Upgrade from 6.1 SP2 to 7.1.7 - Could not reserve enough space for object heap

Issue while upgrading from 6.1 SP2 to Pega 7.1.7

Approach : Single schema to Split schema

Issue faced

  • We are facing the below issue while Executing the PEGA Upgrade Wizard (IUA) from a Windows Server 2008:

    Run Update Wizard:

    [java] Could not create the Java virtual machine.

    [java] Error occurred during initialization of VM

    [java] Could not reserve enough space for object heap


    F:\PRPC717\PRPC717_fullversion\pegaGuiInstallerTemp\build.xml:83: The following error occurred while executing this line:

    F:\PRPC717\PRPC717_fullversion\scripts\setupDatabase.xml:319: The following error occurred while executing this line:

    F:\PRPC717\PRPC717_fullversion\scripts\setupDatabase.xml:2284: Java returned: 1

    Total time: 234 minutes 15 seconds

    Below are the Application details :

  • Current PEGA environment : PEGA 6.1 SP2

  • Upgrade version : PEGA 7.1.7, 64 bit JVM

  • Database: DB2/AIX64

  • Split schema approach : Yes

  • Rule schema name : RXPQ

  • Data schema name : RXRF

  • 4 GB RAM

  • Enough disk space (PEGA recommendation is > 6 GB)

  • JVM version: 1.6.0_06 (build 1.6.0_06-b02)

Solution tried but failed

Updated the memory in the machine to Min – 512 MB and Max – 1536 MB which is also mentioned as a Resolution per PDN link below. https://pdn.pega.com/support-articles/could-not-reserve-enough-space-object-heap
