Server Administration :: Copy Many Files From ASM To FileSystem

May 1, 2013

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.

RAC/ASM Clusterware Installation :: How To Copy ASM Files On Host Filesystem

Oct 15, 2013

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.

ASMCMD> cp spfilenode.ora /u01copying +DATA/NODE/spfilenode.ora -> /u01/spfilenode.ora 

Now my question is, Can I copy/delete/move that file on OS filesystems when the ASM instance is down.

SQL & PL/SQL :: Copy Some Archivelog Files Between 2 Database Server

Sep 27, 2011

I wanted to copy some archive log files between 2 DB Server.Steps:

1) Edited the Local and Remote DB's TNSNAMES file and modifyied like below.

bookstore =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.80.100.28)(PORT = 1521))
)
(CONNECT_DATA =
(SID = BOOKSTORE)
)
)

2) Created a Source Directory --> DR1
3) Created a Target Directory --> DR2
4) Created a DB Link
CREATE DATABASE LINK LINK1 CONNECT TO <username of the Remote DB> IDENTIFIED BY <Password> USING '<Remote DB Name taken in the TNSFILE>.
5) In the Local Server I had written the below command.

create or replace procedure proc1 is
cursor c1 is select recid,substr(name,37) "ARCH_FILE" from v$archived_log;
var1 c1%rowtype;
begin
open c1;
fetch c1 into var1;
[code]...

It is working, but not coping the Files from Local To the Remote.

JDeveloper, Java & XML :: Copy Files Into System Directory?

Mar 15, 2011

I am on a font manager project. One of the features is to install the new font file. My understanding by "install" is to copy the file to the system directory Windows/fonts (correct me if I am wrong in this part). When I tried to use the java copy file api to do so, not surprisingly I got the access denied exception.

1. How can I do a "force-copy" of file into the system directory?

2. If that's not proper way, how can I create a "shortcut" like a softlink of the file into the system directory?

Server Administration :: Contents Of Redo Log Files

Feb 1, 2011

I have some doubts about redo log files,

1) Can we fetch 'select statements' from redo log files through the use of log miner utility or any other?
(I think redo log file contains only insert,update,delete and DDL/DCL commands only)

2) If "No" to the above answer then how can i fetch all select statements fired on the system for a day or particular time.
(setting of sql_trace may be the one of them, but can it be possible for system level)

SQL & PL/SQL :: Impact Of Create Directory Statement On Filesystem

Mar 3, 2011

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.

Recovery Manager (RMAN) :: Backup To Filesystem And Not ASM In RAC

Aug 27, 2012

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.

Performance Tuning :: Oracle Buffer Versus AIX Filesystem Cache

May 7, 2011

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.
