Internal kernel error - ZDATE_ILLEGAL_LOCTIME

[#1]

Hi Everyone,

I have SAP servers in Active directory. but recently, i am getting the following Runtime error in 2 servers.

Runtime error - Description of Exception

Category                       Internal Kernel Error

Runtime Error                ZDATE_ILLEGAL_LOCTIME

Application component  BC-ABA-LA

Short text

The local time of the application server is not correct.

The database and the application are installed in a same server.

Steps taken:

1. Trying to sync the time between active directory server and the application server.

2. Checked the time zone and all are OK.

3. Finally, I restarted the server and it is working now temporarily.

I got this error few times and only the last step has helped me. I think, this is not recommended.

Is anyone have idea about this issue and any other checklist to verify?

Hi Pandiyaraj,

The reason of this dump is described details as in note 447839:

Reason and Prerequisites

The system time of the server was reset to the past, while the SAP

application server was running.

In this case, it does not matter whether this was done manually (with

operating system commands) or automatically (with a "time service", for

example).

If the runtime error ZDATE_ILLEGAL_LOCTIME has occurred, the most

important information is contained in the dump.

When the runtime error ZDATE_ILLEGAL_LOCTIME occurs, the relevant

application server should be shut down immediately.

1.Make sure your OS and SAP has the same timezone.

  Ohterwise dumps like ZDATE_ILLEGAL_LOCTIME will happen.

2.The tool "SapTimeTrace" is added to note 447839. This is a small

executable which you can simply execute in a command line as follows:

SapTimeTrace 5

Now the operating system time is analyzed every five seconds and a trace

file (SAPTTrc.trc) is written into the current directory that contains

information about the time changes. For more information, call the

"SapTimeTrace" without parameters.

Thank You.

Regards,

Deepika
