摘要： A computer implemented method, a tangible computer storage medium, and a data processing system provide high availability support for virtual machines in a logical partitioned platform. A monitoring system detect a failure in the virtual machine. Partition management firmware then restarts the virtual machine in a consistency failover image node utilizing a consistency failover image. If a subsequent failure of the virtual machine is detected within a predetermined time, partition management firmware restarts the virtual machine in a boot failover image node utilizing a boot failover image.

摘要： A method, apparatus, and computer usable program product for automatic activation of roles is provided. When a user initiates an action, a set of roles needed for the action is identified. A set of roles assigned to the user is also identified. From the two sets of roles, all roles that are common to both sets are identified in a subset of roles. Roles in this subset are assigned to the user and are sufficient for the action. One or more roles from this subset of roles is selected for activation depending on system policies in effect. Selected roles are automatically activated without requiring any intervention from the user. Once the selected roles are activated, they can become inactive upon completion of the current action, or remain active for subsequent actions by the user during all or part of a user session. System policies can decide how the roles are selected for activation, and the duration of which the roles remain active once activated.

摘要： A method, programmed medium and system are provided for enabling a user to choose a user-preferred encryption type from among a plurality of encryption types listed in a user's Kerberos configuration file. During the ticket granting process in a Kerberos system, a user is requested to select a preferred encryption type to be used in the Kerberos communication from among encryption types contained in the user's Kerberos configuration file. The user-selected encryption type is then implemented for use in encrypting a session ticket (as well as generating the session key of user requested encryption type) for use by the user machine in communicating securely with an Kerberized application server when being communicated by that particular user. Thus, the system allows different users to simultaneously communicate with the same Kerberized application server using a supported encryption type of the user's own choice.
摘要翻译：提供了一种方法，编程介质和系统，用于使用户能够从用户的Kerberos配置文件中列出的多种加密类型中选择用户优选的加密类型。在Kerberos系统中的故障单授予过程中，请求用户从用户的Kerberos配置文件中包含的加密类型中选择要在Kerberos通信中使用的首选加密类型。用户选择的加密类型然后被实现以用于加密会话票据（以及生成用户请求的加密类型的会话密钥），以供用户机器在由特定的通信系统通信时与Kerberized应用服务器进行安全通信用户。因此，系统允许不同的用户使用用户自己选择的受支持的加密类型同时与相同的Kerberized应用服务器进行通信。

摘要： A file server receives a request from a client to mount an encrypted file system. The file server informs the client that the requested file system is encrypted and, in turn, receives a session ticket from the client that includes a security protocol mounting selection. The file server decrypts the client's user's encrypted private key, and then decrypts the requested encrypted file system using the private key. In turn, the file server sends the decrypted file system to the client over a secure channel, which is based upon the security protocol mounting selection. In one embodiment, a key distribution center server receives a request from the client for the client's user to access the encrypted file system at the file server. The key distribution center server retrieves an intermediate key; includes the intermediate key in a session ticket; and sends the session ticket to the client.

摘要： An encryption apparatus and method for providing an encrypted file system are provided. The encryption apparatus and method of the illustrative embodiments uses a combination of encryption methodologies so as to reduce the amount of decryption and re-encryption that is necessary to a file in the Encrypted File System in the event that the file needs to be modified. The encryption methodologies are interleaved, or alternated, with regard to each block of plaintext. In one illustrative embodiment, Plaintext Block Chaining (PBC) and Cipher Block Chaining (CBC) encryption methodologies are alternated for encrypting a sequence of blocks of data. The encryption of a block of plaintext is dependent upon the plaintext or a cipher generated for the plaintext of a previous block of data in the sequence of blocks of data so that the encryption is more secure than known Electronic Code Book encryption methodologies.

摘要： A computer implemented method, computer program product, and system for managing objects. Responsive to receiving a find-rule method, and a path-rule table, wherein the path-rule table contains a set of paths, wherein each path references an object, wherein a file system locates the object using the path, and wherein the object has at least one attribute not known to the file system, a path-rule table identifier is created. The path-rule table is associated with the path-rule table identifier to form an associated path-rule table. The find-rule method is associated with the path-rule table identifier to form an associated find-rule method. The path-rule table identifier, the associated path-rule table, and the associated find-rule method are stored. The path-rule table identifier is returned.
