Problem with DATAFILE

Hi Guru!
In my RAC Database I added a Datafile.The location of new created datafile is Local Drive which is different with other Datafiles of Existing Database.After some transactions I was getting a error ORA-01157.Then I made the new created datafile offiline and was getting error like datafile is offline bring it online.Then I dropped the datafile. after that I am getting the status of this datafile is RECOVER.Now I can up the database to MOUNT mode cannot open/startup..
Please help me
Thanks in Advance

Datafiles need to be on a shared location with RAC. There is no exception. Even tablespaces which are exclusively used by a certain instance (undo) need to have the datafiles shared.
If you put the tablespace offline at which you added the datafile on a local location, you can bring up the database. As long as there is no data in the datafile which you added, you can drop the datafile with the command: "alter database datafile xxx offline drop"
(replace xxx with '/path/to/datafile')

[RMAN] problem with registering database

Hello, we have RAC environment on two nodes. We created rman catalog database and then registered our database with REGISTER DATABASE command. After that we issued command SHOW ALL and encountered an error:

Tp ended with error code 0247 - addtobuffer has problems with data- and/or

Hello Experts,
If you give some idea, it will be greatly appreciated.
This transported issue started coming after power outage, sap system went hard shutdown.
Then we brought up the system. Before that , we do not have this transport issue.
our TMS landscape is
DEV QA-PRD
SED-SEQSEP
DEV is having the TMS domain controller.
FYI:
*At OS level, when we do scp command using root user, it is fine for any TR.
In STMS, while adding TR in SEQ(QA system), we are getting error like this.
Error:

Problem with SQL,udfs & procedures

I have couple of problems with my database. Please suggest solution.
We are basically a web product With a Quite large Database
1. I am using functions both User Defined and Built in Functions in
SQL Statement. I want to optimize the query how do i do it.
why the usage of function in sql statements suppresses,the
usage of indexes internally. How to forceable make use of
the index even though function is used.
2. Whenver The Client makes a request to the Database server with a
Sql Query What are the steps we can take at the
client side to enhance the performance of the Query.
(i.e the Data Request ). How to optimize the usage of CPU at
client site?
3. what is the increase in the performance ration by having
separate table spaces for user data,system data and indexes.
4. Why the procedures are getting invalided
after some time. The procedure is
not getting executed at the front end.
Once the procedure is getting invalidated.
However even though the status of the
procedure is invalid the same is getting
executed at the back end.
Can anybody help me
Request for reply ASAP.
Regards
Koshal

1. In Oracle 8i, one can create function-based indexes, where instead of indexing a column, one can index upper() of that column.
2. Optimizing client performance is trickier. One can tune the queries being
submitted by the client, but if getting the first row back -- which is how response time is generally perceived -- set the OPTIMIZER_MODE parameter in init.ora to FIRST_ROWS.
3. There is minimal benefit to having data, index, rollback, and temp tablespaces all separated unless all the datafiles for each tablespace reside on different disks (data on disk 1, index on disk 2, etc). It's recommended regardless, but unless the files are on separate volumes, there won't be a great performance benefit.
4. A procedure is invalidated whenever DDL is issued against any object that that procedure depends upon. For example, if you add a column to a table, any procedures which reference that table will be invalidated. Any procedures which reference views which reference that table will be invalidated, because the view will be invalidated. It's best to run a compile script which looks for and attempts to recompile any invalid objects on a daily basis.

Problem with the cache hit ratio

Hello,
I ma having a problem with the cache hit ratio I am geting. I am sure, 100% sure, that something has got to be wrong with the cache hit ratio I am fetching!
1) I will post the code that I am using to retrieve the cache hit ratio. I've seen about a thousand different equations, all equivalent in the end.
In oracle cache hit ratio seems to be:
cache hits / cache lookups,
where cache hits <=> logica IO - physical reads
cache lookups <=> logical IO
Now some people use the session logical Reads stat, from teh view v$sysstat; others use db block gets + db consistent gets; whatever. At the end of the day its all the same, and this is what i Use:
SELECT (P1.value + P2.value - P3.value) AS CACHE_HITS, (P1.value + P2.value) AS CACHE_LOOKUPS, P4.value AS MAX_BUFFS_SIZEB
FROM v$sysstat P1, v$sysstat P2, v$sysstat P3, V$PARAMETER P4
WHERE
P1.name = 'db block gets' AND
P2.name = 'consistent gets' AND
P3.name = 'physical reads' AND
P4.name = 'sga_max_size'
2) The problem:
The cache hit ratio I am retrieving cannot be correct. In this case i was benchamarking a HUGELY inneficient query, consisting of the Union of 5 Projections over the same source table, and Oracle is configured with a relatively small SGA of 300 MB. They query plan is awful, the database will read the source database table 5 times.
And I can see in the physical data statistics of the source tablespace, that total Bytes read is aproximatly 5 times the size of the text file that I used to bulk load data into the databse.
Some of the relevant stats, wait events:
db file scattered read     1129,93 seconds
Elapsed time: 1311,9 seconds
CPU time: 179,84
SGA max Size: 314572800 Bytes
And total bytes read: 77771964416 B (aproximatly 72 Gga bytes)
the source txt loaded to the database was aprox 16 G
Number of reads was like 4.5 times the source datafile.
I would say this, given the difference between CPU time and Elapsed Time, it is clear that the query spent almost all of its time doin DB file scattered reads. How is it possible that i get the following cache hit ratio:
Cache hit Ratio: 0,92
Cache hits: 109680186
Cache lookups: 119173819
I mean only 8% of that Logical I/O corresponded to physical I/O? It is just not possible.
3) Procedure of taking stats:
Now to retrieve these stats I snapshot the system 2 times. One before the query, one after the query.
But: this is not done in a single session. In total 3 sessions are created. One session two retrieve the stats before the query, one session to run the query, a last session to snapshot after the query.
Could the problem, assuming there is one, be related to this:
"The V$SESSTAT view contains statistics on a per-session basis and is only valid for the session currently connected. When a session disconnects all statistics for the session are updated in V$SYSSTAT. The values for the statistics are cleared until the next session uses them."
What does this paragraph mean. Does it mean that the v$sysstat only shows you the stats of the last session that closed? Or does it mean thtat v$sysstat is increamented with the statistics of each v$sessionstat once a session terminates? If so, then my procedure for gathering those stats should be correct.
Can anyone help me sort out the origin of such a high cache hit ratio, with so much I/O being done?

Because another problem has come up and, right now, i cannot inform myself to be able to comprehend it all.Well, could it be that you need to understand the database you are working on in order to comprehend it? That is why we strongly advise you to read the concepts manual first, you need to understand the architecture that Oracle uses, as well as the basic concepts of how oracle does locking and maintains read consistency. It does these different than other database engines, and some things become nonsense if looked at from the viewpoint of a single user.

It would be useful to see the execution plan jhust in case you have simplified the problem so much that a critical detail is missing.
First, the query code:
2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:>SQL> CREATE TABLE FAVFRIEND
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 2 NOLOGGING TABLESPACE TARGET
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 3 AS
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 4 SELECT ID as USRID, FAVF1 as FAVF FROM PROFILE
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 5 UNION ALL
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 6 SELECT ID as USRID, FAVF2 AS FAVF FROM PROFILE
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 7 UNION ALL
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 8 SELECT ID as USRID, FAVF3 AS FAVF FROM PROFILE
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 9 UNION ALL
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 10 SELECT ID as USRID, FAVF4 AS FAVF FROM PROFILE
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 11 UNION ALL
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 12 SELECT ID as USRID, FAVF5 AS FAVF FROM PROFILE
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 13 ;
Now, Althought it is clear from the query that the statement is executed with the NOLOGGiNG, i have disabled the logging entirely for the tablespace.There are certain rules about nologging that may not be obvious. Again, this derives from the basic Oracle architecture, and if you use the wrong definitions of things like logging, you will be led down the primrose path to confusion.
>
Futhermore, yes, the RDBMS is a test RDBMS... I have droped the database a few times... And I am constantly deleting an re-inserting data into the source database table named PROFILE.>
I also make sure do check all the datafile statistics, and for this query the amount of RedoLog, Undo "Log", Templife used is negligible, practically zero.Create table is DDL, which has implied commits before and afterwards. There is a lot going on, some of it dependent on the volume of data returned. The Oracle database writer writes things out when it feels like it, there are situations where it might just leave it in memory for a while. With nologging, Oracle may not care that you can't perform recovery if it is interrupted. So you might want to look into statspack or EM to tell you what is going on, the datafile statistics may not be all that informative for this case.
>
Most of the I/O is reading, a few of the I/O is writing.
My idea is not to optimize this query, it is to understand how it performs. Well, have you read the Concepts manual?
I have other implementations to test, namely I having trouble with one of them.
Furthermore, I doubt the query Plan Oracle is using actually involves tablescans (as I I'd like it to do); because in the Wait Events, most of the wait time for this query is spent doing "db file scattered read". And I think this is different from a tablescan.Please look up the definition of [db file scattered read|http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/instance_tune.htm#sthref703].
>
Do you really have to use sessions external to the query session ? Can you query v$mystat joined to v$statname from the session itself.
No, I don't want to that!
I avoid as much as possible having the code I execute being implemented in java. Why do you think java has anything to do with this? In your session, desc v$mystat and v$statname, these are views you can look at.
When i can avoid it I don't query the database directly through JDBC, i use the RDBMS command line client, which is supposed to be very robust. Er, is that sqlplus?
So yes, I only connect to the database with JDBC... in very last session.
Of course, I Could Have put both the gather stats before query and gathers stats after query a single script: the script that would be also runing the query.
But that would cause me a number of problems, namely some of the SQL i build has to be implemented dynamically. And I don't want to be replicating the snapshoting code into every query script I make. This way I have one sql with the snapshoting scripts; and multiple scripts for running each query. I avoid code replication in this manner.Instrumentation is a large subject; dynamic sql generation is something to be avoided if possible. Remember, Oracle is written with the idea that many people are going to be sharing code and the database, so it is optimized in that way. For SQL parsing in particular, if every SQL is different, you get a performance problem called "hard parsing." You can (and generally should, and sometimes can't avoid) use bind variables so that Oracle doesn't need to hard parse every SQL. In fact, this is one of those things that applies to other engines besides Oracle. I would recommend you read Tom Kyte's books, he explains what is going on in detail, including in some places the non-Oracle viewpoint.
>
Furthermore, Since the database is not a production database, it is there so I can do my tests. I don't have to be concerned with what other sessions may be doing to my system. There are only the sessions I control.No, there are sessions Oracle controls. If you are on unix, you can easily see this, but there are ways to see it on Windows, too. In some cases, your own sessions can affect themselves.
>
then what it the array fetch size ? If the array fetch size is large enough the number of block visits would be similar to the number of physical block reads.
I don't know what the arraysize you mention is. i have not touched that parameter. So whatever it is, it's the default.You should find out! You can go to http://tahiti.oracle.com and type array fetch size into the search box. You can also go to http://asktom.oracle.com and do the same thing, with some more interesting detail.
>
By the way, I don't get the query results into my client, the query results are dumped into a target output table.
So, if the arraysize has something to do with the number of rows that Oracle is returning the client in each step... I think it doesn't matter.You may hear this phrase a lot:
"It depends."
>
As for the query plan, If i am not mistaken you can't get get query plans for queries that are: create table as select.What?
JG@TTST> explain plan for create table jjj as select * from product_master;
Explained.
JG@TTST> select count(*) from plan_table;
COUNT(*)
         3
I can however commit the create table part and just call for the evalution of the Select part of the query; i believe it should be same.
"Optimizer"     "Cost"     "Cardinality"     "Bytes"     "Partition Start"     "Partition Stop"     "Partition Id"     "ACCESS PREDICATES"     "FILTER PREDICATES"

This query plan was taken from sql developer, exported to txt, and the PROFILE table here has only 100k tuples.
Right now I am more concerned with testing the MODEL query. Which Oracle doesn't seem to be able any more... but that is a matter for another thread.
Regarding this plan. The Union ALL seems to be more than just a binary Operator... IT seems to be Neray.
The union all on that execution plan seems to be taking as leaf tables 5 99sono.Profile tables, and be making a table scan to them all. So I'd say that the RDBMS should only scan each database block once and not 5 times.
But: It doesn't seem to be so. IT seems like what oracle is doing is scanning completly each the table, and then moving on to next select statement in the UNION ALL. Because given the amount of source table that was read, 5 times greater than the size of the source table. Oracle didn't reuse read blocks.
But this is just my feeling.Your feeling is uninteresting. Telling us what you really hope to accomplish might be more interesting.
Anyway, in terms of consistent gets, how many consistent gets should the RDBMS be doing? 5
One for each table block?It depends.

Problem with RMAN incomplete recovery

Oracle Version: 9i
Operating System: Windows 2000
I have a problem with RMAN incomplete recovery until sequence.
According to my database structure ............
SQL> SELECT GROUP#,SEQUENCE#,THREAD# FROM V$LOG;
GROUP# SEQUENCE# THREAD#
1 14 1
2 13 1
3 12 1
I took the backup of backup of full database using RMAN and i am trying to recover like this:
RUN
ALLOCATE CHANNEL C1 TYPE DISK;
SET UNTIL SEQUENCE 7 THREAD 1;
RESTORE DATABASE;
RECOVER DATABASE;
ALTER DATABASE OPEN RESETLOGS;
BUT i am getting a message saying there is no backup of DATAFILE 1,2,......10 to restore although my database is in archivelog mode and i took a backup.
Yachendra

Please consult v$backup_datafile.
It will tell you when the file was backed up.
RMAN will always search for a datafile backup prior to the logsequence or whatever is limiting the incomplete recovery.
Likely when you made your backup Oracle was already past sequence 7.

RMAN problem with block corruption

Hi
I have problem with the block corruption in one of the database .
here is the error message .

RMAN-05009: Block Media Recovery requires Enterprise Edition
Could some one help me in providing solution for this . we we have standard addition only .
Thanks in advance ...

It appears that there was a NOLOGGING operation on an object that resides in '/db/gist1/data/gist1_gis_nologging_01.dbf' .
NOLOGGING operations, as the name suggests, do generate limited redo log, which makes the objects affected by them non-recoverable.
RMAN Blockrecover, as far as I understand, uses full and archivelog backup to perform the block recovery. Since the archivelog backup does not store any changes related to the NOLOGGING operation, then Blockrecover would not be able to help you even if you were licensed.
You can try to restore the object as of the most recent full backup…

Problem with xy-graph program

HI!
I have a problem with my program. With this program i want to load a datafile and to display the data from the file on the xy-graph. i want to display 1,2,3 or 4 graphs on the xy-graph. The problem is, when i want to display only two graphs and i push the "... laden" button, a popup will open and ask me for the 3rd ord 4th graph, but i want only display two graphs.
The program should display the data, when there is a path added in the path-element (the white,red,blue or grenn one).
The second problem is, when i start the program and push the "...laden" button and no path added, a popup will open and aks me for files, but the popup should not open!
Could somebody help me???

Hi,
The function you're using to open the file is automatically asking for a file name when you call it with an empty path connected to the file path input.
So, if you don't want to get the data when the path is empty, you should not call that function.
I've changed your vi to show you.
Hope it helps,

Problem with exp/imp transport_tablespace=y & CLOBs

All,
I am having a problem with values in a CLOB column when exporting/importing a database using "transport_tablespace" command line option.
Some background:
Origin: 9i Windows
Destination: 10g Windows
Export/import work without warnings. But this SQL command:
SELECT DUMP(CAST(TEXT_VALUE AS VARCHAR(4000)), 1017)
FROM SE_PSOI.SEPROPTEXT
WHERE TEXT_ID = 316161
Gives me from the 9i database:
Typ=1 Len=18 CharacterSet=UTF8: U,n,d,e,r, ,C,o,n,s,t,r,u,c,t,i,o,n
But the following from the 10g database:
Typ=1 Len=54 CharacterSet=UTF8: e5,94,80,e6,b8,80,e6,90,80,e6,94,80,e7,88,80,e2,80,80,e4,8c,80,e6,bc,80,e6,b8,80,e7,8c,80,e7,90,80,e7,88,80,e7,94,80,e6,8c,80,e7,90,80,e6,a4,80,e6,bc,80,e6,b8,80
It appears as if there is some sort of charset issue to me. I've tried working with the environment NLS_LANG value when I export and import (and other text values come through OK - just the CLOB is the problem). After Googling and searching the forums here I am unable to find an answer.
Can someone help me or point me in the right direction?
Regards,
Matthew Lesko

Problem with Outlook (client) 2010/2013 profiles on Exchange 2013

We have recently started migrating to Exchange 2013 and have come across a problem with some of our accounts. This problem exists in both migrated mailboxes and natively created 2013 mailboxes.
basically we have a lot of "shared" accounts. We create a user object in AD, give it a mailbox, then give a security group "Full Access" (and often "send-as") permissions on the account. We then Disable the
account in AD (to prevent directly using the password) and then add/remove group members to manage access. everyone uses their own credentials to get to the account.
For the most part this works fine. Users can access OWA and get to these shared mailboxes, they can also 'add' the mailbox to their Outlook client by going into Account Settings->Properties of the Exchange user->More Settings... ->Advanced Tab->"Open
these additional mailboxes:" and adding the mailbox.
However what has happened is that some users were setting up a separate profile instead of adding a mailbox. (Pretty much these
instructions: )
When this is done an error occurs. :
Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost).
Connecting with a profile set up as yourself first does not clear the error, whenever the shared mailbox folder is selected you get this. The exception is if you go into the account properties and turn off Cached mode. the error then becomes:
Cannot open your default e-mail folders. the file c:\users\[user]\appdata\local\microsoft\outlook\[datafile].ost is not an Outlook datafile (.ost).
Which is weird since migrated accounts had working OST files which were functional prior to migration and outlook creates the new OST for new accounts. This message appears to be a red herring and the problem is still sync access but it throws this
error instead.
In the end is creating a new profile for a mailbox you have Full Access to no longer supported in 2013 or is there something we can do to fix this problem?

Hi AD-Tester,
According to your description and I do an test, however I cannot reproduce the problem.
I want to confirm some points, please help to collect answers for following questions:
1. Check all account or some special user face this problem.
2. Try this command to check Atodiscover, Exchange Web services, Availability service, Offline Address Book services works well:
Get-ClientAccessServer | Test-OutlookWebServices -Identity 'e-mail address'
If it works on OWA, problem may point to outlook client. Please try to re-create a outlook profile for testing.
Note: please make sure set properly setting for Outlook anywhere.
Additional, we can recreate an account and enable-mailbox, then disable in AD and try to login outlook account again.
Best Regards,
Allen Wang

Problems with Mail 3.5 reply to address

I have a Gmail account and about two years ago changed the settings on Gmail to have the Gmail reply-to address be my work email. I was using Apple Mail for my Gmail account with no problems. Then, about a year ago, I decided to keep my accounts separate so I went into Gmail settings and changed the settings so that the reply-to address would be my Gmail address.
Apple Mail continued to keep my work email as the reply-to address. I tried seemingly everything - deleting the account and reinstating it, making sure that preferences in Apple Mail didn't have my work email as the reply-to address, etc. Finally I gave up and started using Thunderbird.
The problem is that I really like Apple Mail. I think the entire program is just superior to anything else. But it still has that problem where I send an email using Gmail, and the reply-to address is my work email. I checked Gmail settings and the reply-to address is set as my Gmail address.
I am using IMAP on GMail, Apple Mail 3.5, and OS X 10.5.6
Can anyone help me with this? It is really aggravating. I have a feeling that it is a problem with the GMail server-Apple Mail communication.
I hope I don't have to create a brand new GMail account.
Thanks for any help.

Problems with second standby database

Hello All,
I have oracle 10gr1. 1 primary db and 2 physical standby and 1 is in the same network with the primary and the other is on a remote network. The primary and the standby on the same network is working perfectly well. My problem is with the remote standby. Some log are not being archived. See output below
SEQUENCE# ARC APP
1755 YES NO
1761 YES NO
1772 YES NO
1774 YES NO
1782 YES NO
1789 YES NO
I get this error RFS[10]: "Possible network disconnect with primary database". I think it has something to do with the network connectivity of my second standby and the master db. What parameters should I tweak to avoid this?
Another thing is arhived logs from seq 1728 were not being applied. I tried manually recovering the archive log from 1728 but it says there is an error in the log. I tried getting the specified archive log from the master db and tried recovering it manually but still the same. How would I solve tjhis problem? Would rebuilding the second standby do the trick? Help needed badly.
Thanks in advanced.

Hi,
About seq 1728, if the archive has been lost or alterred, you'll have to rebuild the standby. At least take a backup of the first standby and restore the datafiles at the second standby.
About network connectivity, are you using DataGuard? If so, did you setup the FAL (Failed Archive Logs) server/client parameters on your standby? You can even set your fal_server as being both the primary and first standby..
You should investigate the network connectivity problem with your network administrator. Check alert log and trace files plus sqlnet logs to see when/where/why the communication with distant site fails sometimes.
HTH,
Yoann.
