Oracle forms opening slowly troubleshooting

Dear Friends,

Hope you all are doing well in life as well as in oracle apps also. Hhhh… :P

We are back again with some issues and solutions. Actually one of my friends asked me regarding performance tuning if forms are opening slow.

That time I gave him some ideas and promised him that I will back very soon with some more information. There are lots of factors which may impact the applications but there are some work around which can helpful fixed the issues.

One more thing I would like to tell, friends I shared my knowledge’s as per my real time experiences and real life experiences. So, there is not like just copying and pasting the stuff. As already I have shared my real life time stories which I have learned from my life.

So, let’s start now. Suppose, our forms are opening slow then what things we should be check and how to debug it. I will try to explain here and share my knowledge. I am sure; it will be useful because it’s having been experienced.

1. We should check which forms are opening slowly either any particular form or all forms.

2. If all forms are opening slowly for particular machine then clear the cache and try again. It can be machine speed slow, machine hardware and bandwidth speed.

If all forms are opening slow and for all machine then we really need to check below things such as:

A. Check whether Trace is enabled or disabled and if it is enabled then kindly disabled it.

B. Check the top commands if any resources are consuming high CPU usage.

C. Check for all InactiveSessions if it’s there then kill those sessions.

D. Check for deadlocks.

E. Every user should close the forms and logout properly.

But actually we don’t care. We just close windows tab at a time and left for break :D :P but that’s also impact our EBS internally.

F. A programmer if ran any program with infinite loops then this also cause a performance issue.

That’s why we need to write any program carefully. If program not properly then it may cause deadlock as also which I have explained it in my previous posts.

G. It can also be because of increasing the number of users. Also need to check users have one active session.

H. Check for the Performance Pack (Native I/O) is turned on for WLS.

And most and always we use this method.

If the users have issue for any custom forms then we should follow below steps which are easy and very effective.

When he run the program that time you should follow below steps:

1. Enable the Trace file.

Login to front-end -> Help -> Diagnostics -> Trace -> "Trace with Binds and waits” .

Then there will be a trace file generate under below patch:

$cd $ORACLE_HOME/admin/<$CONTEXT_NAME>/udump

Now you can run either Trace Analyzer or tkprof as shown below commands:

Trace Analyzer command:

[ora-data]$sqlplus apps/apps_password

SQL> START TRCANLZR.sql UDUMP ora-data_ora1919.trc;

TKPROF command:

[ora-data]$cd $ORACLE_HOME/admin/<$CONTEXT_NAME>/udump

$tkprof ora-data_ora_1919.trc ora-data_ora_1919.txt explain=apps/apps_pwd

Hope this may useful and helpful. We will come back again with new troubleshooting and solution as what we should do if forms opening slow after increasing the number of session.

    issues or advice. Maybe you can write subsequent articles referring to this
    article. I wish to read more things approximately it!

  4. Nice Blog. Can you please explain detail about particular form having slowness but not a custom form.


Thank you for your comments and suggestions. It's good to talk you.
