This is the first of two demonstrations about In-Memory caching new features, introduced in Oracle Database 12.1.0.2. This one illustrates the Full Database In-memory Caching feature enabling an entire database to be cached in memory when the database size is smaller than the buffer cache size. Caching and running a database from memory leads to huge performance benefits. Copyright © 2014 Oracle and/or its affiliates. Oracle® is a registered trademark of Oracle and/or its affiliates.

https://www.lead4pass.com/1Z0-060.html High quality Oracle Database 1Z0-060 dumps pdf training resources and study guides download free try from lead4pass, pass Oracle 1Z0-060 exam easily. Exams: QUESTION 1 Which three are true about the large pool for an Oracle database instance that supports shared server connections? A. Allocates memory for RMAN backup and restore operations B. Allocates memory for shared and private SQL areas C. Contains a cursor area for storing runtime information about cursors D. Contains stack space E. Contains a hash area performing hash joins of tables Correct Answer: ABC Explanation: The large pool can provide large memory allocations for the following: / (B)UGA (User Global Area) for the shared server and the Oracle XA interface (used where transactions interact with multiple databases) /Message buffers used in the parallel execution of statements / (A) Buffers for Recovery Manager (RMAN) I/O slaves Note: * large pool Optional area in the SGA that provides large memory allocations for backup and restore operations, I/O server processes, and session memory for the shared server and Oracle XA. * Oracle XA An external interface that allows global transactions to be coordinated by a transaction manager other than Oracle Database. * UGA User global area. Session memory that stores session variables, such as logon information, and can also contain the OLAP pool. * Configuring the Large Pool Unlike the shared pool, the large pool does not have an LRU list (not D). Oracle Database does not attempt to age objects out of the large pool. Consider configuring a large pool if the database instance uses any of the following Oracle Database features: * Shared server In a shared server architecture, the session memory for each client process is included in the shared pool. * Parallel query Parallel query uses shared pool memory to cache parallel execution message buffers. * Recovery Manager Recovery Manager (RMAN) uses the shared pool to cache I/O buffers during backup and restore operations. For I/O server processes, backup, and restore operations, Oracle Database allocates buffers that are a few hundred kilobytes in size. QUESTION 2 What are three purposes of the RMAN "FROM" clause? A. to support PUSH-based active database duplication B. to support synchronization of a standby database with the primary database in a Data environment C. To support PULL-based active database duplication D. To support file restores over the network in a Data Guard environment E. To support file recovery over the network in a Data Guard environment Correct Answer: BDE Explanation: DE: * With a control file autobackup, RMAN can recover the database even if the current control file, recovery catalog, and server parameter file are inaccessible. * RMAN uses a recovery catalog to track filenames for all database files in a Data Guard environment. A recovery catalog is a database schema used by RMAN to store metadata about one or more Oracle databases. The catalog also records where the online redo logs, standby redo logs, tempfiles, archived redo logs, backup sets, and image copies are created.

Adjust Virtual Memory on windows 10 to optimize system performance
 
03:00
Adjust Virtual Memory on windows 10 to optimize system performance. Virtual memory combines your computer’s RAM with temporary space on your hard disk. When RAM runs low, virtual memory moves data from RAM to a space called a paging file. Moving data to and from the paging file frees up RAM so your computer can complete its work. Read More About Virtual memory : http://www.windows101tricks.com/2016/04/adjust-virtual-memory-in-windows-10-to-optimize-performance.html Every time you open more applications than the RAM on your PC can accommodate, the programs already present in the RAM are automatically transferred to the Pagefile. This process is technically called Paging. Because the Pagefile works as a secondary RAM, many times it is also referred to as Virtual Memory.

This issue is very common and commonly faced by DBA, developers and server management team on production server i.e. SQL server leads into 100% CPU usage and also start consuming all available memory. Now most of the time you have seen technical people restarting sql services, or killing long running processes and even restarting complete server, and they can avoid this situation. Before starting any thing I would like to discuss a common myth people have that this is happening because of long running queries only. Which is not all ways true, some times: Longer running query can be problem Query having maximum worker time are also problem Query execution count can also cause problem For script check below link: http://www.techsapphire.in/index/sql_server_100_cpu_usage_fix/0-166

Oracle Enterprise Manager 12c: Deploying JVMD and ADP Managers
 
08:54
Oracle Enterprise Manager Cloud Control 12c provides extremely deep end-to-end performance monitoring and diagnostics. While the majority of the monitoring can be handled via out of container agents, some require very light weight in-container agents. JVM diagnostics is a very light weight diagnostics in-container solution that doesn't even contain byte code instrumentation (no restarts, instant monitoring with just a war file agent) and has near-zero overhead. Application Dependency and Performance (ADP) provides component level dependency analysis which is key for diagnosing applications using MVC frameworks like ADF, JSF, Swing, or portal and SOA frameworks. This particular demo illustrates how the additional managers for these advanced options can now be quickly deployed via wizards in the 12c release of Oracle Enterprise Manager.

#5 SAP ASE 16 Learning-Configuring Memory Parameters
 
20:13
SAP ASE 16 Learning Part 5 Configuring Memory Parameters. To Learn or Teach Linux visit www.theskillpedia.com, A Marketplace for Learners and Trainers. Session 5 Configuring Memory Ram N Sangwan Memory and Cache configuration Memory allocated to Sybase ASE The maximum memory parameter max memory should be set as high as possible taking into consideration anything else which is running on the same host. You have to be aware of any other Adaptive Servers, Sybase products or other database systems that may be running on the box and taking memory. Note that having multiple engines configured for a server will not increase the memory overhead as the configured memory is shared among the engines. Memory Configuration Case study: one host and one ASE, plus the backup server and replication server. If we have a running a Sybase then leaving 600-800MB to the operating system plus the replication server and the backup server should be sufficient. The max memory that the backup server will take is 144MB. It will be safe to give the replication server around 200MB. That leaves the rest to OS. Memory Configuration Memory Configuration Total physical memory run value is the one telling you how much memory ASE is currently using. For example in this case ASE has 4GB of max memory but only using 1957416/512 = 3823MB in practice. Memory Configuration additional network memory This is the memory required for networks. allocate max shared memory During start up ASE allocates memory based on the value of total logical memory. However, if the configuration parameter, allocate max shared memory has been set, then the memory allocated will be based on the value of max memory. Unless you are competing with other resources, leave this parameter as default. Memory Configuration Cache Configuration Large IO and Multiple Buffer Pools When more than one buffer pool is available in a cache, the ASE optimizer determines the optimal page size for each query and uses the appropriate buffer pool. ASE allows you to configure up to four larger page sizes. With 8K page size, buffer pools of 8K, 16K, 32K and 64K can be configured.
