Each leaf block in the index structure stores both the key and nonkey columns. And, because there is no separate table storage area, changes to the table data such as adding new rows, updating rows, or deleting rows result only in updating the index structure. They are not stored both in the index and underlying table, as is true with heap-organized tables. They support features such as constraints, triggers, LOB and object columns, partitioning, parallel operations, online reorganization, and replication.
And, they offer these additional features:. Any portion of the row that exceeds the specified threshold is stored in the overflow segment. In other words, the row is broken at a column boundary into two pieces, a head piece and tail piece. The head piece fits in the specified threshold and is stored along with the key in the index leaf block. The tail piece is stored in the overflow area as one or more row pieces.
Thus, the index entry contains the key value, the nonkey column values that fit the specified threshold, and a pointer to the rest of the row. The AWR collects and maintains performance statistics for problem-detection and self-tuning purposes. By default, every 60 minutes the database collects statistical information from the SGA and stores it the AWR, in the form of snapshots. Several database components, such as the ADDM and other management advisors, use the AWR data to detect problems and for tuning the database.
The only requirements regarding the selection of the AWR snapshots are these:. The AWR holds only cumulative database statistics, and once you shut down the database, all the cumulative data will lose its meaning. But it does not get mounted on a database.
A single ASM instance can service one or more single-instance databases on a stand- alone server. This is true for both RAC environments and non-RAC clustered environments where multiple single-instance databases across multiple nodes share a clustered pool of storage that is managed by ASM. If a node is part of a Real Application Clusters RAC system, the peer-to-peer communications service is already installed. This is a foreground or client process which connects to the ASM instance.
The database instance knows the name of the disk group, and can therefore use it to lookup connect information for the correct ASM instance. Good for OLAP. Highly critical systems. This balancing is automatic. Available only in ASM instance.
Available in both database as well as ASM instance. Log in as the root user. Make sure you add the Oracle home directory to your path, as shown here:. Creating it now. Successfully accumulated necessary OCR keys. Creating OCR keys for user 'root', privgrp 'root'.. Operation successful.
Checking the status of new Oracle init process Expecting the CRS daemons to be up within seconds. CSS is active on these nodes. The default is 1 and the range is from 1 to 11 1 is slowest and 11 is fastest. The format of the disk string may vary according to your operating system.
You can specify a list of values as follows; this example limits the ASM discovery to disks whose names end in s1 and s2 only:. To invoke the command-line administrative tool, called asmcmd, enter this command after the ASM instance is started :. By typing followed by a command, you can get details about that command. You still have your original data file copies on disk, which you can use to restore your database if necessary. Archive the current online redo logs, and delete the old non-ASM redo logs.
This is the database that is accessed by most of your applications. Using a backup copy of the primary database, you can create up to nine standby databases and incorporate them in a Data Guard configuration. A standby database can be either a physical standby database or a logical standby database. The database schema, including indexes, are the same. This allows users to access a logical standby database for queries and reporting purposes at any time.
Thus, a logical standby database can be used concurrently for data protection, reporting, and database upgrades. Control the automated transfer of redo data from the production database to one or more archival destinations. A switchover ensures no data loss. This is typically done for planned maintenance of the primary system. The transition occurs without having to re-create either database.
Failover is performed only in the event of a catastrophic failure of the primary database, and the failover results in a transition of a standby database to the primary role. Some applications require maximum database performance and can tolerate some small amount of data loss. Primary-Side Add the parameters in init. Connected to an idle instance.

Last week I build a two nodes cluster which will be called node 5 and 6 in the clusterware. When you normally configure ASM on a cluster through GUI, it builds number of ASM instances depending on number of nodes selected in the clusterware starting from 1 and 2.
Unlike disk group it does not ask you to specify the name of the instance, which could be a GUI limitation. As nobody has come across this crazy situation before hence there are no help in Google and metalink. However I have now managed to work out the process to do this.
To be honest it is not that bad as it sounds. If you ever come across this situation and would like to rename any ASM instance please read on ….. Logon to one of the ASM instance from a node and create a pfile from spfile.
Edit the pfile to change instance names. I only changed the following parameters in the pfile :. Shutdown the RAC database either through normal database shutdown procedure or server control srvctrl utility. Use server control srvctl utility to remove all database services and instances from OCR.
You may not have to do this though. Restart the ASM instance with the edited pfile created in step Create a new spfile from the pfile which will hold all the new instance names. I am assuming you hold you ASM sp file on a shared storage to be used by all the nodes in the cluster.
Shutdown the ASM instance which started earlier to create spfile. Now Start-up ASM instances on all nodes either through normal database start-up procedure or through server control srvctl utility. Add all services and instances to OCR which were deleted in step 4 using server control srvctl. NAME, df. Run the Create Scripts. Run catdbsyn. Run dbmspool. Please check spcpkg. Check the Logfiles: spcpkg. Level 0. This level captures general statistics, including rollback segment, row cache, SGA, system events, background events, session events, system statistics, wait statistics, lock statistics, and Latch information.

Create, View and Delete Snapshots. Create the Report. Statspack at a Glance. Here, we will review what we look for in the report, section by section. Statspack Report Header. Note that this section may appear slightly different depending on your version of Oracle.
Here, the item we are most interested in is the elapsed time. We want that to be large enough to be meaningful, but small enough to be relevant 15 to 30 minutes is OK.
If we use longer times, we begin to lose the needle in the haystack. Statspack Load Profile. The Hard parses we want very few of them. Transactions how many transactions per second we process. This gives an overall view of the load on the server. In this case, we are looking at a very good hard parse number and a fairly light system load 1 — 4 transactions per second is low. Statspack Instance Efficiency Percentage.
Next, we move onto the Instance Efficiency Percentages section, which includes perhaps the only ratios we look at in any detail:. All of these have to do with how well the shared pool is being utilized. Time after time, we find this to be the area of greatest payback, where we can achieve some real gains in performance.
If the library Hit ratio was low , it could be indicative of a shared pool that is too small , or just as likely, that the system did not make correct use of bind variables in the application. It would be an indicator to look at issues such as those. OLTP System. The way you achieve that is with bind variables. In a regular system like this, we are doing many executions per second, and hard parsing is something to be avoided.
