Uninstallation issues

Problem: Invoking an HPE ITOC uninstallation results in an error.

Symptom

When you run #<install_dir>/ITOC_Installation/Uninstall_HPITOC, an error message appears, and uninstallation fails.

Failure message

No Java virtual machine could be found from your PATH environment variable. You must install a VM prior to running this program.

Solution

Set the environment variable and retry:

$ export PATH=<install_dir>/openjre/bin:$PATH

$ <install_dir>/ITOC_Installation/Uninstall_HPITOC

Problem: After uninstalling HPE ITOC on a setup that has ITOC-included PostgreSQL, you may find an orphaned PostgreSQL process.

Symptom

During uninstallation, HPE ITOC services are stopped before uninstalling the PostgreSQL database, but there may be open connections to it through other clients. The uninstallation process removes what it can.

Solution

Kill the PostgreSQL process manually after uninstallation.
