After you register and install your target version, but before you proceed with an
Express Upgrade, verify that the symbolic links to the SAM and Schema Registry configuration
directories on each host are still valid. If the links are not valid, fix them before
upgrading.
-
Confirm on each host running Registry or SAM that symlinks for the configuration
directories are still valid.
#For Schema Registry
ls -l /etc/registry/conf
#For SAM
ls -l /etc/streamline/conf
-
If the link appears to be broken, perform the following steps to fix it.
- Remove the broken symbolic
link.
#Remove broken Schema Registry link
rm -rf /etc/registry/conf
#Remove broken SAM link
rm -rf /etc/streamline/conf
- Create a physical SAM or Schema Registry configuration
directory.
#Create a Schema Registry conf directory
mkdir -p /etc/registry/conf
#Create SAM conf directory
mkdir -p /etc/streamline/conf
- Copy the configuration files from your backup, into the new
directory.
#Copy Schema Registry backup files
cp /etc/registry/conf.backup/* /etc/registry/conf
#Copy SAM backup files
cp /etc/streamline/conf.backup/* /etc/streamline/conf
