Java Engine for PI not coming up

[Former Member]

Hi Experts,

I am having problem bringing up my Java Engine of SAP PI (NW 7.1). the ABAP engine comes up fine.

I started getting this error after I copied over the user database from another PI system and restarted the system.

Looks like SAPJSF and SAP_GUEST passwords got changed. I have reset the password for SAPJSF in ABAP and also I have changed the parameter for ume.login.guest_user_uniqueids from J2EE_GUEST to J2EE_ADMIN. That has not helped either.

Fid security log below for reference.

Hi,

Check your number of gateway connections in tcode SMGW and also TCP/IP RFC. Also as said above by Gaurav change the passwords of reseted passwords to the old/earlier passwords it will work.

Please change password of all SAP PI service users to their respective previous password. I guess when you copied user database then all services users are changed hence RFC connection between Java and ABAP is not working which seems to be cause of this issue.
