Perfstat user in 4.6C/oracle9i
Dear all,
We found that there is a oracle user perfstat in our 4.6C/oracle9i/solaris landscape.
But in our hpux system where we have installed installed 4.6C/oracle10g, we could not find the user perfstat.
Can you please explain
1.what is the use of perfstat user in oracle?
2. why it is not available in oracle 10g/sap4.6c?
3. Do we need to recreate the same user manually in oracle10g/sap4.6C?
Pl clarify
Thanks
Senthil
Hello Senthil,
the PERFSTAT user is normally added, if you install STATSPACK on oracle. This is a package for Oracle 9i (and as well as for Oracle 10g, if you don't have the Oracle Database Diagnostic Pack).
STATSPACK is used to take performance snapshots on oracle databases to analyze load situations / performance issues.
If you install SAP on Oracle 10g you automatically have the "Oracle Database Diagnostic Pack" and you can use the AWR instead of the STATSPACK - so no STATSPACK is needed (and no PERFSTAT user is installed).
So you don't need to add this user manually.
For more information about STATSPACK - take a look at sapnote #717484
Regards
Stefan

Error in Droping PERFSTAT User
Hi All,
I'm getting the following two error messages while dropping the PERFSTAT schema & the tables.
The oracle version is 9.2.0.1.0 & it is running on SUN SOLARIS 9.
I've logged in as sys dba & executed the script "SPDROP.sql" to drop the PERFSTAT schema. all the tables, views & synonyms dropped successfully.
But the PERFSTAT user didn't dropped. I can still see the user in DBA_USERS.
Rather I got the two error messages:
ORA-00604 error occurred at recursive SQL level 1
ORA-04098 trigger 'SYS.DDLTRIGGER' is invalid & failed revalidation
Can any one help if I'm doing the wrong thing....
Else is there any other procedure to drop the PERFSTAT schema.
SunilYes
This trigger was created to capture the DDL operations along with a trigger to capture the logon & logoff information on the database from the front end. Which was not allowing me to drop the PERFSTAT schema. As these triggers were updating few tables in the PERFSTA schema. After disabling the triggers well I can able to drop & recreate the PERFSAT.
Thnx for the inputs

User creating problem in oracle9i lite.

Database : Oracle 9.0.1.1.1
Hi
i'm logging into mobile server control center as administrator. And i create users for the applications. But when i try to list the users, there is no user listed except the administrator. Could anyone help me about this?Ramesh,
This looks like it might be a Java class mismatch error. Do you have multiple versions of Java installed on your machine? If so, you may want to keep one version and remove the rest.
If you're already running just one version, you may want to check the registry and classpath for references to multiple Java versions, or version that no longer exist.
Please let me know if you have additional questions.

View list of tables created by user
How can I see a list of tables that I, as a user, have created in Oracle9i (assuming that I am just a user and not an administrator)?
Thanks,
Pattie'select table_name from user_tables' will give you list of all the tables you own.
'select object_name,object_type from user_objects' will show you all objects (tables,indexes,views,synonyms,procedures,triggers etc) that you own. -

Hi!
I'm interested in knowing a little more about Oracle9i Clickstream Intelligence.
I've seen in Oracle9i Clickstream Intelligence User Guide and in Oracle9i Clickstream Intelligence Administrator's Guide, a reference to
Oracle9i Clickstream Intelligence Data Model Reference, but I can't seem to find it.
Can anyone tell me where can I find this doc?
Thanks in advance,

Apologies for the delayed response.

Hi all,
I have prepared a logical dataguard on two local systems. My oracle version is 9i and linux version is Entreprise Linux 3.0.
Today when i tried to execute spcreate.sql on the primary database it had thrown some errors in my secondary database.
Kindly look at the following output from my secondary database:-
SQL> select applied_scn,newest_scn from dba_logstdby_progress;
APPLIED_SCN NEWEST_SCN
270084 272644
SQL> SELECT XIDUSN, XIDSLT, XIDSQN FROM DBA_LOGSTDBY_EVENTS

EVENT
STATUS_CODE
STATUS
grant select on STATS$V_$SQLXS to PERFSTAT
942
ORA-00942: table or view does not exist
from the above errors i have found out that a particular transaction is unable to replicate in my standby database and i skipped the transaction. But still after skipping the transaction applied_scn in the dba_logstdby_progress is moving only by 3 each time I skip a transaction . So it won'' t be possible for me to skip each and every transaction.
Kindly let me another way of skipping the rest of transactions which are causing halt in the replication.
Also I am unable to find out how the script executed from the sys user can be replicated on logical database as sys comes in unsupported users in logical datagurad.
Is there any way I can execute a script on primary database which won't reflect on secondary database.
thanks in advance.Hi Yoann,
Commands you provided for skipping perfstat schema worked on logical database .
Now i m executing spcreate.sql on secondary database it gives following errors after i have specified the perfstat password,default tablespace for perfstat as 'perfstat' and temporary tablespace for perfstat as 'temp' and datafile contained in perfstat tablespace is 150 MB in size.
spcreate worked fine on primary but is giving errors in the end in secondary.Any suggestions about this:-

It is possible to drop objects manually, but what spdrop is doing is calling spdtab, which drop all perfstat objects and then drop user.
Can you run select object_name, object_type from dba_objects where owner='PERFSTAT'? -

Create statspack report using sql*developer
Hello,
While connecting with PERFSTAT user I can not create statspack report using SQL*Developer:
@?/rdbms/admin/awrrpt
Error starting at line 1 in command:
@?/rdbms/admin/awrrpt
Error report:
Unable to open file: "?/rdbms/admin/awrrpt.sql"
Actually, my problem or question is that how can PERFSTAT user can generate statspack reports from a Client side. What is the other way a non-dba can see the snapshots histroy and generate report (by using perfstat user ) while joing tables or using views?
Thanks a lot.
Best RegardsHi,
for awr reports @?/rdbms/admin/awrrpt (you need EE+Diagnostic Pack) there is a solution.
Grant execute dbms_workload_repository to <user>;
Grant select_catalog_role to <user>;
get all SNAP_IDs
SELECT TO_CHAR(s.startup_time,'YYYY.MM.DD HH24:MI:SS') INSTART_FMT,
di.instance_name INST_NAME,
di.db_name DB_NAME,
s.snap_id SNAP_ID,
TO_CHAR(s.end_interval_time,'YYYY.MM.DD HH24:MI:SS') SNAPDAT,
s.snap_level LVL
FROM dba_hist_snapshot s,
dba_hist_database_instance di
WHERE di.dbid = s.dbid
AND di.instance_number = s.instance_number
AND Di.Startup_Time = S.Startup_Time
ORDER BY snap_id desc;
Select * From Table(Sys.Dbms_Workload_Repository.Awr_Report_Html(DBID, 1, BEGIN_SNAP_ID, END_SNAP_ID));
For statspack i don't know a solutuion. I think the best idea is, create a job to make the statspack report on the server side and access it via external tables or mail them forward to you.
Best regards

Problems and solutions for 9i DB R2 install on Redhat Linux AS 2.1
Installing 9iDB R2 9.2.0.1.0 on Redhat Linux Advanced Server 2.1 (aka Redhat Enterprise Linux (AS))
and applying patchset 2 (9.2.0.3.0)
This is a certified platform but I hit many problems getting the install to work. Here are the problems I hit and how I solved them.
Note: This is not intended to be a install for dummies but just an account of all my problems and how I overcame them. I spent 10 hours on this certified install (mostly looking for solutions to the problems I was having)
I had a Intel Pentium 3 with 512 Meg RAM. (test machine)
1. Install Redhat Linux
2. Install Sun JDK 1.3.1 (this is not actually required for this install. I installed it as I was planning to install 9iAS after this)
3. Install binutils-2.11.90.0.8-13 (also not required. I installed it for 9iAS)
All other components were ok on my Redhat Linux install (i.e. kernel version, glibc)
4. Create oracle user with dba group
5. Create oracle home and oracle base directories. Ensure these are owned by oracle with rwx
6. Set kernel parameters and make sure that they are initialized every startup:
I managed to locate this script in the Redhat document called
"Deploying Oracle9iTM on Red Hat Enterprise Linux AS"
create a file called oracle.sh in /etc and give it execute permissions
oracle.sh
#!/bin/bash
# configures kernel and system parameters for Oracle9i R2
# File handles
echo 65536 > /proc/sys/fs/file-max
ulimit -n 65536
# Shared memory
# The default SHMMAX value is too low and likely to cause a failure during
# database creation. SHMMAX should be equal to half of your system's physical
# RAM.
# The default is for 512 MB of RAM. Replace the default value as appropriate
# for the amount of memory in your system, i.e.,
# 512 MB : 268435456
# 1 GB : 536870912
# 2 GB : 1073741824
# 4 GB : 2147483648
echo 268435456 > /proc/sys/kernel/shmmax
# It is generally safe to leave these next two values as they are
echo 4096 > /proc/sys/kernel/shmmni
echo 2097152 > /proc/sys/kernel/shmall
# Semaphores
echo 250 32000 100 128 > /proc/sys/kernel/sem
# Sockets
echo 1024 65000 > /proc/sys/net/ipv4/ip_local_port_range
# Processes
ulimit -u 16384
----EOF---------
then...
# chmod +x /etc/oracle.sh # make executable
# . /etc/oracle.sh # apply changes now
edit /etc/rc.local to ensure this is run on startup
append to /etc/rc.local
# configure system for Oracle9i R2
bash /etc/oracle.sh
--------EOF--------------------
7. create a generic oracle environment setup script for all users to run
create the file /etc/profile.d/oracleenv.sh
be sure to change the variables to your environment (ORACLE_BASE, ORACLE_HOME and ORACLE_SID)
oracleenv.sh
# Configures the user's environment for Oracle9i R2
ORACLE_BASE=/opt/oracle
ORACLE_HOME=$ORACLE_BASE/product/9.2.0.1.0
ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data
ORACLE_SID=orcl
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
PATH=$ORACLE_HOME/bin:$PATH
export ORACLE_BASE ORACLE_HOME ORA_NLS33 ORACLE_SID LD_LIBRARY_PATH PATH
----EOF---------
chmod 755 /etc/profile.d/oraclenv.sh
This file will run when a user logs in.
8. Install oracle DB
This took me quite a few attempts.
The first Install I did I received the error jre was not found. This issue seemed to be relating to the fact I was not installing on a Pentium 4. Oracle was looking for the jre in oracle.swd.jre/bin/i686 (and .../lib/i686) when some of the files were placed in i386 and java was looking in i386. This created a real mess. I had encountered a similar problem on a previous install on a different platform. I found articles of people that tried to just link the directories with symbolic links but this never worked. I tried my own version but also failed.
The solution that worked for me was to de-install, remove all the oracle directories created by the install (this part I had always done) AND also delete the file /etc/oraInstl.loc. This makes the Installer truly believe this is the first time Oracle has been installed on this box. My jre problem disappeared after that. (I don't know why it just didn't work in the first place...)
The next error I received was an ORA-03113 when creating the database (in the dbca). (It was actually at this point that I found the document from redhat as mentioned in my set 6 above) I also noticed that when running the install of the database, the default was for Oracle's SGA to use 70% of the available memory on my machine (I have 512M so that's 360M). Oracle instructed me to set shmmax to around 240M. This may be why the database creation failed as I thought the shmmax parameter needed to be larger that SGA. Anyway, I reduce the SGA to 50% and it worked.
This error may also have been caused by the kernel parameters not being set properly after a reboot so if you implementing stop 6 above. You may never get this problem, hopefully.
8. Install the universal Installer 2.2.0.18.0 (a prerequisite for installing the patchset 2)
You will need this to install the patchset 2. You can get it from metalink by searching for the bug number in the patch area. Search for bug/patch number 2878462 in patches. (37Meg for linux intel)
(Did you know that when oracle refer to a bug number, you should treat this as a patch number? General the bugs are not available for public viewing but oracle create a patch of the same number as a placeholder. So don't search for the bug in the site search or by doc id, go straight to the "patches" area and enter the bug number as a patch number, you'll have more success. - I only found that out today after struggling with metalink for the last 4 years)
9. Install the patchset 2
I downloaded patchset 2 (which will bring my DB version to 9.2.0.3.0) (220Meg). There is a special symbolic link command you'll need so make sure you remember to do this.
i.e.
$ cd $ORACLE_BASE/oui/bin/link
$ ln -s libclntsh.so.9.0 libclntsh.so
10. Migrate your database
I could not get this to work. The docs says I need at least 150M shared_pool_size and 150M Java_pool_size before running the startup migrate. As I only have 512Meg RAM (and shmmax set to 230M) I did hold much hope that this would work. I started my DB without the migrate option just to see if it would actually open with 300M in my pools. It did, so I shut it down and restarted with the migrate option. After 5 minutes of heavy processing (I still have an empty database) my server appeared to hang. I decided to restart the machine and just re-create my DB with the new patchset already applied. I delete my $ORACLE_BASE/oradata/<sid> directory and remove the entry from /etc/oratab and re-created my DB. This worked fine :)
I hope this document helps you for your install. Please drop me line if it does help and I'll endevour to write more documents like this one.
Please drop me a quick line at [email protected] even just to say "thanks".
I will include a few keywords here to help the searches find this document. (mainly the keywords I searched on and failed to find a doc like this one)
ORA-03113 ORA-3113 03113 3113 jre was not found jre not found i686 i386 i586 9iDB R2 9.2.0.1.0 9.2.0.3.0 Redhat Advanced Server 2.1 AS Enterprise Linux (AS) RH install error installation errors oui dbca problem issue
Good luck,
Tim Daniell.The trick that worked for me was on a 2nd attempt. I installed once, let it fail with "jre was not found", de-install through the installer, delete all directories and files under $ORACLE_BASE (including $ORACLE_HOME), and also delete /etc/oraInst.loc.
I don't know why it fixes itself with this. Oracle say this is an unresolved bug 2726268 that lies in the installer. This is still unresolved by Oracle (as at 02-June-03) therefore it is not a published bug/patch. If this doesn't work, I suggest you open an iTAR and see if Oracle has any more suggestions for you.
Cheers,
Tim. -
Problem with using database link from oracle 7 to oracle 9i
Hi To Every One
I have two oracle database oracle 7.3.4.0.1 and oracle 9i 9.2.0.1.0.
and the tns alias to connect to oracle 9i database is oracle9i and tns
alias to oracle 7 database is oracle7.I have no problem in connect to
these database using these tns aliases from either database.The tns
alias for oracle 7 is available in tnsnames.ora file of oracle9i and
tns alias for oracle 9i is available in tnsnames.ora file of oracle 7.
So there is no connection problem from each other.Connection is
working fine for each other but the problem with database links is
like this
Problem:
when i create database link from oracle9i user or public database link
from oracle9i for oracle7 user like this
SQL ORACLE9I >CREATE DATABASE LINK ORACLE7 CONNECT TO <ORACLE7USER>
IDENTIFIED BY <PASSWORD> USING 'ORACLE7';
OR
SQL ORACLE9I >CREATE PUBLIC DATABASE LINK ORACLE7 CONNECT TO <ORACLE7USER>
IDENTIFIED BY <PASSWORD> USING 'ORACLE7';
The links get created sucessfully but when i write command like
SQL ORACLE9I> DESC <ORACLE7USER_NAME>.<ORACLE7USER_TABLENAME>@ORACLE7
I RECEIVE A ORACLE ERROR LIKE
ORA-12663 SERVICE REQUIRED BY CLIENT IS NOT AVAILABLE ON THE SERVER.
OR IF MY COMMAND IS LIKE
SQL ORACLE9I> SELECT <FEILD_NAME> FROM
<ORACLE7USER_NAME>.<ORACLE7USER_TABLENAME>@ORACLE7;
I RECEIVE AN ORACLE ERROR LIKE
ORA-01002 FETCH OUT OF SEQUENCE.
ORA-02063: preceding line from ORACLE7
BUT IF I CREATE A LINK FROM ORACLE7 USER FOR ORACLE9I USER
IT WORKS FINE.
PLZ HELP ME WHAT IS THE PROBLEM THAT THE LINK FOR ORACLE 7 IS NOT WORKING WHEN
IT IS BEING CREATED FROM ORACLE9I.
Thank u.Oracle 9.2.0 does not support connectivity to Oracle 7. The newest version that will support this is 9.0.1.
