If I have to create a database on server which has already 5 databases running , how will I set the memory (pga,sga) values . AFAIK it depends on o/s is linux and database version is 10g and 11g .
1)free avaialble memory on server .
2)kernel parameters .
what else has to be considering while initialize memory parameters .
I have issued to create pfile from spfile. When I run the create command it is done successfully but in my pfile content has only one parameter of *.SPfile='D:apporacleproduct11.2.0dbhome_1databaseSPFILEORCLE1.ORA'
I want to have a normal pfile with many parameters in the pfile that it can be changed.
I am reading in a selection of parameters. I have created a new variable which I want to set according to the value of one of the input parameters.
I am doing this straight after declaring the variable, but before the cursors and BEGIN statement It is throwing an error when I do this - but I have to do it before the cursors.the variable I am setting is: v_fptransType you can see the IF statement towards the end of the code.
the error I am getting is:Error(28,3): PLS-00103: Encountered the symbol "IF" when expecting one of the following: begin function package pragma procedure subtype type use <an identifier> <a double-quoted delimited-identifier> form current cursor The symbol "begin" was substituted for "IF" to continue.

I have a simple question about database sessions. The value of parameter "sessions" is set to 500 and the users connect to database through an application server(Jboss). There are more than 500 users connect to the database through application.
My question is, how more than 500 users can connect to the database without any issue, if we set the value of "sessions" parameter to 500?
I am planning to set QUEUESIZE parameter in listener.ora. In a non-rac database, we can set in %ORACLE_HOME%/network/admin/listener.ora
(ADDRESS = (PROTOCOL = TCP)(HOST = servername)(PORT = portnumber)(QUEUESIZE=n))
How to set the QUEUESIZE in a RAC Database with SCAN feature. listener.ora inside the grid home contains the following information
LISTENER_SCAN3=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN3)))) # line added by Agent
LISTENER_SCAN2=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN2)))) # line added by Agent
LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent
LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1)))) # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN2=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN3=ON # line added by Agent
and the endpoints_listener.ora contains the following (edited the host and ip details for maintaining confidentiality)
LISTENER_HOSTDB02=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=hostdb02vip)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=<ip of hostdb02>)(PORT=1521)(IP=FIRST)))) # line added by Agent
As per my understanding, QUEUESIZE parameter can be set inside the endpoints_listener.ora
how to make changes in a oracle 11g rac environment.
i was unable to log in to oracle database. i am doing the following steps :
- sqlplus /nolog
- connect /as sysdba
connect to an idle instance
- shutdown
ORA - 01034: oracle not available
ORA - 27101: shared memory realm does not exist
each command i give is showing the following error: ORA - 44412: XE edition memory parameter invalid or not specified.
i try to startup a database, and get that obsolete/deprecated parameter specified(ORA-32004: obsolete and/or deprecated parameter(s) specified)so i try to reset the parameter, but it seems it is already reset(not in spfile), so maybe this is in memory. SO now i try to reset with scope = memory or both, it gives this error(ORA-32029: resetting with SCOPE=MEMORY or SCOPE=BOTH is currently not supported).
what to do, because now i cannot reset with scope = memory and in spfile it is not there but still it comes in deprecated parameter.
I am on Oracle 11.2.0.3 on Linux and have implemented Oracle Text.I created Oracle Text indexes with default setting. However in an oracle white paper I read that the default setting may not be right. Here is the excerpt from the white paper by Roger Ford:URL....(Part of this white paper below....)Index Memory.
As mentioned above, cached $I entries are flushed to disk each time the indexing memory is exhausted. The default index memory at installation is a mere 12MB, which is very low. Users can specify up to 50MB at index creation time, but this is still pretty low. This would be done by a CREATE INDEX statement something like: CREATE INDEX myindex ON mytable(mycol) INDEXTYPE IS ctxsys.context PARAMETERS ('index memory 50M'); Allow index memory settings above 50MB, the CTXSYS user must first increase the value of the MAX_INDEX_MEMORY parameter, like this: begin ctx_ adm. set_ parameter('max_index_memory', '500M'); end; The setting for index memory should never be so high as to cause paging, as this will have a serious effect on indexing speed. On smaller dedicated systems, it is sometimes advantageous to temporarily decrease the amount of memory consumed by the Oracle SGA (for example by decreasing DB_CACHE_SIZE and/or SHARED_POOL_SIZE) during the index creation process.
Once the index has been created, the SGA size can be increased again to improve query performance." (End here from the white paper excerpt)My question is:
1) To apply this procedure (ctx_adm.set_parameter) required me to login as CTXSYS user. Is that right? or can it be avoided and be done from the application schema? This user CTXSYS is locked by default and I had to unlock it. Is that ok to do in production?
2) What is the value that I should use for the max_index_memory should it be 500 mb - my SGA is 2 GB in Dev/ QA and 3GB in production. Also in the index creation what is the value I should set for index memory parameter - I had left that at default but how should I change now? Should it be 50MB as shown in example above?
3) The white paper also refer to rebuilding an index at some interval like once in a month: ALTER INDEX DR$index_name$X REBUILD ONLINE; We are on Oracle 11g and the white paper was written in 2003.

I am trying to select multiple values from a parameter form based on a select statement.
I created the parameter and write the select statement under list-of-value property However what I want is to let users choose multiple values from the select statement not only one value.
I have a user requirement where they want to be able to select multiple values for a single parameter that will act as a filter for a report. The possible values for a parameter can come from almost any master data Oracle eBusiness table. I don't want to just present the user with a LOV where they search down a list selecting what they want. That wouldn't be very practical for selecting part numbers from 1000's of rows. I also want the user to easily see what values they have selected. I thought about providing a button that would navigate to a multi-row form where they could record their values and use those values in the where clause of the SQL for the report, but that is a somewhat complex solution I have never tried before. how to do this. I'm working in the latest version 4 of APEX.

SQL> show parameter sga;

------------------------------------ ----------- ------------------------------
lock_sga boolean FALSE
pre_page_sga boolean FALSE
sga_max_size big integer 3G
sga_target big integer 2G
from what I read I beleive this will initially grab 2GB of memory on startup and will grab up to to 3GB of memory total for the SGA. The "total" memory can be allocated to different peices of the SGA when needed but will never exceed 3GB. Is this correct or would these settings infringe on any available memory on a system that is already tight on memory?
Secondly, what happens if both these values are set to the same value?
Can i know the internal process of initialization of DB into memory in timesten , when a new connection is establishing? Will timesten create tables and indexes in RAM when first connection is established if the RAM policy is default?

After changing, i tried to startup database in nomount pfile but oracle through error that, unable to locate control file. Then, i remove the control files and tried to start database with nomount. Oracle through error about the control file.
This database, i had installed through DBCA. I want to know, where are all places where DBname reside?
Can i start database through pfile even if it is created through DBCA?
what is missing in this pfile that would cause enterprise manager not to appear ?
In the Oracle Database 10g: Administration Workshop II The chapter 8 excercise calls for the database to be started using the pfile init_sgalab.ora . The purpose of this I suppose is to simulate a memory error.
When I get to the part where I need to use OEM to fix the problem, OEM does not come up. The contents of init_sgalab.ora are :
--------------------------------------------
background_dump_dest='/u01/app/oracle/admin/orcl/bdump'
compatible='10.2.0.1.0'
control_files='/u01/app/oracle/oradata/orcl/control01.ctl','/u01/app/oracle/oradata/orcl/control02.ctl','/u01/app/oracle/oradata/orcl /control03.ctl'
core_dump_dest='/u01/app/oracle/admin/orcl/cdump'
db_block_size=8192

I am not sure what is missing in this file to be able to bring up OEM.
Also, I looked at the logs and this is the only error message I found that might be relevant in
