Column Datatype NULL Description

SERVICE_ID

NUMBER

Unique ID for the service

NAME

VARCHAR2(64)

Name describing the workload

NAME_HASH

NUMBER

Hash of the short name for the service

NETWORK_NAME

VARCHAR2(512)

Network name used to connect to the service

CREATION_DATE

DATE

Date the service was created

CREATION_DATE_HASH

NUMBER

Hash of the creation date

FAILOVER_METHOD

VARCHAR2(64)

TAF only for compatibility - BASIC or NONE

FAILOVER_TYPE

VARCHAR2(64)

For Application Continuity for Java, TRANSACTION. For TAF, SESSION or SELECT.

FAILOVER_RETRIES

NUMBER(10)

For Application Continuity and TAF, when reconnecting after a failure, number of attempts to re-connect per incident

FAILOVER_DELAY

NUMBER(10)

For Application Continuity and TAF, when reconnecting after a failure, delay between each connection retry (in seconds)

MIN_CARDINALITY

NUMBER

Reserved for internal use

MAX_CARDINALITY

NUMBER

Reserved for internal use

GOAL

VARCHAR2(12)

Runtime Load Balancing Goal being used to create run-time load balancing and connection load balancing advice:

  • NONE

  • SERVICE_TIME - Connections are balanced by response time

  • THROUGHPUT - Connections are balanced by throughput

DTP

VARCHAR2(1)

DTP (distributed transaction processing) enforces all sessions for a service at one instance. This is a requirement for XA before 11g, and is a requirement if resuming and suspending the same XA branch.

ENABLED

VARCHAR2(3)

Reserved for internal use

AQ_HA_NOTIFICATIONS

VARCHAR2(3)

To enable FAN for OCI connections, set AQ HA Notifications to True. For Oracle Database 12c, FAN uses ONS (Oracle Notification Service)

CLB_GOAL

VARCHAR2(5)

Connection load balancing goal. When using run-time load balancing, GOAL=SERVICE_TIME or THROUGHPUT, set to SHORT. For a session count per service only, use LONG.

EDITION

VARCHAR2(128)

A non-NULL value specifies the initial session edition for subsequent database connections that use the service and do not specify an edition. A NULL value has no effect.

COMMIT_OUTCOME

VARCHAR2(3)

This attribute is used for Transaction Guard. When COMMIT_OUTCOME is set to TRUE, Transaction Guard manages the commit status for all supported transaction types. The attribute is on a per session basis and is set at connect time.

When the attribute is enabled:

  • The outcome of a COMMIT transaction is known. If there is an outage, the application can use DBMS_APP_CONT.GET_LTXID_OUTCOME to return a reliable status for the last in-flight work.

  • A logical transaction ID (LTXID) is set for each user session at login and at each successful commit.

See Also: For information about preserving the commit outcome, see Oracle Database Development Guide. For information about logical transaction IDs, see Oracle Database Development Guide.

RETENTION_TIMEOUT

NUMBER

For Transaction Guard (COMMIT_OUTCOME set to TRUE), this parameter determines the amount of time (in seconds) that the commit outcome is retained in the database

REPLAY_INITIATION_TIMEOUT

NUMBER

For Application Continuity, indicates a time period (in seconds) after which the request will not be replayed. The time period starts at the first request submission.

The default value is 300 seconds, which is 5 minutes.

SESSION_STATE_CONSISTENCY

VARCHAR2(128)

Describes how non-transactional is changed during a request. This parameter is considered only if failover_type is set to TRANSACTION for Application Continuity. Examples of session state are NLS settings, optimizer preferences, event settings, PL/SQL global variables, temporary tables, advanced queues, LOBs and result cache. If non-transactional values change after the request starts, the default value of DYNAMIC should be set. Almost all applications should use DYNAMIC mode. If you are unsure, use DYNAMIC mode.

GLOBAL_SERVICE

VARCHAR2(3)

Indicates whether the service is global. A global service is managed by Global Data Services (GDS) and can be provided by multiple databases that contain replicated data. Possible values:

  • YES: Indicates the service is global

  • NO: Indicates the service is not global

This attribute is set when using GDS. It cannot be set by a user.

PDB

VARCHAR2(128)

Name of a PDB associated with a given service. Will contain NULL for a non-CDB or if the service is not associated with a PDB (that is, connecting to a CDB using this service will cause a user to connect to the root.)

When managing services for a PDB, use SRVCTL for Oracle RAC and Oracle RAC One Node databases, or connect to that PDB if it is a single instance (not RAC). The PDB attribute shows which PDB has the service. It cannot be set or modified explicitly.

SQL_TRANSLATION_PROFILE

VARCHAR2(261)

A non-NULL value specifies the initial SQL translation profile for subsequent database connections that use the service and do not specify a SQL translation profile. A NULL value has no effect.

MAX_LAG_TIME

VARCHAR2(128)

The maximum replication lag (in seconds) that is acceptable for a data replica to be used for providing the database service. Can only be specified for global services using the Global Data Services (GDS) interfaces. It is not supported to change this value at local databases.

GSM_FLAGS

NUMBER

Flags specific to Global Data Services (GDS). Can only be specified for global services using the GDS interfaces. It is not supported to change these values at local databases.

PQ_SVC

VARCHAR2(64)

Name of the associated parallel query rim service

STOP_OPTION

VARCHAR2(13)

Stop option for sessions of this service for planned maintenance

FAILOVER_RESTORE

VARCHAR2(6)

Indicates whether sessions recover their commonly used session state (like NLS, schema) when they are failed over with TAF

DRAIN_TIMEOUT

NUMBER

Number of seconds to wait for sessions to be drained

TABLE_FAMILY_ID

NUMBER

Sharded table family ID associated with the service
