While upgrading Experience Portal on Avaya Enterprise Linux, the Experience Portal database upgrade uses approximately 3.5 times the size of the database backup. For example, a system with a backup of 10 GB requires approximately 35 GB of free space in the /var partition for a successful upgrade.
Enter the command du -sk /var/lib/pgsql/data/base to determine the database size. The system displays the size of the database in kilobytes.
To prevent upgrade failure due to space constraints, monitor and estimate hard disk space usage during the upgrade process. The system retains some of the files used in the upgrade process for backup. However, you may either delete these files, or move these files to a different location during or after the upgrade to maximize the available disk space. The following table describes some of the database files used during upgrade, their locations, their approximate sizes relative to the database backup, and if you can delete or relocate these files safely. Avaya recommends you retain these files in a different partition or hard drive, for backup purpose.
| Description | Location | Size compared to database | When it is safe to delete | ||||
|---|---|---|---|---|---|---|---|
| Old Experience Portal database | /var/lib/pgsql/data/base | Approximately same as the database size |
After OS upgrade, and before you run the aepinstall command.
Ensure that the export file is present at /var/lib/pgsql/vp_upgrade.export.
|
||||
| Database export file |
/var/lib/pgsql/vp_upgrade.export_vp_<date>
Where <date> is the date of installation. |
Approximately same as the database size |
After the Experience Portal prerequisite installer successfully
installs the updated PostgreSQL database.
Ensure that the PostgreSQL field indicates Success. |
