Portal v7.0 not starting - Previous initialization was not successful

The problem is that now all of a sudden, the wps application starts before the wps_scheduler application, and that is what is causing the problem. To fix it, check the following:

1. Start the WebSphere_Portal server if it is not already started.
2. Try and access the WAS admin console:

http://<portal hostname>:10042/ibm/console

3. Navigate to Applications -> WebSphere Enterprise Applications
4. Pick the 'wps' application and go to 'Startup Behavior'. Check the
Startup Order. The default value is 10. If you have to change this,
do so now.
5. Go back to 'wps' and click Manage Modules.
6. Click 'WebSphere Portal Server'. It's starting weight should be
10000. If you have to change this, do so now.
7. Back in Manage Modules, click 'WebSphere Portal Server WSRP
Facade'. It's starting weight should be 10000. If you have to change
this, do so now.
8. Back in Manage Modules, click 'WebSphere Portal XmlAccess Facade'.
It's starting weight should also be 10000. Again if you have to change
this, do so now.
9. Now back to the list of applications, pick 'wps_scheduler' and go
to 'Startup Behavior'. It's startup order should also be 10. If you
have to change this, do so now.
10. From wps_scheduler, go to Manage Modules.
11. Click 'WPS Task Scheduler'. It's starting weight should be 5000.
If you have to change this, do so now.
12. Save all changes and restart Portal.

Also verify if <portalserver_dir>\wps.propeties file exists and it has required permission. If required rename that to a different file and created a new wps.properties and copied the contents of it and restarted.

If nothing works then try to backup and redeploy wps.ear: http://www-10.lotus.com/ldd/portalwiki.nsf/xpDocViewer.xsp?lookupName=IBM+WebSphere+Portal+8+Product+Documentation#action=openDocument&res_title=Redeploying_the_portal_EAR_file_wp8&content=pdcontent&sa=true
