Siebel SQLs/Error Messages >  SBL-SVR-01042: Internal: Communication protocol error while instantiating new task SBL-CSC-00301: Invalid value 10 for argument Maximum Tasks

SBL-SVR-01042: Internal: Communication protocol error while instantiating new task SBL-CSC-00301: Invalid value 10 for argument Maximum Tasks.


This error came when we tried to run Generate New Database for a Siebel Server.
I had run this command in the Server Manager


srvrmgr> run task for comp GenNewDb server SiebelServer1 


SBL-ADM-60070: Error reported on server 'SiebelServer1' follows:

SBL-SVR-01042: Internal: Communication protocol error while instantiating new task

SBL-CSC-00301: Invalid value 10 for argument Maximum Tasks.

SBL-CSC-00301: Invalid value (null) for argument (null).SBL-SVR-00102: Internal: No more items/objects found.

List Tasks for  compdef GenNewDB server SiebelServer1
Gave no running tasks

 

This command however seemed to suggest that there were to many tasks running.

srvrmgr>  list advanced param %MaxTask% for compdef GenNewDB


PA_ALIAS                                                                      PA_VALUE

HonorMaxTasks                                                                 False

MaxTaskHistory                                                                20

So I changed the number of Maximum Tasks 

srvrmgr> change param MaxTasks=15 for compdef GenNewDB server SiebelServer1Command completed successfully.

MaxTaskHistory  is probably how many Tasks will be in Server Manager cache.

Then I tried running GenNewDB again and had a similar error 

srvrmgr> run task for comp GenNewDb server SiebelServer1 


SBL-ADM-60070: Error reported on server 'SiebelServer1' follows:

SBL-SVR-01042: Internal: Communication protocol error while instantiating new task

SBL-CSC-00301: Invalid value 15 for argument Maximum Tasks.

SBL-CSC-00301: Invalid value (null) for argument (null).

SBL-SVR-00102: Internal: No more items/objects found.


So I tried changing Max Tasks parameter back to default value , which is one.


srvrmgr> change param MaxTasks=1 for compdef GenNewDB server SiebelServer1


After that, there were no more errors!


There is a document in Oracle Support Web Doc ID 2032171.1  that addresses this error.The solution there was to run this command


srvrmgr> change param MaxTasks=1 for comp GenNewDB server SiebelServer1


That did not work for me, we need to change the Parameter in compdef GenNewDB   and not comp GenNewDB


This was our error log messages :
