The reason for this article is that there is no root permission on the company's servers, but you need to use Python to access Oracle, regardless of whether you use PIP to install components or to install Oracle's client. This article resolves the issue.

What if application a requires Jinja 2.7 and application B needs Jinja 2.6? You can create different virtual environments for different applications at this time.In this case, each app may need to have a "standalone" Python runtime environment. Virtualenv is a python run environment that is used to create a "quarantine" for an application.1 PIP3 Install Virtualenv2 virtualenv-p c:\python35\python3.exe--no-site-packages ENV35 (remember that the virtual

In this case, however, there is still another thread that is technically "sneaking in" and the possibility of modifying the same file as we begin to read and modify the file. But using the above technique, if this happens, it throws an exception to let us know. This is the optimistic lock, which is technically not locked in the process of reading because we are optimistic that there will be no change until we make the subsequent changes. When we do this
, version data prevents the loss of two updates, and the first-level session cache ensures that the state of the persistent load data is isolated from other transaction modifications to the data, so it is possible to use authorization to read quarantine and version data for all database transactions.Repeatable read provides better efficiency for database queries (only for those long database transactions), but because Phantom reads still exist, there

Isolation tests can ensure the effectiveness of individual components. At the same time, it is also a way to check the quality of the design between components. If you want to execute a component separately and rely on many other components, it's a bit difficult to isolate, so you

solution of anti-virus software compromise is to back up a suspicious program file to a folder called "quarantine", and then destroy the original file. This may achieve the purpose of killing unknown viruses, but we cannot ignore the possible serious consequences, such as virus infection of a key file or important document, if anti-virus software can't help but eliminate it, it is likely to cause system crashes or even economic losses, because a soun

During the installation process, Qurb adds three buttons "Qurb", "allow", and "Block" to the user's mail client program, and an isolated folder icon. Qurb then creates a whitelist Based on the Outlook contact database and calendar, and all sent, received, opened, or stored emails. Even if you rarely update contacts, the whitelist created by Qurb is comprehensive and accurate.
Of course, you must always check the isolation folder. This process is simple and i

5. The virus is constantly detected. Will our virus code keep increasing?
In the current situation, as new viruses are detected, new virus features will be added to the virus pattern, and our virus pattern will continue to increase.
6. Will the Scan Engine continue with the virus if it is not updated?
A virus code contains specific characteristics of a virus. The Scan Engine compares these features to determine whether the scanned file is a v
value, and the last 16 bytes must be the MD5 Hash Value of the binary value minus the value of the 27 bytes.Trojan Maintenance
The first function of a Trojan is to set a Launch Agent to maintain the trojan. The Launch Agent runs every time a user logs on. Trojan will copy itself ~ /Library/Logs/. Logs/corevideosd (if the Trojan horse has root permission, it will be copied to/Library/Logs/. Logs/corevideosd), and in ~ Create a Launch Agent plist in/Library/LaunchAgents/com. google. plugins. plis
