SerializedSystemIni.Dat recover in Weblogic

Oracle Weblogic Server

While starting WebLogic Server fails to initialize and the following exception used to get thrown

<Critical> <WebLogicServer> <BEA-000362> <Server failed. Reason: [Management:141266]Parsing Failure in config.xml: weblogic.descriptor.ResourceUnavailableException: Missing SerializedSystemIni.dat> service failed. The server will shut itself down>

We came to know that SerializedSystemIni.dat is used for encryption/decryption of plain-text/ciphertext within a WebLogic domain.

If missing or corrupted, then the decryption failure prevents WebLogic from initializing.

Please follow the below steps to recover SerializedSystemIni.dat file:

1. Go to $DOMAIN_HOME/config folder and open the config.xml file and remove any encrypted sections from the <credential-encrypted> attributes.
2. Replace its content with “”.(NULL) and save the file.
3. Go to $DOMAIN_HOME/servers/AdminServer/security and remove the file(if exists).
4. Go to $DOMAIN_HOME/security and remove SerializedSystemInit.dat.
5. Go to $DOMAIN_HOME and rename the to
6. Open and Change all the hashed passwords (encrypted passwords) to clear text passwords and save the file.
For example:

user.system=0xaasmme787xs5ff739b5536904c to user.system=password

Notes: Use the same password that was set to the domain.
7. Open a terminal and go to $DOMAIN_HOME/bin and execute (or .cmd).
8. Once the domain env is setup correctly, execute (in the same open terminal) the following command to regenarate SerializedSystemIni.dat and files :

java SerializedSystemIni.dat

9. Once the above two files regenrated, open located at $DOMAIN_HOME/bin and add below mentioned argument in JAVA_OPTIONS and saev the file:


Note: This will recreate the file.
10. Start Weblogic with or startWeblogic.cmd and enter the user and password.

    Hi.. nice tutorial on resetting the keys. However it is failing on my end. Complaining about credential-encrypted being empty.

    Server failed. Reason: [Management:141266]Parsing failure in config.xml: java.lang.IllegalArgumentException: In production mode, it’s not allowed to set a clear text value to the property: CredentialEncrypted of SecurityConfigurationMBean.

    Did all the steps… in the end when you start weblogic with … it never prompts for username/password….?

    Should I also have removed *.ldift files from $domain/security ? Might try that…. before I regenerate Serial.dat

    Any other ideas?
