About the installation verification program


Note: The Installation Verification Program (IVP) has been added to the automated Systems Maintenance process as of May 1, 2013,

but you can still access the IVP interactively using this screen




The installation verification program (IVP) will inspect your database for anomalies, repair those it can, and report on those it cannot.


For this purpose, when the IVP is launched, the first step is to obtain access to a table with metadata (data about data) about the files currently in the Build Libraries (development libraries from which products are created). It compares your installation with the information about the current production installation and lets you peruse the results.


As new releases are created, information about the development libraries that contributed to the release is extracted and stored in a file named BLDLIST.DBF a copy of which is stored on our web server for IVP access.


To launch the IVP, click the IVP command (or enter =IVP) on the command line





Click CHECK THIS INSTALLATION'S FILES to launch the IVP to check this computer.  


When processing completes, a screen like this screenshot will appear. The operator can use the commands on this screen to interactively inspect the results of the process (see the SHOW

options below)..








Below are some sample screens showing some of the SHOW options on the IVP screen. These screens are more populated because they depict files on a test computer that's been setup to

contain exceptions. You will probably see fewer items on your exceptions reports.  



By selecting one of the SHOW options on this screen, you can control the display to show only The files listed on this screen screen will look like this:




OK Files


These files are exact matches to their counterparts in the H2OS product Build Library.



Mismatched fields




These files are potentially troublesome and should be investigated.


Please send this report to H2OS Customer Service for follow-up




Mismatched size/recs





These files are smaller or larger then their counterparts in the current H2OS Build Library, typically the result of normal database operation.







Not installed





This list of files that exist in the current H2OS Build Library but not in this installed should be examined to determine if one or more of these files should be installed.  


For follow-up, please send your IVP report to H2OS Customer Service.





Extra files



This is a list of extra files in this installation, discovered by comparing this installation's files with those in the current H2OS product Build Library.


Extra files are those that have been created by H2OS or otherwise added to the H2OS installation's folders (c:\h2os and sub-folders) since product installation.







Ignored files



This is the list of files that you have chosen to ignore from the exception screen by selecting the IGNORE option on the IGNORE pulldown menu which appears in the leftmost column of each report.


You can turn off the IGNORE flag by using the pulldown menu in the IGNORE column. Select the ? from this menu to turn off the IGNORE flag for one or more files.




Description of this report screen














Pulldown menu allows selection of an IGNORE option, which tells the system that this file is okay and suppresses this file from subsequent reports. Check the IGNORED FILES SHOW option to view ignored files.
