Dispatcher not starting "Loading: ThreadManager returned false! "

[Former Member]

Hi,

The system was running fine for about two weeks and now the dispatcher will not start, we have upgraded the java server from windows 2003 to windows 7 and i did a system copy using the sapinst tool. This is a java only server using ABAP ume to connect.

Hers is the errors i am receiving:

SAP J2EE Engine Version 7.01 PatchLevel 75592. is starting...

Loading: LogManager ... 606 ms.

Loading: PoolManager ... 3 ms.

Loading: ThreadManager ...

Loading: ThreadManager returned false!

Kernel not loaded. System halted.

I also get this error:

Hi Jean,

I understand you mean Windows 2008 R2, no Windows 7 (this would be the client side).

Regarding the issue, you can start with note #711584. In fact this is very few infomration to understand why the dispatcher is not running. Did you receive any error during system copy?

Best regards,

If you are suing ABAP ume, have you done system copy for ABAP stack as well?

Is there any change in hostname?

Hi,

you said your system was running well for two weeks and now it will not start anymore. Did you check the gateway?

Can you ping that server? What's with an nslookup?

If you cannot connect the gateway it won't work. Maybe something in hosts-file or on the domain name server...

add the below code in  D:\usr\sap\ECC\SYS\global\ms_acl_info.dat

HOST=*

Hope this will solve you.

Reward if you really get helpful.

Hi,

thanks for your reply. The issue was with the global ThreadManager properties, for some reason the value was all set to 0. Once we have reset the value to default in the config tool and re-started the java, it was working fine.

The other issue with the Gateway host name, since this was a system copy, the gateway was never repointed to the new server.

Thanks again for your replies.

the hostname "old server" is unknown. Where did you put that name?

Dear Jean,

Hope you are doing good.

Not much investigation can be done with:

"

Loading: ThreadManager returned false!

Kernel not loaded. System halted.

"

Just retrigger a server restart and then check the below logs. You will definitely find more information on the error:

/usr/sap/<SID>/work/ dev, std and jvm*

and

/usr/sap/<SID>/JC<nr>/j2ee/cluster/server0/logs/default trace (latest).

Thank you and have a nice day :).
