System requirements for ORA.mirror
Operating system / permissions:
Windows 2000 or higher.
Recommendation: The same version installed on every host.
- Administrative Shares on all harddiscs like C$, D$, ect.
Mutual writing and reading access for the logged on user to the administrative shares.
(\\primary-host\c$ <-> \\mirror-host\c$). ORA.mirror could run under RunAs. We recommend SteelSonic RunAs.
- Runs on virtuell machines too.
- The mirror hardware must not be a performant server. It could be a simple desktop.
- The number of hard disks must be identical on PRIMARY and MIRROR. You can use "subst" on mirror to create a disk.
- The capacity of the hard disk on the mirror must be sufficient for the complete data files and archivelogs.
- The RAM of Mirrors must not be the same on primary. But have a look to init.ora.
- The mirror must have the same version of Oracle including patchlevel. (Version, Patch, Edition)
- The pre-installation of a database with the same SID as on PRIMARY on MIRROR is recommended. You don't have to copy the hole database. A small test-database is sufficient.
- The password for the database users "SYS" and "SYSTEM" must be known.
- The primary database must be in ARCHIVE_LOG mode.
- The Oracle-Edition does not matter. ORA.mirror supports Oracle XE to Oracle Enterprise in versions 9i to 11g.
- For the installation and operation of ORA.mirror are no extensive Oracle experience required.
- Dealing with sqlplus such as establishing a connection to the database and send simple commands should be familiar.
- Knowledge of data backup and recovery is assumed.
