SWsoft Virtuozzo: maverick chaser


Four years ago, SWsoft, VMware and Connectix 3 in PC and PC Server platform of virtual machine technology can be said to be separate categories. After the two were with the EMS and the Microsoft acquisition, has also maintained an independent portal Swsoft looks fairly maverick. And it is heavy head in 2005, also introduced a unique Virtuozzo.




Virtuozzo's technology works by a single physical server to create multiple isolated Virtual Private Server (Virtual Private Server, VPS). The VPS share the system hardware, software licenses and management resources. In terms of its users and applications, each VPS platform operation and management of a separate host with exactly the same, because each VPS can be independently reset, and have their own Root access, users, IP addresses, memory , processes, files, applications, system libraries and configuration files.

Virtuozzo vs Microsoft Virtual Server 2005 and Xen, the advantages of its host operating system is no doubt lower requirement can support Linux Windows family and family, however, compared with Vmware, it is catch-up role. Virtuozzo to achieve the realization of the principle and function with the Sun Solaris Container is very similar to that in a Host OS on the division of a number of VPS (Sun called the Zone), in each VPS can run separate applications.

However commendable Virtuozzo management interface is simple, it's management console (VZMC) and Virtual Server 2005, as can be concentrated on the centralized management of all virtual objects. In VZMC, you can start, stop, restart all of the virtual server, and upload the local file (the specified target path), browse the disk, mount the hardware node folder, cancellation performance monitoring, management services and users to detect the event log through Remote Desktop to connect.

Since Virtuozzo is the main push of the client base of large enterprises and IDC operators, so SWsoft provides the template creation wizard, the wizard to create an application template provides two defined methods. The first method is called from the manual selection of data that requires you to define each individual within the template files and registry entries. This is indeed very powerful, but too complex and difficult to complete the work of ordinary users, it requires users to know exactly how the applications work.

The second method is called from the application selection data, which is a very simple way: Virtuozzo creates a temporary VPS, install the applications you need, then a different operation to infer what changes have taken place within the environment, and these Change write custom template, the last temporary VPS will be deleted. In this process, the user need to use command-line tool to manually add the new template to the hardware node, then it will appear in plate library, you can deploy it in any VPS.

Like with VMware and Microsoft, Swsoft also provides virtual machines from physical server to (P2V) migration tools to accelerate the migration operation, easing driver conflicts. In the Virtuozzo Windows 3.5.1 version, SWsoft introduced called VZP2V physical to virtual migration tools. Before migrating to virtual infrastructures, and other virtual machine, like, Virtuozzo need to install physical server migration assistant agent, but VZP2V allowed to know the administrator account and password in the conduct of the remote installation. To ensure maximum security, the whole operation will be completed through the SSH channel. In the standard 10/100MB LAN transfer a 4GB hard drive (no RAID configuration) of Windows Server 2003 server will take about 50 minutes.

mapgis basic knowledge and simple learning materials


1. Why are some laptop computers can not use the software MAPGIS dog?

In some notebook computers to install MAPGIS software, sometimes "the system can not find the dog MAPGIS software or software card" message, the problem is usually not caused by the parallel port mode selection, we can go to the COMS (the need to reboot the machine use "DEL" key or other health or F2 key to enter COMS) found "Parallel Port Mode" option to see its value is not [ECP], if not, be changed to [ECP], you can save out. This method in some brand desktops apply.

2. MAPGIS in the project, documents the relationship between the layers

MAPGIS management and engineering is used to describe the point, line, area, network, image file, it can be more than one point, line, area, network, image files.

Works, documents, layers of relationship is this: works include files (number of point, line, area, network, image files), file that contains layers, layer contains primitive.

3. How to create and use the engineering legend?

鈶?First, open the project file.

Operation in the project area 鈶?Right-click and select "New Project Legend."

鈶?In the Legend Type, select the type.

鈶?Enter the information in the legend the legend the name, descriptions and classification codes.

鈶?Click the "Legend parameters" enter the legend parameters.

鈶?use the "Add" button to add the selected pixel to the right of the list box; For changes can "edit" button or double-click the list box of the legend.
鈶?built and legend and click "OK" button will be prompted to save the file, you can save.

鈶?To use the Legend version, first associated with the legend, the project operator in the region right-click and select "files associated with the legend" use "Edit Legend File" button choose the right file and click "OK"; and then click the right health, select "Open Legend Plate" button.

With "Legend board" can avoid repeated access to the menu to modify the parameters, to improve efficiency, and ensure the accuracy of graphics.
4. Engineering legend in the use of classification codes and coding

(1) We set up category codes, you can realize: there are many files in the project case, elected to a legend, the system will automatically jump to the legend associated with the file and the file is set to the current work area, so we do pixel write it will automatically be in the file; also open in the legend panel display can be classified according to legend. Operation as follows:

鈶?In the project operation area, click right mouse button, select "Edit Project Legend", click "Category", type "classification codes" (between 0-255) and the category name. After all the input Click "OK" button.

鈶?Double-click the table in the legend of a legend, classification yards in the specified category code. All illustrations should be designated the appropriate classification code. Finished, click "OK" to save the exit (Note: a classification code may correspond to many legends).

鈶?In the project operation area, select a file, the file double-click the left mouse button shows a list of Department, and then change the classification code corresponding to the above classification code edited. All documents should have the appropriate classification code.

(2) set up codes, you can board in a non-legend "was fine mode" 銆攂oard in the legend to choose銆?by right under the code directly into the system will automatically jump to the legend on the corresponding code.

5. How to modify the legend version of primitive parameters?

Legend plate with the parameters to modify the pixel is very convenient. To modify the area as an example, open the Legend board, the editor in the area Select "Edit Area parameters", and then in the legend of the district board to select the correct legend; then click the work area (you can pull box to select multiple areas) to area can be modified.

6. Input line, how to ensure that the lines intersect is completely coincide?

We have tentatively called the bus line, input line, the cursor landed on the bus by "F12" key, the system pop-up "choices made line capture mode" dialog box, choose according to the needs of our capture method.

7. Primitive parameters of "transparency" mean?

Primitive parameters in the editing, point, line, area pixel has a transparent option, it is mainly in the printing works, do not select the option that output in the production of color separation, the pixel is "hollow" and , in the printing position misalignment, there will be "trapping" phenomenon; if this option is selected, that element of the plan is "not hollow", and in print may result in pixel color change. These two situations are relatively neutral in the use of the actual situation can only choose one.

8. Automatic cut line after the completion of why drawing big change?

MAPGIS during topology error check, will automatically make the value of the node node search radius adjustment. If the node search radius value is too large, then there will be more graphics changes. Solution: change the node search <= 0.1 (Lai Shan: set / set system parameters [node / cut search radius]).

9. Why are scanning raster file is opened in editing system will prompt memory or can not display correctly?

MAPGIS not support all of the raster file formats, it supports only binary, grayscale and color (RGB mode) of three TIF format raster files (*. TIF), and also requires its non-compressed (LZW is not selected) format. Generally speaking, an "open grating in the editing system files or memory prompts are not displayed correctly," This is a file format. Solution: open the grating in PHOTOSHOP file, then re-set its image mode can be. In setting its mode Note:

鈶?To set the 8-bit channel mode (Menu: Image / Mode [8-channel]).

鈶?Set the bitmap, grayscale, RGB (Menu: Image / Mode [bitmap], [Gray], [RGB]).
Note: in particular, can not be set to CMYK color map mode.

鈶?Save Image mode to meet the raster file, the note must be kept non-compressed format (menu: File / Save As). When the pop-up storage for the dialog box: [file] input file name; [stored as] to select TIFF (*. TIF; *. TIFF), click "save" it pops up a dialog box; [Byte order] selected IBM PC , LZW compression option to remove the front.

10. Why do sub-chart is always kept less than a sub-gallery?

鈶?View sub-library and system library directory is read-only status, should be removed if the read-only, can be changed to archived.
鈶?Remove the temporary file system library (in. TMP at the end).

鈶?system libraries to be occupied with other MAPGIS procedures. Quit all applications MAPGIS restart MAPGIS, just start a MAPGIS input editing system.

11. Why open sub-linear library or library, the library primitives looming?

Mainly because the operating system loads the software and the localization of some real-time monitoring software, such as "Rising anti-virus" software, Kingsoft, the Orient Express and so on. Methods: The application quit.

12. How to MAPGIS graphics into word in?

First Tap MAPGIS menu "Other -> OLE copy", then open the WORD application, tap the WORD "paste" menu. MAPGIS data is copied into a WORD document in.

Note: The first call to this function, need to Mapsee6x.exe (installation path programMapsee6x.exe) run time.

13. How to make spot color?

Into the "edit spot color", the system pop-up spot color editor panel, the user selects to edit a spot color, the editor of this special CMYK color visualization of the displayed concentration, then the user can scroll bars to adjust the CMYK, until satisfaction, click "save spot color" button you can save to disk. If users need to add a new spot color, press "Add Spot Color" button, then adjust the new spot color of CMYK, the satisfaction of archiving. If users need to remove a spot color, press the "reduction of spot color" button.

14. Print raster file which the printer should be used?

Use the "Print raster file" print, the system will pop up "output device settings" dialog box "output device" means your printer model, based on your printer you can select your appropriate model, as HP1050CP, HP3000CP, HP600CP can select the "HP DJ2000CP, HP DJ2500CP" option: CALCOMP plotter choose "HP DJ750C, HP DJ350C" option. "Use printer" is actually a port point, that the output of raster data can be selected print driver is sent to the corresponding device.

15. How to use TrueType fonts output PS or EPS files?

To use TrueType fonts, first of all, go to "System Settings" choose "to use TrueType fonts", the system will pop-up "MAPCAD, MAPGIS font configuration" window, a list of the top left corner of the window shows the current system installed the TrueType font, the upper right corner is the configuration of font sizes and font name. Selected on the left of a font, then select the right one the corresponding number, press the middle "鈫? key to correspond to the left; press "鈫? to empty the current position on the left of the font. If you use TrueType fonts as text output into a PS or EPS files, you need to set PS font name ", where, as long as users are using TrueType fonts in the RIP of the PS corresponding to the font name of the input can, in When PS or EPS output selected text by encoding the output.

16. Why graphic after graphic printout will enlarge?

Any one of a default printer has its output resolution when using MAPGIS raster processing, if the default printer rasterization resolution and output resolution is inconsistent, there will be graphics zoom in and out. Methods: check the printer default output resolution is the number, then when the grating raster processing of the printer resolution is set as the default output resolution. Note: Print raster file system default is the last raster processing parameters.

17. Using the "WINDOWS print" the primitives missing why?

Widows mainly due to the specific printer driver and printer hardware itself brought the memory size. Solution: The printer output can be set in the WINDOWS menu command, click the "Properties" dialog box, enter the property, and under a single graphical graphical Lai select "Use raster graphics', after the commencement of withdrawal can be determined.

18. Fly point there how do?

Complex graphics, due to various reasons (mainly to improper operation), the phenomenon caused by outliers. Fly point there, you can edit the input using "part of the save file" function to remove fly spots. Determine whether there is the phenomenon of flight points can be edited in the graphics subsystem in the window menu select reset the window to see it full screen graphics display; output subsystem can also edit the project document, in the circumstances under which the system automatically 1:1 Test format size, compared the size of the detected format is the same size and the actual format. If flying spot has been found in the project settings, hold down the Ctrl + mouse to move the location of graphics on the paper and reduce the actual size of the page to date.

19. Large graphic print graphics on how automatic increase?

For large graphics, we use grating output method. Raster file processing is complete, select the print raster files, the system pop-up "output device settings" dialog box, you should be packed in accordance with your plotter paper size settings in the "paper width" "length of paper." This way, when your paper size is smaller than raster format when, the system will automatically page.

20. Can the graphic form to image?

Can. In the graphic output subsystem, open the project file, "raster output" menu you can find the generated GIF, TIFF, JPEG images command. In the output image MSI project can be joined at the same time the output.

21. Why is PS or EPS output always appears "unable to open file aihead.Ps" prompt?

AIHEAD.PS the standard header files EPS files, including EPS header information. This situation occurs because the above: in your system library directory does not this file. Methods: MAPGIS install the system library directory AIHEAD.PS and AIHEAI.EPS file copy (.. MAPGIS61SLIB) to your system library directory can.

22. How fat spot color film?

Spot color hair color separation film output can be used, the system will generate various color separation files, the file name were the last character "1", "2", "3", "4", ... ..., corresponding to the first 4 files Four different color printing inks, where "1" indicates that the document printed using black ink, "2" for the blue, "3" magenta, "4" for yellow. If spot color, then to have more documents, "spot color 1" corresponds to the file name of the last character is "5", "spot color 2" corresponding to "6", and so on. You can use these files directly to the imagesetter output.
23. Why HP500 not printing raster files?

HP500 machines need to have HP-GL2 card support, and HP500 Standard models do not have this card, users need to be purchased separately.

24. In the output module, the file output processing, often says "illegal operation" or "a primitive error" message. How to deal with these error messages?

What happens in a prompt, usually pixel parameter is wrong, beyond the parameters of the system library. Method: You can start running tips in view the current pixel being processed number (address to the pixel number of the error, is certainly a problem of the pixel), and then open the input editing subsystem, where the pixel File Open (example: for the area where the document file), and finally, use "(the line, point) to edit" under "Edit the specified area (line or point)," View to a primitive parameter errors, check the color and other parameters Does the library have exceeded the system parameter values, if the line, check whether there are ancillary and auxiliary linear linear whether the auxiliary parameters, check and correct after the save, then re-export processing.

25. How to Successful MAPGIS graphics data into graphics data MAPINFO?

In data exchange, will MAPGIS point, line and plane file into MAPINFO, the system will prompt "Your MAPGIS data without projection, the proposed converted into MAPINFO before a meaningful coordinate system." Then, in the prior MAPGIS data into MAPINFO; what needs what kind of projection into a coordinate system do? Only the following two conditions on the line.

(1) graphic coordinate units converted to meters.

(2) Coordinate units converted to meters of the graphics, some parameters will directly affect the conversion result.

鈶?In MAPGIS5.32 in its current parameters of the map type of map user-defined types can not be rectangular coordinates for the earth; the current map projection parameters parameters, there must be an ellipsoid parameters. Otherwise, through the "Edit current map parameters" for editing and save edits.
鈶?In MAPGIS6.0, in the current map coordinate system parameter setting its type, coordinate type must be "right-angle projection plane," ellipsoid parameters to be effective, that is: there must be an ellipsoid parameters.

26. How to make a DXF file into MAPGIS comparison table?

First look at the four document file name, meaning and purpose. In MAPGIS6.1 installation is complete, the .. MAPGIS61SLIB directory has four files, ARC_MAP.PNT: AUTOCAD blocks (symbols) and MAPGIS subgraph table; ARC_MAP.LIN: AUTOCAD form of (linear) and MAPGIS Line type table; CAD_MAP.TAB: MAPGIS layers and layers AUTOCAD table; CAD_MAP.CLR: MAPGIS AUTOCAD color and the color table.

So then about how to edit the four tables (files). (Note: To open and edit the four tables can be opened directly, or WINDOWS in tablet notepad, because these four files are text file format).
(1) graph table ARC_MAP.PNT

Open this file we will see the following format:

234 112
243 213
243 314
... ... ... ...

Previous 1 234123422433 behalf AUTOCAD software block name (symbol), followed by a 121 314 on behalf of MAPGIS System Code (Note: not child drawing number, the code in digital mapping system in sight. Method is to start Digital Mapping system, create a new measurement project file, then you'll see some code to class management box, such as triangular points encoded as 1110, the standard point code is 1210).

(2) linear table ARC_MAP.LIN

Open this file we will see the following format:

234 112
234 213
234 314
... ... ... ...

In front of a representative of AUTOCAD 234,123,422,343 in the form of name (Note: If a line is used with the layer linear way, then this linear form can not be transferred according to the MAPGIS in control. Therefore, if such , please change the line into actual linear linear), followed by a 121 314 on behalf of MAPGIS system code (not the line model, the code in the digital mapping system, where can see).
(3) layer table CAD_MAP.TAB

Open this file we will see the following format:

0 TREE_LAYER
1 STREET
2 TIC
... ... ... ...

In front of an 012 number on behalf of MAPGIS system layer, followed by TREE_LAYER STREET TIC on behalf of AUTOCAD in the layer name.
(4) color table CAD_MAP.CLR

Open this file we will see the following format:

110
24
36
... ... ... ...

In front of an 123 number representative of the color of MAPGIS system, followed by a 1 046 number on behalf of AUTOCAD in color.

The four tables are done editing, please do not forget to save the file. Conversion steps described below:

The first step: the AUTCAD the DWG format as AUTCAD data exchange format DXF Format (DXF format on the conversion, please refer to the AUTOCAD books). In the conversion, note the following points:

鈶?In converted into DXF file format, choose the best version of R12;
