Help! no response when doing SIMPLE query!

I meet a strange problem when I do a SIMPLE query on a table in Oracle 8.1.7, just like:
SELECT id FROM person WHERE id='12345';
Most of id values are ok to the query, except some values.
Whether I use these values in sqlplus or JDBC, mostly, no response is returned!! And I find the session in Oracle always keeps the status 'Active'. But in few scenario I can get the result quickly.
I don't know the reason. Help me please!
Thanks a lot!
Meyor

I'm not sure if the 'id' column contains something else.
When I shutdown and restart the database, the problem seems to be "solved". If the problem reoccurs again, I will try to use xTRIM functions.
Thanks!

Function/Procedure help - just want to build simple query and show results

I'd like a simple "histogram" function - perhaps there is one built-in I'm not aware of. I just want to count discrete values of a column. So I'm constantly writing queries of the form:
select column_name, count(*)
from table_name
group by column_name
order by column_name;
and I'm trying to write a function that will allow me to just type:
execute whatever(column_name, table_name)
or select whatever(column_name, table_name) from ?
and get the equivalent results from the query above.
How do you, or can you, write a procedure to take column/table names as inputs, substitue them into a query, execute the query and just display the results of that query? As I'm trying to figure out how to do this via google search, I keep going down rabbit holes of creating temporary tables/data types/records/refcursors etc. and I can't get any of it to compile. I'm not a DBA or SQL expert, so I'm hoping there's a simple way to accomplish this (without having to store and then process the "results" one row at a time)

If I understand the requirement correctly, a simple pipelined function will do it:

MMP using wrong search base when doing LDAP query.

Hi all,
I installed a new MMP (sun java communication suite v5 on Redhat linux x86).
When an imap user connects to MMP, the MMP does an ldap query for attributes "MailHostAttrs mailHost".
This query fails because the search base is
SRCH base="dc=my,dc=domain,dc=com,o=my.domain.com"
instead of simply "o=my.domain.com"
When I ran 'configure' I specified the Organization DN to be o=my.domain.com
And I've specified the following in the ImapProxyAService.cfg file:
LdapUrl "ldap://ldap1.my.domain.com:389/o=my.domain.com"
UserGroupDN "o=my.domain.com"
DefaultDomain my.domain.com
So why does it use "dc=my,dc=domain,dc=com,o=my.domain.com"?
I must be missing something but I can't find it.

Hi,

So why does it use "dc=my,dc=domain,dc=com,o=my.domain.com"?
I must be missing something but I can't find it.The first step the MMP will do to resolve the base DN for a hosted domain is a directory search along the lines of (this is for schema 2 which is the default for a new install):
[26/Oct/2007:16:46:23 +1000] conn=3152 op=1 msgId=2 - SRCH base="dc=aus,dc=sun,dc=com" scope=2 filter="(&(objectClass=sunManagedOrganization)(|(associatedDomain=aus.sun.com)(sunPreferredDomain=aus.sun.com)))" attrs=ALL
So in my case I have default:LdapUrl "ldap://server.aus.sun.com/dc=aus,dc=sun,dc=com" and default:DefaultDomain aus.sun.com
So you will probably find that you have a hosted domain configured under "dc=my,dc=domain,dc=com,o=my.domain.com" which got created during installation but not propagated with users.

SIGSEGV when running simple query

I hope this is the right place to report/ask for help, if not, tell me please.
When trying DB XML (version 24.16) I've managed to get this nasty
segfault. It happened when I've changes starts-with() to ends-with()
XQuery function in my query. I've defined a substring node index for the
element the function is applied to.
Followin is the only the start of the stack trace, I'll provide full log and every
addotional information I can get if it can help to solve this problem.

See this link for some formatting tips:

It's the link off the FAQ in the upper right of this page.
I can get your container but what I'd need is more specifics on the variable string being used and the actual query that fails. The ones above won't parse so it's not really clear what you intend.

Oracle 8i giving slow response when running sql query

hi ,
i am using oracle 8i server ;
and sql query giving slow response before some days;
so which parameter need to increase
DB_BLOCK_BFFERS OR SHARE_POOL_SIZE
CURRENT SETING IS
DB_BLOCK_BUFFER=256000;
SHARE POOLSIZE=300M;
pls advice to me
thanks

No parameters need to be increased. Tuning is not done but making arbitrary changes to values and hoping that good things will happen by accident.
The thing you really should be worrying about is your antique database and likely its impact on your skill set unless you are one year away from retirement.
Where's the actual version number?
Where's the DDL?
Where's the DML?
Where's the Explain Plan?

Console hanging when doing LDAP query

Hi,
I am able to connect to a test LDAP server (that has 10 users) from WLS and am
able to see the users in Web interface of the Console under Security>realms>myRealm>users.
This works as desired. No problem.
But when I try to connect to an LDAP server that has 1900 users the console hangs
up and eventually times out. The query strings are all fine because I verified
them using an external LDAP browser.
I checked in MyTestServer>Monitoring>Performance and it is using only 25% of the
memory. So it is not a memory issue. Then I set the logging threshold to 'info'
but there are no special messages.
Now I am wondering where else should I look for to fix this. It works fine when
there are small number of users. But when there are large number of users, WebLogic
just hangs...
Thanks,
Dan

WLS build from BEA comes with SP1. This is what I am using at the moment. So I
am not sure what SP1 are you referring to!
The SP1 for Platform is yet to be released though. But this is more of a server
issue (I think). Also, I looked up in the 'known bugs' section. This is not listed
in there...
* Do you know what exactly is causing this problem?
* Is there a work around?

Flash Freezes when doing simple Shape Tween

I tested this in Flash 5 before I brought it over to Flash
CS3 and am very concerned about the results.
I have an object that has been created on the stage and is
not a library item. I am creating an animation with no action
scripting that will be converted to a mov file and the end use will
be a video played on tv.
I have three keyframes, spaced out at 1, 5, and 10 frames.
Frame 10 has 10 nodes in the object, frame 5 has 8 nodes, and frame
1 has 7 nodes. I put my playhead on any frame in between the
keyframes, and cntl+click for the pop-up menu, from which I select
'Create Shape Tween'. Flash creates the tween, but when I attempt
to save or move the playhead (with either the 'return' key or the
short cut keys) the program throws up the 'beach ball' which spins
for over 5 minutes, making me 'force quit' the application.
Other aspects of this project are that I have several layers
(all of which are hidden [the 'eye' turned off] during testing),
contained in a folder. No other animation has been applied to any
other objects.
I am running an iMac with version 10.4.11 and have had no
other problems with the application.
Is there a fix I can download? This seems to be a programming
problem.
Thank you for your help.

Flash software has a major problem with some of the new
tools, such as the Gradient Transform tool.

Macbook Pro Retina CPU Overheating when doing simple tasks?

I've had my Macbook Pro w/ Retina since July 2012 and for about a month now (starting in November) the CPU Die - Digital has been getting EXTREMELY overheated. It has gotten up to 210 degrees F which is way past the damaging level of CPU but the real kicker is that it happens when I have a few tabs open in safari and a couple other minor programs open (Mail, Finder, App Store, Skype, iTunes). It's not like I'm running Skyrim, LoL, and Starcraft while running background tasks in Fincal Cut X and Motion V?? I mean I have 16GB of ram and only 5 or 6 of it is in use so it's not a problem with multitasking and processing power also shouldn't pose much of a threat for a few tabs in a browser and some low usage programs. I use iStat Menu's and I took a screenshot just now of it in the 180's when it was recently in the 190's. I also checked the disk utility and I can't see anything in the CPU usage that would make it work that hard.
My questions are am I doing something wrong? Is there something I'm missing? Is my laptop defective and in need of refurbishing using Apple Care? Is this happening to anyone else?
Thank you in advance.

Turn off Skype and see if that has any affect. Skype is is a notorious heat generator.
Did you check Activity Monitor?
Ciao.

Hi,
R-tree indexes were field test in 8.1.6. The error you are seeing doesn't look familiar in terms of fixes that were made for the first production ship in 8.1.7.
You should try upgrading, and it should be fine.

Fans going insane when doing simple tasks and playing WoW?

Hello. I've been playing WoW, starting a new character last week. Until the other day, I could play fine. But starting the other day, the fans would all of a sudden rev up like I've never heard before. My laptop is very powerful, and far surpasses the recommended requirements.
However, when the fan goes crazy, even if I quit the game, and let it stay at my desktop, the fan is still going insane. And I even set all the graphical settings in WoW to the lowest, but it still makes a very loud noise.
And I've owned many laptops with graphic intensive applications running, and the fans never made this sort of noise. Any ideas what may be happening?

I checked my CPU monitor, and my CPU usage is averaging 1-3% at most. And it's been almost half an hour since I quit the WoW application. I even tried restarting. I'm running on the Windows side right now, and my mac side doesn't have any 3rd party drivers or anything installed on it.
On the windows side, I quit processes related to my gaming keyboard and mouse macro programs, since all I do on Windows 7 (in Boot Camp) is play video games. And for the past week I was able to play Mass Effect, without the fan making this noise, and Mass Effect is 10x more demanding than WoW.

What does it mean when the usecounts of Parse Tree for a view is incrementing when a select query is issued against the view?

I'm using SQL Server 2008 R2 (10.50.4033) and I'm troubleshooting an issue that a select query against a specific view is taking more than 30 seconds consistently.   The issue just starts happening this week and there is no mass changes in data.
The problem only occur if the query is issued from an IIS application but not from SSMS. One thing I noticed is that sys.dm_exec_cached_plans is returning 2 Parse Tree rows for the view - one created when the select query is issued
1st time from the IIS application and another one created when the same select query is issued 1st time from SSMS.   The usecounts of the Parse Tree row for the view (the IIS one) is increasing whenever the select query is issued.  The
usecounts of the Parse Tree row for the view (the SSMS one) does not increase when the select query is issued again.
There seems to be a correlation between the slowness of the query and the increasing of the usecounts of the Parse Tree row for the view.
I don't know why there is 2 Parse Tree rows for the view. There is also 2 Compiled Plan rows for the select query.
What does the Parse Tree row mean especially the usecounts column?

>> The issue just starts happening this week and there is no mass changes in data.
There might be a mass changes in the execution plan for several reason without mass changes in data
If you have the old version and a way to check the old execution plan, and compare to the new one, that this should be your starting point. In most cases you don't have this option and we need to monitor from scratch.
>> The problem only occur if the query is issued from an IIS application but not from SSMS.
This mean that we know exactly what is the different and you can compare both execution plan. once you do it, you will find that they are no the same. But this is very common issue and we can know that it is a result of different SETting while connecting
from different application. SSMS is an external app like any app that you develop in Visual studio but the SSMS dose not use the Dot.Net default options.
Please check this link, to find the full explanation and solutions:
http://www.sommarskog.se/query-plan-mysteries.html
Take a look at sys.dm_exec_sessions for your ASP.Net application and for your SSMS session.
If you need more specific help, then we need more information and less stories :-)
We need to see the DDL+DML+Query and both execution plans
>> What does the Parse Tree row mean
I am not sure what you mean but the parse tree represents the logical steps necessary to execute the query that has been requested. you can check this tutorial about the execution plan: https://www.simple-talk.com/sql/performance/execution-plan-basics/ or
this one: http://www.developer.com/db/understanding-a-sql-server-query-execution-plan.html

Simple query help in plsql - help

oracle version : 10gR2
indexes are created on each column, is there anyway to make them used while searching for the records rewriting the following query to test given data in any case (lower ,upper)...
SELECT * FROM TX_USERS
WHERE userid like decode( UPPER('Md'),null,userid, UPPER( 'MD')||'%' ) and
first_name like decode(UPPER('Na'),null, first_name, UPPER( 'NA')||'%' ) AND
LAST_name like decode(('Ra'),null, LAST_name, UPPER('RA')||'%' )
-- list goes on..
UPPER('Md') -- is the input values comes from form.. for example i_userid.. this query works fine .. is there anyway of getting indices used without using functional based indexing when we rewrite query like shown below??? input parameter valeus can be anything and table column values can be anything i.e. anycase (upper or lower or mix of both)..
actual code would be
upper(userid) like decode( UPPER(i_userid),null,userid, UPPER( i_userid)||'%' ) and
upper(first_name) like decode(UPPER(i_first_name),null, first_name, UPPER( i_firstname)||'%' )
if we put upper(userid) then index not used ..........anyway of rewriting using it or any other technique... or any other new way

No, its not working... see the below..
create table test5 as select owner, object_name, subobject_name, object_type from all_objects;
create unique index test5_i5 on test5 (owner, object_name, subobject_name, object_type);
select * from test5 where owner like 'SCOTT' AND OBJECT_NAME LIKE 'EMP';
INDEX RANGE SCAN| TEST5_I5 | 4 | 248 | 1 (0)| 00:00:01 |
but when i use
select * from test5 where UPPER(OWNER) LIKE 'SCOTT%' AND UPPER(OBJECT_NAME) LIKE 'EMP%';
TABLE ACCESS FULL| TEST5 | 3 | 186 | 65 (5)| 00:00:01 |
i know it goes to full scan, i want to know is there any other way to make index used .. without using functional based indx...
the reason is user can search any one of the column data and data is mixed case in table columns and/or conditions specified in query..
.. any help...
