Hi Oracle gurus,

This is an interview question.

Developer is doing a transaction and it is failing due to insufficient space in the undo tablespace.
Could you please provide the solution for this issue other than increasing the undo tablespace.

Environment is prod.

Regards,
Balaji

After more than 12 years as a DBA you still don't know how to manage undo space?
Why are you still trying to get such a job?

This issue is not about managing undo tablespace.If you had read my question clearly, you wouldn't have asked me such question.

That's none of your business.

If you don't know the answer for this question just keep quiet, let others answer.

Balaji

Explain your question then.
For myself, I've always been able to manage such errors and problems.

Your putative interviewer may be less interested in whether you have memorized answers than in whether you have any problem solving skills. For example, you could begin by asking "What is the error? Is it, for example, an ora-30036 ?" If so:
C:\Users\john>
C:\Users\john>oerr ora 30036
30036, 00000, "unable to extend segment by %s in undo tablespace '%s'"
// *Cause:   the specified undo tablespace has no more space available.
// *Action:  Add more space to the undo tablespace before retrying
//           the operation. An alternative is to wait until active
//           transactions to commit.

C:\Users\john>

I have already explained my question in this thread.

I didn't ask whether you managed such errors or not. I asked solution to my question.

No, you didn't.
This is one the problems, you don't understand your question.
The proof: your question is "transaction [...] is failing due to insufficient space in the undo tablespace"
How do you know the transaction is failing? How do you know it is for this reason? How is this not about managing undo space? Do you understand my question?

As I already told you many times in these years and John reminded in this topic: "Your putative interviewer may be less interested in whether you have memorized answers than in whether you have any problem solving skills".

Anyway, it is just a wasting of time to try to explain you something because during these last 13 years:
1/ You showed you couldn't read the documentation
2/ You showed you couldn't search in the documentation
3/ You showed you couldn't search in the web
4/ You showed you couldn't understand what we explained
5/ You showed you couldn't even memorize what we said as you often repeated the same questions over the years

In the end, you showed you didn't want to help others when you said you had the answer as you refused to post it.

You're falling again in the bad behavior you promised you won't.

Did it not occur to you to ask how it failed, if there were no errors?
Did it not occur to you to ask how it is known - with no errors - that the 'no error' failure was due to insufficient undo space?

How would you imagine that the solution for 'insufficient undo space' is different for prod that "not prod"? In other words, how is knowing the environement is "prod" relevant to the solution?
