SQL Plus backend process

Suppose I execute a query from SQL Plus.
Now this query takes long amount of time to execute. If I close the SQL Plus session does it also terminiate the process on the Oracle server.
If not than in this case, if want to terminate the query processing what shall I do?
Thanks in advance,
Raja.

if you close sqlplus it doesn't necessarily terminate the backend process immediately.
you should use the ALTER SYSTEM KILL command (it's documented in the manuals)

SQL PLUS In Process Flow

Hi
Im Trying to include run a sql script thru Process flow.
Am giving the connection specification as
/oracle/oracle10/bin/sqlplus schema_name/password@DB
followed by the copy command...
While executing am getting the error as

you cannot put the copy command (or any commands) after the user/pass
make a sql script with your copy command
run_copy.sql:
copy...
exit

Maximum length of SQL*Plus Command?

I'm typing a long query into SQL*Plus (Linux, version 9.2.0.1... yes, I know it's ancient).
If I run this query, all works fine:
select 'update myauditing_table set test_details='''||grantee||''' where myaudit_refno=''A.FE'';' from (select case when upper(value) in ('DBO','TRUE') then (select agg_concat(grantee) from dba_tab_privs where table_name='AUD$')
else (select 'AUDIT_TRAIL is set to: '||value from dual) end as grantee from v$parameter where upper(name)='AUDIT_TRAIL' order by grantee);
'UPDATEMYAUDITING_TABLESETTEST_DETAILS='''||GRANTEE||'''WHEREMYAUDIT_REFNO=''A.F
update myauditing_table set test_details='AUDIT_TRAIL is set to: DB' where myaud
it_refno='A.FE';(In other words, is SQL that generates other SQL: if AUDIT_TRAIL is set to something interesting, tell me who has access to the AUD$ table. And it's working fine... the agg_concat function mentioned is simply Tom Kyte's stragg function under another name, as lifted word-for-word from http://www.sqlsnippets.com/en/topic-11591.html)
Now this is what happens if I take out the linebreak after the mention of AUD$, so that the command is submitted as one single line of code:
SQL> select 'update myauditing_table set test_details='''||grantee||''' where myaudit_refno=''A.FE'';' from (select case when upper(value) in ('DBO','TRUE') then (select agg_concat(grantee) from dba_tab_privs where table_name='AUD$') else (select 'AUDIT_TRAIL is set to: '||value from dual) end as grantee from v$parameter where upper(name)='AUDIT_TRAIL' order by grantee);
SP2-0734: unknown command beginning "s set to: ..." - rest of line ignored.The error message indicates that the text has been 'split' at the 'AUDIT_TRAIL is set to...' bit, so that "s set to" is being treated as a new command, which is of course syntactically invalid. There is definitely no other change in text between the two versions, apart from the removal of a carriage return before the "else" statement.
Possibly a coincidence, but the first "s" in "s set to" appears at position 258 in the entire text... close to a possible 255 or 256 character limit, perhaps?
The same problem happens whether I run the command as a script (@mysql.sql) or typed in directly into a client SQL*Plus session. Is there some inherent limit to the length of commands that SQL*Plus can process in this version? My code runs fine on 10g and 11g databases/clients, whether it's on one line or two. Anyone know of a bug in 9i regarding this? And if there's a workaround (other than the obvious one of upgrading, of course!)

As mentioned, it's choking at the 258th character, not the 240th. Also, it's a SELECT statement, not a COPY command (one relates to the database, the other is an internal SQL*Plus feature). And someone else also kindly pointed out that SQL*Plus has a command limit length (i.e., database-related commands) of 2500 characters. So I don't think that's the issue.
I can be a bit more specific about this one now, though. I've a sequence of Solaris boxes running 9.2.0.1 up, and the results are that 9.2.0.1 is affected; and it's a problem for 9.2.0.7:

SP2-0734: unknown command beginning "s set to: ..." - rest of line ignored.But in 10.2.0.1, the problem disappears.
I am not sure, but it is perhaps related to metalink note 285913.1, since we did get some ORA-00600: internal error code, arguments: [qernsRowP], [1] errors in the alert log with a slightly different version of the above query. Changing the query obviously alters the test, though, so it may be completely unrelated.
Either way, I think it's definitely a version-specific SQL*Plus bug (though it would be nice if any other 9i owners out there could try it and report back!)
Anyway, the workaround is simply to submit the command on two separate lines, wherever possible. And of course... to upgrade.

SQL*Plus Change to File While Being Run

Anyone,
Once you execute a file run in SQL*Plus does the entire file get cached by SQLPlus? (i.e. @C:\temp\myfile.sql)
If I change the file C:\temp\myfile.sql while the session is running (long runing script) will it take effect or not?
I was able to open the file make a change and save but not sure if SQLPlus will pick up my change when it gets to the point in the script where I made the change. Since it was already running.
Thanks,
Miller

That is a very bad idea to begin with.
If you made a change at the location that has not yet reached by the SQL*Plus script processing, you could see those changes (again depending upon where and how you do them).
But in most circumstances, the results will be unpredictable (most likely with error messages) since you cannot control what part of the script the SQL*Plus application is currently executing at the moment you decide to make change to the script.
For example, I started with this script:
REM --- Script start ---
prompt "Waiting ..."
begin
dbms_lock.sleep(20) ;
end ;
begin
dbms_output.put_line('This is text') ;
end ;
prompt "Finished..."
REM --- Script end ----And run this within SQL*Plus. While the PL/SQL block was waiting on the sleep call, I removed the first line of the script (the one that starts with the prompt statement) and saved it. Below is the output from this run:
SQL> @test
"Waiting ..."
PL/SQL procedure successfully completed.
SP2-0734: unknown command beginning "ut_line('T..." - rest of line ignored.
SP2-0042: unknown command "end " - rest of line ignored.
PL/SQL procedure successfully completed.
"Finished..."
SQL>I would not consider this as a successful completion of the script.
At this point, you are probably playing with probability and taking chances.

How to start/stop process flow from sql*plus?

Hi,
i know how to start a process flow via sqlplus_exec_template.sql, but i cannot find any information on how to stop (and rollback) a working flow from sql*plus. Any help would be appreciated.
Greetings

Hi,
I've had a go.
How should I interpret the results of list_requests:

Whilst a process flow is executing the last query will list executions, all of which have status BUSY:

owner_owr@ORKDEV01>
As an aside, I will attempt to get rid of the READY deployment and deployment unit using deactive_deployment.sql
Now, if I attempt to use deactivate_execution.sql on any of the executions with status BUSY I get:
owner_owr@ORKDEV01> @deactivate_execution
Voer waarde voor 1 in: 396136
declare
FOUT in regel 1:

ORA-06512: at "OWNER_OWR.WB_RT_EXECUTION", line 90
ORA-06512: at line 4
owner_owr@ORKDEV01>
So all the seems to remain is to use abort_exec_request.sql
This does the job, but the script itself hangs.
I think it has to do with the l_stream_id not being checked again after the initial IF. I think it should probably be part of the loop condition as it is again reset in the do_acks inside the loop.
Cheers & thanks,
Colin

Can we use xml Publisher reporting for sql* Plus in EBS

Hello All,
The current report is designed in Sql* Plus Executable report and the output is in txt format, Now the requirement is to have the output in Excel format.
So is it possible to use the xml reporting and make the output as Excel from the word template we design from MSword as we do for rdf(I have done few reports created in rdf to xml publisher reports in EBS and stand alone as well.).
Do the same procedure will suit for Sql*Plus reports tooo or Is there any work around to achieve this.
Thanks and Regards
Balaji.

Hi
Thanks for the reply..
I tried to do the follwoing
1. changed the output to xml in the conc. prog.
2. ran the same report but i am getting the follwoing error in the output file
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
Invalid at the top level of the document. Error processing resource
Other reports which are using the Oracle Reports(rdf) as source, i am able to generated the xml as expected....
So my question is whether we can use sql* reports executable and generate xml in the conc.prog.
if any one has used the sql*reports for xml publisher reporting... please let me know, so that if its possible i will check my sql needs some validation or tuning...
thanks in advance
Balaji.

In the document 294932.1 Section 4 there are no pre-installation patches or update for OS RedHat LinuxAS4.
When I type echo $LD_ASSUME_KERNEL it doesn't display any value so do I need to set the LD_Assume_Kernal value manually.
If yes, please let me know the path and command to set the kernel value.

Connect via SQL*Plus taking more time in Oracle 11 than in 10

NLSRTL Version 10.2.0.4.0 - ProductionOS is AIX 5.3 for Oracle 10 and AIX 6.1 for Oracle 11.
We are currently in the process of migrating some applications from Oracle 10 to 11. Our admins have setup a new development system for us with an Oracle 11 instance. Regarding performance the new system behaves more or less the same than our old, e.g. when executing SQLs we notice hardly any performance differences and those we find are slightly in favour of the new system.
But now we discovered that the time it takes to establish a database connection via SQL*Plus is longer on the Oracle 11 system. Running the following code
sqlplus -s user/pw@database <<END
quit
ENDa thousand times takes ~60s under Oracle 10 but ~140s under Oracle 11. This may not seem much but we are running a test framework consisting of a bunch of shell scripts where several thousand connections are openend via SQL*Plus to execute some SQLs, so that even this small time difference results in rather huge difference in total runtime. The SQLs themself require roughly the same time in both databases, as already mentioned above they are in fact slightly faster in Oracle 11.
To analyze the time difference I ran a trace for the connect with the following parameters in sqlnet.ora
TRACE_LEVEL_CLIENT=4
TRACE_UNIQUE_CLIENT=ONand found out that there is a time difference of about 70ms during the connect handshake:

With local connections - I do not think a TCP packet send from an IP to the same IP, leaves the interface as an actual wire protocol/signal. If I'm correct, then running local connection tests will be mostly useless in checking the actual network infrastructure.
Tests 3 and 4 should be showing the same connection times as the same physical network infrastructure is used - only the direction is reversed in the tests.
I would assume that port settings on the switches and interface settings on the routers treat packets equally in both directions between 2 servers. But this could in part explain the problem if this is not the case. In a case of a router for example, the 1st test's ingress interface is the egress interface of the 2nd test (and vice versa). Configurations can differ substantially between interfaces on the same router. Likewise if there is a firewall - as different rule sets are applied in each test and these rule sets could differ.
So I would not be too quick to state that this is definitely not a network problem. But I agree that based on the small percentage difference (assuming comparable tests), it does not look like a network issue.
The next step is to determine what the delay is between the listener accepting the client connection, and the connection being serviced by a dedicated server process.
This will require listener tracing - tracing the time from when the listener accepted the connection (and parsed the TNS connection string), to handing off the connection to the dedicated server process.
As a comparison test, you can also test shared server connections. Dispatcher processes (of the db instance) register themselves with the listener. The shared server client hand off is thus done to an existing server process - no need for the Listener to make a kernel call to load and initialise an executable image.
Shared connections are typically faster than dedicated connections in this respect.
If there is a major time difference, then it means some kind of issue with the listener dealing with dedicated servers as oppose to dispatcher hand off's. As both connections would have had very similar network transit time - which means the connection time difference is related directly to dealing with a dedicated server connection request and hand off.
You can also substitute the oracle executable with a wrapper - and troubleshoot the actual dedicated server startup. I've only done this with Oracle XE 10.2 though and with local IPC connections. Unsure how robust this will be for testing purposes via TCP using 11g.

Is the SQL * Plus Worksheet included in the Oracle 10g Express Edition?

Hello All,
I need to install Oracle 10g for a SQL class that I will be taking this year. I will be installing it in my laptop (Pentium 4, 1GB RAM). I was told by the Professor that I needed to have the SQL*Plus Worksheet. I would like to know which version of Oracle do I need to install, and If it includes the SQL*Plus Worksheet.
This is my first time working & installing Oracle, so I would appreciate if anyone could guide me thru this process.
Thanks a lot,
Ed

No, it is not included.
However, the same functionality, and more, is in Oracle SQL Developer - also available free and download-able from the same area as Oracle Express Edition.
Ask your prof why he want Worksheet. If it's only for the ability to scroll and correct previous SQL (eg: easier time correcting mistakes), and loading scripts, ask if SQL Developer would be allowed. It's much superior and allows you to use XE, which will not sink your laptop like the EE version will.

AUTOTRACE stats different in SQL Developer vs SQL Plus

Using SQL Developer 3.2.20.09, database is 11.2 on Linux. I'd like to know why I get different stats when using AUTOTRACE in SQL Developer vs SQL Plus. If I do the following in SQL Developer and in SQL Plus I get a very different set of stats:
set autotrace on
select * from emp;
set autotrace off
I run this with "run worksheet" in SQL Developer and I see this set of stats:
Statistics
4 user calls
0 physical read total multi block requests
0 physical read total bytes
0 cell physical IO interconnect bytes
0 commit cleanout failures: block lost
0 IMU commits
0 IMU Flushes
0 IMU contention
0 IMU bind flushes
0 IMU mbu flush
I do the same in SQL Plus and I see these stats:
Statistics
0 recursive calls
0 db block gets
7 consistent gets
0 physical reads
0 redo size
1722 bytes sent via SQL*Net to client
519 bytes received via SQL*Net from client
2 SQL*Net roundtrips to/from client
0 sorts (memory)
0 sorts (disk)
14 rows processed
A very different set of stats. The stats in shown in SQL Plus seem to be much more useful to performance optimization over the one shown in SQL Developer. Why the different set of stats for each? Thanks.

Cross-referencing to another recent thread on this topic:
Re: set autotrace on statistics in sqldeveloper (oracle 11g) is wrong

Unable to connect to an instance using EM but connecting fine with SQL*Plus

Good morning,
I followed these steps (from the 2 Day DBA document):
1. I created a template (including database) from an instance named "orcl" using DBCA, before proceeding to create the template, DBCA informed me that the instance would be shutdown, I told it to proceed.
2. The template was created successfully.
3. I am now unable to log into the orcl instance using EM, yet I can log into that instance without any problems using SQL*Plus.
The Question: Why am I not able to connect to the instance using EM ? and what do I need to do to correct this problem ?
Thank you very much for your help,
John.

NEW FEATURE:AUTOTRACE IN SQL*PLUS 3.3(EXECUTION PLAN)

제품 : SQL*PLUS
작성날짜 : 2003-10-07
NEW FEATURE:AUTOTRACE IN SQL*PLUS 3.3
======================================
Autotrace는 SQL*Plus 3.3부터 지원하는 New feature로서 기존에는 init.ora에
SQL_TRACE=TRUE를 setting 후 얻어진 trace file을 TKPROF란 utility를
이용하여 SQL 문의 수행 경로, 각종 통계 정보를 얻었다.
그러나, SQL*Plus 3.3부터는 이것을 간단히 처리할 수 있는 방법을 제공한다.
1. SQL*Plus를 실행하여 scott user로 접속한 후, plan table을 생성한다.
#sqlplus scott/tiger
SQL>@$ORACLE_HOME/rdbms/admin/utlxplan
2. 다음에 sys user에서 PLUSTRACE란 ROLE을 만든다.
SVRMGR>connect internal;
SVRMGR>create role plustrace;
SVRMGR>grant select on v_$sesstat to plustrace;
SVRMGR>grant select on v_$statname to plustrace;
SVRMGR>grant select on v_$session to plustrace;
SVRMGR>grant plustrace to dba with admin option;
SVRMGR>grant plustrace to scott;
비고) 위의 grant 문은 client에 SQL*Plus 3.3이 install되어 있는 경우
C:ORAWIN95\PLUS33\PLUSTRCE.SQL이라는 script에 기록되어 있다.
다음과 같이 실행해 주면 된다.
1> connect sys/manager
2> @$ORACLE_HOME/sqlplus/admin/plustrce.sql
3> grant plustrace to scott;
3. 다음에는 scott user로 connect하여 작업한다.
#sqlplus scott/tiger
SQL>set autotrace on
SQL>select * from emp;
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE
1 0 TABLE ACCESS (FULL) OF 'EMP'
Statistics
389 recursive calls
5 db block gets
53 consistent gets
12 physical reads
0 redo size
1049 bytes sent via SQL*Net to client
239 bytes received via SQL*Net from client
4 SQL*Net round-trips to/from client
0 sorts (memory)
0 sorts (disk)
13 rows processed
4. 참고로 set autotrace에는 여러가지 option을 부여해 작업할 수도 있다.
예)set autotrace on => Explain plan and statistics.
set autotrace on explain => Explain plan only.
set autotrace traceonly => select된 결과는 빼고 trace만 display
시킴.
set autotrace on statistics=> sql statement execution statistics.
5. 서버 버젼과 상관없다.
Server가 7.2 version 이하일지라도 clinet에 SQL*Plus 3.3이 install되어
있으면 client에서 sqlplus 3.3을 구동시켜 server에 접속하여 위와 같이
작업하면 무리없이 작업이 가능하다.

How to return a value from sql plus activity

Hi,
I want to return a value from sqlplus activity to a processflow variable.
SQL PLUS activity has a property :"RESULT_CODE", whenever i run the process flow this value is always reurned as 0.
in sqlplus activity i have written some pl/sql block....
for example
begin
end;
exit
i want to do something like
begin
if v=100 then
return 1
else
return 0;
end if;
end;
exit
can some please tell me how can i return value from this pl/sql block to proessflow.
Regards,
RD_RBS

table ==> function
input param from table to function. ==> input mapping paramter to store the output from the mapping.
Will this now work.

SQL *PLUS issue

I have an unusual problem in SQL PLUS. When the SQL statement is a DML things go fine - no problem, BUT when the SQL statement is a DDL (like creating a database object )the process hangs. Things get more interesting ... if I open another SQL PLUS session and check out, I find that the DDL has done its task. But the first SQL session (where I issued the DDL) is still hanging. If anyone has any idea please do let me know. Any help would be very useful
Thanks
Mustafa

The dot is used as like concatenation operator in sqlplus. If you need to add characters to the end of the variabel, you use a dot. If you need to add .chars then you need two dots.
With a dot
SQL> SELECT 'Say &something.not' FROM dual;
Enter value for something: something
old   1: SELECT 'Say &something.not' FROM dual
new   1: SELECT 'Say somethingnot' FROM dual
'SAYSOMETHINGNOT
Say somethingnotand without
SQL> SELECT 'Say &somethingnot' FROM dual;
Enter value for somethingnot: something
old   1: SELECT 'Say &somethingnot' FROM dual
new   1: SELECT 'Say something' FROM dual
