30EA1: SQL History performance
when I press F8 to show sql history, the application performance become very slow,
happen to you?
Previously I thought it was just the SQL history window that was slow, but it turns out to be the whole app.
I found that doing a simple select returning 16 rows took ~2 seconds with SQL history off and ~7 seconds with it turned on.

30EA1 SQL History spikes cpu and hangs, un-usable
app works fine until I open the sql history (F8) , cpu spikes and stays above 50% until I close history window. As soon as I close it, the app is responsive again.
I have less than 1000 entries in the sql history window.
Has anyone else experienced this?There have been performance issues associated with having the SQL History pane open (30EA1: SQL History performance so if you have that open, you could try with it closed. Maybe that is bug 10233068 that gggraham referred to, but I couldn't find another reference to that bug on the forum and it is not a published bug.

Hi,
The SQL History from previous versions is not retained, but luckily not physically deleted either. It seems 3.0 has a new system? (If so, please remember to include it in the migration process before release!)
Thanks,
K.In my case I can see what looks like migrated SQL History (based on dates and content) but none of the new SQL statements are being shown. I could live without the migrated statements if I could get new statements to show up.

30EA2: Hangs on opening SQL History
Hi,
After EA1's pretty strong performance impact regarding SQL History, I was hoping for improvement in EA2.
However, after installing, migrating from 2.1.1, and setting preferences, I connected and selected the SQL History entry from the Edit menu. Then sqldev just hung with 50% CPU use (distributed over both cores), and never came back. After almost an hour I just killed it.
Right now I'm trying again; I just ran sqldev, and selected the SQL History entry from the Edit menu.
What's happening? Here's a dump if it helps:

Sorry guy, at this point I killed sqldev. I will skip further testing until EA3, in the hope that will address these issues.
I regret so much the history mechanism has changed. Why on earth did you guys do so?
Everything was so accessible and responsive... Now various users noted various problems.
Haven't you heard of the golden rule: "don't change working code"?
Why not take care of all recent issues and revert to as it was before?

Quantity of SQL History shrinking
I've noticed since about Dec. 2006 or Jan. 2007 that the quantity of SQL History kept has varied greatly and generally shrunk. In the last five days it has shrunk from 21 days to 10 days. I currently only have 47 entries in SQL History. I estimate that I execute a minimum of 20 unique queries every business day, so a significant number of my queries over the last 10 days are missing from SQL History.
In addition, today I'm noticing that I only have entries from a single database connection in SQL History. I have executed queries against two database connections today and at least 4 others over the last week. But only one of those database connections is reflected.
I've counted the entries in "SqlHistory.xml" and it matches the number of entries I see in the SQL History dialog.
Any ideas on what is happening to my SQL History? I am aware of the bug that can wipe out all of the SQL History prior to the time when a second instance of SQL Developer is opened. In this case though, I still have 10 days of history and history for all but one database connection is missing.
SQL Developer 1.1.2.25
Oracle 10g Enterprise Edition 10.2.0.2.0 - 64bit (all databases I access are the same version)
Java 1.5.0_05
Windows XP Pro SP2
132gb free space on the drive which has both Windows installed and SQL Developer.
Pentium 4 3GHz
2GB RamBill,
I assume this happened on htmldb.oracle.com. I bet one of our (necessary) cleanup jobs kicked in and purged some old statements.

How to get sql server performance counters using query?
Hai i want to see my sql server performance counters like, Full Scans/sec, Buffer
Cache Hit Ratio, Database Transactions/sec, User
Connections, Average Latch Wait Time (ms), Lock

Either the statistics are not up to date, the data values are skewed or you have some optimizer parameter set to none default to force index access.
Please post explain plan and optimizer* parameter settings. -
SQL Developer SQL History no longer working 3.2.20.09.87
Hi guys, The SQL History (F8) option has started to no longer work within my copy of OSD.
it was working at one point but has gone away.
I have confirmed that "Enable Local History" is enabled and has been set for 30 days history and 50 max revisions
I have confirmed that I still have a SqlHistory.xml file located in my user\operator\AppData\Roaming\SQL Developer\ directory with entries in it (6933 rows of data)
This started to happen after I started to play with the Garbage Collection settings to reduce the memory footprint of OSD.
I have since restored all of my backed up delivered settings, rebooted and the SQL History will not show up again.
My snippets and custom reports are working and I can still see the log detail where I used to see log and sql history options at the bottom of OSD.
I'm using Windows 7 and can provide an OSD dump if it helps.
Thanks...
Tom
Edited by: ERPDude on Mar 6, 2013 10:03 AMHi Tom,
Be careful about which preference settings relate to the functionality in question.

You do not say how you backed up and restored your settings during all your experimentation, but let's assume whatever you did was valid. Whenever some UI component mysteriously disappears, one thing I always check (usually just delete) is the windowinglayout.xml in system3.2.20.09.87\o.ide.11.1.1.4.37.59.48 of my user settings.
For example, I can use the SQL History pane's tab context menu to Float it, then adjust it's size by dragging it's edges down to a grey square a few pixels wide/high. Close SQL Developer, reopen, View > SQL History. Darn! Where did it go?
Hope this helps,

Hi
i have some question about SQL Loader. i have to find answers but did not get from Google or Documentation. i want to know that is there any way to check whether Sql loader inserting records with Direct path or Conventional path. As we know there are restriction in Direct load. Direct-path inserts do not support all objects that conventional inserts do. Their functionality
is restricted. If the database engine is not able to execute a direct-path insert, the operation is silently converted into a conventional insert. i have instruct Sql loader to insert using Direct=true and parallel as well. but it take 15 mint to loader 4 million record in table. i have observed its transfer rate is bit slow. i have oracle 11R2 on windows 2008 with 40GB RAM and SAN. how can i verify during execution either Sql loader load user Direct path or silently converted it conventional path. here is my sample control file. function used in control file will convert direct path to conventional?

How does Index fragmentation and statistics affect the sql query performance
Hi,
How does Index fragmentation and statistics affect the sql query performance

ShashikalaHow does Index fragmentation and statistics affect the sql query performance
Very simple answer, outdated statistics will lead optimizer to create bad plans which in turn will require more resources and this will impact performance. If index is fragmented ( mainly clustered index,holds true for Non clustred as well) time spent in finding
the value will be more as query would have to search fragmented index to look for data, additional spaces will increase search time.

T-SQL query performance (CLR func + webservice)
Hi guys
I have CLR function which accepts address as a parameter, calls geocoding webservice and returns some information (coordinates etc.)
I run SQL query
SELECT *FROM T CROSS APPLY CLR_Func(T.Address)F
Table contains 8 million records and obviously query runs very slow.
Do you know any nice way to improve performance in this situation?
Thank you,
MaxNo WHERE condition? SQL Server will call the function 8 million times ....

SQL History - returning wrong statement if history is sorted
I have searched the forum and not seen anything on this, but I have been getting the wrong SQL statement returned when I select Append/Replace.
I have statements going back to 12-Jan-06 (using 804 since 13-Jan-06, 796 since 12-Jan-06 and 715 last year), so I don't know if I have hit the aging limit or not (I think I counted 221 entries).
It seems to me that it works out the cursor position and then returns that statement number from the history - independently of resorting the history.
For example, if I sort from oldest to newest (based on timestamp) and then select the bottom statement (displays as newest) and Replace, I get the oldest statement in the worksheet. If I select the top statement (displays as oldest) and Replace, I get the newest statement in the worksheet.
This is further complicated by the fact that sorting on the Timestamp is doing an alpha-numeric sort, rather than a date sort. When sorting from oldest to newest, the bottom three timestamps are (in "oldest to newest" order) are:
1/23/06 10:58 AM
1/23/06 9:21 AM
1/23/06 9:31 AM
If I then remove the sorting, the statement returned is the correct one.It was great to get the fix for the SQL History returning the right statement if sorted (we got it in v1184).
However v1215 still does a text sort on the TimeStamp column rather than a date sort, so 2PM comes before 9AM, etc.
Also, where is the format for the TimeStamp column coming from? As someone who doesn't live in the US and thinks that days should come before months in date formats (ie DD-Mon-YYYY), I am frustrated by yet another product that uses MM/DD/YY, despite my best efforts at telling it otherwise. -
SQL Broker Performance Reports are empty
Good day,
I'm running SCOM 2012 SP1. I was requested to deliver a couple reports for an SQL migration/upgrade.
The relevant data is in The SQL Broker Performance Reports both for SQL 2008 and 2012.
I have been looking at troubleshooting article such as: http://support.microsoft.com/kb/2573329
And all my system configs are OK, as well as positive logs. I have reviewed overrides and enable all performance ovverides on SQL MP just to see if it was going to make a change. I added an MP from VEEAM (quite cool actually) thinking I would get better
results but that also failed.
Has anyone encountered this issue before. The funny thing is that other reports give data :-).
Is there something I need to enable further, am no SQL guru.
Best regards,
Dominique.Hi,
How about Clear the Cache for the SQL agent by following the below steps?
In the Monitoring workspace, expand Operations Manager and then expand
Agent Details.
Click Agent Health State.
In Agent State, click an agent.
In the Tasks pane, click Flush Health Service State and Cache
In addition, we may
1) stop scom agent Service (OPsMgr Health service)
2) rename forlder.C:\Program Files\System Center Operations Manager 2012\health service state.
3) start scom agent Service.
Hope this helps.

SQL History and timestamp order
Hi, I have SQL Developer 12.84 (4.0.0.12).
Sql history forces MM/DD/RR format in Timestamp instead of NLS format: DD.MM.YYYY HH24:MI:SS.
As a consequence the sort order fails.
Played with C:\Users\<user>\AppData\Roaming\SQL Developer\SqlHistory files but each new entry ignores manual date changes and writes timestamp in strange format.
Any idea?Already identified by developer team as:
Bug 17740406 - SQL HISTORY TIMESTAMP NOT SORTED AS DATE FOR NON-US LOCALES
Info based on: https://forums.oracle.com/thread/2601066 (why new thread)
This is important drawback in SQL Developer 4 for non US users. BTW, still not fixed in build 13.30 (4.0.0.13) -
EA3 - SQL History window refresh problem
Hi, I have noticed that version 1.2 (possibly farther back) up to and including 1.5 EA3 have a issue with refreshing the SQL history window in a special scenario.
If the tab is completely undocked from SQL developer and then expanded across two monitors, as I scroll down the parts of the data rows on the non-primary monitor are not refreshed and become jagged.
I am running SQL developer on Win XP SP2 with whatever version of Java came with EA3.Thanks, that seemed to work. It looks like Java is painting the grid in two parts now, with the non-default monitor side being second, but at least it repaints.
As far as a default, I did already have the following option in the config file:
AddVMOption -Dsun.java2d.ddoffscreen=false
I don't what difference the -J option makes but that's what I had. Thanks again.
