Stash is now known as Bitbucket Server.
See the

Unknown macro: {spacejump}

of this page, or visit the Bitbucket Server documentation home page.

This page describes how to connect Stash to a Oracle database. 

The overall process for using a Oracle database with Stash is:

  • Install Oracle where it is accessible to Stash.
  • Create a database and user on the Oracle server for Stash to use.
  • Install Stash on Windows, or on Linux or Mac. See Getting started.
  • 次のいずれかを実行します。
    • at Stash install time, run the Setup Wizard to connect Stash to the Oracle database, or
    • at a later time, migrate Stash to the Oracle database. See Using the Database Migration Wizard .

It is assumed here that you already have Oracle installed and running. For information about installing Oracle and creating Oracle databases, see the Oracle documentation pages. For the versions of Oracle supported by Stash see Supported platforms.



If you are migrating your data from the internal Stash database, back up the Stash home directory.

If you are migrating your Stash data from a different external database, back up that database by following the instructions provided by the database vendor before proceeding with these instructions.

See Data recovery and backups.

Create the Stash database

Before you can use Stash with Oracle, you must set up Oracle as follows:

  • Ensure that you have a database instance available for Stash (either create a new one or use an existing one)
    The character set of the database must be set to either AL32UTF8 or UTF8, to support storage of Unicode data as per the Oracle documentation.
    Note that it is important to the proper operation of Stash that the database store its data in a case-sensitive manner. By changing the values of the NLS_COMP and/or NLS_SORT variables, it is possible to cause Oracle to perform its searches in a case-insensitive manner. We therefore strongly recommend that those variables be left at their default values.
  • Create a user that Stash will connect as (e.g. stash). 
    (tick) Remember the database user name; it will be used to configure Stash's connection to the database in subsequent steps.
    (info) When you create a user in Oracle, a schema is automatically created.
    It is strongly recommended that you create a new database user for use by Stash rather than sharing one that is used by other applications or people.
  • Grant the Stash user connect and resource roles only. The connect role is required to set up a connection, while resource role is required to allow the user to create objects in its own schema.
  • Create a local all_objects view to the user's schema, so that there is no possibility that a table with the same name as one of the Stash tables in another schema will cause any conflicts.
  • Note that Stash requires the database to keep idle connections alive for at least 10 minutes. If the database is configured with less than a 10 minute connection timeout, there will be seemingly random connection errors

The format of the command to create a user in Oracle is:

  IDENTIFIED BY <password>
CREATE VIEW <user>.all_objects AS
  FROM sys.all_objects
  WHERE owner = upper('<user>');

Here is a simple example, using SQL*Plus, of how one might create a user called stash with password jdHyd6Sn21 in tablespace users, and grant the user a minimal set of privileges. When you run the command on your machine, remember to replace the user name, password and tablespace names with your own values.

CREATE VIEW stash.all_objects AS
  FROM sys.all_objects
  WHERE owner = upper('stash');

This creates an empty Oracle schema with the name stash, and a user that can log in from the host that Stash is running on and who has full access to the newly created schema. In particular, the user is allowed to create sessions and tables.

Stash will generally require about 25–30 connections to the database. The maximum number of connections is a configurable system property – see Database pool.

Connect Stash to the Oracle database

You can now connect Stash to the Oracle database, either:

  • when you run the Setup Wizard, at install time,
  • when you wish to migrate to Oracle, either from the embedded Stash database or from another external database.

When running the Setup Wizard at install time

  1. Select External at the 'Database' step.
  2. Select Oracle for Database Type.
  3. Complete the form. See the table below for details.
  4. Click Next, and follow the instructions in the Stash Setup Wizard.

When migrating to Oracle

  1. In the Stash administration area, click Database (under 'Settings').
  2. Click Migrate database.
  3. Select Oracle for Database Type.
  4. Complete the form. See the table below for details.
  5. Click Start Migration.

The host name or IP address of the computer running the Oracle server.

ポートThe TCP port with which Stash can connect to the database server. The default value is the default port that Oracle runs against. You can change that if you know the port that your Oracle instance is using.
データベース名The system identifier of the Oracle instance that Stash should connect to. Stash does not support connecting to Oracle servers which are using SIDs or TNS Alias to identify themselves; it requires the fully qualified Service Name instead.
Database usernameThe username that Stash should use to access the database.
データベース パスワードThe password that Stash should use to access the database.

Install the JDBC driver

This section is only relevant to some distributions of Stash, for example if you are running Stash via the Atlassian Plugin SDK, or have built Stash from source.

If the Oracle JDBC driver is not bundled with Stash, you will need to download and install the driver yourself.

  1. Download the appropriate JDBC driver from the Oracle download site.
  2. Copy the downloaded jar file to your <Stash home directory>/lib directory (for Stash 2.1 or later).
  3. Stop, then restart, Stash. see Starting and stopping Stash.
