All the logs are stored permanently for long-term usage in a proprietary database. In this blog post, we’ll discuss how to monitor the event logs using Lepide Event Log Manager. Setting up the Database The software at the very first time will show the following screen asking you to setup the database for storing the event logs. Figure: Welcome Screen You’re required to enter the values like SQL Server Name, Database Name, Authentication mode, and the login credentials. After providing the necessary inputs, click on the button “Test Database Connection” to test the database connectivity.
Prepare a boot disk that includes and loads the necessary network drivers and maps the disk images directory from the network. 2. Copy over the DOS Ghost Server program (dosghsrv.exe) to the same disk and add it to the autoexec.bat file. 3. Copy over the wattcp.cfg file to the disk and change the IP Address, Subnet Mask and Gateway according to network.
A differential backup is faster due to its ability to make a copy of the database since the last complete backup. Differential backups are simpler to use for recovery, therefore are used more frequently than complete backups. SQL Server has the ability to backup to a disk and a tape. SQL Server provides a wizard for setting up database maintenance plans such as scheduling database and log backups. Both log and data files are created by SQL Server.
NoSQL are designed to expand transparently to take advantages of new nodes and they are built using low cost hardware, so cost shouldn’t be a problem. Big Data In today’s world, the transactions are so frequent that the data generated out of these transactions is huge. It is very difficult to store these huge transactional data in the traditional database systems. NoSQL with its elastic scaling feature, it is possible to increase the size of the database to store huge amount of transactional data. All the challenges involved in processing these huge transactional data can be overcome with NoSQL database systems.
Oracle time travel concept: Oracle Flashback Oracle developed a suite named Flashback Technology which enables Oracle application users and database administrators to wind the clock back and examine their database objects and data in a previous state without having to restore using backup media. Flashback query allows a user to view the data quickly and easily the way it was at a particular time in the past, even when it is modified and committed, be it a single row or the whole table. What situations call for the use of the flashback feature? According to the Oracle documentation, Flashback technologies are applicable in repairing the following user errors. • Intended or unintended DROP TABLE statements • Intended or unintended update, delete or insert transactions • Intended or unintended batch job or wide-spread application errors There are more features of flashback that one can imagine.
They including the data dictionary management, data store management, security management and also backup and recovery management. A data dictionary is a place where the DBMS stores definitions of the data elements and their metadata. All programs that access the data in the database will work through the DBMS. It uses the data dictionary to look up the required data component structures and relationships, thus the users do not have to code such complex relationships in each program. In addition, any changes made in database structure will be automatically recorded in the data dictionary, thereby freeing the users from having to modify all the programs that access the changed structure.
Let's say you have a bunch of stuff you just deleted, and need to make sure nothing that was on the system can be undeleted and accessed again. This utility creates a file the size of the free remaining space on your drive and fills it with space, then deletes it.
Programs installed on the local host will have some processes that run in the background. Some of these services start with the operating system and do not need to run until the program is started. Memory RAM3 (random access memory) may be added to a computer. Checking the manufacture’s requirements for RAM type and maximum RAM-per-slot will assist in ordering or upgrading.

Data provisioning stores the organizational structure regulations in tables in its database, so these regulations can be changed without any difficulties when management decides to modify the organization. OCF created two relational databases to support data provisioning —one to support transaction processing and another to support information delivery. They used for transaction processing technology IBM’s DB2 running on the mainframe, designed to process high transaction volumes fast. For the information delivery technology they used a TERADATA database machine - a combination of hardware and software that is optimized for answering information questions. 2.
A VPN can grow to accommodate more users and different locations much easier than a leased line. In fact, scalability is a major advantage that VPN's have over typical leased lines (dedicated circuits). Unlike with leased lines, where the cost increases in proportion to the distances involved, the geographic locations of each office matter little in the creation of a VPN. Descriptions / Types Virtual Private Networks allow enterprises to utilize cost effective, secure, and scalable hardware to extend their wide area network. These networks are cost effective in that they are able to connect remote users to the corporate network without the need for expensive dedicate WAN links or modem banks.
