Burleson Consulting wrote the book on proactive Oracle database monitoring and table growth monitoring, a preemptive method to identify and correct anomalies before they effect your database. RPM for Oracle is a proactive Oracle monitoring solution, expert techniques that form a preemptive protection layer to ensure continuous availability of all mission-critical Oracle databases. RPM for Oracle is a complete solution, running on an independent server for complete proactive monitoring of all aspects of Oracle, including the server, disk and network. The Remote Preemptive Monitor has these components, all designed to provide early-warnings for impending problems.
The client application has Oracle Database libraries linked into it that provide the APIs required to communicate with the database. Client and Server Processes Client processes oracle writer service in important ways from the Oracle processes interacting directly with the instance. The Oracle processes servicing the client process can read from and write to the SGA, whereas the client process cannot.
A client process can run on a host other than the database host, whereas Oracle processes cannot.
On the client host, a search of the processes for either sqlplus or sample shows only the sqlplus client process: During a connection, a communication pathway is established using available interprocess communication mechanisms or network software.
Typically, a connection occurs between a client process and a server process or dispatcher, but it can also occur between a client process and Oracle Connection Manager CMAN. A database session is a logical entity in the database instance memory that represents the state of a current user login to a database.
For example, when a user is authenticated by the database with a password, a session is established for this user. A session lasts from the time the user is authenticated by the database until the time the user disconnects or exits the database application.
A single connection can have 0, 1, or more sessions established on it. The sessions are independent: If Oracle Net connection pooling is configured, then it is possible for a connection to drop but leave the sessions intact.
Multiple sessions can exist concurrently for a single database user. As shown in the following figure, user hr can have multiple connections to a database.
In dedicated server connections, the database creates a server process on behalf of each connection. Only the client process that causes the dedicated server to be created uses it. In a shared server connection, many client processes access a single shared server process.
Figure One Session for Each Connection Figure illustrates a case in which user hr has a single connection to a database, but this connection has two sessions. Opening a new terminal and connecting to the instance as a different user, the following query shows that the connection with the address 3BE2E41C is still active.
A composite database operation is activity between two points in time in a single database session. You can divide a large set of tasks into database operations, and subdivide operations into phases, so that you can more easily monitor, compare, and tune tasks. You cannot nest operations and phases within one another.
By configuring the job as a database operation, you can easily identify and tune the expensive steps in the job. Each execution of a database operation is uniquely identified by a pair of attributes: Two occurrences of the same database operation can execute at the same time using the same name but different IDs.
Each execution of a database operation with the same name can contain different statements.Answer: Volume Shadow Copy Service (VSS) is a Windows shadow copy utility used in conjunction with the Veeam Backup VSS integration.
The Oracle VSS writer supports log, copy, full, differential, and incremental backups, just like RMAN. I am unable to find any literature to evaluate which solution to use when backing up my Oracle 11g DB. The attempt is to perform online backups by enabling ARCHIVELOG mode. Oracle VSS Writer vs.
RMAN. Ask Question Edit: I have gone through individual documentation for RMAN and VSS Writer. I am looking for comparative analysis. oracle.
What is SOA [Service-Oriented Architecture]?. SOA is an IT architecture strategy for business solution (and infrastructure solution) delivery based on the concept of service-orientation.

Apr 24, · Volume Shadow Service(VSS) is a must if you are willing to use any VSS enabled tool to do the backup. You have told us very less to comment. If your administrator is saying that the issues are because of this service, as a trial, you may stop it and see if its working out for you.
