Ksfd: async disk IO
Could anyone shed more light on the parameters a) count b) intr and c) timeout on this 10.1.0.5 wait event?
This is from information in the v$event_name table.
HKT
Thanks Alan. That was a very helpful link. More detailed information for ksdf:async disk IO was listed in note 170357.1.
P1 = count
P2 = intr / aioflags
P3 = timeout
Note: In 9.0 all parameters are shown as 0 if "intr" is false (0).
count Number of IO requests being waited for. This is the number of IO requests we are waiting to complete. (or 0 in 9.0 if intr == 0)
intr / aioflags
9.0Interruptable
9.2 AIO Flags
In 9.0 this is non-zero if the process is also postable while waiting for the IOs to complete.
In 9.2 this is a set of flags thus:
0x00 Wait for all IO types non interruptable
0x01 wait is interruptible
0x02 Ignore IOs submitted via the OSD interface
0x04 Ignore ODM IOs
0x08 Ignore OSM IOs
0x20 Wait for new i/o completions
timeout Timeout in centi-seconds
Timeout in centi-seconds. (or 0 in 9.0 if intr = 0)
Thanks again,
Harold

I am on 11.1.0.7 on AIX.
My Database as well as OS is set for Aysnc IO.
My App server where my ETL tool (Informatica) is being installed is also set for Aysnc IO.
But while doing an load (INSERT) from Informatica to the database table, I see a lot of waits for "ksfd: async disk IO".
Background of this load is that the team first truncate the table and load the data on to this table using informatica. It's a load of just 200,000 rows but taking around 20 mins.
Question -
1. What does this wait "ksfd: async disk IO" really mean?
2. Is it a sign of bad sign from performance perspective?
3. If yes, then how to make sure that I don't get these waits?
Thanks!http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1257800375707

Edited by: steffi on Mar 20, 2011 8:19 AMText can be formatted by tagging the beginning and end of the block of text with the code ta
\Formatted text goes here.
\Example:
This is formatted.When cutting and pasting text such as execution plans, excerpts from AWR reports, etc, it will maintain spacing and formatting, and make for much easier reading.
As to the content, well, dumping the contents of v$system_event is pretty close to useless.
As to the first three events you listed, 'enq: TX - index contention', 'enq: TX - row lock contention', 'enq: SQ - contention', well, all of those are easily tunable.
First, for 'enq: SQ - contention', check your sequences. Do you have any NOCACHE sequences? Or sequences with small caches?
As for 'enq: TX - row lock contention', well that's fairly self-explanatory. You have multiple sessions trying to lock the same row in the same table at the same time.
Last, 'enq: TX - index contention', that's non-row level contention on an index. For example, if you have a unique index, insert a row w/ column value 1, but don't commit, then try to insert that same value from another session.
But, before you do any of that, I think you need to clearly understand where the bottlenecks are. Try taking some AWR snapshots, about 5 minutes apart, when you're having performance problems. Look at the AWR report for that 5 minute period. In particular, look at your Top 5 timed events.
Hope that helps,

Hi,
I'm seeing async disk io event while doing rman operation (backup, validate backupset) and the rman session is waiting long on this event.
any suggestions / inputs on this.
Thx,
-KarthicKIf SEQ# in V$SESSION or V$SESSION_WAIT was changing, then it was a new occurrence of a wait each time.
You have to look at STATE and WAIT_TIME as well. If STATE is WAITING , then SECONDS_IN_WAIT is the current wait. If STATE is anything else, then WAIT_TIME is the the previous wait.

End of ReportFrederic's right... you're summing up too many statspacks ..
Can't see anything specific apart from the fact that Statspack itself is showing up in the top statements.
First : define 'Slow' . What is your goal for 'Ok' ?
Start thinking about sql_trace, tkprof and 10046 traces -
Hai
We are using oracle 9i R1.
I used to run statspack report every one hour.
Go through the following report and let me know what is wrong in this report. Because our server getting very slow day by day.
Mostly I changed.
If you find anything wrong in the server parameter defined, please let me know to correct that.

- not using bind variables anywhere, resulting in excessive statement parsing. All of your statements have hardcoded literals, and many of those statements are identical except for the hardcoded literals.
Due to the hardcoded literals for Oracle they are different, and will be reparsed.
- excessive full table scans : 48 percent of the wait time is db file scattered read which means full table scan.
Time to tune your statements.

Performance issue showing read by other session Event
Hi All,
we are having a severe performance issue in my database when we are running batch jobs.
This was a new database(11.2.0.2) and we are testing the performance by running some batch jobs. These batch jobs included some inserts and updates.
I am seeing read by other session in top 5 timed events and cache buffers chains in Latch Miss Sources section.
Please help me to solve this out.

What are the best solutions for data warehouse configuration in 10gR2
I need help on solutions to be provided to my Client for upgrading the data warehouse.
Current Configuration: Oracle database 9.2.0.8. This database contains the data warehouse and one more data mart on the same host.Sizes are respectively 6 Terabyte(retention policy of 3 years+current year) and 1 Terabyte. The ETL tool and BO Reporting tools are also hosted on the same host. This current configuration is really performing poor.
Client cannot go for a major architectural or configuration changes to its existing environment now due to some constraints.
However, they have agreed to separate out the databases on separate hosts from the ETL tools and BO objects. Also we are planning to upgrade the database to 10gR2 to attain stability, better performance and overcome current headaches.
We cannot upgrade the database to 11g as the BO is at a version 6.5 which isn't compatible with Oracle 11g. And Client cannot afford to upgrade anything else other than the database.
So, my role is very vital in providing a perfect solution towards better performance and take a successful migration of Oracle Database from one host to another (similar platform and OS) in addition to upgrade.
I have till now thought of the following:
Move the Oracle database and data mart to separate host.
The host will be the same platform, that is, HP Superdome with HP-UX 32-bit OS (we cannot change to 64-bit as ETL tool doesn't support)
Install new Oracle database 10g on the new host and move the data to it.
Exploring all new features of 10gR2 to help data warehouse, that is, SQL MODEL Clause introduction, Parallel processing, Partitioning, Data Pump, SPA to study pre and post migrations.
Also thinking of RAC to provide more better solution as our main motive is to show a tremendous performance enhancement.
I need all your help to prepare a good road map for my assignment. Please suggest.
Thanks,

Regarding 'Direct Path Read' waits
As we all know, direct path read waits is a new feature in Oracle 11g. From Oracle Documents or others' articles, when it is full table scan, direct path read occured. But why it occured? I don't know clearly.
Below is Oracle Document description:
http://docs.oracle.com/cd/E18283_01/server.112/e17110/waitevents003.htm#sthref3849
During Direct Path operations the data is asynchronously read from the database files. At some stage the session needs to make sure that all outstanding asynchronous I/O have been completed to disk. This can also happen if during a direct read no more slots are available to store outstanding load requests (a load request could consist of multiple I/Os).
Question:
1. During Direct Path operations the data is asynchronously read from the database files. >> what does this statement mean? what's ''asynchronously read'?
2. describe above description for me in details.
3. who can clearly explain 'why direct path read waits occur' for me?
Thanks in advance.

If you want to get very technical, Frits Hoogland has written lots of stuff about the implementation:

How to set the correct shared pool size and db_buffer_cache using awr
Hi All,
I want to how to set the correct size for shared_pool_size and db_cache_size using shared pool advisory and buffer pool advisory of awr report. I have paste the shared and buffer pool advisory of awr report.
Shared Pool Advisory
* SP: Shared Pool Est LC: Estimated Library Cache Factr: Factor
* Note there is often a 1:Many correlation between a single logical object in the Library Cache, and the physical number of memory objects associated with it. Therefore comparing the number of Lib Cache objects (e.g. in v$librarycache), with the number of Lib Cache Memory Objects is invalid.
