Best way to move the modified data after upgrade
Title: Best way to move the modified data after upgrade Kindly read the whole scenario and let me know your views. (1) What we have ? Three db instances on the same machine. Two of the instances are on 8.1.7.4 One of the instance is on 8.1.6.0 Oracle as well as O/S is running on 32-bit. Database is running in archivelog mode. The current box is Sun SPARK E6500. Use BCV backup solutions with Veritas NetBackup for tape integration. The production server (E6500) and the backup server both are physically located in Ohio. The total db size is 1.5 TB. (2) What we are going to do ? Migrate to a new E12K server. Migrate all three instances to 9.2.0.4 Install Oracle on top of 64-bit Sun Solaris 2.9 version. Install 64-bit Oracle software on top of it. The new server is supposed to be located in Arizona. (3) How we are going to do ? Shut down all three instances on the production server. Take the backup on the backup server. Copy the data on to tape. Ship the tapes over to Arizona where the new E12K box resides. Copy all the data from tape on to the new E12K. Upgrade all three instances on the new E12K as mentioned above on DAY1. Back up all the data locally. Now it takes around 2 days to ship all the tapes are shipped to Arizona and then copy the data over to new E12K. During this time the users are still accessing the production server in Mason. Also the etl jobs are updating/inserting/deleting data from this server in those two days. (4) Whether this is possible ? Now lets say we want to apply just the changed data from DAY1 till DAY3 is there any way I can do it ? The only other option we have at this moment is to run all the jobs against the newly configured E12K. (I guess the answer is NO, but just wanted to confirm with u all) -- Thanks, Chetan

Tom ,
I set REMOTE_LOGIN_PASSWORDFILE = EXCLUSIVE, gave the same name to the pw
file as suggested by you (though it was not mentioned anyewhere) and tried;
but still it's not working.
I can't figure out what can be the problem.

Subject: RE: SYSDBA privilege with ORAPWD utility
Chetan,
The NAME of the password file should be:
PWD{sidname}.ORA.
For example, if your Oracle Sid name is SB815, your password file should
be
named
PWDSB815.ORA
On NT boxes, upper/lower case of the file name does not matter.
Hope this helps.

Hi List ,
I have Oracle 8.1.5 server on Win 2K machine.
When I try to connect as SYSDBA using SYS account from a remote machine it
says ORA-01017: invalid username/password; logon denied. Then I created
a
password file using ORAPWD utility and granted SYS and WIP (a newly
created
schema) the SYSDBA privilege. I also ensured that
REMOTE_LOGIN_PASSWORDFILE
is set to TRUE, but still I can not connect as SYSDBA.
Following are the steps which I took.
Step 1. Created a password file as followed :
D:\Oracle\Ora815\BINcd ..\dbs
D:\Oracle\Ora815\DBSorapwd file=orapwsb815 password=oracle8i
entries=30
Step 2. Grant SYS user the SYSDBA privilege by the following method

Re:Oracle Performance Tuning steps
Dick , Thanks a ton for ur feedback. I ran UTLBSTAT/UTLESTAT and found out that the problem was with memory. Then I went and queried V$SGASTAT, V$SQLAREA, V$SQLTEXT. Can u tell me if there can be any other problems ? I found out later that there were some indexes added afterwards. Thanks nyways. Chetan [EMAIL PROTECTED] wrote: Chetan,First questions, What changed? Did someone add/delete an index? Was therean oversized data load done? When were the statistics, if present, lastcomputed? Has a new program/application been added to the server? Did a memorybank go offline? Did a disk interface card go offline?I use HP's HP-UX boxes as well, except most of my DB's are 10 times largerthen yours. Just about everytime something like that happens, especially all ofa sudden, one of those questions is the cause. The last item I'd go lookingfor, have only had one instance of it so far, is a unrestricted user whoreleased "the query from HELL" into the database as a "one time requirement". If you can find him/her I've a used gallows rope is still here, one usage only.Dick GouletReply Separator____Author: Chetan <ORACHETAN@YAH! ! OO.COM>Date: 6/26/2002 2:18 AMHi guys ,Need some help.
