i have attended an interview there i got a question like--->There are 100 archives generated in standby in that a series of five archives are missing and those are not available in the primary then how will you do.....
I have a problem with my Oracle istance and so far I couldn't fix it, I have and Oracle 11g XE istance running on windows server 2003.A couple of days ago I received the error message "ORA-00257: archiver error".I found tips in this forum and wanted to apply but sqlplus doesn't recognize my SYS user/password. I type the correct password but no chance to log in.
If I try to connect using a client like Toad, I receive the message ORA-12170: TNS:Connect timeout occurred. I checked the firewall rules, but it's ok, moreover I was logging in in the past and any change has been performed on it. I learned it's possible to change SYS password.
If I connect as "/ as sysdba" on sqlplus I read "Connected to an idle istance".In order to connect as "/" I had to update sqlnet.ora and restart the service. The parameter SQLNET.AUTHENTICATION_SERVICES
was set as NONE ad I set as NTS. I should probably have to set it as ALL? I found out the orapwd utility to change SYS password throught password file for remote login as sysdba.
I tried to create that file, and when I ran the command it asked me the SYS password, I typed it and it created the file, so I guess the password I type is correct (I had the question to type it wrong). I didn't go to the next step as I wasn't sure to make the right thing and I don't want to make this issue bigger.
As long as I can't log in as sysdba I can't perform the actions mentioned in tips to fix the error 257, but I'm also wondering if the archive error can have a side effect and deny the action of update the SYS password.
I would like to prevent the deletion of a record based on some column value.
Something like:
IF (COLA value < 10) THEN SHOW ALERT; RECORD IS NOT DELETE ELSE DELETE RECORD AS NORMAL END IF;
I want this to happen even before the record is marked for deletion, but I don't know where to put it. I tried a pre-delete trigger, but it does not work they way I want.
When i opened the form and after querying the records if I press CTL+ Down Arrow the record is deleted.
This is the normal runtime form behavior. When ever pressing CTL+ Down arrow I don't want to delete the record, I tried with KEY-DELREC but it is not happening.
I have a RAC system with DR set-up, this is a test environment and it doesn't have any backup, why DR is required but it exist. Since this is a test a lot or archives gets generated and deleting the archives has become a daily job for this server manually.
I want have a script to delete archive logs which is in non-ASM (i.e. filesystem) after ensuring that the archive log has been applied in standby database. If this can done only by RMAN.
We had an escalation wherein one of team members accidentally deleted an LDAP entry for a database. We use Oracle Net Manager to add/delete the connect descriptor.
Are there any logs using which we can find out as to who deleted the entry.
I am facing Deadlock issue in my transaction when record is been deleted in the same table in parallel from a PLSQL package. The package is been called from the Java code.The example and the table structure is given below.
Col1 of tab1 is foreign key to col1 of tab2. Commit will not be done until all the below dml scripts are executed in both environment.
1st session:
Delete from tab1 where col1=1001; Delete from tab2 where col1=2001;
Result: Deletion successful
2nd session:
Delete from tab1 where col1=1002; Delete from tab2 where col1=2002;
Result: Deletion successful
1st session:
Delete from tab1 where col1=1003; Delete from tab2 where col1=2003;
Result: Deletion successful
2nd session:
Delete from tab1 where col1=1004; Delete from tab2 where col1=2004;
Result: Query is executing for a longer time.
1st session:
Delete from tab1 where col1=1003; Delete from tab2 where col1=2003;
Result: Query is not executed and throws Deadlock in the back end.
I have a doubt in RMAN. The scenario is: We take online backup on all days and offline backup on Sunday only. My question is do i need to copy the archives also in offline backup?
What happens when i shutdown the database (the database is in archivelog mode) and alter the database to be in noarchivelog and open the database to do offline backup.
I was carrying out an experiment in order to crash the database and recover it.
The database was running, I moved the control file to another location and to my surprise the database was still running. I tried issuing checkpoint and transaction but it didn't affect database operations. I tried doing log switch. It completed successfully. According to my understanding and Oracle Certification books database was supposed to crash. But it didn't.
I tried this not only on RHEL, Windows XP but also in Solaris 5.10. The database version is Oracle 10.2.0.4 Standard Edition.
Maybe you can tell me if you think it's right or wrong for Oracle to behave like that. What basically happened is that I've set up a trigger to capture deleted rows from testtab into testtab_del.
I have inserted and immediately after - deleted a row from testtab. Then I inserted another row, committed, and checked my testtab_del table.
I've seen that val1 was inserted and committed into testtab_del. This happened in spite of the fact that this row never existed as a *committed row*.
What do you think about this behavior in this scenario? Works as designed or not?
SQL> show user USER is "ANDREY" SQL> col tcol for a10 SQL> drop table testtab;
If as part of housekeeping of the Source database we delete some records (older records), will the materialized view also be updated with the deletion? I believe the answer is yes. In that case can we ensure that this delete does not happen?
Is there anyway we can prevent MView refresh from deleting the records that is once inserted even if we delete the same records in source DB?
I'm on a Windows server 2003 R2 64 bit, database is 11.1.0.7. From RMAN connected to the target and the catalog, this is a show all;
RMAN> show all;
RMAN configuration parameters for database with db_unique_name ORCL are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 3 DAYS; CONFIGURE BACKUP OPTIMIZATION OFF; CONFIGURE DEFAULT DEVICE TYPE TO DISK; CONFIGURE CONTROLFILE AUTOBACKUP ON; CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'F:oracleadmin
[code]....
I'm running incremental backups, a level 0 on sunday and a level 1 the other days of the week, this is the ctl file:
LEVEL 0: connect target /@ORCL connect catalog rman/rmanpw@rmancat RUN {
[code]....
The level 0 does delete the archive logs (because of the delete input). Each backupset has two copies of the archive logs (which is what I want), and I expected the logs to be deleted after being backed up 2 days (each day is twice, 2 days = 4 times). But it's not deleting the logs, even after 6 runs.
I have a DR setup with the following configuration
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 30 DAYS; CONFIGURE BACKUP OPTIMIZATION OFF; # default CONFIGURE DEFAULT DEVICE TYPE TO DISK; CONFIGURE CONTROLFILE AUTOBACKUP ON; CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default CONFIGURE MAXSETSIZE TO UNLIMITED; # default CONFIGURE ENCRYPTION FOR DATABASE OFF; # default CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE ; # default CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY
I dont want to backup the STDBY DB but I want the ARC files to be removed when applied so my flash area does not fill up. Is there some command(rman or not) that can fire off this policy?
1.Is it necessary to reorganize a table and index after the deletion of records from table ? Because i see some change in table size after table and index reorganization.
2.Will re org table and index improve the database performance ?
