Connection Parameter Reference

PGDBNAME

Specifies the database name. You do not need to set this parameter in the URL because it is automatically parsed from the .properties file.

Property type: string

PGHOST

Specifies the IP address of the host. You do not need to set this parameter in the URL because it is automatically parsed from the .properties file. Both IPv4 and IPv6 addresses are supported. If multiple CNs are configured, use colons (:) to separate their IP addresses and port numbers, and use commas (,) to separate CNs.

Property type: string

PGPORT

Specifies the port number of the host. You do not need to set this parameter in the URL because it is automatically parsed from the .properties file.

Property type: integer

user

Specifies the database user who creates the connection.

Property type: string

password

Specifies the password of the database user.

Property type: string

driverInfoMode

Controls the output mode of the driver description information.

Property type: string

Value range: OFF, INFO, DEBUG, and TRACE (case-insensitive).

• OFF: The logging function is disabled.
• INFO, DEBUG, and TRACE logs record information of different levels.

Default value: No default value is provided. If this property is not set, the value INFO is used.

loggerFile

Specifies the log output path (directory and file name). Generally, the log directory and file name must be specified.

If only the file name is specified and the directory is not specified, logs are generated in the client running program directory. If no path is configured or the configured path does not exist, log streams are output by default. This parameter has been deprecated and does not take effect. To use this parameter, you can configure it in the java.util.logging .properties file or system properties.

Property type: string

logger

Specifies the log output framework used by the JDBC driver. The JDBC driver supports the log output framework used for interconnecting with user applications. Currently, only the Slf4j-API-based third-party log output framework is supported. For details, see Log Management.

Property type: string

Value range: Slf4JLogger and JdkLogger

• If it is left empty, the JDBC driver uses JdkLogger.
• The third-party log framework based on Slf4j-API is used.

allowEncodingChanges

If this parameter is set to true, the character set type can be changed. This parameter is used together with characterEncoding to set the character set. The two parameters are separated by ampersands (&). Example: allowEncodingChanges=true&characterEncoding=UTF8.

Property type: Boolean

Value range:

• true: The character set type can be changed.
• false: The character set type cannot be changed.

Default value: false

characterEncoding

It must be used together with allowEncodingChanges. When allowEncodingChanges is set to false, characterEncoding can be set only to UTF8. When allowEncodingChanges is set to true, set characterEncoding as permitted.

Property type: string

Value range: UTF8, GBK, Latin1, and GB18030.

Default value: UTF8

currentSchema

Specifies the schema of the current connection. You need to specify a schema in search-path. If the schema name contains special characters except letters, digits, and underscores (_), you need to enclose the schema name in quotation marks. Note that the schema name is case-sensitive after quotation marks are added. If multiple schemas need to be configured, separate them with commas (,).

Example: currentSchema=schema_a,"schema-b","schema/c"

Property type: string

Default value: If this parameter is not set, the default schema is the username used for the connection.

loadBalanceHosts

Specifies whether to enable the load balancing function.

Property type: Boolean

Value range:

• true: The shuffle algorithm is used to randomly select a host from the candidates to establish a connection.
• false: Multiple hosts specified in the URL are connected in sequence.

Default value: false

autoBalance

Specifies a load balancing policy.

Property type: string

Value range:

• If this parameter is set to true, balance, or roundrobin, the JDBC load balancing function is enabled to balance multiple connections of an application to each CN available in the database cluster.

  Example:

  jdbc:opengauss://host1:port1,host2:port2/database?autoBalance=true

  JDBC periodically updates the list of available CNs in the entire cluster (data IP addresses of hosts in the CN list). The update interval can be configured using the refreshCNIpListTime parameter. The default value is 10 seconds. For example, the obtained list is as follows:

  host1:port1,host2:port2,host3:port3,host4:port4

  When load balancing is enabled, host1 and host2 ensure high availability only when they are connected for the first time. Then, the driver selects available CNs from host1, host2, host3, and host4 in sequence to refresh the available CN list. New connections will use the round robin algorithm to select CNs from host1, host2, host3, and host4 for connection.

• If this parameter is set to priorityn, the JDBC-based load balancing function is enabled. Multiple connections of an application are balanced to the first n available CNs configured in the URL. When the first n CNs are unavailable, connections are randomly allocated to other available CNs in the database cluster. n is a positive integer and is less than the number of CNs configured in the URL.

  Example:

  jdbc:opengauss://host1:port1,host2:port2,host3:port3,host4:port4/database?autoBalance=priority2

  JDBC periodically obtains the list of all available CNs in the entire cluster.

  host1:port1,host2:port2,host3:port3,host4:port4,host5:port5,host6:port6

  host1 and host2 are in AZ1, and host3 and host4 are in AZ2. The driver preferentially selects host1 and host2 for load balancing. If both host1 and host2 are unavailable, the driver randomly selects a CN from host3, host4, host5, and host6 for connection.

• If this parameter is set to shuffle, JDBC random load balancing is enabled to randomly and evenly distribute multiple connections of the application to available CNs in the database cluster.

  Example:

  jdbc:opengauss://host1:port1,host2:port2,host3:port3/database?autoBalance=shuffle

  JDBC periodically obtains the list of all available CNs in the entire cluster.

  host1:port1,host2:port2,host3:port3,host4:port4

  host1, host2, and host3 ensure high availability only when they are connected for the first time. Later, they use the shuffle algorithm to randomly select a CN from the refreshed CN list for connection.

• If this parameter is set to specified, the JDBC load balancing function is enabled and connections are established only on nodes specified in the user URL.

  Example:

  jdbc:opengauss://host1:port1,host2:port2,host3:port3,host4:port4/database?autoBalance=specified&priorityServers=2

  JDBC identifies host1 and host2 as the nodes for establishing connections in the primary cluster, and identifies host3 and host4 as the nodes for establishing connections in the standby cluster. When a connection is set up, JDBC evenly distributes the connections to host1 and host2. If all the nodes (host1 and host2) in the primary cluster are faulty, JDBC does not attempt to connect to the remaining nodes. After a switchover, JDBC evenly distributes connections to host3 and host4. If all nodes (host3 and host4) in the standby cluster are faulty, JDBC does not attempt to connect to the remaining nodes.

• If this parameter is set to false, the JDBC load balancing and priority-based load balancing functions are disabled.

Default value: false

refreshCNIpListTime

Obtains the cache validity period of the CNs. During connection establishment, the CN status in the database cluster is checked and is reliable within the period specified by refreshCNIpListTime. After the period expires, the status becomes invalid. The IP address list of available CNs is obtained again during the next connection establishment.

Property type: integer

Unit: s

Value range: 1 to 9999

Default value: 10

Suggestion: Adjust the value based on service requirements and use it together with autoBalance.

hostRecheckSeconds

After JDBC attempts to connect to a host, the host status is saved: connection success or connection failure. This status is trusted within the period specified by hostRecheckSeconds. After the period expires, the status becomes invalid.

Property type: integer

Unit: s

Value range: 0 to 2147483647.

Default value: 10

Property type: string

Value range: disable, allow, prefer, require, verify-ca, and verify-full.

• disable: SSL connection is disabled.
• allow: If the database server requires SSL connection, SSL connection can be enabled. However, authenticity of the database server will not be verified.
• prefer: If the database supports SSL connection, SSL connection is preferred. However, authenticity of the database server will not be verified.
• require: The system only attempts to set up an SSL connection. It neither checks whether the server certificate is issued by a trusted CA, nor checks whether the host name of the server is the same as that in the certificate.
• verify-ca: The system attempts to set up an SSL connection and checks whether the server certificate is issued by a trusted CA.
• verify-full: The system attempts to set up an SSL connection, checks whether the server certificate is issued by a trusted CA, and checks whether the host name of the server is the same as that in the certificate.

Default value: No default value is provided. If this property is not set, the value require is used.

loginTimeout

Specifies the waiting time for establishing the database connection. When multiple IP addresses are configured in the URL, if the time for obtaining the connection exceeds the value of this parameter, the connection fails and the subsequent IP addresses are not tried.

The value of loginTimeout is related to connectTimeout and socketTimeoutInConnecting. The calculation formula is as follows: loginTimeout = (connectTimeout + Connection authentication time + Initialization statement execution time) x Number of nodes.

Property type: integer

Unit: s

Value range: 0 to 2147483647. The value 0 indicates that the timeout mechanism does not take effect.

Default value: 0

Suggestion: After this parameter is set, an asynchronous thread is started each time a connection is established. If there are a large number of connections, the pressure on the client may increase. You are advised to set it as follows: max(connectTimeout, socketTimeoutInConnecting) x Number of nodes. This prevents connection failures when the network is abnormal and the nth IP address is the IP address of the primary node. You can adjust it based on the actual service situation.

connectTimeout

Specifies the timeout interval for connecting to a server OS. If the time taken to connect to a server OS exceeds the value specified, the connection is interrupted. When multiple IP addresses are configured in the URL, this parameter indicates the timeout interval for connecting to a single IP address.

Property type: integer

Unit: s

Value range: 0 to 2147483647. The value 0 indicates that the timeout mechanism does not take effect.

Default value: 0

socketTimeout

Specifies the timeout period for a socket read operation. If the time taken to read data streams from a server exceeds the value specified, the connection is closed. If this parameter is not set, the client waits for a long time when the database process is abnormal. You are advised to set this parameter based on the SQL execution time acceptable to services.

Property type: integer

Unit: s

Value range: 0 to 2147483647. The value 0 indicates that the timeout mechanism does not take effect.

Property type: integer

Unit: s

Value range: 0 to 2147483647. The value 0 indicates that the timeout mechanism does not take effect.

Default value: 5

statementTimeout

Specifies the timeout interval for executing a statement in a connection. If the execution time of a statement exceeds this value, the statement execution is canceled.

Property type: integer

Unit: ms

Value range: 0 to 2147483647. The value 0 indicates that the timeout mechanism does not take effect.

Default value: 0

cancelSignalTimeout

Controls "connect timeout" and "socket timeout" of a cancel command, which may cause blocking. If the cancel command does not respond within the specified time, the connection is interrupted to reduce the occupation of client resources.

Property type: integer

Unit: s

Value range: 0 to 2147483647. The value 0 indicates that the timeout mechanism does not take effect.

Default value: 10

• false: If the close() method is not called, the corresponding Connection object will not be closed.

Default value: false

assumeMinServerVersion

Specifies the version of the server to be connected.

If the value of assumeMinServerVersion is greater than or equal to 9.0, the number of packets to be sent are reduced during connection establishment. The client does not send a request to set the floating point to 3 (that is, retain the original floating point 2).

Property type: string

Default value: No default value is provided.

Default value: on

Suggestion: If the service framework (such as hibernate) checks the return value during batch update, you can set this parameter to solve the problem.

fetchsize

Specifies the default fetchsize for statements in the created connection.

Specifies the number of rows fetched from ResultSet each time. It has the same function as defaultRowFetchSize. If fetchsize and defaultRowFetchSize are set at the same time, fetchsize prevails.

Property type: integer

Value range: 0 to 2147483647.

Default value: 0. It indicates that all results are obtained from the database at a time.

Suggestion: You are advised to set this parameter based on the amount of data queried by services and the memory of the client. When setting fetchsize, disable automatic commit (set autocommit to false). Otherwise, the setting of fetchsize does not take effect.
