Need Help with INSERTS & INDEXES

Let me try explaining my scenario and then my confusion:
Scenario:
Parent_table
Child_table
Both Parent_table & Child_table have Indexes and Constraints.
Confusion:
If I remove all Indexes and Constraints, my INSERTS are 10 times faster. Howevere I am taking a chance of:
1. Loosing Referential Integrity (No Parent row for a Child Row).
2. Storing Duplicate data.
The chnaces of either one of this happening is rare, but it is a definite possiblility.
I am trying to find some articles that will give me some guidance on how this should be done right. Such that I can disable certain Indexes, so that the existing data can be queried without any problems and the new data is Indexed after the load.
Any help will be appreciated.
-- Thanks

Maintaining indexes certainly requires some additional overhead during inserts. Generally, though, you've got indexes in place to allow you to query data at an acceptable speed. Presumably, when you remove all your indexes, all your reporting/ OLTP applications will crawl to a halt.
What are the indexes you have on these tables and why do those indexes exist? Frequently, you'll find that you may have indexes that are useless either because they are essentially duplicated by other indexes or because they are indexing attributes that don't benefit from having indexes. If 90% of your insert time is being spent updating indexes, that certainly seems like a possibility here...

Need Help with Inserting Timeline Markers

Friends,
I have not use my premiere element 3.2 since 2008 and forgot some of the procedures. now, I need help with the insertion of Timeline Markers. I did what the Help Page showed me. But the markers were not effective in the resulting DVD, or, even when viewing the video in the editing page as if thye were not there! Here is what I did:.
1) Click the Timeline button.
2) Click in an empty space in a video or audio track in the Timeline to make the Timeline active and deselect any clips.
3) Move the current-time indicator in the Timeline to the frame where I need the marker.
4) Click the Add Marker icon in the Timeline to place the Marker 5 times where I want them.
5) Verified that each Timeline Marker is present at the intended place.
6) Burned DVD
7) Can NOT jump to any of the intended Marker in the Resulting DVD during playback.
The question is "What did I do wrong or didn't do?" It seems that I did the same before and worked! Please advise!
Also, what are the significance of the Red line just below the Timeline and the yellow bars inside the video and audio frames. But after preforming Timeline/Render Work Area, they were all gone? What purposes do they serve and what is the significance of Rendering? Thank you for your help!
I repeat the process and did a Rendering before making the DVD also. It did not help!

Steve,
Long time no talk! You used to help me out many times when the PE-1 through PE-3 came out. I was HOPING you would still be around and you are! You came through again this time! Many thanks to you.
I use the Add DVD Scene button to insert the Markers. They are Green. Made a DVD and the markers work OK although ythey are "effective" during play back using the editing window.
While that problem was solved, will you come back and answer the other two questions concerning Rendering and the Red/Yellow lines? I would appreciate it very much!

Need Help with inserting a screen shot

Can someone pleassse help me?! If any of you are familiar with popular youtubers and how in their videos they include screen shots of facebook or twitter questions and they have them so they roll across the bottom of the screen, can you please help me! If anyone knows how to do this in Imovie 11 it would be HUGELY appreciated! Because when i try the picture in picture settings it zooms the screen shot so its massive and its also not an oblong shape anymore (like the shape of a facebook reply) i also need help at how this would transition to roll in from one side of the screen to the other?!
PLEASE HELP ME!!

I think it is possible to do this in iMovie, although perhaps easier in Final Cut Pro X, which I would guess that iJustine is using.
First, I would take a still image of my video at the points where I want to superimpose a graphic. Since she is mostly superimposing graphics on her talking head, a single still might be sufficient.
For getting a still out of iMovie, see my User Tip here.
https://discussions.apple.com/docs/DOC-3231
Now, you will want to take this still to a photo editor that allows you to edit layers. Use PhotoShop if you have it. If you do not already have PhotoShop, it can be rather expensive, so I would suggest a tool like Acorn or Pixelmator, which I think are available in the Mac App Store.
Create a project in the dimensions of your iMovie still, e.g. 1920x1080.
You would put the still on the bottom layer, so you know where to put yoru graphics. You would position the graphic or screen grab at the next layer up. Now I would export the upper layer only as a PNG file. The PNG file has an Alpha Channel, which means you will see only the graphic and not the still in the background.
The main thing Final Cut Pro would give you would be the easy ability to have multiple graphics on the screen at the same time.
Now you can drag this PNG file into iMovie and drop it on the project clip where you want it to appear. A popup menu will appear. Choose Cutaway.
There are probably other ways to do this, but that is the way I would do it.

Need help with inserting frame with scrolling images

Hi,
Im a beginner and need help putting a single box/frame with scrolling images in the middle of my layout, so that when viewed in browser, the header and footer remain in place, while the images and info in the frame in the centre of the page can be scrolled down/up?

You can use an iframe element <iframe src="" width="" height="" scrolling="yes"> though if you're concerned with crawlers you should avoid frames as much as possible.

Need help with inserting 10MB CLOB

Hi,
I have an urgent issue and desperately need some help.
There are several files on a FTP server that I need to insert their contents into a CLOB type column. One of the files has more than 10MB contents. What I've been doing is after connection is made to the FTP server, read in the contents in a file line by line into a String, then execute a SQL INSERT statement to insert a new record into the target table.
+//.... make connection, read in files and parse into a String variable called fileContents+
String psInsert = "Insert into FileTrack (Name, Contents) values";
PreparedStatment ps = conn.prepareStatement(psInsert "(?,?)");+
ps.setString(1, "some name");
ps.setObject(2, fileContents);
ps.executeUpdate();
The above works fine for all other smaller files, except the 10MB one. The error I got was SQLCODE: -302, SQLSTATE: 22001, which is about not enough space issue. So I increased the CLOB column size and made sure it doesn't exceed the initial CLOB size setting and the database has plenty of space for storing this 10MB file. Still, I got the same error.
Then I tried the following:
ps.setObject(2, fileContents, java.sql.Types.CLOB);
Failed with same error...
Then I tried this:
FileInputStream inputStream = new FileInputStream(fileContents);
ps.setAsciiStream(2, inputStream, (int)()fileContents.length()));
Still failed with the same error....
Then I changed to ps.setCharStream()... still failed....
What other options do I have to insert the 10MB contents? Can someone please help?
Thanks heaps in advance!!

we're still trying to upload that CLOB. Takes a while over this 2400bps modem ;)

Seeing Database Changes Made Internally and Externally
This section discusses the ability of a result set to see the following:
its own changes (DELETE, UPDATE, or INSERT operations within the result set), referred to as internal changes
changes made from elsewhere (either from your own transaction outside the result set, or from other committed transactions), referred to as external changes
Near the end of the section is a summary table.
Note:
External changes are referred to as "other's changes" in the Sun Microsystems JDBC 2.0 specification.
Seeing Internal Changes
The ability of an updatable result set to see its own changes depends on both the result set type and the kind of change (UPDATE, DELETE, or INSERT). This is discussed at various points throughout the "Updating Result Sets" section beginning on , and is summarized as follows:
Internal DELETE operations are visible for scrollable result sets (scroll-sensitive or scroll-insensitive), but are not visible for forward-only result sets.
After you delete a row in a scrollable result set, the preceding row becomes the new current row, and subsequent row numbers are updated accordingly.
Internal UPDATE operations are always visible, regardless of the result set type (forward-only, scroll-sensitive, or scroll-insensitive).
Internal INSERT operations are never visible, regardless of the result set type (neither forward-only, scroll-sensitive, nor scroll-insensitive).
An internal change being "visible" essentially means that a subsequent getXXX() call will see the data changed by a preceding updateXXX() call on the same data item.
JDBC 2.0 DatabaseMetaData objects include the following methods to verify this. Each takes a result set type as input (ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_SENSITIVE, or ResultSet.TYPE_SCROLL_INSENSITIVE).
boolean ownDeletesAreVisible(int) throws SQLException
boolean ownUpdatesAreVisible(int) throws SQLException
boolean ownInsertsAreVisible(int) throws SQLException
Note:
When you make an internal change that causes a trigger to execute, the trigger changes are effectively external changes. However, if the trigger affects data in the row you are updating, you will see those changes for any scrollable/updatable result set, because an implicit row refetch occurs after the update.
Seeing External Changes
Only a scroll-sensitive result set can see external changes to the underlying database, and it can only see the changes from external UPDATE operations. Changes from external DELETE or INSERT operations are never visible.
Note:
Any discussion of seeing changes from outside the enclosing transaction presumes the transaction itself has an isolation level setting that allows the changes to be visible.
For implementation details of scroll-sensitive result sets, including exactly how and how soon external updates become visible, see "Oracle Implementation of Scroll-Sensitive Result Sets".
JDBC 2.0 DatabaseMetaData objects include the following methods to verify this. Each takes a result set type as input (ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_SENSITIVE, or ResultSet.TYPE_SCROLL_INSENSITIVE).
boolean othersDeletesAreVisible(int) throws SQLException
boolean othersUpdatesAreVisible(int) throws SQLException
boolean othersInsertsAreVisible(int) throws SQLException
Note:
Explicit use of the refreshRow() method, described in "Refetching Rows", is distinct from this discussion of visibility. For example, even though external updates are "invisible" to a scroll-insensitive result set, you can explicitly refetch rows in a scroll-insensitive/updatable result set and retrieve external changes that have been made. "Visibility" refers only to the fact that the scroll-insensitive/updatable result set would not see such changes automatically and implicitly.
Visibility versus Detection of External Changes
Regarding changes made to the underlying database by external sources, there are two similar but distinct concepts with respect to visibility of the changes from your local result set:
visibility of changes
detection of changes
A change being "visible" means that when you look at a row in the result set, you can see new data values from changes made by external sources to the corresponding row in the database.
A change being "detected", however, means that the result set is aware that this is a new value since the result set was first populated.
With Oracle8i release 8.1.6 and higher, even when an Oracle result set sees new data (as with an external UPDATE in a scroll-sensitive result set), it has no awareness that this data has changed since the result set was populated. Such changes are not "detected".
JDBC 2.0 DatabaseMetaData objects include the following methods to verify this. Each takes a result set type as input (ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_SENSITIVE, or ResultSet.TYPE_SCROLL_INSENSITIVE).
boolean deletesAreDetected(int) throws SQLException
boolean updatesAreDetected(int) throws SQLException
boolean insertsAreDetected(int) throws SQLException
It follows, then, that result set methods specified by JDBC 2.0 to detect changes--rowDeleted(), rowUpdated(), and rowInserted()--will always return false with the 8.1.6 Oracle JDBC drivers. There is no use in calling them.
Summary of Visibility of Internal and External Changes
Table 12-1 summarizes the discussion in the preceding sections regarding whether a result set object in the Oracle JDBC implementation can see changes made internally through the result set itself, and changes made externally to the underlying database from elsewhere in your transaction or from other committed transactions.
Table 12-1 Visibility of Internal and External Changes for Oracle JDBC

For implementation details of scroll-sensitive result sets, including exactly how and how soon external updates become visible, see "Oracle Implementation of Scroll-Sensitive Result Sets".
Notes:
Remember that explicit use of the refreshRow() method, described in "Refetching Rows", is distinct from the concept of "visibility" of external changes. This is discussed in "Seeing External Changes".
Remember that even when external changes are "visible", as with UPDATE operations underlying a scroll-sensitive result set, they are not "detected". The result set rowDeleted(), rowUpdated(), and rowInserted() methods always return false. This is further discussed in "Visibility versus Detection of External Changes".
Oracle Implementation of Scroll-Sensitive Result Sets
The Oracle implementation of scroll-sensitive result sets involves the concept of a window, with a window size that is based on the fetch size. The window size affects how often rows are updated in the result set.
Once you establish a current row by moving to a specified row (as described in "Positioning in a Scrollable Result Set"), the window consists of the N rows in the result set starting with that row, where N is the fetch size being used by the result set (see "Fetch Size"). Note that there is no current row, and therefore no window, when a result set is first created. The default position is before the first row, which is not a valid current row.
As you move from row to row, the window remains unchanged as long as the current row stays within that window. However, once you move to a new current row outside the window, you redefine the window to be the N rows starting with the new current row.
Whenever the window is redefined, the N rows in the database corresponding to the rows in the new window are automatically refetched through an implicit call to the refreshRow() method (described in "Refetching Rows"), thereby updating the data throughout the new window.
So external updates are not instantaneously visible in a scroll-sensitive result set; they are only visible after the automatic refetches just described.
For a sample application that demonstrates the functionality of a scroll-sensitive result set, see "Scroll-Sensitive Result Set--ResultSet5.java".
Note:
Because this kind of refetching is not a highly efficient or optimized methodology, there are significant performance concerns. Consider carefully before using scroll-sensitive result sets as currently implemented. There is also a significant tradeoff between sensitivity and performance. The most sensitive result set is one with a fetch size of 1, which would result in the new current row being refetched every time you move between rows. However, this would have a significant impact on the performance of your application.

Need help with inserting hyperlinks

I have created a slideshow presentation and the slides are
all under one presentation. They are only scrolling in the
presentation field. I have the presentation field separated by
Keyframes. I ahve 4 keyframes and they all have a picture attached
to them. This is how I am getting my scroll to work. It is not
working any other way. The only thing that I need to figure out now
is how to get the hyperlinks to work. The only way that I can get
it to go to the link, is by putting goto and the link but that is
not enabling me to click on the link, it is just opening it when
the page loads. I need to know how I can get the hyperlinks to work
when you click and not when you load. I am sure that this is a
script issue, but I am not sure what I am supposed to type in the
script to get it to work. I just need some guidance on this. Can
someone please let me know for one if I am on the right track and
if not please direct me there too. But most importantly, I need to
get the hyperlinks working.
Thanks,
Katie Kane

For the images to be clickable, they will have to either be
Buttons or MovieClips. If your images on the stage are Graphics
then to easily turn them into MovieClips, select one of them and
then press the F8 key. Make sure to select MovieClip in the radio
button list. Once you have turned it into a MovieClip you will have
to give it an Instance name (see the Properties dialoge box near
the buttom of the screen in Flash). You will use the Instance name
to reference this image (now a MovieClip) in ActionScript.
Assume that you have done the steps above and named your
movieclip myImage. Then to allow it to be clickable just place the
following action script on the key frame where the image is
located:
myImage.onRelease = function() {
getURL("
http://www.adobe.com", "_blank");
Then when you click on the image it will open a new browser
window and goto the web address provided.
Does this help more?

Need help with inserting element into a grid

Hi,
I'm trying to add an element in a 11x11 grid, but the program stop and give me 2 error (identified in the code) and I have no idea on what is wrong with those line. If anyone have any idea, suggestion or an other way to do this, I could use some help.
Thx

Need help with inserting rows in resultset

hello!
i want to insert a row in my result set and i want that my table shows this row promptly after i have inserted it in my result set...
but when i use following code for my resultset:
rs.moveToInsertRow();
rs.updateInt(1,nr);
rs.updateString(2, name);
rs.insertRow();
and call fireTableDataChanged afterwards -> nothing happens, rows are inserted in resultset but not shown in my table??
anyone a clue??

rs.moveToInsertRow(); // moves cursor to the insert row
rs.updateString(1, "AINSWORTH"); // updates the
// first column of the insert row to be AINSWORTH
rs.updateInt(2,35); // updates the second column to be 35
rs.updateBoolean(3, true); // updates the third row to true
rs.insertRow();
rs.moveToCurrentRow();
This is from the JAVA API. Something makes me think you might want to try doing the last method execution.
rs.moveToCurrentRow();

I need help with event structure. I am trying to feed the index of the array, the index can vary from 0 to 7. Based on the logic ouput of a comparison, the index buffer should increment ?

I need help with event structure.
I am trying to feed the index of the array, the index number can vary from 0 to 7.
Based on the logic ouput of a comparison, the index buffer should increment
or decrement every time the output of comparsion changes(event change). I guess I need to use event structure?
(My event code doesn't execute when there is an event at its input /comparator changes its boolean state.
Anyone coded on similar lines? Any ideas appreciated.
Thanks in advance!

You don't need an Event Structure, a simple State Machine would be more appropriate.
There are many examples of State Machines within this forum.

If needed more clarifications ask me.
Thank you,

if you got into the bios/uefi and have determined that the hdd is being detected then that is good. At least the hdd is operating to some extent, although still may be corrupt OS or the like.
Eagle asked you what OS your using (i.e., Windows 8.1 64-bit, Windows 7 32-bit, etc.). I see that English is not your native language so we'll just have to work with that as best we can.
Did you make any changes to the operating system (OS) as a result of the link you posted, and what were they?

Need help with Berkeley XML DB Performance

We need help with maximizing performance of our use of Berkeley XML DB. I am filling most of the 29 part question as listed by Oracle's BDB team.
Berkeley DB XML Performance Questionnaire
1. Describe the Performance area that you are measuring? What is the
current performance? What are your performance goals you hope to
achieve?
We are measuring the performance while loading a document during
web application startup. It is currently taking 10-12 seconds when
only one user is on the system. We are trying to do some testing to
get the load time when several users are on the system.
We would like the load time to be 5 seconds or less.
2. What Berkeley DB XML Version? Any optional configuration flags
specified? Are you running with any special patches? Please specify?
dbxml 2.4.13. No special patches.
3. What Berkeley DB Version? Any optional configuration flags
specified? Are you running with any special patches? Please Specify.
bdb 4.6.21. No special patches.
4. Processor name, speed and chipset?
Intel Xeon CPU 5150 2.66GHz
5. Operating System and Version?
Red Hat Enterprise Linux Relase 4 Update 6
6. Disk Drive Type and speed?
Don't have that information
7. File System Type? (such as EXT2, NTFS, Reiser)
EXT3
8. Physical Memory Available?
4GB
9. Are you using Replication (HA) with Berkeley DB XML? If so, please
describe the network you are using, and the number of Replica’s.
No
10. Are you using a Remote Filesystem (NFS) ? If so, for which
Berkeley DB XML/DB files?
No
11. What type of mutexes do you have configured? Did you specify
–with-mutex=? Specify what you find inn your config.log, search
for db_cv_mutex?
None. Did not specify -with-mutex during bdb compilation
12. Which API are you using (C++, Java, Perl, PHP, Python, other) ?
Which compiler and version?
Java 1.5
13. If you are using an Application Server or Web Server, please
provide the name and version?
Oracle Appication Server 10.1.3.4.0
14. Please provide your exact Environment Configuration Flags (include
anything specified in you DB_CONFIG file)
Default.
15. Please provide your Container Configuration Flags?
final EnvironmentConfig envConf = new EnvironmentConfig();
envConf.setAllowCreate(true); // If the environment does not
// exist, create it.
envConf.setInitializeCache(true); // Turn on the shared memory
// region.
envConf.setInitializeLocking(true); // Turn on the locking subsystem.
envConf.setInitializeLogging(true); // Turn on the logging subsystem.
envConf.setTransactional(true); // Turn on the transactional
// subsystem.
envConf.setLockDetectMode(LockDetectMode.MINWRITE);
envConf.setThreaded(true);
envConf.setErrorStream(System.err);
envConf.setCacheSize(1024*1024*64);
envConf.setMaxLockers(2000);
envConf.setMaxLocks(2000);
envConf.setMaxLockObjects(2000);
envConf.setTxnMaxActive(200);
envConf.setTxnWriteNoSync(true);
envConf.setMaxMutexes(40000);
16. How many XML Containers do you have? For each one please specify:
One.
1. The Container Configuration Flags
          XmlContainerConfig xmlContainerConfig = new XmlContainerConfig();
          xmlContainerConfig.setTransactional(true);
xmlContainerConfig.setIndexNodes(true);
xmlContainerConfig.setReadUncommitted(true);
2. How many documents?
Everytime the user logs in, the current xml document is loaded from
a oracle database table and put it in the Berkeley XML DB.
The documents get deleted from XML DB when the Oracle application
server container is stopped.
The number of documents should start with zero initially and it
will grow with every login.
3. What type (node or wholedoc)?
Node
4. Please indicate the minimum, maximum and average size of
documents?
The minimum is about 2MB and the maximum could 20MB. The average
mostly about 5MB.
5. Are you using document data? If so please describe how?
We are using document data only to save changes made
to the application data in a web application. The final save goes
to the relational database. Berkeley XML DB is just used to store
temporary data since going to the relational database for each change
will cause severe performance issues.
17. Please describe the shape of one of your typical documents? Please
do this by sending us a skeleton XML document.
Due to the sensitive nature of the data, I can provide XML schema instead.
18. What is the rate of document insertion/update required or
expected? Are you doing partial node updates (via XmlModify) or
replacing the document?
The document is inserted during user login. Any change made to the application
data grid or other data components gets saved in Berkeley DB. We also have
an automatic save every two minutes. The final save from the application
gets saved in a relational database.
19. What is the query rate required/expected?
Users will not be entering data rapidly. There will be lot of think time
before the users enter/modify data in the web application. This is a pilot
project but when we go live with this application, we will expect 25 users
at the same time.
20. XQuery -- supply some sample queries
1. Please provide the Query Plan
2. Are you using DBXML_INDEX_NODES?
Yes.
3. Display the indices you have defined for the specific query.
     XmlIndexSpecification spec = container.getIndexSpecification();
     // ids
     spec.addIndex("", "id", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     spec.addIndex("", "idref", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // index to cover AttributeValue/Description
     spec.addIndex("", "Description", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_SUBSTRING, XmlValue.STRING);
     // cover AttributeValue/@value
     spec.addIndex("", "value", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // item attribute values
     spec.addIndex("", "type", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // default index
     spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // save the spec to the container
     XmlUpdateContext uc = xmlManager.createUpdateContext();
     container.setIndexSpecification(spec, uc);
4. If this is a large query, please consider sending a smaller
query (and query plan) that demonstrates the problem.
21. Are you running with Transactions? If so please provide any
transactions flags you specify with any API calls.
Yes. READ_UNCOMMITED in some and READ_COMMITTED in other transactions.
22. If your application is transactional, are your log files stored on
the same disk as your containers/databases?
Yes.
23. Do you use AUTO_COMMIT?
     No.
24. Please list any non-transactional operations performed?
No.
25. How many threads of control are running? How many threads in read
only mode? How many threads are updating?
We use Berkeley XML DB within the context of a struts web application.
Each user logged into the web application will be running a bdb transactoin
within the context of a struts action thread.
26. Please include a paragraph describing the performance measurements
you have made. Please specifically list any Berkeley DB operations
where the performance is currently insufficient.
We are clocking 10-12 seconds of loading a document from dbd when
five users are on the system.
getContainer().getDocument(documentName);
27. What performance level do you hope to achieve?
We would like to get less than 5 seconds when 25 users are on the system.
28. Please send us the output of the following db_stat utility commands
after your application has been running under "normal" load for some
period of time:
% db_stat -h database environment -c
% db_stat -h database environment -l
% db_stat -h database environment -m
% db_stat -h database environment -r
% db_stat -h database environment -t
(These commands require the db_stat utility access a shared database
environment. If your application has a private environment, please
remove the DB_PRIVATE flag used when the environment is created, so
you can obtain these measurements. If removing the DB_PRIVATE flag
is not possible, let us know and we can discuss alternatives with
you.)
If your application has periods of "good" and "bad" performance,
please run the above list of commands several times, during both
good and bad periods, and additionally specify the -Z flags (so
the output of each command isn't cumulative).
When possible, please run basic system performance reporting tools
during the time you are measuring the application's performance.
For example, on UNIX systems, the vmstat and iostat utilities are
good choices.
Will give this information soon.
29. Are there any other significant applications running on this
system? Are you using Berkeley DB outside of Berkeley DB XML?
Please describe the application?
No to the first two questions.
The web application is an online review of test questions. The users
login and then review the items one by one. The relational database
holds the data in xml. During application load, the application
retrieves the xml and then saves it to bdb. While the user
is making changes to the data in the application, it writes those
changes to bdb. Finally when the user hits the SAVE button, the data
gets saved to the relational database. We also have an automatic save
every two minues, which saves bdb xml data and saves it to relational
database.
Thanks,
Madhav

Could it be that you simply do not have set up indexes to support your query? If so, you could do some basic testing using the dbxml shell:
milu@colinux:~/xpg > dbxml -h ~/dbenv
Joined existing environment
dbxml> setverbose 7 2
dbxml> open tv.dbxml
dbxml> listIndexes
dbxml> query     { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }
dbxml> queryplan { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }Verbosity will make the engine display some (rather cryptic) information on index usage. I can't remember where the output is explained; my feeling is that "V(...)" means the index is being used (which is good), but that observation may not be accurate. Note that some details in the setVerbose command could differ, as I'm using 2.4.16 while you're using 2.4.13.
Also, take a look at the query plan. You can post it here and some people will be able to diagnose it.
