Virtual machine virtual disk grows very huge over time despite the fact that the guest os is not taking the space shown by the vmware virtual disk files. This examples shows how to reclaim unused space using command line tools like vmware-mount and vmware-vdiskmanager. The size of the virtual machine partitions, output of ls from the guest os   The total used space is only 10gb or so The size of the virtual disk files on the host To list the partition on a virtual partition use vmware-mount -p ex: vmware-mount -p /u02/vm/vm_test_for_prod_handson/vm_test_for_prod_handson.vmdk Partition has to be mounted to prepare it for shrinking, create a folder to mount the virtual machine partition mkdir /tmp/vm Mount the virtual disk partition vmware-mount /u02/vm/vm_test_for_prod_handson/vm_test_for_prod_handson.vmdk 1 /tmp/vm (This will mount the first partition) Now start pre

Online Patching Enablement patch: 13543062:R12.AD.C. ORA-44305: service ebs_patch is running ORA-06512: at "SYS.DBMS_SYS_ERROR", line 86 ORA-06512: at "SYS.DBMS_SERVICE", line 454 ORA-06512: at "SYS.DBMS_SERVICE", line 375 ORA-06512: at "APPS.AD_ZD_PREP", line 308 ORA-06512: at line 4 Checked the error message with oerr utility oerr ora 44305 44305, 0000, "service %s is running" // *Document : Yes // *Cause    : The specified service was running. // *Action   : This message is informational only. Actually the line 308 in package APPS.AD_ZD_PREP is where the error is happening. The  line 308 in the package APPS.AD_ZD_PREP is executing the procedure dbms_service.start_service, as the service is already running the said error was thrown. So dbms_service.stop_service is executed explicitly to stop the service and adctrl is used to restart the failed worker. The adpatch continued to run and completed successfully.
