RMAN question concerning Physical Standby

We have a database in a two-server Dataguard environment. We use RMAN to backup up the Primary database (on the server CORE), but we do not backup the Physical Standby (this was recommended by our vendor).
Once a month, I switchover the Primary database (on the server CORE) over to the Physical Standby database (which is on the server DG). I apply Linux patches to the CORE server and reboot. I then bring up the database as Physical Standby (using "startup nomount", followed by "alter database mount standby database" and then "alter database recover managed standby database disconnect from session"), and then I do a switchover and make it the Primary again.
My question is, after I bring up the database on the server CORE as a Physical Standby, and before I do a switchover to make it the Primary again, can I use RMAN to run a "restore database validate" to see if my backups are currently valid, or would this not give me the expected results since I am the Physical Standby?
Thanks in advance.

You should have any problem. What you're doing is similar to a a "rolling upgrade". When your physical to production environment make sure put the dest_2 in defer. Is your current physical standby works now? If so, there's problem.

RMAN question

Hi gurus;
I am using one RMAN script for 9.2.0.8 db,its:
rman target / <<EOF
SQL 'ALTER SYSTEM ARCHIVE LOG CURRENT';
DELETE NOPROMPT OBSOLETE;
BACKUP DATABASE PLUS ARCHIVELOG ;
crosscheck backup;
crosscheck archivelog all;
RMAN> show all;
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/xx/ctrl_%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 1;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/xx/backup_db_s%s_p%p_%T' MAXPIECESIZE 3000 M;
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/xxx/snapcf_VIS.f';
My question is i need one script (RMAN) for it will run in day 3 times and take backup of all arhive than it will delete exsiting archive in archive log destinaton, coz for archive destination i have disk size problem.
Is anyone help me?

First of all, usually you would first do a crosscheck and then the DELETE
I recommend to split up the tasks into two scripts. One for the nightly backup called "fbackup.cmd". The contents would look like:
run {
allocate channel ch1 type 'sbt_tape' parms '<your tape storage parameter>';
backup
incremental level 0
format 'df_%d_t%t_s%s_p%p'
(database include current controlfile);
sql 'ALTER SYSTEM ARCHIVE LOG CURRENT';
}And one for the archivelogs only, that runs multiple time across the day called: "archbackup.cmd"
run {
allocate channel ch1 type 'sbt_tape' parms '<your tape storage parameters>';
backup
incremental level 0
format 'arch_%d_t%t_s%s_p%p'
(archivelog all delete input );
sql 'ALTER SYSTEM ARCHIVE LOG CURRENT';
}This way a crosscheck is not needed, because RMAN itself deletes the archives and updates the catalog.
Both scripts can be called with the following command line:
rman target / [rcvcat user/passwd@catalogdb] cmdfile [fbackup.cmd|archbackup.cmd]
Hope this helps.

RMAN question(any option to bypass any internal RMAN errors)

Hi All,
Os : Solaris 10
db : 10.2.0.4
in rman backup script i have mentioned as below before firing backup
CONFIGURE EXCLUDE FOR TABLESPACE 'ABC';
CONFIGURE EXCLUDE FOR TABLESPACE 'DEVELOPER';
CONFIGURE EXCLUDE FOR TABLESPACE 'BACKUP';
CONFIGURE EXCLUDE FOR TABLESPACE 'REPORT';
one of our dba has dropped one tablespace which is not imporatant (ABC)...
same day when backup has fired from cron ..backup has got failed and thrown following error
RMAN-20202: tablespace not found in the recovery catalog
RMAN-06019: could not translate tablespace name "ABC"
My question : is there any way to bypass any such errors (like in "imp" command IGNORE option)
any such options available at RMAN level..?
Thanks a lot
Vamshi

Hi;
Please check below notes which could be helpful for your issue:

RMAN questions

New to Oracle DBA world. Some basic quetions, I will appreciate for help.
what is the meaning of this
restore database validate;
is it good to include this in daily full backup script.
My rman destination is sbt (tape). I want to copy some os files also on the tape with rman. what is the syntax to include that in the rman command 'host cp ----' ;.
OS is sun solaris and databases are oracle 9i and 10g . thanks

Check this for your restore validate question:
http://download-east.oracle.com/docs/cd/B10501_01/server.920/a96565/rcmsynta46.htm#93304
You CAN NOT take file system backups to tape using RMAN. Which Media Manager software are you using to take RMAN backups on tape?? If that MM provides you an interface to take OS filesystem backup then you have to use that (outside from RMAN). Like OSB provide you to take RMAN plus file system backup option. Check your media manager software for more details on this.

Advanced Security question

I hope I'm asking this question right. Do any of you know if Advanced Security supports IOS module 12.4 13 on a 2811?

Hi,
For your first question about exception list: If Windows Firewall is blocking a program and you want to allow that program to communicate through the firewall, you can usually do that by selecting the program in the list of allowed programs (also called
the exceptions list) in Windows Firewall.
For the second question, that means Firewall allow your Skype to communicate through Firewall.
You can add items manually, or just choose following settings after installing or configuring first open network app:

Able to advance past question with wrong answer

The following applies to a multiple choice question in Captivate 3.0.1 Build 589. You are able to advance through a question even if you have selected the wrong answer by doing the following:
Answer a question incorrectly. A box saying "Try Again" pops up.
Press the previous button on the Captivate navigation bar to go to the previous slide.
Press the next button on the Captivate navigation bar to advance to the question slide. The incorrect answer is still selected.
Press the next button on the Captivate navigation bar while the incorrect answer is still selected.
Captivate advances, even though you have not answered the question correctly.
This is a major issue for me for two reasons. A) It allows learners to advance without demonstrating that they learned what we are trying to teach them, and B) It actually misinforms learners by letting them advance with the wrong answer selected, so they may actually believe that what they answered is correct.
Does anyone else have this problem? Anyone have any ideas how I can fix it?
Thanks very much for your help,
Marc

Marc,
Do you know what wrong answer options you have selected? If you do not want the user to advance when they select a wrong answer, you can make sure they do not. On the question slides of interest, go to Edit Question. Select Options. Under "If wrong answer" section, select Infinite attempts. Now the user will not be able to advance until he/she gets the answer correct. The only side note on this is the user will get the Incorrect Answer message only one time. After that there are no response message until the correct answer is chosen. Hope this helps.

LocalConnection Advanced use question

Does anybody know if it is actually possible to have two
flash movies talk to each other when one is in an iframe at a
different domain and one is in the page containing the iframe?
I spent quite a bit of time yesterday going through varoius
permutaions on naming the connections. The closest I got to
anythign was when I got my sender movie in Flash to successfully
talk to the reciever movie in the browser, that was accomplished
having an underscore in front fo the connection name in sender and
reciever. But when the reciever swf is in a page containing an
iframe with the sender swf nothing appears to happen.
Since I got flash player (and an executable version of the
sender) to commicate with the browser based reciever I figure this
should be possible. But i can't seem to figure out what I'm missing
in the browser based versions.
The intent of this exercise is to allow technology I am
helping to delop to be included in a page using an iframe while
providing feedback to listener movie in the site the iframe is
embedded in. From there we would provide an api for interacting
with the listener movie so that sites wishing to embed our
technology could handle certain events. I realize of course that
interframe communication between frames at different domains is a
violation of the same domain rule at the heart of most browser
security. So, I wouldn't be surprised if it isn't possible. And
yet, I could communicate between flash player and the listener so I
still wonder at the possibility.
Does anybody know if what I'm attempting is even possible?
And if so, any clues as to what may be the problem? If anybody
chooses to help with the problem or innovate a work around I would
be happy to share the source files I've been playing with, which
are simple bare bones swfs.

"> One more question along this topic of advanced usage
> of LocalConnections ... is there a reccomended method
> of dealing with multiple windows being open with the
> same reciever movie so that the sender movies aren't all
> sending back to the originally opened movie?
What about sending an arbitrary id as one of the parameters
with your
message? All movies listen, but when a message comes, each
movie checks to
see if the id param matches a correlating id of its own. This
could be a
variable stored in the root of each listening movie. (Am I
movie "A"? Yes?
Okay, I'll follow these instructions.)"
The problem with the arbitrary id is that I have to send it
somewhere, and I need to know the name of the connection to send it
to, but each connection name must be unique. That is why if you
open a new window messaging goes to the first window, the
connection command in the second window will fail because the name
will aready be taken in window one. And the other movies won't know
that and will all send to the named connection which is still in
window one.
The connect function will fail if a connection already
exist.s So, on the one hand all I have to have is a loop that keeps
trying to connect until it finds a free connection. The problem I
am thinking about is having two movies in the same window, one in
the page displayed, and one in an iframe, as I set up on that demo
page. I'll want the one in the iframe to communicate with the one
in the outer page for validation purposes. If all there is is one
window then that's fine. But if sombody were to hit Ctrl+N in IE
they would get a new browser window with the same page. The problem
is how to make it so that the two movies in each window know to
only communicate with each other in only that window?
My thought is that I can use the incremental connection id
technique in each movie and figure that if the increment is
firstMovie_2 in one movie then it should communicate with
otherMovie_2. What I'm worried about in this scenario though is
what happens if the user is caffienated and hits Ctrl+N five times?
Will the two movies increment correctly for each browser window? Or
will there end up a couple windows with a firstMovie_3 and
secondMovie_2 because things didn't load in a controlled sort of
way?
I think the incremental technique would be fine for if a
window closed because that would free the connection id and the
loop would always start at 0, so if you had five windows opened and
closed the first one and opened a new one, the new window would use
the ids with the _0 increment.
Anyway, its helping me to write this stuff out. I'm going to
implement the incremental id thing and I'll report my findings.
As to looking deep into the technotes and docs. That
http://www.adobe.com/devnet/flash/articles/fplayer8_security_05.html
article was great for the table it has in the middle of it which
outlines what is needed for the various ways you try to connect
movies.
My only other reccomendation is the help docs and Excedrin
since it has both Acetometaphin AND caffeine and both are useful
for trudging through the fine points of the flash docs ;).

A Rman question

You issued the following commands to configure setting in RMAN;
RMAN> CONFIGURE DEVICE TYPE sbt PARALLELISM 1;
RMAN> CONFIGURE DEFAULT DEVICE TYPE TO sbt;
RMAN> CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE sbt TO 2;
RMAN> CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE sbt TO 2;
RMAN> CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 2;
Then you issued the following command to take the backup:
RMAN> BACKUP DATABASE PLUS ARCHIVELOG;
Which statement is true about the execution of the above command?
A - The backup will terminate because the FORMAT clause was not configured for the channel
B- It backs up two copies of data files to tape and disk, and two copies of archived log file on tape
C- It backs up the data files and archived log files to disk, making two copies of each data file and archived log file
D-It backs up the data files and archived log files to tape, making two copies of each data file and archived log file
thx in adv

Are you taking a test right now? ( Cause if you are this is a bad idea, google will bust you )
Very odd question.
# configures one sbt channels for use in RMAN jobs:
RMAN> CONFIGURE DEVICE TYPE sbt PARALLELISM 1;
RMAN> CONFIGURE DEFAULT DEVICE TYPE TO sbt;
# Makes 2 disk copies of each datafile and control file to tape
RMAN> CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE sbt TO 2;
# Makes 2 copies of every archived redo log backup to tape
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE sbt TO 2;
# Makes 2 disk copies of each datafile and control file backup set

Flashback Rman question

We are running Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production. (Linux Red Hat AS 4)
Flashback is setup to use this folder /u01/app/oracle/flash_recovery_area/<DATABASE>
RMAN backups to:
/u01/app/oracle/flash_recovery_area/<DATABASE>/backupset
A Full RMAN backup is performed daily.
RMAN creates folders daily for the backup under /backupset, for example:
2010_06_17
2010_06_18
2010_06_19 (and so on)
The RMAN cleans up old backups by issuing this command:
DELETE noprompt BACKUP COMPLETED BEFORE 'SYSDATE-3' DEVICE TYPE DISK;
This leaves the old folder behind. I can clean these up using the OS but my question is:
"Is there a way to have RMAN clean them up when it deletes the Backup?"
Edited by: mseberg on Jun 21, 2010 2:37 PM

Hi,
You need to remove the folders yourself. RMAN will not remove them for you. Write a script to perform this action.
RMAN is not aware whether the folder is empty or has any contents, it is simply removing the backupsets.

ORACLE RMAN QUESTION

Hi,
We take daily incremental backup and weekly full backup.
Our retention policy is 15 days.
Now I want to store my end of month backup seperately so that I can use it later.
How can I achive this with rman.
Thanks in advance.

the CHANGE KEEP just say you want to keep a backup piece. It does not mean you can do anything with that piece!!!
You must make sure you keep enough backups and archivelogs to restore and recover your database successfully! So in incremental, you need to mark the full for KEEP + the incremental + the latest archivelog...
Be sure you test it yourself, backup is serious, do not rely on my procedure without testing it regularly! Thanks

Hot Backup with RMAN question.

Hi all.
We want to make a full backup with RMAN every night with the db up. Version 9i in archive log mode.
My question is if with the command:
backup database plus archivelog delete input format 'MY_FORMAT_STRING';
will store all the files needed for the recovery in one file or I need to backup some other file or do more actions. The backup will be consistent?
Regards.

By using this command you are only taking the backup
all the database files plus all the archived logs
needed for point on recovery.
But still you will have to take the backup of Control
file and parameter files. Which you do by configuringi think its not
RMAN> configure controlfile autobackup off

11i Advanced Pricing Questions on usage of Item Category Segment Values

Hi All,
we are on 11i, i am trying to setup on modifiers using Item Categories. Customer has 4 segment category structure.
Category structure= Vendor, Group, Style, Price code , here is how Data looks = 060.10.800.40
In 11i, can we setup Modifiers on Segment1 & Segment 2 ( 060.10), so system picks up all values for segment3 and segment4.
I understand R12 can do this as per Metalink Note: 746020.1. is this supported in 11i.? I am unable to accomplish this.
regards
girish

Hi
Please donot post more questions in a single thread. If you post it separately, you will get many responses and detailed explanations from more members.
Regarding your queries.,
1. Relevant for delivery field in Item Category is for TEXT Items and for others you should configure the field in Schedule lines.
3. Shipping conditions will be defaulted from the CMR of SP. If a value exists in the sales document type (eg. OR) then it will have priority and will replace the value defaulted from CMR.
5. The pricing applies to Item Level only. But you cannot determine different procedures for different line items.
6. Header conditions will not have access sequence and you cannot create condition records for header conditions in VK11.
7. In consignment process - the first two steps are mandatory i.e., Consignment fillup and consignment issue.
The other two steps are required only if there are returns from the customer(not consignee) and if there are any unsold stocks at the consignee.
Thanks,
Ravi

Advanced Network Question - SSH tunneling through time capsule

Hi!
I have a small question. I just got a time capsule the other day and things are working great with it. At home, internet speeds are what they should be and everything is fine. I replaced it with a linksys, which I consistently got 6.5/1 up. After replacing it, I'm now getting 7.5 down/1mbps up, which is what I am subscribed to.
I used to ssh into my linux box and tunnel web traffic over SSH so when I'm on the road, other's can't sniff my traffic. Basically, I setup firefox to use a socks server, then ssh into home with a dynamic port mapping.
On the linksys (wrt54g), this worked great, and the speeds were acceptable (about 1mbps down/1mbps up). However, after switching the linksys with the time capsule, it seems like the speeds have slowed down tremendously. I'm now getting about 200k down and 1 mbps up when I ssh and tunnel web traffic through my home.
I know that this isn't anything people normally do, but it works great and prevents people from spying on my web traffic when I'm away from home. I was just wondering if anybody has any ideas on why it might be slower now that I replaced it with the time capsule.
Thanks!

Remedial rman question - how to connect to db

Hi.
I need to start making some tests with rman, with the hope of maybe next year presenting it as an option for our data managment here.
First, I need to connect to my test database, but Im already having some problems:
I am following the documentation (version 9.2) "Connecting to Databases with rman".
Chapter 2 explains:to start rman do this :
rman TARGET SYS / oracle@trgt NOCATALOG
I dont want to use a catalog. I have been reading the rman concepts for weeks and Im quite happy with them. Just having practical probs!
Any help please?
