Problem Cause : even if you delete the page some times objectID will not be deleted immediately from the portal databases . This is because scheduler (clean up) run in particular times (not immediately)

Solution: need to run the task.xml (you can get the example from /portalserver/doc/sample-xmls). Use like below

C:\Program Files\IBM\PortalServer\bin>xmlaccess -in D:\sf\export\task.xml -user wpsadmin -password wpsadmin -out c:\export\xmlout4.txt -url http://localhost:10038/wps/config

Then you can execute the XMLAccess to create pages

C:\Program Files\IBM\PortalServer\bin>xmlaccess -in D:\sf\export\pageExport .xml -user wpsadmin -password password -out D:\sf\export\xmlout3.txt -url http://localhost:10038/wps/config
