develop a Oracle stored function or procedure to confirm a availability of datafile on a specific local directory to be read by Oracle External table. The fine looks like filenameddmmyyyy.csv.
I have create a Oracle directory named data_dir that is mapped with physical directory c: mep
Once it is confirmed that datafile is available the ETL process is started.
I m using UTL_SMTP to send mail using my mail server. could i check the availability of 1st mail server, if not available then could i set alternate mail server.

Is any way to isolate the disk region that is corrupted?
If a disk error exist an an ASM disk group how can i isolate the error from that disk group? It's an alternative different to the VALIDATE DATAFILE command in RMAN?I'm using Oracle 11GR2 on a Linux Box.
I am using Oracle 11g database. The situation is I need to run a batch process a fixed intervals and copy data into my table from a remote database using a DB Link. I have 3 tables,1. Original data Table, 2. Exported data Table, 3. Status table. All the data from the remote database will be loaded into the exported data table. As and when each copying is finished the status table will be updated with 'Y' if export is success and with 'N' if export is unsuccessful. When the exporting is over, then status table is checked, if all the status' is Y then the data from Exported data table will be copied into the Original data table after truncating all the rows of Original data table. If the status is N then the Original data table will be intact.
How to check whether the exporting was success for all the exported data ? what to do if the connection through the DB Link was lost during the exporting?
I have setup of two node (prod-db1, prod-db2) clustered database 11gR2 on windows 2008 R2 server. Everything is working fine at this setup.
My question is: Is there a way to make the Enterprise manager Database control run and be available at both the nodes independently. What I see that even at node 2 (which is prod-db2) the EM-DBControl is (https://prod-db1:1158/em) - which means the agent is running at node 1 (prod-db1) only.
My question is that how to make the EM-DBControl also run separately at prod-db2. My idea is to make the high availability of EM-DBControl (in case Prod-db1 machine is down).
I have a Database of Size approx 150GB. I want to create a standby server(High Availability).
1)If our Primary Database crash, the standy server should instantly start automatically i.e no down time.
2)There should be no data loss.
3)Are Data Guard and Replication similar?
I have few queries regarding standby database.
1)On primary Database Standby Redo log is required for switchover and on standby database Standby Redo log is required for
--Real time Apply
--Maximum protection or Maximum availability
Am I correct?
2)My database is in Maximum Performance mode. I set up following entry on init.ora:
LOG_ARCHIVE_DEST_2='service=standby LGWR ASYNC'. My question is do I need to have STANDBY Redo log file on standby database in order to use LGWR transport (LGWR ASYNC)mode from primary? Without Standby redo log on standby database can it transport redo data from primary to standby using LGWR transport mode (LGWR ASYNC)?
3)I have changed from the "ARCH" attribute to "LGWR" attribute of the LOG_ARCHIVE_DEST_n initialization parameter. But I have not changed the protection mode. I would like to know whether is there any impact in the behavior of the database, if we do not change the mode from "MAXIMUM PERFORMANCE" to "MAXIMUM AVAILABILITY"?
I want to put one check box to check all the check boxes.how can i do this?

I want to prevent strange behaviour for logged in end users. In the application builder one can set the availability of the application. I was thinking of making the application unavailable during the upgrade. Is this possible in a runtime only env? How? Or are there (better) alternatives?

I have a tablespace which has around 32gb space consumed. But if i check the used space then its only 16GB. When i tried to resize the datafile it throws the error
ORA-03297: file contains used data beyond requested RESIZE valueAs per my understanding there are not continous blocks which are there in datafile due to fragmentation may be and there by not able to resize it. If i export the tablespace using datapump and reimport this will release the space.
But i want to know if there are any alternative ways to do the same.
In my Production DB. 5 Datafiles created in same tablespace. Datafile size is of 25GB. Data stored in all Datafile. Data is just 5GB in all datafile. I want to move data from 5 datafiles to single or couple of datafiles.
This is in Oracle 11g.
I have a small problem, i will try to explain it, My tablespaces are Automatically extend datafile when full (AUTOEXTEND). It had checked "autoextend ON" checkbox.
What I need to know is, when happened that autoextend accion(day/hour), is it possible?.
We have quarterly and yearly processes that deletes and updates data for millions of rows crossing different tables. To make room on the file system I would either like to remove empty datafiles (my preference) or coalesce TS to compact the data than remove the empty datafile.
Having said that, any query that can show me if a datafile has any data in it or a query that can show me whether a TS is a good candidate to be coalesced maybe a query with something displaying a percentage as to free and used extents and a YES/NO column whether to be coalesced or not.
Every day we have use different data file for an external table to read from.
filename like this "filenameddmmyyyy"
Every day, I have to change name of datafile in external table script which is not a good way.
I want the automated way for external table to read the latest datafile from specified directory.
Further, there is anyway that we could know that the latest data file is available for external table.
Suppose our database have 100 datafiles and right now rman has completed backup of 64 datafile(from file no 1 to file no 64) and in process of backup of 65 number datafile. In mean time I executed some query and it has changed the file no 55. so now my question whether rman will go and bacup this datafile(datafile no 55) again or it will leave this file as it is?

How datafile is created with 640 file permission by oracle software.(I know for security reasons it is created with 640 permission)
example:
-rw-r----- 1 orasd dba 104865792 Mar 15 01:17 users01.dbf
I want to change the datafile permission as below. how to change the default value of the datafiles permission from (640) to (644) internally while creating the datafile from oracle side.
example:
-rw-r--r-- 1 orasd dba 104865792 Mar 15 01:17 users01.dbf
Today i am facing an error when going to rezise the datafile its fixed size is 19000M abut after truncating all tables it is 112M, but when i am going to resize its datafile to 500M its get me an error ora-03297 file contain used data beyond requested size values.
I have done the same before a week without any error.But this time i got the error
Basic situation is this: Oracle 10g database, good RMAN backup from a few days ago. We lost one datafile due to storage corruption. I restored the datafile from RMAN, no problem, and started to roll forward with our archive logs. Problem: one log is corrupted, can't be read, no other copies of it. We are stuck, cannot roll forward any further. The database is up (all activity suspended for now) -- only this one file is offline. Everything else is fine.
My question: Can i do something similar to "open resetlogs" with just the one datafile? Most of what was in the file was indexes, which can be easily dropped & recreated. But a few extents were data which I want to retain. It's old data and the archive logs subsequent to the one on which we are stuck should be pretty much irrelevant. So if i can 'force' the datafile to open up, i believe we should be OK with the little bit of data that's in there, even if we don't apply the remaining archive logs. If it's not 100% consistent we can live with that.
Datafile name is +DISK_GROUP_1/oratst1/datafile/system.1122.764387443
displayed for the SYSTEM tablespace in dba_data_files.Infact, datafile name starts with +DISK_GROUP_1 for tablesspaces. Where is the reference to +DISK_GROUP_1.
What file name should I use to resize or to add new datafile to a tablespace?
