Fast Response Cache Accelerator (FRCA) is Now Supported on AIX

AIX 5.1 and 5.2 Fast Response Cache Accelerator (FRCA) feature is now supported in IHS 2.0.47. For AIX 5.2, APAR IY49388 (fixed in PTF U495388 or ML 52B) is required.

Separate Download of IBM Directory Server (IDS) Client is Not Required

In previous versions of IHS, to use the mod_ibm_ldap module, a separate IDS Client was needed. For this release, this requirement has been removed. A separate download of the IDS Client is no longer required on any supported platforms.

Environment Variable Needs To Be Set When Running With SSL on SuSE SLES 8 (United Linux 1.0)

On SuSE SLES 8.0 (United Linux 1.0), please set the following environment variable before starting IHS 2.0.47 with SSL enabled (otherwise, IHS 2.0.47 will not start):

export LD_PRELOAD=/usr/lib/

FIPS Support is Now Available

IHS 2.0.47 provides support for FIPS 140-2. To enable FIPS support, add SSLFIPSEnable directive to the httpd.conf file. Similarly, use SSLFIPSDisable directive to disable FIPS support.

FIPS support is disabled by default.

xlC.rte 6.0 Runtime is Needed When Running IHS on AIX 5.1 or AIX 5.2

On AIX 5.1 or AIX 5.2, please make sure that the xlC.rte 6.0 runtime library (for example: xlC.rte. is installed before installing IHS 2.0.47. This runtime library is needed to install and use SSL with IHS 2.0.47 on these versions of AIX. This runtime library can be installed from the AIX 5.2 CD. However, it is not available on the AIX 5.1 CD. It can be downloaded from Fix Delivery Center for AIX 5 and AIX 4.3 web site.
