what is the meaning of 'SBT_TAPE' in the following command in RMAN? In the following command, does it refer to a tape drive, or a hard disk backup?
allocate channel t1 type 'SBT_TAPE' parms 'ENV=(NSR_SERVER=<a backup server server name>,NSR_CLIENT=<a oracle server>,NSR_DATA_VOLUME_POOL=ORACLE ARCHIVE LOG)';
it is necessary to allocate channel for rman back up and during rman back up what should be the state of target database me script for configuration and incremental level 1 daily back up script
and normal oracle secure incremental level bacl up script back up should be done daily
I have on PC running Windows Server 2003 named "Host A" and another Windows Server 2003 named "Host B".I made a Backup from Host A and want to restore this on Host B with following procedure.
Prepare & Backup: SQLPLUS SYS AS SYSDBA SQL>SHUTDOWN IMMEDIATE SQL>STARTUP MOUNT SQL>ALTER DATABASE ARCHIVELOG; SQL>ALTER DATABASE OPEN; SQL>ARCHIVE LOG LIST; SQL>ALTER SYSTEM ARCHIVE LOG START; SQL>QUIT [code]...
But when i now try to access the Database Control i got following Error:„503 Service Unavailable: Servlet error an exception occurred the current application deployment descriptor do not allow for including it in this response" and the restored Datas are not included.
whats the difference between channel and parallelism in RMAN ?
What is the Oracle recommendation for RMAN channel allocation ? I have read some were that RMAN channel allocation must be 4 times of the Server CPU -1. Say for example if there are 2 cpu in the server, then the channel allocation would be 4 * 2 -1 = 7 ?
while executing a clone script i got the below error : -
RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of restore command at 11/15/2011 20:07:34 RMAN-12010: automatic channel allocation initialization failed RMAN-06758: DB_UNIQUE_NAME is not unique in the recovery catalog
Here i understand that RMAN couldn't find which SPFILE to use to restore the target DB.
How do i check for the DB_UNIQUE_NAME in recovery catalog?
The proposed solution that i found was Use the FOR DB_UNIQUE_NAME option to specify the name of the instance whose parameter file you want to restore. how to implement this in my clone script?
I just made the swich to have my RMAN backup directly to tape and here are the parameters I have set.
CODECONFIGURE DEFAULT DEVICE TYPE TO 'SBT_TAPE'; CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE SBT_TAPE TO '%F'; CONFIGURE DEVICE TYPE 'SBT_TAPE' PARALLELISM 4 BACKUP TYPE TO BACKUPSET; CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE SBT_TAPE TO 1; # default
[code]...
When I do an active clone I need to set my parameters back to the following in order to makeit work.
CODECONFIGURE 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
[code]....
Instead of un-doing my RMAN TAPE settings, is there something I can do in my active clone script to tell it read/write from/to disk instead of tape. I tried allocatiing disk channels but was unable to get my script to work. The only way it worked was to back out all the tape settings and put everything back to disk.
CODErman catalog=rman/rman@prod target=sys/sys@prod << EOT connect auxiliary sys/sys@dev duplicate target database to dev from active database nofilenamecheck pfile=/u01/app/oracle/product/11g/dbs/initdev.ora; exit
We are running oracle 10g on a solaris system. We were taking the backup to the tape system previously. But the tape system is broken due to some reasons and cannot be used now. Now I am trying to take a rman full backup with archivelog to a NFS disk. The server in which the NFS disk lies is in Ubuntu. I have also considered that there is some problem with the NFS rman backup but can be solved by using hard and noac while mounting. Now I wanted to know is, what parameters should be changed to direct the backup sets to the new location in NFS instead of the old disk ? Do I need another media manager as in tape?
Am trying to configure rman to backup to a directory to a linux server on the network. Database is on windows server. Here is the parameter changes
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '\\204.47.240.126\bexdisk\backup\%U' ; new RMAN configuration parameters: CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/oraback/rman/sde_backups/%U'; new RMAN configuration parameters are successfully stored starting full resync of recovery catalog full resync complete
Here is my rman script
ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE DISK; run { crosscheck archivelog all;
[Code]....
instead its backups but to my ORACLE_HOME\database directory..
Accidentally without checking the channel allocation I have given the backup archivelog from sequence until sequence with delete input. This backup piece went to the disk but it should go to Tape.I know that we can catalog this backup piece but I want to move this backup files in disk to Tape using RMAN. Is there anyway or I have to lie with Backup team or OS team for this file movement?
We store the date in String Type format of "MON-YYYY", we require to run the report base on that string contain date column, During the Query execute the Error Display of (ora-01858: a non-numeric character was found where a numeric was expected)
The Query is :
select period_name,doc_sequence_value,doc_sequence_id,date_created,name,JE_SOURCE,XX from ( select period_name,doc_sequence_value,doc_sequence_id,date_created,name,JE_SOURCE,TO_DATE(XX,'DD/MM/RRRR') XX from ( select TO_CHAR(TO_DATE(('01-'||substr(gl.period_name,1,3)||'-'||substr(gl.period_name,5,2)),'DD/MM/RR'),'DD-MON-RRRR') xx,
i have changed date's format and the calendar type in sqlplus through the following command so the date's format and the calender type both changed successfully and work, but in oracle form the they haven't changed.
alter session set nls_calendar='persian';
ALTER SESSION SET NLS_DATE_FORMAT='YYYY/MM/DD';
ALTER SYSTEM SET NLS_DATE_FORMAT='YYYY/MM/DD' SCOPE=SPFILE;
Note: i know session would change the format temporally but i want to change it permanently so i tried alter_system but still no result
We have a Production Oracle 10g R2 RAC on HP-UX v2 IA64 servers.We have Two Disk Groups one for Archive (ARC_DISK - 100 GB) and other for Database(DATA_DISK - 1 TB]. We wanted to add more space to the DATA_DISK disk group.Unix admin configured 200 GB from SAN and changed the ownership of the Disk to oracle and permissions to 775 on 1st Node.I opended DBCA from 1st Node and was able to see the disk in 'Show Candidate'.
I added this disk to the DATA_DISK disk group and clicked OK but got ORA- error with some message like some operations could not be performed. I exited DBCA.We realized that we had forgotten to change the ownerhip and permission from the 2nd Node.Unix admin changed the ownership of the Disk to oracle and permissions to 775 on the 2nd Node.
I opened DBCA again from 1st Node and selected the DATA_DISK disk group but could not find the Disk in 'Show Candiate' open. I clicked on 'Show All' and this disk was shown with Header_Status - MEMBER but not allocated to DATA_DISKGROUP. When I clicked the 'Show Member' option, this disk is not shown for DATA_DISK disk group. I exited DBCA at this point.As this is a critcal Production database I didnt proceed any further and exited DBCA.
Now I need to add this Disk to the DATA_DISK disk group but not sure which option to select. I got one reply from another forum to run DBCA select the DATA_DISK Disk Group and then click 'Show All' and select this Disk (which already has MEMBER as Header Status) and select Force Option and click OK to continue.
I Configured an ASM instance and a disk group with two disk for normal redundancy.
> Here .. each disk is 2gb
The disk group has two disks...
SQL> select group_number, name, type, total_mb, free_mb 2 from v$asm_diskgroup;
GROUP_NUMBER NAME TYPE TOTAL_MB FREE_MB ------------ ------------------------------ ------ ---------- ---------- 1 DATA NORMAL 4000 3898
as the group has two way mirroring (Normal redundancy) How much data (2 GB or 4 GB) can i keep in the disk group? My conception is I can keep 2 GB data in the disk group... (as the disk group keeps every extent in another disk as mirror)
I have 2 servers both having windows server 2008 64 bit as operating system installed on both I need to install oracle clusterware 11g r1 on both servers with clustering on external storage. I have configured the network(private,public and virtual) for both servers and have started the installation.
In the installation of oracle I add both servers but then I reach to a point where they ask me for voting disk or ocr disk in the cluster configuration storage but no disk is present how can i create ocr disk or voting disk on windows server 2008? And the external storage should I buy a special type of storage that supports clustering to continue my work?
