Usage Tracking - Cant perform insert operation inside a READ ONLY trans

Hello,
I have been experiencing the following error message when trying to install a row in our s_nq_acct table for USAGE TRACKING:
[nQSError: 16001] ODBC error state: S1000 code: 1456 message: [Oracle][ODBC][Ora]ORA-01456: may not perform insert/delete/update operation inside a READ ONLY transaction.
- I am able to manually insert rows via SQL*Plus whilst logged on as the same user as the Connection Pool
- The Read Only option is not ticked for the ODBC
Can anyone please help me with this?
Thanks,
Rhys

Hi rnm1978,
You were right!
I was being a bit retarded and had to simply switch the call interface on the connection pool to use the OCI and ensure the dta source name was that of the TNS names entry and not the system DSN.

Cannot perform dml operation inside a query

I have created a function which does some dml opration.
when I use it in a through a transformation operator, and execute the map,
it throws the following error:
cannot perform dml operation inside a query
how to handle this?

Hi,
if you want to execute the dml within a mapping, use the pre or post mapping procress operator. Or use a sql*plus activity in the process flow.

Problem Description
When running a RAM build you get the following error as seen in the RAM build
log file:
14:52:50 2> Updating warehouse tables with build information...
Process Terminated In Error:
[Oracle][ODBC][Ora]ORA-01456: may not perform insert/delete/update operation inside a READ ONLY transaction
(SIGENG02) ([Oracle][ODBC][Ora]ORA-01456: may not perform insert/delete/update operation inside a READ ONLY transaction
) Please contact the administrator of your Oracle Express Server application.
Solution Description
Here are the following suggestions to try out:
1. You may want to use oci instead of odbc for your RAM build, provided you
are running an Oracle database. This is setup through the RAA (relational access
administrator) maintenance procedure.
Also make sure your tnsnames.ora file is setup correctly in either net80/admin
or network/admin directory, to point to the correct instance of Oracle.
2. Commit or rollback the current transaction, then retry running your
RAM build. Seems like one or more of your lookup or fact tables have a
read-only lock on them. This occurs if you modify or add some records to your
lookup or fact tables but forget to issue a commit or rollback. You need to do
this through SQL+.
3. You may need to check what permissions has been given to the relational user.
The error could be a permissions issue.
You must give 'connect' permission or roll to the RAM/relational user. You may
also try giving 'dba' and 'resource' priviliges/roll to this user as a test. Inorder to
keep it simple, make sure all your lookup, fact and wh_ tables are created on
a single new tablespace. Create a new user with the above privileges as the
owner of the tablespace, as well as the owner of the lookup, fact and wh_
tables, inorder to see if this is a permissions issue.
In this particular case, the problem was resolved by using oci instead of odbc,
as explained in suggestion# 1.

Error with OBIEE Usage Tracking

Hi,
I have set up Usage Tracking in Oracle BI Enterprise Edition with the Direct Insert Option. I have created the S_NQ_ACCT table in an Oracle schema that is referenced as a connection pool in the Oracle BI Repository physical layer. When I run my requests from Oracle BI Answers and check my server logs (NQServer.log), I get the following message:
[59048] Usage Tracking encountered an insert statement execution error. This error has occurred 9 times and resulted in the loss of 9 insert statements since this message was last logged.

Does anyone know how to fix this problem?

Thanks for the response.
You're right. The response seems to imply that the account does not have the authorization. However, the account I am using to access the database from OBIEE Repository owns the schema where the S_NQ_ACCT table is stored. So I am puzzled as to why this response is generated.

Usage tracking in Siebel Analytics

Hi All,
We are using Sibel analytics for the reporting on non-siebel database. We tried to implement the Usage tracking for that.
We have created the table "S_NQ_ACCT" on our dabase and all the settings are done in NQS file.
But when any report is ran, the usage statistics are not getting inserted in to the table S_NQ_ACCT.
Thanks all.

Trouble shoot Usage Tracking

I configured Usage tracking but for some reason S_NQ_Acct table is not populating rows. I checked the error log and I see there has been some problem with the usage tracking. I used the 10.1.3.4 usage tracking rpd and did update the connection pools to point to the right database.
The rpd metadata columns and the tables created under the schema are consistent. I do not see any errors under Usage tracking canned reports or the columns. All i see is No results because S_NQ_ACCT table is always empty, even though I ran some reports.
Here is my usage tracking settings under nqsconfig.ini file
ENABLE = YES;
DIRECT_INSERT = YES;
PHYSICAL_TABLE_NAME = "OBI Usage Tracking"."Catalog"."dbo"."S_NQ_ACCT" ;
CONNECTION_POOL = "OBI Usage Tracking"."Usage Tracking Writer Connection Pool" ;
BUFFER_SIZE = 10 MB ;
BUFFER_TIME_LIMIT_SECONDS = 5 ;
NUM_INSERT_THREADS = 5 ;
MAX_INSERTS_PER_TRANSACTION = 1 ;
My NqServer log details:

I tried to debug what that error is but i was not successfull in doing so. One thing that i wanted to mention here is, when creating the NQ_LOGIN_GROUP view, I edited th default script for creating the column LOGIN to USER_NAME as LOGIN is a key word in ORACLE database. I dont think that is causing the issue here, as I renamed the rpd Physical column of the table as well. That was the only change i made and rest of them are default settings.
Any suggestions here....
Thanks
Prash

A lot of things smell fishy in your post. For a start your BI Server log says "Metadata Database Type: Oracle8.1" but then it says you are using "Client Driver Version 10.02.0001". Which database version are you running? If you are running 10g then make sure you set the correct database type in the Physical layer. If you are using Oracle then you should be using Oracle native drviers in your connection pool (OCI) however the PHYSICAL_TABLE_NAME definition has the "dbo" which seems to suggest you are using ODBC. Also the error you are gettign seems to suggest you are using ODBC. The insert the BI Server sends looks like this:
INSERT INTO S_NQ_ACCT (USER_NAME, REPOSITORY_NAME, SUBJECT_AREA_NAME, NODE_ID, START_TS, START_DT, START_HOUR_MIN, END_TS, END_DT, END_HOUR_MIN, QUERY_TEXT, SUCCESS_FLG, ROW_COUNT, TOTAL_TIME_SEC, COMPILE_TIME_SEC, NUM_DB_QUERY, CUM_DB_TIME_SEC, CUM_NUM_DB_ROW, CACHE_IND_FLG, QUERY_SRC_CD, SAW_SRC_PATH, SAW_DASHBOARD, SAW_DASHBOARD_PG, PRESENTATION_NAME, RUNAS_USER_NAME, NUM_CACHE_INSERTED, NUM_CACHE_HITS)
So try that manually to see if it works but it seems you need to to some RPD config changes first as it all looks too fishy to me.

Usage Tracking for BI Server Hosting Multiple Repositories

Hi all,
I've got my BI Server hosting two repositories:
[ REPOSITORY ]
DemoApp1 = DemoApp1.rpd, DEFAULT;
DemoApp2 = DemoApp2.rpd;
And started two Presentation Services connecting to these two repositories respectively, and two web front-ends at /analytics and /analytics2 to display the two different catalogs.
Next, I enabled usage tracking with direct insert to the following physical table:
PHYSICAL_TABLE_NAME = "OBIEEREP".""."OBIEEREP"."S_NQ_ACCT" ;
CONNECTION_POOL = "OBIEEREP"."Connection Pool" ;
Both repositories has the above physical table and connection pool defined. In DemoApp1.rpd, "OBIEEREP"."Connection Pool" points to a database OBIEEDB1, and in DemoApp2.rpd, it points to a database OBIEEDB2.
But then the problem occurs. All usage tracking data are inserted to OBIEEDB1 only, no matter which web front-end they are from. I tried removing the "DEFAULT" from NQSConfig.ini, but this doesn't help.
Is there any way to configure BI Server to insert usage tracking data from /analytics to OBIEEDB1, and those from /analytics2 to OBIEEDB2?
Thanks very much!!!
Edited by: Kaphenda on Jan 18, 2010 2:34 PM

HI Kaphenda,
That's probably just a side-effect of having two repositories. Keep in mind that having multiple repositories and multiple presentation servers is not support by Oracle, so they were not on the hook to modify the Usage Tracking algorithm to write to two different databases. It seems to me like they either didn't anticipate this scenario, or they didn't want to program for this scenario.
I don't think you have too many options in terms of making OBIEE insert the traffic logs into the appropriate database. However, once the data has been inserted, you can do just about anything you want to it in terms of ETL, triggers, materialized views, etc.
Here's what I would recommend:
1) Have the OBIEE usage tracking information logged into a neutral schema.
2) Write a materialized view in database 1: CREATE MATERIALIZED VIEW S_NQ_ACCT AS SELECT * from S_NQ_ACCT@NEUTRAL_SERVER WHERE REPOSITORY_NAME = 'DemoApp1'
3) Write a materialized view in database 2: CREATE MATERIALIZED VIEW S_NQ_ACCT AS SELECT * from S_NQ_ACCT@NEUTRAL_SERVER WHERE REPOSITORY_NAME = 'DemoApp2'
You can specify the refresh frequency of these materialized views to be as frequent as you want. The great thing about this strategy is that you get the best of all worlds. Each database has the traffic information broken down by their personal RPD. But the neutral schema can provide Global reporting across both repositories which can be very valuable itself.
Good luck and if you found this post useful, please award points!
Best regards,
-Joe

Create tables insert something inside and then connect my application to db

thank you to be patient with me. ok since the beginning I think I have learned a lot with the people responses. so my database is mounted now. I used the cmd.exe command line. i have create an instance, a service, and the database. Now, I need to do two things:create tables inside of my database and insert something inside but I only have the sql script (I will add it at the end of the thread).it is just a part of my huge script.. but this cript can not be open with the command line. So I want to know if you could help me change some stuff inside in the aim to run this script with the command line.that's the first point
secondly, I have an application named lifetrack. i want to connect this application with my database. so how can I change my settings file to be able to do that?(I will add the settings file I have at the end.It is the one I use for sql server). thanks a lot.I'm a french student so I try my best to answer you in a good english. and believe me if I have the exact way to create table,insert something inside like indicate in the part of my script and connect an application to the database you will never see my thread again. thank you

Cannot perform scripting operations on lists

Hi,
I'm having trouble performing scripting operations on lists, the only variables I can retrieve from lists are the values @HasLeadSelection, @LeadSelectedIndex and @RowCount. I cannot perform any methods on lists, I have gone through the Complete Help document and have also tried to use Resolve to attempt to access list rows but that doesn't seem to working either. Any help would be greatly appreciated!
Thanks
Alexander Ludwig

Hi Alessandro & Alexander,
I just tried it and yes we can change the colour trough scripting as well.
Something like below in the Calculation Rule of the property Background Colour would do the job.
result = 'STANDARD' // This is a fallback value in case the if condition below is not satisfied.
if( $currentrow.xxx == 'xx' ) // Here xxx should be the element within the table
result = 'BADVALUE_DARK' // This is one of the value from above screenshot.
end
Check this other thread for more details:http://scn.sap.com/thread/3528872
And yeah the code completion is having serious issues. It shows the attributes which do not belong under is sometimes.
Binding to another attribute and setting it trough ABSL might decrease the performance as there would be a roundtrip required in this case to change the value if this field is not shown on UI and is only used to decide the colour.

Vinod

Usage Tracking performance impact

Hi all,
I just started to implement the OBIEE usage tracking functionalities.
Anyone implemented it and call share some experience on the performance impact with/without usage tracking enabled??
Thanks
BCHK

If you use direct_insert option impact will be minimized. In general usage tracking captures report run activity and logs into table, so there is overhead on the system to insert to table or write to file. trade off is the information you get with usage tracking..
hope this helps..

Yes - and the exception is telling you EXACTLY what the problem is. You have a query
IF INSERT_BATCH(99,varSTMT) > 0 THEN
And you are performing a DML operation inside that query:
INSERT INTO BATCH_STATEMENT(QUEUE_ID,TABLE_ID,STATEMENT,QUEUE_SEQUENCE_ID)
    VALUES (numQUEUE_ID,numTABLE_ID,varSQL_STATEMENT,1);
Like the exception says: you can't do that.
You need to call the function using PL/SQL and capture the return value into a variable. Then test that variable:
myVar := INSERT_BATCH(99,varSTMT);
if myVar > 0 THEN

Degrading performance when running consecutive insert operations

Hi,
I'm using DB-XML (2.5.16) as a backend storage for a web application that works on top of a TBX (TermBase eXchange) document. The application is using the Python bindings and development is being done on GNU/Linux with Python 2.6.
The document is stored in a node-storage container, autoindexing is off at the time of container creation and transactions are enabled.
After a set of indexes are set, queries work quite fast.
On the other hand, when users input new data (terms) or perform edits on existing data, insert and replace operations have instant effect.
The application has also a feature to insert lots of new terms in a single click, resulting in a new insert operation for each term. If the amount of terms to be inserted is relatively small (let's say ~10), the operation is quickly performed and the user receives a response almost instantly.
Anyway, the problem arises when there are lots of new terms to be inserted. It starts working fast but performance quickly starts to degrade badly, needing more long seconds for each insert operation. Python's CPU-usage seems to go up to 100% when doing the actual insert, too.
I understand this is not the best-working scenario for DB-XML (a single large document), but I don't think this performance is normal or acceptable.
I have tried increasing Berkeley DB's cache size to 64MB with no success.
Any hints about what should I be looking at? any more recommendations?
These are the defined indexes:

As you both have mentioned I have tried increasing the cache size to 512MB or even to 1GB (I have recreated the entire DBs after setting cache sizes), but I don't see any significative improvements.
I have also tried to tune my insert queries, and now I think they're in better shape than before. I would say the initial inserts feel slightly faster, but this only happens when the DB is empty (just bootstrapped). Then, once the DB has some term entries and grows in size, it starts to degrade and inserting becomes expensive in order of magnitudes.
Each insert operation is performed in a separate transaction. And yes, I'm using transactions all over the application.
Vyacheslav, I'll send you a couple of containers along with insert queries created by the application so you can play with.

"cannot perform a DML operation inside a query" error when using table func

hello please help me
i created follow table function when i use it by "select * from table(customerRequest_list);"
command i receive this error "cannot perform a DML operation inside a query"
can you solve this problem?

Now what exactly would be the point of putting a SELECT FOR UPDATE in an autonomous transaction?
I think OP should start by considering why he has a function with an undesirable side effect in the first place.
