Oracle 10gR2 on Solaris 10 - Zoned Machine getting ORA-27102 Errors

Question

Getting Memory issues in Solaris 10. I have configured the database to have only 2GB of SGA, but still getting ORA-27102 and also when we look at top command it seems all the memory is not available. The machine is divided into two zones, machine has 32 GB memory and has 8 processors. The shared memory settings I have done is 8 GB max.
Any help in this regard would be helpful. Is anything special needs to be done in zones ?
Thanks,

Answer 1

There is no trace files to look at . Alert log does not have entry and bdump & udump does not have any trace file.
I was more interested to know, if somebody has installed Oracle 10 on Solaris 10 with a zone or container in solaris. What parameter settings was done on unix setting was it only shared-memory defined, if anybody has come accross memory issues in the machine after installing Oracle 10 with Solaris 10, and the machine has been zoned in two or more zones.
