Recently we have a weird thing happens in our Oracle Queries to the views return "ORA-00942: table or view does not exist" unless there are a where clause
select * from VIEW1 failed
select * from VIEW1 where 1 = 1 works
What happening? and how we can fix it?
I am the only DBA in my company and Oracle just crashed on me. The data is corrupted as well as the data on my backup! Is there ANY way I can get the information back?

I have an application that writes blobs via pro*c. It is running at several sites without errors for a few years now. One of the newer sites has started reporting "ora-01578 ORACLE data block corrupted".
I've tried using rman backup validate - it does not report any errors.
I've tried using rman restore and recover to correct the problem.
I've tried deleting the file with the corrupt block and using rman restore and recover to recreate it.
In any of the above cases, I do not see any errors being encountered, and when I restart the application, it works for a while and then starts reporting "ora-01578 ORACLE data block corrupted".
I've had the client do a physical check of the disk and it indicated the media was okay.
We've failed over to the standby system, so I have a wee bit of breathing room - but I'm going to be away for 4 days and will have to get back on this when I get back. I'm a little puzzled that I can fix it for a short while and then it breaks again.

I am having 3 oracle database instances running on 3 seperate Linux Node(RHEL Node).
Instance -1 named - DS

Among of these 3 nodes, we are facing Block Corruption issues with sysaux tablespace.Error in Instance name DS is
Errors in file /u01/home/dba/oracle/diag/rdbms/ds4db/DS/trace/DS_j000_655388.trc (incident=300847):

for this I googled and found some solution as oracle doc [430230.1] related to sysaux couruption.After this again we are facing the same issue in sysaux tablespace.
What i have to do for this error:

I have an application written in Pl SQL Oracle which suppose to send email using utl_smtp. For users that are using Exchange Server 2010 Windows the hyperlinks inside the email are correctly but for users that have a Postfix version installed on a Debian 5 Linux mail server the hyperlinks contains some extra spaces. I think that the CRLF that I'm using inside my code to create the MIME message is not ok interpreted.

1. One day we found some packages got invalid & not compiling at all with error – ORA-00600: internal error code, arguments: [4097], [], [], [], [], [], [], [].
2. Then we successfully restored the database from old RMAN backup of previous date that caused this error.
3. After 2 days again we found the same error in alert_prd log - ORA-00600: internal error code, arguments: [ORA-00600: internal error code, arguments: [4097], [], [], [], [], [], [], [] ORA-06512: at "SYS.DBMS_STATS", line 19089 ], [], [], [], [], [], [], []
4. Then for testing we exported database using exp command & found 3 tables are not exporting because of data block corruption issue.
5. Then we truncated the data from all 3 tables and then able to export successfully.
6. After all this we manually run SYS.DMS_STATS job but found same error logged in prd_alert log.
This looks like, still database block corruption issue is there & we are unable to cure it 100% This is a production system & in very critical state now.
recreate paramater file if you lost init.ora or spfile.ora
STEPS
SQL> startup
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file 'D:ORACLEORA92DATABASEINITGPT2.ORA'
How to resolve ORA-01078 with LRM-00109 error?
For resolving these error, you should need to replace init.ora or spfile if you have backup of same files. If you don't have backup then go to alert.log and copy all parameters in one file and save as "init.ora". Modify same init.ora with some parameters which need single quotation mark " ' " like background_dump_dest,controlfiles,db_name and "dispatchers ......)". Connect as sysdba in SQL*Plus and execute command "create spfile from pfile=" or startup pfile or startup.

View 0 Replies View RelatedBut i do a lot of work-arounds to make sure the installation does not make corrupt my OracleAgent,OracleService and OracleDataGatherer. If i just let the installation do its thing i have problems with my libraries, and can't start anything.
The errors are : Procedure entry point 'BlaBla' could not be located in the Dynamic Link library 'AnyName'.
I notice that i have 2 versions of the libraries in OracleHomeBIN (one version 8, one version 11). The programs that start the OracleAgent,Service and DataGatherer call the old libraries but expect to find values that can be found only in new libraries.
I have a requirement to put together a Oracle SQL template to create re-usable DDL/DML Scripts for Oracle databases.Only the Oracle DBA will be running the scripts so permissions is not an issue.
The workflow for any DDL is as follows:-
1) New Table
a. Check if the table exists from the system/admin views.
b. If table exists then give message "Table Exists"
c. If table does not exist then execute DDL code
2) Add Column
a. Check if Column exists for a given table from system/admin views
b. If column exists in the specified table,
b1. backup table.
b2. alter table to make changes to the column
b3. verify data or execute dml script convert from backup to the new change.
c. If Column does not exist
c1. backup table
c2. alter table to add column
c3. execute dml to populate column with default value.
The DML scripts are for populating base tables with data required for business operations.
3) Add new row
a. check if row exists by comparing old values of each column with new values to be added for the new record.
b. If exists, give message row exists
c. If not exists, add new record.
4) Update existing record (We have createtime columns in these tables so changes can be tracked)
a. check if row exists using primary key.
b. If exists,
b1. deactivate the record using the "active" column of the table
b2. Add new record with the changes required.
c. If does not exist, add new record with the changes required.
