J2ee engine does not come up after the assignment of the UME to production.

I have created new client 121 from data 000 and User master data from

001 with profile SAP_ALL.

I assigned the UME to the new production client 121 by changing value

of ume.r3.connection.master.client to 121

in cluster-data -> Global server configuration -> services ->

com.sap.security.core.ume.service. Now after these changes J2ee engine

does not come up and if I revert the changes back mean taking UME back

to 001 client J2EE engine comes up. I have checked the password even for SAPJSF and J2EE_ADMIN in ABAP as well as configtool they are the same.
