session_cached_cursor
Hello
I use the suite of applications (from the oracle documentation) to check session_cached_cursors.
I need to increase session_cached_cursors? Know if it would be part of the SGA and PGA? It must be that the amount of memory in this case increases to place cursors? Work on 11 GR 2.
If it is independent of multiple sessions created for the same user?
Percent found in the cache is too high, I don't know why...
Please provide suggestions.

AND b.name = 'session cursor cache count ';

Hi Don,
> My cursors opened for the session are about 330.
So if you want to keep more than 330 cursors open, you need to increase and open_cursors session_cached_cursors. However, if you ever notice the cursor manipulation depends on your application and you should not focus on ratios, but rather on the response time which is devoted to the analysis of soft (latch, lock, etc.).
> I just activated automatic memory and configure the settings memory_max_target and memory_target. I can't ignore sga, pga components now?
How should we know? If you set big enough memory_target and Oracle does its job of automatic memory management right-, then Yes.
> cursor_sharing is set to EXACT, what I need to change that to FORCE to get the slider adjustment... sharing?
First of all, to answer the question: is your application using the cursor cache in the case of PL/SQL cursor or cursor in the session. Then, you must answer the question, if ACS applies in your case. However you should also consult the documentation to get the idea behind ACS as mentioned parameter has nothing (directly) to do with the ACS. It is no longer relevant in the case of literals, but if set you it in the context to your question session_cached_cursors you probably rather a problem of implementation of request a matter of setting of database.

Hi Experts,
I am new to Oracle. Ask for your help to fix the performance of a query of insertion problem.
I have an insert query that is go search for records of the partitioned table.
Background: the user indicates that the query was running in 30 minutes to 10 G. The database is upgraded to 12 by one of my colleague. Now the query works continuously for hours, but no result. Check the settings and SGA is 9 GB, Windows - 4 GB. DB block size is 8192, DB Multiblock read file Count is 128. Overall target of PGA is 2457M.

Firstly, thank you for posting the 10g implementation plan, which was one of the key things that we were missing.
Second, you realize that you have completely different execution plans, so you can expect different behavior on each system.
Your package of 10g has a total cost of 23 959 while your plan of 12 c has a cost of 95 373 which is almost 4 times more. All things being equal, cost is supposed to relate directly to the time spent, so I expect the 12 c plan to take much more time to run.
From what I can see the 10g plan begins with a scan of full table on DEALERS, and then a full scan on SCARF_VEHICLE_EXCLUSIONS table, and then a full scan on CBX_tlemsani_2000tje table, and then a full scan on CLAIM_FACTS table. The first three of these analyses tables have a very low cost (2 each), while the last has a huge cost of 172K. Yet once again, the first three scans produce very few lines in 10g, less than 1,000 lines each, while the last product table scan 454 K lines.
It also looks that something has gone wrong in the 10g optimizer plan - maybe a bug, which I consider that Jonathan Lewis commented. Despite the full table scan with a cost of 172 K, NESTED LOOPS it is part of the only has a cost of 23 949 or 24 K. If the math is not in terms of 10g. In other words, maybe it's not really optimal plan because 10g optimizer may have got its sums wrong and 12 c might make his right to the money. But luckily this 'imperfect' 10g plan happens to run fairly fast for one reason or another.
The plan of 12 starts with similar table scans but in a different order. The main difference is that instead of a full table on CLAIM_FACTS scan, it did an analysis of index on CLAIM_FACTS_AK9 beach at the price of 95 366. It is the only main component of the final total cost of 95 373.
Suggestions for what to do? It is difficult, because there is clearly an anomaly in the system of 10g to have produced the particular execution plan that he uses. And there is other information that you have not provided - see later.
You can try and force a scan of full table on CLAIM_FACTS by adding a suitable example suspicion "select / * + full (CF) * / cf.vehicle_chass_no...". "However, the tips are very difficult to use and does not, guarantee that you will get the desired end result. So be careful. For the essay on 12 c, it may be worth trying just to see what happens and what produces the execution plan looks like. But I would not use such a simple, unique tip in a production system for a variety of reasons. For testing only it might help to see if you can force the full table on CLAIM_FACTS scan as in 10g, and if the performance that results is the same.
The two plans are parallel ones, which means that the query is broken down into separate, independent steps and several steps that are executed at the same time, i.e. several CPUS will be used, and there will be several readings of the disc at the same time. (It is a mischaracterization of the works of parallel query how). If 10g and 12 c systems do not have the SAME hardware configuration, then you would naturally expect different time elapsed to run the same parallel queries. See the end of this answer for the additional information that you may provide.
But I would be very suspicious of the hardware configuration of the two systems. Maybe 10 g system has 16-core processors or more and 100's of discs in a matrix of big drives and maybe the 12 c system has only 4 cores of the processor and 4 disks. That would explain a lot about why the 12 c takes hours to run when the 10 g takes only 30 minutes.
Remember what I said in my last reply:
"Without any contrary information I guess the filter conditions are very low, the optimizer believes he needs of most of the data in the table and that a table scan or even a limited index scan complete is the"best"way to run this SQL. In other words, your query takes just time because your tables are big and your application has most of the data in these tables. "
When dealing with very large tables and to do a full table parallel analysis on them, the most important factor is the amount of raw hardware, you throw the ball to her. A system with twice the number of CPUS and twice the number of disks will run the same parallel query in half of the time, at least. It could be that the main reason for the 12 c system is much slower than the system of 10g, rather than on the implementation plan itself.
You may also provide us with the following information which would allow a better analysis:
- Row counts in each tables referenced in the query, and if one of them are partitioned.
- Hardware configurations for both systems - the 10g and the 12 a. Number of processors, the model number and speed, physical memory, CPU of discs.
- The discs are very important - 10g and 12 c have similar disk subsystems? You use simple old records, or you have a San, or some sort of disk array? Are the bays of identical drives in both systems? How are they connected? Fast Fibre Channel, or something else? Maybe even network storage?
- What is the size of the SGA in both systems? of values for MEMORY_TARGET and SGA_TARGET.
- The fact of the CLAIM_FACTS_AK9 index exist on the system of 10g. I guess he does, but I would like that it confirmed to be safe.

Hello
If the new server or secondary server has the same directory as the primary structure or old, so you don't have to worry about these settings.
(Edit)
You can read about the settings in the following link:

The adaptation and Pl/SQL cursor sharing
Hello
I have this database:
NLSRTL 11.2.0.1.0 Production Oracle Database 11g Enterprise Edition 11.2.0.1.0 64 bit Production PL/SQL 11.2.0.1.0 Production AMT for Solaris: 11.2.0.1.0 Production I'm testing the queries and adaptive cursor sharing. I have a table T1 that is created by selecting all object. It has additional is NOT NULL ID of the column that is PK and is filled through sequence. It has a regular index (OBJECT_TYPE, OBJECT_NAME). Statistics are collected on the T1 table and its indexes.
Total of T1 lines and are 1065951.
I have run this test in SqlPlus:
ID of the VARIABLE NUMBER;
EXECUTE: id: = 10;
SELECT COUNT (*) FROM t1 WHERE id <: id;
So I check the instruction in v$ sql and the execution plan and I can see that the plan is:
SQL_ID, 3m2qaytqgk9jt, number of children 0
-------------------------------------
Select COUNT (*) from t1 where id <: id
Hash value of plan: 212448250
---------------------------------------------------------------------------
| ID | Operation | Name | Lines | Bytes | Cost (% CPU). Time |
---------------------------------------------------------------------------
| 0 | SELECT STATEMENT | | | | 193 (100) | |
| 1. GLOBAL TRI | | 1. 6. | |
|* 2 | INDEX RANGE SCAN | PK_T1 | 99999. 585K | 193 (1) | 00:00:03 |
---------------------------------------------------------------------------
Information of predicates (identified by the operation identity card):
---------------------------------------------------
2 - access("ID"<:ID))
Second test:
ID of the VARIABLE NUMBER;
EXECUTE: id: = 1000000.
SELECT COUNT (*) FROM t1 WHERE id <: id;
Execution plan:
SQL_ID, 3m2qaytqgk9jt, number of children 1
-------------------------------------
Select COUNT (*) from t1 where id <: id
Hash value of plan: 1953966236
-------------------------------------------------------------------------------
| ID | Operation | Name | Lines | Bytes | Cost (% CPU). Time |
-------------------------------------------------------------------------------
| 0 | SELECT STATEMENT | | | | 559 (100) | |
| 1. GLOBAL TRI | | 1. 6. | |
|* 2 | FULL RESTRICTED INDEX SCAN FAST | PK_T1 | 1000K | 5859K | 559 (2) | 00:00:07 |
-------------------------------------------------------------------------------
Information of predicates (identified by the operation identity card):
---------------------------------------------------
2 - filter("ID"<:ID))
Output:
SQL > SELECT sql_id, child_number, executions, 'IS_BIND_SENSITIVE', 'IS_BIND_AWARE', 'IS_SHAREABLE' OF V$ SQL WHERE SQL_ID = "3m2qaytqgk9jt";
THE EXECUTIONS OF CHILD_NUMBER SQL_ID I I I
------------- ------------ ---------- - - -
3m2qaytqgk9jt 0 2 O N N
1 3 3m2qaytqgk9jt Y Y Y
As we can see it Adaptive cursor sharing has been used and in both cases the appropriate execution plan has been used.
When I run test with PL/SQL block, however, I don't see the use of extended cursor sharing. Could you please help understand why?
The test is (I used deliberately < = in order to create the new parent cursor):
DECLARE
PID NUMBER;
CNT PLS_INTEGER;
BEGIN
BECAUSE me in 1... 10 LOOP
IF i IN (2, 4, 6, 10) THEN
PID: = round (dbms_random.value (1, 5000));
ON THE OTHER
PID: = round ((100000, 1600000) dbms_random.value);
END IF;
dbms_output.put_line ('ID: ' | pid);
COUNT (*) of SELECT INTO cnt FROM t1 WHERE id < = pid;
END LOOP;
END;
/
Output of this is:
ID: 396582
ID: 2584
ID: 560405
ID: 3275
ID: 827442
ID: 4515
ID: 167771
ID: 652411
ID: 512147
ID: 230
As we can see some ID values are good candidates for INDEX BEACH, others are for the INDEX FAST FULL SCAN. However, I am only a child cursor for my parents:
SQL > SELECT sql_id, child_number, executions, 'IS_BIND_SENSITIVE', 'IS_BIND_AWARE', 'IS_SHAREABLE' OF V$ SQL WHERE SQL_ID = "6xh03mm87nmu3";
THE EXECUTIONS OF CHILD_NUMBER SQL_ID I I I
------------- ------------ ---------- - - -
0 10 6xh03mm87nmu3 Y N Y
SQL >
Please pay attention to the value for IS_BIND_AWARE, who is with my first child 0. So no other children were created. Why in PL/SQL, it behaves differently and how can we enjoy the cursor of adaptation in this context?
Thank you!
My immediate thoughts were under cover PLSQL optimizations.
PLSQL_OPTIMIZE_LEVEL has no effect.
To run I had to Board BIND_AWARE and SESSION_CACHED_CURSORS value 0.
Subsequently found Randolf Geist post in the same direction:

Hello
DB version: 11.1.2.3.0
OS: OEL5
I'm trying to follow the link below, to find changes in the DB settings.
Kerry Osborne Oracle Blog"Blog Archive" followed changes to parameter - Oracle Kerry Osborne Blog
But I'm not able to receive the output after you change the setting a DB - session_cached_cursors.
SQL:
SELECT instance_number instance, snap_id, TIME, parameter_name, old_value, new_value FROM (SELECT a.snap_id, TO_CHAR(end_interval_time,'DD-MON-YY HH24:MI') TIME, a.instance_number, parameter_name, value new_value, lag(parameter_name,1) over (partition BY parameter_name, a.instance_number order by a.snap_id) old_pname, lag(value,1) over (partition BY parameter_name, a.instance_number order by a.snap_id) old_value FROM dba_hist_parameter a, dba_Hist_snapshot b , v$instance v WHERE a.snap_id =b.snap_id AND a.instance_number=b.instance_number AND parameter_name LIKE NVL('session_cached_cursors',parameter_name) ) WHERE new_value != old_value ORDER BY 1,2; no rows selectedNot sure where I'm wrong.
Any help is appreciated.
TA.

you wait until a new snapshot has been taken to fill the views of HISTORY with the change?

DRCP with cx_Oracle doesn't seem to work as expected
I am trying to use DRCP Oracle 11.2 with a Python client using cx_Oracle 5.1.2.
If I create the connection by calling cx_Oracle.connect and adding a cclass argument and an argument of purity, then registration in sys.v_$ cpool_cc_stats with cclass_name set to my cclass show an increase in num_requests and num_misses for the number of calls I do with num_hits staying at 0.
connection = cx_Oracle.connect (user = db ['USER'], password = db ['PASSWORD'], dsn = db ['NAME'], cclass = db ['OPTIONS'] ['CCLASS'], cx_Oracle.ATTR_PURITY_SELF = purity)
However, if I create an instance of a cx_Oracle.SessionPool, then pass this instance in the same call to cx_Oracle.connect as an additional 'pool' argument, then num_misses goes up by 1 and num_hits goes up by num_requests - 1 (I guess this means that the first application is a new connection, all the rest are using this connection).
pool = cx_Oracle.SessionPool (user = db ['USER'], password DB ['PASSWORD'], dsn = db ['NAME'], min = 1, max = 2, increment = 1)
connection = cx_Oracle.connect (user DB ['USER'], password DB ['PASSWORD'], dsn = db ['NAME'], pool = pool, cclass is purity, db ['OPTIONS'] ['CCLASS'] = cx_Oracle.ATTR_PURITY_SELF)
Is this correct? Should I create a SessionPool customer, then using them to acquire and release connections?
This article mentions nothing SessionPool. I came across SessionPool in this post, but this is not the official documentation.
FWIW, when I run select * from dba_cpool_info, I get the following:
'CONNECTION_POOL '. 'STATUS '. "MINSIZE. "MAXSIZE". 'INCRSIZE '. "SESSION_CACHED_CURSORS. 'INACTIVITY_TIMEOUT '. 'MAX_THINK_TIME '. 'MAX_USE_SESSION '. 'MAX_LIFETIME_SESSION '. 'SYS_DEFAULT_CONNECTION_POOL '. 'ACTIVE '. 4 40 2 20 300 120 500000 86400 The first way to connect to drcp has a bug and fix is added soon.
The second connection using SessionPool shows expected results.
In both cases, the behavior should be the same. NUM_HITS is expected to increase and NUM_MISSES should not increase if purity itself and class connection is used to connect to the DB.

Hello
If you have a valid license of Oracle support, I suggest that you raise a service request with the support of the Oracle.
This could probably be a bug and it is determined to be a bug, you must upgrade your database to a version more supported, since 10.2 is out of taken in charge for some time.
Kind regards

Where should I start in order to solve this problem.
I don't know why are you fndsm missing entry tns. AutoConfig should have created the tnsnames.ora with this entry.
Assuming that the architecture you have is
clodb - only db level
cloapp - applications (cm, forms, apache)
1. check if you have the correct entry for FNDSM_CLOAPP_PROD tns in tnsnames.ora on the application tier
2. make sure that apps listener is running
If it does not, the cleaner way than it would be to:
1. stop all application services
2. run exec fnd_conc_clone.setup_clean (); only applications
3. run autoconfig on dbtier
4. run autoconfig on level apps
Check fnd_nodes, you should have entries for the nodes and the check tnsnames.ora, should have entered correct tns.
5 start services.
Thank you

automatic failover - failover unable
Hi gurus,
I have expirienced strange behavior of automatic failover of data guard.
According to the Observer newspaper failover failed:
Observer began

16:00:07.44 Thursday, February 20, 2014

However according to primary alerts of new ipcblna2 journal:

Thank you
Hi oraman,
You can check the broker for this config. Connect to the database with dgmgrl and get the config database:
See the verbose XXX database;
The parameter 'StaticConnectIdentifier' will tell you what data Guard Broker expects to find when it needs to restart a database. You must create a static entry to the listener with the service_name in this setting.
Make sure you have the "SERVER = DEDICATED" in the connection string. If you set this explicit, default oracle shared a connection via the server connection, which could cause your question.
Concerning
Thomas

Your choices are limited-
1. modify the code to include ORDER BY (is that an application packaged or home grown? If the first case, have you contacted the seller?)
2 stay on 9.2.0.8 and do not update to 10 g +.

Fix the activation parameters for caching the results of the customer? No performance gain
I gathered and made every detail I could search. I use Oracle EE 11.2 g 32-bit on Windows 7 64 bit
But despite I activate client caching result, I see no difference response API despite I have remote, connect to the server on LAN 1Gbit network
I see > difference 1 sec only when you enable caching of server (2nd opening files 300% faster 57 dry-> 18 s) and 32 MB are cached for the opening.
I don't know how to see the client_result_cache except the network traffic, detours, IO
MEASURES_
* 1.* I activated the parameter setting Statement Caching on the client and dbhome and set it equal to my ora.ini file OPEN_CURSORS (300) the registry as possible. And rebooted the system, of course.

-Is everything OK? Why not better time response then?
The LAN 1Gbit 1 customer is perhaps too fast anyway, and I should try via internet or something?
Hope that you have an idea, I can't search to find or think of something.As said by John, SQL * Plus does not implement caching the result to the client. You write an application for OIC (or another application that knows the OIC calls appropriate to make) that implements the setting cache the result of the customer.
Your test is behaving as expected.

Values recommended for installation of PROD init.ora
Hi all
I want to put in place an 11g database. The specifications of the server is OEL 5.6 with 12 GB of Ram and a Quad Core processor.-Assuming that I am using a 64-bit version of Oracle, -that there is nothing else running on the server, -that there will be no other databases on the server, -that I have substantially more data on disk than I have RAM, -and that I am using 11g.
There will be 200 users simultaneously access the database. I understand that 10g and 11g are 'auto adjustment '.
So in this respect that I still have to change the values in the default init.ora?
Can you give me example of your init.ora PROD template?
Or maybe since my RAM is 12 GB, I put just the 'target LMS = 8 GB' and the database will be good?
Thank you
YX

Addition of the assumptions of JustinImportant parameters in the production will be
AUTO TUNE MEMORY_TARGET SGA AND PGA
will be better take notice of v$ pga_target_Advice, v$ sga_target_Advice, v$ memory_target_Advice
This will help you you also for memory management http://docs.oracle.com/cd/B28359_01/server.111/b28310/memory003.htm
SESSION_CACHED_CURSORS
Oracle monitors the SQL statements that are submitted for each session. If it detects that the same statement has been presented several times, it moves of the statement in the cursor cache and leaves the cursor open for future reuse. The parameter SESSION_CACHED_CURSORS controls the number of cursors allowed in the cursor cache.
The default value for SESSION_CACHED_CURSORS varies with the release of Oracle. If your instance is not configured to cache at least 50 sliders, increase the value of this parameter to 50.
OPEN_CURSORS
The Oracle OPEN_CURSORS initialization parameter specifies that the number of cursors a session can have open at any time. The default value is 300. If the session is trying to open a new cursor, but already the number maximum open cursors, the error Oracle-1000 will be returned.
Parameter that affects the Oracle statistics
OPTIMIZER_MODE keep the default value for the parameter Oracle OPTIMIZER_MODE. For Oracle9i, the default is to choose; for Oracle 10 g, it is all_rows.
The RAM management
PGA_AGGREGATE_TARGET
SGA_TARGET
ALSO UNDO_RETENTION VA BE IMPORTANT SEE http://docs.oracle.com/cd/B19306_01/server.102/b14237/initparams222.htm

OIM 11 g R2 installation question. Failed to create schema of the IOM by using RCU 11.1.2
I tried to install OIM 11 g R2 on a Windows 2008 R2 64-bit server and were met the following error during the creation of diagrams of IOM. Other patterns, such as metadata, SOA, user's email services and other associated schema creation succeeded. But creating schema IOM took more than 2 minutes and finally it fails with the error below.
################################################################
UCR-6130: Action failed
UCR-6135: error when trying to execute the action of java.
################################################################
Components used:
OS: Windows Server 2008 R2 64 Bit
DBS: 11 GR 2 (11.2.0.1)
UCR: 11.1.2
The first error was ora-12637 package receive failure followed by Table or view does not exist. I couldn't get much information from the IOM and the rcu.log.
I put the processes and the open_cursors session_cached_cursors described in preinstalling OIM 11 g R2 installation step.
Pointers on what will be highly appreciated.
Thank you
SriniCopy the msvcr71.dll rcuHome\jdk\jre\bin inside the installer of the UCR and paste in C:\Windows\SysWOW64.
Try to rerun the rcu with the new user, i.e. instead of DEV_OIM, run it with DEV_OIM1.
Or delete the user DEV_OIM first and then use the same user.

Hello
my Oracle DB is 10.2.0.5 version
Linux Red Hat operating system
I need to change some settings in the settings file:
Some settings are below:
audit_sys_operations
AUDIT_TRAIL
compatible
db_cache_size
event
JAVA_POOL_SIZE
JOB_QUEUE_PROCESSES
LARGE_POOL_SIZE
pga_aggregate_target
process
session_cached_cursors
sessions of
SGA_MAX_SIZE
SGA_TARGET
in path $ORACLE_HOME/dbs I have these files:
init.ora
initdw.ora
spfileorcl.ora
pfileORCL.ora
orapworcl
spfileORCL.ora
What step I have to do to change these settings?
Thanks in advance!RAF Royal wrote:
Because I have 2 Oracle instance and I need to change/add any parameter on the second instance!Have you read that anything posted here? All you need to do is
sqlplus / as sysdba alter system set AUDIT_TRAIL=DB scope=spfile; shutdown immediate startupQuestion: Why not use a pfile file?
Answer: Edit a file pfile is one of several unnecessary steps when you already use a spfileQuestion: why specify scope = spfile instead of other options for "scope".
Answer: this particular setting is "unchangeable." Please see the documentation on this parameter in the reference manual. The "editable" property is shown as 'NO '. Perhaps the use of the term 'editable' oracle is a little misleading. This means that the parameter is not dynamically editable. Therefore, the scope of the ALTER SYSTEM cannot for the spfile, memory (the running instance).Question: Why can I restart the database?
Answer: even once, this particular parm is not dynamic. Therefore, it requires a restart of the database to pick up the change after the spfile has been changed through the ALTER SYSTEM... SCOPE = SPFILE command. -

HariWhy not just increase the size of your shared_pool_size parameter? It is not very big at the moment, maybe make 1 G.
And while you're at it, you need to sort the PGA. You have the overall goal set at less than 1 G, and at the same time you have set the limit of session pgamax_size to more than 1 G, which is impossible.
