Finally! The RAID F Simulator is here ( and attachedd )
Dear All, Jesper from the Copenhagen Business School got this crazy idea some weeks ago, and with input from Michael Mller of Miracle A/S, it's my proud honor to present the World's first Oracle-based RAID-F Simulator. It's all fun and games, of course, and Jesper got inspired after reading James Morle's book. He simply copied the 20 pages or so about RAID and handed it to his boss and said that this was the knowledge he needed to understand the way Jesper was thinking about RAID! The boss did read it, and did understand it, and then Jesper went ahead with the RFS project just for fun. With the kind permission of Jared, I have attached it. So this is your Christmas gift from Jesper :-). Best regards, Mogens Spool raid.log Set pages 5 Set lines 132 Set trimspool on Set echo on /* RAID simulator == Introduction The purpose of the script is to have fun, while trying to get a better understanding of RAID-4 and RAID-5. James Morle writes in Scaling Oracle8i that one can play with XOR operations on a scientific calculator to see, that the redundancy in RAID-5 is sufficient to rebuild a crashed disk. After a few minutes using the Windows Calculator Jesper decided to automate the calculations by starting to write this script. Michael got hooked on the idea and made several improvements. The script simulates a RAID-4 system using an Oracle database. We are going to - Deal with physical data disks, a parity disk and one large logical disk. - Set up automatic maintenance of redundancy on the parity disk. - Format the disks and put some data on the logical volume. - See consequences of a disk crash followed by a successful disk rebuild. - Do some updates and check that the integrity is maintained. - Make a binary dump of everything to make it clear, what RAID is about. How to get started -- If you just want a quick tour then - Run this script with SQL*Plus against an Oracle9i database. - Open the logfile raid.log with your favourite editor. - Locate the test section (search for TESTING) and start reading. It is very simple plain SQL simulating a disk crash and a disk rebuild. If you want more then - Continue reading until you are working at the bit-level and/or - See how the simulation was set up in the first section. If you just can't get enough - Solve the exercises and write your own code. Difference Between RAID-4 and RAID-5 A RAID-4 system has a dedicated parity disk, which is maintained at block level like this: RAID-4 disk0 disk1 disk2 disk3 parity disk - - - - --- block 0block 1block 2block 3parity 1 block 4block 5block 6block 7parity 2 block 8block 9block 10 block 11 parity 3 block 12 block 13 block 14 block 15 parity 4 Etc. Considering the 4 physical data disks as one large logical volume, the Logical Volume Blocks can be mapped to the Physical Disk blocks like this: Logical Volume Address = 4 * Physical Disk Address + Disk Number From that statement we can derive: Disk Number = Mod(Logical Volume Address, 4) Physical Disk Address = Trunc(Logical Volume Address / 4) When doing a write to the logical volume we have to - Read the old data block - Read the old parity block - Write the new data block - Write the new parity block This cost of four physical I/Os for one logical write is known as the write penalty. If you are doing many random writes, then the parity disk becomes very hot. To avoid the bottleneck with one single very hot parity disk, RAID-5 stripes the parity blocks on all disks. Thus the write penalty is load balanced on more disks like this. RAID-5: disk0 disk1 disk2 disk3 disk4 - - - - - block 0block 1block 2block 3parity 1 block 4block 5block 6parity 2 block 7 block 8block 9parity 3 block 10 block 11 block 12 parity 4 block 13 block 14 block 15 Etc. NOTE: The write penalty still exists. In RAID-5 it is just load balanced. In order to keep things simple, this script simulates RAID-4. This simplifies calculations regarding where to physically find the data and parity blocks. The difference between RAID-4 and RAID-5 is only where the blocks are stored. There are no differences in the contents of the blocks. Thus we can learn how RAID-4 and RAID-5 works, without making it too difficult to deal with. If you really like complexity, then try to establish the 1:1 relationship between logical and physical blocks in RAID-5. Then migrate this script to support RAID-5. (Easier exercises can be found elsewhere in the script).

If you have one vendor to raise an issue with (not that you'd need to do that with Oracle of course!), it's a lot easier to get an answer without the finger pointing that can go on between vendors. Take the clusterware example - if you run into a problem running RAC on Sun with the Sun Cluster technology and Veritas owning the disk side, who you gonna call? GhostBusters, maybe! But if you're running RAC on Sun with Oracle's clusterware and ASM, it's a lot easier to determine who to call. Pete Controlling developers is like herding cats.

This is a radical departure. for those of you who dont know. Oracle claims that they will manage your disks for you. All you do is give Oracle some Raw Disks and Oracle will set up, and handle all your datafiles. All you do is look at logical tablespaces. It will also handle I/O balancing. How well does this work? Anyone test it with a SAN? 2. RAC Load Balancing. Oracle claims that you only need Oracle software from now on. They also claim that you can load balance multiple applications.

Hi,
Our main production
database was upgraded to Oracle 9.2.0.3 (64
bit) at the end of September 2003. Platform Solaris
64bit 5.8.
Since then the database
has "hanged" and had to be manually shutdown by killing processes and
re-started: -
(1) The first one involved the production of
numerous:ORA-04031: unable to allocate 26168 bytes of shared memory
("shared pool","unknown object","sga heap(1,0)","session param values")
,errors when users were logging and was linked by Oracle Support with bug
number 2921201
(2) Secondly,
the database raised an ORA-600 to the alert file:ORA-00600: internal error
code, arguments: [510], [0x380068B30], [shared pool], [], [], [], [], []
,followed by numerous messages:PMON failed to acquire latch, see PMON
dump
(3)
Thirdly, an:ORA-04031:
unable to allocate 16384 bytes of shared memory ("shared pool","unknown
object","sga heap(1,0)","trace buffer")was raised apparently caused by an
Oracle background processes dieing unexpectedly.
Should I upgrade to
9.2.0.4? None of the above problems seem to be fixed in
9.2.0.4!!!
Our database is a
hybrid between OLTP and Decision-Support with a relatively light load.
Anyone out there with
an unstable 9i database (we were more stable under 8.1.7)? Am I
alone??

transportable tablespaces need to be totally self-contained. everything that is being

Re: Hit Ratio
As a friendly reminder, when debunking myths, I suggest we keep sober and never go overboard. The recently popular formula to get an arbitrary hit ratio is not what a database in normal usage naturally gets. Unless a mischievous developer plays a prank, hit ratios are still useful to some extent in checking database health, although other indicators such as wait events should be given a greater weight.

Risk of knowing password hash value (Was: OEM permissions)
Hi, Gregory,
I only have access to Oracle 9.2 on my laptop. Here's my test. I have ORCL and
AUX1 databases, the latter created by RMAN DUPLICATE some time ago. I logon
AUX1 as SYSTEM. Set SYSTEM password hash value to the same as in ORCL. Create
link L to ORCL without password. Selecting from a table in ORCL @L (i.e. select
* from [EMAIL PROTECTED]) throws ORA-1017 invalid username/password.
Alternatively, I logon as SYS and create a procedure owned by SYSTEM, with one
line execute imediate('select count(*) from [EMAIL PROTECTED]'). When I execute
system.this procedure as SYS, I get ORA-1005 null password given. (I could
use DBMS_SYS_SQL but using the execute immediate trick obviates the need to
remember the syntax in that undocumented package).
If I use connect to current_user to create the link, I always get ORA-28030
Server encountered problems accessing LDAP directory service.
Could you try on your databases and show how you do it? As I said, this may be
a security problem. I'm just too ignorant of it and can't reproduce it for now.

Re: Exporting a partition with transport tablespace

No it's not. However, you could simply exchange the
partition with a table and then export the tablespace.
For instance,
ALTER TABLE HISTO_DOSSIEREXCHANGE PARTITION
part1 WITH TABLE HISTO_DOSSIER_part1;
Then export the tablespace. Make sure you do the
same for any local indexes, too.

The key word is EVERYTHING. Remember that all Oracle processes are sharing the same shared memory segment so they are all charged, or appear bigger in total size, because of that.

RE: Exporting a partition with transport tablespace
Title: RE: Exporting a partition with transport tablespace
Yes, my partitions are in separate tablespaces
so do I have to export all the tablespaces concerned ?
wich solution do you use ? each partition is over 8 Go so should I use common export command to backup only one tablespace ?

transportable tablespaces need to be totally self-contained. everything that is being transported has to be in that tablespace. it doesnt matter if its a different datafile.
you probably have your partitions in seperate tablespaces? or am i wrong?

I'm pretty sure Steve Adams agrees with you, since he co-presented on ASM at OracleWorld in San Fran. Not sure if he monitors this group actively or not, but I believe the presentation he did is loaded with all the other OracleWorld 2003 presentations so you can see what he said. 2. One point which makes a lot of sense to me, and it happens in a variety of places in 10g such as ASM and the RAC clusterware. If you have one vendor to raise an issue with (not that you'd need to do that with Oracle of course!), it's a lot easier to get an answer without the finger pointing that can go on between vendors. Take the clusterware example - if you run into a problem running RAC on Sun with the Sun Cluster technology and Veritas owning the disk side, who you gonna call? GhostBusters, maybe! But if you're running RAC on Sun with Oracle's clusterware and ASM, it's a lot easier to determine who to call. Pete Controlling developers is like herding cats.

For example, ASM offers the ability to add disks to a stripe without needing to redistribute(reload) the entire stripeset. A (bug-free) ASM product looks very very impressive to me.

The datafile for our rollback segments gre huge because of an improper setting. Even setting optimal and shrink, etc., won't help because the segments are scattered.

stress tests for a scale to 30,000 users
My estimate right now is about a 500GB instance(but could grow). There are several complexities. 1. high transaction system, but also will have alot of long running queries 2. We deliver data daily and rebuild large parts of the database nightly with loads. Im not certain I have the window to analyze every index or get histograms on all the tables. There are VERY large data loads and deliveries. Data has to be delivered by a certain time and we get data feeds from other groups. I cannot control when we recieve data to load. 3. We will not be actively managing the production server. Its going to be delivered as an off the shelf product. I do not know what statistics ill be allowed to have for security reasons(this is not govenment stuff so dont worry about what I say). Its up to the client. 4. We are using web server level connection pooling so tracing isnt very useful. Im essentially the lone performance guy on the team. Ive never done a scale up this large, or with this many complexities. We just managed to convince them to use bind variables... but they haven't been implemented yet. Im having trouble getting accurate test cases. This is what I am 'attempting' to do at first. Please let me know if my approach is accurate. 1. Find out which queries will be run the most. Are there things people will do in the mornings, but not in the afternoon(so far its 'dunno'). 2. Hopefully, I can get a hold of either the use cases or 'preferebly' test cases, so we can design our stress tests around actual user processes. All they are doing now is opening up 50+ users and running queries in loops. What other approach should I take to get started.

RE: Exporting a partition with transport tablespace
Title: Exporting a partition with transport tablespace
You could create new table in
transportable tablespace, exchange data with the partition you want to export, move
transportable tablespace file to the destination system, exchange data back
from the table into desired partition.

Re: Rollback datafile size
Mike, When an RBS is taken offline, the undo information is not transfered to another segment, hence the need to perform these actions at a quiet time. When an rbs is taken offline, all transactions currently using the rbs are allowed to complete (either commit or rollback). As these transactions are processing, the status of the segment is 'Pending Offline'. Once the tx is complete, the status will change to 'Offline'. If a query is running and needs undo entries from an offline (including pending) rbs, it will fail with a 1555. Daniel Michael Milligan wrote: Daniel, Thank-you very much for your clear answer.

you can also do the following: 1. create table as and copy just the records you want to keep. 2.

Otherwise, it may be faster to do a CREATE TABLE AS SELECT with nologging, parallel, blahblah, to select all the lines you want to keep, truncate the table, and INSERT ... SELECT back in the same manner. Better to have your database in restricted mode then. I used this method in a (euro-zone) bank to delete everything but CHF, GBP and the like when we waved farewell to national currencies, worked pretty efficiently. -- Regards, Stephane Faroult Oriole Software -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Stephane Faroult INET: [EMAIL PROTECTED] Fat City Network Services-- 858-538-5051 http://www.fatcity.com San Diego, California-- Mailing list and web hosting services - To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).

Re: Risk of knowing password hash value (Was: OEM permissions)
Environment:
DB1: RH 8.0 with Oracle EE 9.2.0.4
DB2: Win2k SP3 with Oracle EE 9.2.0.1
SYSTEM user on each database initially have different passwords.
It goes something like this:
DB1:
select password from dba_users where username = 'SYSTEM';
Let's say the result is 'AC424SDK4398'
DB2:
Logon to DB2 as SYSTEM.
alter user SYSTEM identified by values 'AC424SDK4398';
create database link systemlink using 'DB1';
Logout, and log back on to DB2 as SYSTEM.
select count(*) from [EMAIL PROTECTED];
Works for me in this environment. DB2 is compromised.

Take the clusterware example - if you run into a problem running RAC on Sun with the Sun Cluster technology and Veritas owning the disk side, who you gonna call? GhostBusters, maybe! But if you're running RAC on Sun with Oracle's clusterware and ASM, it's a lot easier to determine who to call. Pete Controlling developers is like herding cats.

sql_trace when using middle tier connection pooling
Our middle tier opens several dedicated connections. SQL statements are issued through these dedicated connections. If Im running a stress test and I want to trace... what is the best method to use? Just use a logon trigger and trace every session? then dig through it to look at the top sql(which would be indicated by statspack). any other suggestions would be helpful. I really have no control over the middle tier or front end.

That works also. I guess it really depends on which one is faster, and that is dependent on what % of the data you are trying to remove, and how big the whole thing is.

Re: TNSPING VS. REGULAR PING..! WHY SUCH A DIFFERENCE
Paul mentioned a few reasons for this. Another is that a ping does not get past the NIC. The ping is answered by software running on the card. You may have noticed at times that a ping is not a reliable method for determining if a server is still functioning. The OS can crash, but the NIC still responds to a ping. Tnsping on the other hand must get a response from Oracle Net service or daemon running on the server, a much longer path as Paul pointed out.

Re: Risk of knowing password hash value (Was: OEM permissions)
It doesn't matter which account I logged into DB2 with, as
long as that account has privileges to read DBA_USERS.
SYSTEM was used simply because it was the only account
on the database that could be logged into remotely, so
my test could be run without switching between machines.
If I had granted SELECT_CATALOG_ROLE to scott, I could
have logged in as SCOTT and done the same.
Jared
PS. Forgot this in private post to Yong: The password is
cached, I assume in the PGA. This doesn't work without
reconnecting. Logging out isn't strictly necessary, but
the way my shell is setup, it takes quite a few less keystrokes
to logout/logon than the type 'connect system/[EMAIL PROTECTED]'.

Sent by: [EMAIL PROTECTED] .com 12/21/2003 09:29 PM Please respond to ORACLE-L Hi, Our main production database was upgraded to Oracle 9.2.0.3 (64 bit) at the end of September 2003. Platform Solaris 64bit 5.8. Since then the database has hanged and had to be manually shutdown by killing processes and re-started: - (1) The first one involved the production of numerous: ORA-04031: unable to allocate 26168 bytes of shared memory (shared pool,unknown object,sga heap(1,0),session param values) , errors when users were logging and was linked by Oracle Support with bug number 2921201 (2) Secondly, the database raised an ORA-600 to the alert file: ORA-00600: internal error code, arguments: [510], [0x380068B30], [shared pool], [], [], [], [], [] , followed by numerous messages: PMON failed to acquire latch, see PMON dump ? (3) Thirdly, an: ORA-04031: unable to allocate 16384 bytes of shared memory (shared pool,unknown object,sga heap(1,0),trace buffer) was raised apparently caused by an Oracle background processes dieing unexpectedly. Should I upgrade to 9.2.0.4? None of the above problems seem to be fixed in 9.2.0.4!!! Our database is a hybrid between OLTP and Decision-Support with a relatively light load. Anyone out there with an unstable 9i database (we were more stable under 8.1.7)? Am I alone??

Re: Risk of knowing password hash value (Was: OEM permissions)
On RH 8.0 Oracle 9.2.0.4: F894844C34402B67 It is required that a password for a particular users always hashes to the same value, regardless of platform or Oracle version. This has been true for as long as I have used oracle: since 7.0.13. If not, export/import would not be able to recreate users, and database links without a password would not work. Good reason to protect DBA_USERS, no? Jared On Mon, 2003-12-22 at 20:44, Michael Thomas wrote: Hi, Okay. I'm almost a believer of this as a problem.

Re: Risk of knowing password hash value (Was: OEM permissions)
Yes, I misunderstood.
Once I change the password, I can no longer connect to the account.
My hasty little test was missing an important condition: I should
have pretended I didn't know the password to the other database,
which would prevent me from logging back on exploiting the db link.
Wonder if there's a way around it though?
I spent a few minutes looking for a way around that problem, and
couldn't find one. Oracle may have covered the bases on this, they've
had a few years to perfect it.

Hey, you're working late!
OK. I think you misunderstood. I know you take SYSTEM as an example user. Let's
say it's SCOTT who has select_catalog_role. If you login to your own database
as SCOTT and change his password hash value, you don't know the clear text
password any more. How can you log out and log back in as SCOTT? That's why I
ask if you can use the link without logging out after changing the password?

It doesn't matter which account I logged into DB2 with, as
long as that account has privileges to read DBA_USERS.
SYSTEM was used simply because it was the only account
on the database that could be logged into remotely, so
my test could be run without switching between machines.
If I had granted SELECT_CATALOG_ROLE to scott, I could
have logged in as SCOTT and done the same.

SYSTEM user on each database initially have different passwords.
It goes something like this:
DB1:
select password from dba_users where username = 'SYSTEM';
Let's say the result is 'AC424SDK4398'
DB2:
Logon to DB2 as SYSTEM.
alter user SYSTEM identified by values 'AC424SDK4398';
create database link systemlink using 'DB1';
Logout, and log back on to DB2 as SYSTEM.
select count(*) from [EMAIL PROTECTED];
Works for me in this environment. DB2 is compromised.

Could you try on your databases and show how you do it? As I said, this
