Package STATSPACK
Hello folks
I have the invalid package PERFSTAT.STATSPACK because the error Compilation errors for PACKAGE BODY PERFSTAT.STATSPACK because the errorr: PL/SQL: ORA-00980: synonym translation is no longer valid stats$x$ksppsv sv
Someone has an idea?
Tks

It sounds like you upgraded your database but did not upgrade the statspack package.
Look to see if you have any recent sp data - look in stats$snapshot
There are upgrade scripts provided in $ORACLE_HOME/rdbms/admin/spup*.sql
If you are on 10g, try looking at AWR data - it's much like statspack and is enabled by default.
I usually disable statspack collection after upgrading to 10g and just use AWR data (e.g. dba_hist_*)
for a standard AWR report run $ORACLE_HOME/rdbms/admin/awrrpt.sql
Cheers

HOW CAN I DEAL WITH IT?The error means "The synonym used is based on a table, view, or synonym that no longer exists." It is possible create a synonym for non-existing objects and objects of non-existing users. When tables are dropped, synonyms owned by other users still point to the objects.
I recoomend you to do the installation of statspack freeshly and cleanly. -
Error while creating statspack
i m practicing to create Statspack report
oracle 9.2 on windows
i created a database with the name bkp2. listener up and running.
i had never run the spcreate.sql in this db before
when i did run it i got the below error

NOTE:
SPCPKG complete. Please check spcpkg.lis for any errors.the code is running successfully till it starts creating the statspack package body. the tablespace and temp file which is given for the perfstat user have more than 200MB space.
interestingly when i create the same with another database in the system created both through manual and dbca, it runs perfectly.
i dont want the direct solution for this. i jus want to know how i can find out the cause for this. i tried to trace the session i.e. alter session set sql_trace=true;
still i didnt understand how to go about from there and when i searched the error in the trace it didnt appear there!! ... so in such cases how do i pinpoint which statement is causing the error. the line no. is not of much use as the whole code is full of comments in between !!
thank youi m using SYSDBA user only ...
code:
conn sys as sysdba
added:
i v also run spdrop.sql as SYSDBA and tried to re-run the spcreate.sql script several times in this database. still same results. i wonder why this happens jus to this db
i v also created a new tablespace which is not used by any other user objects. and a new temp tablespace and used them while running the spcreate.sql
still same results.

9I STATSPACK PACKAGE를 이용하여 생성된 성능보고서 분석 예제
==========================================
PURPOSE
이 문서는 9i 데이타베이스 운영 중 전반적인 System performance
저하를 경험할 경우 StatsPack Package를 이용하여 성능관련 문제
분석에 활용하는 방법을 예제를 통해 알아보기로 한다.
Explanation
<Bulletin:17118>에는 statspack.snap 프로시져를 수행하여 snapshot을
생성하는 데 있어 통계정보 수집 방법에 대하여 자세히 소개되어 있다.
<Bulletin:17119>에는 spreport.sql 수행을 통한 STATSPACK 성능 보고서
생성 방법과 생성되는 report의 내용을 요약적으로 볼 수 있다.
이 문서는 STATSPACK utility에 의해 생성되는 이 output(성능보고서)을
이해하고 진단하는 데 도움을 줄 만한 내용을 알아본다.
데이타베이스 performance tuning은 아주 광범위한 분야이므로,
아 자료는 몇 가지 특정 tuning point에 대해서만 촛점을 맞추어 알아본다.
1. 9i 에서 statspack 수행 시 Summary Information
STATSPACK report for
DB Name DB Id Instance Inst Num Release Cluster Host
ETSPRD7 1415901831 etsprd7a 1 9.2.0.5.0 YES tsonode1
Snap Id Snap Time Sessions Curs/Sess Comment
Begin Snap: 71 11-Jun-04 10:02:41 ####### .0
End Snap: 73 11-Jun-04 12:09:00 ####### .0
Elapsed: 126.32 (mins)
==> 이전의 OPS 항목은 Real Applications Cluster(RAC) 라고 하는 새로운
용어를 나타내기 위해 Cluster로 대체되었다.
그리고, Cursors/Session 과 Comment라고 하는 column이 추가되었다.
2. Oracle 9i Instance Workload Information
모든 statspack report는 instance efficiency를 결정하는 데 도움이 될
만한 인스턴스 metric들과 인스턴스의 workload profile을 보여주는 것으로
시작한다.
Oracle 9i에서 Std Block size는 인스턴스의 primary block size를 나타낸다.
1) Instance cache information:
Cache Sizes (end)
~~~~~~~~~~~~~~~~~
Buffer Cache: 704M Std Block Size: 8K
Shared Pool Size: 256M Log Buffer: 1,024K
2) Load profile Information:

Redo size: This is the amount of redo generated during this report.
Logical Reads: This is calculated as Consistent Gets + DB Block Gets = Logical Reads
Block changes: The number of blocks modified during the sample interval
Physical Reads: The number of requests for a block that caused a physical I/O.
Physical Writes: The number of physical writes issued.
User Calls: The number of queries generated
Parses: Total of all parses: both hard and soft
Hard Parses: Those parses requiring a completely new parse of the
SQL statement. These consume both latches and shared pool area.
Soft Parses: Not listed but derived by subtracting the hard parses
from parses. A soft parse reuses a previous hard parse
and hence consumes far fewer resources.

너무 빈번한 Parse를 줄이기 위한 권장사항
- Literal SQL보다는 BIND VARIABLE 사용 권장
- SOFT PARSE가 85%나 차지하므로 Session_cached_cursors 파라미터 설정 권장
( 가령 100 --> 200 )
이 파라미터에 지정한 갯수는 한 session 동안 open된 상태로 cache에
유지할 수 있는 cursor의 갯수이다.
<참고> CURSOR 는 한번 오픈된 다음 여러번 execution 될 수 있다.
예를 들어 V$SQL 뷰에서 한 SQL 이 몇번 execute 되었는지는
v$sqlarea.executions 로 확인 가능하다.

Problem with statspack package in oracle 9i
Hi
we are using oracle 9i(9.2.0.1.0).Installed stats pack package ,its created perfstat user(( created tablespace called perfstat and size 500m ) but tables not created. Afetr that
sql>conn perfstat/perfstat@x;
sql>select * from tab;
no rows selected
I had run the below scripts
@d:\oracle\ora92\rdbms\admin\spcusr.sql
@d:\oracle\ora92\rdbms\admin\spctab.sql
@d:\oracle\ora92\rdbms\admin\spcreate.sql
Thanks inadvance
MMNote that the spcreate.sql script will run all the other scripts necessary to create the perfstat user and its objects.
All you had to do was run the spcreate.sql script to all the steps necessary. -
Running statspack report remotely from a client?
Hi!
To get a statspack report I run @spreport.sql from an SQL*Plus session on the database server.
Having to go to the DB server for that sometimes is a chore and I would prefer to get a report from any client, or even from within SQL Developer.
Is there an easy way to achive this or is there a tool for that?
Obviously, the spreport.sql might differ from Oracle DB version to version, so I would either need to have a series of these reports scripts on the client and the select the right one or I would need to have some mechanisum (stored proc?) that gets to rdbms/admin on the server, executed the spreport.sql script there, read the output and return that from to the client.
Is there an easier way or anyone knows of a package that will do that?
Thanks,
MarcusMarcus,
I don't think that I did get your question. Sorry but do you mean to say that you want a report from the client terminal , running locally over teh client only? That's what I got from this line,
Having to go to the DB server for that sometimes is a chore and I would prefer to get a report from any client, or even from within SQL Developer. Or do you want the report to be available from the server side to the client's local machine?
If you want the report to be given to you on the client side only, I am not sure that there is any way possibly there. What's the issue in fetching the report from the server though ? If one can connect to db as a valid db and o/s user, he can fetch the data as well. But its just a thought. I don't use any of the tools much so I guess, I shall just join you and see what others have to say about it.

I've already suggested them to disable the indexes
and drop the constraints, but that didn't seem to work eighter. I though, you guys would able to offer something , which would make sence in order to kill the ongoing problem. Anyways, thanks for the inputs

Statspack: error with spcreate.sql in 11.1.0.7 on WIndows
Hello,
I'm trying to install statspack on a 11.1.0.7 64bit RDBMS on Windows 2008 R2.
I get this error during spcreate.sql as sysdba
... Creating views
. quisce_t*drms quiesce_time
ERROR at line 5
ORA-00904: "QUISCE_T" : invalid identifier
I wasn't able to find anything related on metalink....
Any hint?
I was previously able to run it on 11.2.0.1 and 11.2.0.3 RDBMS on Linux systems...
I don't know if it is a problem with this particular version of the rdbms.
Thanks in advance,

I don't suppose so and that the package was already invalid before... but not sure...
How to correct? I found similar cases where Oracle oly suggested catalog/catproc runs... but I would like to avoid if possible...

Poor performance when running DBMS_STATS package
Hello,
I thought I would throw this issue out to the general population as I am stumped.
I have two identical schemas on two different severs. Database in 9.2.0.6 and for QAS and Production reasons the servers and database settings are identical.
I am running the DBMS_STATS.GATHER_SCHEMA_STATS package on both databases. On the QAS DB it takes roughly 1.5 hours while on the Production database it takes 8.0 hours.
Looking at the statspack analysis, the biggest thing to jump out at me is that the temporary tablespace is getting 4.6 Million I/O hits (reads) while the QAS is only getting a few thousand.
So .... this sort of indicates that something is going on in the PGA which could cause Oracle to use the TEMP tablespace. However when I look in the host performance (using Grid Control) the servers memory, file I/O, and CPU while high are not over 80%.
Has anyone else seen and issue like this? Any ideas where to look?
Thanks,
ChrisTo the extent that you are gathering histograms on the data, Oracle potentially has to do a reasonable amount of sorting. If one machine has substantially more physical RAM, that presumably implies that it has more RAM available for the PGA, which would allow more sorts to happen in memory rather than on disk.
Depending on how you create a "refresh copy of production" and what parameters you are passing in to DBMS_STATS, it is also possible that the quality assurance database is gathering substantially more histograms than the production database (i.e. you refresh lower environments via export and import rather than doing an RMAN clone and tell Oracle to gather histograms on any columns that currently have histograms).

Please help if anyone has any idea on this forum, how do i start the logs applying the to logical standby.
ThanksHi reega,
Thanks for your reply, our logical stdby has '+RT06_DATA/RT06'
and primary has '+OT06_DATA/OT06TSG001'
so we are using db_file_name_convert init parameter but it doesn't work.
Is there any thing particular steps hiding to use this parameter? as i tried this parameter for rman cloning it din't work, as a workaround i used rman set new name command for clonning.
Let me know if you have any questions.
Thanks in advance.

How to install acrobat professional 7 on windows 8
