In addition to the requirements listed in Hardware and Software Requirements, verify that your system meets the requirements listed below for running HADB.
HADB is only bundled with the Application Server 9.1 Enterprise profile. Also note that the Java components of the system have been built with JDK 5 and has been tested on JDK 1.5.
Solaris (SPARC) – Solaris 8 MU7, Solaris 9 MU7, Solaris 10 RR.
Solaris (x86) – Solaris 9 MU7, Solaris 10 RR.
RedHat Enterprise Linux - 2.1 U5 (only ext2 file system is supported, not ext3), 3.0 U4 (both ext2 and ext3 are supported. Updates before U4 are not recommended due to excessive swapping). Note that HADB is tested on these operating system versions in 32–bit mode only. Also, note that HADB does not support RedHat Enterprise Linux 3.0 running in 64–bit mode due to a bug in the operating system (see known bug 6249685 in the High Availability section for details about impact on HADB).
Microsoft Windows – Microsoft Windows 2000 Advanced Server Service Pack 4 and Microsoft Windows 2003 Enterprise Edition. Note that HADB does not support any of the forthcoming Microsoft Windows operating system versions in 64–bit mode.
Minimum memory - 320 MB per node.
Minimum free disk space - 70 MB for HADB binaries per host. In addition, disk space is needed for the data devices, 512 MB for a test installation per node.
Recommended memory - 512 MB per node.
Recommended free disk space - 70 MB for HADB binaries per host. In addition, disk space is needed for the data devices, 1200 MB for a test installation per node.
Make sure write caching is disabled on devices storing HADB data and log files. Write caching is enabled by default on some Solaris platforms; for example, Solaris x86.
