Sizing of SGA

Hi All,
OS:Windows 32 bit
RAM= 2GB
DB: Oracle 10.2.0.3
I am in a fix, my UAT server is used to run reports and it was running fine earlier but now due to a big java file , the report is not generated.
In my DB automatic SGA tuning is not enable and the SGA parameters are specified as below:
sga_max_size=1400M
Java_pool_size=32M
large_pool_size=104M
pga_aggregate_target=512M
Kindly tell me how to go about this as the RAM size of the UAT server is limited to 2GB and whether i should enable auto SGA tuning for the same, will this move help the cause?

Hi,
I tried increasing the size of java pool but i got the following error:
alter system set java_pool_size=104M scope=spfile;ERROR at line 1:
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-04033: Insufficient memory to grow pool
So can you please tell me how to go about this?
Will enabling SGA_TARGET will help the cause or can I reduce some other parameter so that it can compensate for the increase in Java pool?

  • Sizing the SGA

    Hi,
    I would like to know how to size the initial SGA size while creating the database.
    What are the things that we have to consider for sizing the SGA?
    If we have to consider if it is OLTP/DSS system, how many concurrent transactions, how many users and all, then provide me a detailed info, like if there are 100 users assign this much space, and so on.
    Thank you in advance.
    Rajesh

    See Rajesh, Tuning is not a rocket science, It can not be learned at the rate of knotes. coming back to your question, you assume your database is going to be used for OLTP, well, even that case, there are number of things still matters.
    these are...
    1. what would be the size of your database ?
    2. No of cuncurrent users conneted to oracle database?
    3. What are the physcial resources you have (cpu's, memory etc) ?
    4. Amount of sorting peromed by each session.
    5 Many more ....
    But if you really like to make an educative guess, then you can start with optimal values and increase the size according to demand. Yinguan is already suggested you to go through with tuning guide, which is the basic need for that person like to jump into tuning ocean.

  • Stream Pool Sizing and SGA AMM

    Hi DBAs,
    Just a very general question. I have enabled the SGA AMM. So the Stream Pool Size is not defined. Sometime I am getting the warning for messages are spilling over. Should I increase the SGA or Disable the Automatic Memory Managent and define the Stream Pool Size explicitly. I am using Oracle 10.2.0.4 (single instance). I have heard from some experts that SGA AMM feature doesn't scale well some time but not sure how it manage the streams pool. If SGA AMM is not enabled then SGA only allocate 10% for Stream Pool. Total System RAM is 16GB and SGA Max and Target is 8 GB.
    Should I increase the SGA AMM enabled or explicitly define the Stream Pool Size? Any suggestion please ..
    Regards
    -Samar-

    When you set SGA_TARGET, normally the value of STREAMS_POOL_SIZE is 0 and AMM allocate memory as needed by the system.
    Nevertheless, if you set it, then it means you request the minimum value for streams_pool_size not to shrink below this value.
    You did not precise if the spilling occurred on Source or on Target.
    -On source, it means that the messages are not propagated fast enough (usually this is paired with flow control in effect) and the excess messages are spilled to disk queue table.
    -On Target, it means the apply process is not fast enough, and messages received in the buffered queue table are spilled onto the disk queue table (your aq$_<queue_name>_P)                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       

  • Initial sizing of sga memory components.

    Hi to all,
    I want to know that how many granules be allocated to each sga components initially when we use automatic memory menagement. Let's say SGA _target is 1g. version 10.2.0
    thnxs in advance.

    The SGA comprises a number of memory components, which are pools of memory used to satisfy a particular class of memory allocation requests. Examples of memory components include the shared pool (used to allocate memory for SQL and PL/SQL execution), the java pool (used for java objects and other java execution memory), and the buffer cache (used for caching disk blocks). All SGA components allocate and deallocate space in units of granules. Oracle Database tracks SGA memory use in internal numbers of granules for each SGA component.
    The memory for dynamic components in the SGA is allocated in the unit of granules. Granule size is determined by total SGA size. Generally speaking, on most platforms, if the total SGA size is equal to or less than 1 GB, then granule size is 4 MB. For SGAs larger than 1 GB, granule size is 16 MB. Some platform dependencies may arise. For example, on 32-bit Windows NT, the granule size is 8 MB for SGAs larger than 1 GB. Consult your operating system specific documentation for more details.
    You can query the V$SGAINFO view to see the granule size that is being used by an instance. The same granule size is used for all components in the SGA.
    If you specify a size for a component that is not a multiple of granule size, Oracle Database rounds the specified size up to the nearest multiple. For example, if the granule size is 4 MB and you specify DB_CACHE_SIZE as 10 MB, the database actually allocates 12 MB.

  • Problem in sizing sga

    Dear All,
    We are using Oracle 10g R2 on windows 2003.Our sga_max_size=2000m and sga_target=800m.We have enabled ASM.
    I got an alert message in enterprize manger which says virtual memory paging is happening and its impact is 100%.
    Now,Is this problem related to SGA?Do i have to resize my sga_max_size ?
    We have 4gb RAM 460 gb hard disk what would be the ideal size for sga?
    Regards,
    Kris

    For guidelines over SGA & memory, refer discussion here...
    Re: windows 32bit sga and pga limits
    But actual sizing of SGA depends on your application needs. If it needs more SGA, it does. You might need to add more RAM to your server to cope up with existing workload for a given number of users.

  • SGA Cnfiguration?

    Anyone,
    I am just curious if there are rules of thumb to the ratio of DB Buffers to Shared Pool for best DB performance.
    I use DBArtisan which gives me a graphical representation of the SGA for ea db when I connect and I have one of my DB showing a pie chart that is almost all RED (i assume to be bad) vs 50 percent on another that is supposed to be same DB setup between them (one is DEV and one is TEST for same application) The red colors and purple colors are for my DB Buffers and my Shared Pool respectivley.
    Here are my stats:
    DEV
    DB Buffers (MB) 132
    DB Caches (MB) 0
    Fixed SIze (MB) 1
    Log Buffers (MB) 2
    Shared Pool (MB) 173
    Large Pool (MB) 4
    Java Pool (MB) 8
    TEST
    DB Buffers (MB) 688
    DB Caches (MB) 0
    Fixed SIze (MB) 1
    Log Buffers (MB) 2
    Shared Pool (MB) 120
    Large Pool (MB) 4
    Java Pool (MB) 4
    I am not the DBA and my DBA tells me auto config is on so the DB is supposed to be sizing the SGA itself. Do these ratios look correct?
    Thanks in advance for any input I can get.
    Miller

    There's no magic number for db buffer and shared pool ratio. It's highly depends on what is runing on Oracle.
    I take the auto config your DBA mentioned is new Oracle 10g feature ASMM
    Here's a link you will find useful information from it

  • 10g RAC SGA

    Are there any guidelines for 10g RAC SGA sizing?

    >
    if you are asking for new RAC setup, if 10g use ASSM which will automate the sizing for SGA.
    if any issues, you can use memory advisors to get the recommendations.
    >
    Little correction: The acronym here is ASMM (Automatic Shared Memory Management), activated by setting SGA_TARGET > 0
    ASSM (Automatic Segment Space Management) is also a good thing but has nothing to do with the sizing of the SGA.
    Apart from that, I agree that ASMM is the way to go with a 10g RAC, when it comes to SGA sizing.
    btw, if u use 2 many of these acronyms, u r hrdr 2 undrstnd, specially 4 nuBs, c? :-)

  • Uniform SGA sizes or not?

    Our shop is currently running Oracle Applications 11.5.10.2 on a single node database(10.2.0.2) on Sun Solaris10. We are planning to migrate to RAC(10.2.0.3) and have started work on our development servers. We are planning our production architecture and have a question related to SGA sizing between nodes.
    We our trying to get a better understanding of what our SGA sizes on each of our nodes should be if we have one large capacity node and several smaller capacity nodes. By capacity I mean the size of memory and number of CPUs. The biggest concern is the size of memory. On our large box we will have 48G and on each subsequent node we will have 32G. The SGA on the big node is currently about 12G and the PGA 8G. Combined with other memory requirements we can consume 28-30G on our server. My questions are: What is Oracle's recommendation for sizing the SGAs on the smaller nodes? If we size them based on our large node would we run into memory shortages on the smaller nodes? Does RAC require a uniform SGA size across all nodes? Thanks.

    Oracle does not require the same SGA on all nodes. All machines that are intended to share the same workload will typically have similar SGA sizing. However, machines that are intended to carry different workloads will typically have different SGA configurations.
    The SGA is node specific and is defined by the workload expected on that node. Realize that the SGA has a number of pools, the major ones being 'data buffer' and 'shared pool'.
    In very crude terms, the shared pool is used to handle the SQL & PL/SQL, and the buffer is used to handle the data being affected by the SQL and PL/SQL.
    If a node is designated to handle specific workload ("this is the batch machine", "this is the backup machine", "these machines are for the customer service team's web screens") the SQL thrown at the node will be potentially different fromn any other node and it should be sized for that workload. This is standard 'performance tuning'.
    Workload segregation is typically accomplished using the 'Service' capability of the database and listener.
    IOW, RAC does not eliminate the DBA's need to tune based on workload. The tuning is done at the instance level.

  • Sort_area_size & hash_area_size on 10g

    I am confused as to whether I need to have sort_area_size and hash_area size set in my 10.2.0.3 database. I know the Oracle documentation states the following:
    "Oracle does not recommend using the SORT_AREA_SIZE parameter unless the instance is configured with the shared server option. Oracle recommends that you enable automatic sizing of SQL working areas by setting PGA_AGGREGATE_TARGET instead." This is the same statement made for hash_area_size as well.
    I have SHARED_SERVERS set to 1. So do I need to have sort_area_size and hash_area_size configured? Or will pga_aggregate_target take over anyway?
    And does anyone have any suggestions on sizing pga_aggregate_target?
    Oracle Doc says 20% of SGA. And I have seen recommendations where SGA should be sized 60-80% of total memory. Seems extreme.

    It is extreme. The SGA can be anywhere from 5% - 50% of the total memory depending on the size of memory, size of the database, type of database application (OLTP, Warehouse, DSS, OLAP), and user load.
    What else is on the machine besides the database is a big factor in how much memory can be allocated.
    Metalink has documents on sizing the SGA. You can size the PGA based on the expected concurrent user session count X an average memory per user + some extra for the unusual. How much memory you need per user depends on the application code tool set and coding stype.
    It is a bit of a guessing game. I like to start small but probably adequate allocation and add more resource as the load grows based on statistics.

    Hi,
    but sir by setting /3gb paramter , kernel memory will be reduced by 1 GBYou only need 10-20% of total RAM for the kernel!
    It's 4GT! How much RAM is on this server?
    A VERY COMMON issue with Oracle 32-bit Windows is that the server has 8 gig RAM, but the SGA only uses 2 gig, leaving huge wasted RAM areas.
    See these important notes for sizing your SGA and PGA:
    http://www.dba-oracle.com/art_dbazine_ram.htm
    Also note that you do not have to use $GT, you can also use AWE instead:
    http://www.dba-oracle.com/oracle_tips_ram_waste.htm
    does it mean windows 32 bit platform is unfit for oracle?All 32-bit systems are constrained by addressable memory (2**32~=2 gig).
    To use larger RAM regions, you must employ special tricks In Windows, 4GT or AWE) to move the data buffers "above the line".
    Hope this helps . . .

  • KEEP GETTING ORA-04030: OUT OF PROCESS MEMORY During import using DataPump

    Hi,
    I know I have several issues with my datapump during imp, but I am stuck again people :(
    We took a expdp from an external client and we are trying to append the data to our existing db. When we do this, we keep
    getting this.
    Processing object type SCHEMA_EXPORT/TABLE/TABLE_DATA
    ORA-31693: Table data object "IWORKS"."TBLEDIFILE_DTL" failed to load/unload and is being
    skipped due to error:
    ORA-29913: error in executing ODCIEXTTABLEFETCH callout
    ORA-04030: out of process memory when trying to allocate 64528 bytes (sort subheap,sort key)
    and so on...for all the tables.
    I used 2 different impdp commands to see if I would get different results and they are:

    So basically I have looked online at Metalink and they are telling me (VIA me opening a SR with them), that I should look at Note 233869.1 Diagnosing and Resolving ORA-4030 errors
    So I did this, and the only thing that can apply to me that I am thinking is maybe I have sized my SGA too big??? I mean what else can cause this issue?

  • Which one should I drop - undo or rollback?

    I have both undo tablespace and rollback tablespace. Is it possible I can drop any one of them?
    Below is the free space in each. By looking at these figures, the undotbs1 tablespace can be dropped. Howver I neeed to know if there is any risk in dropping it ...and how to take precaution sagaint any risks?
    tablespacename || free space
    RBS || 40.91%
    UNDOTBS1 || 99.87%
    Thanks

  • Converting from RAC to Single Instance - Memory

    hi,
    we are moving forward with virtualizing our database environment and want to use 11g RACOne. We currently are using 3 node, 10g RAC. In coming up with specifications I am wondering what general rule there is for sizing the SGA. As an example if one of my databases has 3 500MB SGA's do I simply have a single instance with 1500MB SGA? I'm not sure what the approach would be.
    Any info appreciated. Thanks in advance...ron

    RonHeeb wrote:
    thanks for the response. i have been regularly taking current sizes of each SGA from gv$sgastat to see what's being allocated. my thinking is that this is a minimum and that i should add to it for peak loads, ensuring that it's not set below any minimum that RACOne requires.
    beyond that going to RACOne seems to be a direction for virtualized DB servers and for us 24 by 7 is not needed (although more than a few minutes outage would be an issue). in any case if needed we could go RAC on our most critical environments. I'm attracted to how patching/server maintenance can be achieved with RACOne.Okay, you either need high availability or you don't. if having a db go down "for more than a few minutes" is a problem then, don't you really need 24x7 ? And in that case, isn't the high availability offered by RAC is your only option? For me, having a mission critical database (and it looks like this qualifies) on anything "vitualized" is a disaster waiting to happen. I find it lunacy to have, say, 4 virtual failover servers (RACOne) on the same physical hardware. When that server crashes so does your entire failover scenario.
