Quick standby question

In a 10g dataguard scenario, let's say if something goes haywire at the primary, and we need to recover and restart the primary database with "reset logs". Then the standby would complain that it is missing archive logs files or something of that sort. Is the only way ( to preserve data integrity at the standby) is to recreate the standby database again from the newly recovered primary database? Or is there a quick way you can skip some of the log applies and ask it to continue with the current log file from the newly recovered primary db? I know, in most cases this wouldn't make sense that if logs are missing , then even if we manually do something and get the standby up, there is a possibility that due to data integrity , failover might cause issues.
Secondly lets , say the primary was fine and for some reason some archive log files were missing for the standby to apply. Are we doomed to recreate the standby again?

Once you open your primary with reset logs..the sequence number initiates from 1. Also your controlfile(s) & datafiles will have complete new Checkpoint SCN, which completely differs from your standby db.
So standby wouldn't recognize that so you wouldn't have any choice but to recreate a new standby DB.
Or is there a quick way you can skip some of the log applies and ask it to continue with the current log file from >>the newly recovered primary dbNo.
I know, in most cases this wouldn't make sense that if logs are missing , then even if we manually do something >>and get the standby up, there is a possibility that due to data integrity , failover might cause issues.what is this "then even if we manually do something " ? not clear.
Secondly lets , say the primary was fine and for......Yes.
and it is always better to follow the forum etiquette.

Hi all .hope all is well ..A quick trim question

Hi all
Hope all is well ......
I have a quick trim question I want to remove part of a string and I am finding it difficult to achieve what I need
I set the this.setTitle(); with this
String TitleName = "Epod Order For:    " + dlg.ShortFileName() +"    " + "Read Only";
    dlg.ShortFileName();
    this.setTitle(TitleName);
    setFieldsEditable(false);
[/code]
Now I what to use a jbutton to remove the read only part of the string. This is what I have so far
[code]
void EditjButton_actionPerformed(ActionEvent e) {
    String trim = this.getTitle();
      int stn;
      if ((stn = trim.lastIndexOf(' ')) != -2)
        trim = trim.substring(stn);
    this.setTitle(trim);
[/code]
Please can some one show me or tell me what I need to do. I am at a lose

there's several solutions:
// 1 :
//you do it twice because there's a space between "read" and "only"
int stn;
if ((stn = trim.lastIndexOf(' ')) != -1){
    trim = trim.substring(0,stn);
if ((stn = trim.lastIndexOf(' ')) != -1){
      trim = trim.substring(0,stn);
//2 :
//if the string to remove is always "Read Only":
if ((stn = trim.toUpperCase().lastIndexOf("READ ONLY")) != -1){
   trim = trim.substring(0,stn);
//3: use StringTokenizer:
StringTokenizer st=new StringTokenizer(trim," ");
    String result="";
    int count=st.countTokens();
    for(int i=0;i<count-2;i++){
      result+=st.nextToken()+" ";
    trim=result.trim();//remove the last spaceyou may find other solutions too...
perhaps solution 2 is better, because you can put it in a separate method and remove the string you want to...
somthing like:
public String removeEnd(String str, String toRemove){
int n;
String result=str;
if ((n = str.toUpperCase().lastIndexOf(toRemove.toUpperCase())) != -1){
   result= str.substring(0,stn);
return result;
}i haven't tried this method , but it may work...

Quick script question

Hi all,
Could anyone advise me if i can add anything within - header('Location: http://www.mysite.co.uk/thankyou.html'); in the script below so as the page
re- directs back to the main index page after a few seconds ?
Thankyou for any help.
<?php
$to = '[email protected]';
$subject = 'Feedback form results';
// prepare the message body
$message = '' . $_POST['Name'] . "\n";
$message .= '' . $_POST['E-mail'] . "\n";
$message .= '' . $_POST['Phone'] . "\n";
$message .= '' . $_POST['Message'];
// send the email
mail($to, $subject, $message, null, '');
header('Location: http://www.mysite.co.uk/thankyou.html');

Mr powers gave me that script so im rather confused at this point in time
I don't think I "gave" you that script. I might have corrected a problem with it, but I certainly didn't write the original script.
What you're using is far from perfect, but to suggest it would lay you open to MySQL injection attacks is ludicrous. For you to be prone to MySQL injection, you would need to be entering the data into a MySQL database, not sending it by email.
There is a malicious attack known as email header injection, which is a serious problem with many PHP email processing scripts. However, to be prone to email header injection, you would need to use the fourth argument of mail() to insert form data into the email headers. Since your fourth argument is null, that danger doesn't exist.
One thing that might be worth doing is checking that the email address doesn't contain a lot of illegal characters, because that's a common feature of header injection attacks. This is how I would tidy up your script:
<?php
$suspect = '/Content-Type:|Bcc:|Cc:/i';
// send the message only if the E-mail field looks clean
if (preg_match($suspect, $_POST['E-mail'])) {
header('Location: http://www.example.com/sorry.html');
exit;
} else {
$to = '[email protected]';
$subject = 'Feedback form results';
// prepare the message body
$message = 'Name: ' . $_POST['Name'] . "\n";
$message .= 'E-mail: ' . $_POST['E-mail'] . "\n";
$message .= 'Phone: ' . $_POST['Phone'] . "\n";
$message .= 'Message: ' . $_POST['Message'];
// send the email
mail($to, $subject, $message);
header('Location: http://www.example.com/thankyou.html');
exit;
?>
Create a new page called sorry.html, with a message along the lines of "Sorry, there was an error sending your message". Don't put anything about illegal attacks. Just be neutral.
By the way, when posting questions here, don't use meaningless subject lines, such as "Quick script question". If you're posting here, it's almost certain to be a question about a script. It doesn't matter whether it's quick. Use the subject line to tell people what it's about.

Ye olde "delete archivelogs in standby" question

11.2.0.2.0
According to note
Configure RMAN to purge archivelogs after applied on standby [ID 728053.1]
oracle should remove archive logs if we have deletion policy set to "delete applied on standby" which I have set on primary and standby. Monitoring the alert log we see
"Deleted Oracle managed file /path/to/an/archive/log"
so we think cool, its removing them automatically. Question is, when does it delete them? Right now my standby is in sync, yet my alert log is only sporadically showing my logs being deleted which were applied hours ago which I can visibly verify.

so what I take from this is that if there is any space available in the 15% free then Oracle waits to be woken up by the receipt of a log from primary, sees that theres less than 15% free and deletes logs to below that limit. however, if the space free is less than the space used then oracle wakes up itself and deletes the logs. Cool.

Urgent help with quick translation questions

Hello,
I am somewhat new to Java. I have a translation to hand in in a few hours (French to English). Argh! I have questions on how I worded some parts of the translation (and also if I understood it right). Could you, great developers, please take a look and see if what I wrote makes sense? I've put *** around the words I wasn't sure about. If it sounds strange or is just plain wrong, please let know. I also separated two terms with a slash, when I was in doubt of which one was the best.
Many thanks in advance.
1) Tips- Always ***derive*** the exceptions java.lang.Exception and java.lang.RuntimeException.
Since these exceptions have an excessively broad meaning, ***the calling layers will not know how to
distinguish the message sent from the other exceptions that may also be passed to them.***
2) The use of the finally block does not require a catch block. Therefore, exceptions may be passed back to the
calling layers, while effectively freeing resources ***attributed*** locally
3) TIPS- Declare the order for SQL ***statements/elements*** in the constant declaration section (private static final).
Although this recommendation slightly hinders reading, it can have a significant impact on performance. In fact, since
the layers of access to data are ***low level access***, their optimization may be readily felt from the user’s
perspective.
4) Use “inlining.”
Inlining is a technique used by the Java compiler. Whenever possible, during compilation, the compiler
copies the body of a method in place of its call, rather than executing a ***memory jump to the method***.
In the example below, the "inline" code will run twice as fast as the ***method call***
5)tips - ***Reset the references to large objects such as arrays to null.***
Null in Java represents a reference which has not been ***set/established.*** After using a variable with a
large size, it must be ***reassigned a null value.*** This allows the garbage collector to quickly ***recycle the
memory allocated*** for the variable
6) TIPS Limit the indexed access to arrays.
Access to an array element is costly in terms of performance because it is necessary to invoke a verification
that ***the index was not exceeded.***
7) tips- Avoid the use of the “Double-Checked Locking” mechanism.
This code does not always work in a multi-threaded environment. The run-time behavior ***even depends on
compilers.*** Thus, use the following ***singleton implementation:***
8) Presumably, this implementation is less efficient than the previous one, since it seems to perform ***a prior
initialization (as opposed to an initialization on demand)***. In fact, at runtime, the initialization block of a
(static) class is called when the keyword MonSingleton appears, whether there is a call to getInstance() or
not. However, since ***this is a singleton***, any occurrence of the keyword will be immediately followed by a
call to getInstance(). ***Prior or on demand initializations*** are therefore equivalent.
If, however, a more complex initialization must take place during the actual call to getInstance, ***a standard
synchronization mechanism may be implemented, subsequently:***
9) Use the min and max values defined in the java.lang package classes that encapsulate the
primitive numeric types.
To compare an attribute or variable of primitive type integer or real (byte, short, int, long, float or double) to
***an extreme value of this type***, use the predefined constants and not the values themselves.

1) Tips- Always ***derive*** the exceptions java.lang.Exception and java.lang.RuntimeException.***inherit from***
***the calling layers will not know how to

while effectively freeing resources ***attributed*** locally***allocated*** locally.
3) TIPS- Declare the order for SQL ***statements/elements*** in the constant declaration section (private static final).***statements***, but go back to the author. There is no such thing as a 'constant declaration section' in Java.
Although this recommendation slightly hinders reading, it can have a significant impact on performance. In fact, since
the layers of access to data are ***low level access***, their optimization may be readily felt from the user’s
perspective.Again refer to the author. This isn't true. It will make hardly any difference to the performance. It is more important from a style perspective.
4) Use “inlining.”
Inlining is a technique used by the Java compiler. Whenever possible, during compilation, the compiler
copies the body of a method in place of its call, rather than executing a ***memory jump to the method***.
In the example below, the "inline" code will run twice as fast as the ***method call***Refer to the author. This entire paragraph is completely untrue. There is no such thing as 'inlining' in Java, or rather there is no way to obey the instruction given to 'use it'. The compiler will or won't inline of its own accord, nothing you can do about it.
5)tips - ***Reset the references to large objects such as arrays to null.***Correct, but refer to the author. This is generally considered bad practice, not good.
Null in Java represents a reference which has not been ***set/established.******Initialized***
After using a variable with a
large size, it must be ***reassigned a null value.*** This allows the garbage collector to quickly ***recycle the
memory allocated*** for the variableAgain refer author. Correct scoping of variables is a much better solution than this.
***the index was not exceeded.******the index was not out of range***
The run-time behavior ***even depends on compilers.***Probably a correct translation but the statement is incorrect. Refer to the author. It does not depend on the compiler. It depends on the version of the JVM specification that is being adhered to by the implementation.
Thus, use the following ***singleton implementation:***Correct.
it seems to perform ***a prior initialization (as opposed to an initialization on demand)***.I would change 'prior' to 'automatic pre-'.
***this is a singleton***That's OK.
***Prior or on demand initializations***Change 'prior' to 'automatic'.
***a standard
synchronization mechanism may be implemented, subsequently:***I think this is nonsense. I would need to see the entire paragraph.
***an extreme value of this type******this type's minimum or maximum values***
I would say your author is more in need of a technical reviewer than a translator at this stage. There are far too serious technical errors in this short sample for comfort. The text isn't publishable as is.

Quick NativeWindow questions.

Hi,
Two Quick Questions about native window actions (I am using AIR with HTML and JS):
1. How do you "refer" to minimize button ? - So, when a user clicks minimize, it should do an action defined in javascript.
2. How to define click event for System tray icon ? - So I can display something when my system tray icon is double-clicked.
Thanks.

1. Add an event listener to the window.nativeWindow object, listening for the NativeWindowDisplayStateEvent.DISPLAY_STATE_CHANGING or DISPLAY_STATE_CHANGE events.
2. Add an event listener to your SystemTrayIcon object. You can listen for click, mouseUp or mouseDown events, but doubleClick events are not dispatched by this object.

Yet another standby question...

Hi gurus,
Please help to resolve the quiz. I have completed manual physical standby installation. It is up and running. I then decided to install Grid Control and to use Data Guard for the standby creation. I've successfully installed GC, deployed all agents, I can see my previous standbys, life is good in short. Now, when I am trying to create the second standby for my production database using the Data Guard I stuck on a logical question:
On the step 3 of Data Guard standby creation, there is a note, saying:
The instance name (also referred to as the SID) must be unique on the standby host.
Yeah, fair enough. But i can't understand what should I do next? I have:
db_name YELLOW - primary prod
db_name YELLOW - standby prod 1st
and i need db_name YELLOW - standby 2nd
But I can't create it on the same server where the first standby resides.. What options do I have? Do I need to create the second standby on another server? Do I need to kill 1st standby? Is there any way to avoid this conflict? I am confused. I have no equipment for TWO standby servers... I thought I can install there up to 9 standbys.. But it seems to be a problem.. And definitely, I cannot give my second standby other name than YELLOW as all my applications are strongly tied on db_name...
Friends, please clarify this if you can. I am kinda lost in here..
Thanks as usual,
Maria

well, that's a good question! :)
because I don't have spare server for the standby. the question is not about: 'should I or should not put more than one standbys in one server' , but more about: 'is there any way to put two standbys with the identical db_names in one server'. I know that I probably sound unprofessional, but I just wanna know.. If the answer is 'no way', I will kill the first standby then and recreate the second one using DG with the correct name.
Thanks for writing to me,
M.

Standby question

Yes or No, if yes how .. if no please let me.. please helpNo, that is logically impossible: a physical standby is byte-for-byte identical to the primary, but a logical standby may be very different. Even though it will have been instantiated from a physical standby, it will have diverged: different dbname and dbid, the physical and logical structures will have changed, it may have additional objects, it may have objects that are not maintained.

10gr2 standard edition standby question - archive log shipping

Hello,
I have 2 servers with 10gr2 standard edition, one is production(primary) and secondary is standby on windows platform. To keep standby synchronized i use a script to copy archived logs from primary to standby and applying manually (with scripts).
My question is: can i use redo transport service in order to copy archivelogs from primary to standby ?
Thank you in advance.

Hi,
It is a bit of topic.
According to the Licensing Document page 10 DataGuard is not supported for standard edition.

Router HSRP Active/Standby question

Hello,
Can I use following command to setup HSRP Active/Standby mode for both router ?
Router A:
ip address 10.10.228.202 255.255.255.248
standby 3 ip 10.10.228.201
standby 3 preempt
Router B:
ip address 10.10.228.203 255.255.255.248
standby 3 ip 10.10.228.201
standby 3 preempt
standby 3 track 1 decrement 10
standby 3 track 2 decrement 10
Thanks

Wilson,
we don't know what objects you're tracking, so it's a little bit difficult to answer the question.
You use the default priorities on both routers (100), so, as long as track objects 1 and 2 are up, Router B will be the active router, because it has the higher IP address.
If track object 1 or 2 goes down, Router B's priority will be reduced to 90 (or 80 if both are down at the same time), so Router A will become active, because preemption is enabled.
If the track object(s) change to up, Router B will take over again, because it also has preemtion enabled.
Correction:
Preemption only comes into play when the local priority is higher than the priority of the current active router. In your examle, the priorities on RA and RB have the same values. The IP addresses serve as a tie breaker only in the initial phase, the preemption feature doesn't consider the IP addresses later on.
Consequence: Router A continues beeing the active router.

Rebuild standby question

Good morning,
I am puzzled by this in rebuilding standby process. I remember see this:
Before run “rman dup for standby …” you do “ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=defer..” in primary db.
After finish RMAN dup and start MRP process you do “ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=enable..” in primary db.
So during this RMAN dup time period (it can take several hours) we don’t ship any archive logs to standby and when RMAN finishes it inevitably has a lot of logs not in standby side. Does this mean that we definitely are going to have log gap after the RMAN dup? Do we need to manually copy those archive logs from primary to standby in order for MRP to apply them? What is the main reason we disable the log ship during rman dup period?
Thanks a lot in advance for sharing your insight!!
Shirley

The main reason to disable shipping during the dup is nothing exists to apply them to. If you are using RMAN to dup a standby you probably will move the RMAN backup and the current logs over before you issue the dup command which is something like this:
RMAN> run {
allocate channel C1 device type disk;
allocate auxiliary channel C2 device type disk;
duplicate target database for standby nofilenamecheck;
Once you have the new Standby you can "enable" shipping again. I generally do a log switch on the primary and used the v$ view v$archived_log to check the results. v$archived_log will show logs on both primary and standby, use the DEST_ID to check just one side and order by sequence#.
The alert log on both sides are a great source of information.
Does this answer your question?
Thoiught about this more. You could also try:
duplicate target database for standby from active database;
I have never tested this myself.

TDMS - Quick winning Question....

We are reviewing TDMS
We have one quick question ....
After 4 years of Journey & age of landscpae, becuase of SPDD & SPAU was not handled incidentally during "different" patch upgrades. and we assume there is slight inconsistency of " Repository objects" " Dictionary Objects"...
We want to acheive In short
We want to build a Development System which should be in synch of " Repository objects" " Dictionary Objects"... with out any master & application data with TDMS ?
Can we acheive this or not ...
TDMS provides all other luxuries, but we could get a straight confirmation as requirement as above.
Pl Help

PR

Hi Sriniwas
If you are asking this question to make a buying decision about TDMS then i would suggest that you get in touch with your SAP customer engagement manager (account manager) and ask him to present you all the capabilities and functionalities of TDMS.
Current version of TDMS offer multiple options and functionalities which may be useful for you.
Now regarding the query that you have asked -
If I understood you correctly you are looking for a functionality using which you want to create a development system which is a copy of your production system such that only repository gets copied over from production to the development system and all the client dependent application data is filtered. In the end you will have your development system which is in perfect sync as far as repository and DDIC is concerned.
The above can certainly be achieved using the TDMS Shell process within TDMS. TDMS Shell is also used as a process to prepare your receiver system for TDMS data transfer.
I hope this info helps
