AMI Configuration Guide
Browse to the 3forge > amione > config directory and create a new, empty local.properties file and place each property to override on its own line in the format property.name=value
Hint: You can copy the default.properties to local.properties to get started with good default values.
You might ask, why doesn't AMI just come with a default local.propertiers? This is so that when you download and update to a new version of AMI this file will not be overwritten, hence maintaining your existing settings.
#My local.properties located under config directory
#Note, lines starting with pounds are comments (except for #INCLUDE)
#Override the http port to standard port
#Override the location of the access.txt file
#Process and include properties from a custom properties file
#Define my own custom value
#Reference my custom value
#Append to an existing variable
Common Properties (Applies to Components: Center, Relay, Web, WebBalancer)
- f1.terminate.file: A small file will be created and monitored by AMI. If an external process moves / copies to a file of the same name, but with a ".kill" suffix the process will exit (this provides any easy way for an external script or job control process to cleanly shutdown AMI).
- f1.threadpool.default.size: The number of threads in the core thread pool (this does not include threads for http servicing or image processing).
- f1.threadpool.aggressive: if true will use an "aggressive" thread pool. This pool will wake up faster, but uses more CPU while idle.
- f1.conf.dir: directory to where the configuration files are located, default is config.
- f1.conf.filename: name of the configuration file loaded at start up, default is root.properties.
- f1.timezone: default time zone. For the web component, this will also apply for users that have not saved personalized default preferences
- f1.locale: default locale.
- f1.logs.dir: the root directory for where log files will be deposited.
- f1.plugins.dir: directory of where plugins will be loaded from.
- f1.resources.dir: directory of where additional resources will be placed.

- ami.amilog.stats.period: How often AMI should log general health statistics such as memory, user load, etc. which can be used for real-time/historical monitoring via the performance dashboard. Default: 15 SECONDS.
Relay Configuration Properties (Applies to Components: Relay)
Note: To run the ami relay, include relay in the list of components found in the the ami.components property, ex: ami.components=relay
Relay General Properties (AMI One, AMI Relay)
- ami.relay.id: Sets the unique name of the relay. This is used to distinguish relays on the front end (when there are multiple relays connected to a single center). Each relay should have a unique id
- ami.port: Sets the port that applications connect to on the Relay's host machine. The default port is 3289. See AMI Realtime API
- ami.port.bindaddr: Optional. Specifies the network interface that the ami.port server port be bound to
- ami.port.whitelist: Provide either a list of permitted hostname patterns or plugin for blocking/granting access based on foreign network address. Syntax is either file:<file_containing_a_hostname_patterns_per_line> or text:<comma_delimited_list_of_hostname_patterns> or plugin:<class_name_implementing_com.f1.ami.amicommon.AmiServerSocketEntitlementsPlugin>
- ami.log.messages: If set to true, all messages sent into and out of ami relay to/from other applications will be logged to a file

- ami.relay.guaranteed.messaging.enabled: If true, the relay will use a store and forward journal to record messages to disk prior to an ACK message being sent to the originating client. The journal can also be used to deliver messages to late-subscribing Ami Centers. Default is false.
- ami.relay.persist.dir: Where to store the recovery journal files, if ami.relay.guaranteed.messaging.enabled is set to true. Default is ./persist
- ami.centers: A comma delimited list of centers' host:port to connect to. You can optionally prefix host:port with an alias in the form alias=host:port, in which case the alias will be used to reference the center within the relay.routes file. If an alias is not provided, then the alias is the host:port. Ex: ami.centers=myprimary=localhost:3270,other=some.host.com:3270
- ami.relay.routes.file: a file containing routing tables used for controlling which real-time streaming messages are sent to which center(s). Default is data/relay.routes See Relay Routes File for details. Note, if a file is not found, a placeholder file with instructions will be created there.
The relay can be connected to any number of centers (see ami.centers property). By default, as messages are sent from an external source into a relay they are forwarded to all centers. By adding rules to the relay.routes file (see ami.relay.routes.file) you can control which centers are receiving messages based on any parameters within a message and/or the structure of the message itself. Each line within the file is an isolated rule.
To support dynamic routing, changes to this file during runtime will take effect immediately
Each line in the relay routes file is an isolated rule, with the following format:
|ROUTE_NAME||Unique name of rule|
|PRIORITY||Higher priority rules execute first. Lower numbers have higher priority, with 0 being the highest priority. Ties are determined using alphabetical route name|
|MESSAGE_TYPES||Comma delimited list of messages types, only O (object), D (delete), C (Command) and S (Status) are supported, * - all types|
|OBJECT_TYPES||Comma delimited list of types to evaluate by this rule. Blank - skip rule, * - all types|
|PARAM_TYPES||Comma delimited list of param types for the rule in the format: Name Type [nonull]|
|EXPRESSION||Expression to evaluate, must return boolean, true return value indicates rule succeeded|
|ROUTE_LIST||Comma delimited list of centers to send message to. Blank - no centers, * - all servers|
|ON_TRUE||Action if Expression returns true: BREAK - stop evaluating rules, blank or CONTINUE - continue evaluating next rule|
|ON_FALSE||Action if Expression returns false or null: BREAK - stop evaluating rules, blank or CONTINUE - Continue evaluating next rule|
Starting at the highest priority rule (lowest number), if the MESSAGE_TYPES and OBJECT_TYPES and PARAM_TYPES match the message, then the fields defined in the PARAM_TYPES are extracted from the message and passed into the EXPRESSION. If the expression returns true then the message is sent to all centers in the ROUTE_LIST. The ON_TRUE, ON_FALSE determine what to do next respective to the outcome.
- Lines starting with a pound (#) are considered comments and skipped
- A particular message will only be sent to a particular center at most once, regardless of how many rules it matches
#For NewOrder and Cancel messages with a symbol, route based on symbol. For all other messages router to all centers
RULE0;0;O,D;NewOrder,Cancel;Symbol String nonull;symbol < "F";Center0;BREAK;
RULE1;1;O,D;NewOrder,Cancel;Symbol String nonull;symbol < "Q";Center1;BREAK;
RULE2;2;O,D;NewOrder,Cancel;Symbol String nonull;true;Center2,Center3;BREAK;
O|T="NewOrder"|Symbol="AAPL" <== will be sent Center0
O|T="NewOrder"|Symbol="IBM" <== will be sent Center1
O|T="NewOrder"|Symbol="ZVZZT" <== will be sent to both Center2,Center3

|ON_FAILURE||If all servers in SERVERS_LIST are down, either CONTINUE trying other rules or BREAK and return error to user. Default is BREAK|
Each new client connection is passed through the webbalancer rules engine to determine which list of webservers are candidates for forwarding starting at the highest priority (first) rule.
If the client's ip address (as seen by the webbalancer) matches the CLIENT_MASK portion then a web server from the SERVERS_LIST option is chosen for forwarding, see selection strategy for details. The selected forwarding is "sticky for all subsequent connections from the same client ip address for the life of the session (see ami.webbalancer.session.timeout.period for determining when a session can expire).
Selection Strategy The servers from the SERVERS_LIST with an UP status (see ami.webbalancer.server.test.url property determining UP/DOWN status of a server) and the least number of active client sessions is chosen. With ties broken via round-robin.
Note: If a client address can not be matched to a rule the user will receive an error message.

WebManager Configuration Properties
- ami.webmanager.port: The server port that the webmanager listens on for connections from ami web servers
- ami.webmanager.port.bindaddr: The server port to bind to
- ami.webmanager.port.whitelist: The whitelist used to control connections accepted on the port
- ami.webmanager.mapping.pwd: The working directory for file requests, default is java's path of working directory, typically under 3forge/amione.
- ami.webmanager.mapping.roots: A key=value comma delimited list of roots that web server file requests are mapped to. The key is a "logical name" and the value is the "actual location". Ex: /public=/opt/files,/=/ takes all file requests under /public and maps them to /opt/files, otherwise all files starting with / are mapped to /
- ami.webmanager.mapping.strict: If true, file requests requesting a parent directory (via ..) will be rejected. Also, requests denoting home directory (~) will be directory. Default is true. IMPORTANT SECURITY NOTE: Setting to false will allow remote access to all host files accesible by user process.
Default Authentication Access File ((Applies to Components: Web)
When an authentication plugin is not supplied a configurable "access" file is referenced by default. This is where usernames, passwords, default layouts, and user parameters are defined. The access configuration files lives in the directory of the Web application and is named data/access.txt by default. Each line should contain a single user entry which is pipe (|) delimited containing the following in order:
Username: the username defined is what a user needs to login as.
Password: this is the only place that passwords can be set for users.
Default Layout: if a user is assigned a default layout, they will automatically be classified as a basic user without administrative or developer rights. When the user logs in, they will automatically see the default layout without the ability to modify it. The layout configuration must be exported from the dashboard view. Copy and paste this into a text file and save the file to the AMI Web directory. Call the layout using the name of this text file. See example below.
User Parameters: parameters can be assigned to a user. These parameters can then be used to modify the user's access to data and inputs.
