Environment and version:

OS:win10-64 bit

DatabaseServer:oracle12c edition 2

The author did not solve this problem completely, but chose to ignore it. But all the relevant methods have been tried.

PRVF-3919: unable to retrieve the value of the environment variable "PATH"

Reason: the path environment variable is too long. The value of the environment variable path exceeds 1023 characters and cannot be set.

Solution: modify the path environment variable.

Edit the Path and select all to copy all the paths into the text document.

Create a new system variable named path2

Cut all variables in Path and copy them into path2 and save them

Delete all selections in Path to default values

% SystemRoot%\ system32;%SystemRoot%;%SystemRoot%\ System32\ Wbem

Finally, add the% path2% reference path2 after the default value and save it.

Notice each semicolon.

Other possibilities for triggering PRVF-3919: 1: physical memory-this prerequisite tests whether the total physical memory of the system is at least 922MB (944128.0KB)

Expected value: NumberA

Actual value: NCMA

Error list:

PRVF-7531: unable to perform physical memory check on node "XP-201307311325"

Cause: unable to perform a physical memory check on the indicated node. Action: make sure you can access the specified node and view memory information. 2: physical memory-this prerequisite tests whether the total physical memory of the system is at least 922MB (944128.0KB)

Expected value: NumberA

Actual value: NCMA

Error list:

PRVF-7531: unable to perform physical memory check on node "XP-201307311325"

Cause: unable to perform a physical memory check on the indicated node. Action: make sure you can access the specified node and view memory information. 3: swap space size-this prerequisite tests whether the system has sufficient total swap space

Expected value: NumberA

Actual value: NCMA

Error list:

PRVF-7574: unable to perform swap space size check on node "XP-201307311325"

Cause: unable to perform swap space check on the indicated node. Action: make sure you can access the specified node and view the swap space information.

PRVF-7531: unable to perform physical memory check on node "XP-201307311325"

Cause: unable to perform a physical memory check on the indicated node. Action: make sure you can access the specified node and view memory information. 4: free space: XP-201307311325:C:\ DOCUME~1\ ADMINI~1\ LOCALS~1\ Temp this prerequisite tests whether the file system has enough free space.

Expected value: NumberA

Actual value: N/A5: architecture-this prerequisite tests whether the system has a certified architecture

Expected value: NumberA

Actual value: NCMA

Error list:

PRVF-7536: unable to perform architecture check on node "XP-201307311325"

Cause: the system architecture cannot be determined. Action: make sure you are using the correct package. 6:Environment variable: "PATH"-This test checks whether the length of the environment variable "PATH" does not exceed the recommended length.

Expected value: NumberA

Actual value: NCMA

In fact, if you look at the contents of these six errors, there are only two problems: first, the database cannot access the node, so you cannot check the memory, temporary space and other problems (such as the first five errors); second, the environment variable has no parameters, resulting in substandard length. Solutions to these two problems

1: enabling service service is usually started by default, because database installation depends on the support of this service.

2: set up a network shared C disk, and only at the command prompt can the net share centering memory and other information be placed on disk C (delete using net share C $/ del) to check the availability of the environment.

3: operation: my computer-> Advanced-> Environment variable-> system variable-> path; back up the original path value (be sure to back up)

Replace it with:% SystemRoot%\ system32;%SystemRoot%;%SystemRoot%\ System32\ Wbem; and see if there is path in the "user variable", and if so, delete it.

Then log out, log in again, and install again.

4: click the database software to execute as an administrator. By default, the system does not open this file as an administrator, so you cannot access disk C.

5: then log out, log in again, and install again.
