Hi,

You can get good solution of your problem if you explain in some more words.

But it is always suggested to keep your system on latest SP and latest kernel level patch to get rid of unexplainable problems.

Hi,

Please try to look into following.

1) Do you have BG threads available in the system ? If Threads are not available at the time of Transport trigger, Truck will keeps on going.

2) Please try to look for .LOC file at the location /usr/sap/trans/tmp. This indicates Transport Lock and trcuk will keeps on going in such cases also.

Perfect!!

Good information!

How a transport can be locked? for example... I know that the .LOC file is created because a transport is locked but what can be the reason for which the transport is lock?

Thanks again!

Hi,

This kind of scenerio can happen...

1) If some one wants to import more than one transport at a time in the system.

2) If one transport is getting imported and some one trigger one more transports

3) There may be some more scenerios also....I have told whatever I have seen....

Please check whether the filesystem /usr/sap/trans is properly mounted in all the hosts ( All App. Servers and CI). Please ckeck the RDD* jobs. In case of a transport hang situation ( In this situation you can view so many truck sign in the import buffer), go to Import monitor and kill any transport request having the truck sign for a long time.

The transport hang situation may occur for the following reasons:

1. Filesystem /usr/sap/trans is not properly mounted in All App. Servers and CI

2. RDD* jobs are failing.

3. Kernel patch level is very old

4. Oracle client is not properly upgraded to the latest oracle release of the system
