I have a problem with fetching SQL plans.
In the final form, I have to fetch them through PL*SQL.
So I have a bash script, a loop to iterate through sql plan names and parameters, and a code like this:
sqlplus -s /nolog > /dev/null 2>&1 <<EOF
CONNECT BLAH/BLAH#BLAH
*CLEAR AND SET COMMANDS HERE*
VARIABLE RC REFCURSOR;
SPOOL ${BERICHT}_${configArray[0]}.DATA
SET TIMING ON;
EXEC :RC := $aktuellesBericht;
SET TIMING OFF;
PRINT RC;
DISCONNECT
QUIT
EOF
And the second part: (logging in as SYS, but without the SYSDBA permissions, I dont have them and I dont think that I will have them...)
sqlplus -s /nolog > /dev/null 2>&1 <<EOF
CONNECT SYSBLAH/SYSBLAH#BLAH
SPOOL ${BERICHT}_${configArray[0]}.SQLPLAN.TXT
CLEAR BREAK
CLEAR COMP
CLEAR COL
select
sqlplan.operation,
sqlplan.options,
sqlplan.object_name,
sqlplan.cost,
sqlplan.depth
from v\$sqlarea sqlarea,
v\$session sesion,
v\$sql_plan sqlplan
where sesion.sql_hash_value = sqlarea.hash_value
and sesion.sql_address = sqlarea.address
and sqlarea.plan_hash_value = sqlplan.plan_hash_value
and sesion.username = 'BLAH' order by sqlplan.depth;
QUIT
EOF
All I can get from this is *.SQLPLAN.TXT files containing just one sentence: no rows selected
What is strange here, that when I do the same in PL/SQL Developer - i get the same results, BUT when I just click on the Auto Refresh timer button on both SQL windows, both queries are running in parallel, and SOMETIMES the second query (the one to fetch SQL plan) is giving me results. And sometimes it doesnt.
It seems that theese commands need to be run in parallel... or am I missing something?
The sql query in my question was never needed.
All I needed is to write to the admin team to grant me the SELECT premissions on:
V$SQL_PLAN, V$SESSION and V$SQL_PLAN_STATISTICS_ALL
The answer to my question was found here.
I will need a deeper understanding of the problem in the future but for now, FWIK, looking deeper into the dbms_xplan package gave me the idea.
The approach to get the queries from the SYSACC account was the wrong idea. This acc has access to all the queries history and it is hard and painful (if even possible) to husk out the sql plan I needed.

I have an Oracle RDS database I manage, and I need to be able to pull changes from the database for replication to another system. Once connect to the database, below is the commands I run.
EXEC rdsadmin.rdsadmin_util.create_directory(p_directory_name => 'logminerlogs');
set heading off;
set echo off;
set space 0;
set pagesize 0;
set linesize 10000;
set termout off;
set trimout on;
SET TRIMSPOOL ON;
set feedback off;
set newpage NONE;
set define on;
exec dbms_stats.gather_dictionary_stats;
EXEC rdsadmin.rdsadmin_util.alter_supplemental_logging('ADD','PRIMARY KEY');
EXEC rdsadmin.rdsadmin_util.alter_supplemental_logging('ADD','UNIQUE');
BEGIN
dbms_logmnr.add_logfile(
logfilename=> 'rdsdbdata/db/ORCL_A/arch?redolog-99999-9-9999999999.arc');
*** REPEAT for all redo logs ***
END
/
EXECUTE dbms_logmnr.start_logmnr(STARTTIME=>SYSDATE-1,ENDDATE=>SYSDATE,OPTIONS=>DBMS_LOGMNR.DICT_FROM_REDO_LOGS+DBMS_LOGMNR.COMMITTED_DATA_ONLY+DBMS_LOGMNR.PRINT_PRETTY_SQL);
Doing all of that gives me the error
ORA-01291: missing log file
ORA-06512: at "SYS.DBMS_LOGMNR", line 72
ORA-06512: at line 1
I get all of the 'arc' files by querying
SELECT name FROM v$archived_log WHERE first_time > SYSDATE-1 and first_time < systdate ORDER BY 1;
I ran all of these scripts once and I was able to query v$logmnr_contents and get the results I wanted. When I opened another SQLPlus window and ran all of the scripts again, I get the error of Missing Log File mentioned above.
I'm not exactly sure what I am doing wrong here. I have also tried
DBMS_LOGMNR_D.BUILD(dictionary_filename=>'lgmnrdict.ora',dictionary_location=>'LOGMNRLOGS');
where LOGMNRLOGS is a dictionary folder I created previously, and then instead of the redologs when calling add_logfile I point to the 4 onlinelogs .log files that exist on the database and then run command
EXECUTE DBMS_LOGMNR.START_LOGMNR(dictfilename=>'/rdsdbdata/userdirs/o1/logmnrdict.ora');
This will start Logminer, but when I make any changes and commit to the database, when I query v$logmnr_contents those changes are not being returned.
I realize I might be rambling at this point, but I feel like I am very close to the solution; I'm just missing something. Any help is appreciated.
The problem was that for each add_logfile command, I was setting options for dbms_logmnr.new for each rather than for the first and all remaining redologs using dbms_logmnr.addfile.
I have one script script.sql which I want to execute from command line using oracle and passing it two parameters, as shown below
sqlplus user/pass # script.sql my_parameter1_value my_parameter2_value
What should it be in script.sql in order to be able to run it with the parameter values?
The solution can be prepared looking at oracle blogs:
https://blogs.oracle.com/opal/sqlplus-101-substitution-variables#2_7
For the question above, the solution would be to create a script.sql like this:
DEFINE START_VALUE = &1;
DEFINE STOP_VALUE = &2;
SELECT * FROM my_table
WHERE
value BETWEN &&START_VALUE AND &&STOP_VALUE;
I wanted to run a script that would return all orders raised during the last seven days. Here's how...
the script
SELECT * FROM orders_detail WHERE order_date BETWEEN '&1' AND '&2';
EXIT;
the command
sqlplus ot/Orcl1234#xepdb1 #"/opt/oracle/oradata/Custom Scripts/orders_between_dates.sql" $(date +%d-%b-%Y -d '-7 days') $(date +%d-%b-%Y)
Hope that helps someone. Luck.
I have a simple script in bash that just return the count of a given table
The trow command through bash its like that
user>bash Bash_Script.bsh -T MyTableTthatAlreadyExists
After the conections parameters it just do that:
SQLSTRING="SELECT COUNT(*) FROM $SYBTAB;"
BATCH_ARGS=`sqlplus -S /nolog <<SQL | tail -1
connect $ORCL_USR/$ORCL_PWD#$ORCL_TNS;
alter session set nls_date_format='YYYYMMDD';
set pagesize 0 long 4096 linesize 32767 feed off head off;
$SQLSTRING
quit;
SQL`
echo "$BATCH_ARGS"
And it works. Yest it works, it returns the nummer of rows of my table.
The problem come when I create a new table MyNewTable
- The table exists in Oracle
so when I do in SQL Developer
select count(*) from MyNewTable;
return the correct nummer.
But when I throw again the unix command. It doesnt work, it doesnt return anything
user>bash Bash_Script.bsh -T MyNewTable --> return nothing
I wonder myself what I m missing, wat I m not taking account.
I thounk about Grant privileges but they both haven the same.
can anyone here help me ?
Thanks in advance, Enrique
Your script is only getting the last line of output from SQL*Plus
BATCH_ARGS=`sqlplus -S /nolog <<SQL | tail -1
If you remove the tail part:
BATCH_ARGS=`sqlplus -S /nolog <<SQL
then you'll see what is actually happening. With a table that exists, with that modification I see:
user>bash Bash_Script.bsh -T MyTableTthatAlreadyExists
Session altered.
1815
and with a table that does not exist I see:
user>bash Bash_Script.bsh -T MyNewTable
Session altered.
SELECT COUNT(*) FROM t43
*
ERROR at line 1:
ORA-00942: table or view does not exist
It seems you are seeing ORA-01031: insufficient privileges, so the user you are connecting as needs to have select privileges granted for the new table.
As you only want the actual count, if you swap the order of the alter and set clauses the Session altered. message will also be suppressed as feedback will be switched off by then:
BATCH_ARGS=`sqlplus -S /nolog <<SQL
connect $ORCL_USR/$ORCL_PWD#$ORCL_TNS;
set pagesize 0 long 4096 linesize 32767 feed off head off;
alter session set nls_date_format='YYYYMMDD';
$SQLSTRING
quit;
SQL`
and you'd then see, for an existing table, just:
user>bash Bash_Script.bsh -T MyTableTthatAlreadyExists
1815
making the tail unnecessary anyway.
Hello i want to connect to following dbs in loop and execute statements on each:
conn support/support#sp0666to
conn support/support#sp0667to
conn support/support#sp0668to
Is there any way to do this in sqlplus?
Thank you for your answers in advance!
Create one script (doWork.sql) that contains the majority of what you want to do:
conn &1/&2#&3
select EMPLOYEE, AUTHORIZED, TIME, DAT, WORKSTATION
from EMPLOYEE
where status = 25;
In a separate script (goToWork.sql):
set lines 1500 pages 10000
set colsep ';'
set sqlprompt ''
set heading on
set headsep off
set newpage none column tm new_value file_time noprint
select to_char(sysdate, 'DDMMYYYY_HH24.MI') tm from dual;
accept user
accept pass
spool C:\Users\NANCHEV\Desktop\parked.csv
##doWork &user &pass sp0666to
##doWork &user &pass sp0667to
##doWork &user &pass sp0668to
spool off;
exit
If you want separate files, then move the two spool commands to the doWork.sql file.
Assuming you want to run the same set of queries for each database, I'd create a script file (e.g. main_statements.sql) containing those statements.
Then, if the list of databases was static, I'd create a second script file (e.g. run_me.sql) in the same directory, with contents along the lines of:
connect &&user/&&password#db1
##main_statements.sql
connect &&user/&&password#db2
##main_statements.sql
connect &&user/&&password#db3
##main_statements.sql
...
If, however, the databases are static but the list is contained in a database somewhere, then I'd write a script (e.g. run_me.sql) that generates a script, something like:
set echo off
set feedback off
set verify off
spool databases_to_run_through.sql
select 'connect '||username||'/'||password||'#'||database_name||chr(10)||
'##main_statements.sql'
from list_of_databases_to_query;
spool off;
##databases.run_through.sql
N.B. untested. Also, I have assumed that your table contains the usernames and passwords for each db that needs to be connected to; if that's not the case, you'll have to work out how to handle them; maybe they're all the same (in which case, you can hardcode them - or better yet, use substitution variables (e.g. &&username) to avoid having to store them in a plain file. You'd then have to enter them at runtime.
You'll also need to run the script from the same directory, otherwise you could end up with the generated script not being created in the same directory as your main_statements.sql equivalent script.
Yes it's possible, you can use oracle DBLink to connect to different dbs just like your example.
I am trying to execute a dynamic plsql command in a remove machine (say 192.168.x.x) and get it's return value to local machine from where I initiate shell script. I am testing two approaches to do this. But none of them seems to work properly.
Approach - I
in this approach if i supply values for ssh and sqlplus (login user/ip and schema user/ip) via shell variable it won't work. working code with hardcoded value is below.
#!/bin/sh
varfld="SYSDATE"
retVal=`echo "SELECT $varfld FROM dual;" | ssh utility#192.168.x.x 'sqlplus -S utility/pwd' | tail -2 | head -1`
echo "return value 1: "$retVal
Approach - II
In this approach I can pass everything i need in a variable. But the plsql command (i.e value of variable $ssh_execute_command) is not recognized inside plsql. Only hardcoded plsql command gets executed.
P.S.This works fine with vsql with few modification to connect Vertica.
v_server_user=utility
v_server_name=192.168.x.x
ssh_v_schema_name=utility
ssh_v_schema_pwd=pwd
varfld="SYSDATE"
execute_command="SELECT $varfld FROM dual;"
retVal=$(ssh $v_server_user#$v_server_name ssh_v_schema_name=$v_schema_name ssh_v_schema_pwd=$v_schema_pwd ssh_execute_command=\""$execute_command"\" 'bash -s' <<SSHSQLTEXT
sqlplus -S $ssh_v_schema_name/$ssh_v_schema_pwd
SET ECHO OFF
SET HEADING OFF
SET FEEDBACK OFF
SELECT SYSDATE FROM dual;
SSHSQLTEXT
)
echo "return value 2: "$retVal
Queries
1. How can we make sql command passed in a variable make work inside pqlplus? or
2. How can we pass required values for ssh and sqlplus (login user/ip and schema user/ip) dynamically and make it work?
The sql statement "SELECT SYSDATE FROM dual;" used here is for testing purpose only. I will be calling package function instead to get return value. And this is yet to be tried in any of these scenarios. If anyone could address that too with example, that would be great!
Thanks in advance.
You need to assign the result of sqlplus to a variable which must be displayed within ssh so that the result is passed to variable retVal. Try the following code:
retVal=$(ssh $v_server_user#$v_server_name ssh_v_schema_name=$v_schema_name ssh_v_schema_pwd=$v_schema_pwd ssh_execute_command=\""$execute_command"\" 'bash -s' <<SSHSQLTEXT
sqlresult=`sqlplus -S $ssh_v_schema_name/$ssh_v_schema_pwd <<EOF
SET ECHO OFF
SET HEADING OFF
SET FEEDBACK OFF
SELECT SYSDATE FROM dual;
exit
EOF`
echo $sqlresult
SSHSQLTEXT
)
echo "return value 2: "$retVal
If you execute the above block of codes, you will have the sysdate as result in $retval
