DB Replay settings Scale_up_multiplier not effective Set Scale_up_multiplier: BEGINDbms_workload_replay. Prepare_replay (Scale_up_multiplier => 10);End; But after setting, in Dba_workload_replays. The Scale_up_multiplier check found that this value is always 1. This is because Scale_up_multiplier does not support synchronization based on an object ID. When the value of the synchronization is object_id,scale_up_multiplier in the code, it is hard 1

The radio has been in use for a long time, and for a long time it was born a group called the Ham Tribe (^_^ cq), the man who ate ham all day. Radio and the Internet: There are also some security risks, such as: in the transmission of wireless signal does not take into account the CRC check, encryption and other security issues.Small scenario: If you use the Wireless key card to unlock the car on one day and press the second time to unlock it, then your car has been targeted by hackers!A new att

Whether you encounter this problem when using git:you're using Git for versioning, and one day you went on to work yesterday and you submitted n commits, and the result is that when you merge the remote branch, you don't notice the state of the branch you're submitting before you work .As a result, the results of your submission to the hotfix branch are all submitted to the Dev branch, and the remote branch your colleague has already submitted a lot of changes, what if you encounter this situati

Label:The role of replay tracking You can use a trace as a test tool, and when you call some stored procedures in the correct order, you will be able to regenerate specific failures. Tracking templates There are four options for saving a trace (file-to-Save As) 1. The trace files option is used to save the data in a binary format file, which is the fastest, and the least disk-byte-consuming method. 2. The trace table option is used to save the data t

Replay attacks, similar to repeated submissions of WEB forms, interface visitors use the same message body to constantly access the interface provider's process, resulting in increased pressure on the interface provider or even server failure, data loss and so on. The general practice of preventing replay attacks is for the requester and provider to contract a unique TID, which therequester carries with thi

Bkjia.com exclusive Article]Oracle 11gR1 provides the ability to capture application loads in the production environment and replay loads in the testing environment, this technology is used to determine the impact on the performance of the system, database, or application after modification. In this article, I will describe how to capture and prepare the load from the current production database in the p + 0 environment, and how to

A BackgroundLast year, a MySQL trace replay test, due to the performance schema itself to collect sample length and other limitations, the actual playback of the success rate is relatively low.Recently found an open source tool, based on tcpcopy implementation of online traffic simulation test, this open source tool is NetEase's Wang bin development, many of the company's simulation on-line test is based on tcpcopy implementation.Https://github.com/se

If the client is making a request to the server-side interface, if the request information is encrypted, it is intercepted by a third party to the request packet, although the third party cannot decrypt the obtained data, but can use the request package for repeated request operation. If the service side does not carry out anti-replay attacks, the parameter server pressure increases, the consequences of data disturbance. You can solve this problem by

Time Stamp effect The client makes a request to the server-side interface and, if the request information is encrypted, is intercepted by a third party to the request packet, which can be used to repeat the request operation. If the service side does not perform anti-replay attacks, the server pressure increases, and the use of timestamps to solve the problem. The previous article described the JWT Security verification operation, which now
