Urgent Suggestions needed for best way to solve the problm

Hi Everybody,
I am working on an application which has to graphically show the data in the database. We are using JSP for the front end (the view for the time being will be simple, with text boxes and frames and DHTML) and tomcat as the Server. The data is huge and there ain't much business logic involvd (the user when he clicks on a URL I get the data pertaining to that particular table or column). Now my question is can Tomcat handle such huge data. What do u guys suggest, should I cache data at my server and server to the clients (instead of connecting to the DB for each and every request) If yes, can you guys please suggest a good way to cache data, I mean hat TableModel or HashMap will store data from different tables. Also the DB isn't updated for a while everyday. Also let me know if any of u guys still think a 3 -tier approach is advisable instead of the 2-tir approach
Thanks guys who made it this far

Well, of course a 3-tier approach is advisable. Also, yes, Tomcat can handle what you are doing. As far as caching data on the server, that is going to depend on your database and other requirements. Now about the graphical nature, you aren't going to be able to use JSP to draw graphics. The only way you can do it is to draw the graphics on the server-side, write out JPG files, but then the JSP won't know anything about where the image is, unless you always write the same number of images, in the same place, every time. Otherwise, you need an Applet. Hope that helps.

Hi, we need to create the test environment from our production for oracle AP Imaging. we have soa,ipm,ucm and capture managed servers in our weblogic..
Can anyone tell me what is the best way to cloning the application from different environment, the test and production are in different physical server.
Can I just tar the weblogic file system and untar it to the new server and make the necessary changes?
Can anyone share their experiences and how to with me?
Thank in advance.
Katherine

Hi Katherine,
yes and no . You need as well weblogic + soa files as the database schemas (soa_infra, mds...).

Hi all! What is the best way to create the correct space for baseball jersey names and numbers? along with making sure they are the right size for large printing.

What is the best way to create the correct space for baseball jersey names and numbers? along with making sure they are the right size for large printing.

Buying more hard drive space is a very valid option, here. Editing takes up lots of room, you should never discount the idea of adding more when you need it.
Another possibility is exporting to MXF OP1a using the AVC-I codec. It's not lossless, but it is Master quality. Plus the file size is a LOT smaller, so it may suit your needs.

WITH plus /*+ MATERIALIZE */ hint can do good to you.
see below the test case.
SQL> create table hx_my_tbl as select level id, 'karthick' name from dual connect by level <= 5
2 /
Table created.
SQL> insert into hx_my_tbl select level id, 'vimal' name from dual connect by level <= 5
2 /
5 rows created.
SQL> create index hx_my_tbl_idx on hx_my_tbl(id)
2 /
Index created.
SQL> commit;
Commit complete.
SQL> exec dbms_stats.gather_table_stats(user,'hx_my_tbl',cascade=>true)
PL/SQL procedure successfully completed.
Now this a normal inline view
SQL> select a.id, b.id, a.name, b.name
2 from (select id, name from hx_my_tbl where id = 1) a,
3 (select id, name from hx_my_tbl where id = 1) b
4 where a.id = b.id
5 and a.name <> b.name
6 /
Execution Plan
0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=7 Card=2 Bytes=48)
1 0 HASH JOIN (Cost=7 Card=2 Bytes=48)
2 1 TABLE ACCESS (BY INDEX ROWID) OF 'HX_MY_TBL' (TABLE) (Cost=3 Card=2 Bytes=24)
3 2 INDEX (RANGE SCAN) OF 'HX_MY_TBL_IDX' (INDEX) (Cost=1 Card=2)
4 1 TABLE ACCESS (BY INDEX ROWID) OF 'HX_MY_TBL' (TABLE) (Cost=3 Card=2 Bytes=24)
5 4 INDEX (RANGE SCAN) OF 'HX_MY_TBL_IDX' (INDEX) (Cost=1 Card=2)
Now i use the with with the materialize hint
SQL> with my_view as (select /*+ MATERIALIZE */ id, name from hx_my_tbl where id = 1)
2 select a.id, b.id, a.name, b.name
3 from my_view a,
4 my_view b
5 where a.id = b.id
6 and a.name <> b.name
7 /
Execution Plan
0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=8 Card=1 Bytes=46)
1 0 TEMP TABLE TRANSFORMATION
2 1 LOAD AS SELECT
3 2 TABLE ACCESS (BY INDEX ROWID) OF 'HX_MY_TBL' (TABLE) (Cost=3 Card=2 Bytes=24)
4 3 INDEX (RANGE SCAN) OF 'HX_MY_TBL_IDX' (INDEX) (Cost=1 Card=2)
5 1 HASH JOIN (Cost=5 Card=1 Bytes=46)
6 5 VIEW (Cost=2 Card=2 Bytes=46)
7 6 TABLE ACCESS (FULL) OF 'SYS_TEMP_0FD9D6967_3C610F9' (TABLE (TEMP)) (Cost=2 Card=2 Bytes=24)
8 5 VIEW (Cost=2 Card=2 Bytes=46)
9 8 TABLE ACCESS (FULL) OF 'SYS_TEMP_0FD9D6967_3C610F9' (TABLE (TEMP)) (Cost=2 Card=2 Bytes=24)
here you can see the table is accessed only once then only the result set generated by the WITH is accessed.
Thanks,
Karthick.

HT1198 I shared disk space and my iPhoto library as described in this article. When creating the disk image, I thought I had set aside enough space to allow for growth (50G). I'm running out of space. What's the best way to increase the disk image size?

Done. Thank you, Allan.
The sparse image article you sent a link to needs a little updating (or there's some variability in prompts (no password was required) with my OS and/or Disk Utility version), but it worked.
Phew! It would have been much more time consuming to use Time Machine to recover all my photos after repartitioning the drive.

How can I get the default value of a particular preference in FireFox?.
I know I can see the default value for some of the preferences in about:config but, I need a programatic way to get the default value.
I see some that there are values for preferences in firefox.cs but I am not certain that these are being used as the default values for preferences. prefs.js in user's profile only has the updated values and not the default values.
Any help towards acheiving this programtically is greatly appreciated.
If the default values are stored in a file, kindly let me know the format in which it is stored for me to parse it programatically.

Dear Friend,
Here when you have the callableSattement as ?=proc(?), the first ? is an output parameter. So you should register it as out parameter using registeroutparameter.
Then you can get the value from the outparameter using callablestatement.getXXX().
Try that way.

Using Microsoft Exchange to access Gmail (Google Apps for Business) contacts, what is the best way to sync the Corporate Directory?

Using Microsoft Exchange to access Gmail (Google Apps for Business) contacts, what is the best way to sync the Corporate Directory? For instance, we have 40 staff members and wish to populate each phone with the Gmail profile. Right now we have a third party Android app that does this and copies my contacts to each phone. This is problematic. Any solutions to populate a phone with email and phone contacts? Even it it requires double entry for me...thats ok.

Oh, I meant Leopard does do more than Tiger Server.
I don't know enough about Server, even less abut Syncing.
SL is to new, not enough time to iron out the kinks yet imho.
One day SL will be better than Leo, but...
I'd ask over in server...

Or perhaps Collaboration Services...

They may even have a different opinion on SL.

Iphone 4s coming friday, what is the best way to get the notes content from iphone 4 to 4s without doing a restore? i want the new phone to be totally new but not sure how to get notes content across.

What is the best way to get the notes content from iphone 4 to 4s without doing a restore? i want the new phone to be totally new but not sure how to get notes content across. If I do a restore as I have when previously from one iphone to another it has shown (in settings, usage) the cumulative usage from previous phones so all the hours of calls on all previous iphones will be displayed even though its brand new. Anyone know how I can get my notes (from standard iphone notes app) to my new iphone 4s without restoring from previous iphone 4. Thanks for any help offered.

First, if you haven't updated to iTunes 10.5, please update now as you will need it for the iPhone 4S and iOS 5.
Once you're done installing iTunes 10.5, open it. Connect your iPhone to iTunes using the USB cable. Once your iPhone pops up right click on it. For example: an iPhone will appear and it will say "Ryan's iPhone."
Right click on it and select "Backup" from the dropdown menu. It will start backing up. This should backup your notes.
Please tell me if you have any problems with backing up.
Once you backup and get your iPhone 4S, you must follow these steps. If you don't follow these steps, you will not be able to get your notes on your new iPhone 4S.
Open up iTunes again then right click on your device (iPhone 4S). Once you do you will see a dropdown menu. It will say "Restore from Backup..." Select this and it'll ask for a backup, select it from the dropdown menu. For example "Ryan's iPhone - October 12, 2011." Pick that and it will restore to your backup. Do this when you get your iPhone 4S so you will not lose anything. Even though you're restoring, you're getting back, since you're getting the previous settings, notes, contacts, mail and other settings from your old iPhone. You'll still have Siri though! So, restore when you first get it. Also frequently backup your device, as it will be worth it. You can restore from a backup if something goes wrong or save your data for a future update.
Once you do that, you should have your notes on your new iPhone 4S and iOS 5.
Please tell me if you need any help.
I hoped I answered your questions and solved your problem!

Best way to show the following data?

Hi Experts,
I am designing a validation solution in java webdynpro.
I need to process 1000 records against certain logic and need to show the errors in the interface..Each record has more than 30 columns. I would like to get your suggestions on,
1. How to display 1000 records with nearly 30 columns? A normal table with scrolling is enough or i need to split into 2 or 3 tabs based on some grouping and show these 1000 records?
2. What would be the best way to show the error messages on these records?, Is it advisable to show the error messages on a tooltip? Is it possible to show a tooltip for each record in a table?
Any suggestions would be really helpful for my work...
Thanks in advance..
Regards,
Senthil
Edited by: Senthilkumar.Paulchamy on Jun 23, 2011 9:18 PM

Hi,
Depending on your data would use a TableColumnGroup to group your 30 columns under a common header (displaying only the most significant data)
Expanding the row would then show all 30 columns' data
To display the errors, I would display the common header rows in bold red to make them stand out from the non-erroneous rows.
Furthermore, I would add a toggle button, to alternate between 'all records' and 'erroneous records only'
Best,
Robin

Best way of partitioning the huge size table in oracle 11gr2

hi,
OS: linux
DB: oracle 11gR2
table size is about 2T and single table space with multiple dbf files in ASM,
table partition with dbms.redefinition is running past 2 days (range partition).. its running but not that fast..
note: exchange partition is too slow.. hence not used..
what is the best way of doing the huge size table partition. please suggest, thanks.

>

>
A few questions
1. Is that an OLTP or OLAP table?
2. Is all of the data still needed online or is some of it archivable?
3. What type of partitiioning are you doing? RANGE? LIST? COMPOSITE?
4. Why do you you say 'exchange partition is too slow' - did you do a test?
For example if data will be partitioned by create date then one stragety is to initially put all existing data into the root partition of a range partitioned table. Then you can start using new partitions for new incoming data and take your time to partition the current data.
