USER_ONLY_SECURITY

public static final short USER_ONLY_SECURITY

The source security mechanism to use when connecting to this data source.

Security mechanism options are:

• USER_ONLY_SECURITY
• CLEAR_TEXT_PASSWORD_SECURITY
• ENCRYPTED_PASSWORD_SECURITY
• ENCRYPTED_USER_AND_PASSWORD_SECURITY - both password and user are encrypted
• STRONG_PASSWORD_SUBSTITUTE_SECURITY

The default security mechanism is USER_ONLY SECURITY

If the application specifies a security mechanism then it will be the only one attempted. If the specified security mechanism is not supported by the conversation then an exception will be thrown and there will be no additional retries.

This property is currently only available for the DNC driver.

Both user and password need to be set for all security mechanism except USER_ONLY_SECURITY

getSecurityMechanism

public static short getSecurityMechanism(java.util.Properties properties)

Return security mechanism if it is set, else upgrade the security mechanism if possible and return the upgraded security mechanism

Parameters:

properties - Look in the properties if securityMechanism is set or not if set, return this security mechanism

Returns:

security mechanism

getUpgradedSecurityMechanism

public static short getUpgradedSecurityMechanism(java.lang.String password)

This method has logic to upgrade security mechanism to a better (more secure) one if it is possible. Currently derby server only has support for USRIDPWD, USRIDONL, EUSRIDPWD and USRSSBPWD (10.2+) - this method only considers these possibilities. USRIDPWD, EUSRIDPWD and USRSSBPWD require a password, USRIDONL is the only security mechanism which does not require password. 1. if password is not available, then security mechanism possible is USRIDONL 2. if password is available,then USRIDPWD is returned.

Parameters:

password - password argument

Returns:

upgraded security mechanism if possible

setCreateDatabase

public final void setCreateDatabase(java.lang.String create)

Set this property to create a new database. If this property is not set, the database (identified by databaseName) is assumed to be already existing.

Parameters:

create - if set to the string "create", this data source will try to create a new database of databaseName, or boot the database if one by that name already exists.

getCreateDatabase

public final java.lang.String getCreateDatabase()

Returns:

"create" if create is set, or null if not

setShutdownDatabase

public final void setShutdownDatabase(java.lang.String shutdown)

Set this property if one wishes to shutdown the database identified by databaseName.

Parameters:

shutdown - if set to the string "shutdown", this data source will shutdown the database if it is running.

getShutdownDatabase

public final java.lang.String getShutdownDatabase()

Returns:

setConnectionAttributes

public final void setConnectionAttributes(java.lang.String prop)

Set this property to pass in more Derby specific connection URL attributes.
Any attributes that can be set using a property of this DataSource implementation (e.g user, password) should not be set in connectionAttributes. Conflicting settings in connectionAttributes and properties of the DataSource will lead to unexpected behaviour.

Parameters:

prop - set to the list of Derby connection attributes separated by semi-colons. E.g., to specify an encryption bootPassword of "x8hhk2adf", and set upgrade to true, do the following:

             ds.setConnectionAttributes("bootPassword=x8hhk2adf;upgrade=true"); 

See Derby documentation for complete list.
