Known Restrictions, Problems, and Workarounds
1-6 Oracle Database Installation and Administration Guide
■ Dynamic, or Private Ports, or both, from 49152 through 65535
Fujitsu documentation for TCP/IP on BS2000 recommends setting the privileged port
to 2050. However, using a registered Oracle port number may cause conflicts (see
http://www.iana.org/assignments/port-numbers ). For example, if you set the port
number for the listener process to 1521, then any Oracle process that listens on such a
registered port number may fail with the following error:
TNS-12545: Connect failed because target host or object does not exist
TNS-12560: TNS:protocol adapter error
TNS-00515: Connect failed because target host or object does not exist
BS2000 Error: 126: Can't assign requested address
BS2000 BCAM-RC: 40010020
The workaround is to use a non-privileged port, or to set the privileged port number
to a value less than 1500, usually to 1024.
1.4.21 POSIX Subsystem
Oracle Database 11g Release 2 requires the POSIX subsystem and access to the POSIX
file system. The following exceptions may occur:
■ Ask the BS2000 administrator to increase the number of UFS devices (parameter
NOSTTY in SYSSSI.POSIX-BC . version ), if you get the following message:
CCM0090: ALL UFS TERMINAL DEVICES ARE IN USE OR PERMISSION DENIED
■ The termination of the POSIX subsystem also terminates the Oracle instance.
