This property specifies the authentication scheme.

Supported by: For basic and client certificate authentication schemes, event brokers running Solace PubSub+ version 6.1 and higher. For a Kerberos authentication scheme, event brokers running Solace PubSub+ version 7.0 and higher. For an OAuth authentication scheme, event brokers running Solace PubSub+ version 9.13.1 and higher.
Type: String
Format must be one of the following:
- SupportedProperty.AUTHENTICATION_SCHEME_BASIC (username/password authentication). This is the default authentication scheme.

Browser Timeout

This property specifies the maximum time in milliseconds for a QueueBrowser Enumeration.hasMoreElements() to wait for a message to arrive in the Browser’s local message buffer before returning. If there is already a message waiting, Enumeration.hasMoreElements() returns immediately.

Supported by: Solace JMS API version 6.2 or higher.
Type: Integer
Format: Any value. Default is -1. A value of 0 means wait forever (Enumeration.hasMoreElements() will return false only on closing the browser). A value < 0 will return immediately.
Default: –1

Compression Level

This property is used to enable and specify the ZLIB compression level.

Supported by: Solace PubSub+ event brokers
Type: Integer
Format: Valid values for the compression level are -1 through 9. -1 means use the JNDI connection’s compression level (refer to Compression Level). 0 means use no compression. 1 through 9 enables data compression (where 1 offers the least amount of compression and fastest data throughput, and 9 offers the most compression and slowest data throughput).
Default: –1

Compression Level Property
Property Source	Example
JNDI Connection Factory	SolAdmin—Set through the Compression Level box in the Transport Properties tab of the New JMS Connection Factory or Edit JMS Connection Factory dialog box. CLI/SEMP—Set through Property List “transport‑properties”, Property “compression‑level”.

Connect Retries

This property specifies the maximum number of times to attempt a data connection if the first connect fails. If this value is -1 or greater than 1, and a host list is used, each connect retry will traverse the host list according to the value set for the Connect Retries property.

Type: Integer
Format: Valid values are -1 through 2147483647. 0 means do not perform any automatic connection retries (that is, try once and give up); –1 means retry forever.
Default: 0

Connect Retries Property
Property Source	Example
JNDI Connection Factory	SolAdmin—Set through the Connection Retries box in the Transport Properties tab of the New JMS Connection Factory or Edit JMS Connection Factory dialog box. CLI/SEMP—Set through Property List “transport‑properties”, Property “connect-retries”.

Generate Sender ID Property
Property Source (in descending priority)	Example
Initial Context	env.put(SupportedProperty.SOLACE_JMS_GENERATE_SENDER_ID, true);
JNDI Properties File	Solace_JMS_GenerateSenderId=true

Guaranteed Delivery Reconnect Fail Action

This property specifies to the action to take after a client that was publishing Guaranteed messages is disconnected. The API can do one of the following:

Clear the publisher state and reconnect the publisher flow. Then republish all unacknowledged messages and raise a SolProducerEvent (note that this may cause duplication).
Do not automatically attempt to reconnect the client.

Supported by: Solace PubSub+ version 7.1.2 and higher.
Format: Valid values are SupportedProperty.GD_RECONNECT_FAIL_ACTION_AUTO_RETRY or SupportedProperty.GD_RECONNECT_FAIL_ACTION_DISCONNECT

Host

This property specifies the IP address and port (optional) of the event broker to connect to.

This property is required if you are programmatically creating Connection Factories or looking up Connection Factories from LDAP JNDI stores. The values provided for the Hostproperty overrides the values implicitly set through the URL property used for the JNDI connection.

A host entry uses the following format:

<URI Scheme>://[username]:[password]@<IP address>[:port]

Where:

URI Scheme is the uniform resource identifier (URI) scheme used for the data connection lookup. The valid values are:

smf—use plain-text over SMF for communications between the application and the event broker. SMF is the default.
smfs—use TLS/ SSL protocols over SMF for secure communications between the application and the event broker
ws: or ws://—Use a WebSockets transport for communication between the application and the event broker.
wss: or wss://—Use a TLS/SSL channel over WebSockets for secure communication between the application and the event broker.

username is the user name that is required to authenticate a client connecting to an event broker. A client username can be used by a single or by multiple JMS clients.

password is the username password for the connection when authentication is required.

IP address is the IP address (or host name) of the event broker acting as the JMS broker. To specify a prioritized list of hosts that a client can attempt to connect to, list each IP address, in order of importance, separated by a comma.

port is the port number to use to establish the connection. A value is only required when the client needs to use a port other than the automatically‑assigned default port number. The default port number for is 55555 when compression is not in use, or 55003 when compression is in use. The default port for TLS/SSL connections (with or without compression) is 55443.

Type: String
Format: smf://username:password@ipaddress:port
Default: None

The provided URL parameters are used for both a JNDI connection and a JMS data connection. This is useful when both the JNDI and JMS data connections are for an event broker that provides JNDI and JMS service. However, when the JNDI store to be used is hosted on an LDAP server, and the event broker is only used for the JMS broker, the specified URL parameters, which are used for the JNDI connection, can be overridden by parameters specified in the Connection Factory when creating a JMS connection.

HostProperty
Property Source (in descending priority)	Example
Initial Context	env.put( InitialContext.PROVIDER_HOST, “smf://user:pwd@192.168.1.1:55555”);

JNDI Properties File	java.naming.provider.url=smf://192.168.1.1,smf://192.168.2.1 Host=smf://192.168.1.1,smf://192.168.2.1 This example shows a prioritized list of event brokers.

JMSMessage ID Mode

This property is used to specify how the API should generate a JMSMessageID. It supports two modes:

SOLACE_JMS_JMS_MESSAGE_ID_MODE_DEFAULT—The default mode for generating JMSMessageIDs.

SOLACE_JMS_JMS_MESSAGE_ID_MODE_ASCII_ENCODED_HASH—A mode for generating fixed length JMSMessageIDs that are 23 characters long.

Supported by: Solace PubSub+ version 7.1.2 and higher
Type: String
Default: SupportedProperty.SOLACE_JMS_JMS_MESSAGE_ID_MODE_DEFAULT

Reconnect Retries

This property specifies the number of times to attempt a reconnect once the data connection to an event broker has been lost.

When a host list of event brokers is provided, and no connection is reestablished to any of the hosts, the API can reattempt connecting to the listed hosts again starting with the first host listed. Each time the API works through the host list without establishing a reconnection is considered an reconnect retry. For example, if a Reconnect Retries value of two is used, the API could possibly work through all of the listed hosts without reconnecting to them three times: one time through for the initial connect attempt, and then two times through for reconnect retries.

After each unsuccessful attempt to reconnect to a host, the API waits for the amount of time set for Reconnect Retry Wait property (refer to Reconnect Retry Wait) before attempting another reconnection to a host. It should be noted that the number times to attempt to reconnect to one host before moving on to the next listed host is determined by the value set for the Connection Retries Per Host property (refer to Connect Retries Per Host).

Reconnect Retry Wait

If a connect or reconnect attempt to a host is not successful, the API waits the amount of time (in milliseconds) set for this property, and then makes another connect or reconnect attempt.

When using a list of hosts for the URL property (refer to URL), the Connect Retries Per Host property (refer to Connect Retries Per Host) sets how many connection or reconnection attempts can be made before moving on to the next host in the list.

Type: Integer
Format: Valid values are 0 through 60,000. 0 means do not wait.
Default: 3000 (that is, three seconds)
