All parameters are optional. A brief description of each parameter
follows:
- user: the name of the user to connect to (default: None)
- proxy_user: the name of the proxy user to connect to. If this value
is not specified, it will be parsed out of user if user is in the
form "user[proxy_user]" (default: None)
- password: the password for the user (default: None)
- newpassword: the new password for the user. The new password will
take effect immediately upon a successful connection to the database
(default: None)
- wallet_password: the password to use to decrypt the wallet, if it is
encrypted. This value is only used in thin mode (default: None)
- access_token: expected to be a string or a 2-tuple or a callable. If
it is a string, it specifies an Azure AD OAuth2 token used for Open
Authorization (OAuth 2.0) token based authentication. If it is a
2-tuple, it specifies the token and private key strings used for
Oracle Cloud Infrastructure (OCI) Identity and Access Management
(IAM) token based authentication. If it is a callable, it returns
either a string or a 2-tuple used for OAuth 2.0 or OCI IAM token
based authentication and is useful when the pool needs to expand and
create new connections but the current authentication token has
expired (default: None)
- host: the name or IP address of the machine hosting the database or
the database listener (default: None)
- port: the port number on which the database listener is listening
(default: 1521)
- protocol: one of the strings "tcp" or "tcps" indicating whether to
use unencrypted network traffic or encrypted network traffic (TLS)
(default: "tcp")
- https_proxy: the name or IP address of a proxy host to use for
tunneling secure connections (default: None)
- https_proxy_port: the port on which to communicate with the proxy
host (default: 0)
- service_name: the service name of the database (default: None)
- instance_name: the instance name of the database (default: None)
- sid: the system identifier (SID) of the database. Note using a
service_name instead is recommended (default: None)
- server_type: the type of server connection that should be
established. If specified, it should be one of "dedicated", "shared"
or "pooled" (default: None)
- cclass: connection class to use for Database Resident Connection
Pooling (DRCP) (default: None)
- purity: purity to use for Database Resident Connection Pooling (DRCP)
(default: oracledb.PURITY_DEFAULT)
- expire_time: an integer indicating the number of minutes between the
sending of keepalive probes. If this parameter is set to a value
greater than zero it enables keepalive (default: 0)
- retry_count: the number of times that a connection attempt should be
retried before the attempt is terminated (default: 0)
- retry_delay: the number of seconds to wait before making a new
connection attempt (default: 1)
- tcp_connect_timeout: a float indicating the maximum number of seconds
to wait for establishing a connection to the database host (default:
20.0)
- ssl_server_dn_match: boolean indicating whether the server
certificate distinguished name (DN) should be matched in addition to
the regular certificate verification that is performed. Note that if
the ssl_server_cert_dn parameter is not privided, host name matching
is performed instead (default: True)
- ssl_server_cert_dn: the distinguished name (DN) which should be
matched with the server. This value is ignored if the
ssl_server_dn_match parameter is not set to the value True. If
specified this value is used for any verfication. Otherwise the
hostname will be used. (default: None)
- wallet_location: the directory where the wallet can be found. In thin
mode this must be the directory containing the PEM-encoded wallet
file ewallet.pem. In thick mode this must be the directory containing
the file cwallet.sso (default: None)
- events: boolean specifying whether events mode should be enabled.
This value is only used in thick mode and is needed for continuous
query notification and high availability event notifications
(default: False)
- externalauth: a boolean indicating whether to use external
authentication (default: False)
- mode: authorization mode to use. For example
oracledb.AUTH_MODE_SYSDBA (default: oracledb.AUTH_MODE_DEFAULT)
- disable_oob: boolean indicating whether out-of-band breaks should be
disabled. This value is only used in thin mode. It has no effect on
Windows which does not support this functionality (default: False)
- stmtcachesize: identifies the initial size of the statement cache
(default: oracledb.defaults.stmtcachesize)
- edition: edition to use for the connection. This parameter cannot be
used simultaneously with the cclass parameter (default: None)
- tag: identifies the type of connection that should be returned from a
pool. This value is only used in thick mode (default: None)
- matchanytag: boolean specifying whether any tag can be used when
acquiring a connection from the pool. This value is only used in
thick mode. (default: False)
- config_dir: directory in which the optional tnsnames.ora
configuration file is located. This value is only used in thin mode.
For thick mode use the config_dir parameter of init_oracle_client()
(default: oracledb.defaults.config_dir)
- appcontext: application context used by the connection. It should be
a list of 3-tuples (namespace, name, value) and each entry in the
tuple should be a string. This value is only used in thick mode
(default: None)
- shardingkey: a list of strings, numbers, bytes or dates that identify
the database shard to connect to. This value is only used in thick
mode (default: None)
- supershardingkey: a list of strings, numbers, bytes or dates that
identify the database shard to connect to. This value is only used in
thick mode (default: None)
- debug_jdwp: a string with the format "host=<host>;port=<port>" that
specifies the host and port of the PL/SQL debugger. This value is
only used in thin mode. For thick mode set the ORA_DEBUG_JDWP
environment variable (default: None)
- connection_id_prefix: an application specific prefix that is added to
the connection identifier used for tracing (default: None)
- ssl_context: an SSLContext object used for connecting to the database
using TLS. This SSL context will be modified to include the private
key or any certificates found in a separately supplied wallet. This
parameter should only be specified if the default SSLContext object
cannot be used (default: None)
- sdu: the requested size of the Session Data Unit (SDU), in bytes. The
value tunes internal buffers used for communication to the database.
Bigger values can increase throughput for large queries or bulk data
loads, but at the cost of higher memory use. The SDU size that will
actually be used is negotiated down to the lower of this value and
the database network SDU configuration value (default: 8192)
- pool_boundary: one of the values "statement" or "transaction"
indicating when pooled DRCP connections can be returned to the pool.
This requires the use of DRCP with Oracle Database 23.4 or higher
(default: None)
- use_tcp_fast_open: boolean indicating whether to use TCP fast open.
This is an Oracle Autonomous Database Serverless (ADB-S) specific
property for clients connecting from within OCI Cloud network. Please
refer to the ADB-S documentation for more information (default:
False)
- ssl_version: one of the values ssl.TLSVersion.TLSv1_2 or
ssl.TLSVersion.TLSv1_3 indicating which TLS version to use (default:
None)
- program: the name of the executable program or application connected
to the Oracle Database (default: oracledb.defaults.program)
- machine: the machine name of the client connecting to the Oracle
Database (default: oracledb.defaults.machine)
- terminal: the terminal identifier from which the connection
originates (default: oracledb.defaults.terminal)
- osuser: the operating system user that initiates the database
connection (default: oracledb.defaults.osuser)
- driver_name: the driver name used by the client to connect to the
Oracle Database (default: oracledb.defaults.driver_name)
- use_sni: boolean indicating whether to use the TLS SNI extension to
bypass the second TLS neogiation that would otherwise be required
(default: False)
- thick_mode_dsn_passthrough: boolean indicating whether to pass the
connect string to the Oracle Client libraries unchanged without
parsing by the driver. Setting this to False makes thick and thin
mode applications behave similarly regarding connection string
parameter handling and locating any optional tnsnames.ora
configuration file (default:
oracledb.defaults.thick_mode_dsn_passthrough)
- extra_auth_params: a dictionary containing configuration parameters
necessary for Oracle Database authentication using plugins, such as
the Azure and OCI cloud-native authentication plugins (default: None)
- handle: an integer representing a pointer to a valid service context
handle. This value is only used in thick mode. It should be used with
extreme caution (default: 0)

All parameters are optional. A brief description of each parameter
follows:
- user: the name of the user to connect to
- proxy_user: the name of the proxy user to connect to. If this value
is not specified, it will be parsed out of user if user is in the
form "user[proxy_user]"
- password: the password for the user
- newpassword: the new password for the user. The new password will
take effect immediately upon a successful connection to the database
- wallet_password: the password to use to decrypt the wallet, if it is
encrypted. This value is only used in thin mode
- access_token: expected to be a string or a 2-tuple or a callable. If
it is a string, it specifies an Azure AD OAuth2 token used for Open
Authorization (OAuth 2.0) token based authentication. If it is a
2-tuple, it specifies the token and private key strings used for
Oracle Cloud Infrastructure (OCI) Identity and Access Management
(IAM) token based authentication. If it is a callable, it returns
either a string or a 2-tuple used for OAuth 2.0 or OCI IAM token
based authentication and is useful when the pool needs to expand and
create new connections but the current authentication token has
expired
- host: the name or IP address of the machine hosting the database or
the database listener
- port: the port number on which the database listener is listening
- protocol: one of the strings "tcp" or "tcps" indicating whether to
use unencrypted network traffic or encrypted network traffic (TLS)
- https_proxy: the name or IP address of a proxy host to use for
tunneling secure connections
- https_proxy_port: the port on which to communicate with the proxy
host
- service_name: the service name of the database
- instance_name: the instance name of the database
- sid: the system identifier (SID) of the database. Note using a
service_name instead is recommended
- server_type: the type of server connection that should be
established. If specified, it should be one of "dedicated", "shared"
or "pooled"
- cclass: connection class to use for Database Resident Connection
Pooling (DRCP)
- purity: purity to use for Database Resident Connection Pooling (DRCP)
- expire_time: an integer indicating the number of minutes between the
sending of keepalive probes. If this parameter is set to a value
greater than zero it enables keepalive
- retry_count: the number of times that a connection attempt should be
retried before the attempt is terminated
- retry_delay: the number of seconds to wait before making a new
connection attempt
- tcp_connect_timeout: a float indicating the maximum number of seconds
to wait for establishing a connection to the database host
- ssl_server_dn_match: boolean indicating whether the server
certificate distinguished name (DN) should be matched in addition to
the regular certificate verification that is performed. Note that if
the ssl_server_cert_dn parameter is not privided, host name matching
is performed instead
- ssl_server_cert_dn: the distinguished name (DN) which should be
matched with the server. This value is ignored if the
ssl_server_dn_match parameter is not set to the value True. If
specified this value is used for any verfication. Otherwise the
hostname will be used.
- wallet_location: the directory where the wallet can be found. In thin
mode this must be the directory containing the PEM-encoded wallet
file ewallet.pem. In thick mode this must be the directory containing
the file cwallet.sso
- events: boolean specifying whether events mode should be enabled.
This value is only used in thick mode and is needed for continuous
query notification and high availability event notifications
- externalauth: a boolean indicating whether to use external
authentication
- mode: authorization mode to use. For example
oracledb.AUTH_MODE_SYSDBA
- disable_oob: boolean indicating whether out-of-band breaks should be
disabled. This value is only used in thin mode. It has no effect on
Windows which does not support this functionality
- stmtcachesize: identifies the initial size of the statement cache
- edition: edition to use for the connection. This parameter cannot be
used simultaneously with the cclass parameter
- tag: identifies the type of connection that should be returned from a
pool. This value is only used in thick mode
- matchanytag: boolean specifying whether any tag can be used when
acquiring a connection from the pool. This value is only used in
thick mode.
- config_dir: directory in which the optional tnsnames.ora
configuration file is located. This value is only used in thin mode.
For thick mode use the config_dir parameter of init_oracle_client()
- appcontext: application context used by the connection. It should be
a list of 3-tuples (namespace, name, value) and each entry in the
tuple should be a string. This value is only used in thick mode
- shardingkey: a list of strings, numbers, bytes or dates that identify
the database shard to connect to. This value is only used in thick
mode
- supershardingkey: a list of strings, numbers, bytes or dates that
identify the database shard to connect to. This value is only used in
thick mode
- debug_jdwp: a string with the format "host=<host>;port=<port>" that
specifies the host and port of the PL/SQL debugger. This value is
only used in thin mode. For thick mode set the ORA_DEBUG_JDWP
environment variable
- connection_id_prefix: an application specific prefix that is added to
the connection identifier used for tracing
- ssl_context: an SSLContext object used for connecting to the database
using TLS. This SSL context will be modified to include the private
key or any certificates found in a separately supplied wallet. This
parameter should only be specified if the default SSLContext object
cannot be used
- sdu: the requested size of the Session Data Unit (SDU), in bytes. The
value tunes internal buffers used for communication to the database.
Bigger values can increase throughput for large queries or bulk data
loads, but at the cost of higher memory use. The SDU size that will
actually be used is negotiated down to the lower of this value and
the database network SDU configuration value
- pool_boundary: one of the values "statement" or "transaction"
indicating when pooled DRCP connections can be returned to the pool.
This requires the use of DRCP with Oracle Database 23.4 or higher
- use_tcp_fast_open: boolean indicating whether to use TCP fast open.
This is an Oracle Autonomous Database Serverless (ADB-S) specific
property for clients connecting from within OCI Cloud network. Please
refer to the ADB-S documentation for more information
- ssl_version: one of the values ssl.TLSVersion.TLSv1_2 or
ssl.TLSVersion.TLSv1_3 indicating which TLS version to use
- program: the name of the executable program or application connected
to the Oracle Database
- machine: the machine name of the client connecting to the Oracle
Database
- terminal: the terminal identifier from which the connection
originates
- osuser: the operating system user that initiates the database
connection
- driver_name: the driver name used by the client to connect to the
Oracle Database
- use_sni: boolean indicating whether to use the TLS SNI extension to
bypass the second TLS neogiation that would otherwise be required
- thick_mode_dsn_passthrough: boolean indicating whether to pass the
connect string to the Oracle Client libraries unchanged without
parsing by the driver. Setting this to False makes thick and thin
mode applications behave similarly regarding connection string
parameter handling and locating any optional tnsnames.ora
configuration file
- extra_auth_params: a dictionary containing configuration parameters
necessary for Oracle Database authentication using plugins, such as
the Azure and OCI cloud-native authentication plugins
- handle: an integer representing a pointer to a valid service context
handle. This value is only used in thick mode. It should be used with
extreme caution
