I have configured a flash recovery area of 9g yet the system keeps complaining that i have not enough flashback logs?
SPACE_RECLAIMABLE 1103842304
ESTIMATED_FLASHBACK_SIZE 45195264
the space_reclaimable is more than ESTIMATED_FLASHBACK_SIZE, so how is it possible the system always complain not enough space?

Server Administration :: Back Track OS Processes To RDBMS

View 4 Replies View RelatedRecovery Area Cannot Be Used For Archive Log?
Sep 13, 2013I`m using the the version 11.0.2.3 for testing. I read a line as below from the OCP book.
If none of the LOG_ARCHIVE_DEST_n parameters have been set, then transitioning. the database to archivelog mode will internally set LOG_ARCHIVE_DEST_10 to the flash recovery area, if it has been configured. In my database the fast recovery already been set as below.
SQL> show parameter db_recovery
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string +FASTRECOVERY
db_recovery_file_dest_size big integer 4248M
So I thought if I turn the database into archive log mode, then the log_archive_dest_10 will be set as the same value as db_recovery_dest.
SQL> alter database archivelog;
Database altered.
SQL> alter database open;
Database altered.
SQL> show parameter log_archive_dest
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest string
log_archive_dest_1 string
log_archive_dest_10 string
See, after the database become archive, the log_archive_dest_10 still be empty. So is there any thing wrong with my understanding?
Creating DB With Flash Recovery (Pros And Cons)
Mar 8, 2011I am moving an Oracle DB (10.2.0.1) to a new server, by creating a blank DB and importing the data by user. I chose to create the new database with Flash Recovery activated (I haven't previously used this), but I'm having a nightmare when importing the data.
I encountered issues with the DB_RECOVERY_FILE_DEST_SIZE which I resolved by increasing the size of this parameter.
Next the import crawled along because of redo.log file errors "Checkpoint cannot complete". I'm assuming that I need to add redo.log files to accommodate this?

View 1 Replies View RelatedSmart Flash Cache And Redo With SSD?
Oct 23, 201211.2.0.2.0
OEL.
Design stage of New SAN. I can put a lot of the database, including redo on SSD.
1. Hardware sub tiering enabled. Has anyone ever gauged performance with enabling 11g Smart flash cache using the SSD as the flash device even with the hardware subtiering on? ie, if the hardware subtiering is moving hotblocks to most performant disk, is there much significant benefit having the flash cache on. Im guessing yes as the flash cache is working at the SGA level.
2. To redo or not to redo on SSD. Many notes say not to so as to avoid log file sync waits. Is there a way to keep it on the SSD and avoid the waits? Is there any risk of enhanced degradation of the disks over time with having so much sequential writes from the redo if I leave it on there?

Exadata :: Dynamic Views For Flash Cache Usage?
Mar 19, 2013Despite it being one of the major selling points of Exadata (especially from X3 onwards), I'm struggling to find much information on our usage of the Exadata Smart FlashCache (I'm running RDBMS 11.2.0.2 BP7 on a V2 quarter-rack).
I can verify usage of the FlashCache by checking whether the object has been 'pinned' to the FlashCache via DBA_SEGMENTS and I can check for FlashCache usage by querying gv$sysstat (and even v$mystat), but are there other views that I could use? It seems a bit strange for Oracle not to provide the DBA all that much insight into their usage of this feature...
Enterprise Manager :: 11gR2 Grid Control - SVG Or Flash?
Sep 15, 2011I'm trying to use 11gR2 Grid Control to manage several 10gR2 database targets. I'm unable to determine the correct mix of Adobe software plug-ins to use for displaying SQL execution plans in a more graphical style. My client OS is Windows 7 - I have tried to research plug-ins for Internet Explorer 8, I upgraded (and subsequently downgraded!) to IE 9; I installed Firefox 6.x, tried with Google Chrome and all with the same results.
I'm not seeing any relevant information from MyOracle support or on Google, but may not be asking the correct question. As far as I can determine, SVG 3.0 is needed, Adobe stopped development in 2009 and there is no variant available therefore for Windows 7.
