Class SessionHandle.PROPERTIES

java.lang.Object

com.solacesystems.solclientj.core.handle.SessionHandle.PROPERTIES

Enclosing interface:

SessionHandle

public static final class SessionHandle.PROPERTIES
extends java.lang.Object

Defines the property names used to create a SessionHandle.

Some Session Properties can also be set as environment variables. If a session property can be set as an environment variable, the API will only look for that environment variable if the property is not specified in the session property list passed to ContextHandle.createSessionForHandle(SessionHandle, String[], MessageCallback, SessionEventCallback).

The names of the environment variables are based on the native library property names. The following environment variables are recognized:

• SOLCLIENT_SESSION_PROP_PASSWORD
• SOLCLIENT_SESSION_PROP_HOST
• SOLCLIENT_SESSION_PROP_GD_RECONNECT_FAIL_ACTION - The acceptable strings for this environment variable are also based on the underlying native library:
  1. "SOLCLIENT_SESSION_PROP_GD_RECONNECT_FAIL_ACTION_AUTO_RETRY"
  2. "SOLCLIENT_SESSION_PROP_GD_RECONNECT_FAIL_ACTION_DISCONNECT"

Constant Field Values

HOST

public static final java.lang.String HOST

The IPv4 or IPv6 address or host name to connect to. Multiple entries separated by commas (up to sixteen) are allowed. With multiple entries, each is tried in turn until one succeeds.

Each entry should provide a protocol, host, and port. The SessionHandle.PROPERTIES.HOST property may also include an optional Proxy Server configuration, separated from the message router configuration by a percent (%) sign.

[Protocol:]Host[:Port][%ProxyService] or [Protocol://]Host[:Port][%ProxyService]

Protocol is the protocol used for the transport channel. The valid values are:

tcp - use a TCP channel for communications between the application and its peers. If no protocol is set, tcp is used as a default. tcps - use a SSL channel over TCP for communications between the application and its peers. The encryption with compression is not supported. http - use HTTP channels or a WebSocket channel over TCP for communications between the application and its peers. Web Messaging with compression is not supported. https - use HTTP channels or a WebSocket channel over SSL for communications between the application and its peers. Web Messaging with compression is not supported.

Host is the IPv4 or IPv6 address or host name to connect to for a connection. IPv6 addresses must be enclosed in brackets ([]).

Port is the port to connect to for a connection. A value is only required when using a port other than the automatically assigned default port number. The default port for TCP is 55555 when compression is not in use, or 55003 when compression is in use. The default port for SSL is 55443. The default port for HTTP or WebSocket over TCP is 80. The default port for HTTP or WebSocket over SSL is 443.

The following examples show how to specify transport channel types. Unless it is otherwise specified, the default port 55555 is used.

192.168.160.28 - connect to IP address 192.168.160.28 and the default port 55555 over TCP. [fe80::1] - connect to IPV6 address fe80::1 and the default port 55555 over TCP. tcp:192.168.160.28 - connect to IP address 192.168.160.28 and the default port 55555 over TCP. tcps:192.168.160.28 - connect to IP address 192.168.160.28 and the default port 55443 over SSL over TCP. tcps:[fe80::1] - connect to IPV6 address fe80::1 and the default port 55443 over SSL over TCP. tcp:192.168.160.28:44444 - connect to IP address 192.168.160.28 and port 44444 over TCP. tcp:[fe80::1]:44444 - connect to IPV6 address fe80::1 and port 44444 over TCP. http://192.168.160.28 - connect to IP address 192.168.160.28 and the default port 80 over HTTP or WebSocket over TCP. https://192.168.160.28 - connect to IP address 192.168.160.28 and the default port 443 over HTTP or WebSocket over SSL over TCP.

When Guaranteed messages are being sent, or when flows are being used to receive Guaranteed delivery messages, the API will automatically reconnect to other listed hosts. However, because another host will not know the state of the publisher flow to the original host, the API must reset publisher flow state. Unacknowledged messages are renumbered and resent by the API. If the alternate router is configured as a replication site this may lead to duplicate messages in the system. It is up to the application to resolve this duplication in what ever way is appropriate to the application.

Applications may wish to configure the session so that auto-reconnect only occurs if no guaranteed messages have been published. This is the legacy behavior of the API. If this is desired then set the session property SessionHandle.PROPERTIES.GD_RECONNECT_FAIL_ACTION to the value GdReconnectFailAction.DISCONNECT. This session property can also be set as environment variable which then allows legacy applications to run without modification or recompile.

Configuring a Proxy Server in a HOST entry

It is sometimes necessary to connect to the message router through a proxy server. The API supports configuring connection through a proxy server in any entry in the list of hosts. If proxy server configuration is required, it follows the message-router configuration and is separated by a percent (%) sign. The host entry format is:

[Protocol:]Host[:Port][%ProxyService] or [Protocol://]Host[:Port][%ProxyService]

ProxyService is a description of the non-transparent proxy. If it is necessary to configure the proxy server that is used to connect to the message router, then the proxy server is configured in the ProxyService string. The ProxyService string format is specified as: [ProxyProtocol]://[username:password@]proxyHost[:proxyPort]

ProxyProtocol is the protocol used to communication with the proxy server. The valid values are: socks5 - Connect to the server with the SOCKS Protocol Version 5, RFC 1928 (IETF Standards Track Document) httpc - Connect to the server with the HTTP Connect Protocol, RFC 2817 (IETF Standards Track Document)

If authentication is required for the proxy server, the username and password may be optionally specified before the proxy host.

proxyHost is the IPv4 or IPv6 address or host name of the proxy server.

proxyPort is the port to connect to for a connection. If the port number is not specified, the default for SOCKS5 is port 1080, and the default for Http-Connect is port 3128.

The following examples show how to connect to a message router through a proxy server.

192.168.160.28%socks5://192.168.1.1 - connect to message router at 192.168.160.28 through a SOCKS5 proxy server at 192.168.1.1. 192.168.160.28%httpc://192.168.1.1 - connect to message router at 192.168.160.28 through a HTTP-Connect proxy server at 192.168.1.1. tcps:solace.company.com%socks5://User:PassWord@proxy.company.com:13128 - connect to message router at solace.company.com using SSL over TCP through a SOCKS5 proxy server at proxy.company.com, port 13128. Authenticate with the proxy server using username User and password PassWord. http://192.168.160.27:44444%httpc://proxy.company.com:11080 - connect to the message router at 192.168.160.28, port 44444, using HTTP. Connect through the proxy server at proxy.company.com, port 11080. [fe80::1]\%socks5://[fe80::2] - connect message router at [fe80::1] through a SOCKS5 proxy server at [fe80::2].

Configuring Multiple Hosts for Redundancy and Failover

Some applications might want to have a list of routers available for connection. Typically these routers will be in separate geographic locations and use of a host list allows applications to fail over to the alternate connections if the first router is unavailable. The host list is configured in the Host property of SessionProperties as a comma separated list of hosts. Each host can optionally include a port number as well. For example, if there are two routers at 192.168.160.128 and 192.168.160.129, but the second is using the non-default port 50005 for the message bus, the SessionProperties.Host would be configured as:

SessionProperties.Host = "192.168.160.128,192.168.160.129:50005"

In this case, when session connect is called, the API attempts to connect, first to 192.168.160.128, if that connection fails for any reason it attempts to connect to 192.168.160.129:50005. This process is repeated until all entries in the host list are attempted. After each entry has been attempted, if all fail, the session properties and SessionHandle.PROPERTIES.RETRY_WAIT_MS determine the behavior of the API. If SessionHandle.PROPERTIES.CONNECT_RETRIES is non-zero, solclientj waits for SessionHandle.PROPERTIES.RETRY_WAIT_MS milliseconds then starts connection attempts again from the beginning of the list.

If an established session fails, to any host in the list, when SessionHandle.PROPERTIES.RECONNECT_RETRIES is non-zero, then API automatically attempts to reconnect, starting at the beginning of the list. Note that the session connect timer, SessionHandle.PROPERTIES.CONNECT_TIMEOUT_MS, runs separately for each connection attempt. So an application waiting for a connection established SolEnum.SessionEvent.UP_NOTICE or connection failure SolEnum.SessionEventCode.CONNECT_FAILED_ERROR could have to wait up to ( (number of hosts in the hosts list) times ( SessionHandle.PROPERTIES.CONNECT_TIMEOUT_MS) for the event.

May be set as an environment variable. (see Session Properties)

Default: empty string

Constant Field Values

BUFFER_SIZE

public static final java.lang.String BUFFER_SIZE

The maximum amount of messages to buffer (in bytes) when the TCP session is flow controlled. Controls the buffering of transmit messages. When sending small messages, the session buffer size should be set to multiple times the typical message size to improve performance. Regardless of the buffer size, the API always accepts at least one message to transmit. So even if a single message's size exceeds this value, it is accepted and transmitted, as along as the current buffered data is zero. However, no more messages are accepted until the amount of data buffered is reduced below this value.
Default: 90000

See Also:

Constant Field Values

CONNECT_BLOCKING

public static final java.lang.String CONNECT_BLOCKING

A blocking connect operation suspends until the Session is successfully connected, including restoring all remembered subscriptions if REAPPLY_SUBSCRIPTIONS is enabled. Otherwise session connect returns SolEnum.ReturnCode.IN_PROGRESS.

Default: ENABLE

Possible values in SolEnum.BooleanValue

See Also:

Constant Field Values

SEND_BLOCKING

public static final java.lang.String SEND_BLOCKING

A blocking send operation suspends when the Session is transport flow controlled, otherwise the send operation returns SolEnum.ReturnCode.WOULD_BLOCK. Successful return from a blocking send operation only means the message has been accepted by the transport, it does not guaranteed the message has been processed by the appliance. For the latter you must used Guaranteed Message Delivery mode.

Default: ENABLE

Possible values in SolEnum.BooleanValue

See Also:

Constant Field Values

SUBSCRIBE_BLOCKING

public static final java.lang.String SUBSCRIBE_BLOCKING

A blocking subscribe operation will suspend when the Session is transport flow controlled, otherwise the subscribe operation returns SolEnum.ReturnCode.WOULD_BLOCK. A successful return from a blocking subscribe operation only means the subscription has been accepted by the transport, it does not guarantee the subscription has been processed by the appliance. For the latter you must use a confirmed operation (see SolEnum.SubscribeFlags.WAIT_FOR_CONFIRM)

Default: ENABLE

Possible values in SolEnum.BooleanValue

See Also:

Constant Field Values

BLOCK_WHILE_CONNECTING

public static final java.lang.String BLOCK_WHILE_CONNECTING

Enable this property to block the calling thread on operations such as sending a message, subscribing, or unsubscribing when the Session is being connected or reconnected.

Constant Field Values

SOCKET_SEND_BUF_SIZE

public static final java.lang.String SOCKET_SEND_BUF_SIZE

The value for the socket send buffer size (in bytes). 0 indicates do not set and leave at operating system default. Note that Linux operating system actually allocates twice the size of the buffer requested in the setsockopt(2) call, and so a succeeding getsockopt(2) call will not return the same size of buffer as requested in the setsockopt(2) call. TCP uses the extra space for administrative purposes and internal kernel structures, and the sysctl variables reflect the larger sizes compared to the actual TCP windows.

Default: 90000

Possible values: 0 or any value greater than or equal to 1024.

See Also:

Constant Field Values

Possible values: 1..255, or 0 to disable publishing Guaranteed messages.

See Also:

Constant Field Values

PUB_ACK_TIMER

public static final java.lang.String PUB_ACK_TIMER

The duration of publisher acknowledgement timer (in milliseconds). When a published message is not acknowledged within the time specified for this timer, the API automatically retransmits the message. There is no limit on the number of retransmissions for any message. However, while the API is resending, applications can become flow controlled. The flow control behavior is controlled by SessionHandle.PROPERTIES.SEND_BLOCKING and SessionHandle.PROPERTIES.BLOCKING_WRITE_TIMEOUT_MS. The valid range is 20..60000.

See Also:

Constant Field Values

CLIENT_NAME

public static final java.lang.String CLIENT_NAME

The Session client name that is used during client login to create a unique Session. An empty string causes a unique client name to be generated automatically. If specified, it must be a valid Topic name, and a maximum of 160 bytes in length. The SessionHandle.PROPERTIES.CLIENT_NAME is also used to uniquely identify the sender in a message's senderId field if SessionHandle.PROPERTIES.GENERATE_SENDER_ID is set.

Default: empty string

See Also:

Constant Field Values

SUBSCRIBER_LOCAL_PRIORITY

@Deprecated
public static final java.lang.String SUBSCRIBER_LOCAL_PRIORITY

A value of 0 (the default) means make a single connection attempt (that is, 0 retries). A value of -1 means attempt an infinite number of reconnect retries (that is, the API will only try to connect or reconnect to first host listed.) NOTE: This property works in conjunction with the connect and reconnect retries Session properties; it does not replace them.

Default: 0. Make a single connection attempt (that is, 0 retries)

Constant Field Values

CONNECT_RETRIES

public static final java.lang.String CONNECT_RETRIES

How many times to try to connect to the host appliance (or list of appliances) during connection setup. Zero means no automatic connection retries (that is, try once and give up). -1 means try to connect forever.

When using a host list, each time the API works through the host list without establishing a connection is considered a connect retry. For example, if a SessionHandle.PROPERTIES.CONNECT_RETRIES value of two is used, the API could possibly work through all of the listed hosts without connecting to them three times: one time through for the initial connect attempt, and then two times through for connect retries. Each connect retry begins with the first host listed. After each unsuccessful attempt to connect to a host, the API waits for the amount of time set for SessionHandle.PROPERTIES.RETRY_WAIT_MS before attempting another connection to a host, and the number times to attempt to connect to one host before moving on to the next listed host is determined by the value set for SessionHandle.PROPERTIES.CONNECT_RETRIES_PER_HOST.

Default: 0. Try the host list once then give up.

Constant Field Values

RECONNECT_RETRIES

public static final java.lang.String RECONNECT_RETRIES

How many times to retry to reconnect to the host appliance (or list of appliances) after a connected Session goes down. Zero means no automatic reconnection attempts. -1 means try to reconnect forever.

When using a host list, each time the API works through the host list without establishing a connection is considered a reconnect retry. Each reconnect retry begins with the first host listed.

After each unsuccessful attempt to reconnect to a host, the API waits for the amount of time set for SessionHandle.PROPERTIES.RETRY_WAIT_MS before attempting another connection to a host, and the number times to attempt to connect to one host before moving on to the next listed host is determined by the value set for SessionHandle.PROPERTIES.CONNECT_RETRIES_PER_HOST.

Default: 0

See Also:

Constant Field Values

RETRY_WAIT_MS

public static final java.lang.String RETRY_WAIT_MS

How much time (in ms) to wait between each attempt to connect or reconnect to a host.
