When developing the discuz logon script, a problem occurs: How to verify the real logon success of a virtual user? Of course, people familiar with the LoadRunner tool will know that checkpoints are used in the script, yes, that's right! We know that there are two LR checkpoint functions: Text checkpoint web_find (), web_reg_find (), and image checkpoint web_image

Access control This is a measure to restrict unauthorized access to the company's network and information resources. An important factor in evaluating access control is whether it can be applied to all exist

The CKPT type of the Oracle checkpoint is used to write the checkpoint to the control file and data file header. Check points are of the following types: Thread checkpoints is the database check point, which may occur in the following cases: closing the database consistently; alter systerm checkpoint statement; switching online redo log file; alter database begin

The buffer cache memory of the CKPT checkpoint queue contains the chain and bufferLRU to concatenate available blocks (based on the Access Frequency). LRUW concatenates dirty blocks (Access Frequency) and cold-end blocks are first written to the hard disk. When CBC reads data blocks into the memory, it uses CKPT (chain): 1. It links dirty blocks. 2. It links the first dirty time (from small to large) the address of the RBA redo block address log block

The SCN and checkpoint mechanism of OracleThe SCN appears in several forms on Oracle's documentation, one for system change number and one for system Commit, and in most cases, the definition of Systems change numbers is more accurate.The SCN (System change number) is what is commonly referred to as an alteration, a very important data structure in the database that identifies the version that the database commits at some exact moment. When a transact

1, the Oracle log principle Redo Stream (redo log stream) RBA (the redo byte address consists of 4 parts: The log thread number, the log sequence number, the log file block number, and the log file byte offset, which is 10 bytes in length.

Many people add a Chinese checkpoint to the LoadRunner test script. The check fails. Why? In fact, the conversion between the tested system and the LoadRunner Character Set fails. Let's explain it one by one. We know that LoadRunner has a character set setting in the recording option: Recording Options> advanced> support charset. Here we can set the character set supported by LoadRunner. So what is the relationship between the character set of the tes

LRCheckpoint The purpose of setting checkpoints is not only to verify that our scripts are correct, but also to make the test results more convincing, therefore, we recommend that you add checkpoint settings in all test scripts.

One of the most important commands in SQL Server is checkpoint, which is primarily to write data from the cache into an MDF file.In fact, when we do insert, UPDATE, delete, the data is not directly written to the database corresponding to the MDF file, but written in the cache, which is a bit like an electric donkey, because too frequent write will make the life of the disk greatly reduced.Can be seen from the visual. Data is written to the MDF data f
