This section of behavior settings deals with Environment settings. The available settings are:
| Advanced menu- Environment Settings |
Typical Value | Description |
| ALLOW_DEBUG_URL | YES | Allows user to set up debug level of the application server log. Valid values are YES and NO. If turned off, then the user cannot alter the debug level of the log with a URL. The form of the URL is: http://server.extraview_domain.com/evj/ExtraView?DEBUG=6 The default level of debug messages is 6. Valid values are in the range 1 to 12 |
| ATTACHMENT_REPOSITORY_DMAX | 999 | The maximum number of files or directories that will be created under one node of the external directory structure. The default for this value is 999. It is not likely that this value needs to be altered. |
| ATTACHMENT_REPOSITORY_OPT | INTERNAL | This setting controls whether attachments are stored internally within the database, externally on the file system, or in some combination of the two methods. If the value of this setting is INTERNAL, then all attachments are stored internally within the database. If the value of this setting is EXTERNAL, then all the attachments are stored on the external file system. Alternatively, you may provide a comma separated list of file extensions and then all files with these extensions will be stored externally while all other files will be stored in the database. For example, if you set the value of this setting to "avi, png, gif, jpg" then files of these types will be stored externally. This strategy leaves the files stored internally in the database as searchable by keywords, while the image and video files are stored externally. The default for this value is INTERNAL. Also, ensure that the setting ATTACHMENT_REPOSITORY_ROOT is set correctly before storing attachments outside the database. |
| ATTACHMENT_REPOSITORY_ROOT | The name of the directory on the file system where file attachments will be stored. Before any attachments are stored externally, you must also provide a valid setting for the setting ATTACHMENT_REPOSITORY_OPT. You must also ensure that the path is valid from the application server(s) that are running ExtraView, and that you have all the permissions to read and write to the storage. You must also ensure that you set up a separate backup method for this external storage as backing up your database will no longer backup the file attachments. |
|
| BLOCK_ATTACHMENT_EXTENSIONS | If a user uploads an attachment, or a file into a document field or a file into an image field, with an extension that is in this list, the file will not be stored on the server, and the user will receive a message that informs them that they are not allowed to store files of that type. The default is that all files of all types are stored. The list of file extensions is comma delimited | |
| CACHE_ENABLE_FIX_FOR_IE | NO | There is a bug in Microsoft Internet Explorer which prevents documents being uploaded to a server where there is non-secure back-end server instance in a network with secure proxies. To counteract this, set the value of this behavior setting to YES when you have a network configured in this manner. This is highly unusual and most instances should not need to reset the default value of NO for this setting. |
| CSS_HOME | Only used if you want to override the inbuilt CSS stylesheets for the given image set you access, specified in the behavior setting named IMG_HOME. This is normally not used, as ExtraView will look for the CSS stylesheets as a directory named stylesheets/ within the IMG_HOME path and this is the best location for your stylesheets. If you provide a path for this setting, then you must provide three stylesheets in the directory, named small.css, medium.css and large.css | |
| DEFAULT_ATTACHMENT_CHARSET | UTF-8 | The default character encoding for files being uploaded to ExtraView. This value is used to select the initial value presented to the administrator when creating a new user. |
| DEFAULT_LANGUAGE | en | Default language for the installation. This is typically EN for English |
| DEFAULT_REGION | us | Default region for the installation. This is typically US for the United States |
| DEFAULT_VARIANT | Default variant for the installation. This is not typically used | |
| DOMAIN | Cookie domain | |
| ENABLE_AREAS | YES | This setting controls whether the installation works with multiple business areas or a single business area. Values can be YES or NO |
| ENABLE_PROJECTS | YES | This setting controls whether you can use multiple projects within each business area. Valid values are YES and NO. Note than if you use YES, then ENABLE_AREAS must also be set to YES |
| ENABLE_QUICKFIND | NO | This setting controls whether QuickFind text search is used for keyword searches. Valid values are YES and NO. Note that if you use YES the database must have text indexes created to perform the searches. |
| HELP_HOME | The default for this is a null entry, in which case ExtraView points to ../WEB-INF/locales/en_US/help for the default locale. Localized help can be placed underneath other locales/xx_XX directories, in which case ExtraView will find these automatically, assuming the locale has been created. HELP_HOME can also be set to an absolute URL. If the value begins with "http://", "https://" or "file://", then the value is assumed to be a url pointing to a resource below which is a "help" directory for the help files. | |
| HTTP_CHARSET | UTF-8 | The name of the default character set used within the user's browser. It is recommended that this be "UTF-8" |
| LOCALIZE_TITLES | NO | Used to turn off and on the localization buttons within administration. This is used when you are using ExtraView's multiple languages on the user interface. When this option is set to YES, a button with the title of “Localize” will appear beside all metadata titles and values that can be localized into different languages. Valid values are YES and NO |
| LUCENE_INDEX_LOCATION | The name of the directory on the file system where Lucene full text indexes will be stored. Before any indexes are built, you must also enable full text searching by setting ENABLE_QUICKFIND. You must also ensure that the path is valid from the application server(s) that are running ExtraView, and that you have all the permissions to read and write to the storage. You must also ensure that you set up a separate backup method for this external storage as backing up your database will not backup the full text indexes | |
| MAX_LAYOUTS_IN_CACHE | 1000 | This is the maximum number of layouts that will remain cached in memory once they have been built upon their first access. This layout caching improves the performance of ExtraView significantly. If this number is increased, attention should be paid to the amount of free memory available in the application server. If this number is too high compared to the amount of memory available, then the system may run out of memory |
| MESSAGE_WORKER_COUNT | 1 | The behavior setting MESSAGE_WORKER_COUNT controls the number of Message Workers to be allocated for message and title access. This must be set to an integer from 1 to n. Each Message Worker requires a single Connection to be permanently allocated to that Worker. Therefore, setting this value to a high number (near the ConnectionPool's maximum number of connections, for example), will starve other threads of available connections. Normally 1 is the recommended value. The maximum number should be the maximum number of connections defined in your Configuration.properties file |
| MULTI_LOCALE | NO | ExtraView will behave as a single locale system, using the language specified in the behavior setting named DEFAULT_LANGUAGE when this value is NO. When it is set to YES, then the administrator may add additional language locales to the system, and provide localized messages and metadata for each locale |
| REAL_IP_HEADER | The name of a request header to use to retrieve a client's IP address. This is useful if the application server works behind a proxy or load balancer, and the request comes from that IP, and a header was added with the clients original IP address.
If this behavior setting is configured, and the header exists in the request, and it has a reasonable value, then it is used as the IP address. Many proxy servers, load balancers and some application servers do not set the standard HTTP header properly. This setting may be used when your application server works behind a proxy server or load balancer, and users are seeing unexpected session expiries. |
|
| RESPONSE_COMPRESSION_THRESHOLD | 0 | This setting provides optional compression for the responses to Ajax calls from the user's screen. A setting of 0 does not provide any compression. The value is the number of kilobytes of data that are to be sent to the browser within the Ajax response. When the amount of data to be sent is above this threshold, the data will be compressed on the server, and then expanded by the client browser. There is a tradeoff that is highly dependent on the speed of the network between your users and the server. The higher the volume of data to be sent, the longer the transmission time, but the client browser then needs time to decompress the data. If you believe your installation will benefit from this compression, we suggest starting with a value of around 50. If your network is slow, a smaller number may provide better performance. |
| SERVICE_STATISTICS | NO | YES writes additional statistics to the application server log, providing detailed timings of the execution of each service and how much data was generated and sent to the client browser. NO turns this facility off |
| SITE_URL | The full URL of the site, e.g. http://extraview.company_name.com. This setting is optional. If it is not provided, ExtraView assigns two values internally, one to be used from within the company’s network, and one to be used externally.
When the ExtraView application server initializes, the server will look at the value in this behavior setting. If the incoming request to start the server originated from a SSL session, the two values set internally will similar to: Internal URL: http://extraview.company_name.com/evj The values set can be seen in the application server log in the startup section. If the incoming request to start the server originated from a standard HTTP session, the two URL’s will be identical. There are some circumstances where the administrator will need to set a different URL, and this is done by placing the value directly into the SITE_URL value. The most common reason for requiring this is when you see a notification email from ExtraView, where the Edit button is missing and its URL is malformed. The setting is also sensitive to your web server configuration and any redirection provided there. If you have set up redirection in your web server, these URL's may be different. If SSL is being used within your environment and the URL to access ExtraView therefore begins with https://, then the SITE_URL must be set to https://extraview.companyname.com/evj in order for drill downs from email and other remote applications to work correctly. With redirection, it is probable that you may not use a form such as http://extraview.company_name.com/evj/ExtraView to sign on. It is most probable that you will use http://extraview.company_name.com/evj. If you provide an incorrect value for this setting, it is highly likely that users will not be able to sign on to ExtraView. |

| USER_CUSTOM_CLASSNAME | com.extraview. usercustom. CustomCodeBase |
Log timing data for every user custom method call. Valid values are YES and NO |
| USER_CUSTOM_ENABLE_METRICS | NO | Log timing data for every user custom method call. Valid values are YES and NO |
