Configuring rman backup for oracle on rac cluster

Hi GURUS
We are buying installation oracle rac on a two node server. We do backup our db using rman and TSM .
Does anyone have any guidance on using TSM scheduled TDP backups with
Oracle RAC multi-node?
More to that, is it possible to have multiple archive log destination?
Any advice would be appreciated.
David

While you can have archives going to different destinations, on different nodes, it is not advisable because if these destinations are not reachable in case of a node/system failure, you have no access to these archive logs.
Actually for easy accesibility it would be better to place the archive logs of all instnaces on shared storage. If you are using ASM and using a FRA disk group, you may want to have your archives go into this location.
NFS mounting filesystems could be slower and may have certain perforamance implications.

RH Linux VIP configuration not working for Oracle 10g RAC installation

Hi all,
I am trying to setup my test cluster on Oracle 10gR2 and Red Hat Linux 4. I have the public and private networks working fine and setup. However, after I setup the two VIP addresses, I cannot even ping these two virtual IPs from Linux. CRS install fails during initial run because it cannot communicate with the two VIP IP addresses. Can anyone help me out as to how to go about fixing the two VIPs so that Linux can ping them and CRS will install?
Thanks

It sounds like you configured your VIP on Linux in advance, before installing Oracle.
You are not supposed to do that.
Decide on an IP that the VIP will use with your network manager, but don't configure it in Linux. So before you start the clusterware install, ifconfig should not show your VIP.
CRS does not need VIP when you install the clusterware, only the interconnect address.
VIP is configured using a utility called VIPCA. If Clusterware installation fails and you think it was caused by VIP issues, try running VIPCA manually and let us know what were the results.

RMAN backup for two databases with similar DBID

We have two databases with SID 'uiivc' and 'uiivc1' running from one of the HP Unix 11.11 PA-RISC server. I did configured RMAN backup for both databases. But it is found that both databases have same DBID [connected to target database: UIIVC (DBID=3005194057) for UIIVC & connected to target database: UIIVC1 (DBID=3005194057) for UIIVC1] and backup configured via crontab seen running fine with full backup at weekend and archivelog backup at daily for both databases. Now my query is that will it create any issues at time of restoration since both databases have similar DBID? Does RMAN uses DBID to distinguish databases?
Kindly help to clarifiy

Hi Tycho,
I configured RMAN to store controlfile backups in different folders on each database.
UIIVC database:
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/hot_backups/rmanbkp/uiivc/cf%F';
UIIVC1 database:
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/hot_backups/rmanbkp/uiivc1/cf%F';

And I saw backups are placing in the respective folders too. So with these settings, can I safely assume there is no issues with RMAN backup and restore having similar DBID for two databases running on same server?

RMAN / backup. oracle 9 vs. oracle 10

My colleague mentioned a while ago that we had to investigate RMAN &/or a backup client, "because in oracle 10, when doing an export of a live db, oracle does not switch into "single user mode" like it did in 9. So we couldn't have 100% faith in our .dmp file."
I'd like to do some further research on this, but looking through the "Oracle 10 Complete reference" and googling - I don't see any information about it. Has anyone here dealt with this or know of a link I should see?
Finally... Does anyone know if an RMAN backup for Oracle 10 accounts for any "in progres" transactions?
Thanks in advance,
Mike.

Oracle, itself, doesn't switch to single user mode.
Your colleague might have been talking of scripts which shutdown and restart the
database in restricted mode to run an export of the database.
RMAN backups as in 8.0/8i/9i/10g (or EBU in Oracle 7) and scripted (aka
"user managed") backups are all physical backups. They take database blocks
"as they are". Conceptually, the datafile backups aren't aware of active transactions.
It is the redo stream in the archivelogs that is required for you to be able to restore
and recreate a consistent database image.

Rman backup for rac by oem

Br,Hi,
DB : 10.2 and 11.2
How to schedule rman backup for cluster in OEM?How to schedule without OEM?
If one of the node failed,Is it possible to run in another node automatcially?
How to schduel export/datadump in rac by oem?
Br,
Raj

I Am not using oem, without oem you should write several scripts....
for linux hot backup(archive log enabled):
bck.sh
set ORACLE_SID=mydb
set ORACLE_HOME=....
rman target sys/.... @'.../bck.ora'
bck.ora
run
BACKUP AS COMPRESSED BACKUPSET FORMAT "..../db_%d_%T_%s_%p_%U.bak" INCREMENTAL LEVEL 0 DATABASE PLUS ARCHIVELOG DELETE INPUT FORMAT "...../archivelogBackup/arch_%d_%T_%s_%p_%U.bak";
delete force noprompt obsolete redundancy 3;
backup FORMAT '..../ctl_%d_%T_%s_%p_%U' current controlfile spfile;
And create executable job which instance_id=1 and will run your bck.sh script and create schedule for this job, when first node will down you must change instance_id attribute to second one, and be sure that all backup paths exists in all nodes.

SCI and RSM for Oracle 9i RAC

Hi gurus,
Could you please confirm if we can configure 2 or more SCI interconnects (for Private Interconnects) on a E15K cluster ?
This is for a High Availability requirement for Oracle 9i RAC. What i need to know is that,
Assume that i have configured 3 SCI Cards on NODE 1 and 3 SCI Cards on NODE 2. Sun Cluster 3.1 is configured on both nodes.
1) If i activate all the cluster interconnects on NODE 1 and NODE 2, will Oracle 9i RAC based traffic flow on all the 3 cards for EACH Node, thereby providing 3 gbps of bandwidth ?
2) What if there is a failure in one of the cards? will the other 2 continue to function, if failover mechanism is configured?
3) Do i need to do something special for Oracle to be enable to recognise that 1 card has failed and it needs to start transfering packets using the other 2 surviving cards?
These questions are assuming that it is an SCI card using RSM protocol.
Will this also be applicable for a Gigabit Ethernet Card running UDP? I have heard that SCI and RSM is a very good combination and just behind the Sun Fireplane interconnects which also uses RSM.
Is that true?
Thanks a lot folks.

Spockaris

Could you please confirm if we can configure 2 or more
SCI interconnects (for Private Interconnects) on a
E15K cluster ?This is being tested now. More below...
This is for a High Availability requirement for Oracle
9i RAC. What i need to know is that,
Assume that i have configured 3 SCI Cards on NODE 1
and 3 SCI Cards on NODE 2. Sun Cluster 3.1 is
configured on both nodes.
1) If i activate all the cluster interconnects on NODE
1 and NODE 2, will Oracle 9i RAC based traffic flow on
all the 3 cards for EACH Node, thereby providing 3
gbps of bandwidth ?Bandwidth does not seem to be a problem for RAC.
Latency is a problem, but adding interconnects won't
solve the latency problem unless bandwidth was also
the problem. I haven't been able to find any customers
who have interconnect bandwidth problems on any
Sun Cluster, let alone RAC. If you know of any, please
let me know.
2) What if there is a failure in one of the cards?
will the other 2 continue to function, if failover
mechanism is configured?Yes, that is how it works today for interconnects.
3) Do i need to do something special for Oracle to be
enable to recognise that 1 card has failed and it
needs to start transfering packets using the other 2
surviving cards?No, under Sun Cluster, this is managed for Oracle.
These questions are assuming that it is an SCI card
using RSM protocol.
Will this also be applicable for a Gigabit Ethernet
Card running UDP? I have heard that SCI and RSM is a
very good combination and just behind the Sun
Fireplane interconnects which also uses RSM.
Is that true?It is true that low latency networks help performance of
RAC clusters. However, there does not seem to be a
direct correlation between interconnect latency and
performance. There are a number of studies completed
and in progress on this topic. We can generally say that
for the same RAC configuration for the same workload,
the lower latency interconnects will perform better. But
beyond that, the problem gets complex quickly and YMMV.

The best option to create a shared storage for Oracle 11gR2 RAC in OEL 5?

Hello,
Could you please tell me the best option to create a shared storage for Oracle 11gR2 RAC in Oracel Enterprise Linux 5? in production environment? And could you help to create shared storage? Because there is no additional step in Oracle installation guide. There are steps for only asm disk creation.
Thank you.

Here are names of partitions and permissions. Partitions which have 146 GB, 438 GB, 438 GB of capacity are my storage. Two of three disks which are 438 GB were configured as RAID 5 and remaining disk was configured as RAID 0. My storage is Dell MD 3000i and connected to nodes through ethernet.

Configuring Web Services for Oracle XML DB

Hi all...
I think I need some help one this subject....
We have a 10G Release 2 Oracle single instance ( not RAC) install on a Linux Redhat v5.3 64 bit server. Are developers are user Visual Studio .Net and wnat to send xml files to a web service so that the xml file (containing data) can call a PL/SQL package (to be written) which will take the data out of the xml input file and insert rows into a prefined table within the instance. Now they have browsed the web and have come upon the following links...
http://docs.oracle.com/cd/B28359_01/appdev.111/b28369/xdb_web_services.htm
http://docs.oracle.com/cd/B28359_01/appdev.111/b28369/xdb22pro.htm#i1026724
Currently, within the database I looked at the schema XDB and have unlocked the account and connected as the user XDB. There are some 680 objects in the following groups...
SQL> select object_type, count(*) from dba_objects where owner='XDB' group by object_type;
OBJECT_TYPE COUNT(*)
SEQUENCE 2
PROCEDURE 5
OPERATOR 8
LOB 334
LIBRARY 12
PACKAGE 20
PACKAGE BODY 17
XML SCHEMA 25
TYPE BODY 5
TRIGGER 12
TABLE 36
INDEX 51
FUNCTION 5
INDEXTYPE 2
VIEW 2
TYPE 144
16 rows selected.
Now in the links above it mentions that the xdbconfig.xml needs to be altered etc. However, I have searched the entire $ORACLE_HOME and there is no file definition of that description.
From a DBA prospective...what do I have to install on the Linux server? I assume from the Oracle Database 10g Companion Products I need to lay down Oracle HTTP Server in a new Oracle home as the first step...or not? Does the HTML DB need to be installed as well?
And for Configuring Web Services for Oracle XML DB...what else has to be installed? And from what product line?
Thanks in Advance....
Cheers
Roegr

Hi Marco...
First of all ...thanks for the reply.
I followed the link and the infor in that web page. However, there were a few things that did not work....
1. The http://localhost:8080/ as is brought up a web page withe the heading as
==========
ORACLE DATABASE 10g EXPRESS EDITION LICENSE AGREEMENT..
==========
The other browser test ftp://localhost:2100/
did not find any page?
2. Then I went onto running (as the sysdba) the pl/sql to enable the ORAWSV Entry Service
however it error out. So I did a describe on DBMS_XDB and the function deleteServlet does not appear
then I had a look and this link to > http://www.liberidu.com/blog/?p=471
was for 11G and the other link > http://docs.oracle.com/cd/B28359_01/appdev.111/b28369.pdf
was for 11G.
However, we are on 10G
=================
SQL> select * from V$version;
BANNER
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi
PL/SQL Release 10.2.0.3.0 - Production
CORE 10.2.0.3.0 Production
TNS for Linux: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - Production
==================
So is there must be other sql for 10G?

Related to Unused compression in RMAN backup for 10.2.0.4 database

Hi
I recently read through one of the document related to Unused compression in RMAN backup for 10.2.0.4 database. According to this
Unused Block Compression is done, if all of the following conditions apply:
+ The COMPATIBLE initialization parameter is set to 10.2
+ There are currently no guaranteed restore points defined for the database
+ The datafile is locally managed
+ The datafile is being backed up to a backup set as part of a full backup or a level 0 incremental backup
+ The backup set is being created on disk.
I have two queries
1) What is meant by "uaranteed restore points defined for the database"
2) If backup is being directly taken to tape, this feature would not be used
Rgds
Harvinder

1. Normal and Garanteed Restore Points
2. No

Rman cold backup for oracle rac

Hi experts;
I want to create a cold backup for an oracle 10g rac DB.
It has 2 nodes, it's not in archive log, this will be the next step.
But now, I want to backup before to proceed.
My doubts are:
I need to shutdown the both nodes?
If yes:
I need to startup nomount just in one node?
If there any document with this specifics steps?
Thanks for your help.
Al

Cold backups are done with the DB completely shut down.
For RAC the data files are used by all nodes in the cluster.
You need to shut down all instances in the RAC.
Then use your OS utilities or RMAN to do the backup.
Here is an 'Ask Tom' topic that discusses this:
http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:851658400346232494

RMAN backup in ORACLE RAC database

Hi there,
We are using RMAN backup strategy for taking backups from one node(eg.node1).Database is RAC database, version 9.2.3. and OS is Solaris 5.10.
this is the configuration which we use, as follows:
Connecting to Prod.Database using catalog database.
rman catalog=rman/rman@CATDB target=sys/oracle@PRODDB(node 2).
RMAN> show all;
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 30;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/rmanback/_%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 5;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/rmanback/CMWPROD_%s.bak';
CONFIGURE CHANNEL 2 DEVICE TYPE DISK CONNECT 'SYS/oracle@PRODDB(node2)';
CONFIGURE MAXSETSIZE TO 7 G;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/oracle/9.2.3/dbs/snapcf_CMWPROD1.f';
As the above config shows RMAN is connecting to PROD DB (node 2). But we need to take backups (datafiles and as well as archive logs) from two nodes (i.e from node 1 and as well as node 2).
Is there any possibility for taking backups from two nodes?
Thanks,
Balu.

RMAN backup and Oracle RAC

Hello,
I am newbie with Oracle RAC 11g.
So, I do the following steps to configure RMAN to back up the Oracle RAC:
- Create a tablespace to RMAN User;
- Create the user rman;
- Connect to catalog (the databsae RAC itself);
- Register the database;
- Create the "complete_backup" script on catalog.
So, when I enter on Enterprise Manager, I can see
the "Availability" tab and the "Recovery Catalog Settings" link.
I setup the user rman that I've created with the host RAC1.
Is this really necessary on EM? The "Backup Setting" on EM
is equals to rman (database user) catalog?
When I go to "Schedule backup", I want to use the "complete_backup" script
that I've created. What the best way to schedule this script
to run each sunday, for example?
Thank you.

Hi,
To perfom a test you can create a new single database (RCVCAT) in one of the hosts that you have.
Create a database without any option with and use minimum of memory (don't use memory_target) set pga (50M) and sga(400M).
Create a user RMAN; with Grant connect,resource,recovery_catalog_owner.
Tablespace RCVCAT;
With RMAN connect on RCVCAT and create your catalog.

1.) For some reason I cannot get the mappings to work correctly, I have rebooted the server and tried a number of different changes in the rules script. But for the life of me I cannot get it work.
I noticed when I rebooted the server that it failed to execute the iscsidev. When I manually run the shell script with a parameter it produces output
Can anyone help me to get this up and running?
2.) My QNAP Nas doesnt seem to publish iSCSI targets to only one NIC. I think this is down to the firmware/feature not being available. When I discover targets I get the following

It shows the same targets on both NIC's, I only need them on the private ip 192.168.2.196

Hi,
I'm facing the same issue.. If your issue is fixed..could you please let me know?
I'm trying to configure 11g RAC with OPenfiler and got stuck here.

RAW disks for Oracle 10R2 RAC NO SUN CLUSTER

Yes you read it correctly....no Sun cluster. Then why am I on the Forum right? Well we have one Sun Cluster and another that is RAC only for testing. Between Oracle and Sun, neither accept any fault for problems with their perfectly honed products. Currently, I have multipathed fiber hba's to a Storedge 3510, and I've tried to get Oracle to use a raw lun for the ocr and voting disks. It doesn't see the disk. I've made sure they are stamped for oracle:dba, and tried oracle:oinstall. When presenting /dev/rdsk/C7t<long number>d0s6 for the ocr, I get a "can not find disk path." Does Oracle raw mean SVM raw? Should I create metadisks?

"Between Oracle and Sun, neither accept any fault for problems with their perfectly honed products"...more specific:
Not that the word "fault" is characterization of any liability, but a technical characterization of acting like a responsible stakeholder when you sell your product to a corporation. I've been working on the same project for a year, as an engineer. Not withstanding a huge expanse of management issues over the project, when technical gray areas have been reached, whereas our team has tried to get information to solve the issue. The area has become a big bouncing hot potato. Specifically, when Oracle has a problem reading a storage device, according to Oracle, that is a Sun issue. According to Sun, they didn't certify the software on that piece of equipment, so go talk to Oracle. In the sun cluster arena, if starting the database creates a node eviction from the cluster, good luck getting any specific team to say, that's our problem. Sun will say that Oracle writes crappy cluster verify scripts, and Oracle will say that Sun has not properly certified the device for use with their product. Man, I've seen it. The first time I said O.K. how do we avoid this in the future, the second time I said how did I let this happen again, and after more issues, money spent, hours lost, and customers, pissed --do the math. I've even went as far as say, find me a plug and play production model for this specific environment, but good luck getting two companies to sign the specs for it...neither wants to stamp their name on the product due to the liability. Yes your right, I should beat the account team, but as an engineer, man that's not my area, and I have other problems that I was hired to deal with. I could go on. What really is a slap in face is no one wants to work on these projects, if given the choice with doing a Windows deployment, because they can pop out mind bending amounts of builds why we plop along figuring out why clusterware doesn't like slice 6 of a /device/scsi_vhci/ . Try finding good documentation on that. ~You can deploy faster, but you can't pay more!

Oracle 12c - rman backup for all PDB

Do we have any ready commands that will take backup for all the attached PDB in oracle 12c (container managed db)?

To backup your entire container DB, connect to your CDB & issue a full backup:
rman> backup database;
Backing up your pdb, either connect to the target itself & issue a backup or
rman> backup pluggable database porcl1;
Backing up only the root, connect to the target &
rman> backup database root;
always condensed nicely here: ORACLE-BASE - Multitenant : Backup and Recovery of a Container Database (CDB) and a Pluggable Database (PDB) in Oracle D…
