Embodiment Construction

[0033] The solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] A high-performance log record query method for an integrated circuit production line handling system includes the following steps:

[0035] Each module calls the log client to send the log information to the log server;

[0036] After the log server receives the log data, it stores the log data into the memory information list in the memory;

[0037] Check the size of the currently connected database to determine whether the disk space occupied by the database exceeds the set value; if the database size exceeds the set value, create a new database named after the current time and connect to the new database; if the database size does not exceed the set value value, continue to connect to the current database;

[0038] Periodically traverse the memory information list, obtain a log in the memory list, and separate the log information i...

Abstract

The invention relates to a high-performance log record query method for an integrated circuit production line carrying system. The method includes the following steps of calling log client-sides through all modules to send log information to a log server, storing log data into a memory information list in a memory after the log server receives log data, detecting the size of a currently-connected database, regularly traversing the memory information list, separating out log information, storing the log information in the database, positioning the database according to the time range to be inquired about, inquiring about the log data in the database, and forming new log information through combination, and returning the new log information to a user interface. By means of the method, the high-performance log storage and query can be achieved, the space occupied by disks can be saved, and the data storage and query efficiency can be improved.

Description

technical field [0001] The invention belongs to record storage technology, in particular to a high-performance log record query method for an integrated circuit production line handling system. Background technique [0002] With the rapid development of integrated circuit technology, the majority of manufacturers have higher and higher requirements for the handling system of integrated circuit production lines. In the production process, especially when some abnormal situations occur, it is very necessary to have a high-performance logging system to find the cause of the problem and to improve the equipment and industrial system. [0003] In the production process of integrated circuits, a large number of log records are generated every day, and most of these records are repeated. Conventional log recording systems store all log records sent by all devices in the database unchanged, which will cause a lot of data redundancy and take up a lot of disk space. Contents of the...
