Oracle database down need help

My company is using a program called Digital Collections (DC4) from GMTI. We have an oracle database on the backend. Recently the server's raid array fan went out and we lost all 5 drives. We were able to recover some of the lost data from backup tapes but we can't seem to locate the oracle 8.0.5 install CD's. Now, I can only download 9i which as I understand will not access oracle 8 files. All the migration howto's start by dumping the data from oracle 8 and then importing to 9i. But if I don't have 8 running how can I dump the data? Does anyone know of a solution. Either a method or utility to dump the data from the raw files or a link to download 8.0.5 Any help will be greatly appreciated.

You can't attach oracle 8 version datafiles to 9i database or vice-versa. It was DBA's responsibility to keep the backups in case of disaster occurs at any time.
Check with your friends about the availability of oracle 8, you will get it, if you are lucky enough.

How to configure Oracle database in a failover zone cluster

Setup: Oracle database and zone configured on highly available local filesystems.
Two node cluster.
Oracle database running inside the zone.
Note: I dont have a zone cluster.
1. I need to make the zone and the oracle database highly available.
2. Can I configure the Oracle Data service directly to run in the zone or will it involve creating sczsh_config script to do the same.
I have been going through the guides and searching over the net, but haven't found any help so far. Its so much simpler to configure this environment in Veritas cluster. Hope I find some help here.
TIA,
Sudhir

The Oracle Solaris Cluster concepts guide has some information on which zone model to choose:
http://docs.oracle.com/cd/E18728_01/html/821-2682/gcbkf.html#scrolltoc
When managing a Solaris zone with the HA Zones agent, the cluster basically regards the non-global zone as a blackbox.
As such you can either start the Oracle database as part of the runlevel/SMF startup of the non-global zone, or you can use the sczsh or sczsmf component and use your own scripts to start, probe and stop the Oracle database.
Usage of the standard HA Oracle data service is not supported in combination with the HA Zones agent.
If you require a more fine grained control of services running in non-global zones, why not setup a zone cluster and then having HA Oracle failover the Oracle database between non-global zones?

EM12c Oracle Database Plug-In 12.1.0.7 update now shows 10g listener as down when it's not

EM 12.1.0.4 with Oracle Database Plug-in 12.1.0.7
Monitored database and listener: 10.2.0.4
Our EM12c monitors 12.1,11.2 and 10.2 databases and listeners. All monitored targets are up and running.
I updated Oracle Database Plug-in from 12.1.0.6 to 12.1.0.7 and now the only 10g listener that I have shows as down.
The listener on the server is up and running.
The monitoring configuration is right.
I removed this target and re-added it, but it came back as down.
It's a little disconcerting to have a listener show as down since it's a production box, but nothing I do corrects the problem.
Any insights or suggestions are appreciated.

Hi Sherrie,
In most cases we have this issue due to monitoring configuration , I know you mentioned that you have checked on it but still I would recommend to just re-confirm on below steps
1. Go to
    EM Console -> Targets -> Listener -> Listener Home page -> Target Setup -> Monitoring Configuration
2. Get the details
      Listener Name
      Listener.ora Directory
      Machine Name
      Oracle Home
      TCP Port Numbe
3. Go to the server where this listener is running
   Check to see if the listener is up
       ps -ef | grep tns
4. Next run
       $ORACLE_HOME/bin/lsnrctl status
   From this outpuy verify details in (1)
      Listener Name   <======= Alias
      Listener.ora Directory <=== Listener Parameter File ie the directory
      Machine Name <======= HOST=
      Oracle Home<========== This is where tnslsnr is started from
      TCP Port Number <====== PORT=
5. Makes sure that all the details matches in (4) and (2)
If above is fine then I would recommend to go through the troubleshooting steps as per below doc , they are valid for listener status down too and should give a further insight on the root cause of the issue
Troubleshooting the 'Pending' status for a Listener Target in Enterprise Manager 12c Cloud Control (Doc ID 1546576.1)

What steps to follow to make RAC Database down.

hi all,
I need to know the order which we have to follow in making RAC database Down Completely,
Information reg database:
OS::IBM AIX,
ASM Storage,
2 node RAC,
2 databases.
order in the sence to shutdown the RAC database first what we have to shutdown like ,
database,asm,cluster, etc.and also give respective commands for reference.

The first step is to stop the Oracle instance. When the instance (and related services) is down, then bring down the ASM instance. Finally, shut down the node applications (Virtual IP, GSD, TNS Listener, and ONS).
$ export ORACLE_SID=orcl1
$ emctl stop dbconsole
$ srvctl stop instance -d orcl -i orcl1
$ srvctl stop asm -n linux1
$ srvctl stop nodeapps -n linux1
Starting the Oracle RAC 10g Environment
The first step is to start the node applications (Virtual IP, GSD, TNS Listener, and ONS). When the node applications are successfully started, then bring up the ASM instance. Finally, bring up the Oracle instance (and related services) and the Enterprise Manager Database console.
$ export ORACLE_SID=orcl1
$ srvctl start nodeapps -n linux1
$ srvctl start asm -n linux1
$ srvctl start instance -d orcl -i orcl1
$ emctl start dbconsole
Start/Stop All Instances with SRVCTL
Start/stop all the instances and their enabled services. I have included this step just for fun as a way to bring down all instances!
$ srvctl start database -d orcl
$ srvctl stop database -d orcl

answered by ssolbach
Just a minor comment on the stop nodeapps.
While it is fine to stop the nodeapps on the server, the drawback to this is, that the VIP will not failover if you stop the nodeapps, but will be stopped.
Hence if you only shutdown one server, then you are causing clients to fail to connect to the VIP and having to wait for the TCP/Timeout.
So if you are not going to shut down all the server, but just want to shutdown one node, you should failover the VIP the the other node.
See: Note 749160.1 Vip Does Not Failover When Nodeapps Stopped
So it is sometimes better instead of stopping the nodeapps, to simply shutdown the cluster with crsctl stop crs (which will failover the VIP).

Re: RAC Questions

Database link failover on RAC

Dear Friends.
Could you please provide me the information about implementation of Database links failover in RAC. (Oracle 10g RAC on linux)
I have created db links across the two RAC environments. Each RAC setup contains 2 nodes.
I have created DB link across the two RAC environemtns.
i.e I have created DB link between 1st node of Source RAC system to 1st node of Target RAC system.
If 1st node of Target RAC system is down, I need to setup in such way that the link should failover to node 2 of Target system.
I have tried all possible options of TAF. But I did not succeed. Is there anybody is implemented this type setup...?
How to setup tnsnames.ora on source DB to get this type of failover.
Thanks in Advance.
Best Regards
Kanumuri Raju

Oracle was kind enough to provide some configuration details in their docco. You may want to review this link:
http://download-east.oracle.com/docs/cd/B19306_01/network.102/b14212/advcfg.htm#sthref1275
The configuration needs to be performed in the TNSNAMES.ORA associated with the database initiating the link. If you want bi-directional TAF, you would need to update the TNSNAMES.ORA for 'both' databases.
I suggest you don't get your hopes up too high about the capability of TAF across DBLinks. I'm pretty sure you will not be able to get SELECT-based TAF. And I'm not absolutely sure which session rules will be used to determine the failover time.

OS level Cluster and Oracle Database...

Is there a way to install one oracle database, on two servers that are set up in a Cluster on Operating System level so it can see it as one machine, that is: I want to use the capabilities of two servers, but to have Oracle Database see it as one server with two processors, drives etc.? Thanks,

A pure OS cluster can only act as a failover cluster, but it cannot emulate RAC functionality.
The database (single instance) runs on one node, in case of node down, it can be switched to the other node.

Not able to connect remote oracle database over VPN

I can not connect remote oracle database over VPN. tnsping is ok and it shows the server information of remote database. i can also telnet the 1521 port of remote database server. I can connect the same server when it is located in the same LAN. Please help me out this is very urgent.

First, this is a forum of volunteers. There is no "urgent" here.
"Urgent" means one of two things -
1) people are dying, or
2) you have a customer-facing, revenue-producing production system that is down.
(And to get some perspective on the second case, keep the first in mind.)
For the first, you call whatever civil emergency service seems appropriate.
For the second, you open an SR with Oracle - which requires a paid-up support contract. For *them* to consider your problem "urgent", you will need to demonstrate that your problem falls under item #2. I seriously doubt your problem fits that criteria.
You don't have a support contract? Now you know the exact dollar figure that your company places on the data.
That said, you need to understand a few things about your specific problem,
First, port 1521 is only used by the listener to accept a connection request. Once it gets that request (and finds that it is for a service (sid) that it knows about, it will fork a server process and tell the requesting client that it can communicate with that server process over some other port .. a randomly chosen port number in the "high" range. It could be your vpn is blocking that other port, whereas your internal firewall is not.
But this is just an educated guess since I cannot find "can not connect remote oracle database over VPN" in any error message manual. If you had mentioned the VPN along with an actual oracle error message we could be much more precise in our diagnoses and recommendations.
---- edit 22 Sep
It occurred to me that I just assumed you were using the same client machine in both cases ... a laptop that you use both at work (local network) and home (vpn). If that assumption is false, there are probably problems with your tns setup on the home (vpn) machine.
But again, it would be much easier to help if you gave us an actual error message.

Can't mount oracle database on linux system

This is same as previous posting just added
e-mail and username info fo forum posting.
I am not able to mount an Oracle database.
I am new to Oracle and am working on an Oracle8i installation on an
Intel Linux Suse 6.3 platform. I am using only one harddrive and am
not using the 4 mount points as mentioned for efficiecy purposes in
the Oracle documentation..I am using the installation cd from Oracle8i
for Linux Starter Kit by Oracle Press. If anyone has this book they
can refer to pages 41-44 for the examples I followed.
As sysdba in sqplplus using the STARTUP command I can not Mount the
database -step 2 of the 3 stage process (Start, Mount and Open the

I show the errors I encountered when I did the first 2 of the 3 steps
in the step-by-step mode (STARTUP NOMOUNT pfile=, ALTER DATABASE
MOUNT) in the sqlplus session and alert log respectively with startup
nomount and alter database mount for this sqlplus session.
Additionally I show the init.ora file lines referring to control file
which seem to be referred to by the sqlplus error messages and the
alert.log file. Perhaps some can give me some advice as what I can try
to fix this problem.
At the end of this e-mail I added several questions I had in regard to the control

init.ora control files
# define two control files by default

Here are my control file questions:
I need to know several points:
1) What are control files susposed to
contain and how would I recognize them?
I used the
unix find /usr/oracle \*ctl* -print
command to locate files with a ctl extension.
This resulted in about a dozen such files in
different directories as shown below:

2) On page 100 in the book Oracle 8i A Beginners's
by Oracle Press mention is made of a
CREATE CONTROLFILE command that can under
circumstances be used to re-create a control-file.
but that is all that is said about it. Perhaps
you might know something more about it.
3) Would you recommend any good text for
Oracle DBA's, especially for the problem of the sort
that I am encountering?

It's probably not supported on RHEL5/Centos5/etc., but...
You can get the installer to function using the following steps:
- extract the cal_linux_*.tar.gz, and cd into the OracleCalendar_inst directory
In there is the actual installer, cal_linux.
- the cal_linux is shell script wrapped around some binary blobs. The installer's
problem is that Oracle is setting the LD_ASSUME_KERNEL=2.2.5 environment
variable, which is a mistake on RHEL5. You need to make it not set that variable,
but you need to do so in a way that the size of the shell script does not change at all,
and none of the binary blobs are impacted.
- the approach I took was
mv cal_linux cal_linux.BAK
sed -e 's/LD_ASSUME_KERNEL=2.2.5/LD_ASSUME_KERNEL= /g' < cal_linux.BAK > cal_linux
chmod a+rx cal_linux
cal_linux -i gui
Note: you must have exactly 5 spaces in the substitution part of the sed command, because you're replacing 5 characters (2.2.5), and the size of the shell script must not change.
If you do that, the installer should run (one warning from awk still) and you should be able to install the product.

Hi everyone!
The following are the steps to load a excell sheet to oracle table.i tried to be as simple as possible.
thanks
Step # 1
Prapare a data file (excel sheet) that would be uploaded to oracle table.
"Save As" a excel sheet to ".csv" (comma seperated values) format.
Then save as to " .dat " file.
e.g datafile.bat
1,Category Wise Consumption Summary,Expected Receipts Report
2,Category Wise Receipts Summary,Forecast Detail Report
3,Current Stock List Category Wise,Forecast rule listing
4,Daily Production Report,Freight carrier listing
5,Daily Transactions Report,Inventory Value Report
Step # 2
Prapare a control file that define the data file to be loaded ,columns seperation value,name and type of the table columns to which data is to be loaded.The control file extension should be " .ctl " !
e.g i want to load the data into tasks table ,from the datafile.dat file and having controlfile.ctl control file.
SQL> desc tasks;
Name Null? Type
TASK_ID NOT NULL NUMBER(14)
TASK_NAME VARCHAR2(120)
TASK_CODE VARCHAR2(120)
: controlfile.ctl
LOAD DATA
INFILE 'e:\datafile.dat'
INTO TABLE tasks
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
(TASK_ID INTEGER EXTERNAL,
TASK_NAME CHAR,
TASK_CODE CHAR)
The above is the structure for a control file.
Step # 3
the final step is to give the sqlldr command to execute the process.
sqlldr userid=scott/tiger@abc control=e:\controlfile.ctl log=e:\logfile.log

How to import a table from another oracle database ?

Hi all ,
i could like to use pl/sql to import one table from another oracle database server ?
is it possible to do this ?
A server B server
table: test <------------------------> table : newtest
the tns profile already configurated . the connection is ready .
thanks a lot !
Best Regards,
Carlos

if i don't have TEST table on server B whether COPY command will create this table on server B with the same structure ? If you specify CREATE as a clause the table will be created:
SQL> help copy
COPY
COPY copies data from a query to a table in a local or remote
database. COPY supports CHAR, DATE, LONG, NUMBER and VARCHAR2.
COPY {FROM database | TO database | FROM database TO database}
            APPENDCREATE|INSERT|REPLACE} destination_table
            [(column, column, column, ...)] USING query
where database has the following syntax:
     username[password]@connect_identifier

Using AE(htmldb 2.0) as for reporting tool for other oracle databases.

Maybe I was mistaken, but when I first saw the HTMLDB demo's I saw this as a slick way to build a browser based reporting tool for the masses for quasi-ad-hoc reporting on some of our larger databases that currently have limited reporting capability, and also as a possible replacement for the many MSAccess applets we have.
I just got 2.0 installed and working on a 9i database and went through the basic tutorials, but I can't find much info on how to connect to other oracle databases.
Are my options as follows?:
create dblinks from the local database that houses htmldb to all the other databases?
or
install htmldb schemas on each database I want to access from htmldb?
or
I'll keep looking, but if any of you have any pointers or know of a tutorial that explains the best way to do this it would be greatly appreciated!

As for question 1, yep, that's what I mean. Example:
In a schema in the App Express instance, create a user called "APP1_USER", and then
create view app1_user.people as select * from people@link_user@remotedb
As for the next question, using the built-in insert/update/delete processes will give you
ORA-01461: can bind a LONG value only for insert into a LONG column
among other errors. Apparently version 2.1 will fix this. See Cannot Update VARCHAR column in Remote DB
We address this problem by creating pl/sql APIs for DML, and then writing our own insert/update processes. Slows us down a little, but even with that, App Express remains a productive choice for us.
Another weird problem: auto-row fetch (built-in to HTML DB) doesn't work over db links when you have two columns for a primary key. Many ways around this, e.g. create sequence-populated primary key, create a view with single column that concatenates primary key column values (key1|key2)
Hope this helps!

Error when installing 9.0.1.4.0 patch set for the Oracle Database Server.

Hi to all.
Currently, i am trying to install patches for portal server.
The server OS is Sun Solaris 8.
We are using Oracle9iAS.
Now, we are installing 9.0.1.4.0 patch set for the Oracle Database Server.
We managed to install the patch, but have problem with the Post Install Action.
We managed to run
-ALTER SYSTEM ENABLE RESTRICTED SESSION;
-@rdbms/admin/catpatch.sql
-ALTER SYSTEM DISABLE RESTRICTED SESSION;
-CONNECT / AS SYSDBA
-update obj$ set status=5 where type#=29 and owner#!=0;
-commit;
But, when we come to the next command, which is to shutdown, it gives us like
this..
SQL> update obj$ set status=5 where type#=29 and owner#!=0;
1402 rows updated.
SQL> commit;
Commit complete.
SQL> shutdown immediate
Database closed.
Database dismounted.
ORA-00604: error occurred at recursive SQL level 1
ORA-01219: database not open: queries allowed on fixed tables/views only
We tried to startup the database..it gives us this error..
SQL> startup
ORA-01081: cannot start already-running ORACLE - shut it down first
So, we tried to shutdown again..
SQL> shutdown immediate
ORA-01089: immediate shutdown in progress - no operations are permitted
I been informed that this is maybe a Database problem related. Any ideas?
Best Wishes,
Rushdan Md Saad.

Patchsets could be obtained (only) from http://metalink.oracle.com
You need to have valid CSI for access.
P.S: Sorry Werner, I didn't see you post.

Oracle Database 10.2.0.3 on Windows 2003 x64

We are looking to migrate our 2 Oracle database servers from old Windows Server 2003 machine to our new HP-G5 Windows Server 2003 64-bits. We're using ESX Server with Windows Server 2003 Virtual Machine and our 10.2.0.2 are running fine. Some months ago a consultant warned us from installing the 10.2.0.3 upgrade for some stability bugs on Windows Servers were to be found.
As the new CPU (Jan 2008) is not available for Windows Server 2003 64-bits for Oracle 10.2.0.2, I would like to upgrade from 10.2.0.2 to 10.2.0.3. I would like to apply these patches to our OAS too. Is anyone had exprience any issue with this kind of configuration ?
Configuration :
Database is on a Virtual Machine which we allow 4Gb RAM and a Quad Core.
Windows Server 2003 Enterprise 64-bits.
Our Application Servers 10.2.0.2 run on Windows 2003 32-bits.
We're still using Oracle Forms & Reports 10.1.2.0.2.
We also use Oracle Discoverer 10g.
We also use a failover system with EMC Legato.

Before proceeding with the Virtual Machine, I suggest you to refer to this Metalink Note> Certified Software on Oracle VM
Doc ID: Note:464754.1
This doesn't seem to be a supported platform, so if you ever find an issue after upgrade you may find your production system unsupported by Oracle.
