SLOW query PERFORMANCE

We live a very slow performance for the below query. Joined the explain command plan too. One of us can, help us with suggestions. We expect something as nested loops could be avoided by following certain steps, some changes in the structure of the query.

SELECT assoc.name_first. ' ' || Assoc.name_last AS client_manager
T1 assoc,.
This T2,
T3 aa,
Law on the T4
T5 cc
WHERE ce.ent_id = act.primary_ent_id (+)
AND ce.ent_id =: p_ent_id
AND assoc.id = CASE WHEN aa.assoc_id IS NULL THEN (SELECT DISTINCT ca.assoc_id
From t6 ca
WHERE ca.comp_id =

AND
CA.cd_code IN
("CMG", "GCR",
"BCM", "CCM"
'BAE'))
Of OTHER aa.assoc_id
END
AND nvl (act.activity_id, 0) = nvl (aa.activity_id, 0)
AND assoc.bk_code = cc.cpy_no
AND assoc.center = cc.cct_no

I appreciate your time and efforts.

Maybe try this

SELECT assoc.name_first || ' ' || assoc.name_last AS client_manager
  FROM t1 assoc,
       t2 ce,
       t3 aa,
       t4 act,

   AND ca.comp_id = ce.ent_id
   AND ca.cd_code = aa.role_code
   AND assoc.id = nvl(aa.assoc_id, ca.assoc_id)
   AND assoc.bk_code = cc.cpy_no
   AND assoc.center = cc.cct_no
   AND (act.activity_id = aa.activity_id OR (act.activity_id is null and aa.activity_id is null))
   AND aa.role_code IN ('CMG', 'RCM', 'BCM', 'CCM', 'BAE')

Untested code. Pleace in order to check if it gives the correct result.

Query performance poor when they join CONTAINS to another table

We just recently started evaluation Oracle Text for a search solution. We must be able to find a table which can have over 20 million lines. Each user can have visibility to a very small part of these lines. The goal is to have a single Oracle text index that represents all the columns of research in the table (multi column datastore) and provide a score for each search result so that we can sort the search results in descending score order. What we see is that the performance of the queries of TOAD are extremely fast, when we write a simple CONTAINS query against the table indexed Oracle text. However, when we first try reduce the lines from that CONTAINS query must search using a we find the query performance degrades significantly.

For example, we can find all the records that a user has access from our base table of the following query:

SELECT d.duns_loc
DUNS d
JOIN primary_contact pc
ON d.duns_loc = pc.duns_loc
AND pc.emp_id =: employeeID;

This query may run in < 100 m in the example, this query returns close to 1200 lines of the duns_loc of primary key.

Our search query looks like this:

SELECT score (1), d.
DUNS d
WHERE CONTAINS (TEXT_KEY,: research, 1) > 0
ORDER BY score (1) DESC;

The: Find value in this example will be 'Highway '. The query can return 246 k lines in about 2 seconds.

2 seconds is good, but we should be able to have a much quicker response if the request did not have to search the entire table, right? Since each user can only records from 'view' that they are assigned to as us if the search operation had to be analysed a tiny tiny percentage of the TEXT index, we should see results faster (and more relevant). If we now write the following query:

WITH the subset
AS
(SELECT d.duns_loc
DUNS d
JOIN primary_contact pc
ON d.duns_loc = pc.duns_loc
AND pc.emp_id =: employeeID
)
SELECT score (1), d.
DUNS d
JOIN the subset s
ON d.duns_loc = s.duns_loc
WHERE CONTAINS (TEXT_KEY,: research, 1) > 0
ORDER BY score (1) DESC;

For reasons that we have not been able to identify this query actually takes longer to run than the sum times the contributing elements. This query takes more than 6 seconds to run. We, or our DBA can understand why this query runs worse than a large open research. Open research is not ideal because the query eventually folders back to the user, they do not have access to view.

Has anyone ever encountered something like that? Any suggestions on what to watch or where to go? If someone wants more information to help diagnosis to let me know, and I'll be happy to produce it here.

Thank you!!

Since you're using two tables, you will get probably better performance on an index that uses a section group and a user_datastore that uses a procedure. He should be able to recover all the data with a simple query, and hit a single index. Please see the demo below. Indexing can be slower, but research should be faster. If you have your primary and foreign keys in place and current statistics before you create the index, it should speed up indexing.

The BLASTP_ALIGN query performance decreases as increases the size table Ref?

Newbie here.
I'm using Oracle 11.2.0.3.
I am currently running and a loop through the cursor according to who uses the tool BLASTP_ALIGN from Oracle:
FOR MyALIGN_TAB IN
(
Select a.query_string, H.AA_SEQUENCE target_string, t_seq_id, pct_identity, alignment_length, incompatibilities, positive, gap_openings, gap_list, q_seq_start, q_frame, q_seq_end, t_seq_start, t_seq_end, t_frame, score, wait
from (select t_seq_id, pct_identity, alignment_length, incompatibilities, positive, gap_openings, gap_list, q_seq_start, q_frame, q_seq_end, t_seq_start, t_seq_end, t_frame, score, wait
table (BLASTP_ALIGN ((p_INPUT_SEQUENCE SELECT query_string FROM DUAL),
CURSOR (Select GB_ACCESSION, AA_SEQUENCE from HUMAN_DB1. HUMAN_PROTEINS),
1-1, 0, 0, 'PAM30',. 1, 10, 1, 2, 0, 0)
)
),
(SELECT p_INPUT_SEQUENCE FROM DUAL Query_string).
HUMAN_DB1. HUMAN_PROTEINS H
WHERE UPPER (t_seq_id) = UPPER (H.gb_accession) and gap_openings = 0
)
LOOP

This initial query works relatively well (about 2 seconds) on a table target of approximately 20,000 documents (reproduced above, as the HUAMN_DB1. Table HUMAN_PROTEINS. However, if I had to choose a selected target table that contains approximately 170 000 records, the query performance are significantly reduced in about 45 seconds. The two tables have identical ratings.

I was wondering if there are ways to improve the performance of BLASTP_ALIGN on large tables? There only seems to be a lot of documentation on BLASTP_ALIGN. I could find this (http://docs.oracle.com/cd/B19306_01/datamine.102/b14340/blast.htm), but it wasn't that useful.

Any ideas would be greatly appreciated.

In case one is interested... it looked like the AA_SEQUENCE column in the following slider: SLIDER (Select GB_ACCESSION, AA_SEQUENCE from HUMAN_DB1. HUMAN_PROTEINS) was a CLOB field. In my second target, my column correspodoning table was VARCHAR2. One hypothesis is that BLASTP_ALIGN made a VARCHAR2-> CLOB conversion internally. I changed the table to have a CLOB column and with success against BLASTP_ALIGN 170 000 documents about 8 seconds (not much, but better than 45).

I will mark it as answered.

Very slow network performance

I have a Dell T610 running ESXi 4 with a pair of built in maps network gigabit Broadcom BCM 5709, to which I've also added a gigabit dual port Intel 82576 NIC they are all plug a Cisco 3560 24 ports switch. There are a couple of virtual machines on this computer and there was near zero, a network, or activity of the CPU during the following tests as they were made during off-peak hours.
I noticed a few updates takes a long time to download and, after completed and restarting the virtual machines, I decided to perform a speed test that indicates the very slow network performance. But the performance is slower on one NETWORK card to another. Reduce the ports available to virtual machines on a single NETWORK card, that's what I got.
Using Speedtest.net as a gauge running on a dedicated XP Guest:
The Broadcom and Intel befriended 5Mbps showed and sometimes 10 Mbps.
Only Broadcom showed between 13-18Mbps from one trial to another.
Intel showed only 4-5 Mbps. never more than 5 Mbps!
Physical work stations connected to the same switch showed 45Mbps repeatedly!
All ports were originally configured as auto negotiate. I tried locking time ESXi and the Cisco switch to 1 GB Full duplex with no significant difference in the overall performance.
Has anyone seen this? Have you found a solution?

I got a similar promblem - found that the VM - NIC has been set at the 'flexible' type and VM-Ware tools were not properly installed.

As I was not able to install (linux, no gcc), I've removed the NETWORK card and put in again as an adapter 'e1000 '. From here, I had transferrates as expected ;-)

I hope this helps...

The DIMINFO affects query performance?
Hi all

A USER_SDO_GEOM_METADATA can. DIMINFO well defined to improve the query performance?

For all the tables in my system, I have the USER_SDO_GEOM_METADATA view like this:
DIMINFO
X; -2147483648; 2147483648; 5TH-5
Y; -2147483648; 2147483648; 5TH-5
Z; -2147483648; 2147483648; 5TH-5

Thanks to you all
The simple answer is Yes - it provides an alternative and faster I/O path.

The real question is whether it is supposed that was the data model and its use.

So your question is similar to asking if a varchar2 column indexing is good or not. The answer is "+ depends on +".

SQL query performance
I have a table that lists the users visits to pages on our website. The information takes the type of structure within our next record table:

VisitID | IDVisiteur | VisitPage | VisitDate
Index | UniqueID. VisitPage | Date/time

I need to get to IDVisiteur who visited in a user defined date range for a report that is to be written, and then get a count the days of separate visit that each user has visited our website. I have a request of work attached that will get me the result set, I want, but it's so _very_ slowly. Query Analyzer it shows that 84% included in table scans. I hope someone has a suggestion on how to optimize it. I am currently working on a MSSQL 8.0 Server, so I have no access to the function of tronque() that I would prefer to use on the dates, but that's a minor inconvenience.

Thank you

You have an index on visitdate?

Visitdate contains real-time, or are all the parts of the time 0:00? If they are all from 00:00, you don't need the convert function. Otherwise, you might have better luck by selecting all data from your database and using Q of Q for the counties.

Dan there on this one. Looking at the design table index was absent. Once I added an index my query performance dramatically, improved enough so that I don't have a lot of worries more. Thanks for the suggestion.

Question about the construction of cube / query performance (11.2.0.3)
Hi, I have a stupid question on the performance of cube generation. By choosing the precalc %, is linear (or nearly linear) construction time to that? for example if you select 10% going to be 3 times faster than the selection of 30%? Also, is it fair to assume that if only 10% of the values are precalculated, an average end-user queries have to hit 3 times more data and therefore be about 3 times slower?

Sorry, this on a virtual computer on your laptop, so test different configs build takes forever (I still have a load of cube really complete). Guess I should not be trying a cube Sun 15 on a virtual computer on your laptop, but trying to sell a DBA on the fact that she could improve the performance of our mini - DW.

Thank you
Scott
Aggregation based on costs (aka "Pre-computes percent") was introduced in 11.1 as a simpler alternative based on the level of aggregation. Product management dream was a linear parameter, but the complexity is quickly apparent. Which could measure the linearity against? The generation time? Time of the query? Total size of the disk? The result the balances of all of these factors, but is linear against any of them. Fortunately, behavior level percentage precompute was fairly consistent between cubes and patterns in our experience, so I can give you a rough characterization. But keep in mind that this is a guide only - you have to experience on your own scheme and a system to see what works for you. In particular, you must balance your own requirements on construction time, time of the request and the disk size.

* 0% *-this means no precomputation at all, so all data access will be dynamic. This is the recommended setting for the top of the page partition of a cube. If, for any reason, you want to use for the scores of leaves as well, then I advise you pass a cube uncompressed.

* 1% *-he pre-computes the smallest part of the cube that is allowed by the algorithm and would take certainly greater than 1% of the time taken by an accumulation of 100%. For partitions of leaves, it is usually best to increase the amount because you'll get much better query response time for not much more profitable in terms of disc size and the generation time. It may be a good level for the top of the page partition of a cube, but should be used with caution because the top of the page scores are often too big to pre-computes.

* 2%-19% *-these levels does not seem to be a lot of benefits since the amount of time and the total size of the disk is almost identical to a construction of 20%, but queries are slower.

* 20%-50% *-this range is probably the best compromise in terms of construction compared to the time of the query. The default value of the AWM is 35%, which is a good starting point. Lower it to 20% if you want a faster version and get up to 50% if you want to replace the faster queries. The setting is close to linear in this interval than outside it.

* 51%-99% *-you should probably avoid these levels, although I've seen 60% used in practice. The reason is that while the size of the cube and the length of the construction increase rapidly, the queries do not receive proportionally faster. Indeed, you may find that queries are slower because the code spends more time swapping in the pages of the disc.

* 100% *-this will be pre-computes all (non-NULL) cells in the cube. It may be a surprise after my advice about 51%-99%, but 100% is a reasonable level to choose. This is because the code is much simpler when you know that everything is precalculated and then stored in the disk pages.

Developer SQL vs TOAD - query performance issue
Someone pointed out the same queries are run slower in SQL Developer and TOAD. I'm curious on this issue, since I understand Java is 'slow', but I can't find another thread on this point. I do not use TOAD, so I can't compare...

Can it be linked to the amount of data returned by the query? What could be the other reasons for the SQL Dev works more slowly with a similar query?

Thank you
Attila
It occurs to me also that TOAD always uses the equivalent of the 'thick' JDBC driver Developer SQL can use 'thin' driver or the 'thick' driver, but the connections are usually configured with the pilot "thin", since you need an Oracle client to use the 'thick' driver

The difference is that the 'thin' drivers are written entirely in Java, but 'thick' drivers are written with only a small Java that calls the native executable (that's why you need an Oracle client) to do most of the work. In theory, a thick driver is faster because the code of the object should not be interpreted by the JAVA virtual machine. However, I heard that the performance difference is not that big. The only way to know for sure is to set up a connection with SQL Developer to use thick driver and see if it is faster (I would use a stopwatch).

Correct me if I'm wrong, but I think that if you use 'TNS' as your type of connection, Developer SQL use thick driver, while someone is using the default value, the type of ' basic' connection the thin driver. Otherwise, you need to use the connection type 'Advanced' and type in the JDBC URL custom for the thick driver.

ADFBC-ADF Faces: slow query filter
Hi community, I have a VO maped with a larger table, this VO is filter with setwhereclause, query works fine but it is too slow in all consultations.

I'm really confused tried everything but the request is still very slow.

Thanks Comunity.
Hi Peter, I have a solution to your problem, when you perform a filter with a method in the ViewObject implementation with this.setWhereClause (); Positional JDBC and consultation is built as follows:

SELECT * FROM (ORIGIN REQUEST VO) WHERE (YOUR CUSTOM FILTER)

This type of filter produces a query of doble reprocessing, in tables with many registers reduces the performance and speed of the query.

Try to use filters with viewCriterias, check your Oracle named binding style and use filter like that in your VO implementation:

//----

ViewCriteria vc = this.createViewCriteria ();
Vcr1 ViewCriteriaRow = vc.createViewCriteriaRow ();
VCR1.SetAttribute ("COD", "MyValue");
VC. Add (VCR1);
this.applyViewCriteria (vc);
this.executeQuery ();

//----

Satellite Pro A10 - SP2 or 3 slows the performance of XP?

Hello

I have a Satellite Pro A10 PSA15E that, over the years, had become very slow.

Recently, I upgraded it's RAM from 256 to the maximum of 1 GB to try to speed things up, but it did not help.

Then I reformatted the hard drive and reloaded the system using the Toshiba recovery disks. It worked well and the system performance has been excellent. However, with online safety in mind, I loaded the Windows SP2 (to go then to SP3) and it took the system back to where I started - very, very slow, in fact pretty much unusable.

Does anyone know if Toshiba compatible SP2 and SP3 on this laptop model?

If yes how install them without killing performance?

Thanks in advance.

Hello!

According to me, SP2 or SP3 is supported on this Toshiba laptop because two Service Packs are contains important security updates and I think that's not the problem.

If you install SP2 or SP3 you also get the center of security and better Windows Firewall. Maybe you should disable these two services given that the slowdown in the performance of the system (I always disable the two services).
Just go to start-run-services.msc online online and disable both services and set the startup type to disabled.

Good bye

Portege M400-146 slow startup performance

My 400 is significantly slow starts, compared to a lower specification laptop that this device was intended to replace. In addition to the understanding of the product, I see that there are more than 90 processes that run on this laptop more almost two times more than my previous unit and a lot more than my Small Business server that runs Win2k3/Exchange/ISA. My question is are there problems by removing the plethora of background tools that are of little use to me, specifically RAID/configfree

In addition there of the best-known problems associated slow performance/hang up with IE? There is an article that should resolve the issues of States with both software and an upgrade, but he didn't, even the last published this month made no difference.

In general, this unit is much slower than my previous spec'd base, grateful suggestions

Hello

I agree with you. Many processes of background can slow performance of the laptop.
But it is a simple fact. Each application or function on the laptop needs a clean process.
Portoge M400 is a portable high-tech and you can not compare with a low price laptops or office that support only a common features.

The Portege M400 supports the RAID Utility, HDD Protection, Tablet PC button, utility zooming, Rotation, ConfigFree, controls, utility of fingerprints and so on and the rest.

Of course, you can just disable or remove other feature requests, but then I wonder why you use the Portege M400 with the features and tools together?

But you can try to upgrade the memory. To my knowledge the Portege M400 supports 4 GB memory max. The upgrade improves performance.

Slow system performance

Hello

My brand new laptop of Hp-pavilion p001tx is 5 days that only, its execution is slow compared to the configuration system. My first use, it takes time for any task.

So, kindly help me to improve the performance of my system. I'll be very grateful to you if your suggestion works me.

Thank you.

Hello @MohdOmer,

Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the Forums of HP, I would like to draw your attention to the Guide of the Forums HP first time here? Learn how to publish and more.

I read your post on how your laptop behaves slowly with any application, and I'd be happy to help!

To increase the speed and performance of your operating system, I recommend later in this document on the system performance slow resolution (Windows 8). This should help with speed your applications run.

Please re-post with the results of your troubleshooting, and I look forward to your response!

Concerning

improve slow system performance

On the right hand corner, a message appears saying my CPU is at 100%, my computer very slow. How can I fix it?

If you have a setting in the bios. For the cpu cache, L1 or L2 cache, > settings > writeback, writethru.

Choose the writeback and see if that helps, don't know if it'll work or not, but it may be useful...

Looks like just a problem that I had where the computer seemed a little slow performance and could not find a reason any for her.

or

If it's showing the C drive is full remove unwanted files & Internet issues! This will help you

or remove the unwanted program by pressing CTRL + ALT + DELETE, end the process of unwanted programs. Try this also.

Kind regards

Chauvet J.
