Dilemma of an OCA (SQL, PL/SQL) with 4 years work-ex

Dear all,
I am an OCA(SQL, PL/SQL) and working on a enhancement/production support project (Tech: JAVA and Oracle, Func: Insurance) in my firm. I am doing quite well here and keep updating myself using oracle documentation and application functionality. But in a long term, I am confused about my career path, what should I do next? Should I upgrade myself with certification in advanced PL/SQL or should I move towards DBA activities or should I learn JAVA to be an software architect?
Personally, I have great interest in oracle database, design and implementation, what can be a career path for a software architect?
Please help.

Please help.Bringing you PL/SQL up to OCP by studying for and taking 1z0-146 is probably a straightford and low impact descision.
It may not however be in the route you wish to take your career, but it is relatively low cost and good gain.
My impression is your not currently into Java ... learning that from the bottom may be a hard process and even having learn Java than in itself does not make one a software architect.
Take a browse down all Oracle Certifications at [http://www.oracle.com/education/certification] ... certifications ... view all certifications ... but remember not all Oracle products / technologies have associated certifications.
Consider SOA or BIEE or Oracle Application Express as well

Requirement for finishing OCA - Oracle 9i SQL-PLSQL

Hi,
I am planning to give the OCA certification in SQL-PLSQL Oracle 9i.
Please let me know, after successful completion of both the SQL and PLSQL exams, do I also require to have the Oracle certified training to get the certificate from Oracle.
On the below URL
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=152
There is no such mention. Howerver for OCP, it is required to have the training.
I called up few of the test centers and they all told me that I have to undergo the Oracle training, then only I will get the certificate. However, I dont feel that I need training to clear the OCA certification Oracle 9i.
Please confirm me on the requirement of training for getting the Certificate from Oracle on succesful completion of both SQL and PLSQL exams.
Regards,
Saurabh

Regards,
SaurabhFor PL/SQL OCA you do not require training to get the certification. Nor do you for PL/SQL OCP (For a lot of OCP's you do have to have training).
- Of course Oracle would recommend ou have training.
Please note that the PL/SQL OCA and OCP certifications are non version specific.
With the best will in the world a (Pearson VUE) test center only really deals in exams, they do not deal in certifications.
However some Test Centers may also be associated with training establishments.
You may have been given mis-information for one of three reasons I can think of:
1) They may have misunderstood your question.
2) The may have genuinely not known the answer, and because DBA OCP needs training they may have thought and not checked Pl/SQL OCA needs it.
3) They may have been fraudulently trying to sell you training you did not need.
You can always book the required exams online anyway.
BUT HOLD ON A SECOND ... ;-) ... BEFORE I SLANDER PEOPLE OFF: :-) [ There's meant to be a smiley here bu it keeps disappearing ]
The link you have given is for 9i DBA OCA/OCP .... and to get the 9i DBA OCP you DO need to have training.
The certification you have asked about is (9i) PL/SQL OCA/OCP ..... and the required page for that is here .....
.... http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=155
If you look at this carefully you may be able to begin to confirm what you want.

Unable to get SQL Server Agent to run after installing SQL 2012 Standard with SP1

I am unable to get SQL Server Agent to run after installing SQL 2012 Standard with SP1. Log message is as follows:
Attempting to load library 'xplog70.dll' into memory. This is an informational message only. No user action is required.
Failed to verify Authenticode signature on DLL 'C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Binn\xplog70.dll'.
Error: 17750, Severity: 16, State: 0.
Could not load the DLL xplog70.dll, or one of the DLLs it references. Reason: (null).

Hi JFriedley,
According to your error message, there might three reasons for this issue.
xplog70.dll is corrupt, you need to check if you have any SQL Server running on same file version and same production
edition. If xplog70.dll is corrupt, you can copy it from the new server where agent is running fine to your problematic server.
Native client not installed properly. If you try applying any latest Service Pack or Cumulative Update then check if the SQL Server Agent can start, if that also doesn’t solve issue then try to reinstalling SQL Server Native client from SQL Server setup
files.
There is a similar issue about error 17750, you can review the following article.

Setting fields defined in SQL updateable report with a process

I have SQL statement defined in a SQL updateable report with hidden fields. I want to be able to update these hidden fields with values from other displayed fields on the page. How do I reference these hidden items - I have referencign them as :my_field but get and error telling me thats its underfined.

But, the reason I am doing this is because I want to format the page with 6 columns in one <TD> cell with some extra text and formatting etc - I don't want 1 column per <TD>. Thats why I am using the APEX_ITEM.TEXT so I can format the 1 <TD> the way I want it (with 6 columns it there).
In the short term can you tell me how to reference hidden fields please.
I will create the case in apex.oracle.com in the next few days to make it clearer.
P.S. see my previous post: SQL QUERY updateable report with APEX_ITEM fields to update hidden columns

·         Statistics of all large tables are upto date ?
Quick Resolution tips
1) Use Bulk Processing feature BULK COLLECT with LIMIT and FOR ALL for DML instead of row by row processing
2) Use Data Caching Technique/Options to cache static data
3) Use Pipe Line Table Functions whenever possible
4) Use Global Temporary Table, Materialized view to process complex records
5) Try avoiding multiple network trips for every row between two database using dblink, Use Global temporary table or set operator to reduce network trip
6) Use EXTERNAL Table to build interface rather then creating custom table and program to Load and validate the data
7) Understand Oracle's Cost based Optimizer and Tune most expensive SQL queries with help of Explain plan
8) Follow Oracle PL/SQL Best Practices
9) Review tables and their indexes being used in the SQL queries and avoid unnecessary Table scanning
10) Avoid costly Full Table Scan on Big Transaction tables with Huge data volume,
11) Use appropriate filtration condition on index columns of seeded Oracle tables directly mapped to program parameters
12) Review Join condition on existing query explain plan
13) Use Oracle hint to guide Oracle Cost based optimizer to choose best plan for your custom queries
14) Avoid applying SQL functions on index columns
15) Use appropriate hint to guide Oracle CBO to choose best plan to reduce response time
Thanks
Praful

I understand you were trying to post something helpful to people, but sorry, this list is appalling.
1) Use Bulk Processing feature BULK COLLECT with LIMIT and FOR ALL for DML instead of row by row processing
No, use pure SQL.
2) Use Data Caching Technique/Options to cache static data
No, use pure SQL, and the database and operating system will handle caching.
3) Use Pipe Line Table Functions whenever possible
No, use pure SQL
4) Use Global Temporary Table, Materialized view to process complex records
No, use pure SQL
5) Try avoiding multiple network trips for every row between two database using dblink, Use Global temporary table or set operator to reduce network trip
No, use pure SQL
6) Use EXTERNAL Table to build interface rather then creating custom table and program to Load and validate the data
Makes no sense.
7) Understand Oracle's Cost based Optimizer and Tune most expensive SQL queries with help of Explain plan
What about using the execution trace?
8) Follow Oracle PL/SQL Best Practices
Which are?
9) Review tables and their indexes being used in the SQL queries and avoid unnecessary Table scanning
You mean design your database and queries properly? And table scanning is not always bad.
10) Avoid costly Full Table Scan on Big Transaction tables with Huge data volume,
It depends if that is necessary or not.
11) Use appropriate filtration condition on index columns of seeded Oracle tables directly mapped to program parameters
No, consider that too many indexes can have an impact on overall performance and can prevent the CBO from picking the best plan. There's far more to creating indexes than just picking every column that people are likely to search on; you have to consider the cardinality and selectivity of data, as well as the volumes of data being searched and the most common search requirements.
12) Review Join condition on existing query explain plan
Well, if you don't have your join conditions right then your query won't work, so that's obvious.
13) Use Oracle hint to guide Oracle Cost based optimizer to choose best plan for your custom queries
No. Oracle recommends you do not use hints for query optimization (it says so in the documentation). Only certain hints such as APPEND etc. which are more related to certain operations such as inserting data etc. are acceptable in general. Oracle recommends you use the query optimization tools to help optimize your queries rather than use hints.
14) Avoid applying SQL functions on index columns
Why? If there's a need for a function based index, then it should be used.
15) Use appropriate hint to guide Oracle CBO to choose best plan to reduce response time
See 13.
In short, there are no silver bullets for dealing with performance. Each situation is different and needs to be evaluated on its own merits.

Is there a way to create SQL Dev reports with validated binds?

Is there a way to create SQL Dev reports with validated binds similar to the way user defined extensions can have <prompts> with a <value> that is a SQL statement returning a list of possible values?
This sure would make select appropriate values for binds in reports easier and less error prone.

Maybe a forum search on "Windows registry" would turn up some useful things. You're not the first to ask this. You might save yourself and everyone else some time if you'd simply do that.

Error in calling SQL plus program with parameter from Shell script

This is my Shell script. I am trying to call in the SQL plus program with the parameter and the shell script is registered as a concurrent program.
PARAMETERS=`echo $1 |tr -d '\"'`
DB_USER_ID=`echo $PARAMETERS|cut -d" " -f3|cut -d"=" -f2`
CONN_STRING=$DB_USER_ID
REQ_DATE=`echo $PARAMETERS|cut -d" " -f9|cut -d"=" -f2`

timestam=`date +%y-%m-%d`
sqlplus -s $CONN_STRING @ar_statement.sql $REQ_DATE
chmod 755 statement.sh
. statement.sh
My Sql plus program is like this.
set pagesize 0
set heading off
set feedback off
spool $GEC_TOP/log/ge_ar_statement.sh
select output_file_name
from fnd_concurrent_requests
where trunc(actual_completion_date) = '&2';
spool off;
exit;
When i run the concurrent program, i am getting the following error:
ar_statement: line 14: REQ_DATE: command not found

I am not strong at Unix Porgamming and i would request someone who can
help me out as soon as possible.
I need this solution quickly and thank everyone in advance.
Thanks.

Can you put your coding between code statements, like shown in the FAQ. It will be easier to read.
Looking at your script, my first guess is that crontab will not find your sqlplus since your script does not have $HOME/bin in the $PATH. From what I understand, running .profile in your script will not work either because variables are exported to sub-shells, not to the shell above. You can call your script with a dot like . ./script which means that the script will run like it was typed at the command prompt. But it will be less confusing to define appropriate variables in the script. eg.
ORACLE_SID=my_instance_name
ORACLE_HOME=/my_path_to_oracle_home_directory
LD_LIBRARY_PATH=$ORACLE_HOME/lib
PATH=$ORACLE_HOME/bin:$PATH
I remember some slightly different way of coding to handle the sqlplus return codes.
For instance:
sqlplus -s /nolog > /dev/null <<-EOF
connect system/manager
@ssm.sql
whenever oserror exit failure
whenever sqlerror exit failure
EOF
sql_err=$?
if [ $sql_err -ne 0 ]; then
echo "FAILURE"
else
echo "SUCCESS"
fiThe - in -EOF supresses tab's
Using connect will prevent ps from showing your login credentials
In some versions of bash the ending EOF needs to be at the beginning of the line to work.

Btw, if you "source" a script running it like . .script, than an exit in that script will log you out.

Difference between database features - SQL Server 2008 R2 navtive vs SQL Server 2012 with SQL Server 2008 compatibility set?

I am investigating the impact of upgrading from SQL Server 2008 R2 to SQL Server 2012. To reduce the impact of the upgrade, I am planning to restore / create our application database onto SQL Server 2012 with compatibility level 100 (SQL Server 2008 and
SQL Server 2008 R2).
Are there any differences in feature support for database running in native mode on SQL Server 2008 R2 vs a database installed on SQL Server 2012 with compatibility level 100 set?

Are there any differences in feature support for database running in native mode on SQL Server 2008 R2 vs a database installed on SQL Server 2012 with compatibility level 100 set?
Yes there can be difference and impact there are few features deprecated in SQL Server 2012 you must be aware about that. Please see
Deprecated Database Features in SQL Server 2012
Deprecated SQL Server features in SQL Server 2012
After you migrate database to 2012 please don't move ahead with production unless you have tested your application to new created database

SQL Server 2012 with SP1 on Windows 8.1 Pro

Can I install "out-of-the-box" SQL Server 2012 with Service Pack 1 Enterprise Edition or SQL Server 2012 Developer Edition on my Windows 8.1 VM?
Thanks.

Hello,
SQL Server 2012 SP1 is fully supported by Windows 8.1, and there is no need to install any SQL update for the installation.
Enterprise Edition is not supported on client operating systems like Windows 8.1 but setup won’t prevent you from installing.
Developer Edition is fully supported on client operating systems.
Hope this helps.

How to enable high availability on SQL Server 2005 with Windows Server 2008 Enterprise R2

Dear Folks,
I would like to ask you about this thing. I'm working for IT department for bank in Myanmar. Our bank have up to 96 branches across all of Myanmar including H.O. We are using Microsoft SQL Server 2005 with Windows Server 2008 for our banking
information system. My main problem is having to backup and restore the database backup files every time the servers in branches goes down for whatever reasons. I want to deploy this feature of high availability and failover cluster using Windows Server 2008
and SQL Server 2005. Our branches have 2 Servers. One is for Primary and other is for Backup. What I want to do is that, I want to change Backup Server to Primary Server whenever the Primary Server goes down for whatever reasons. All the working data and databases
from Primary will immediately replicated into Backup Server along with all the IP information of Primary Server. Please give me step by step guide for this process.

Try below
http://blogs.msdn.com/b/cindygross/archive/2009/10/23/checklist-for-installing-sql-server-2005-as-a-clustered-instance.aspx
I will recommend you to upgrade SQL server to newer version for support as well as flexibility.

SQL Reporting Services with Java EE

I have developed a Java application for calling the SQL Reports. A couple of reports are made in the server. This SQL Reporting server is deployed and the client is made in the java using Werb services. Whenever a search is done from the Java application, reports are displayed on the JSP page using the web service methods. But the problem is the entire report is displayed. Is there any way to display the report based on the particular item search. Suppose, if search is made on "Australia" in the coulumn Country, the report should contain only Australian related data. Currently the search is based on the report name itself.

This looks hopeful.I have already developed a java EE for calling reports with the help of ---"MSDN Virtual Lab: Implementing SQL Server Reporting Services with a Java Enterprise Edition (EE) Application (ID:1032315323)". Now I need to find out the parametrized reports(passing parameters to the report calls and more customization using java). In .NET, reportviewer controller is available for this purpose. I want to achieve the same type of thing using java.The protocol of controlling the Report Server is a feature of the Report Server.
To control it you learn the protocol. To use it you program it in java.
The first has nothing to do with java. The second obviously does.

Trying to install features for PowerPivot and Reporting Services from SQL Server 2012 with SP2, but no access to key?

Hi,
I had installed SQL Server 2012 PowerPivot on WFE and App Server. This is test farm with 1 WFE and 1 APP and 1 SQL Server.
However, we had a heap of issues with Windows Claims Authentication and PowerPivot - issues were raised with "unable to make a connection to EntityDataSource" . Now we uninstalled the PowerPivot and Reporting Services features and wanted to install
with the SQL Server 2012 with SP2. Originally SP2 was installed seperately and we had read there had been issues.
Anyway on trying to install the features again using the SQL Server 2012 with SP2 iso I get
Could not open key UNKNOWN\Components
I don't want to start deleting or changing permissions as quite dodgey. What is this key for anyway and how do I resolve my issue.
Thanks.
John.

Hi John,
Did you meet the error message during the process of configuring the PowerPivot for SharePoint?
If yes, I suppose that the existing features or components have not been uninstalled completely.
I recommend to delete the two keys left when uninstalling the PowerPivot and please make a copy of the registry keys before you delete the two keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\15.0\WSS\ServiceProxies\Microsoft.AnalysisServices.Sharepoint.Integration.MidTierServiceProxy
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\15.0\WSS\ServiceProxies\Microsoft.AnalysisServices.Sharepoint.Integration.MidTierServicea
Please check the steps in the link below to see if there anything wrong when you uninstalling the PowerPivot and then re-install it to see how it works:

PL/SQL Callback notification with aq$_jms_text_message

Hi,
i want to set up a notfication for a pl/sql callback procedure. The message in my queue is enqueued via propagation from another instance. This is my setup (using oracle 10.2.0.3):
-------- the queue (multiconsumer): --------------
begin
dbms_aqadm.create_queue_table(queue_table => 'zmon_evt_in_qtable',queue_payload_type => 'sys.aq$_jms_text_message', multiple_consumers => true);
dbms_aqadm.create_queue(queue_name => 'zmon_evt_in_queue',queue_table => 'zmon_evt_in_qtable' );
dbms_aqadm.start_queue( queue_name =>'zmon_evt_in_queue' );
end;
-------- the callback-procedure (simply inserting an entry in a table called 'test'): --------------
create or replace procedure evt_in_callback(
context IN RAW,
reginfo IN SYS.AQ$_REG_INFO,
descr IN SYS.AQ$_DESCRIPTOR,
payload IN VARCHAR2,
payloadl IN NUMBER) is
begin
insert into test(textfeld) values ('RECEIVED!');
commit;
end evt_in_callback;
-------- the subscriber: --------------
begin
dbms_aqadm.add_subscriber(queue_name => 'zmon.zmon_evt_in_queue',
subscriber => sys.aq$_agent('zmon_evt_in_subscriber',null,null));
end;
-------- the notification: --------------
declare
reginfo sys.aq$_reg_info;
reg_list sys.aq$_reg_info_list;
begin
reginfo := sys.aq$_reg_info(name => 'zmon.zmon_evt_in_queue:zmon_evt_in_subscriber',
namespace => DBMS_AQ.NAMESPACE_AQ,
callback => 'plsql://zmon.evt_in_callback',
context => HEXTORAW('FF')
reg_list := sys.aq$_reg_info_list(reginfo);
DBMS_AQ.REGISTER(reg_list => reg_list,
reg_count => 1);
end;
The callback-procedure is not fired on arrival of a message in the queue. But i can see the the appropriate notfication-entry in sys.reg$.
Any suggestions why this doesn't work ?
BTW: can anybody tell me the meaning of the context-Parameter in the aq$_reg_info-Type ? Everybody uses HEXTORAW('FF'), but I don't understand what that means...
Jens
Edited by: dschenzl on Jun 4, 2009 11:13 AM

Finally, it's done.
The subscriber used in the propagation has to be the notification-subscriber (zmon_evt_in_subscriber). I used another subscriber, which was not registered for notification.
I found the solution in this thread: Callback trouble from mesage via propagated message.
Two days filled up with frustrating work - man, how i hate that...

Construct a Sql block using With Clause to improve the performance

I have got four diff parametrized cursor in my Pl/Sql Procedure. As the performance of the Procedure is very pathetic,so i have been asked to tune the Select statements used in those cursors.
So I am trying to use the With Clause in order to club all those four Select Statements.
I would appreciate if anybody can help me to construct the Sql Block using With Clause.
My DB version is..

Not tested. Some thing like below. i just made the queries as tables and given name as a,b,c and substituted columns for the parameters used in the 2nd cursor and third cursor. Try like this.
CURSOR all_iss (
b_batch_end_date IN TIMESTAMP,
IS
select a.*,b.*,c.* from
( SELECT isb.*
FROM IMPLMN_STEP_BREKPN isb
, ISSUE iss
WHERE isb.issue_id = iss.issue_id
AND iss.issue_status_id = 50738
AND ewo_no IN
(SELECT TO_CHAR(wo_no)
FROM MGO_PLANT_AUDIT
WHERE dml_status = 'U' OR dml_status = 'I')
UNION ALL
SELECT isb.*
FROM IMPLMN_STEP_BREKPN isb
, ISSUE iss
WHERE isb.issue_id = iss.issue_id
AND iss.issue_status_id = 50738
AND CAST (isb.last_updt_timstm AS TIMESTAMP) >=
b_batch_end_date) a,
( SELECT DISTINCT wo_no ,
plant_code
FROM MGO_PLANT
WHERE TO_CHAR(wo_no) = p_ewo_no) b,
( SELECT *
FROM IMPLMN_STEP_BREKPN
WHERE issue_id = p_issue_id
AND ewo_no = p_ewo_no
plt_faclty_id IS NULL) c
where b.wo_no = c.ewo_no and
c.issue_id = a.issue_id ;
