  Dear friend,

  Why do you think you have problems with shared pool? In the ASH report you are provided, there was just 2.5 medium active sessions and 170 requests during this period, he is very low with swimming pool shared, problems
  you have some queries that use literals, it will be better to replace literals with bind variable if possible, or you can set the init cursor_sharing parameter to force or similar, this is the dynamic parameter.
  But it is not so dramatic problem in your case!

  From ASHES of your report, we can see that top wait events is "CPU + wait for CPU", "RMAN backup & recovery i/o" and "log file sync" and 65% of your database of waiting time. And even in the background waiting events.
  If I understand well report, you have two members in your redo log groups, you have problems with log IO writer speed, check the distribution of files on the disc, newspaper editor is slow causing it to wait for the other sessions. High
  processor can be related to rman compression. Best service can we sea GATHER_STATS_JOB consumes 16% of activity 33% consumes rman and only 21% your applications and also there is something running
  SQL * more under the sys (?) account. There is from the top of the sql page, this is the sql in your application, if I understand correctly, 'scattered db reading file' event indicates that full scans have a place, is it normal that your application? If Yes, then try using
  running in parallel, as we can see in the section "Sessions running PQs Top" your report there is no running in parallel, but as I understand it there are 8 processors, try to use parallel executions or avoid full scans. But consider that
  When you do full scans in parallel PGA memory not used CMS, then decrees setting pga_aggregate_target SGA and increase respectively.

  Is there another application or a program running on the server except oracle?
  Is the performance degradation was strong, I mean yesterday, everything was ok, but today all the evil, or it was good?

  Check the reasons for the slow newspaper writer, it can greatly affect performance.
  Also of 90% of the performance problems generally because of the poor sql, poor execution plans.
  Also if you use automatic memory management, tap Settings, but you must know that in this case the settings will identify the minimum values, this is why define them to lower values in oracle can manage
  entirely.
  Don't increase your SGA at this stage, get the awr report, use @$ORACLE_HOME/rdbms/admin/awrrpt.sql, check your cover shot.

  BUT first, you must change your backup strategy, look at my first post, after that check performance again, before you do that it will be very difficult to help you.

  Good luck

• Performance monitor reports OS check failure

  A few days ago Norton IS (to date) has reported that it had prevented a Trojan attack. I ran Norton Power Eraser and removed the Trojan horse. Also ran Malware Bytes it didn't report any problems.

  However, since then, I noticed some strange things.

  1. the performance reports monitor produces virus - anti but Norton is short. Have seen other posts of this topic and that it does not cause a problem, I'm happy wait for the fix fully tested in next SP.

  2. performance monitor reports also under alltests OS checks failed, version OS check Failed.

  3. I tried to run Fix IT for a similar sounding problem and get the message in case of problem cannot continue because an error has occurred. Download the utility for troubleshooting and enforcement it detects no problem.

  4. Furthermore, in performance under traceptHeader monitor, I get this message "the WMI class data service is not available.

  5. I tried to run restore but that crashes after it restarts.

  6 folder Admin Tools proved to be empty, but which were fixed by downloading a new set of tools.

  I presume that the Trojan horse did some damage before he was eliminated.

  It is better to repair Windows running or is there something else I need to do?

  Win 7 64 bit SP1 entirely up-to-date, Norton IS perfectly up-to-date.

  Thank you

• [ORACLE 10.2.0.5] performance problem with high enq: TX - line lock contention waiting

  Hello

  I have a performance problem involving high line response to locking conflicts that I can't wait.

  The application updates the specific table about 1200 times for my AWR report representing 2 hours.

  This update represents 98% of the db_time and wait to enq: TX - line lock conflict is:

  -83 796 waiting

  -245 441 seconds

  The application updates a row both an unprecedented SELECT UPDATES. This is the query:

  Update my_table set creationtime =: 1, modificationdate =: version 2, =: creationuserid 3, =: fortesting 4, =: 5, modificationuserid =: participation_uuid 6, =: actimenucontact 7, =: allegroid 8, =: campaign_uuid 9, =: desjardinsemployeetype 10, =: effectiveparticipationtype 11, =: family_uuid 12, =: fetchpasseport 13, =: 14, healthratingfilldate =: hoursofsleeptimecommitment 15, =: igaid 16, =: initialsubscriptiontype 17, =: minutesofsleeptimecommitment 18, =: goal 19, =: partner_uuid 20, =: 21, promotionalemails =: 22, readrules =: sccsubscriptionprovenance 23, =: = subscriptionprovenance 24,: 25, supportemails =: where the 26 uuid = : 27 and = version: 28

• Performance problems on Oracle 11 G with Windows 2008 64 bit.

  Hello world
  
  I noticed that our database is going bad and low every week. My server has 16 GB of RAM and 10 GB are dedicated to the database Oracle, it is a 11.2.0.1 with Windows 2008 R2 SP1 64 bit. I would like to know according to the values of the movement following you guys recommend to adjust in the init.ora:
  
  ORCL.__db_cache_size = 5402263552
  ORCL.__java_pool_size = 33554432
  ORCL.__large_pool_size = 33554432
  ORCL.__pga_aggregate_target = 3657433088
  ORCL.__sga_target = 6878658560
  ORCL.__shared_io_pool_size = 0
  ORCL.__shared_pool_size = 1308622848
  ORCL.__streams_pool_size = 33554432
  
  * .memory_target = 10511974400
  * .open_cursors = 5000
  
  * .optimizer_mode = "RULE".
  * runoff = 300
  
  According to the target memory on how values can be increased the process, pga_agregate_target, etc.
  
  We also have problems with the bug Bug 9593134 "connection to Oracle 11 g are slow and can take anywhere from 10 seconds to 2 minutes." there is a difficulty on linux by removing dns names on this subject, but someone has experience on windows platforms?
  
  Thanks to all and sorry for my English.
  
  Kind regards.
  
  Arturo.

  Concerning the long connection times, have you tried to use the network (such as Wireshark) packet capture software to determine that the client computer when a connection attempt is initiated?

  The Oracle database time can help the model statistics and wait events extensive system you diagnose performance problems related to poor (you should not only look at the statistics, but rather capture the current values, wait a while, statistics capture again and compare the evolution of the values of the statistics). A statspack report may also help - but a trace 10046 to level 8 or 12 is more appropriate if you are able to identify a few sessions that have performance problems.

  I claim not just blindly changing the settings, even if I'm curious about:
  * Why the session level setting OPEN_CURSORS is set to 5000 - you expect a single session to hold cursors open 5,000?
  * Why do you use the obsolete RULE based optimizer?
  * Why the MEMORY_TARGET parameter is used when the target SGA_TARGET and PGA_AGGREGATE are specified?

• EBS 11i performance problem

  Hi hussein, helios, & all,
  
  
  Happy New Year to you :)
  I hope we have a better year 2011 year of the rabbit.
  I hope that we have even better in 2011.
  
  I just want to learn something from each of you through the year 2010.
  
  Can you share how tackle you performance problems in EBS?
  I know that there is joint action, that you have done to improve performance.
  It should be after all statistical analyses of performance as Statspack, SAR,
  and other output of the performance monitoring report.
  
  What actions / solutions did you resolve performance issues in EBS?
  
  Is it upgraded the server itself for a more powerful?
  
  For example, our users are complaining about the Oracle Apps very slow race at any time of the day. This produces 20% of the day(performance problem) and 80%, as the Oracle applications is running fine (no complaints of users).
  The appearance of performance problem is not fixed in time, sometimes in the morning and in the afternoon sometimes. Sometimes, even when there are a few users logged in and sometimes it is no problem of performance, even if many users are connected. If you run a statspack you see programs to eat a lot of resources, but they are oracle programs if you can not touch or tune right? So to keep users calm, they agreed to get rebooted server. Temporarily, this solves the performance problem. So we just keep it this way. My suspect is that there are many programs of concurrent background (on request) who is running who is right for which users get slow even if only a few is connected to it. I want to know what are simultaneous programs running at the time where the performance issue of gets users.
  Is there a sqlplus program to list all concurrent programs running?
  
  
  Thank you very much

  What actions / solutions did you resolve performance issues in EBS?

  Depends on what kind of performance issues you have.

  Is it upgraded the server itself for a more powerful?

  Not necessarily.

  For example, our users are complaining about the Oracle Apps very slow race at any time of the day. This produces 20% of the day(performance problem) and 80%, as the Oracle applications is running fine (no complaints of users).

  What part of the application? What activities do you have when there are performance issues?

  The appearance of performance problem is not fixed in time, sometimes in the morning and in the afternoon sometimes. Sometimes, even when there are a few users logged in and sometimes it is no problem of performance, even if many users are connected. If you run a statspack you see programs to eat a lot of resources, but they are oracle programs if you can not touch or tune right? So to keep users calm, they agreed to get rebooted server. Temporarily, this solves the performance problem. So we just keep it this way.

  Is there a program of sqlplus to the list of current jobs running?
