ORA-27123: unable to attach to shared memory segment
669300Nov 7 2008 — edited Nov 10 2008Hi,
I've installed Oracle 10g XE on Ubuntu 8.10. I am now installing an application (Remedy ARS 7) that tests connectivity to the database during installation. In response to this test I get the following stream of errors:
Cannot open catalog; Message number = 550 (ARERR 550)
ORA-01034: ORACLE not available
ORA-27123: unable to attach to shared memory segment
Linux Error: 13: Permission denied
ORA-01034: ORACLE not available
ORA-27123: unable to attach to shared memory segment
Linux Error: 13: Permission denied
ERROR: Cannot open the database ... exiting
The database is up and running and I can connect using SQLPlus using the same username/password that the installer is testing with. I've looked at the SGA settings and they are:
Allocation (MB)
Shared Pool 148
Buffer Cache 408
Other 20
Total 576
The connection is tested with a program called "oraload". When I run it at the command line I get the following error:
./oraload: error while loading shared libraries: libicuucbmc.so.32: cannot open shared object file: No such file or directory
This is a symbolic link (with permissions 777) to a file with 644 and they reside in the same directory as oraload.
Does anyone have any suggestions?
