=ethernetOnboot=yes Two, a single network adapter to bind multiple IPsSometimes we need to configure multiple IPs on a NIC, for example, in the example above, we also need to configure IP 192.168.168.2 and 192.168.168.3 for eth0. Then you need to create a new two configuration file under/etc/sysconfig/network-scripts:ifcfg-eth0:0 content is as follows: device=eth0:0Bootproto=staticipaddr=192.168.168.2netmask=255.255.255.0Onboot=yes

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

It is estimated that the Checkpoint Lag calculation method of the rep process on the Oracle GoldenGate (OGG) destination end is called oraclelag. This article is original. For more information, see the source. It is estimated that the Checkpoint Lag calculation method of the rep process on the target end of Oracle GoldenGate (OGG) OGG Background: The following shows the rep process at the OGG target end.
