lock (Exclusive Locks, X Lock) and shared lock (Share Locks, S lock). When a data object is added to an exclusive lock, other transactions cannot read and modify it. Data objects with shared locks can be read by other transactions, but cannot be modified. The database uses these two basic types of locks to control the concurrency of a database's transactions.Category of content protected by lockOracle provides a multi-granularity blocking mechanism that can be divided into protected objects and

There is a potential danger that the chosen result set is not locked and there is a possibility that another user might be able to change it. So Oracle still suggests a pessimistic blockade, because it's safer.Four, DML lockThe most important lock in Oracle is a DML lock (also known as data locks, lock). T

This locking mode is higher than the level of row-level exclusive and shared locks, and you cannot perform DML operations on the same table or add shared locks. RS Lock is the leas

Juniper EX systems and VPLS on the MX ser IES and the QFabric System, with integrated L2 and L3, which scales massively.VXLAN does not has a control plane and it uses multi-cast to flood the network for endpoint discovery, so it poses contro L Plane scalability and network manageability issues. This could is addressed by integrating VXLAN with a SDN controller or by deploying another overlay tunneling protocol tha T is managed from an SDN controller instead. There is a number of such devices on

loopback interface. The specific method is to take 0 of the starch decimal ring back to the IP address of 12 characters address, then bar 12 characters 4 digits for a group, divided into 3 groups, separated by dots, in the form of 16. A node can have up to 3 NSAP addresses, but the sysid of each address must be the same, except for the regional address. When a router running is-is has more than one net address, it is called a multihomed (multihoming). It is important to note that multiple hosts

Foreman can use the Facter component to display system directory information and provide real-time information from Puppet host reports. Foreman is able to prepare you to manage all the work of new machines. Its design goal is to automate all manual management work, and Foreman can reconfigure the machines.

When I first learned about Juniper, I really didn't understand anything. I didn't mean that I didn't understand TCP/IP, but simply couldn't configure the Juniper Router. The reasons for this are mainly from two aspects: the simulator was too long to start, and there was too little information on the Internet. When I configured the Juniper Router on Gns3, the direct connection was disconnected, hitting people ...... Haha, when you can configure IP addresses and simple commands, you will find that

[Juniper] common configuration methods for daily maintenance of switches and routine maintenance of juniper The juniper device is different from other vendors, and adopts the configuration concept of submitting for effectiveness. This greatly reduces misoperations. Note: All configurations do not take effect immediately after they are configured. You need to submit a commit statement to take effect. 1 Boot Guide After boot: Login: root Last login: Fri Jan 17 22:21:55 on ttyd0 ---

Today we recommend a good open source routing operating system---Vyos, is also my personal favorite of a soft router. Vyos is based on the Debian Gnu/linux, which provides similar operations to other Junos-like iOS, Juniper, and is particularly comfortable to configure, especially with commands such as compare, rollback, etc. Easy to compare configuration and error rollback, won my heart.As a result of the use of Mikrotik RouterOS, in the process of u

These devices are all being certified at the University of Texas's San Antonio OCP certification solution lab. Although there is a lot of controversy about these devices and programs, the devices sold by these vendors have been certified as OCP-compatible devices.
