Logging SQL for automatic index generation or performance Analysation ?
Hi, I would like to know where the best place would be to hook into ojb a class which logs all sql statements sent to the DB. My idea is to analyze the from and where clause and log into a database table the actual statements used in a live system. I then would like to write a tool which analyzes this table and suggests the best indices to create on the database. To make sure I really catch all statements I would like to directly hook into ojb. Also, this could then easily be re-used. We thought about a trace but the amount of data just seems to big. Any ideas / suggestions ? Thanks, Stefan Schlösser - I N T E R M E D I A T E GmbH Co.

Re: [OTM] can not delete from dependent collection
Oleg Nitz on at ukr.net writes: I am trying to support long transactions in OTM. I didn't keep them in mind before, but now I realized that original Raghu design contains even a special package - swizzling - which is a way of doing long transactions. I.e. otmconn.makePersisntent() should work similar to broker.store(): if exists then update, if doesn't exist then create. Of course, automatic update of all changes and update via makePersisntent() are mutually exclusive: only the object which was read inside transaction (say, via getObjectByIdentity()) *is in transaction*. The object passed to makePersisntent() is not included in the transaction (unless it is new), it is just swizzled with transactional object (its fields values are copied to the transactional object). Just curious: What does this mean for my latest issue report? Is it an issue in OJB OTM or do I have to modify my code partly? And did you come across the swizzle thing before or after patching the other issues :) Not that I need it immediately, I have some else work to do on my project, but of course updating objects is somewhat important to me :) Joerg - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

However, if the operation is performed via tomcat, the db does not get updated. There are no errors reported. If I enable the debugger and put a breakpoint, then the db gets updated properly. It seems as if the application is too fast for the cache to update the database and garbage collection kicks in and cleans the update object. I am using ObjectCacheDefaultImpl.

Re: Extent problem with ODMG
I'm still having this problem, so I'm going to try again. Using ODMG, RC5, Oracle 9i. Summary: - Class A has a 1-to-1 relationship 'abs' to an abstract superclass S - Class S has concrete subclasses B and C - Classes B and C share a common relationship 'com' to another class D; this relationship is defined in the superclass S - Class D has a property 'p' - A, B, C, and D map to distinct tables I am trying to retrieve all A's which have a given value for 'p' in the D associated with the related B or C (whichever one it is). So: select x from A where A.abs.com.p = ? A.abs has type S, the abstract superclass; A.abs.com has type D. This means that the query needs to generate some sort of interesting join to check for both possible paths to D (via B or C), knowing that either B or C will have exactly one row satisfying the join condition(s). In pseudocode: select x from A where if A.abs instanceof B then ((B) A.abs).com.p = ? else if A.abs instanceof C then ((C) A.abs).com.p = ? Should I expect this to work? The SQL query which is being generated is not only incorrect but invalid: OJB does not rewrite 'p', and in fact does not even mention D at all. I assume this has to do with the fact that the repository doesn't record the presence of the relationship 'com' in the abstract superclass, but only in the subclasses. Queries starting from B or C and following the 'com' relationship work fine. Am I out of luck, or is there some way I can get a working query out of this? thanks for any insights, Steve Clark Technology Applications Team Natural Resources Research Center/USGS [EMAIL PROTECTED] (970)226-9291 PS: Original message below.

Re: ODMG UPDATE TOO FAST: DB not updated from jboss(daemon) and tomcat
Hi Sukesh, If you can see by debugging (or easier by using the P6Spy jdbc tracer) that ojb executes the correct insert or update, then the problem can not be cause dby cache / gc interaction. The only explanation i have for such a behaviour is that a database commit is not done after executing your statement. Why could this happen? JBOSS is a fullfledged J2EE container with JTA transaction manager and Tomcat isn't. SO under commit you must use explicit commits. Please check your OJB.properties settings that define the transactional behaviour. cheeers, Thomas Sukesh Garg wrote: My application accesses OJB via the JBOSS startup daemons and TOMCAT. The database gets updated correctly when the operation is performed via the JBOSS daemon. However, if the operation is performed via tomcat, the db does not get updated. There are no errors reported. If I enable the debugger and put a breakpoint, then the db gets updated properly. It seems as if the application is too fast for the cache to update the database and garbage collection kicks in and cleans the update object. I am using ObjectCacheDefaultImpl. I tried explicitly marking the object dirty but no success. Would really appreciate any help. thx, Sukesh - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Logging SQL for automatic index generation or performance Analysation ?
Hi Charles, thanks for this, this tool is great - I already got 1 half of what I need. Took me some 30 min. to integrate it in our application ! Thanks. Stefan Charles Anthony wrote: Hi, I'm not sure if you are aware, but there is already a tool to do this, based on the p6spy jdbc driver. It's available under the Apache license too. I believe the only thing it doesn't do is the analysis of the data to suggest indices. http://www.irongrid.com/catalog/product_info.php?products_id=32 I've only glanced at the tool, not used it. Even if that tool is not what you want, it's probably better to extend the p6spy driver to do what you want - as it would be applicable across all environments that use jdbc Cheers, Charles. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: 03 March 2004 08:32 To: [EMAIL PROTECTED] Subject: Logging SQL for automatic index generation or performance Analysation ? Hi, I would like to know where the best place would be to hook into ojb a class which logs all sql statements sent to the DB. My idea is to analyze the from and where clause and log into a database table the actual statements used in a live system. I then would like to write a tool which analyzes this table and suggests the best indices to create on the database. To make sure I really catch all statements I would like to directly hook into ojb. Also, this could then easily be re-used. We thought about a trace but the amount of data just seems to big.
