Configuring rman channel

hi,
while taking backup we are configuring channels based on cpu's right?
so, how i can fine no. of cpu's on my machine and how many channels can allocate per cpu.

If you don't know how to retrieve the number of CPUs on your server, you are probably not the right person to configure RMAN backups :-)
Jokes aside: Number of CPUs is not the only factor to estimate the number of channels. Isn't one channel fast enough for your backup? Do you backup to tape or disk? Do you backup during end user activity? What kind of storage (RAID, ASM, Number of Drives) are you using? How big is your database? What is your time window for the backup?
That is a list of factors to take into account that I think of first.
Kind regards

Configuring RMAN for dataguard.

Hi all,
Here we have a dataguard environment with db1(db_unique_name) as primary and db2(db_unique_name) as physical standby database. For both primary and secondary the ORACLE_SID is 'oracledb'.We configured dataguard in 10g environments and we are not using grid control. And now we want to configure rman for incremental backups. We are using a third catalog database to which we registered from primary db successfully. During primary rman configuration it is showing conflicts. Even the changes made in primary RMAN configuration are applied on to the standby too which i think shouldn't happen in this scenario. How to resolve this issue? Is this happening because of the same ORACLE_SID for both primary and secondary? I'm attaching the link of the doc that we followed also the errors and configuration in rman. Can anyone help?

hi
what is SBT here?
CONFIGURE DEVICE TYPE sbt PARALLELISM 3;
Channel Connections to Cluster Instances with RMAN
Channel connections to the instances are determined
using the connect string defined by channel configurations.
For example, in the following configuration, three channels are allocated using dbauser/pwd@service_name. If you configure the SQL Net service name with load balancing turned on, then the channels are allocated at a node as decided by the load balancing algorithm.
CONFIGURE DEVICE TYPE sbt PARALLELISM 3;
CONFIGURE DEFAULT DEVICE TYPE TO sbt;

Very first step in configuring RMAN for a Backup

DB version:10gR2
I am a DBA supporting applications development and i am not familiar with RMAN. This weekend we are going to Patch 10.2.0.1.0 to 10.2.0.3.0. Before that i am going to take a backup of the entire Database containing around 57 schemas(total of around 600gb).
We don't have Tape drives. I am going to backup this up on three filesystems in the same machine. This instance is not running on ASM. What is the first step i should be doing in configuring RMAN for a backup?
Edited by: user10583227 on Jan 27, 2009 4:50 AM

Be careful, three filesystems doesn't necessarily mean the use of three channels. Could be more...could be less.
Are you in a position to shutdown the database? If not, you'll also want to backup the archivelogs with BACKUP DATABASE PLUS ARCHIVELOG. You may also consider creating a Guaranteed Restore Point which would allow you to rollback your database in minutes if the upgrade fails.

Rman Channel 2 to network drive

I have configure the channel 2 to mapped network drive. Both are on Windows 2003 platform.
CONFIGURE DEVICE TYPE DISK PARALLELISM 2;
CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT 'D:\Rman\backup_db_%d_S_%s_P_%p_T_%t'MAXPIECESIZE 1024m;
CONFIGURE CHANNEL 2 DEVICE TYPE DISK FORMAT 'Z:\backup_db_%d_S_%s_P_%p_T_%t'MAXPIECESIZE 2048m;
Channel 1 backup is ok, but there is a error given for channel 2
channel ORA_DISK_2: starting piece 1 at 09-JUL-08
RMAN-03009: failure of backup command on ORA_DISK_2 channel at 07/09/2008 09:46:40

O/S-Error: (OS 3) The system cannot find the path specified.

Oracle doesn't support network drives.
You would need to run Oracle as domain administrator. This poses security risks.
This is why Oracle doesn't support this.

RMAN / channels and device types

Hello,
I have a question.
In the RMAN documentation (for instance in "Oracle Database Backup and Recovery Advanced User's Guide 10g Release 2") one can find the description / instructions how
to allocate RMAN channels and define the device types.
There are 2x described device types - DISK and SBT (Tape).
My question is:
IS IT POSSIBLE TO USE A PIPE AS A RMAN DEVICE TYPE ?
If it is not possible to define direct, perhaps there is a possibility to define it
indirect and to use a pipe to write data.
Regards.
Neitour

Thank you for the link. Is it this RMAN 'duplicate database' option, what you
would like to recommend me to use?
I think, it is not exactly what I really need. For 'duplicate database' I will need
to have as a source a backup of the database and not a running productive
database.
Is it correct?
If it is, it is not what I'd like to do.
I'd like to make a copy of a productive running database, which is placed on ASM
storage, to another server creating such a way a database also placed on ASM
storage. I'd like to do it directly. I think the best possible way can be
RMAN / BACKUP --> PIPE --> RMAN / RESTORE.
The issue is - how can I configure RMAN to write BACKUP into a PIPE and
to read data for RESTORE from a PIPE.
Any ideas?

Hi ,
I think its better idea to give you some more links in addition to above post and let youtry to achieve it instead of giving the direct solution.

Configure Interface channel monitoring for PI in SOLMAN 7.1

Hi Experts,
I am configuring interface channel monitoring for PI in SOLMAN 7.1.In step 5 (Define scope) it is asking to select scenario.I can see all PI systems (Dev,QA and PRD) is listed in the table with "monitoring and alerting setup status" as yellow.when I select PI (prod) and proceed , in step 6.3 (Interface channel Monitoring config) I don't find any channel name in table.I need your support to clear my understanding on this.
1)My objective is to monitor all the interfaces that are existing between PI system and other SAP as well as non SAP systems (that include JDBC connections also).How can find all these interfaces in solman while doing Interface channel monitoring config?
2)I am not sure if I have understood correctly that I need to create scenario that includes technical systems between which Interface channel are to be monitored. If I am correct then how can I bring the technical system to SOLMAN SLD from Local SLD of PI(prod).Here I am not getting option to synchronize SOLMAN SLD from PI Local SLD. Even Import option is also not there. Do I need to create all the Technical systems (present in PI) to SOLMAN SLD manually?
If my understanding is not correct then please guide me through steps to do the configuration to achieve my objective.
Thanks
Aditya Roushan.

yes, the problem solved. thanks for your replies all.
the users SLDDSUSER and SLDAPIUSER got locked, I changed it in su01.
and I created rfc in SM59 for SAPSLDAPI and LCRSAPRFC and create the same in JCo RFC provider.
both are working.
but iam facing new problem.
I have solution manager 7.1 system and I configured local SLD. I did not connect any managed system as of now.
after all the trouble shooting, SLDAPICUST and SLDCHECK is fine but
the error is
"Functional call returned exception code 3"
"Access to XI Profile currently disrupted.
I have solution manager 7.1, I did not configure managed systems as of now. is this error belongs to solution manager 7.1 or for PI system.
can u please guide me how to trouble shoot this error. check the following screen shot for reference.
thanks in advance.

What should be configured as channel in Oracle CEP HTTP adapter for remote publishing?

Hi,
Below is the adapter configuration that I have for Oracle CEP HTTP adapter for remote publishing. What exactly should be configured in <channel> here? In the oracle documentation example, it only says /channel2 as an example.
Below is the HTTP adapter configuration file that I have created.
<?xml version="1.0" encoding="UTF-8"?>
<wlevs:config xmlns:wlevs="http://www.bea.com/ns/wlevs/config/application">
    <http-pub-sub-adapter>
        <name>HttpPostAdapter</name>
        <server-url>http://localhost:8080/RESTfulWS/rest/UserInfoService/post/jsonstream</server-url>
        <channel>/RESTfulWS</channel>
        <event-type>com.wipro.event.ResultEvent1</event-type>
    </http-pub-sub-adapter>
</wlevs:config>
'/RESTfulWS' in my above configuration is the context-root of my rest service.But this is not working so I would like someone to help me understand this configuration.
Many thanks.
Regards
Sowmya

Hi, Sowmya,
From your configuration
Is the http://localhost:8080/RESTfulWS/rest/UserInfoService/post/jsonstream httppubsub server? I don't think the oep http pub adapter can publish event to rest service.
For http pub adapter, you can take a look at fx sample, it publishes events to a embedded http pub/sub server of oep.
Thanks,
Gala

Configuring rman for dataguard environment.

Hi all,
Here we have a dataguard environment with db1 as primary and db2 as physical standby database. We configured dataguard in 10g environments and we are not using grid control. Can anyone provide the steps for configuring rman for incremental backups in this environment? We want to schedule the backups to be taken in standby db, (that is applicable in case of swithover too). In the case of swithover to db2 what all do we need to do in rman manually to resume backups in db1?
Thanks

Hello;
A Standby database is a copy of the Primary so if you try to register it RMAN will probably tell you its already registered. I would start with this :
Standby based backup
1. Enable auto backup of the control file and server parameter file. CONFIGURE CONTROLFILE AUTOBACKUP ON.
2. Skip backups on datafiles already backup. CONFIGURE BACKUP OPTIMIZATION.
3. Set the archive deletion policy. CONFIGURE DELETION POLICY TO NONE.
You have to decide on the exact RMAN script you want to use, but since the database is registered you can perform backup on either the Primary or the Standby as the need arises.
See "Using RMAN to Back Up and Restore Files" in "Data Guard Concepts and Administration 10g Release 2 (10.2) B14239-05"

Prerequisites for configuring RMAN

Hi All,
My database is in AIX Box..
I have to configure Rman backup in Windows system..
What are all the prerequisites for configuring the Rman?

Hi!
OK. I'll post the content of this website:
A database cloning procedure is especially useful for the DBA who wants to give his developers a full-sized TEST and DEV instance by cloning the PROD instance into the development server areas.
This Oracle clone procedure can be use to quickly migrate a system from one UNIX server to another. It clones the Oracle database and this Oracle cloning procedures is often the fastest way to copy a Oracle database.
STEP 1: On the old system, go into SQL*Plus, sign on as SYSDBA and issue: “alter database backup controlfile to trace”. This will put the create database syntax in the trace file directory. The trace keyword tells oracle to generate a script containing a create controlfile command and store it in the trace directory identified in the user_dump_dest parameter of the init.ora file. It will look something like this:
    STARTUP NOMOUNT
    CREATE CONTROLFILE REUSE DATABASE "OLDLSQ" NORESETLOGS
    NOARCHIVELOG
    MAXLOGFILES 16
    MAXLOGMEMBERS 2
    MAXDATAFILES 240
    MAXINSTANCES 1
    MAXLOGHISTORY 113
    LOGFILE
    GROUP 1 ('/u03/oradata/oldlsq/log1a.dbf',
    '/u03/oradata/olslsq/log1b.dbf') SIZE 30M,
    GROUP 2 ('/u04/oradata/oldlsq/log2a.dbf',
    '/u04/oradata/oldlsq/log2b.dbf') SIZE 30M
    DATAFILE
    '/u01/oradata/oldlsq/system01.dbf',
    '/u01/oradata/oldlsq/mydatabase.dbf'
    # Recovery is required if any of the datafiles are restored
    # backups, or if the last shutdown was not normal or immediate.
    RECOVER DATABASE
    # Database can now be opened normally.
    ALTER DATABASE OPEN;STEP 2: Shutdown the old database
STEP 3: Copy all data files into the new directories on the new server. You may change the file names if you want, but you must edit the controlfile to reflect the new data files names on the new server.
    rcp /u01/oradata/oldlsq/* newhost:/u01/oradata/newlsq
    rcp /u01/oradata/oldlsq/* newhost:/u01/oradata/newlsq
    rcp /u03/oradata/oldlsq/* newhost:/u03/oradata/newlsq
    rcp /u04/oradata/oldlsq/* newhost:/u04/oradata/newlsqSTEP 4: Copy and Edit the Control file – Using the output syntax from STEP 1, modify the controlfile creation script by changing the following:
Old:
    CREATE CONTROLFILE REUSE DATABASE "OLDLSQ" NORESETLOGSNew:
    CREATE CONTROLFILE SET DATABASE "NEWLSQ" RESETLOGSSTEP 5: Remove the “recover database” and “alter database open” syntax
    # Recovery is required if any of the datafiles are restored
    # backups, or if the last shutdown was not normal or immediate.
    RECOVER DATABASE
    # Database can now be opened normally.
    ALTER DATABASE OPEN;STEP 6: Re-names of the data files names that have changed.
Save as db_create_controlfile.sql.
Old:
    DATAFILE
    '/u01/oradata/oldlsq/system01.dbf',
    '/u01/oradata/oldlsq/mydatabase.dbf'New:
    DATAFILE
    '/u01/oradata/newlsq/system01.dbf',
    '/u01/oradata/newlsq/mydatabase.dbf'STEP 7: Create the bdump, udump and cdump directories
    cd $DBA/admin
    mkdir newlsq
    cd newlsq
    mkdir bdump
    mkdir udump
    mkdir cdump
    mkdir pfileSTEP 8: Copy-over the old init.ora file
    rcp $DBA/admin/olslsq/pfile/*.ora newhost:/u01/oracle/admin/newlsq/pfileSTEP 9: Start the new database
    @db_create_controlfile.sqlSTEP 10: Place the new database in archivelog mode
I hope that this could be of any help to you.

How to configure ether channel

Hi mates,
As far as I know, when you configure ether channel (PAGP/LACP) on two ports, they act like one port. but in reality packets are not sent through both ports. Only one of the ports is used until the actual link fails.
Question is:
I have two switches, each has two SFP ports, I want to connect two switches each other.
how can I make ether channel always use both ports when sending/transmitting packets? I remember it is possible.
thanks for helping :)

HI
i hope this link will help u .

when u create ether-channel it will automatically load balance based on source/destiantion mac address or source/destiantion ip address.
Thanks

What am I doing wrong, did I miss something?
NLS_LANG can only be set at OS level: as env. var. in UNIX/Windows and as registry setting in Windows.
See OTN NLS_LANG FAQ http://www.oracle.com/technetwork/database/globalization/nls-lang-099431.html.
For example in Windows 7 if I want French settings and keep same character set:
set NLS_LANG=FRENCH_FRANCE.Edited by: P. Forstmann on 2 févr. 2013 20:42

Configuring DAQ channels through LabView program

Hi,
I want to scan one analog input of PCI 6025E every 250 msec and I scan 8 such channels. I am using AI Sample Channel VI to do this and for its channel input I am feeding a string (with channel name) that is typecasted using a Traditional DAQ channel constant. All the required channels are configured using this constant. However this VI doesn't seem to be portable. When I use it on a different machine, the constant shows no channels defined.
Is there a way to configure DAQ channels through my program such as to make the program portable? I came across notes that mentioned DAQ global channel but I don't know how to use it.
Thank you in advance,
Sharmila

One of the great things about DAQmx is that there are only 4 basic VI's to learn to use. The Configure, Read, Write and Stop. The same Configure VI that was used to setup the analog input channels can be used to setup analog output, digital in/out and counter in/out.
The small menu on the bottom of the VI is actually a listing of all the different operations that this single polymorphic VI can do. Click on the down arrow and you'll see what I mean.
I've modified the example to read DIO lines 0-3 and write to lines 4-7 on Port 0. Again it programatically builds the channel list so it will always refer to the correct device. To create individual channels for a digital line, you first specify the device, then the port, then the line or lines. Example, to create a task for lines 4-7 on port 0, you would use "Dev1/port0/line4:7".
Notice that the "DAQmx Create Channel.vi" is the same one used in the analog input configuration, but with different polymorphic selections. Also note the "DAQmx Read.vi" is the same except for the selector.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.
