Hi,

The error indicates missing or inactive message/enqueue server or network problems.

Please follow the steps below to help troubleshoot the problem

1. Logon to each server separately and goto SM12->Extras->Diagnostics to test the connections for the enqueue server. This will test the access of each server.

2 Use SMGW and SM59 to test the RFC connections. See SAP Note 47682.

You may want to have your network administrator/Basis people test the connections & analyse the network.

Use the message server/logon group testing tool "lgtst" (Note 64015), & the "niping" program (Note 500235) to diagnose the network.

Have a look at attached note 124562 in order to check if you have a hostname resolution problem.

Check your DNS / network setting that this kind of problems can not lead to blocking situations of the dispatcher.

To avoid the blocking of the dispatcher you can set the parameter

rdisp/reverse_name_lookup = 0 to avoid such situations.

Best of luck.

Rgds,

Colum

I have Used the diagnostics tools as you suggested and i get the following on the top part:

Error: Address Lock server is not listed in the message server:

Error: System has no lock management

Then under Diagnosis area, there are a number of errors as follows:

Error: No Lock server connected to message server

Error: System error during lock operation

Error: Unexpected error occured in lock operation. SY-SUBRC= 8.

in transaction SM21, i also have various error messages including:

Error calling the central lock handler.

Dequeue All call failed.

Unable to reach central lock handler.

Previous message was suppressed 24 times.

Please analyse and assist.

Did You checked in DEFAULT.PFL profile parameters:

enque/serverhost = <server with enqueue service>

enque/serverinst = <instance no>

and maybe enque/process_location = REMOTESA ? ? ?

Before installing BI content, please simulate the same to find if there is any error
