Galer's "Maximum Performance"

Shortly after purchasing Elements 8 I also bought "Maximum Performance" by Mark Galer. For the most part it has been a great help to me although I have never discovered how to down load and use the presets he includes. I recently went to use the tutorals which I down loaded to my computer when I purchased the book as suggested, and found that I not longer have sound with the lessons. This is a real problem. Reviewing a process demonstrated in a tutorial with no sound is not very useful. I then tried using the programs directly form the DVD provided with the book and I have no sound form there either. Would anyone know if this is something that happens often with this publication? I have all the audio functions working on my computer which is fairly new. (Just over a year old with Windows 7) Can anyone help?

After downloading one of the videos for pse 9, it seems that quicktime works and plays sound whereas windows media player does not.

Real-time apply in Maximum Performance Mode Not Working

We have configured physical standby database in maximum performance mode. It's working perfectly fine. Archive logs are being applied to the physical standby.
We can open the DB in read-only mode, but real-time apply is not working. Physical standby database is lagging behind the primary db by an archive log. As soon as primary database generates an archive log, it's transported over to the standby and applied immediately by the media recovery process. But real-time redo is not working. Standby redo logs have been configured.
On Physcial Standby:

As you could see from the output above, value of transport and apply lag is equal to the elapsed time since last archive log switch.

Please advise.

Hi,
In your case you are using ARC process for redo transfer as you have not specified any process in log_archive_dest_2 and default is arch.
I will suggest you to use LGWR to transfer the redo to standby and also check the size of standby redo logs on standby is same to the size of online redo logs on primary

can anyone make it as regular query for maximum performance
Thanks,

Hi Sreekant,
Try this: If it helps
select g_com_bu_entity bunt_entity
, g_com_rep_cd srep_cd
, effdt from_dt
, eff_status
, g_com_role role
, g_com_pgm prgm
, g_com_district district
, g_com_draw_status draw_status
, decode(g_com_primary_pgm, 'Y',1, 0) pri_prgm_flag
FROM ps_g_com_assign_vw@commissions c1,
(SELECT MAX (effdt) effdt_max
FROM ps_g_com_assign_vw@commissions c2
WHERE c1.g_com_bu_entity = c2.g_com_bu_entity
AND c1.g_com_rep_cd = c2.g_com_rep_cd) t2
WHERE effdt = t2.effdt_max;

Can fast start failover be achieved in maximum performance mode

In a physical standby I would like to know if it is possible to configure High Availability in async mode to achieve fast-start failover? If so, please briefly describe how. Thanks

I've always said, size doesn't matter to Data Guard except when you are creating a standby database. After that it is the amount of Redo that is generated by the Primary database. A failover is a failover, for a 10GB database or for a 60TB database. The scary part is having to get the old Primary back up as a standby as quickly as possible.
Of course if the original Primary is completely toast then you have to recreate it with a new backup of the new primary or use a backup of the original Primary that happens to be on the Primary system and restore it as a standby and let Data Guard catch it up with the current state of affairs.
But, if the original Primary is still intact then you can use flashback database to reinstate it as a physical standby with little effort and no major backup restores. And of course, that is one of the requirements of Fast-Start Failover (FSFO). To enable it you have to have flashback database enabled on both the Primary and the FSFO target standby. Since enabling FB Database requires the database to be at the mount state I would suggest you enable it right after the upgrade to 11g.
When FSFO triggers a failover after a failure of the Primary, the Observer will automatically re-instantiate the failed Primary as a standby when it is started again and then it will be resynchronized with the new Primary automatically by Data Guard as normal.
The only difference between Maximum Availability FSFO and Maximum Performance FSFO is that you have to decide how much data you are will to lose when a failover occurs and tell the Broker by configuring the FastStartFailoverLagLimit property (see section 9.2.12 of the Broker manual).
You also want to be sure to place the Observer on a system where it is not affected by the Primary or Standby server going down or a network break between the Primary and the Standby. And if you can, use Grid Control. When you enable FSFO in Grid Control (on the Data Guard home page) you can specify 2 systems where the Observer can live. If it goes down on the original system an atempt will be made to restart it there. If that system if no longer available then Grid Control will attempt to start a new Observer on the 2nd system.
I would highly recommend you read the section [5.5 Fast-Start Failover|http://download.oracle.com/docs/cd/B28359_01/server.111/b28295/sofo.htm#i1027843] for lots of good information. And of course, the [Data Guard 11g Handbook|http://www.amazon.com/Oracle-Guard-Handbook-Osborne-ORACLE/dp/0071621113] (sorry, still plugging the book :^)

Maximum Availability to Maximum Performance.

steps to change from Maximum Availability to Maximum Performance.
SQL> select protection_mode from v$database;
PROTECTION_MODE
MAXIMUM AVAILABILITY
we need to come down to maximum performance mode due to some performance issues..any suggestions for the steps?

Hi Raman,
Perform below steps:
1) shutdown immediate
2) Startup mount
3)SQL> ALTER DATABASE SET STANDBY DATABASE TO MAXIMIMUM PERFORMANCE;
4)SQL> ALTER DATABASE OPEN;
Note: Issue all these commands on primary server
Hope this should work

Laptop + nvidia twinview = maximum performance level

I'm using 285.05.09 drivers. Whenever I connect my second monitor to my laptop nvidia PowerMizer scales the performance to maximum, which makes the laptop noisy, although I don't need it.
Has anyone else encountered this bug ?

Not a bug. Driving two displays requires higher bandwidth, and that can only be achieved by upping the performance level.

Best practice for maximum performance

Hi all
OS : Linux AS 4.2
Oracle 9.2.0.8
My database size is around 4TB (Every day increasing 5GB) and we are following a method like analyze the main table's latest partitions only because the entire statistics collection will take more time. Is that a good practice?
Is there any difference between analyze table command and using dbms_stats package to collect statistics?
Collecting entire statistics or estimate 33 % or 15% will make any difference (Performance level)?
Indexes are one of the main factors which will effect to the database performance. As a DBA, what all the things I should do in a daily basis to maintain indexes in a proper state.
I just wanted to know a best way of managing the statistics and indexes properly
Many thanks in advance

it depends, as always. If you have (important or large) queries that rely on global-level statistics then the statistics generated by "aggregation" (provided you've complete statistics on partition-level) might be insufficient, or they might become more and more outdated if you've generating them once and don't update them any longer (provided you're using DBMS_STATS, ANALYZE is not capable of generating genuine global-level statistics).
Note that 11g offers here a significant improvement with the "incremental" global statistics. See Greg Rahn's blog note about this interesting enhancement:
http://structureddata.org/2008/07/16/oracle-11g-incremental-global-statistics-on-partitioned-tables/
>
Is there any difference between analyze table command and using dbms_stats package to collect statistics? Definitely there are, more or less subtle ones. Regarding the partitioning, as already mentioned above, DBMS_STATS is capable of generating "real" top-level statistics at the price of "duplicate" work (analyzing the table at whole potentially reads the same data again that has been used to generate the partition-level statistics), but see the comment about 11g above.
There are more subtle difference, e.g. regarding the calculated average row length, etc.
>
Collecting entire statistics or estimate 33 % or 15% will make any difference (Performance level)?It all depends on your data. 1% might be sufficient to get the plans right, but sometimes even 33% might not be good enough. 11g adds here another significant improvement using a cunning "AUTO_SAMPLE_SIZE" algorithm that seems to get it quite close to "computed" statistics but taking far less time:
http://structureddata.org/2007/09/17/oracle-11g-enhancements-to-dbms_stats/
Indexes are one of the main factors which will effect to the database performance. As a DBA, what all the things I should do in a daily basis to maintain indexes in a proper state. B*tree indexes should in general be in a good condition without manual interference, there are only a few circumstances where you should consider performing manual maintenance. And most of these can be covered by the "COALESCE" operation, an actual "REBUILD" should not be required in most cases.

Best practices for maximum performance of C# CLR scalar UDF in View

Can anyone give some tips for best performance of a C# CLR UDF on SQL 2008 R2 or SQL 2012? Including maximizing the performance of the transition to CLR. I am using it in a View. E.g.,
create myview (id, name, address) as select id, dbo.MyUDF(name), address from mytable;
In particular:
Are there any specific C# build options or source code options? The MyUDF prototype is defined as:
[Microsoft.SqlServer.Server.SqlFunction()]
public static SqlString MyUDF(SqlString data)
Is it better to build the DLL for target x64 or Any CPU?
Does the use of a specific Target Framework have any effect? (e.g., DotNet 3.5 versus DotNet 4.0 or 4.5)
Is there any way to inform SQL Server that the UDF is safe for Parallelism?
I read somewhere that using the InProc ado.net Provider might improve performance but I don't see any mention of a Provider in the documentation for Create Assembly.
Thanks for any tips.

* Does the use of a specific Target Framework have any effect? (e.g., DotNet 3.5 versus DotNet 4.0 or 4.5)
Yes, if you select 4.0 or higher, the assembly will not load on SQL 2008 R2.
* Is there any way to inform SQL Server that the UDF is safe for Parallelism?
User-defined functions (save for inline) in general is a good recipe if you want to make sure that there is no parallelism. That is, the answer to your question is no, and if there is, SQL Server does not care.
* I read somewhere that using the InProc ado.net Provider might improve performance but I don't see any mention of a Provider in the documentation for Create Assembly.
Not sure what you mean here, but if you mean the context connection, this is in your code, and have nothing to do with what you put in CREATE ASSEMBLY. Except that, if you connect by some other means than the context connection, the assembly needs to have
EXTERNAL_ACCESS_PERMISSION. But are you really doing data access from your UDF?

How to charge a battery to optimize maximum performance

This is a general question on how to charge your laptop battery perfectly.
I heard people saying that charged your battery till 98-99% then remove the charger
Some said that it is not harmful to remove the A/C even if the battery is fully charged.
What is the best way from the above two.
Thanks.

Charge it until it is fully charged. See the following:

MOVED: How To Reach To The Maximum Performance with this Hardware ?

This topic has been moved to Overclockers & Modding Corner.
https://forum-en.msi.com/index.php?topic=143252.0

If the two disabled cores are stable then unlocking them should give a nice boost. To do this, go into the BIOS and enter the 'cell menu'. Find the option that reads 'CPU Core Control' and enable it. Next, go into Windows and download the 'BIOS Code Unlocked Technology' utility from >>here<<. You'll need to run the utility, enable the cores and reboot your computer. If the disabled cores are stable you should be able to boot up and see the two extra cores being utilised in Task Manager.
I'd advise you switch off the OC switch and see what you think of the new performance from having the two extra cores enabled, provided they're unlocked successfully.
No point overclocking the onboard graphics. If you want to play games then it's much better just to buy a dedicated PCI-E graphics card instead.
From an overclocking point of view, that power supply doesn't look too good so I wouldn't recommend overclocking personally.

To convert standby from maximum performance to maximum availability

Hi,
I have configured a standby to primary (version:10.2.0). But it is in maximum protection mode. When a logswitch has been done then it is applied at the standby site.
Now I want to convert to maximum availability such that any updation should be applied at the standby.
Can I get the procedure, how should it be done.
thankyou
satyanag

hi
First add standby logfiles to database then follow these commands..
1. set LGWR,SYNC and AFFIRM attributes in the archive destination on primary database.
2. issue this command on primary in mount stage.
ALTER DATABASE SET STANDBY DATABASE TO MAXIMIZE AVAILABILITY
3. Then go to standby ..issue this command...(assuming standby in shutdown mode)
a.startup nomount
b.alter database mount standby database.
c. Alter database recover managed standby database using current logfile;
this last command will not return the cursor..it keeps running....
Now u can check by creating a table on primary ...In case any more detail required then please post the message..
hope it works for u..

Maximum Performance gain for 10g Rel 2 on Win2003

Hi All,
For a 4 CPU Widows 2003 Adv Server m/c with 10g Rel 2 , 8G RAM, SGA_TARGET = 1.4G,PGA_TARGET= 1.4G which runs Procs involving expensive queries and lots of INSERTS (ETL jobs), what should be the value of PARALLEL_MAX_SERVERS , currently I have given it as 4 (as against 80 which is the default), through the 10g DB Control dashboard I can see only 26% CPU utilization.All my data files are in just 1 partition, do I need to have more disk partitions etc.
Do advise ....how can I have the maximum perf. gain out of the setup.
Regards,
Gaurav S.

Just to add , we have implemented RAID 6 on the Server m/c (its a 8 disk 1TB hard disk)

Recertified E4200 V1 or V2 maximum performance?

As stated above which one is the better buy?
Thanks

And to add the E4200 V2 supports Linksys Smart Wifi so you have the option to use either classic or the Smart Wifi firmware. But just in case you need this feature, E4200 V1 has both Internet Access Policy and Parental Controls but the E4200 V2 only has Parental Controls.
