Applies to:

All versions of Cryptshare Server

Symptom:

After rolling back to a previous version the Cryptshare Server is not available.

Cause:

The Java installation folder has not been restored.

Solution:

There are three approaches to restore Java:

1. Java backup is stored in the Cryptshare installation folder 
2. Java backup is in the pre-update backup
3. Java backup is not contained in the pre-update backup

1. Java backup is stored in the Cryptshare installation folder

How to restore Java from direct backup

ls -lh /opt/cryptshare-3


# run the following command, to restore the Java installation
unzip -q /opt/cryptshare-3/jre8Backup.zip -d /opt/cryptshare-3/
mv /opt/cryptshare-3/jre8_BAK/ /opt/cryptshare-3/jre8
ln -s /opt/cryptshare-3/jre8 /opt/cryptshare-3/jre8_x64
chmod 755 /opt/cryptshare-3/jre8/bin/java


# run the following command, to start Cryptshare service
systemctl start cryptshare (use rccryptshare start up to and including v.7.1)

2. Java backup is in the pre-update backup

How to restore Java from pre-update backup:
# unpack the pre-update backup to the temp folder
mkdir /tmp/pre-update
unzip -q /opt/cryptshare-3/backup/pre_update_<DATE>_.zip -d /tmp/pre-update

# run the following commands, to restore the Java installation
mv /tmp/pre-update/system/jre8 /opt/cryptshare-3/
ln -s /opt/cryptshare-3/jre8 /opt/cryptshare-3/jre8_x64
chmod 755 /opt/cryptshare-3/jre8/bin/java
rm -rf /tmp/pre-update


# run the following command, to start Cryptshare service
systemctl start cryptshare (use rccryptshare start up to and including v.7.1)
