Sqlplus as sysdba very slow

Join the world’s largest interactive community dedicated to Oracle technologies.

How should I know what is happening within, whether the sqlplus has hanged upor it it is going to return with the total number of records. I have other tables in which I have 2 to 10 million records. I need a solution becasue this is taking toomuch of effort and time. I know it is going to take time to return the total number, but what I want is a routine which can tell me how many records have been counted at a particular given point of time, or whether the count has stopped inbetween due to some reason.

How should I do it, is there a script which I can write, to do this. Please help, I need it desperately. Well, sqlplus isn't hanging, its just waiting for the answer. I do not see why you would need to count the totally number of records would need to know more about your processing to suggest a way to AVOID having to do that but you can monitor the progress.

You can simply open another session, use my showsql. You can also catch regular content via Connor's blog and Chris's blog.

Question and Answer. Latest Followup. You Asked Tom These days Iam facing a huge problem which is wasting a lot of mytime. Presumably a materialised view could achieve the same thing. If you don't need an exact number, then consider analyzing the table using "estimate".

Hi: Connor's solution a row level trigger will add some processing to the database, and that may not be something the users can afford.

It might be better to use table growth to estimate the number of rows after you have a million, that should be pretty easy. Anyway, the hard part of this question is what can possibly be the difference between 1 million rows and 1. Anyway, Tom's suggestion is interesting, another table that I did not know existed, and a neat script to use it.I have a situation where when I login as a user to my DBvia sqlplus no service name it takes about 20 secs to connect. Yet when I login as a user with DBA privs it logs in immediately.

Is there something I can do to trace what is happneing behind scences to determine what the login delay may be. But I did this.

I created an externally authenticated user in database. And can login without password with below syntax. Previously I used to login using below syntax.

I just create a user and tried to log in but it gives the following error, why? All rights reserved. From metalink: Note Im trying to install SQLT. We have two database instances on the same server. One was left at 9. Connecting externally to the We are using "tnsnames". I have a query which takes 5 minutes when run through the java app which uses hibernate. I don't know how to get the explain plan when it's running through the app or why it should be any different anyway as the query is identical.

Sometimes the GUI even hanging without displaying results. Does Partitioned Tables feature works for better performance? May be am wrong to ask this question but i need to login and check the requirement.

Is there any other anyway to login without sqlplus utility? I see we are unable to login to database using global database.

Step-6 Login through web browser. Every thing is working but when we click on button in login form at that time parameter. I have installed Oracle in workgroup, while i workgroup it is working fine. But latter I have change the server from workgroup to domain. At that time Oracle was not workingnot able to connect. After that I change the Domain to workgroup again.

And same problem exist. But I found that lsnrctl is working fine. I have installed executable only database option only when i have installed oracle11 that time it is not asking any option for password. So is there any option to login in this type of condition?

It is therefore recommended, where possible to get 2 hanganalyze and 2 systemstate dumps in order to determine whether processes are moving at all or whether they are "frozen". Therefore without these fixes in place it highly unadvisable to use these level For information on these patches see: Document It does this every 3 seconds for local hanganalyze information and every 10 seconds for global RAC hanganalyze information.

This information can provide a quick view of hang chains occurring at the time of a hang being experienced. More information: Document Collecting information about the general performance of the database in the build up to, during and after the problem is of primary importance since these snapshots can help to determine the nature of the load on the database at these times and can provide vital diagnostic information.

This may prove invaluable in identifying the area of the problem and ultimately resolving the issue. To do this, please take and upload snapshot reports of database performance AWR or statspack reports immediately before, during and after the hang.

Please refer to the following article for details of what to collect: Document See the following note on My Oracle Support: Document In these cases, the following methods may be used to gather diagnostics: As an alternative to the manual collection method notes above, it is also possible to use the HANGFG script as described in the following note to collect the information: Document LTOM proactively provides real-time automatic problem detection and data collection.

For more information see: Document It is recommended that all users install and run OSWbb since it is invaluable for looking at issues on the OS and has very little overhead. It can also be extremely useful for looking at OS performance degradation that may be seen when a hang situation occurs. It analyzes current performance when database is hanging or running slow and reports sources of severe contention.

Bit of an odd question, to be honest. In any event, just to be pedantic, sqlplus nor any other client application actually reads the tnsnames file. It simply passes the request to the Oracle net layer, which takes care of all routing issues, including resolving a net service name tnsnames entry into an actual ip address and listener port number.

Looks like an SGA memory issue. You should really only set these when directed to do so by Oracle Support.Sound familiar? If it does, you are not alone. What should you do next? In this article, you will learn some techniques for troubleshooting Oracle Database performance issues.

To use the scripts in this article, you need to create some tables in a test schema and access some dynamic performance views. The script for setting up the example tables is available in the sidebar. Before you start troubleshooting why a database is slow, you have to first understand that the database itself is never slow or fast—it has a constant speed.

The sessions connected to the database, however, slow down when they hit a bump in the road. To resolve a session performance issue, you need to identify the bump and remove it. The first step to resolving a session performance issue is to ascertain what that database session is doing now. An Oracle Database session is always in one of three states:. If a session is waiting for some resource, such as a block or a lock, it has stopped processing. Until it gets that resource, the session will continue to wait.

When it gets that resource, it does some processing and then moves on to the next resource it needs, waits for that to be available, and starts processing.

If it waits for resources often, the session will appear slow. Everything you need for your analysis is in this view.

To follow along, first set up the previously mentioned tables as described in the online version of this article. Then connect as user ARUP from two different sessions.

From the first session, issue the following SQL statement:. By not committing, you will force the session to get and hold a lock on the first row of the T1 table. Now go to the second session and issue the following SQL statement:. This statement will hang. The answer is simple: the first session holds a lock on the row, which causes the second session to hang and the user to complain that the session is slow. Study the output carefully.

Session in the SID column indicates that it is waiting for something—and therefore not working. That should be your first clue that the session is experiencing one of those performance bumps in the road. The EVENT column not only shows an event a session is waiting for currently, but also shows an event a session has waited for earlier.

The session is waiting because it wants to lock one or more rows, but another session has already placed locks on the row or rows. Unless that other session commits or rolls back its transaction, session will not get the lock it needs and will have no choice but to wait. There is one very important lesson in these results: you cannot look at the EVENT column alone to find out what the session is waiting for. After you determine that a session is waiting for something, the next thing you need to find out is how long the session has been waiting.

A very long wait usually indicates some sort of bottleneck. Where can you get information on the length of the waiting period? Getting the amount of time a session has been waiting makes sense for sessions that are waiting right nowbut what about the sessions that are working now? Recall that the EVENT column shows not only the event a session is experiencing now but also the last wait event the session has experienced. It clearly shows the state of the sessions: whether they are working or waiting; if they are working, what they were waiting for earlier and for how long; and if they are waiting, what for and for how long.

Recall from the previous section that an Oracle Database session can be in one of the three states: working, waiting for a resource, or waiting for work.Need support for your remote team? Check out our new promo! IT issues often require a personalized solution.
