 Dbvisit Standby installation fails with "Can't locate libperl.so" error.

Problem Details

Error: Can't locate libperl.so

When installing Dbvisit Standby and you get the following error: Error: Can't locate libperl.so. For example:

oracle@dbvlin103[/home/oracle/7.0/dbvisit/installer]: ./install-dbvisit
Error: Can't locate libperl.so
Make sure the ActivePerl bin directory is in your PATH
PATH=/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin

When Dbvisit Standby is executing, including Dbvnet and Dbvserver, temporary files are extracted and used from the default system temp location. On most Unix system this will be /tmp.

The problem in this case is that the /tmp mount point was mounted using the noexec option.

Using the mount command you can quickly review the settings:

oracle@dbvlin103[/home/oracle/7.0/dbvisit/installer]: mount |grep tmp
tmpfs on /dev/shm type tmpfs (rw,size=2G,rootcontext="system_u:object_r:tmpfs_t:s0")
tmpfs on /tmp type tmpfs (rw,noexec,size=2G)

This might be seen in some cases where environments are locked down.

There are two possible options to get around this:

1. Ask the system administrator to mount the /tmp filesystem without the noexec option.

2. Create a new temporary directory and set the TMPDIR environment variable to point to this location. For example:

   oracle@dbvlin103[/home/oracle/7.0/dbvisit/installer]: mkdir /home/oracle/tmp
   oracle@dbvlin103[/home/oracle/7.0/dbvisit/installer]: export TMPDIR=/home/oracle/tmp
   oracle@dbvlin103[/home/oracle/7.0/dbvisit/installer]: ./install-dbvisit
   
   Welcome. Your Dbvisit product is going to be installed in a moment. It will be required by you to enter some configuration parameters
   during installation.
   
   It is recommended to make a backup of our current Dbvisit software location for rollback purposes.
   
   INSTALLATION DIRECTORY
   Please specify the Dbvisit main installation directory.
   The default directory is "/usr/dbvisit".
   Note: the various Dbvisit products and components - such as Standby,
   Replicate, Dbvnet, and Dbvserver - will be installed in the appropriate subdirectories of this path.
   Enter a custom value or press ENTER to accept default [/usr/dbvisit]:

If you have to look at using TMPDIR option you will need to make sure you update the .bash_profile or .profile or other environment configuration files to ensure that this path is set before you execute Dbvisit Standby processes.
