Sir,
The zip file doesn’t contain the table creation scripts that you have used in demos. Kindly provide that also.
Hi
Mhmm… almost every script creates the tables it needs… With which demo do you have problems?
Cheers,
Chris
Sir,
I am talking about t1,t2,… tables.I couldn’t find them.
Many thanks
Hi
IIRC the only scripts that do not create t1, t2, … are the ones of chapter 10. In fact, those scripts call the script create_tx.sql for that purpose. If they are not automatically created when you run a script it probably means that your current directory is not the onewhere the scripts are stored.
HTH
Chris
Sir,
Thanks for the reply.I found them in the folders.
BTW,when are you planning to write a book on instance tuning? Or it would have been wonderfull if the TOP had a section for instance tuning also.That certainly would have completed the meaning of TOP.
Hi
> BTW,when are you planning to write a book on instance tuning?
I do not plan to write another book. The only thing I can think of, is to provide a second edition of TOP….
> Or it would have been wonderfull if the TOP had a section for instance tuning also.
I basically agree with you. But, since time is restricted, I had to make a choice. And, honestly, instance tuning is irrelevant in most situations with the current releases. In fact, most of the time I see customers struggling with either poor hardware performance or applications-related issues.
Cheers,
Chris
Sir,
You are absolutely correct. Oracle has automated so many things like ASMM etc that there is no need to worry about sizing memory structures.But at times we do get contentions in shared memory,lock issues,Buffer cache contentions etc.Since you got an amazing talent to write and explain things,it would be a great help to the oracle community if you could enlighten the subject.
