JPS-01050: Opening of wallet based credential store failed. Reason java.io.IOException: PKI-02002: Unable to open the wallet. Check password

Hi, All today I hit with very wired problem and later got solution using some Oracle post, so though to share in my blog as well.

I just did fresh domain creation and while starting the domain using ./startWeblogic.sh script I was getting below error.

Initially I though, while creating domain I gave some wrong password for "weblogic" user, so deleted the domain and re-created again, but again while starting I got same error. Second time I again thought I might gave wrong password while creating domain, I deleted it again and created Domain third time.

However, this time also same error poped-up, then I started googling on this issue and found solution. 

Error Message:

<Oct 28, 2014 12:44:48 AM EDT> <Critical> <WebLogicServer> <BEA-000386> <Server subsystem failed.

Solution:

open putty session from root user and run below command -

root> chmod -R 777 /tmp

Note: I really don't know relation between the weblogic error message and the solution which works for this, however above solution work in my case, and I was able to start the Admin server.
