Recently, when using Cold Standby tar for Oracle database migration, You need to filter out the files exported by datapump under the current database file, otherwise, a large tar file will be generated and the network transmission time will be consumed. In fact, the tar command provides a filtering function, but many people do not know it because the filtering function is usually used less. This article describes how to filter unwanted files or folders under the tar command.
1. Demo Environment
# The BBB, CCC, and BNR subdirectories exist in the current tree directory. Now, you need to filter out the dump file of gz, that is, you do not need to package [oracle @ linux1 ~]. $ Tree AAAAAA | -- BBB | '-- SYTST_temp.dbf | -- BNR | -- dump | -- emp.dmp.gz | -- tb.dmp.gz |' -- xx.dmp.gz | '-- full | -- CCC | '-- tempSYTST. dbf | -- SYTST. sh' -- initSYTST. ora5 directories, 7 files
# Method 1: Filter Using the exclude parameter and use the wildcard [oracle @ linux1 ~] $ Tar-czvf A1.tar.gz -
) connections are the opposite, each connection is identified by the Server Load balancer IP (MIP: mapped IP) and a random port. That is:
MIP: randomport-> realserverip: 80
In this case, the Server Load balancer acts as a client and its port is limited by the maximum number of TCP/IP Ports 64 K (65536). Therefore, you can only create a server connection (server connnections) of up to 64 K ).
The bottleneck is likely to occur on the server connection of the Server Load balancer. In this case, how
to connect and monitor multiple XenApp or XenDesktop sites.Director Displays session and site information from the following sources:By using Microsoft Remote Assistance, you can also view and interact with user sessions.
Real-time session data from the broker service in the Controller, including data obtained by the broker service from the broker Agent in the VDA.
Historical site data from the Monitor Service in the Controller.
HDX insight captures data from
decimal: 1So you can also set this:Setuid:chmod 4755 xxxSetgid:chmod 2755 XXXStick bit:chmod 1755 xxxFinally, after some files have special permissions set, the letters are not lowercase s or T, but uppercase s and T, and the special permissions for this file do not take effect because you have not given it a corresponding user's X permission.
The size of hard links and soft connections.
Through the test below, the hard link is the same inode node as the source file, pointing to the same file,
as ip:80).
And then from the server Side (Load balancer->realserver) to analyze:
The number of connections on this end is just the opposite, and each connection is identified by the IP of the load balancer (called mip:mapped IP) and the random port. namely: Mip:randomport-> realserverip:80
In this way, because the port of the load balancer is also limited by the maximum number of ports of TCP/IP, 64k (65536), a maximum of 64k server connections (server Connnections) can be established.

Preparations
1. create a test database
Create database testQuery
2. create a test table
CREATE TABLE table1( uid VARCHAR(10) NOT NULL, name VARCHAR(10) NOT NULL, PRIMARY KEY(uid))ENGINE=INNODB DEFAULT CHARSET=UTF8;CREATE TABLE table2( oid INT NOT NULL auto_increment, uid VARCHAR(10), PRIMARY KEY(oid))ENGINE=INNODB DEFAULT CHARSET=UTF8;
3. Insert data
Insert into table1 (uid, name) VALUES ('AAA', 'Mike '), ('BBB', 'Jack'
execution is like this1 from Although I did not think so, but a look is still very natural and harmonious, from where to obtain, constant filtration conditions, to choose the same or different, the order, that only know how to take the first few.
