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
A letter to HR newcomers
Hello, HR!
Congratulations, you have entered a field with broad future prospects. As human resources are gradually recognized and human resources are viewed from a strategic perspective, this will be a perfect place for you to do your best.
It also reminds you that you may have entered a place with low salary, high morale, complex interpersonal relationships, and subtle relationshi
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

Label:First, Introduction Consider this scenario : If the redo log can grow infinitely and the buffer pool is large enough, it is not necessary to flush the new version of the pages in the buffer pool back to disk. Because when a outage occurs, it is entirely possible to redo the log to recover the data from the entire database system to the time of the outage. However, this requires two prerequisites: 1, the buffer pool can cache all the data in the database; 2. Redo log can grow infinitely The

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
At the end of the previous chapter, we left the question that in the model described in the previous chapter, the recovery manager had to perform a log recovery through the entire Undolog scan, which is obviously not necessary because the system outage must have been affected in the last few transactions. The previous transaction should have completed commit or rollback, no abort, then how do we know which transactions are affected, and if we know which ones are affected, then we can scan withou
