Unable to Login to OAM Console after changing the Default System Store

Version:-OAM 11.1.2.3.0

CAUSE

At the time of creating Identity Store. The option of "This is the System Store" option was selected.
It is recommended to keep "Embeded LDAP Server" as default identity store.

SOLUTION

1) Goto location /uo02/Oracle_IDM1/common/bin
    Where Oracle_IDM1 is the Oracle home of the IAM Suite

2) Execute the below mentioned commands
    /u02/Oracle_IDM1/common/bin>wlst.bat  or wlst.sh
    on Unix Systems
    wls:/offline> connect()
    Please enter your username :weblogic
    Please enter your password :
    wls:/OMS/serverConfig> displayUserIdentityStore('UserIdentityStore1')
    wls:/OMSbase_domain/serverConfig>                                                   
    editUserIdentityStore(name="UserIdentityStore1",isPrimary="true"
    ,isSystem="true")

3) Restart all your managed servers.

4) Verify if you are able to login as Weblogic user or not.






Thanks,
Aditya.

Cause:-

DB is down and listener is not up and running.


Solution:-

1. Open new terminal and check with lsnrctl status
2. Check DB connectivity through sqldeveloper
3. Contact DB team and ensure that DB and listener are up and running.

Resolution:-

Though it is safe to operate with the smaller buffers it is recommended that you configure your OS to allow for larger buffers.

On Linux execute (as root):-

Go to /etc/sysctl/conf fine and change below value

sysctl -w net.core.rmem_max=2096304

sysctl -w net.core.wmem_max=2096304
