Overview

Use this account type to connect Oracle Snaps with datasources that use Oracle Thin Dynamic data sources that use Oracle accounts. This account deals with the dynamically calculated values. You can specify the uses dynamic values and enables you to specify account properties as expressions referencing pipeline parameters. The values for dynamic accounts are not stored; hence, use them when requested.

Custom JDBC URL

String

Required if JDBC URL Source is User Provided. The JDBC URLs that you want to use to connect to your Oracle account.

Note

Use this option if you want to use complex JDBC URLs (involving multiple hosts and advanced options) to connect to your Oracle instance. For example, if you want to connect to Oracle DataGuard, you can enter a JDBC like the one below:

jdbc:oracle:thin:@(DESCRIPTION=(FAILOVER=on)(ADDRESS_LIST=(LOAD_BALANCE=on)(CONNECT_TIMEOUT=3)(RETRY_COUNT=3)(ADDRESS=(PROTOCOL=TCP)(HOST=host1)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=host2)(PORT=1522)))(CONNECT_DATA=(SERVICE_NAME=OracleTest)))

name	Oracle JDBC Driver Upgrade -Behavior Change
fallback	false

The Oracle JDBC Driver is migrated from ORAJDBC6 (11.2.0.4 version) to OJDBC10 JAR (19.20.0.0 version). However, you can specify a custom JBDC driver to use. Click the Database icon to upload an existing JAR file from the SLDB. If this property is left blank, a default JDBC driver is loaded.

falseBehavior Change

This JDBC driver upgrade has resulted in specific behavior changes within the Snap Pack. These changes include errors, status codes, and success and failure messages. The latest JDBC driver upgrade is backward-compatible.

Note
When you use the relative path for the JDBC JAR file in accounts across different projects, the pipelines fail with the `JAR FILE NOT FOUND` error. Therefore, you must use the absolute path for the JDBC JAR file to run your pipelines successfully.

Warning
Only v11.2.0.4.0 of a JDBC driver supports user-defined types.

Project Spaces/my_diagnostic_space/my_diagnostic /sqljdbc4-2.0.jar

JDBC Driver Class String Required. The name of the JBDC driver to use. oracle.jdbc.OracleDriver oracle.jdbc.OracleDriver

Database specifier type

String

Specify the database specifier type to use. The selected option decides which format of URL for JDBC is to be used internally. The valid options are:

SID: Uses the jdbc:oracle:thin@HOST:PORT:DBNAME format.
Service name: Uses the jdbc:oracle:thin@//HOST:PORT/DBNAME format.

Service name

SSL/ TCPS

String

Opt for or against connecting through SSL to the Oracle instance.

If selected, the following format of URL is used internally:

jdbc:oracle:thin@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCPS)(HOST=<HOST>)(PORT=<PORT>))(CONNECT_DATA=(<SID/ SERVICE_NAME>=<DATABASE_NAME>)))

Not Selected

Authentication method

Dropdown List

Choose the authentication method to use when connecting to Oracle. The available options are:

User ID and Password

Kerberos

Note

Kerberos authentication for Oracle supports both Windows and Linux-based databases and also supports Service account and User impersonation Kerberos authentication.
When the authentication method is Kerberos, for service account, you must leave the Username and Password fields empty and add the below property to the URL Properties:
oracle.net.kerberos5_cc_name = <Path to cache file>

User ID and Password

Kerberos

Kerberos config path

String/Expression

Appears when the Authentication method is Kerberos.

Specify the path to the Kerberos configuration file.

Note
Kerberos authentication for Oracle supports both Windows and Linux-based databases and also supports Service account and User impersonation Kerberos authentication.

Advanced properties N/A Specify advanced properties to connect to the database. N/A N/A

Auto commit

String

Opt for or against setting the auto-commit property for a database.

When selected, each of the batches is committed immediately after it is executed. If the Snap fails, only the batch being executed at that moment is rolled back.
When not selected, the Snap execution output is committed only after all the batches are executed. If the Snap fails, the entire transaction is rolled back, unless the Snap finds invalid input data before it sends the insert request to the server, and routes the error documents to the Error view.

Selected

Batch size

Integer

Required. Set the number of statements that the Snap must execute at a time.

Note
Select queries are not batched.

Warning
Using a large batch size could use up the JDBC placeholder limit of 2100.

50

100

Fetch size

Integer

Required. Set the number of rows that the Snap must fetch at a time when executing a query.

Warning
Large values could cause the server to run out of memory.

100

Max pool size Integer Required. Set the maximum number of connections that a pool must maintain at a time. 50 50

Max life time Integer Required. Set the maximum time (in minutes) of a connection in the pool. Ensure that the value you enter is a few seconds shorter than any database or infrastructure-imposed connection time limit. A value of 0 indicates an infinite lifetime, subject to the Idle Timeout value. An in-use connection is never retired. Connections are removed only after they are closed. 30 35

Idle Timeout Integer Required. Set the maximum time maximum time (in seconds?) that a connection is allowed to sit idle in the pool. A value of 0 indicates that idle connections are never removed from the pool. 5 5

Checkout timeout

Integer

Required. Set the time in milliseconds to wait for a connection to be available when the pool is exhausted.

Zero waits forever.An exception is thrown after the wait time has expired

Info
If you provide 0, the Snap waits infinitely until the connection is available. Therefore, we recommend you not to specify 0 for Checkout Timeout.

10000

URL Properties N/A Specify input regarding URL properties. N/A N/A

URL property name String Name for the URL property. N/A Batch refresh time in seconds_Refresh_Time

URL property value N/A Value for the URL property. N/A 10
