ObjectStore Installation and License for Solaris

Chapter 3

Preparing to Upgrade

This module describes information and instructions for systems already running ObjectStore. If you are installing the C++ interface to ObjectStore for the first time, go to the next module, Chapter 4, Installing ObjectStore C++ Release 5.1.

Before you upgrade ObjectStore, read the ObjectStore C++ Interface Release Notes. In particular, you must be familiar with the contents of Chapter 1, New in Release 5.1.

This chapter covers the following topics:

Backing Up Your Data

Before you install ObjectStore C++ Release 5.1, be sure to back up your ObjectStore databases, using osbackup or oscp.

It is crucial to back up your data in case a database is inadvertently corrupted during the upgrade procedure.

Backing up to disk
For example, if you want to back up databases on the host kellen to the file /home/mydbs.bak with osbackup, use a command similar to

osbackup -r -f /home/mydbs.bak kellen::/
Backing up to tape
When you back up to tape, you need to know the size of your tape, so you can specify that the backup be in increments that fit on the tape. Use the tape size number with the -s argument. For example:

osbackup -r -f /dev/rmt/0 -s 150M kellen::/
You can determine the size of your databases to calculate how many tapes the backup requires. To obtain the size of the databases, run osdf hostname. The number displayed in the Used column (expressed in units of 1 KB) specifies the rawfs database size.

Upgrading Rawfs Installations

Checking for rawfs partitions
If you are unsure whether you have rawfs partitions, look in each $OS_ROOTDIR/etc/ hostname_server_parameters file for which you have a Server installed for lines similar to the following:

PartitionN:                  / pathname 
Such a line indicates that you have a rawfs on that Server. If you are unsure if a Server is installed on a particular host, or you are unsure which host names should be used, look in $OS_ROOTDIR/etc/ hostname_server_parameters for lines containing PartitionN.

The installation dialog prompts you about upgrading at the appropriate time. Continue with Installing ObjectStore C++ Release 5.1.
