Maintaining 200+ databases...

Hi All,
I just had a general question and that is that how does one maintain (install, patch,upgrade) 200+ Oracle databases? What is the trick? Would you install do it one by one? That would take forever. I never really thought to ask, but have always been curious.
Please pass on the knowledge.
Thanks in advance

Well,
think it of with the time frame. No company/organisation would have a need to create 200 databases at the same time. Of course, You would have to create databases(install, patch, upgrade) one by one as the need arises.
But maintaing is different. With Oracle Grid Control and all, you can do that. Even then, I strongly beleive that there should not be only one DBA, maintaining all those databases. There should a group of atleast 5 DBAs doing that, even though all are just monitoring the databases. (This is just my personal opinion)

Maintain standby database with DG

Good day,
I have primary and ph.standby databases.
I'd like to maintain standby database with DG(Data Guard), but DB_UNIQUE_NAME and SERVICE_NAME are the same for primary and ph.standby.
Is it possible to adjust DG broker?

To enable DGMGRL to restart instances during the course of broker operations, a service with a specific name must be statically registered with the local listener of each instance. The value for the GLOBAL_DBNAME attribute must be set to a concatenation of db_unique_name_DGMGRL.db_domain. For example, in the LISTENER.ORA file:
LISTENER = (DESCRIPTION =
(ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp)(HOST=host_name)
(PORT=port_num))))
SID_LIST_LISTENER=(SID_LIST=(SID_DESC=(SID_NAME=sid_name)
(GLOBAL_DBNAME=*db_unique_name*DGMGRL.dbdomain)
(ORACLE_HOME=oracle_home))

Logically, it should not work.

Maintaining LCES database

Hi,
In chapter 11 (maintaining the LCES database) of the "administering LCES" guide, I read the part "Oracle database: Modifying table indexes" on p. 112. The first thing is to modify the ix_45 index of the tb_assignment table, but in our database there is no such index for this table and the ix_45 index belongs to the tb_branch_instance table and has other columns.
The manual is from october 2008.
I have a new install of LCES 8.2.1 SP1 running on jboss 4.2.0.
Any explanation for this?
Kind regards,
Els

No one has tried this before? Or do you all have this index?
Please advice....
Thanks,
Els

Short dump while maintaining a database table

Hi SAP experts,
I have created a ZTABLE and a maintenance view for that.We have been maintaining the table since long.Today I opened the maintanence view( SM30) for that table.I clicked on the maintain button and went inside.I did slide the columns for the sake of my convineince .But when I clicked on the back button to come out,it suddenly gave me a dump.When I saw the dump analysis ,it has the following error analysis.
Error analysis:
Inconsistency with structure length of Dictionary structure "ZTABLE".
An inconsistency was discovered when the description of data type "ZTABLE" was accessed: According to the ABAP load, the structure should have been
279 bytes long, according to information from the ABAP Dictionary at runtime, the structure is actually 304 bytes long.
This situation may arise from changes being made to the structure at program runtime.
Please someone explain why the dump has come in detail.
Regards,
Rajesh.

Hello,
Seems that the table structure was changed and the maintenance view wasn't updated.
Try to generate the maintenance view again.
Regards.

How to maintain the data into database table

Hi,
experts,
how to maintain the data into database table

There are several ways to maintain data in the database
1. Use table maintanance generator . You can create this using SE11 and data can be edited through SM30.
2. Loginto SE11 with the specified table and check the ATTRIBUTES tab. There you can set some parameters for maintaining the database. When you set Maintain database, you edit the data thorugh SE11 it self
3. Through Se16 as well.
4. A small abap program can do the above task as well.
Thanks,
Raj

Managing&Auditing Database Physical files.

Hi all,
Sorry if I posted this issue in this forum.
I have just this problem in monitoring and auditing oracle files and disk spaces in our Windows server.
We have a server farm of around 20 Windows server, for global centralized test servers.
Each server has different versions of Oracle DB, and maybe contain more than 10 database/intance (small test DBs).
So we monitor around 200+ Databases.
We run backup daily for each db using cold backup and maintain at least 1week retention files.
We we have around 5x10x200 backup zip files.
We also monitor all the Physical list of DB_home folders and it corresponding .dbf files and timestamp.
What I did is map all the hardrive from each servers on my laptop to I can read all and audit all the physical files.
I want to have a centralized list of the files associated with the database in spreadsheets and update it periodically.
My question is how can I run a list cascade command that will list all the files and sub-directories and saved in in .csv or excel file?
Is it like "ls -lt">list.log in linux.
Thanks

How to use another database schema in Dictionary project

Problem description:
1)     I want to use Developer Studio to create my own J2EE project. Then I have to use Dictionary Project to maintain my database. My database is Oracle.
2)     I created tables in Dictionary project and deployed to database
3)     After that I found my tables were deployed into SAPSR3DB schema.
Question:
      What can I do if I want to deploy my tables into another schema other than SAPSR3DB? In real cases I want to separate my tables from the WAS system tables.

Hi Chaoran,
If you want to use external database with Java dictionary tables..
Right click on the Java Dictionary Table, from the menu select <b>Create DDL script</b>, then select to which data base you want to generate scripts. It will generate .sql scripts, use this scripts in your database to create tables. But the same time you need to create Data sources in Visual Administrator for your oracle system.

Aperture Library/Database hacks

After one week playing around with aperture, i want to share my current insights with 'customizing' (my) aperture's way of dealing with my picture files.
Warning:
The following thoughts and arrangements are working for me, they're
undoubtly NOT supported by apple and the programmers of the aperture
application!
Reading a lot of articles in the forum when aperture hit the masses, i've been disappointed about how aperture will fit with me.
Over the years my growing picture collection moved over from one computer to the other, deploying more storage, and will continue to do so in the future. So the technical equipment has to be independent from the treasure's of my data, to follow state of the art hard- and software development.
For me, aperture approved to be of such a kind.
Despite aperture stores away all my digital masters into it's own Library, thus duplicating data during imports, it just brings in some kind of more detailed
directory hierarchies to my way of organizing my picture library. How does it do?
How do i store my Library?
Sorry to be that longish, but to explain my concepts i have to.
Modern operating systems distinguish private/personal and public/common data for their file storage locations. Hopefully they follow the 'FHS' (Filesystem-Hierarchical-Standard) brought up by linux, to name the diverse locations for classified data.
I do run mixed os'es within my networks, as no computer should be isolated from a networked environment anymore. But to be honest it's more a single-user situation in reality, then the multi-user aspects i always keep in mind when designing my infrastructure environment for a network.
My picture library/online-archive is classified 'common' data, so it stores outside my home-directory, and every user allowed to, has access to it. I do not support locales within my filenaming-conventions, users and me are german-spoken, so the 'common' data for my systems is always called
'/Bibliothek'.
Furthermore we're dealing with pictures (Bild), movies (Film), music (Musik) and documents (Dokumente) in all common used operting systems (os x, windows), storing private data to the home-directory within appropiate directories and public/common data to the equivalent directories at a common storage.
/Bibliothek
/Bibliothek/Bildarchiv
/Bibliothek/Filmarchiv
/Bibliothek/Musikarchiv
BTW, i customized windows to reflect this filetree within explorer windows, so users click to 'Eigene Bilder' (my pictures) and 'Bildarchiv' (common pictures) there, to change between directories, making it very convenient to work with.
Especially the 'common' picture files are strongly organized by date, which is reflected at the directory-structure, for example:
'/Bibliothek/Bildarchiv/2004/2004-04-17, make a good description/'
'/Bibliothek/Bildarchiv/2005/2005-12-00, a bunch for the whole period/'
A descriptive directory name is highly portable between operating systems, applications and last but not least, users!
For now, aperture seems to be pretty much a single-user solution.
But it's library can be 'distributed' to accomodate my needs.
I started to import my data by drag'n'drop, which works best for me. I didn't like the import assistent, which seemed to result in a different structure of my data in aperture's 'all projects' list. By creating a folder in aperture for the year, then drag'n'drop the multi-selected directories from the finder, i got within aperture:
All Projects + * (<-Aperture)
<div class="jive-quote">Library (smart-albums, collapsed)
2005 (folder)
2005-11-00 (folder, nested)
2005-11-17, sample bla (project, from directory)
Images from 2005-11-17, sample bla (album, inherited)
2005-12-08, take a better name (project)
Images from 2005-12-08, take a better name
Using aperture's preferences to switch between libraries i did import to different aperture libraries for the years, resulting in a bunch of directories, each holding an 'Aperture Library.aplibrary' paket there.
/Bibliothek/Bildarchiv/2004/2004.aplibrary
/Bibliothek/Bildarchiv/2005/2005.aplibrary
Yes, the pakets can be renamed, to better reflect whats in there. Aperture has to be restarted to change from one library to another!
The total amount of imported data, yet: 130 GB, ~33164 pics.
I am working with a 15" powerbook, 1,5gb ram, 80 gb hdd on the road and a 200gb external drive at home/office.
to make me feel comfortable with aperture, i switched to (terminal hacking!):
~me/Pictures/Aperture Library.aplibrary/
~me/Pictures/Aperture Library.aplibrary/2004/ ->
/Bibliothek/Bildarchiv/2004/2004.aplibrary
~me/Pictures/Aperture Library.aplibrary/2005/ ->
/Bibliothek/Bildarchiv/2005/2005.aplibrary
~me/Pictures/Aperture Library.aplibrary/Texturen/ ->
/Bibliothek/Bildarchiv/Texturen/Texturen.aplibrary
~me/Pictures/Aperture Library.aplibrary/...
/Bibliothek/Bildarchiv/2004/2004.aplibrary
/Bibliothek/Bildarchiv/2005/2005.aplibrary
/Bibliothek/Bildarchiv/Texturen/Texturen.aplibrary ->
/Volumes/HD39.1/Bibliothek/Bildarchiv/Texturen/Texturen Library.aplibrary
Linking folders to where i believe they are right placed in my systems.
Now aperture's settings don't have to be changed each time to switch between libraries. Not connecting the external hdd gives me grayedout
folders within aperture, for data stored on the external drive. Having a folder located on my inetrnal hdd and 'linked' to aperture:
~me/Pictures/Aperture Library.aplibrary/local ->
/Bibliothek/Bildarchiv/working.local.aplibrary
i can work with aperture normally, even if the external drive is not available.
the grayedout folders/subfolders/projects are browsable, but all thumbnails are just gray rectangles with its 'version name' underneath. same with smart-albums. available pics have colored thumbnails, unavailable pics are gray, naturally.
And aperture's database? well, i am very happy with it, really. Compared to my pre-aperture structure all the above mentioned tweaking gave me:
~me/Pictures/Aperture Library.aplibrary/Aperture.aplib/Library.apdb
This file is actually the sqlite3 database file. it's size is 111 MB now.
~me/Pictures/Aperture Library.aplibrary/Local ->
/Bibliothek/Bildarchiv/Working.local.aplibrary
I can store pictures there into folders and projects when i am on the road, filling up my local harddisk. Inspecting the paket shows up how aperture differenciated my pre-aperture filestructure:
/Bibliothek/Bildarchiv/Working.local.aplibrary/2005-12-08, take a better name.approject/2005-12-08 @ 01/49/06 PM - 1.apimportgroup/DSC0168/dsc0168.nef
All nicely packed into a single unit from the finder, easily browsable from aperture, and searchable by sql queries. Every Master enclosed in its own folder box, hm. Every import of files seperated to one folder, which makes clearly apparent that we will import redundant(duplicate) files for ever.
Adding two/three levels to my previous filestructure, strange namings all inclusive. As i sort my files with aperture into projects, the files accordingly move around at the filesystem-level. I'll let them go. They are there if i need access to them in case of failure.
T H E G L I T C H E S
within my setup the most current sql database is stored at:
~me/Pictures/Aperture Library.aplibrary/Aperture.aplib/Library.apdb
importing the way i did results in a sqlite3-database file for each library i switched to before linking them together. Right after linking one of those aplibrary pakets as a new folder, aperture will rebuild the current database at startup, which can indepently be invoked with 'option command aperture' anytime the program is started.
Changes to the metadata of a picture are written to the current database aperture is running on, but can be transfered to any other database file
when rebuilding the library at startup (which can be a time-consuming thing!)
Even if the external hd is reconnected before startup, some thumbnails are not properly generated all the time. At the current state i don't have any glue what's the cause for this. All Versions are properly accessable anyway.
Once again,
DO THIS AT YOUR OWN RISK,
if you try some of the suggestions i've made. Better you know how to handle a terminal before you even think about what i told here. Don't bother me, if something does not work for you - it works for me.
I can do this because it's my data, i am the only one affected by failure and i still do have my data on my windows system as a backup, for now.
Do the same before you trash your treasures.
Why i did made this post? Aperture really lacks support for team-working now. I cannot see how aperture can be really employed to its potential for an environment with more than a single user?. The sqlite3 database is said to handle concurrent users, i read on its homepage. So i still hope, there will be a group-worked aperture someday.

my reports, just for the logs.
drwxr-xr-x 2 fo03c fo03c 68 Dec 19 20:15 ArchiveInfo
-rw-r--r-- 1 fo03c fo03c 362 Dec 19 20:17 DataModelVersion.plist
-rw-r--r-- 1 fo03c fo03c 173107200 Dec 20 00:26 Library.apdb
comparing the timestamps, the time needed to recreate 'my' library, is:
4h 11 min.
The sql database contains 972 projects with 57952 picture items, as the startup overlay tells me. not that bad, i think. depends on the situation, and how much zen you learned, if you can wait for the 'recreate'.
but i didn't stop to mature aperture!
i switched to one of my 'old' libraries (choosing from preferences panel) and set some new
a) ratings
b) keywords
c) deleted a master from that 'old' library.
after changing back to the 'linked' aperture database file (within my home-directory, as described previously), and restart aperture -
yes, it crashed! oops.
yet another try - crash. i realized, i deleted the first pic from the 'current view' aperture tries to load after relaunch. ?! =:-(
if the database is corrupted again, i would have to reinvest ~4 hours to recreate the database? but how about the preferences?
apple this is a bug! when i made the preferences file
~me/Library/Preferences/com.apple.Aperture.plist
UNAVAILABLE (delete or rename as you like), aperture starts with the import assistent, as at its first time.
Since then i can start aperture and navigate to the project i deleted the file from (very unpolitly). The corresponding thumbnail shows up with a new 'icon' to lower right corner of the thumbnail. It clearly means: this file is UNAVAILABLE.
YES =:-) i deleted it!
the rating and keywording on the 'old' database is gone -
thus making the precedence of the database against the sidecars obvious, doensn't it?
selecting the 'orphaned' thumbnail, now leaves aperture with the message 'loading', but it does not crash. Changes in ratings or keywording to the current library (the 'recreated' new one) on different files are persitent across restarts of aperture. btw, aperture restarts with the focus on the orphaned first thumbnail, now marked with the icon 'i am NOT available', but it does not crash anymore, when starting.
my conclusion:
someone in the forums pointed towards the difficulties maintaining a database of pictures and the separation of their storage, as users will delete or move files seperated from that database, breaking everything.
NO, aperture does widely tolerate such doing.
But why should we do so? =:-)f
For me: its fun, i will not complain about failure, when i do mature an application like this.

Jsp database connectivity

To maintain the database connectivity, we are trying to keep the database 'Connection' in the session object (putValue, getValue). Do anybody see any problem with there? Any comment appreciated.
Thanks.

Your suggestion is a simple way to avoid reopening the db connection for the same user. It will work, if the number of concurrent users is not that big. If the number of concurrent users is very big, connection pool would be needed.
You may want to take a look into HttpSessionEventListener. If your db connection is "unbound" from the session, you may want to close the connection. Otherwise, you will reach the max number of connection very soon.

Java feat database(MySql)

I am trying to write a single-client/server application which maintains a database. The client app sends request to server which executes the request and returns the result to the client. The GUI on the client side must be able manipulate the database by: creating tables, load tables with the serialized files, insert data, delete data, manipulate Booleans and do calculations.
Question 1: In my class how do I initialize the Boolean? Referring to the text book (JAVA Sixth Edition) Chapter 14, I created the class and a different class with the same info except for the import of the Serializable class/(function) in a package that I created. Both classes are in there.
Problem 1: How do I declare the default constructor of a Boolean? For numeric and string value it seems easy e.g.:
public class Serializable()
this(0," "," ",0.0);
But for a Boolean?
public class Serializable()
this(" "," ", ?); - >string, string, Boolean
I have made compensation for handling a ClassNotFoundException, but that error message is about all it gives me. Where did I go wrong????
Problem 2:How do I code the other functionalities? The book only talks about viewing information from the database, nothing about creating and loading tables
let alone insert and delete.
It does talk about a script that is on the CD to create the tables in MySql, but I don't have the CD. Can I use such a script in my client app?
Are there some examples of such applications on the net or are there scripts I can refer to, that might help me?
Please help :-{
Thanx

This is what my record is suppose to look like:
package DvdPackage;
import java.io.Serializable;
public class Movies implements Serializable
private String title;
private String category;
private boolean newRelease;
private boolean availableForRent;
public Movies()
this("","",true,true);
public Movies(String Title, String Cat, boolean New, boolean Avail)
setTitle(Title);
setCategory(Cat);
setRelease(New);
setAvailable(Avail);
// set methods
public void setTitle(String Title)
title = Title;
public void setCategory(String Cat)
category = Cat;
public void setRelease(boolean New)
newRelease = New;
public void setAvailable(boolean Avail)
availableForRent = Avail;
//get methods
public String getTitle()
return title;
public String getCat()
return category;
//checks if the movie is a new release
public boolean getNew()
return newRelease;
//checks if the movie is available
public boolean getAvail()
return availableForRent;
The reading a serialized class looks like this:
import java.io.*;
import DvdPackage.Movies;
public class ReadingFiles
private ObjectInputStream input;
public void openFile()
try
input = new ObjectInputStream(new FileInputStream("Movies.ser"));
catch(IOException ioException)
System.err.println("Error opening the files.");
public void readRecords()
Movies record;
//System.out.printf("%-40%-40%-10s%10\n", "Title", "Category","New Release","Available");
try
while(true)
record = (Movies) input.readObject();
System.out.printf("%-20%-20%-1s%1\n",
record.getTitle(),
record.getCat(),
record.getNew(),
record.getAvail());
catch(EOFException eofException)
return;
catch(ClassNotFoundException classNotFound)
System.out.println("Unable to create object.");
catch(IOException ioException)
System.out.println("Error during the read of the Movies file!!!!");
public void closeFile()
try
if(input != null)
input.close();
catch(IOException ioException)
System.err.println("Error closing movie File!!!!");
System.exit(1);
The code runs with no errors, but it stops at the "ClassNotFound" handler.
What is wrong with my code?

Oracle RMAN recovery catalog database in a Primary and Standby mode

Hello All,
The customer wants the RMAN recovery catalog database to be highly available so that none of the RMAN database backup jobs are impacted at the time of taking the database backups. There are are 200+ databases running on OEL, RHEL and Windows. So we planned to host the recovery catalog database on Oracle Active DataGuard 11.2.0.1 Enterprise Edition on RedHat EL 5.8 version on two physical servers. The Primary Instance will be in one server in the Primary DC and the Standby Instance will be on another server in another DC. Also all the database datafiles are hosted in ASM Diskgroups on SAN (DATA, FRA, REDO, ARCH diskgroups).
Are there any specific RPM/patch/OS user custom/specific settings or configurations needed..?
Thanks in advance..
Regards,
Abhijit

"The customer wants the RMAN recovery catalog database to be highly available so that none of the RMAN database backup jobs are impacted at the time of taking the database backups"
Hi,
i think you can achieve HA for the catalog DB. (Rac and Asm should work fine)
There's no way (afaik) to use TAF with the rman backup. If you have a failure during a backup it simply fails.
There is no TAF in this situation.
Hope this helps.

How to secure database

hi,
i newly joined a company, where i need to maintain oracle database running on linux system.

2. except application database user (like scott) developer doesn't have any other user password but except this is there any way developer or any other third person can access oracle database?
3. any recommendation from expert to secure database from unauthorized access?

What is the best way to copy database from overseas?

Hello All,
As customer need to migrate their databases(200 databases) to our data center, at this moment, we usually ask customer to send full backup by HDD and then send trn files via FTP, then we restore full backup and apply latest trn files until cutover. However
FTP is not stable, trn files are always broken.
The databases size are 3GB~150GB, trn file size are 1MB to 5GB, especially the big trn files are failed every time, we have set transfer mode to Binary in FTP client, but it still fails.
I have VPN access to their database server, so in this case is there a better way to copy/migrate their databases to our server?
Customer using Windows 2003 + SqlServer 2008
We using Windows 2012 R2 + SqlServer 2014
Appreciate your suggestions/advises.
Thanks,
Albert

You are doing it the best way. I would also ship the tlogs via courier if time permits. Note that the tlogs get very large during maintenance operations. You may find that if you continually ship the tlogs via log shipping and stagger the cutover you may
be able to do this in waves.
With this many databases this sort of migration is difficult without downtime.

Path to database - SQL Toolkit

Hi !
I succesfully use SQL to maintain a database. Now I'd like to get the directory
name where that database is located as a character string. Again: opening
the database there's no problem after DBConnect( "DSN=SOFTPROD" ) but now
I'd like to get the directory where DBConnect found the database (it uses
the ODBC settings I suppose). Does anybody know ?

I think you have to search in the MSDN to use directly the ODBC functions.
The SQLtoolkits functions such DBTables(), DBDatabase() can't do such a thing.
The ODBC functions allows you to create a DSN, and ....
