Upgrade Performance Considerations

Ensure that you consider mart size, model count, and associated versions while upgrading a Mart from an earlier version to the latest version. The following table provides sample data of the upgrade process. You can use this information as a guideline.

Mart Database

Following are a few tips to ensure a smooth upgrade:

  • Before upgrading, ensure that you double the number of data files in tablespaces for MMDATA and MMINDEX in an Oracle mart.
  • Check the Report Upgrade status in the MartServerUpgrade.log file.
  • If the M9Object Table has high volume of data and models over 100 MB, run the upgrade on a machine that has 64 GB or more RAM.
  • For 64-bit operating system, based on the following parameters, change the number of threads from the default 8 to 3 in the user.config file located at C:\Users\<user name>\AppData\Local\erwin\MartConfiguration.exe_Url_<xxx>\2.0.0.0\:

  • In case of failures in upgrade, before you rerun the upgrade, ensure that you select the following check boxes on the Advanced tab on the erwin Mart Configuration dialog:
    • Rerun Count Upgrade
    • Rerun Report Upgrade
    • Rerun Report Upgrade For All Models
