This article illustrates the extension-shrink menu code implemented by JavaScript. Share to everyone for your reference.

No link to the menu, want to use their own add, and then beautify, absolutely enough personality it. The screenshot of the running effect is as follows:

Record LockA single index record is locked, the record lock is always indexed, not the records themselves, even if there is no index on the table, then InnoDB creates a hidden clustered primary key index in the background, so the hidden clustered primary key index is locked. So when an SQL does not take any indexes, it will add an X lock behind each clustered index, similar to a table lock, but the principle and table lock should be completely different.

About innodb locks (record, gap, Next-Key lock) and innodbnext-key Record lock locks a single index record. Record lock always locks the index instead of the record itself, even if the table does not have any indexes, then innodb will create a hidden clustered primary key index in the background, and the lock is the hidden clustered primary key index. Therefore, when an SQL statement does not take any index, the X lock will be applied after each clust

Overview:===============An archive gap is a range of missing archived redo logs created whenever the standby system is unable to receive the next archived redo log generated by the primary database. For example, an archive gap occurs when the network becomes unavailable and automatic archiving from the primary database to the standby database stops. When the network is available again, automatic transmissi

From 9i, Oracle provides two types of log gap detection and processing mechanisms. For gap processing, the fal _ * parameter is not required in some cases. 1. Automatic Gap Resolution2. FAL

In Oracle Data Guard, the Redo Gap is generated because of some network or other problems, resulting in the interruption of the redo transmission. After the fault is eliminated, these redo files that have not been transferred will be discovered by some processes and transmitted to the slave database.Terms:ARC: archiving processMRP: Media Recovery Process, responsible for applying redo on the slave DatabaseRFS: Remote File Server, which receives the re

Redogap is generated when the redo transmission is interrupted.Generally, when the redo transmission service is restored, oracle automatically checks the gap and solves it by itself. The time required to fix the gap depends on the gap size and the network condition between the redo source database and the redo destination database. If there is a

Gap is created by the fact that the archive log between the repository and the main repository may be inconsistent due to network and other reasons between the Dataguard master and standby.Steps to resolve gap:1. Get gap details in the standby library2. Copy the required archive logs from the main library to the standby library3. The Standby library registers the
