#### Advanced Attributes

Table 299-2

Attribute Label | Description | Value Constraints
--- | --- | ---
Default GIOP Version | Specify the default minor GIOP version for IIOP messages. This attribute is useful for client orbs with broken GIOP 1.2 implementations. MBean: `weblogic.management. configuration.IIOPMBean` Attribute: `DefaultMinorVersion` | Minimum: 0 Maximum: 2 Default: 2 Configurable: yes
Transaction Mechanism | Specify whether IIOP should use the WebLogic-specific JTA to propagate transactions or the OMG-specified OTS. It is not possible to use both since it affects the wayr transactions are negotiated. MBean: `weblogic.management. configuration.IIOPMBean` Attribute: `TxMechanism` | Default: "OTS" Valid values: "OTS" "JTA" Configurable: yes
Default Char Codeset | Specify what codeset should be used for the default native character codeset. This is required to interoperate with some Orbs that do not do codeset negotiation, or do it incorrectly. Setting this to anything other than US-ASCII will cause failure against JDK 1.3.1 clients. MBean: `weblogic.management. configuration.IIOPMBean` Attribute: `DefaultCharCodeset` | Default: "US-ASCII" Valid values: "US-ASCII" "UTF-8" "ISO-8859-1" Configurable: yes
Default Wide Char Codeset | Specify what codeset should be used for the default native wide character codeset. This is required to interoperate with some Orbs that do not do codeset negotiation, or do it incorrectly. Setting this to anything other than UCS-2 will cause failure against JDK 1.3.1 clients. MBean: `weblogic.management. configuration.IIOPMBean` Attribute: `DefaultWideCharCodeset` | Default: "UCS-2" Valid values: "UCS-2" "UTF-16" "UTF-8" "UTF-16BE" "UTF-16LE"
Default IIOP Username | The default IIOP user. MBean: `weblogic.management. configuration.ServerMBean` Attribute: `DefaultIIOPUser` | Default: null
Default IIOP Password | The password for the default IIOP user. MBean: `weblogic.management. configuration.ServerMBean` Attribute: `DefaultIIOPPassword` | Default: null Encrypted: yes
