Association rules - memory issue

Hi everyone,
I'm testing oracle data mining to generate a high number of association rules, starting from a table containing around 100 columns and 1800 lines. I transformed the table in a view as shown with the market basket demo, but I'm still having a memory error each time I'm trying to launch the data mining process.
I've tried with a table containing less columns and lines, and it worked fine.
Is there a way to set ODM to allow it to process this big table and generate millions of association rules without having some memory errors ?
Is it possible to find how exactly the apriori algorithm works, I mean to find if the sql process is only working with the RAM and writes in the database in the end, or if it commits into the database during the process (before exploding memory).
Merry christmas by the way !!!!!

Hi,
thanks again for your reply. I tried the tweak with the shared_pool_size, and I'm still having some memory issues.
Do you know how the model is build, and how it works technically ?
I can see that itemsets and rules are created when you build the model. Is it stored in a procedure (which applies the apriori algorithm), computes the model and then stores the rules generated into the database during commit ?
In this case all the process (model building) is stored in RAM, am I right ?
And that's why the process crash when there are too much data processed. Is it possible to avoid this, I mean commit the rules even during the process to free some RAM space in order to continue the rule generation ?

Association Rules problem

Hello,
I have a problem with making association rules in Oracle 10g ODM. The problem is as follows:
I have my test dataset for testing assoc. rules. I used that dataset before for testing assoc. rules models with Oracle 9i ODM release (9.2.0.4). And I have found significant number of rules within that dataset when I used Oracle 9i ODM (9.2.0.4.).
But when I use Oracle 10g ODM to build an association rules model with the same set of parameters (min. support, min. confidence and max. rule length) I've got 0 rules.
I can't find where is the problem, so I think that there is some sort of bug within Oracle 10g ODM.
Does anyone have similar experience or have some explanation for this?
Thnx in advance,
Ivan

What version of Data Miner are you using?
If you are using the api directly, are you using the
java or pl/sql api.
Thanks, MarkI've been using Java API.
I've continued my investigation of the mentioned problem and I have found that DMS throws following exception:
ORA-38605: FI not enough memory (stringK) for candidate generation(stringK)
Cause: There was insufficient available memory for candidate generation.
Suggested action from Metalink is:
In workarea_size_policy='manual' mode, set ficarea_size to a reasonably larger value. Or, in workarea_size_policy='auto' mode, set pga_aggregate_target to a reasonably larger value
And I've increased the size of my SGA more than three times (from 128 to 512 MB), set work_area_policy=auto and set pga_aggregate_target to 20% of SGA .
After that I've got following exception:
ORA-40101: Data Mining System Error ODM_ASSOCIATION_MODEL-BUILD--20010
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 105
ORA-06512: at "DMSYS.ODM_ASSOCIATION_RULE_MODEL", line 150
ORA-06512: at "DMSYS.ODM_ASSOCIATION_RULE_MODEL", line 1299
ORA-01452: cannot CREATE UNIQUE INDEX; duplicate keys found
ORA-06512: at "DMSYS.ODM_ASSOCIATION_RULE_MODEL", line 1364
ORA-06512: at line 1
DMS throws this exception after longer time of task execution.
Now, I don't know what to do further.
I repeat that with the same dataset and same model parameters (support, confidence and max. rule length) I've got significant number of rules with ODMS within Oracle 9i database (9.2.0.4).
Thnx,
Ivo

Problems with Association Rules

This error is generated on the sample data as used in the ORACLE 10G Release 2 Data Mining Tutorial, and on other datasets that I tried.
My sense is that the algorithm is expecting data in the datatype of DM_NESTED_NUMERICALS, even though the documentation asks for transactional data. When I converted to nested columns, the prog errored out again as it was expecting a number rather than nested column.??

Hi Carolyn,
I reviewed the tutorial and tested out the example for Association Rules. The example uses SH.SALES and SH.PRODUCTS.
It worked fine.
ODMr converts the "transactional" data, in the case of Association Rules, into DM_NESTED_NUMERICALS.
When ODM documentation refers to transactional data, it implies the use of nested columns. This can be confusing given that older versions of ODM actually supported a "transactional format", which is now supported only through nested columns.
I copied the following view definition that was passed in to ODM to build the Association Rules model (based on the tutorial noted above). Take a look at them to get a better understanding on what ODMr is doing to prepare the data.
If you can give us a specific example including the tutorial table you used and the settings you specified in the Association Rules Wizard, I can review that to see what the problem might be.
Thanks, Mark

Report (uses LDB's) giving dump due to memory problem

Hi,
I have a report which is giving dump in production due to memory problem.
Memory is increased from basis part,but still getting same error.
the report uses Logical DataBases.
Can anyone suggest solution to solve this problem.
regards
Mallik

Hi Amit,
thanks for ur quick reply and ur idea "make changes in development and write the logic to read records in chunks".
I have n't worked on LDB's till now.So i Don't know how I can read the data in chunks from LDB's.
Can u Plz give some idea how to read data in chunks.
Iam also sending the code,if possible ,plz go thru it and give me some idea.
Hope u will help me.

Memory problems with PreparedStatements

Driver: 9.0.1 JDBC Thin
I am having memory problems using "PreparedStatement" via jdbc.
After profiling our application, we found that a large number oracle.jdbc.ttc7.TTCItem objects were being created, but not released, even though we were "closing" the ResultSets of a prepared statements.
Tracing through the application, it appears that most of these TTCItem objects are created when the statement is executed (not when prepared), therefore I would have assumed that they would be released when the ResultSet is close, but this does not seem to be the case.
We tend to have a large number of PreparedStatement objects in use (over 100, most with closed ResultSets) and find that our application is using huge amounts of memory when compared to using the same code, but closing the PreparedStatement at the same time as closing the ResultSet.
Has anyone else found similar problems? If so, does anyone have a work-around or know if this is something that Oracle is looking at fixing?
Thanks

From your mail, it is not very clear:
a) whether your session is an HTTPSession or an application defined
session.
b) What is meant by saying: JSP/Servlet is growing.
However, some pointers:
a) Are there any timeouts associated with session.
b) Try to profile your code to see what is causing the memory leak.
c) Are there references to stale data in your application code.

hi,
we have some memory - problems with the WebLogic Application Server
4.5.1 on Sun Solaris
In our Customer Projects we are working with EJB's. for each customer
transaction we create a session to the weblogic application server.
now there are some urgent problems with the java process on the server.
for each session there were allocated 200 - 500 kb memory, within a day
the JSP process on our server is growing for each session and don't
reallocate the reserved memory for the old session. as a work around we
now restart the server every night.
How can we solve this problem ?? Is it a problem with the operating
system or the application server or the EJB's ?? Do you have problems
like this before ?

Sound Problem Plus Memory Problem

I've also posted this same issue at the EVGA website with no help what so ever yet. Also if it's ok I'm having the above mentioned memory problem that it probable not related but if anyone does have good input I would love to hear. Hope this doesn't break any rules, didn't see anything in the listed rules thread. So here it goes.
Ok I'm having a few minor but very perplexing and annoying problems. I have recently built a new rig to include the following.
Windows 7 64 bit Home Edition
EVGA P55 FTW Intel P55 Socket LGA56
Intel Core i5-750 2.66Ghz 8M LGA56 CPU
Corsair Dominator 4GB DDR3 PC2800 (2 x 2 GB sticks)
Ultra LSP750 750w Power Supply
Seagate TB Serial ATA HD 7200/32MB
Cooler Master HAF 932 Full Tower Black Case
Galaxy GeForce GTS 250 52MB PCIe x2 (SLI Setup)
BFG - NVIDIA GeForce 9800 GT GB GDDR3 PCI Express Graphics Card (Physx Setup)
PROBLEM ONE:
This one I had a lot less that I was able to actually try because it just confused the crap out of me. So I started by going to test my sound. I'm running an optical cable from the on board sound port to back of my sony surround sound system. I get sound from my left and right channel but nothing from the center, rears or sub. So figure no biggie just need to change the configuration from 2 speaker stereo to 5. surround sound. Guess what... the option isn't there? WTF? A sound card with an optical port with no 5. support? So went online found the drivers for the sound on the mother board and tried reinstalling thinking maybe somthing was wrong with the drivers on the CD. Well it still didn't work. So I figured what ever, I got an external sound card that I know works with Windows 7 since it was on other desktop and hooked it up. Its a Creative - Sound Blaster X-Fi Surround 5. External USB Sound Card. Well it installs fine and I go to test it. Yep you guessed it! Still only sound from the left channel and the right channel with no option for surround sound. So I was able to find updated drivers for that and ran em. Well now I have an option for Surround sound with side speakers only no rear. Oh but it doesn't really matter because the left and right channel are still the only ones able to produce sound. And yes the speakers work I turned on my X-Box 360 hooked up to the same speakers and LCD tv and played COD4 with full sound working fine. So something else has to be happening I just have no idea.
PROBLEM TWO:
The second problem was with the memory. Everything booted fine but it initial only detected 2 GB. By the way I had them installed in slots and 3. So I shut down and popped em out checked the copper connectors everything looked fine and reseated the chi
ps.
This time during the boot up I checked the BIOS. It saw all 4 GBs of memory. Continued into Windows. Windows now saw all 4 but only .99 GB was available. Now the only other time I've seen anything like this was with on board video sharing the memory, and even then it wasn't half of the systems total memory. I then tried shutting down and putting the chips in 2 and 4 just see what would happen. Well I got an EA post error on the LED, couldn't even boot. So I figured o'well power down completely and tried to run the memory in 2 and 3 to run it out of dual channel. I was able to boot but still had the same issue. .99 GB available and still saw all 4. At this point it was just getting silly so I figured ok I'll download the new BIOS with my laptop, burned it to a CD. Booted the desktop and ran the BIOS flash. Update seemed work fine, honestly the BIOS didn't look much different and I didn't take note of the previous version before I did it so I can only assume it worked. However it did not fix my problem. So I'm still stuck at windows seeing 4 GB of memory with only .99 available.
Anyway... I'll keep trying to get this working and hunting around online, but I'm really hoping you all have some ideas. I'll be trying to call EVGA today for some help too and possibly Corsair. Thanks in advance for the help!

Hello,
cannot help with the sound problem.
For memory, I've got almost the same thing but with 4 sticks of 2gb and only 2 detected on an ASUS P7P55D deluxe.
Bios was my issue but I needed to do this (but with pairs of sticks instead of sticks) after the bios update to finally get my 8gb under windows:
Make a clear cmos. Then boot the computer with only one stick of ram in the port .
If everything is fine, turn off and add the other port of the same color for dual channel.
If it does not boot with the 2 sticks in the port of the good color, try to switch ports again. Maybe one stick is dead?

Association rule in SQL Server Data Mining

I have been working on a problem on association rules in SQL Server Data Tools (Visual Studio 2008) for quite a while but have not yet been able to figure out the solution.
The problem is: I have a table named Sales_history in my SQL database. This table has following columns: CustomerID, ItemID, Month (from May2012 to April 2013), QtyShipped. I am looking to find association between Items and i want to provide recommendation
to the Customer (In this case CustomerID) based on their purchases.
Note: there are around 630 customers and about 34000 products in my table.
My approach:
I marked History_Table as both Key and nested. And in the Key, i checked CustomerID as input and Key whereas in nested, i checked ItemId as Key, input and Predict.
When i run the model, i get a solution but i am not sure if i am configuring it right. Also i am not sure how i can write prediction join query to generate Item recommendations . I am really struggling with
this problem, eagerly waiting for the reply. Thank you.

Hi Tatyana,
Thank you so much for your reply. I have now been able to create the data mining model using association rule and by writing a DMX query, i am able to generate the item recommendations to be given to customers for items they have purchased. However, i have
noticed one thing that in the DMX query, it gives the same item recommendation for any item i put inside the query.
Also, if i put any item in the DMX query from the generated list of recommended items, the output of that query also shows the item that is inputted inside the query.
Here is the query, that i am writing to generate item recommendations
SELECT predictassociation (CrossSellingModelV3.[Ztb Customer Item v3],INCLUDE_STATISTICS,5)
FROM CrossSellingModelV3
NATURAL PREDICTION JOIN
(SELECT
(SELECT '17IS56126' as m )
AS Ms)
AS t
What can be the possible reason behind this? Is this something related to the kind of data i have? In my data, there are 632 distinct customers and 34000 distinct products.
If i execute this query in management studio.
select customer_CD, COUNT(Item_CD) from ztb_Sales_History
group by customer_CD
order by 2 desc
the output shows that there are some customers who have bought just 1 item and also there are customers who have bought 2400 items. i mean the range is very high.

Memory Problem Bridge CS4 under Win7

Hi!
I am running Bridge CS 4 on a brand new multimedia laptop (best ati graphic card, 4 gb ram, hundrets of gb free space) and one and the same bridge that ran well on my old xp laptop is starting to tremble of memory problems and pops up in German "is running out of memory, a restart is recommended". The cache preferences are all ok I think. Where else could I have a look at in order to delete this bug ?!
Thanks, Sebastian

Memory can also mean inadequate page file, memory problems, or cache. Also, since it is a new computer don't rule out defective RAM.

Association Rule Model Fails to Build

Hi all
I am running the association rules model (java api) and sometimes when I use attributes from lower hierarchies the model fails to complete and runs for
ever. In addition when I stop the process from netbeans the hard disk indicator remains permenantly on and my computer is really slow and I am unable to access anything. My attributes are quite long strings (include also gaps). Do you think that affects the model?
Thank u
K

Based on the number of rows and transactions, you are averaging 23.5 items per transaction. With only 80+ items and a few value combinations for each, my guess is that the baskets are quite dense. Many of the transactions will contain a decent-sized portion of the item name-value combinations.
Association rules has a parameter to limit the length of the rules that are generated. Have you set this to try limiting to shorter rules? Have you tried a maximum of length 2 to see if it completes? My guess is that the density of the data leads to exponentially larger combinations of rules as the length of the rule increases, and this requires more memory.
Please try to constrain the rule length to experiment. Once you have short rules (single antecedent item), take a look and see how many rules and itemsets are generated at your provided support and confidence levels (support will constrain itemsets, and support plus confidence will constrain rules). Try to increase the maximum rule length by one more, and see how fast the count of rules and itemsets expand.
This should help understand more about your data and the correct choice of algorithm parameters.

Association Rules - dmardemo.java - DisplayAssociationRules method

Hi, friends!
I'm making some changes in the sample Java demo for the Association Rules - dmardemo.java. I've created another method which contains the name of the model just created before and in this same method, I call the method to display the association rules detected:
public static void restoreRules(String modelNome) throws JDMException {
m_modelName = modelNome;
model = (AssociationModel)m_dmeConn.retrieveObject(
m_modelName, NamedObject.model);
displayAssociationRules(model);
In another class, which is a GUI, I'm trying to call that method to restore all the rules found in the mining process and display them in a jTable Swing component. For this, I've tried to adapt the main method (displayAssocationRules) to do this, as follows:
public static Object displayAssociationRules(AssociationModel model)
throws JDMException {
// DISPLAY TOP-10 ASSOCIATION RULES
Object[] obj = new Object[5];
int contador = 0;
// 1. Set order by confidence DESC, support DESC
OraRulesFilter filter = (OraRulesFilter) m_filterFactory.create();
filter.setOrderingCondition(
new RuleProperty[] { RuleProperty.confidence, RuleProperty.support},
new SortOrder[] { SortOrder.descending, SortOrder.descending }
// 2. Set to return the first 10 rules only
filter.setMaxNumberOfRules(10);
// 3. Retrieve rules
Collection rules = model.getRules(filter);
Iterator iRules = rules.iterator();
while( iRules.hasNext() )
OraAssociationRule rule = (OraAssociationRule) iRules.next();
obj[0] = rule.getRuleIdentifier();
//System.out.print( "Rule " + rule.getRuleIdentifier() + ": " );
Itemset antecedent = rule.getAntecedent();
//obj[1] = antecedent.getItems();
Object[] ante_items = antecedent.getItems();
// sort the items in antecedent to produce deterministic order of items
TreeSet sortedSet = new TreeSet();
for(int i = 0; i < obj.length; i++)
sortedSet.add(ante_items);
obj[1] = ante_items;
Iterator sortedI = sortedSet.iterator();
/*while(sortedI.hasNext())
System.out.print(sortedI.next() + " ");*/
Itemset consequent = rule.getConsequent();
Object[] cons_items = consequent.getItems();
obj[2] = cons_items;
obj[3] = m_df.format(rule.getSupport());
obj[4] = m_df.format(rule.getConfidence());
/*System.out.println("==> " + cons_items[0] + " (support=" +
m_df.format(rule.getSupport()) + ", confidence=" + m_df.format(rule.getConfidence()) + ")" );*/
return obj;
Some parts of the old code are present in that for you to compare what I've done. However, it's not working. What should I do to see the rules generated in the process in a jTable?
Regards
Luis

As you can see in the code above, I've split the code into two parts. However, a problem is happening when I try to restore the rules to the GUI.
"Exception in thread "AWT-EventQueue-0" javax.datamining.JDMIllegalArgumentException: The required argument objectName is null. Supply a non-null value."
It says that I'm not passing any parameters to the method. But, as you can see, in the first method I've created, I took the name of the model and transfers it for the method displayAssociationRules as a AssociationModel objet.
In the GUI, in an event for the button "Restore Rules", I've put this code below:
String modelo = Principal.getModelName(); // where Principal is the main GUI class for the execution of the process.
dmardemo.restoreRules(modelo);// I call the method in the dmardemo class to restore the rules having a String (modelo) as its parameter. That's when the problem happens. Is the argument really null, as the error message says?
Regards
Luis

And your version of Oracle is?
If 10g look into using Transparent Data Encryption (TDE). You can find docs on it at http://tahiti.oracle.com.

N96 Memory problem (internal 16GB)

N96 Memory problem (internal 16GB)
If I fill the internal memory with more than approx 5gb the phone goes crazy...
(9,3Gb free)
Here are a couple of examples
* The phone becomes alot slower
* When powering up the phone stops at a white blank screen until * I press the power button again.
* When starting the music player all buttons associated with the music player(both on phone and handsfree) becomes unresponsive and the only way to stop the music is to remove the battery to turn off the phone.
Another problem that occasionally occurs even if I have more free space on my memory card is:
* When using the alarm clock there is a 33% chance that the phone will freeze when I turn it off. The only way to use the phone again is to remove the battery.
I haven't updated the phone yet because the update isn't available yet in sweden it seems.
Solved!

This may be the issue, New content!:
Scanning for new content (slowness in UI)
- This is somewhat improved in 11.018 but still:
- If you've loaded many Pictures, Videos or Music, you may see the device appear to slow down or even become unresponsive. After new content has been added, it is being scanned by the device and being added to the media applications. Until that happens, the new content may not be visible in these applications (e.g. Photos and Video Center application) right away. The phone will need to find the files and create the thumbnails and other details. This information creation takes time and the processing may slow down the device. Your best option is to open Video Center and Photos and leave open in the background then check after a few minutes if the videos and pictures you loaded are already there before using your device.
The same applies if you insert a memory card with lots of content on it.
- Do Not leave the Photos or video center in background during this time.

Memory Problem with SEt and GET parameter

hi,
I m doing exits. I have one exit for importing and another one for changing parameter.
SET PARAMETER exit code is ....
*data:v_nba like eban-bsart,
       v_nbc like eban-bsart,
       v_nbo like eban-bsart.
       v_nbc = 'CAPX'.
       v_nbo = 'OPEX'.
       v_nba = 'OVH'.
if im_data_new-werks is initial.
if im_data_new-knttp is initial.
    if im_data_new-bsart = 'NBC' or im_data_new-bsart = 'SERC' or im_data_new-bsart = 'SERI'
       or im_data_new-bsart = 'SER' or im_data_new-bsart = 'SERM' or im_data_new-bsart = 'NBI'.
      set parameter id 'ZC1' field v_nbc.
    elseif im_data_new-bsart = 'NBO' or im_data_new-bsart = 'NBM' or im_data_new-bsart = 'SERO'.
      set parameter id 'ZC2' field v_nbo.
    elseif im_data_new-bsart = 'NBA' or im_data_new-bsart = 'SERA'.
      set parameter id 'ZC3' field v_nba.
    endif.
endif.
endif. *
and GET PARAMETER CODE IS....
get parameter id 'ZC1' field c_fmderive-fund.
get parameter id 'ZC2' field c_fmderive-fund.
get parameter id 'ZC3' field c_fmderive-fund.
FREE MEMORY ID 'ZC1'.
FREE MEMORY ID 'ZC2'.
   FREE MEMORY ID 'ZC3'.
In this code i m facing memory problem.
It is not refreshing the memory every time.
So plz give me proper solution.
Its urgent.
Thanks
Ranveer

Hi,
   I suppose you are trying to store some particular value in memory in one program and then retieve it in another.
If so try using EXPORT data TO MEMORY ID 'ZC1'. and IMPORT data FROM MEMORY ID 'ZC1'.
To use SET PARAMETER/GET PARAMETER the specified parameter name should be in table TPARA. Which I don't think is there in your case.
Sample Code :
Data declarations for the function codes to be transferred
DATA : v_first TYPE syucomm,
       v_second TYPE syucomm.
CONSTANTS : c_memid TYPE char10 VALUE 'ZCCBPR1'.
Move the function codes to the program varaibles
v_first = gv_bdt_fcode.
v_second = sy-ucomm.
Export the function codes to Memory ID
EXPORT v_first
       v_second TO MEMORY ID c_memid.        "ZCCBPR1 --- Here you are sending the values to memory
Then retrieve it.
Retrieve the function codes from the Memory ID
IMPORT v_first TO v_fcode_1
         v_second TO v_fcode_2
FROM MEMORY ID c_memid.                                   "ZCCBPR1
FREE MEMORY ID c_memid.                                   "ZCCBPR1
After reading the values from memory ID free them your problem should be solved.
Thanks
