RAC & Failsafe :: Unable To Mount Ocfs2 Filesystem
Feb 7, 2011
I am configuring RAC with two nodes. I have mapped iscsi targets successfully. I am unable to mount the ocfs2 filesystem.
mount -t ocfs2 -o datavolume,nointr -L "oracrsfiles" /u02
When execute the above command, it displays the follwing error:
ocfs2_hb_ctl: Device name specified was not found while reading uuid
mount.ocfs2: Error when attempting to run /sbin/ocfs2_hb_ctl: "Operation not permitted"
For RAC with ASM, user can not browse the ASM files. From within NTFS or ext2( for linux) they are not seen. Similarly, for OCFS2 , are these oracle files not seen through ext2 , linux file system? Also, for RAC with ASM if I query v$datafile, it returns +diskgroup/dbname/datafile.dbf. What will be the file name returned for datafiles in OCFS2 by this view?
I am attempting to install Oracle 10g R2 on Oracle Enterprise Linux 5 update 5 but facing some errors. Can't believe i have done everything right as far as oracle docs n my understanding concern. when i try to invoke runInstaller for CRS it fails with following error: ------------------------------ [oracle@server01 clusterware]$ ./runInstaller Starting Oracle Universal Installer...

We are configuring NAS device on linux for RAC installation.
ISSUE: I had mounted NAS device to Linux server.As root user I can create directory but cannot change owner of cifs mount.It say permission denied.When I try to change permission it doesn't work.The mount point show the uid and gid as 33 and permissions drwxr-xr-x

when i'm creating ASM instance, i'm getting an error

for this there were some workaround given to start css.
i tried everything from /etc/init.d/init.cssd start/enable but nothing worked, then i tried with executing
localconfig delete localconfig add====>it failed and recommended to go for reset option
when i executed localconfig reset i get this following error:
Quote: [root@rac2 bin]# sh localconfig add Successfully accumulated necessary OCR keys. Creating OCR keys for user 'root', privgrp 'root'.. Operation successful. Configuration for local CSS has been initialized
I tried to run the duplicate script after transferring new rman backup to standby. Even after transferring the backup, duplicate command and was unable to open the database.
I have a RAC working with SAN raw devices presented to ASM and working fine. My situation has changed since the installation of the RAC. Now I need a shared storage (with a filesystem) to upload some files (so DB can read these as external tables) for this I have used OCFS2.
As you can see I have Oracle RAC on raw ASM + shared storage on OCFS2 and for the time been all seems to be well and working perfectly. Can these coexist with out effecting the other?
how can I connect via ftp to the xmldb-filesystem ?
I tried the instructions from this website [URL] ..... Now I can connect to the filesystem via "win7 shell ftp", but i cannot connect via "win7 explorer" using "ftp://host:port/foo/bar" or filezilla. Everytime i try i got an errormsg like:
filezilla: cannot read filesystem and win7 an error appears : detail: 200 Type set to A. 277 Entering Passive Mode.... see sreenshot -> [URL]
I am attempting to read from the maillog of our server, but I wish to make as few changes as possible for fear of blocking other systems access to the file.
I was initially going to call create directory maillogs as '/var/log/maillog' and then drop directory maillogs; when I was done but I found my user does not have "create any directory" permissions.
Rather than compromise security of the existing database configuration, I thought I would permanently add the maillogs to the list of available data directories. Are there any implications to the filesystem if I do this, or should I be able to add this without consideration of affects.
Understand that I will only be opening the file for (R) READ TEXT access only.
Primarily I am concerned that Oracle (in the background) will keep a file pointer open or something of that nature that would block other programs from writing to the file even after I close the file pointer. I want to make as little impact as possible to the file system.
I have got backup pieces in ASM, I guess about more than 100 files. Now, I need to copy all of them from ASM to FileSystem, there are 2 methods still now:
1- Copy from ASM to FileSystem using cp command. 2- Copy from ASM to FileSystem using DBMS_FILE_TRANSFER.
But:
In the first method, when I copy one file, I took more than 1 minute, so the following script would take me more than 1 days (I guess so).
#!/bin/ksh # # This script copies files from FRA on ASM to local disk # ORACLE_SID=+ASM2 ASMLS=/vasgatedb/app/vsgbkp/asm_ls.txt ##{ASM files list}
[Code]...
The second method, DBMS_FILE_TRANSFER took me less than 1 second to copy one file completely.
sys@VSGDB> set timing on sys@VSGDB> exec dbms_file_transfer.COPY_FILE('asm_dir','level_0_vsgdb_9998_813844797.bkp','fs_dir','level_0_vsgdb_9998_813844797.bkp');
PL/SQL procedure successfully completed.
Elapsed: 00:00:00.38
Of course, I wish I used the second method as soon as possible, however, said I below, I've got about ~200 files, and I could not copy one by one file.
I am using Oracle 11.2.0.3 RAC (2 nodes) + ASM on AIX 7.1
I am backing up my Oracle database through RMAN to ASM disk groups..I have a requirement to backup also to an OS file systems. So what I did that I mounted an NFS across the 2 nodes of my RAC database.I am running backup from node 2 only.My issue now is that I am facing a real performance issue when backing up to NFS.My question is there any way to take an RMAN backup to local file system on node 2? or in other way what are the options to take RMAN backups to an OS file system?
I tried to copy from ASM to OS file system but i was advised to backup to file system using the format command.what should i do in such case? since I am facing performance issue to backup to NFS.
I have a requirement where I have to generate monthly filesystem usage report(graphical) in an automated fashion,I checked the built in reports from the grid control 10g but not able to find any thing....
What is correct way to move the default oracle spfile to ASM diskgroup so i can successfully bring up the instance . After bring up the instance , it should point to ASM diskgroup. My oracle database 11.2.0.3 is siting on sun solaris 64 Bit.
There is a question come up in my mind that can we perform the copy/delete/move of ASM files to the host filesystem while the ASM instance is down. For instance... To copy the file ASM file through AMCMD utility when the ASM instance is running.
I am currently in the favorable situation in which I have excess amounts of memory available on the database server - a single node setup. The server only serves the single instance and no other processing. Database size is around 2.3tb and memory is 50gb. For the majority of processing, AIX is allocating a significant amount (anywhere from 30-40%) of the memory to the AIX file system cache (persistent pages).
I've been trying to find documentation about this, but have not had any luck yet. My guess is that it would be better to allow Oracle to cache this data - meaning increase the SGA target and max size to allow for a larger buffer cache. However, the nice thing about the AIX cache is if process memory is needed, the file system cache gives up pages. If the memory was allocated to the SGA, its pretty much locked in.
I have read several articles stating that a larger buffer cache is not always better, as a larger cache takes more management. But having both of the caches active seem to be a waste of memory, effectively storing the data twice - once in AIX persistent pages and a second time in Oracle database buffer cache.
While I was trying to configure an Oracle DB called "NW6" using the Database Configuration Assistant, I have Oracle 11.2 database installed on a Windows 2008 Server, the configuration wizard thrown an error : ORA-01507:database not mounted
So I am not able to successfully complete the DB configuration. Also I tried to test the service using the net configuration assistant, it throws an error: ORA-27101 shared memory realm does not exist.
I started database in mount state;startup mount; alter tablespace users offline;
I tried to make tablespace offline In another case online but showing error database not open same for command alter tablespace begin backup; do think we can make tablespace offline in mount...
Table D-7 shows a hierarchical file mapping of a sample OFA-compliant installation with two Oracle home directories and two databases. The database files are distributed across three mount points, /u02, /u03, and /u04. URL....
why three mount points (/u02, /u03, and /u04) for datafiles? don' understant this. isn't it better to store all datafiles in one mountpoint?
I want to shutdown the database using shutdown immediate and startup the database using startup mount.
1.)My system is client system if I connect start--> program -->Accessories --> communication --> Remote Desktop connection (connect server system) , open Run type cmd after
Shutdown immediate (database is shutdown)
Startup mount (database is mounted no problem it's working fine)
2.) But if I, open Run type cmd in client system If I run same command, I'm getting below error (ORA-12560: TNS:protocol adapter error).

How i create Standby Database in Same HOST, we using SUN OS 5.8.
I read form Oracle DOC that i can create Standby Database in Same HOST and follow the tutorial , but when i try to mount standby database using ALTER DATABASE MOUNT STANDBY DATABASE EXCLUSIVE; i got a error message ORA-01102: cannot mount database in EXCLUSIVE mode
I performed Shutdown Immediate in Oracle 8I and now I am unable to mount the database.I'm getting the following message: ORA-01102 Cannot mount database in Exclusive mode/I only have one database running on this machine. It was automatically created by Oracle installer upon installation of Oracle software. I can no longer connect via SQL * Plus,Only through Server Manager (connect internal)
I'm trying to create a physical standby database on my Oracle9i DB runing on WinXP.
Note: I have both Primary and Standby on the same system.
Actually everything went well .... I did created the standby DB but the problem is I can not start my primary DB if my standby DB is mounted. I get this error:
ORA-01102: cannot mount database in EXCLUSIVE mode
And when I read about the error message I learnt that I should start my DB in compatible mode ...
We have one primary oracle database 10.2 and standby by database with no data guard. Initially we have 2 redo log group in primary and standby database.
We have recently add 2 more redo log and increase the size of log member from 50m to 200m in primary database. We don't have any problem in primary database.but in standby database we face a problem because we cannot open it. It always in mount stage in which . How we change the size of current redo log because we can't run. Alter system switch logfile command in mount stage.
