Parallel_max_server  and max process

Hi,
is there any initial parameter like : max process ?
is there any relation between parallel_max_server  and max process ?
I can not understand the last post of the followin thread :
Getting error in TNS connection from Oracle hosted on LINUX machine
I have the same TNS_12564 error.
Thanks.

Mines are :
SQL> show parameter process
NAME                                 TYPE        VALUE
processes                            integer     150
parallel_max_servers           
integer
40
Do I have to change them ?
I see nothing inherently wrong with them. Out of 150 processes, a maximum of 40 can be allocated to Parallel Slaves. It all depends how well you're managing/using parallel option on your workload.

  • Need to increase max process in the init file. Please check and correct me

    Friends,
    We have Oracle9iR2 database in the RHEL AS 3.0 box.
    Sometimes we are getting ORA-00020, means the max process is reached.
    We have planned to increase the max process from 150 to 250 in the init.ora file.
    i think the init.ora will be in /u01/app/oracle/admin/ourdb/pfile/
    correct me if i am wrong......
    Step1: vi init.ora file and change the process from
    processes=150
    to
    processes=250
    while the database is running.
    Step2:shutdown the database and start the database.
    is there only 2 steps or i have to shutdown the db at the beginning itself?
    Or i have to take any precautions. Our server is HP ML-370 with dual processor.
    Thanks

    1. Why can't i just edit the init.ora file to change the processes=250 while the db is running?
    you can edit the init.ora file.
    If i edit the init.ora file by shutting down the db will there any problem
    not problem
    init.ora file is text file you can edit easly
    spfilesid.ora file is binary file you can not edit directly ... if you want to edit spfile file first change in pfile then create spfile from pfile...
    hope this helps

    Ok it looks to me that there are more than 20000 rows in your backend system that have to be fetched.
    You can change this limit in the Central Management Console . Login as administrator and go to Servers . Double-click on the Crystal Processign server and change the value in the field Database Records Read When Previewing or Refreshing (0 for unlimited) according to your needs. AFter the change you have to restart the Crystal processing server.

  • OWB mappings to skip rows that are in error and continue processing

    OWB mappings to skip rows that are in error and continue processing.
    1) Enter a record into an error log
    2) Skip rows that are in error
    3) and continue processing
    Type of information could be needed in the error log:
    SY_LOG_ERROR_KEY
    ERROR_TIMESTAMP
    MAP_NAME
    SOURCE_RECORD
    ERROR_CODE
    ERROR_MESSAGE
    ERROR_NOTES
    Example:
    If the source table has five records, in that 3 records has some error.
    When I run the OWB mapping to load the source data to target table, OWB should skip the 3 record and load all the remaining record. This is our requirement.
    Another think I want to store the error record details in a error log table.
    Can u plz tell me whether it is possible in OWB. If not means please give some suggestion to do this.

    Hi,
    thanks for ur help, As is OWB version is 10.2.0 so for set based it is not working. with your idea i create a POST PROCESSING MAPPING. it is now working fine.
    Step 1:
    Create a table MAP_ERROR_LOG.
    Script:
    CREATE TABLE MAP_ERROR_LOG
    ERROR_SEQ NUMBER,
    MAPPING_NAME VARCHAR2(32 BYTE),
    TARGET_TABLE VARCHAR2(35 BYTE),
    TARGET_COLUMN VARCHAR2(35 BYTE),
    TARGET_VALUE VARCHAR2(100 BYTE),
    PRIMARY_TABLE VARCHAR2(100 BYTE),
    ERROR_ROWKEY NUMBER,
    ERROR_CODE VARCHAR2(12 BYTE),
    ERROR_MESSAGE VARCHAR2(2000 BYTE),
    ERROR_TIMESTAMP DATE
    TABLESPACE ODS_D1_AA
    PCTUSED 0
    PCTFREE 10
    INITRANS 1
    MAXTRANS 255
    STORAGE (
    INITIAL 80K
    MINEXTENTS 1
    MAXEXTENTS 2147483645
    PCTINCREASE 0
    BUFFER_POOL DEFAULT
    LOGGING
    NOCOMPRESS
    NOCACHE
    NOPARALLEL
    MONITORING;
    Step 2:
    Create a sequence MAP_ERROR_LOG_SEQ
    CREATE SEQUENCE MAP_ERROR_LOG_SEQ START WITH 1 INCREMENT BY 1
    Step 3:
    Create a procedure PROC_MAP_ERROR_LOG through OWB.
    In this i have used 3 cursor, first cursor is used to check the count of error messages for the corresponding table(WB_RT_ERROR_SOURCES).
    The second cursor is used to get the oracle error and the primary key values.
    The third cursor is used for get the ORACLE DBA errors such as "UNABLE TO EXTEND THE TABLESPACE" for this type errors.

  • How to create parent and chile process in java

    i'm beginning in java, and i want to ask something, please help me...
    1. i want to ask how to create parent and child process in java???
    example :
    if have one window and explore menu, when i click the explore menu.
    new window come out.
    how if i close the parent window the child window will close too...
    2. what is the method from runtime class to get available memory and Active Threads count

    ONE way to do what you wanted is this.
    class Parent{
    Child c = new Child
    allChildren.add(c);
    //if close
    iterate through list
    (Child)allChildren.get(index).close();
    ArrayList allChildren;
    class Child{
    public void close(){ }
    i dont know if you can get the thread count. but you can
    get the current thread by using System.
    Memory: Runtime.freeMemory() .maxMemory() .totalMemory()
    http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html
    Careful though you have to do a calculation to get the
    actual memory because those 3 methods refer to freeMemory
    of the CURRENT heap not the total memory.
    i think its: total - (max - free)

  • Changing Default  "Keep Alive" & " Max Processing Time" values in SMICM

    Dear Experts
    As you aware the default values in SMICM --> Go to --> Services The default values "Keep Alive" & " Max Processing Time" of services like HTTP & HTTPS is 30 sec & 60 seconds respectively.
    Every times when we restart application server - we are increasing the time values manually. once we restart they will be reset to original 30 & 60 sec respectively.
    I want to make customozed values permanently which should not be lost even after restart of application server.
    Please Help
    Regards
    PR

    If you have not set the PROCTIMEOUT parameter, TIMEOUT (or icm/keepalive_timeout) defines both the processing timeout and the keepalive timeout. Also, as of release 6.40, the keepalive timeout is limited to a maximum of 30 seconds.
    In a system where the default timeout settings of 30 seconds for the keepalive timeout and the processing timeout are not sufficient because of long-running applications, we recommend that you set the TIMEOUT and PROCTIMEOUT parameters for the relevant services so that you can configure them independently of each other. In addition, we recommend that you do not set the TIMEOUT value higher than necessary, for example, to the usual default value of 30 seconds.
    We recommend, for example, the following settings:
    icm/server_port_0 = PROT=HTTP,PORT=1080,TIMEOUT=30,PROCTIMEOUT=600
    to allow a maximum processing time of 10 minutes.

  • Error: Max processing time or Max records limit reached

    Hi All,
    While I run the report in Infoview, I get the below error:
    Unable to retrieve object:
    Max processing time or Max records limit reached
    Kindly suggest me.
    Thanks,
    Meena

    There is a default limit on the number of records returned and on the time out of an 'idle' connection..These could be set in the CMC , however first try to check the query for that report and see if it is applying your record selection criteria at the database level  ( use the Show Sql option and see if all your selection criteria have been turned into WHERE clauses)
    - this will drastically reduces both the number of records returned to the Crystal and the time it takes for...
    You can find setting here:
    CMC>servers>page server>properties
    Its always not recommended to set it to unlimited as page server is not a robust server, you need to schedule such reports that uses job server which is more robust.

  • Using actions and batch processing to maximize compatibility on old psd files

    My apologies if this has been answered -- in my search I saw that it was asked multiple times, but not answered.
    My goal is to be able to import 5 years of PSD files into Lightroom that were originally saved with maximize compatibility turned off. These files are in shoot folders within year folders.
    I have been trying to do this with an action and batch processing through Bridge (Tools>PS>Batch). After switching preferences to MC=always, I have tried an action with a Save command, but that doesn't switch the file to max compat on. Save As does, but it also fixes the destination of the save in the action to a specific folder. I want to be able to overwrite the existing PSD file, leaving it where it is.
    Has anyone successfully tackled this issue? I know I can handle it folder by folder, with an action for each folder, but that just wouldn't be cool.
    Thank you

    L Show - Yes, I found a way and did just that.
    Everything as you wrote, using the save-as option. Yes, it will put the folder name into the action BUT it will override it when you run your batch from bridge IF you check in the box "override action save-as command" (and destination: save and close).
    Works like a charm (although slow - not utilizing the multiple cores :( )

  • Max processes

    hi..
    we are using oracle 10gR2
    we have created database with default parameters...
    so earlier porcesses and sessions value were 150 and 170 respectively..
    after some time we got an eorror that max no. of processes exceeded...
    so i have increase both parametes to 300 and 320 respectively...
    after creating some more schema i again got this error so i again increase both parametes to 400 and 420 respectively..
    after some time some new schema created and because of the same error i have finaly made it 500 and 520.
    i have never analyze why this error frequently comming.. because i only know that whenever max processes or max sessions exceeds u have to increase the current value...
    is there there any problem on database if i m keep on increasing this value..
    is there any way to get rid of this problem...

    Hello,
    You can set higher value for processes, sessions and transactions in your system depending upon how much RAM you got on your machine and how much you can afford to give Oracle processes. So what will be happen if you keep increasing these parameter, eventually you will run out memory for very higher number of connection and either application will stall and database. So I recommend make sure your time out idle connections (over 30 Mins) to release memory. Also analyze your application which making connection and not releasing them but keep in mind you have to plan for future as well, so analyze connection growth over past month or so and alllocate accordingly.
    Regards

  • Max processes issue (but not a processes parameter issue)

    I am having ora-0020 max processes issue, but my max processes is set to 550, and I have a highwater mark of 132 processes
    select * from v$resource_limit
    where resource_name = 'processes';
    RESOURCE_NAME CURRENT_UTILIZATION MAX_UTILIZATION INITIAL_ALLOCATION LIMIT_VALUE
    processes 52 132 550 550
    This is a 2 node RAC cluster, and this only happens on one of the nodes. Anyone every see anything like this ?? It looks like some sort of leak with process handles or something.

    This does seem quite strange. What version are you running?
    ORA-0020 does seem to be a problem at the instance level, not the underlying O/S.
    $oerr ora 20
    00020, 00000, "maximum number of processes (%s) exceeded"
    // *Cause:  All process state objects are in use.
    // *Action: Increase the value of the PROCESSES initialization parameter.If the problem was at the O/S level, I'd expect an ORA-12500, "TNS:listener failed to start a dedicated server process".

  • MDS and mdworker processes gone wild

    Ever since I upgraded to Lion on my Macbook Pro I am getting intermittant periods where the MDS and MDWORKER processes completely take over the CPU and all apparent activity for minutes at a time. It's now been a week, so I'm quite sure Spotlight is done indexing the drive. What are my options?

    I'm having the same problem you are, and I'm exploring options.
    First I noticed that Backblaze (backup service) was causing the problem, but I fixed that by including the /library/backblaze folder in Spotlight's privacy area. The complete lockup that was causing is now no longer a problem.
    However, I'm noticing that most of the cycles are going to indexing my Time Machine backups, which Spotlight will not allow in the privacy area. It looks like it's indexing many of my old mailbox files from mail.app that are backed up on the Time Machine (Time Capsule) disk. I really don't see the logic to this. I've had the computer on and idling with full access to Time Machine for many days now and this is still going on, with MacBook Pro fans running at full gun and CPU not quite maxing out, but frolicking between 5% and 65% or so on a regular basis with no other apps present. Activity monitor doesn't show anything else hogging cycles -- it's all mds and mdworker.
    Something isn't right with this. I hope that the next update from Apple will fix this, or someone on the intertubes will come up with a quick solution.
    All the above is on a MacBook Pro (late 2008). I do note that I have a MacBook Air (late 2010) that backs up to the same Time Machine but does NOT have Backblaze installed. (I put everything important on the MacBook Pro.) This machine does not seem to have these problems. Both computers are running Lion and have much of the same software. Backups are doing fine on both machines.
    My temporary solution is to turn OFF Time Machine on the MacBook Pro. This does seem to make things much better -- although even at 5% CPU use the fan runs somewhat higher revs than I was used to with Snow Leopard. I then run a manual Time Machine cycle just before I turn in for the night. When I'm back to using the machine again, I make sure the Time Capsule is not mounted. I'm backing up any working files continually to Backblaze still, as well as to Dropbox, so cutting the Time Machine frequency down to once or twice a day is not too bad for now. I do not want this to continue, however.
    Also, I have done the following: Repaired disk permissions, reset the SMC and PRAM, and started the computer up in safe mode fully, and then restarted in regular mode.
    If anyone has any possible fixes, I'm listening and thanks!

    The query is re-issued as a flashback query and the client process can continue to fetch from the cursor. This is described in the Net Services Administrators Guide, the section on Transparent Application Failover.

  • Has anyone used a touch screen monitor with scxi.I am having video lock ups while using LV and MAX

    I have a PCI-MIO-16XE-50 daq card (dev1) connected to a scxi-1000 chassis address 0 ID 1, with a scxi-1102,1163,1163,1162 slots 1,2,3,4 respectively.Cable is connected to daq card to 1102 card .Micro touch screen is used on com2. Have tried other serial ports 1,5. Touch screen works fine with windows until LabView and max is installed .Video lockups,Max failures occur.MAX seems to confict with touch screen.

    Max is the NI interface for all the drivers. It may be a specific driver that is causing problems, perhaps NI-VISA. I would try installing things one piece at a time. Might want to start by uninstalling everything so that you start with a clean system. First install LabVIEW with no drivers at all. See if the Micro touch screen still works. Then try installing NI-DAQ. Install each of the drivers you need one at a time. If you don't need something, leave it out.

  • Return and Exchange process in CSC

    In CSC Return and Exchange process, While Returning an Item, Refund type is Store Credit. How to change Refund type as credit card?
    Thanks in Advance.

    You can check out the products and services tab on this website - follow the instructions and it will let you if you are still under warranty and also let you know how much apple will charge to replace the battery. Also, check out MacResQ.com and compare prices. I believe I read that Apple Stores will give you a 10% discount for a trade in and there are some online places that will let you trade up also.
