of very large Streamsets. The option is only available if "partitioning" is available within your database installation. In Memory: Data for the Stream will not be written to the database. This option can be used (for example) when you want to aggregate large amounts of unsorted data which can then be written to a stored Stream.
Effective Date	Effective date to be used when date override is in use.
Schema Version	Read only: the version of the schema currently installed.
Licence Key	This is the Licence Key for your CenterView Installation which is provided by CenterView Customer Support. If CenterView is not configured with a valid key, analysis tasks will not run and an error message will be displayed in the log file. A Licence key can sometimes be associated with an expiry date. If the licence has expired an additional field will show the expiry date. After a licence has expired CenterView will generate warning messages in the analysis logs for 28 days beyond the expiry date. After this time analysis tasks will cease to run.
Delete Log Messages after Days	If this field is set, a System Task, when run, deletes Log Messages and Managed Files for Log Files older than this number of days. See Task Plans for how to set up and run a System Task.
Archive deleted log messages to file	Whether to archive Log Messages to file before deletion. Archived Log Messages are written to archive files in the Archive Directory (see above). There is no option to archive Managed File entries to file before deleting them.
Default Password Policy	The password policy selected by default when creating new users. Password Policies can be edited in the Password Policies List
Allow Reset Configuration	Before performing a 'Reset Configuration' the administrator must tick this checkbox to allow access to reset the configuration. WARNING: Resetting the configuration will delete all configuration data in the CenterView Instance. See Configuration Reset for how to reset the configuration
Delete Stats Records after Days	If this field is set, a System Task, when run, deletes Processing Statistics records from the Database older than this number of days. See Task Plans for how to set up and run a System Task.
Archive deleted Stats Records to file	Archiving is not yet available for Processing Statistics records that have been deleted. Records are currently only deleted after the number of days specified in the System Configuration 'Delete Stats Record after Days' field.

The following fields are configured on the Active Directory tab:

Field	Description
Default Domain	The default Domain which will be initially selected on the login screen.
Active Directory Login Group	Names of Active Directory Groups whose members are allowed to log in into the CenterView. Names can be separated by a semicolon. Use {instance} to include the CenterView instance name.
