Oracle 10g Corruption

High level issue - Oracle 10g with patch p4756409_10201. What seems to be happening is Oracle
gets into this weird state that even a stop and start of oracle or even a reboot of the system doesn't allow even the sysdba to connect to the db even
through sqlplus. Doesn't matter which node we try it on. Additionally, we will notice that as we are in this state before the reboot
even with our software shutdown we still have a few Oracle process (LOCAL=NO) still listed. I believe that means Oracle is hanging onto a connection for some reason which
could explain the memory corruption. I wouldn't think that anything we could do would cause Oracle to crash but I guess I'm naive in this area.
The trace files don't tell you much except for those great ORA errors that state "yes, oracle error go figure it out".
The ORA error that is seen in the trace files is
ORA-07445 exception encountered cor dump [kponprp()+59][SIGSEGV] [address not mapped to object][0x0][][]
According to what I've read this issue is suppose to be fixed in 10g.
Any help or guideance would greatly be appreciated.

That function call is not yet listed as known issue with Metalink ORA-07445 look up tool.
I guess its time to contact Oracle support.

Oracle 10g corruption type 'unknown'

I don't see unknown listed in the oracle docs as a corruption type.
10.2.0.3
DB in archivelog mode with weekly full backups
We only keep 1 backup. No tape backups (no space. no budget for tape. Its a development environment. )
All DBs are run from vmware. Not sure that matters
OS: Solaris.
checked both: v$database_block_corruption and v$backup_corruption
What is corruption_type = 'UNKNOWN' its not in the docs? All of my corrupt blocks in both views say 'unknown'
This is not production. Its development. So loss of data is not a big issue. Just trying to understand the situation.
It has been a number of years since I have had to repair block corruption. Please let me know if I am interpreting my findings correctly.
v$backup_corruption: I have corruption in my backups
v$database_block_corruption: corruption in my current DB
I only have 1 backup. (no space. No budget for tape backups... this is not production. working off of VMs. not exactly high end hardware).
Here are some additional questions:
1. Tried running a blockrecover. Did not expect it to work since the backups appear to be corrupted too. However, I did expect RMAN to tell me that I can't fix the blocks. dd thing is I didnt get any errors. I didn't expect the blocks to be repaired since the backups are corrupted. However, I did expect some kind of message or exception. How come oracle didn't say 'hey we can't repair this'
surprised that oracle is not telling me, I can't repair these? They dont get repaired almost certainly because the backup has corruption. Did I do something wrong or is this expected? After running this I checked v$database_block_corruption and nothing changed.
[code]
RMAN> blockrecover datafile 15 block 19621,19624,19608,19611,19617,19613;
Starting blockrecover at 07-AUG-13
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=288 devtype=DISK
starting media recovery
media recovery complete, elapsed time: 00:00:00
Finished blockrecover at 07-AUG-13
[/code]
2. I think my only other option is to use dbms_repair to flag these blocks as ignore. I know the segments involved and I can afford to ignore blocks in them. Its not the data dictionary. Is there something else I should look at?
3. If we change the rman backup command to backup validate, will this prevent the backups from running if there is corruption and generate an error? I can write a job that can look for it and send me an email.
4. would dbverify provide me with different data than what I got from rman?
Anything I am missing from my approach?

How did you determine that you've corruption in your database and in your database backups ? Any ORA- errors or messages?
What is the output of the views ?
2. I think my only other option is to use dbms_repair to flag these blocks as ignore. I know the segments involved and I can afford to ignore blocks in them. Its not the data dictionary. Is there something else I should look at?
did you try to create the corrupted segments using CTAS ?
Backup validate will only validate, by default RMAN should fail if it encounters corruption (unless specified otherwise). And I think, RMAN/dbv will provide the same output.

Oracle 10g DB download for Windows is corrupt

The link for Oracle 10g For Windows (10g_win32_db.zip, 604,263,765 bytes) is working, however the zip file is corrupt and won't extract fully.
Is another download available?

We suggest the use of a download manager such as getright (getright.com; free) to ensure download stability...

Oracle 10g + VMware Workstation 6.5 = data block corruption?

I'm trying to run Oracle 10g on VMWare Workstation 6.5 (host and guest are windows 2003)
I've noticed a couple times that I easily get block corruptions and wonder if there are some settings to lower the risk.
Note this is a DEV machine, not a production machine.
I don't know if Oracle supports the set up but I'm sure many people are running Oracle in Vmware so I'm looking to those who have done so successfully.
Anyone know of special precautions in either Vmware or Oracle config to limit the risk on block corruption?
According to VMWare, ESX is a perfect platorm so maybe I should move from Workstation to ESX, maybe it has to do with Windows in VM and Linux would work better.
Anyone has some info on why Oracle has block corruption on VMware Workstation (windows/windows)?
Other people with positive/negative experience on VMWare Workstation (mention OS's and Oracle version please)
(before someone tells me it's not supported, also see these pages on vmware.com:
http://blogs.vmware.com/performance/2007/11/ten-reasons-why.html

Well, it's indeed not for production, I use it for product demos and small development tasks, there is no critical data in my database but I wished I could run Oracle inside a VM on my laptop...
It works reasonably well (I even have run multiple VM's (Workstation) with Oracle insde on 1 laptop (4 GB Ram, Core Duo), but sooner or later it gives some problems. If there is any setting that can lower the risk would be great.
I was thinking of installing ORacle VM but apparently my laptop is not compatible with that (nor with ESX for that matter).
Anyone use plain Xen (which seems to support any processor) + Oracle on Linux ??
I can't install Oracle natively on the machine directly since I need the capabilities of a VM in respect of easy backup + I have many different applications and databases so depending on what I need to show, I just start a different VM
The VM provides the capabilities to move back to previous situation, exchaning demos with collegues, have multiple parallel copies with different configurations (depending on customer), etc...
... installing natively is too much of hassle, we used to swap hard disks but that's a pain when the hardware changes, at least with VMWare WS you can run it on pretty much any computer.
How do other people deal with this type of situation?? We have ESX on a hosted environment but internet access is not always available...
It seems stable enough to run my demos (I'm doing this for quite a while but the block corruption seems to happen sooner or later)
The problem is that I first need to get the demo installed without corruptions. Once it's installed I can just restart from that situation over and over again, but obviously I don't want to run the risk of having a disk corruption in the middle of a demo.

Oracle 10g RAC on 2 VMware Windows 2003 images corrupts image

It happened twice on each of the 2 VMware workstation 5 on which I am trying to set up an Oracle 10g R2 RAC. After installing CRS and rebooting machine I lost access to the Network Connections and the Disk Management. Basically I have to create a new image. Before I start a third time I would appreciate advice or feedback from other users.
Also Configuration Assistants failed to install.
Thanks

Check out my articles at http://dbasupport.com on 10g R2 RAC Clusterware setup. I was able to do that on my vmware BUT I hope to have the very irritating ASM scenario done before my 4th Article.
Check it out.

Apex 3.1.2 installation on Oracle 10g Standard Edition (10gSE)

Hi..We're trying to install apex 3.1.2 on 10gSE (No application server 10gAS is available but just the database).
Can it be installed with the embedded plsql gateway (EPG) option?
or
Oracle HTTP Server mod_plsql option?
Currently there's Apache webserver already running on the box with PHP applications running. Want to make sure that apex/http-server install will not corrupt the existing environment.
Please provide any pointers/references. IF YOU CAN OFFER PHONE SUPPORT FOR 1-2 HOURS, YOUR TIME IS Sincerely APPRECIATED. PLEASE EMAIL: [email protected] For Direct contact. Also, I may need help to solve some apex screen issues.
* Removing the tagging with $ compensation on the post..Apex Community as in the past has been extremely helpful in solving many great apex challenges. Thanks for the continued support. *

1- Here is what I mean, the oracle website is showing Web Logic in the download page of oracle application server:
http://www.oracle.com/technology/software/products/ias/index.html
Is there a separate download link for Oracle Application Server, if it's different from the web logic server?
2- I Installed HTML_DB which is found in the Oracle 10g companion CD, I think I installed the HTTP Server with it, but now I want to install APEX 3.1.2 which I downloaded separately, if I uninstalled the HTML_DB using Oracle Universal Installer, will it remove the HTTP Server as well? since it lists the HTML_DB only as being installed without listing the HTTP Server separetly.
Thanks.

1. Is this a Driver related issue? Because when we were using Merant ODBC driver, everything seems to be working fine!
2. Is there some patch that is out there which might resolve this issue?
If you all folks could help or provide some kind of advice , i would really appreciate that.
regards,
GG

Well, do you have a code example that causes it? Don't take this the wrong way, but I've seen more than a few badly written multi-threaded applications which do nothing but corrupt memory and use handles in non-threadsafe ways; all of which cause issues which rear their ugly heads in various odd ways. It may also be an Oracle bug, but comparing two different drivers does not mean it's not your application causing the crash as well.
If you could provide a quick little code sample which causes the issue, I'll take a look at it for you.

Oracle 10g EE Export Results in ORA-01001: invalid cursor Error

Hi,
I'm quite new to Oracle 10g and OCS10g. We have a crippled/corrupt SYSAUX tablespace (data file 3) which cannot be recovered using recover
command anymore. So metalink support instructed us to do a export of the metadata of the working tablespace which contains our system data (we are in configuration stage for OCS 10g 10.1.2) via transportable tablespaces so that I can just recreate the database in DBCA and import the metadata. So after I made a cold backup, set the "transportable" tablespaces to "READ ONLY" mode, I proceeded w/ the export command which resulted in an error, please see below:
$exp \'sys/********@ocs10gSID as sysdba\' parfile=transport.par
Connected to: Oracle Database 10g Enterprise Edition Release 10.1.0.4.2 -
Production
With the Partitioning, Real Application Clusters, OLAP and Data Mining options
Export done in US7ASCII character set and AL16UTF16 NCHAR character set
server uses AL32UTF8 character set (possible charset conversion)
Note: table data (rows) will not be exported
About to export transportable tablespace metadata...

ORA-06512: at "SYS.DBMS_PLUGTS", line 1444
ORA-06512: at line 1
Anyone encountered this problem before? Any recommendations or tips to get this working?
I checked this url:"http://luhartma.blogspot.com/2006/05/how-to-check-if-tablespace-is.html"
And when I try to follow the instructions and check on of the tablespace I set to and verified to be in "READ ONLY" mode, I get the same error.
SQL> connect / as sysdba
Connected.

Hope someone can help on this or at least provide a suggestion. Data file 3 above is the reason we are doing a transportable tablespace export & db recreation.
BTW what we have is:
OCS 10g 10.1.2 w/ Oracle RDBMS 10g Enterprise Edition 10.1.0.4.2
RHEL4 Update2
Thanks in advance.

Hi,
The status is "RECOVER" we have actually tried to recover but unfortunately the archive logs that were needed were on disks and were lost during one of the server hardware failures. Actually that is the reason why metalink support recommended this route for getting everything in order since we don't have any application data in SYSAUX yet.
Thanks.

Oracle 10g R2 - Unicode is converted to unknown ?��

Ok, I've read a thousand posts. Tried everything still stuck.
I am using Oracle 10g : 10.2.0.5.0
I'm on a Mac, using SQL Developer 3.1.07
When I enter "ė€£¥©", the insertion into the database converts it to: ?��
This is straight from a SQL INSERT command, in SQLDeveloper, no java code or anything.
I tried adding a file called SQLDeveloper.app/Resources/sqldeveloper/sqldeveloper/sqldeveloper.conf and added these lines:
-Doracle.jdbc.defaultNChar=true
-Doracle.jdbc.convertNcharLiterals=true
Didn't help.
I tried created a test column and made the datatype NVARCHAR2. same results. VARCHAR column does the same corruption but that's expected.
I tried N'©' - doesn't work
I tried INSERT INTO testchar (column1) VALUES ( unistr('©') );
results is still : �
I check NSL_NVAR_CHARACTERSET and it's UTF8

I have read that the insertion into the database does its own conversion but I don't know if that applies to me since I'm in 10g R2

NLS_NCHAR_CHARACTERSET specifies the encoding of the NVARCHAR2 variables but not the SQL statements. SQL statements, when they arrive to the database server, are always encoded in the database character set (NLS_CHARACTERSET). This is true for the whole statement, including any character literals. Therefore, even if a literal is valid in SQL Developer (which works in Unicode), when the literal arrives to the database, it is already stripped of all characters that the database character set does not support. The characters are not actually removed but they are converted to a replacement character. In case of the US7ASCII database character set, anything non-ASCII is lost.
The trick to avoid this problem is to:
- mark the literals that need to be preserved for NVARCHAR2 columns as NVARCHAR2 literals by prefixing them with "n".
- set the mentioned property to activate the client side encoding mechanism with basically does a rough parsing of the statement and replaces all N-literals with U-literals. Undocumented U literals are similar to UNISTR calls. They encode non-ASCII characters with Unicode escape sequences. For example, n'€' (U+20AC) is encoded as u'\20AC'. As u'\20AC' contains only ASCII characters, it arrives to the database unchanged. The SQL parser recognizes the U-literals and converts them (unescapes them) to NVARCHAR2 constants before further SQL processing, such as INSERT.
