XPRAS_UPG error in DOWNTIME phase in EHP4

Question

Hi,
I am getting the below error in XPRAS_UPG in DOWNTIME phase of EHP4 installation in ERP 6.0 on HP-UNIX and Oracle.
XPRA ERRORS and RETURN CODE in SAPRW70104.HD1
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1AETR012XProgram terminated (job: "RDDEXECL", no.: "10302400")
  Long text:
    Cause
      Program "&V#&", which was started in the background, was terminated
      abnormally.
    System Response
      The system created a job log for the terminated program.
    What to do
      Proceed as follows:
      Log onto the system in which the program was executed. The system is
      specified at the beginning of the transport log.
      Then call transaction SM37 to display the job log.
      Enter "&V#&" as job name and "DDIC" as user name.
      Restrict the starting date to the starting date specified in the
      transport log.
      For the other selection criteria, select only jobs with the status
      "cancelled". Then press <LS>Execute</>.
      A list of the jobs satisfying the selection criteria is displayed.
      You can display the log by pressing <LS>Job log</>.
      If the list contains several jobs, you can select the job with the ID "
      &V#&" with <LS>Display</> -> <LS>Job details</> or define further
      details for the selection criteria in the initial screen of transaction
      SM37.
      If the ABAP processor reports cancellation, double-clicking on the
      corresponding message in the job log branches to the display of the
      corresponding short dump.

>>> PLEASE READ THE REPORT DOCUMENTATION OF THE REPORTS MENTIONED ABOVE <<<
XPRAs are application reports that run at the end of an upgrade.
Most XPRA reports have a report documentation that explains what
the report does and how errors can be corrected.
Call transaction se38 in the SAP system, enter the report name,
select 'Documentation' and click the 'Display' button.
>>> The problematic XPRAs are mentioned in messages of type PU132 above <<<
I was successfully able to umlock the system and in SM37 I could see the job log pointing to ST22. In ST22 we have many dumps related to error PXA_NO_FREE_SPACE. I found many notes in marketplace but all are referring the parameter abap/buffersize which needs to increased. I am a bit apprehensive about the fact that since we are in DOWNTIME phase and in the middle of XPRA execution phase should we increase the parameter and restart the system and then continue with the upgrade???
I have also tried to run the phase many times but the same error persists.
Please can anyone help me to come out of this problem.....
Thanks & regards,
Rozal

Hello Rozal,
You are correct XPRAS is a downtime 2 phase, but actually your system is up and running. It was started way back in phase "STARTSAP_NBAS" its just that you cannot use your system productively. XPRAS executes the XPRAS methods in the running system.
Its absolutely safe, you can change the parameter take a restart and continue further.
