Help with incremental bck

Hi,
I am trying to backup the dev and uat database to FRA using RMAN incremental backup option. The script is
# ~~~~~ start RMAN cold backup ~~~~~ #
rman target / nocatalog log=${LOG_FILE} <<EOF
run {
crosscheck backup;
crosscheck archivelog all;
delete noprompt expired backup;
delete noprompt obsolete;
delete noprompt expired archivelog all;
recover copy of database tag "img_cpy_incr_bkp" until time 'SYSDATE-2';
BACKUP INCREMENTAL LEVEL 1 FOR RECOVER OF COPY WITH TAG "img_cpy_incr_bkp" DATABASE;
exit;
EOF
Ok so from what I understand is that with this stratergy,
on day one RMAN will not find any level 0 bkp so it will do a full backup.
day 1, incremental backup
day 2, incremental backup again
day 3, incremental backup will be merged to level 0 bckp and day 0 bkp will be useless.
day 4, incremental backup will be merged to day 1 backup making day 1 backup as level 0.
day 5, incremental backup will be merged to day 2 backup making day 2 backup as level 0.
day 6, incremental backup will be merged to day 3 backup making day 3 backup as level 0.
Is that correct >>?? if so, then should I rerun the level 0 backup again on sunday ??? or should I keep on running this scrip.

Hi Dalji,
The size of the db is about 7 GB. I ran the script so as this is for the first time, should RMAN not do a level 0 backup ?? The following is the output of the script '

Please, help with Incremental Update for Linearized document.

Hi, here is my problem.
I'm working in my own annotation app. It incrementally updates pdfs. Works fine with most of the pdfs.
But i've found couple of pdfs, that was being corrupted after updating.
Here goes more details:
Single page-linearized pdf: when i've looked into pdf source, i found that page object has /Parent key which referencing to non-existing object. Normally, as i understand /Parent for page object is /Type /Pages objects with /Kids /Count etc.
12 0 obj
<</ArtBox[26 0 585.999 792]/BleedBox[26 0 586 792]/Contents[14 0 R 15 0 R 16 0 R 17 0 R 18 0 R 19 0 R 20 0 R 21 0 R]/CropBox[0 0 612 792]/MediaBox[0 0 612 792]/Parent 8 0 R/Resources 37 0 R/Rotate 0/TrimBox[26 0 586 792]/Type/Page>>
endobj
Parent 8 0 R - Is missing
But all pdf viewers are ok with that.
So, this pdf has two Xref tables:
36 0 obj
<</DecodeParms<</Columns 4/Predictor 12>>/Filter/FlateDecode/ID[<2C9B406A12A771465F8FE0D6A4DC67ED><9B829DD8BDB09849A00CA5D75E7 5CDF4>]/Index[10 54]/Info 9 0 R/Length 114/Prev 66739/Root 11 0 R/Size 64/Type/XRef/W[1 2 1]>>stream....
and Second one at the end of file.
5 0 obj
<</DecodeParms<</Columns 5/Predictor 12>>/Filter/FlateDecode/ID[<2C9B406A12A771465F8FE0D6A4DC67ED><9B829DD8BDB09849A00CA5D75E7 5CDF4>]/Info 9 0 R/Length 51/Root 11 0 R/Size 10/Type/XRef/W[1 3 1]>>stream
Linearized dict:
10 0 obj
<</Linearized 1/L 67043/O 12/E 48239/N 1/T 66738/H [ 534 185]>>
endobj
/T 66738 points to Xref table in 5 0 obj's stream
Now, when my annotation is stored: i'm adding the following object to the end of file:
8 0 obj <</Type /Pages/Count 1/Kids [ 12 0 R ]>>
endobj
I've create the missing 8 0 obj with Kids and /Count 1
12 0 obj<</Type /Page/Annots [ 65 0 R ]/ArtBox [ 26 0 585.999 792 ]/BleedBox [ 26 0 586 792 ]/Contents [ 14 0 R 15 0 R 16 0 R 17 0 R 18 0 R 19 0 R 20 0 R 21 0 R ]
/CropBox [ 0 0 612 792 ]/MediaBox [ 0 0 612 792 ]/Parent 8 0 R/Resources 37 0 R/Rotate 0/TrimBox [ 26 0 586 792 ]>>
endobj
it's page objects with new Reference to Annotation object which is:
65 0 obj<</Type /Annot/Contents (Test 2)/M (D:20120507172231+03'00')/Open true/P 12 0 R/Rect [ 0 0 100.000 100.000 ]/Subtype /Text/T(Test 1)>>
endobj
then goes my xref table
xref
8 1
0000067045 00000 n
0000067189 00000 n
0000067591 00000 n

And this totally broks my PDF.
Questing: /Prev in my trailer should point ot 5 0 obj or 36 0 obj?

Ok, thanks, and /Pref in my trailer should point to which xref? 5 0 (and the end of the original file) or 36 0 at the beginning?

Help with incrementing time (in excel)

Hi!
I need to find the difference between a start time and end time, calculate how much time has elapsed and divide that time period by a variable number of workers. (I have gotten that far with the formulas).
Then I need to take the resulting minutes in that time period per worker, and add it to the start time, and that is where I could use some help!
For an example, if the start time is 5:30 pm, and the end time is 6:00 pm, and I have 5 workers, I will get the amount of time per worker as 6 minutes. How would I create a formula to add the amount of time per worker back to the original start
time so that I can get a result of 5:36 PM?

1. In cell A2 I have:-
17:30:00
2. In cell B2 I have:-
18:00:00
3. In cell C2 I have:-
=(B2-A2)
This displays a result of:-
00:30:00
4. In cell D2 I have:-
5
5. In cell E2 I have:-
=(C2/D2)
This displays a result of:-
00:06:00
6. In cell F2 I have:-
=(A2+E2)
This displays a result of:-
17:36:00
Does that give you what you want?
The information above is in European time system (what Americans call, "military" time).
If you are in the US just input the times in the formats that you would normally do and you should get the same results as I do except in AM / PM format.

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.

USe the trace function to analyze what happens and what fails to happen in the code you showed. trace the conditional values to see if they are set up to allow a shot when you press the key

Help with XML, display data on swipe/click

Hello.
I am trying to create a moibile app that displays XML data. It's basically a phone book. I want the data to change when swiped. I can get the data in just fine. I can get it to display fine. I am not seeing the correct image first, however. I think it's a problem with my imagenum variable.
Then, I want to change what is displayed when the user clicks/swipes on the screen. How do I do that?

That helped. I get the correct images in the output, but not in the display. I also get the following error. Any chance you could help with that?

Issue with Incremental Recon?

We're facing an issue with incremental recons. If a full recon is run on a resource and an entry exists on the resource but NOT in IdM, the entry is put in the account index with a situation of UNMATCHED.....so far so good....
But if an IdM user is created for that entry, and incremental recon is run the incremental does not link up the resource account to the IdM user. It seems that the incremental doesn't handle the situation change of UNMATCHED to CONFIRMED?....Not sure if this is a bug (could've sworn that this used to work in a previous version of IdM) or if it's the intended functionality, and the full recon only is designed to handle this particular situation change....Thanks in advance for any insight!

No link. Because the account index already has this resource account flagged as UNMATCHED the incremental reconciliation ignores it.
You can manually assign the resource to the user account or perform a full reconciliation to resolve this UNMATCHED to CONFIRMED. This doesn't help in the case when there are a large number of UNMATCHED accounts or a full reconciliation takes a long time.

Really need help with MSI R7970-2PMD3GD5/OC:(

Greetings to all,
I really need help with my brand new MSI R7970-2PMD3GD5/OC. I've purchased it two days ago and I didn't really have time to test the card until yesterday. The card is I think way to hot for my "liking". It idles at 56c-60c, at full load in Heaven benchmark 3.0 in 1920x1080, extreme tessellation and 8xAA card reaches 95c-97c. Stock cloacks are 1010Mhz/1375Mhz and stock voltage is 1,174v. Case is being cooled by two Noctua NF-P12 fans. Also I tried lowering the voltage and "underclocking" the card to a standard 925Mhz in small increments, but it doesn't help at all. Each and every time it results in BSOD and dx dll errors and complete system failures. Replacing the card wouldn't be a problem if I lived in a "normal" country that has access to a steady supply. Retailer that sold me a card told me that only 5 cards total have been imported from the launch day and told me that i bought the "last" card in my country. They could order a replacement but it would take them more then a month to do so.:( Ohhh and one more thing I don't overclock, everything in my case is at their default values.
Recently, I read that "Amd released" a bios update for a standard reference boards that turns them into a "GHZ editions". Also lot of users report a lower voltage requirements and lower temps with that "boost bios". As I understand this card pcb is not Amd's reference board design, I could be wrong it's not that uncommon.. So I didn't want to risk warranty by flashing it to a position 1. Will MSI release the boost bios for this model of card? I am humbly asking MSI staff on how to proceed regarding this problem. I would be immensely grateful for any help you could provide.

what PC case you use exactly?
have you tried to open PC case side door and to retest?
Hi,
it's open case. If i close it the temps get even worse:(
They get better for other components, but not for gpu. Two Noctua NF-P12's are cooling the case, first one is positioned above gpu, left side next to cpu. Other is right beneath the gpu, right side of case. Just under the hdd section of the case. I tested each and every component with my backup card nv 8500gt. They function within the specified parameters. I'm getting somewhat worried.

I'm trying to do it this way:
I have declared an static counter to do the task, and is incrementing everytime the page is visited, but,
I want that depending of the user, it will print a different output, for example:
user "a", visted 3 times,
or user "b" visited 8 times.
I was thinking in a counter for each user, and to save it and restore it every time the user visits.
how can i do that?
<%! static int staticCounter = 1; %>
<%
if (request.getParameter("registereduser") != null){
           for (int i=0; i<cookies.length; i++) {
                 if (request.getParameter("registereduser").equals( cookies.getName() ) ){
     out.println("><BR> <H3>" + "Welcome again, "+ cookies[i].getName()+staticCounter++"<BR> </H3>");
%>

Help with scaling of chart

I have a problem manipulating the scale of the graph here.
in the VI that i attached, there's two chart. The one at the top is the problem that i am facing. I want to have a chart that has time on the x-scale in 24-hr format with increment of 1 hour. For the first chart to show every hourly value on the x-scale i have to stretch it too much and the incremental value becomes 30 minutes.
I intend to remain the size of the chart as the chart at the bottom.As you can see, the x-scale can not show every hourly value from 08:00 09:00 10:00 all the way to 20:00.
This should be what i want to get
| | | | | |
08:00 09:00 11:00 12:00 13:00 14:00 ... 20:00 x-scale
and maintaining the size as of
the chart at the bottom.
i've tried changing property node values for interval, max, min to no avail.
Thanks for any help

Hi Parker,
In your second graph you've got 8:00 - 12:00 - 20:00. What you need to do is replace the 12:00 by 9:00 (clic on 12:00) without adjusting any property.
The graph should then show the different times you want.
Hope this helps !

Help with unhappy beginner code...

Hello Java gurus,
I'm learning java and one of my class assignments is the old "mortgage calculator"... I made code up, compiled okay, but it won't execute. Gives me all sorts of errors. I THINK it's to do with the double vs int vs float... Please help!!! I've been playing with this and can't figure whats erroring. I know its prob something simple so please explain when you write back what I'm not understanding... Thank you! -nika
Assignment:
The monthly payment on mortgage loan of L dollars, at a rate of interest r is given by
Monthly payment = []
Where N is the number of years of mortgage. Write a program to find the monthly
payment for 30 years, for principals from $100,000 through $200,000(with increments
of $20,000) and interest rates of 6% through 10% (with increments of 0.5%). Print
monthly payment as a whole number (rounded off).
The output must be a neat table, similar to the following (your answers may be slightly
different because of rounding off).
Principal 6% 6.5% 7% 7.5% 8% 8.5% 9% 9.5% 10%
100000 600 632 665 699 733 768 804 840 877
120000 719 758 798 839 880 922 965 1009 1053
140000 � � � � � � � � �
160000 � � � � � � � � �
180000 � � � � � � � � �
200000 � � � � � � � � �
Hint: Use the following idea to compute (1 + r/12)12N
double temp = 1+r/12;
double temp1 = 1;
for (int i = 1; i<=12*N;i++)
temp1 = temp1*temp;
The final formula now becomes:
double mp = (L*(r/12)*temp1)/(temp1-1);
MY CODE:
import java.util.*;
class MortgagePmt {
public static void main(String args[])     {
int n = 30;
System.out.println("Mortgage Monthly Payment");
System.out.println("Principal 6.0% 6.5% 7.0% 7.5% 8.0% 8.5% 9.0% 9.5% 10.0% ");
for (int l = 100000; l<=200000; l=l+20000){
System.out.printf("%9d ",l);
for(double r = 6.0; r<=10.0; r=r+0.5){
double temp = 1+r%12;
double temp1 = 1;
for (int i = 1; i<=12*n;i++)
temp1 = temp1*temp;
double mp = (l*(r%12)*(temp1))/(temp1 - 1);
System.out.printf("%5.0f", mp);
System.out.println("");
}

You really need to do an analysis on your algo... there is NO WAY that it is correct.
MY CODE:
import java.util.*;
class MortgagePmt {
public static void main(String args[])     {
int n = 30;
System.out.println("Mortgage Monthly Payment");
System.out.println("Principal 6.0% 6.5% 7.0% 7.5% 8.0% 8.5% 9.0% 9.5% 10.0% ");
for (int l = 100000; l<=200000; l=l+20000){
System.out.printf("%9d ",l);
for(double r = 6.0; r<=10.0; r=r+0.5){
double temp = 1+r%12;
double temp1 = 1;What is this following little section for? temp1 comes out of there at 1.7x10^304... err, no way that is right. I do not believe there is that much anything in the world, let alone money.
for (int i = 1; i<=12*n;i++)
temp1 = temp1*temp;
double mp = (l*(r%12)*(temp1))/(temp1 - 1);
System.out.printf("%5.0f", mp);
System.out.println("");
}One of the best things you can do at this point, if it's not thee very best thing, is to get your debugger out and find out how to use it. Your code ran as you posted it, but your algorithm is not right and numbers you are calculating do not even make sense--all of them output as NaN (not a number). Take each feature of your assignment and code it 1 piece at a time tracing each seeing that the numbers you calculate make sense, and as you get that piece to work, move on to the next feature of your assignment. This way you don't write out a bunch of none tested code that you don't know what it is doing.
Throwing out code that you think is a solution that you do not know what it does and have no hope of fixing is no better than no solution at all--IMO it is far worse: you'll work attempting to fix it, not knowing what it is doing and all the time all you are building is your frustration.
(BTW: don't think I'm singling you out and speaking harshly to you--I've been there too. Sometimes it's better to just start over. Get a handle on what needs to be done. Get a working pencil and paper model, then describe the process in an algorithm, then code from that algorithm. Implement in steps and make sure each step works before moving on to the next. There is no magic in the computer--it won't make a bad process good--on the contrary it usually makes bad things worse, you have to design a good process first to implement a good process.)

Please help with Berkeley DB, desperate student here

I am a student and I have to complete a project within a week. Problem is, I never used Berkeley DB. What I am supposed to do is this...
Basically, in the Berkeley DB, I need to implement a replication scheme for distributed real-time databases.
The replication scheme simply allows a database which needs temporal data from another database to create a local replica of the data needed from the other database, and to receive the data in constant updates for a specified period of time. This scheme is beneficial because it eliminates the transmission delays from asking for the data every time it needs it from the remote datavabase. The recipient database will not need to keep sending a request for the data, it will automatically be sent to the replica in specified time increments, and for a specified period of time depending on what the transaction specifies.
The DB must support transactions. This is ideally meant for real time databases too.
Could you please tell me who could help me implement this? I really need help with this as soon as possible. I don't know where to get started regarding installing the correct DB, starting it up, and putting in sample data. I need a accurate step by step instruction for which DB to install, how to install it, and how to install sample data and how to access the data, and then how to proceed to modify it so that it can support the replication I mentioned above. Everything. I am new to this. ANyone's help would be the best. Thank you.

Alan, thanks for chiming in. I am in the process of reading the link you posted. Thank you. At this point, after having installed Berkeley DB 4.5.20, are there some preliminary steps that you can outline for me in terms of setting up a sample database and getting started? Is there a step-by-step somewhere on the site? After I do that, and then study the link you sent, it is my intent to dive into the code and make the adjustments/additions I need to model the algorithm I need to accomplish.
Disregard my time constraint which I mentioned earlier. I simply need to get everything running as a workable DB with data at this point, and then I can dive into the replication material. Let me know, and thanks for your help.
Ron, sorry for the multiple posts. I was initially trying to post in categories which I believed were relevant to my situation. I will stick to this thread.

Stored procedure to update particular key column with increment of +1

Hi,
This is my table
EMPID,NAME
1 SSS
2 AAA
I NEED STORED PROCEDURE TO UPDATE EMPID WITH INCREMENT OF +1.BASED ON
MAX(EMPID).fOr example if i execute stored procedure once it will update empid 2 as 3,
if i run same procedure again it will take increment +1 then emp id should be 4 like that i want output.
Any one please help me on this scenario...

But next time onwords we will update that datekey in fact table through stored procedure.stored procedure
will take only max(date_key) from fact table then update that key as like +1(logic n+1)
If i run stored procedure nextday it will update that record with increment +1.
we wil schedule this storedprocedure to run daily once.For this i need stored procedure..
I think you will clear now................
thxSo, are you saying you want to keep the same data you loaded "yesterday" but update the date_key so it appears as if it was from today?
Still seems strange: why aren't you loading today's data?
Also, you are assuming that the date_key in the date dimension table increments with no gaps: if it was sequence generated, that might not be true.

Help with Threads

I need help with threads. How can I break this code into teo threads without chaning the data objects at all? Producer will produce string line by line and consumer will take the line and search for the word. Help me please.
Thank you
public class WordFinder
* Main program opens the file given by the user as an argument and
* searches for the word given by the user. If the word is found,
* the line number on which the word occurs is displayed.
* @param args[0] Word to search for
* @param args[1] Name of file to search
public static void main(String[] args) throws IOException
// To keep track of how long the program runs we'll set the startTime
// variable to the current time in milliseconds and use that at
// the end of the program to find out how long we ran.
long startTime = System.currentTimeMillis();
String wordToFind;
String currentLine;
int lineCount = 0; // Keep track of line numbers
BufferedReader inputFile = null; // Needed to get compiler to quit
// complaining about uninitialized
// variables.
// Make sure we have 2 arguments passed to us
if (args.length < 2)
// Nope. Show user how to run and then exit with an error (1)
System.out.println("usage: java WordFinder <word> <file pathname>");
System.exit(1);
// So far, so good. Now try to open the file the user gave us as
// a parameter. We'll use a BufferedReader object to read the file
// so we can read one line at a time from the input. If opening the
// file fails, print an error message and exit with an error (1).
try
inputFile = new BufferedReader(new FileReader(args[1]));
catch (FileNotFoundException e)
System.out.println(args[1] + ": File not found or is not readable");
System.exit(1);
// Set the wordToFind variable to refer to args[0]. We don't
// really need to do this, but it makes our code more readable
wordToFind = args[0];
// We're going to read the file one line at a time. For each
// line, we'll create a StringTokenizer object to break the line
// into distinct words, checking each word to see if it's the same
// as the given search word.
// Read first line from the file
currentLine = inputFile.readLine();
while (currentLine != null) // Repeat until we reach EOF
// Have a valid input line, increment the counter
lineCount++;
// Create a StringTokenizer object over the current line
StringTokenizer tokens = new StringTokenizer(currentLine);
// Check each word in the string by accessing each token
while (tokens.hasMoreTokens())
// See if the next word is the one we're looking for and
// advance the token iterator to the next token
if (wordToFind.equals(tokens.nextToken()))
// Yes, display the current line number
System.out.println(wordToFind + " found on line " + lineCount);
// Read next line from the file
currentLine = inputFile.readLine();
} // while
// Done with the input file
inputFile.close();
// Display the running time of this program in milliseconds by
// subtracting the start time from the current time
System.out.println((System.currentTimeMillis() - startTime) + " milliseconds");
} // main
} // WordFinder

You may create Queue object. (I guess that you're already know QUEUE)
Then ... use producer thread to load input file into queue. (Enqueue)
Consumer ... dequeue
Queue can be empty because of
- Input file was read to EOF and Consumer had produced all queue.
or
- Cunsumer works too fast... So the queue is empty.
So, you may have to use ... wait() in Consumer in case of the queue is empty.
And use notify() in Producer to wake up consumer ...
Is this right ?
