Patent Application
20120260246
The present invention relates generally to software application installation on a computer in a computer system, and more specifically, to installation of a software application as two or more packages for efficient sharing in a computer system.
Typically, software installation at a target computer in a computer system includes installing a software application contained in a single software package at the target computer. The installation process includes placing the software application binary or text files in a particular location in the target computer and registering or modifying existing files in the target computer. The installed software package at the target computer may be different than the installed software package at other computers in the computer system because of the modification of the software application files during installation (e.g. /etc/passwd). The target computer installed with the software application requires storage capability to store the entire software package. Additionally, if the target computer is provided with the software application from a server in the computer system, the computer system requires sufficient network bandwidth to receive the software package from the server.
A software application may also be installed at the target computer via a z/OS minidisk or the software application package may not be installed at the target computer but instead may be shared among computers in a computer network having a distributed file system (or NFS sharing). These modes of software application used by a target computer do not change/modify the target computer's base Operating System installation, or other application files, and may not update the RPM database.
According to one embodiment of the present invention, a software installation method may include installing at a server in a computer system a first files package including computer program files for a first software application, the computer system including at least a first computer installed with a first configuration package, the first configuration package including files necessary to configure and register the first software application, receiving a request at the server from the first computer for access to the first files package and making the first files package available for use by the first computer. The software installation method may further include receiving a request at the server from a second computer in the computer system for access to the first files package, the second computer installed with the first configuration package, and making the first files package available for use by the second computer.
In another embodiment of the present invention, a software installation method may include installing a first configuration package on a first computer in a computer system, the first configuration package including files necessary to configure and register a first software program, sending from the first computer in response to a user command a request to a server in the computer system for access to a first files package installed at the server, the first files package including computer program files for the first software program; and accessing by the first computer the first files package.
In yet another embodiment of the present invention, a computer program product for software installation may include at least one computer readable storage medium having computer readable program code embodied therewith. When read by a processor, the computer readable program code may be configured to install in a memory a first files package, the first files package including computer program files for a first software application, receive a request from a first computer in a computer system coupled to the processor for access to the first files package, the first computer installed with a first configuration package including files necessary to configure and register the first software application, and make the first files package available for use by the first computer.
In yet another embodiment of the present invention, a first computer may include a processor, a memory and a software installation program. The software installation program may include a plurality of instructions stored in the memory that are executed by the processor to install a first files package including computer program files for a first software application, receive a request from a second computer for access to the first files package, the second computer being installed with a first configuration package including files necessary to configure and register the first software application, and make the first files package available for use by the second computer. The plurality of instructions may further include instructions that are executed by the processor to receive a request from a third computer for access to the first files package, the third computer being installed with the first configuration package, and make the first files package available for use by the third computer.
As will be appreciated by one skilled in the art, aspects of the present invention may be embodied as a system, method or computer program product. Accordingly, aspects of the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, aspects of the present invention may take the form of a computer program product embodied in one or more computer readable medium(s) having computer readable program code embodied thereon.

With reference now to the figures and in particular with reference to
In the depicted example, a server 104 and a server 106 may connect to network 102 along with a storage unit 108. In addition, a first client computer 110, a second client computer 112, and a third client computer 114 may connect to network 102. Client computers 110, 112, and 114 may be, for example, personal computers or network computers. In the depicted example, server 104 may provide data, such as boot files, operating system images, and/or software applications to client computers 110, 112, and 114. Client computers 110, 112, and 114 are clients to server 104 in this example. Computer system 100 may include additional servers, clients, and other devices not shown, or may include fewer devices than those shown.
In the depicted example, network 102 may be or may include the Internet. Computer system 100 also may be implemented with a number of different types of networks, such as for example, an intranet, a local area network (LAN), or a wide area network (WAN).
A first software application may include two software packages, for example a first files package and a first configuration package, each of which may be installed on separate devices within computer system 100. For example, the first files package may be installed at server 104 and the first configuration package may be installed at one or more of client computers 110, 112 and/or 114. Server 104 may provide one or more of client computers 110, 112 and/or 114 access to the first files package. It should be appreciated that in other embodiments, the first software application may include more than two software packages. Additionally and/or alternatively, one or all of the software packages may be installed on multiple devices in the computer system 100. Each package may also include one or more sub-packages that when combined form the files package or the configuration package.
The first files package may include all of the files necessary for operation of the first software application and/or file placement. The first configuration package may include all of the tools/scripts necessary to configure and register the first software application so that the first software application may be used by the client computer. In some embodiments, the first configuration package may include everything except for file placement. The first configuration package may be smaller or “thinner” than the first files package.
For example, the first configuration package may include:
1. Any symbolic links that are needed in /bin or /usr/bin etc.;
2. Updates to a database that shows what applications are installed;
3. Simple additions to existing files. For example, adding user peripheral or network devices, such as adding “canonprinter” to /etc/passwd for a printer;
4. Scripts that change some files in a root file system;
5. Code for starting services like /etc/init.d/<service>;
6. Node/guest specific configuration files.
The first files package and the first configuration package may be run and/or installed at separate devices in computer system 100 at different times. However, the first software application may not be useable by a client computer without access to or installation of both the first files package and the first configuration package. For example, the first software application may not be useable by a client computer if one of the following conditions are not met:
1) the client computer does not have the first configuration package installed; or
2) the client computer is not provided access to the first files package installed at a server.
As noted above, one or all of client computers 110, 112 and/or 114 may have the first configuration packaged stored and/or installed. The first files package may be maintained and/or installed at server 104. Server 104 may provide access to the first files package to one or all of client computers 110, 112, and/or 114 via network 102 by making the first files package available for use by the client computer from whom the request for access is received. A client computer having both the first configuration package installed and access to the first files package is able to use the first software application.
For example, first client computer 110 and second client computer 112 may each have the first configuration package installed, however first client computer 110 and second client computer 112 may not use the first software application without access to the first files package. Access to the first files package may be provided by server 104. A request for access to the first files package may be sent from first client computer 110 in response to a user command and may be received at server 104. In response to the request, server 104 may make the first files package available for use by first client computer 110. First client computer 110 may then access the first files package and use the first software application.
Additionally and/or alternatively, a request for access to the first files package may be sent from second client computer 112 in response to a user command and may be received at server 104. In response to the request, server 104 may additionally make the first files package available for use by second client computer 112. Second client computer 112 may then access the first files package and use the first software application.
Accordingly, the first files package installed at server 104 may be efficiently shared among devices in computer system 100, here first and second client computers 110, 112. Furthermore, the storage requirements of first and second client computers 110, 112 and the bandwidth used by first and second client computers 110, 112 may be reduced because first and second client computers 110, 112 are not required to install first files package. Additionally, the time required to install the first configuration package may be less than the time required to install the full software application and/or the time required to remove the first configuration package may be less than the time required to remove the full software application.
A second software application may include two or more software packages, such as a second files package and a second configuration package, each of which may be installed on separated devices in computer system 100. For example, the second files package may be installed at server 104 and the second configuration package may be installed at one or more client computers 110, 112 and/or 114. Server 104 may provide one or more client computers 110, 112 and/or 114 access to the second files package.
The second files package may include all of the files necessary for operation of the second software application and/or file placement. The second configuration package may include all of the tools/scripts necessary to configure and register the second software application so that the second software application may be used by a client computer.
In one embodiment of the present disclosure, third client computer 114 may have the first configuration package and the second configuration package installed. As described above, server 104 may have the second files package installed, in addition to having the first files package installed. In response to a request for access from third client computer 114, server 104 may make the first files package and the second files package available for use by third client computer 114. Third client computer 114 may then access the first files package and the second files package and, accordingly, may use the first software application and the second software application.
In one example of sharing software images among different virtual guests in a virtual environment, the virtual environment may include three guests, guest1, guest2 and guest3, and a computer node that provisions the guests. Guest1 may require RHEL-base distribution and DB2 software. Guest2 may require RHEL-base distribution and WebSphere Application Software. Guest3 may require RHEL-base distribution, DB2 software and WebSphere Application Software.
The DB2 software may include a DB2 files package and a DB2 configuration package. The WebSphere Application Software may include a WebSphere Application Software files package and a WebSphere Application Software configuration package.
The compute node that provisions the guests may be loaded with an RHEL image, a DB2 files package image, a WebSphere Application Software files package image, as well as the DB2 configuration package and a WebSphere Application Software configuration package.
Guest1 may be booted with an RHEL and DB2 files package writeable snapshot image. The DB2 configuration package may be installed at guest1 after guest1 is booted. Guest 2 may be booted with an RHEL and WebSphere Application Software files package writeable snapshot image and the WebSphere Application Software configuration package may be installed after booting guest2. Guest3 may be booted with an RHEL, DB2 files package and WebSphere Application Software files package writeable snapshot image. The DB2 configuration package and WebSphere Application Software configuration package may be installed at Guest3.
In this example, there may be no need to create an image for each application stack as RHEL, the DB2 files package and the WebSphere Application Software files package have separate file sets and do not share any file. The individual application images may be combined using snapshot, unionFS or plain separate mount techniques. The application stack image may be constructed from the individual application files packages and the configuration packages may be run after booting the guest for the first time.
In a further example, one or more software applications may be shared among different systems in a network including a central server. The central server may be installed with software application files packages, such as the DB2 files package and the WebSphere Application Software files package. The software application files packages may be shared by the different systems over Network Files System (NFS) or other means. The software application configuration packages, such as the DB2 configuration package and the WebSphere Application Software configuration package, may be individually installed on each system. The install process for each system may be faster than installing a complete software application and disk space may be saved, as the software application files packages are shared from a central server. Additionally, the removal process for each system may be faster than removing a complete software application.
With reference now to
Processor unit 204 may serve to execute instructions for software that may be loaded into memory 206. Processor unit 204 may be a set of one or more processors or may be a multi-processor core, depending on the particular implementation. Further, processor unit 204 may be implemented using one or more heterogeneous processor systems in which a main processor is present with secondary processors on a single chip. As another illustrative example, processor unit 204 may be a symmetric multi-processor system containing multiple processors of the same type.
Memory 206 and persistent storage 208 are examples of storage devices. A storage device is any piece of hardware that is capable of storing information either on a temporary basis and/or a permanent basis. Memory 206, in these examples, may be, for example, a random access memory or any other suitable volatile or non-volatile storage device. Persistent storage 208 may take various forms depending on the particular implementation. For example, persistent storage 208 may contain one or more components or devices. For example, persistent storage 208 may be a hard drive, a flash memory, a rewritable optical disk, a rewritable magnetic tape, or some combination of the above. The media used by persistent storage 208 also may be removable. For example, a removable hard drive may be used for persistent storage 208.
Communications unit 210, in these examples, provides for communications with other data processing systems or devices. For example, communications unit 210 may be a network interface card. Communications unit 210 may provide communications through the use of either or both physical and wireless communications links.
Input/output unit 212 allows for input and output of data with other devices that may be connected to data processing system 200. For example, input/output unit 212 may provide a connection for user input through a keyboard and mouse. Further, input/output unit 212 may send output to a printer. Display 214 displays information to a user.
Instructions for the operating system and applications or programs are located on persistent storage 208. These instructions may be loaded into memory 206 for execution by processor unit 204. The processes of the different embodiments may be performed by processor unit 204 using computer implemented instructions, which may be located in a memory, such as memory 206. These instructions are referred to as program code, computer-usable program code, or computer-readable program code that may be read and executed by a processor in processor unit 204. The program code in the different embodiments may be embodied on different physical or tangible computer-readable media, such as memory 206 or persistent storage 208.
Program code 216 may be located in a functional form on a computer-readable media 218 that is selectively removable and may be loaded onto or transferred to data processing system 200 for execution by processor unit 204. Program code 216 and computer-readable media 218 form computer program product 220 in these examples. In one example, computer-readable media 218 may be in a tangible form, such as, for example, an optical or magnetic disc that is inserted or placed into a drive or other device that is part of persistent storage 208 for transfer onto a storage device, such as a hard drive that is part of persistent storage 208. In a tangible form, computer-readable media 218 also may take the form of a persistent storage, such as a hard drive, a thumb drive, or a flash memory that is connected to data processing system 200. The tangible form of computer-readable media 218 is also referred to as computer-recordable storage media. In some instances, computer-recordable media 218 may not be removable.
Alternatively, program code 216 may be transferred to data processing system 200 from computer-readable media 218 through a communications link to communications unit 210 and/or through a connection to input/output unit 212. The communications link and/or the connection may be physical or wireless in the illustrative examples. The computer-readable media also may take the form of non-tangible media, such as communications links or wireless transmissions containing the program code. The different components illustrated for data processing system 200 are not meant to provide architectural limitations to the manner in which different embodiments may be implemented. The different illustrative embodiments may be implemented in a data processing system including components in addition to or in place of those illustrated for data processing system 200. Other components shown in
In another example, a bus system may be used to implement communications fabric 202 and may be comprised of one or more buses, such as a system bus or an input/output bus. Of course, the bus system may be implemented using any suitable type of architecture that provides for a transfer of data between different components or devices attached to the bus system. Additionally, a communications unit may include one or more devices used to transmit and receive data, such as a modem or a network adapter. Further, a memory may be, for example, memory 206 or a cache such as found in an interface and memory controller hub that maybe present in communications fabric 202.
