Solution to : "WARNING: Detected too many memory locking problems."

Solution to : "WARNING: Detected too many memory locking problems."



My alert log file was generating too many warnings that i was not aware of. After a thorough search in Google (special thanks), i found that one file permission was responsible for generating the warning.
My alert log file entries:


Current log# 3 seq# 4645 mem# 0: <DATAFILE_LOCATION>/redo03.log
Mon May 28 11:53:39 2012
WARNING: Detected too many memory locking problems.
WARNING: Performance degradation may occur.



The real cause of those warnings is the file oradism located on $ORACLE_HOME/bin folder was lacking permission.

As per meta link note 374367.1, issuing the following command should stop the warnings to get generated:

1- cd $ORACLE_HOME/bin

2- chmod 4550 oradism
3- chmod g+s oradism
4- chown root:dba oradism 
5- Bounce the database


These commands ware generating errors on my case so i just made my oracle os user, the owener of this file. and bounced the database. And guess what? the problem was resolved. The oradism warning does not appear in the alert log after the permissions were changed.

Solution of problem: Resultset Exceeds the Maximum Size (100 MB)

Solution of problem: Resultset Exceeds the Maximum Size (100 MB) I was running a select statement in PL/SQL Developer. it was a short query but the data volume that the query was fetching was huge. But when ever i Click the button Fetch Last Page or press 'ALT+End' button a message box comes after a while saying: Then I started looking for the exact reason of this sort of problem in Google. When I realized there was no direct solution in the web, I started looking the PL/SQL Developer Software menu and found the ultimate solution. The reason of this problem is there is a parameter of maximum result set size in PL/SQL Developer Software which is by default set to 100 MB. To change this parameter you have to go to the following location: 1. Goto Edit Menu and click ' PL/SQL Beautifier Options '. A new window will open. 2. Click SQL Window of " Window Types ". 3. Now Change the value of "Maximum Result Set Size( 0 is unlimited)"  ...
