The most efficient way to see what locks currently exist within your instance is to use the OEM Database Control (or Grid Control) You can get to this page by going to Database Control Home Page Performance Additional Monitoring Links Instance Locks The Instance Locks page shows all locks, both blocking and non-blocking Most of the locks you ll see are harmless; they are routine non-blocking locks Oracle uses to maintain concurrency To see locks that are causing contention in your system, choose the Blocking Sessions option from the drop-down list in the Instance Locks page The Blocking Session page will show you all the sessions that are currently blocking other sessions You can also go directly to the Blocking Sessions page by going to Database Control Home Page Performance Additional Monitoring Links Blocking Sessions.

After all these arguments against /clr:pure, you probably want to ask the question, Why should /clr:pure be used at all Well, there are two special restrictions of mixed-code assemblies that can be bypassed with /clr:pure. These restrictions are as follows: Mixed-code assemblies must be stored in files. Mixed-code EXE files cannot be loaded dynamically into a process. At first glance, both restrictions sound strange. It seems to be obvious that all assemblies are stored in files. However, it is in fact possible to use assemblies that are stored in different locations. For example, assemblies can be loaded from a byte array containing the assembly s data. For that purpose, Assembly::Load has an overload with an argument of type array<System::Byte>^.

The Blocking Sessions page shows the session IDs of both the blocking and the blocked sessions (see Figure 6-1) You can terminate a blocking session by selecting the appropriate session and clicking the Kill Session button Figure 6-1 shows that the user nick_alapati is holding an exclusive lock (on a certain row in the test01 table, which you can t see in the figure), thereby blocking the user nina_alapati from getting an exclusive lock on the same row The blocking session is identified by a value of 1 or greater under the Sessions Blocked column on the Blocking Sessions page (see Figure 6-1) The session that s being blocked is indicated by a value of zero You can also use OEM s Hang Analysis page (go to Database Control Home Page Performance Additional Monitoring Links Hang Analysis) to find out the exact wait status of the blocking and waiting sessions.

then notify "Error" $killoption $process $pid \ $curr_age $value "minutes of elapsed time" else test $debug -gt 0 && echo "process age ok" fi ;;

The Hang Analysis page will show you the following: Instantaneously blocked sessions Sessions in a prolonged wait state Sessions that are hung When there is a severe contention for locks in the instance, the Hang Analysis page will help you identify the problems much more quickly than running a SQL script, which might actually worsen the locking problems..

Be prepared to wait for a very long time when you run most of the SQL scripts that relate to locking situations. Also, be aware that some of the scripts might sometimes make matters worse. The utllockt.sql script, for example, creates a table to store locking information, and it needs to acquire locks to create this table, which might exacerbate the locking problems that you are trying to diagnose in the first place! It s smarter to schedule these scripts using a scheduling tool or the Oracle Enterprise Manager (OEM) and arrange for database alerts when there are problem locks in the system, so you can take action to fix the problem.
