Exadata database server on solaris

Is Solaris OS running on Exadata DB server is of big endian or little endian? Need this answer to decide on endian conversion requirement while migrating to exadata.

Hi Tycho,
i don' think he has a solaris exadata. he just want's to know if he gets one whether he can migrate direct big endian to big endian. Unfortunately endianness is a proerly of the chip architecture and not of the OS hence intel x86 chips have always been little endian unlike any of the risc architecture chips.
I think the only big endian intel chips were probably the xscale, i860 Intel i860 - Wikipedia, the free encyclopedia ,i960 and itaniums.
See Endianness - Wikipedia, the free encyclopedia for more endian goodness

Significant difference in response times for same query running on Windows client vs database server

I have a query which is taking a long time to return the results using the Oracle client.
When I run this query on our database server (Unix/Solaris) it completes in 80 seconds.
When I run the same query on a Windows client it completes in 47 minutes.
Ideally I would like to get a response time equivalent on the Windows client to what I get when running this on the database server.
In both cases the query plans are the same.
The query and plan is shown below :
{code}
SQL> explain plan
2 set statement_id = 'SLOW'
3 for
4 SELECT DISTINCT /*+ FIRST_ROWS(503) */ objecttype.id_object
5 FROM documents objecttype WHERE objecttype.id_type_definition = 'duotA9'
6 ;
Explained.
SQL> select * from table(dbms_xplan.display('PLAN_TABLE','SLOW','TYPICAL'));
PLAN_TABLE_OUTPUT
| Id | Operation          | Name      | Rows | Bytes |TempSpc| Cost (%CPU)|
|   0 | SELECT STATEMENT   |           | 2852K|    46M|       | 69851   (1)|
|   1 | HASH UNIQUE       |           | 2852K|    46M|   153M| 69851   (1)|
|* 2 |   TABLE ACCESS FULL| DOCUMENTS | 2852K|    46M|       | 54063   (1)|
{code}
Are there are configuration changes that can be done on the Oracle client or database to improve the response times for the query when it is running from the client?
The version on the database server is 10.2.0.1.0
The version of the oracle client is also 10.2.0.1.0
I am happy to provide any further information if required.
Thank you in advance.

I have a query which is taking a long time to return the results using the Oracle client.
When I run this query on our database server (Unix/Solaris) it completes in 80 seconds.
When I run the same query on a Windows client it completes in 47 minutes.
There are NO queries that 'run' on a client. Queries ALWAYS run within the database server.
A client can choose when to FETCH query results. In sql developer (or toad) I can choose to get 10 rows at a time. Until I choose to get the next set of 10 rows NO rows will be returned from the server to the client; That query might NEVER complete.
You may get the same results depending on the client you are using. Post your question in a forum for whatever client you are using.

Sqlplus to connect to remote oracle database server

Hi,
I have oracle 10g database server on solaris 10 and I usually connect using my solaris account and run sqlplus on the server itself. this works !
I have downloaded and installed oracle instant client for solaris 64 and I can run sqlplus command but I am confused on what should be the syntax on the command to connect to remote solaris 10 databse server where I have both system and oracle account.
I have tried sqlplus help but still I could not get correct sysntax which could be used to authenticate myself to oracle server.
I tried
sqlplus user@hostname:1512/SID
then it asked for password but when I typed password and pressed enter, it gave some error
but it again asked for username so I type user@SID and then password prompt - typed password and this works!
so I don't understand what should be the correct syntax so that in the first attempt only I am able to connect.
if possible please give the exact command with realworld examples,(I have tried with sqlplus -help already)
Thanks in advance.

wonder what if I did not have tnsnames.ora on the client machine, how will be the syntax?You generally need (or at least strongly want) a tnsnames.ora file on the client machine.
- You could configure Oracle Internet Directory and let that product provide TNS alias resolution for the organization (similar to setting up DNS for a local network).
- Many tools (I haven't personally tried SQL*Plus and it may be version dependent) allow you to specify the entire TNS alias from the tnsnames.ora file (i.e. everything after the abcd.domain.com = entry) but that is hugely cumbersome to type
- Depending on the Oracle client version, the sqlnet.ora file, the complexity of your configuration (i.e. if you are trying to use more sophisticated features like failover), you may be able to use the EZConnect syntax
sqlplus username/password@host:port:SID/service_nameWhere host is the server that the database is running on, port is the port the listener is listening on (i.e. 1521 by default) and SID/service_name is the SID or service name you're trying to connect to.

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.

Replicate some tables from local database server to Remote database sever

how can i replicate some tables from local database server(Oracle 8.1.7 on windows 2000 server) to a remote database server(Oracle 8.1.7 on Sun Solaris)
whenever there is some insertion or updation on the table of base(main) database it should get updated to the remote database server
or
on time base for example: every 2 hours
please help me!!!!

It all depends on waht you are going to do with the data on the remote.
if tehre are no updates there, creating a simple materialized view on the remote to pull it's data from the local should suffice.
If there are updates on the remote, you will more than likely want to look into either Multi-master replication, or updatable materialized views.

How to get database server IP address?

I have Php backend website, where i have a text area to run sql queries against underlying Oracle 10g/solaris database.
I have ca 10 such Backend web sites, and 10 underlying Oracle databases for each website. Each Backend website lives different computer than Backend Php webserver.
I have problems to understand what is the database IP of the Backend website.
Can i query it?
My example wrong queries:
I know that underlying database in this example is with IP "192.168.2.165", but i canät manage to query that out, see:
This is not the database IP:
select UTL_INADDR.GET_HOST_ADDRESS from dual--127.0.0.1
This is some mysterical computer name that i cant ping:
select UTL_INADDR.GET_HOST_NAME from dual;--tar_071_z
This is wrong IP:
select UTL_INADDR.GET_HOST_ADDRESS('tar_071_z') from dual;--127.0.0.1
Wrong:
select UTL_INADDR.GET_HOST_ADDRESS( UTL_INADDR.GET_HOST_NAME ) from dual;--127.0.0.1
I don't know what IP is that:
select sys_context('USERENV','IP_ADDRESS') from dual;--192.168.2.160

Each database should have a unique name, use that instead.

Connecting to SQL Server from Solaris using Perl & Oracle.

Hey All,
Using the DBI.pm provided by the default Perl package that comes integrated with Oracle server, I am being able to connect to the Oracle database through Perl.
But is there a way I can connect to SQL Server through Perl using any package provided by Oracle like ODBC or something else (on Solaris)
I am using following version of Oracle server on Solaris 10
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
TIA
Parag

The problem is I cannot install any third party package but I found something. Have a look at this:
bash-3.00$ pwd
/opt/oracle/product/10.2.0.4.0/perl/lib/site_perl/5.8.3/sun4-solaris-thread-multi/Win32
bash-3.00$ ls -l
total 10
-rwxr-xr-x 1 oracle dba 4532 Jul 7 2004 DBIODBC.pm
bash-3.00$
Will explore more and keep you all posted.
Cheers,
Parag

CPU & Memory allocation in Exadata Database

Hi All,
We are using Exadata 1/8th Rack which is having 256 GB memory and 12 cores on each Database server.
Our requirement is to create 15 databases out of which 10 are standalone and 5 are clustered database.
Now we are concerned about how the memory and cpu will be done for all these databases. I know we should not allocate more than 75% of total memory and cpu on the server. But don't know how much sga and pga I should allocate to each db and what is the mathematics here.
Kindly let us know if any one has done same kind of configuration earlier or any best practices to resolve such issues.
Also, please suggest if instance caging will be helpful here, please share detail if anyone has experience instance caging on exadata.
Your assistance is highly appreciated.
Thanks,
Vineet

Hi Vineet,
Some quick math:
With 10 standalone and 5 2-node clustered databases, that would average to 10 instances per database server. Again going by straight averages, using 75% of total memory and CPU, that would leave you with an average of 19GB of memory and 0.9 CPU cores per instance. It's a lot of instances but definitely not impossible.
I'd suggest looking at where the databases are sitting now: assuming they're Oracle databases, how much SGA and PGA do they have allocated now? What are the advisers telling you about optimal sizes?
With this many instances, instance caging doesn't really make sense: you'd only have a single CPU core for each instance. Again here, looking at the existing workload is a good place to start. How many CPU cores are they using (typical/peak) already? Would you expect to use more than 75% of CPU capacity during peak usage periods? If you are, one option to look from the CPU-management side would be the MAX_UTILIZATION_LIMIT, though the main issue is that, as for instance caging, it only refers to a single instance.
And don't ignore I/O capacity. Even though X4s have a lot of flash, it doesn't hurt to get statistics for read and write volumes on your databases, and see how they compare to Exadata specs.
And lastly, there's no true substitute for real testing. If you're using 12c, RAT consolidated replay is very nice, but perhaps you can re-purpose application-level testing infrastructure to test on Exadata as well?
There are a lot of good Exadata and general Oracle consolidation presentations from various conferences floating around. A Google search will show a few, or you may even want to sign up for virtual attendance for one of the major Oracle conferences to get access to the slides and papers.
HTH!

So far no proper help from ORACLE yet nor i don't beleive going in right direction.
I beleive something to do with listener.ora and tnsnames.ora file. But don't know what is the exact issue.

How can I install Oracle Database 10g for Solaries (SPARC) from the console

Dear Forum Members,
In my office, I have to installed Oracle Database 10g for Solaries (SPARC). But I have to do it without DISPLAY Monitor.Is it possible install it by remote login to this server using response file (silent mode) or something like that?
If yes. Then How?
If anyone have the exact solution, then I need your feedback. I shall wait for your reply.
Thanks
Aungshuman Paul

There are 2 possible ways to accomplish this.
First,
Silent installation

How to install Oracle software remotely?
Remote Software Installation Steps: (For Solaris only)
If you want to install Oracle Software remotely, you should perform the following steps. These steps are applicable only if your source and target machine are running Unix.
For example, you can install Oracle Software from your home from Washington, DC to a target source in California.
1. Pick your source server or machine for remote installation.
2. Check that your CD is in your source CD-ROM drive.
3. On the target machine, find your target machine name with the output of the /usr/bin/hostname
4. On the source machine, login as a user.
5. On the source machine, enable client access: % /usr/openwin/bin/xhost + target-machine-name
6. Become root user by typing: su (dont use -)
7. Check that Volume Manger is running. # ps ef |grep vold (if you see an entry that contains /usr/sbin/vold, Volume Manager is running. Then skip to Step 10.
8. If not then do the following: # mkdir p /cdrom/your-cd-file-name
9. # mount F hsfs r cdrom-device /cdrom/your-cd-file-name
10. Add the following line to your /etc/dfs/dfstab file: # share F nfs o ro /cdrom/your-cd-file-name
11. Verify whether your source machine is an NFS server: # ps ef | grep nfsd
12. If you see an entry that contains /use/lib/nfs/nfsd a 16, then nfsd is running and skip to Step 16.
13. If nfsd is running, then type: # /usr/sbin/shareall
14. If nfsd is not running, then start nfsd by typing: # /etc/init.d/nfs.server start
15. Verify whether your source machine is an NFS server again by typing: # ps ef | grep nfsd
16. Make sure your source machine is exporting your product directory by typing: # /usr/sbin/dfshares
17. Now, log in to the target machine by type: # rlogin target-machine-name l user (not root)
18. Then log in as the root user by typing: # su
19. Go to the source machine by typing: # cd /net/source-machine/cdrom/your-cd-file-name ,then Skip to 24.
20. If you cannot change to that directory in Step 19 and you do not have an auto-mounter on your network, then create amount point by typing the following commands.
21. # mkdir /remote_products
22. # /usr/sbin/mount F nfs r source-machine:/cdrom/your-cd-file-name /remote_products
23. # cd /remote_products
24. Redirect the target machine display to source machine by typing: # DISPLAY=source-machine:0; export DISPLAY (if you use a Bourne or Korn shell).
25. Start the Web Start Installer by typing: # ./installer (or whatever the installer name program is).

Exadata Database Machine two node servers reboot

Hi,
Good morning to all.
Would like to seek help in regards the problem that I have encountered and an error in running exachk on exadata database machine. The problem I have encountered first is on Database Server node1 and node2, both server nodes when powered up and while OS OLinux is on boot process in the middle of loading devices for OLinux to recognize, the kernel panic appeared and the system automatically reboots.
I tried to copy the exachk file on storage and run exachk under user root but the error message appeared it advises me to run it on compute node.
command to run exachk under root server.
# ./exachk
For your kind further advise
Genesis

Hello Genesis,
If your database servers are unable to boot at all, I'd suggest addressing that part first. This is really Oracle Supprot SR territory, but I'll try and offer a few suggestions. Do you have the output on the kernel panic available? One way of getting this would be to log onto the ILOM console, and capturing a screenshot of the window while the kernel panic output is on the screen. Knowing which part of the kernel code the panic is happening may help identify a known issue with a simple fix. Note 1538068.1 talks about an issue with LVM snapshots, for example, and also has instructions on how to do boot into a diagnostic image. But again, this type of issue is best dealt with on an Oracle service request.
exachk itself doesn't run directly from storage servers, so hence the errors you see; it needs to be launched from a database server.
HTH!

Drawbacks of Autostart of Database on Linux/Solaris ?

Hi,
i have a script to autostart database on Linux/solaris, its working perfactly,
but i heared that its always preferrable to start database manually on LInux/Solaris.
so what is the drawbacks of Autostart?
another thisng is that how to autostart RAC DB with ASM on Linux/Solaris?

But one issue can be if storage is in use and disks for some reason are not automounted on reboot then of course database autostart is not prefferable.
If server opsystem is patched (new kernel install, some other changes), then sysadmin could want to just startup server and look is it working, he don't need all those databases to startup. But again it heavely depends what kind of activities sysadmin is performing.
But if everything is mounted on startup, then autostartup of database is just easier for us. for example sudden reboot of server will not disturb us. Databases will be autostarted.
And for high-availability and for all those SLA things - autostartup will reduce downtime.

Performance issue with database server

Hello,
We have installed ECC 6.0 on HP UX 11.23 OS with Oracle as database.
We have cluster environment in our production severs.
One server as DB-CI installed and other as Dialogue Instance installed.
After installation, the dialogue instance (Application server))works fine but if we login into DB server and execute any t-code It takes too much time or just stuck.
and after that if I go to application and execute that t-code it works fine and after that if I go to database and execute that t-code now even in DB it works fine.
Kindly guide me.
Thanks,
Chandresh Pranami.

Hi Chandresh,
Check below things for your Database server.
SM50 - Workprocess status busy or wait
ST04 - Data buffer hit ratio
SM37 - Any background job running there.
Normally even if you are login through a diffrent app server the database side execution will happen in db server only.Application server will do the execution but the data read and to be updated will happen in db server only.When the sql request will go to db server may select update..types of sql then it willalways will be processed by db server.
So there will be lot of load already thereIg you execute your work here it will take more time because more load for the application will be there.
Regards
Ashok
