SQL & PL/SQL :: Bundle Commands Sent At One Time?
Jun 8, 2010
I bought Selftestsoftware for 1z0-147 for 9i and 10g. Selftestsoftware is endorsed by Oracle, should be high quality. But its below sample question and answer seem to be wrong, or I could not understand it properly. It says "Network traffic is not decreased by bundling commands. Executing procedures and functions stored in an Oracle Developer application will process each PL/SQL statement and pass each SQL statement across the network to the database to be processed, dramatically increasing network roundtrips."
But PLSQL online reference manual says "However, with PL/SQL, an entire block of statements (bundling commands?) can be sent to Oracle at one time."
Selftestsoftware says pass each sql statement, but PLSQL online manual says send an entire block of statements like below diagram. Now which one is right, or I misunderstood something?
(I cant post the diagram from PLSQL online manual because of my quota)
Procedures and functions can be created and stored in the database or in an Oracle Developer application. How is performance improved when storing procedures and functions in the database?
Network roundtrips are reduced.The object code is created during execution.Network traffic is decreased by bundling commands.The source code is stored externally, and the object code is stored internally.
Explanation:Network roundtrips are reduced when storing procedures and functions in the database. The source and object code of database stored procedures and functions are stored like other objects, in physical files assigned to the appropriate tablespace. When executed from a client application, they require only one call. Because the object code is stored on the database side, there is no need to send it across the network.The object code is not created during execution. The object code is created when creating the procedure or function and is stored in the database.Network traffic is not decreased by bundling commands. Executing procedures and functions stored in an Oracle Developer application will process each PL/SQL statement and pass each SQL statement across the network to the database to be processed, dramatically increasing network roundtrips.The source code is not stored externally. The source code and object code are stored in the database.

I'm writing on behalf of the MacPorts package management system. I am trying to update the MacPorts port of Oracle Instant Client from 10.2.0.4.0 to 11.2.0.3.0 [URL}...and while many of our ports including the PHP oracle module continue to work fine with this version, soci [URL}.... and TOra [URL]...
ld: can't link with bundle (MH_BUNDLE) only dylibs (MH_DYLIB) for architecture x86_64
This is on OS X 10.8.2 compiling with Xcode 4.6's version of clang ("Apple LLVM version 4.2 (clang-425.0.24) (based on LLVM 3.2svn)").I suspect this is because soci and TOra are doing something with static libraries, and Oracle Instant Client is only shipped as a dynamic library. But I can't explain why this worked with 10.2.0.4.0, unless something has changed about how Oracle Instant
Client is being built. It's not clear whether this is an intentional change in Oracle Instant Client, and if it is, what developers should do to fix their software.I have not heard back from the developers of TOra, and the developers of soci

I got a situation to develop a complex query. Here is the scenario. I have to pick all the continues range of values into one bundle. like in following example, rows having values between 20 to 25 should have one bunch and 27 to 28 should have another as there is no from or to value from 25 to 28. with q1 ( select 20 as Frm, 25 as tto from dualunion allselect 20 as Frm, 21 as tto from dualunion allselect 20 as Frm, 22 as tto from dualunion allselect 20 as Frm, 20 as tto from dualunion allselect 21 as Frm, 22 as tto from dualunion allselect 28 as Frm, 28 as tto from dualunion allselect 27 as Frm, 28 as tto from dual)select * from q1;

My client asked me to "apply the newest patch" on his RAC 10.2.0.5 environment on Windows.
I've downloaded 10.2.0.5 Patch 20 (the newest version).
My question is: Should i apply it using OPatch to both: ORACLE_HOME and CRS_HOME? or only in ORACLE_HOME? What with 10.2.0.5.2 CRS Patch? Should i apply earlier CPU patches?

I have a 2 node RAC environment (11.2.0.3) where each node has there own local Grid_home and RDBMS_home.
I am installing a Rolling Bundle Patch with OPatch in this environment. The installation document says that "The order of patching in RAC install is GRID_HOME, then RDBMS_HOME" so i did the following.
1. stopped all oracle related services on node1
2. set oracle_home=<Grid_home>
3. applied the opatch
4. opatch succeeded on node1 and it says "The node 'NODE2' will be patched next... Is the node ready for patching?
1. Should i shutdown the oracle services in Node2 and continue to patch the Grid_home ? If yes then the DB will be completely down for user access. This defeats the purpose of rolling mode which says there is no downtime.
2. Should i patch the RDBMS_home on node1 , start all the oracle services on node1 , stop the oracle services on node2 and then resume the opatch on node1 which is waiting to patch the Grid_home on node2 ?

I am trying to trouleshoot an issue with Oracle and want to see what commands are being sent by by process. By reading the documentation it appears there is client logging to do this but I can not get it to work. I added the following commands to my SQLNET.ORA file but no log file is created:
tnsping.trace_directory = C:appproduct11.2.0client_4
etwork race
tnsping.trace_level = admin
trace_level_client = user
trace_directory_client = C:log
log_directory_client = C:log
trace_unique_client = on
trace_timestamp_client = on
Ths TNSPING works just fine it logs the information I expect. The client logging, however, never creates a file .

I'm trying to apply a patch using opatch but I'm getting this error:
"OPatch was not able to find OUI jars to load them runtime. Please provide valid oui location using 'oui_loc' option. OPatch failed with error code 255".
Oracle is 11.2.0.3 x64 on Windows Server 2008R2 x64. The PATH variable have
%ORACLE_HOME%OPatch, %ORACLE_HOME%OPatchjlib, %ORACLE_HOME%in in it.
The only OPatch command that is working and not throwing the error is the "opatch version" command.
OPatch Version: 11.2.0.3.5 OPatch succeeded.
No luck on finding issue resolution or documentation on MOS. I cannot find any documentation about the "oui_loc" option.

I am using Oracle 10g Express Edition on Fedora core 5 32+ bit os. The problem is when I use the SQL Plus command line to make SQL statements I can not get the previously typed command back at the prompt when I use the up and down arrow keys on my keyboard. This is quite easy when I am using a shell, but here with this Oracle command line interface it is not working at all. Here is the example as what actually is happening whe I press the up or down arrow keys.
SQL> drop table mailorders;
Table dropped.
SQL> ^[[A^[[A^[[A^[[A^[[A^[[A^[[A^[[A^[[A^[[A^[[A^[[A

I have a RUN file within a script to duplicate a database. As part of this RUN file I also run the command configure controlfile autobackup off; as part of this RUN file. However, this command has turned off backup of the control file on the AUXILLARY database (i.e. production) as well as the TARGET database (test). Is this supposed to happen?
My run file is:
rman TARGET sys/XXXX@${DB}-SOURCE AUXILIARY /
RUN {
allocate AUXILIARY channel a1 type disk;
allocate AUXILIARY channel a2 type disk;
allocate AUXILIARY channel a3 type disk;
allocate AUXILIARY channel a4 type disk;

I have a table which stores apointment start times and appointment end times. For the sake of this thread I will call them appt.start_time and appt.end_time. I then have a check in time and a check out time for the customer. The only thing is they ONLY way to distinguish between a check in time and a check out time is which one has the earlier time and which one has the later time. Obviously the earlier time will be the check and the later time will be the check out.
This is fine, however sometimes they may forget to check a person in or out and I need to determine whether the time should be insert into the check_in column or the check_out column. To do this I was thinking of comparing the time with the appointment start and end time and if it was closer to the appointment start time put it into the check_in column and if its closer to the appointment end time put it into the check_out column. But I was wondering how I would go about doing this.
The time I will want to compare against the appointment start and end time I will store in a variable called v_time and have this as part of my query, im just unsure of what way to write the query so as to check if the time is closer to the start or end time.

select asl1.agentsessionid as sessionid1, min(asl2.agentsessionid) as sessionid2
from cti.agentsessionlog asl1
[code]...
As you can see from my where statement I want to compare the endtime with the startime. This query returns zero results. Is there a way to write the where statement different so I can have results?

We have a Oracle 10g database with RAC and Dataguard. When we look at the AWR report, the wait time shown by Oracle for this database is very high.
Service Time : 15.36%
Wait Time : 84.64%
This would imply Oracle is waiting for resources 85% of the time and only processing SQL queries during 15% of its non-idle time. However when we check the OS (RHEL), the iowait is only about 10% and the CPU is 80% idle. This means that that processing horsepower is available.
As such, the results between the OS and Oracle database (AWR report) seems contradictory. OS says we have CPU/IO capacity, however Oracle says we don't.

I'm using Oracle 11g and I have a bunch of indexes and I want to check if they are being used. I just ran my workloads and now I want to see when each one was last used so I can see if it was during my timeframe or not.
After I ran my test, I found the below, but since I did not enable this, plus I have many indexes.
--Monitor an index to see if it's used
alter index SAMPLE_INDEX monitoring usage;
select * from v$object_usage where index_name = 'SAMPLE_INDEX';
alter index SAMPLE_INDEX nomonitoring usage;
