Systems and methods for managing Software-as-a-Service (SaaS) provided by a virtual machine are described. The system may include a management application, and may receive a feature package from the virtual machine. The feature package may be associated with a function supported by the virtual machine. The system may integrate the feature package into the management application, and transmit a first command to the virtual machine for executing the function at the virtual machine. The first command may be generated by the management application based on the feature package.

Techniques for performing dynamic load balancing during distributed query processing are provided. In one embodiment, a first processing node in a plurality of processing nodes can execute an instance of a query operator, where the query operator is part of a query plan for a database query that is processed in a distributed manner by the plurality of processing nodes. The first processing node can further monitor its load level while the executing occurs. If the load level exceeds a threshold, the first processing node can split an amount of remaining work that is associated with the executing into a first portion and a second portion, determine state information for moving execution of the second portion from the first processing node to a second processing node, and save the state information to a distributed data store.

Dynamic load balancing during distributed query processing using query operator motion

Techniques for enabling fault tolerant distributed query processing are provided. In one embodiment, a first processing node in a plurality of processing nodes can execute an instance of a query operator, where the query operator is part of a query plan for a database query that is processed in a distributed manner by the plurality of processing nodes. The first processing node can further generate a snapshot of the instance of the query operator, where the snapshot includes state information usable for moving execution of the query operator from the first processing node to another processing node after a failure of the first processing node. The first processing node can then save the snapshot to a distributed data store.

In one embodiment, a computer system creates a first template VM that includes a first OS VMDK and a first software binary VMDK, and clones the first template VM to create a linked clone VM. The linked clone VM executes a guest OS by accessing the first OS VMDK and a software application by accessing the first software binary VMDK. The computer system further creates a second template VM that includes a second software binary VMDK, where the second software binary VMDK includes one or more upgrades to the software application that are not included in the first software binary VMDK. The computer system then detaches the first software binary VMDK from the linked clone VM and attaches the second software binary VMDK to the linked clone VM. The linked clone VM thereafter executes the software application by accessing the second software binary VMDK.

Techniques for performing virtual machine software upgrades using virtual disk swapping

Memory of a database management system (DBMS) that is running in a virtual or physical machine is managed using techniques that that reduce the effect of memory swaps on the performance of the physical or virtual machine. One such technique includes the steps of determining a swap rate while the database application is in an executing state, and decreasing the size of memory space available to the database application if the swap rate is above a threshold.

Dynamic database memory management according to swap rates

Memory of a database management system (DBMS) that is running in a virtual machine is managed using techniques that integrate DBMS memory management with virtual machine memory management. Because of the integration, the effectiveness of DBMS memory management is preserved even though the physical memory allocated to the virtual machine may change during runtime as a result of varying memory demands of other applications, e.g., instances of other virtual machines, running on the same host computer as the virtual machine.

A computer readable storage medium includes executable instructions to order a binary tree using primary values and selected secondary values required to resolve a position in the binary tree. The remaining secondary values are in a do not care state. A new primary value is compared to the primary value at the root node of the binary tree. If necessary, a new secondary value is compared to the secondary value at the root node to determine whether the new primary value and the new secondary value or the value at the root node should be placed in a sorted list.
