Note:
This issue can happen with any of the WebCenter Managed Servers.
In this note we show the issue with the WLS_Spaces managed server. But you can use the same steps to start other managed servers having the same issue. Just replace the name of the managed server in the following steps depending on the affected managed server. For example, if using WebCenter 11.1.1.4.0 the WebCenter Spaces Managed Server is WC_Spaces. If using WCP 12.2.x, the portal managed server is named WC_Portal.
