RAC & Failsafe :: Archive Logs Are Missing In Hot Backup

Dec 9, 2012

We are using the following commands to take hot backup of our RAC database. Hot backup is fired by "backup" user on Linux system.

=======================
rman target / nocatalog <<EOF
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '$backup_dir/$date/%F';
run {
allocate channel oem_backup_disk1 type disk format '$backup_dir/$date/%U';
#--Switch archive logs for all threads
[code]......
=======================
Due to which after command (used 2 times) "sql 'alter system archive log current';" I see the following lines in alert log 2 times. Because of this all the online logs are not getting archived (Missing 2 logs per day), the backup taken is unusable when restoring. I am worried about this. I there any to avoid this situation.
=======================
Errors in file /u01/oracle/admin/rac/udump/rac1_ora_3546.trc:
ORA-19504: failed to create file "+DATA/rac/1_32309_632680691.dbf"

Apr 23, 2013

While Configuring Data Guard for ORacle 10g (10.2.0.4) 64 bits on Windows 2007 Server 64 bits.I got few questions

1. What is the Default mode of Standby Database?

2. Should we Always Start Physical Standby Database to Recover Missing Redo Archive Log?

SQL> startup mount;
ORACLE instance started.

Total System Global Area 591396864 bytes
Fixed Size 2067496 bytes
Variable Size 163578840 bytes
Database Buffers 419430400 bytes
Redo Buffers 6320128 bytes
Database mounted.

SQL> alter database recover managed standby database disconnect from session;
Database altered.

3. When there are missing Redo Log Archives e.g.

----On Standby Database--------

SQL> SELECT RESETLOGS_ID,SEQUENCE#,STATUS,ARCHIVED FROM V$ARCHIVED_LOG
2 ORDER BY RESETLOGS_ID,SEQUENCE#;

RESETLOGS_ID SEQUENCE# S ARC
------------ ---------- - ---
812980008 15 A YES
812980008 16 A YES
812980008 17 A YES
812980008 18 A YES
[code]....

65 rows selected. Log 8, 9, 10, 11, 12, 13, 14, 15 are missing.

SQL & PL/SQL :: Archive Logs Filtering

Mar 3, 2011

I am using Oracle 11.2.1.0 version.I want to restrict archiving for some tables. I think NOLOGGING will solve this problem. Is there any option for restricting archiving.

For example, I have three tables called A, B and C. I want to archive only 2 tables A and B but not C.

RMAN / TSM - Missing Arch Logs Backups?

Aug 26, 2013

I have an environment in which backup is performed of Oracle 10/11 databases with the use of RMAN and Tivoli Storage Manager (Data Protection for Oracle).There are several databases and for every one there is a daily full backup and hourly archive logs backup.

Sometimes when full db backup takes longer (up to 4 hours) archive logs backups are missed - as TSM node cannot perform two backups at a time. I would like not to have those missed backups.

Option A was to delete association of the arch log scheduler during full backup. But when removing association we lose historical data about backup. And we need historical data to be able to create weekly / monthly / quarterly statistics of completed backups. We need to have 99% completed.

Option B was to create two nodes in TSM (TDPO) and one will do full backup only and another one only arch logs backup. So the problem is moved to RMAN. But from RMAN specialist I heard that this may cause problems with full backup. During full backup also archive logs are backed up (at the start and end) so there might be a problem with accessing the file that is used by another process. And this may cause problem with full backup - which we want to avoid especially.

Real Application Clusters :: Using FRA For Archive Logs?

Jan 21, 2013

Trying to find a best practices document from Oracle regarding the use of ASM to store the archivelogs in RAC. Most of the DBA's I know create a non-ASM location to store the archivelogs. Are there any considerations if you are also using dataguard?

How To Capture TXs From Archive Logs To Replay On 10g Database

Feb 12, 2013

I am looking for a way to capture a TXs from one database and create a script or use it with tool, so we can capture TXs close to production while testing changes being implemented in database.

Env:

OS: Redhat Linux 5.0
DB: 10.2.0.4

Actually Requirement: We have active-active Golden Gate setup done for one of our DB and once a quarter we make changes in the database using DDL (CREATE / ALTER - TABLES, FUNCTIONS, TRIGGERS, etc). We are 24/7 environment and hence no downtime is affordable. What I like to know is a way to capture all TXs from one of the DB and create a script so we can run them while we are testing new changes in the database. Something like DBMS_WORKLOAD_CAPTURE Package (Available only after 11gR1) or some tools available in the market.

I also tried looking into Load Runner but felt it works with App tier than DB, I may be wrong there.

Data Guard :: Archive Logs Are Being Shipped But Not Applied

Jun 27, 2013

Currently I am at the point where the configuration has been completed, and I just need to sync the standby database to the primary one. I can see in the log files that the archive logs are being shipped, but they are not applied on the standby system. 

If I run "recover standby database;" manually in sqlplus I can see that it is trying to apply an archive log which is way too old (ORA-00279: change 9656498443 generated at 04/29/2008 08:45:08 needed for thread 1). I

n the alert log I can also see this error: Warning: Recovery target destination is in a sibling branch of the controlfile checkpoint. Recovery will only recover changes to datafiles. 

At this point I was thinking that the standby database might be on a different incarnation compared to the primary, but this is not the case, they are both in incarnation 6:6  6  MVF  4023175798 CURRENT 48493546257 13-06-21

Backup & Recovery :: RMAN Hot Backup Plus Archive Log Files?

Jan 11, 2008

I had a production db with archive logging enabled

SQL> select name,status
2 from v$archived_log;

NAME STATUS
---------------------------------------- -
D:ORACLEARCHIVE_ORCL11_13.DBF A
D:ORACLEARCHIVE_ORCL11_14.DBF A
D:ORACLEARCHIVE_ORCL11_15.DBF A

[code]...

So i need to restore archivelogs by using sequence

RMAN>RESTORE ARCHIVELOG FROM SEQUENCE 20 UNTIL SEQUENCE 28;
So the restore is completed successfully
So its very hard to monitor archivelog files
i feel i should have included all archivelog files while taking RMAN backup

RMAN >backup database plus archivelog all delete input;

but the problem is my RMAN backup is already 360GB in size and it takes 4-5 hrs to complete .so i need to schedule RMAN backup at one time (e.g sunday) ,delete the archivelog files older than sundayand now schedule the archivelog backup at another day (e.g wed &sat)

my question is where i have to change my script to backup all avaialbe archivelog files if old archivelog files are deleted at os level?

RMAN> run {
2> allocate channel c1 type disk;
3> sql 'alter system archive log current';
4> backup archivelog all format 'D:oracleackuplog_t%t_s%s_p%p' delete input;
5> release channel c1;

RMAN Backup Without Archived Logs?

Jul 28, 2013

Assuming you have a 9i database . where you have it enabled in archive mode , yet constantly deleting the archived redo logs , due to space constraints .

Will you be able to perform a full level 0 backup , and the following incremental backups , in the absence of the archived redo logs ? And are these incremental backups enough to recover the database or particular data files , to the point of the backup itself at least ?

RMAN :: Does Cold Backup Must Have Archived Redo Logs

Jul 25, 2012

URL....I'm practicing for the OCP test and one of the questions is that there is a backup from yesterday and the last archived logs are from the day before yesterday not mentioned if it's cold or hot backup.

If its a cold backup - cant we recover it? is it a must to have the archived redo logs also when recovering a cold backup? That sounds not logical since those logs are made only for a hot backup. URL.....
