Weblogic Admin server not starting

Weblogic Admin server not starting, was giving a server subsystem failed error, pointing to Embedded LDAP error. Turns out there was a corrupt file replicas.prop. Delete this file and start the Admin server again. Probable cause is disk being full.

VMware fix for Invalid manifest and ova file import failed errors

Image
Recently we got a OVA file for a virtual machine. The vendor instructions were to import the ova file in vmware Workstation, Player for Windows/Linux, Fusion for Mac, and VirtualBox as well.  The instructions were to take the available package and launch the VM with VMware workstation. The package contained  Module.mf, Module.ovf and Module-disk.vmdk and a Module.ova file. The .mf and .ovf file were 2 KB each whereas the vmdk was several gigs. The package also contained a Module.ova file which was several gigs as well. OVF           Open Virtualization Format MF             Manifest file VMDK       Virtual Machine Disk OVA           Open Virtualization Appliance The ovf file is a xml file that contains metadata for the ovf package The mf file contains the SHA1 hash codes of all files in the package The vmdk file is the disk image of the virtual machine,  VMware Workstation or VirtualBox.

SOAPUI - import certificate

Note: SoapUI has two versions, one is open source and second Professional version. The open source can be download here . (confirmed link 12/19/2018). SSL Handshake issue:   There is an Issue in SoapUI version 5.3.0 (and 5.2.0 version) with SSL handshake error. It was resolved by updating below in vmoptions file ( refer here ). However, the error that shows up while trying to load wsdl is "Error loading WSDL" as below The fix is to Enable TLS 1.2 protocol for SOAP/REST calls in SoapUI, by ammending the vmoptions file to add the directive for TLS as (-Dsoapui.https.protocols=TLSv1.2). Refer here . Update: Version 5.5.0 does not have this issue. If you are on 5.3.0 better upgrade to 5.5.0 which is available now (Feb 2019).

Session Timeout in Oracle Access Manager

Image
Session Timeout in Oracle Access Manager (OAM) The session lifetime and Idle timeout entries control how long a user's session is valid. In OAM, a user session is an object which represents an authenticated user. This object is stored in the server memory and if Database session persistence is enabled, this object is stored or available in the database. Each session is unique and is identified by both a userid and Session ID (session identifier), see screenshot below "OAM User Session Management".  A valid session means a user has been authenticated with OAM. A session can have following three states: 1) active 2) inactive 3) expired When a session is created it is in active state and is available as an object in the OAM. After a set time - idle timeout, the session moves or transitions to inactive state. And finally after the Session Lifetime time, the session is marked as expired. Expired sessions are removed from server memory. Read more about Session Lifetime
