Shared memory on Solaris?

SQL*Plus reports that the package STANDARD is not accessible. It seems that the Oracle server is unable to allocate enough shared memory to create the STANDARD package.

System Configuration:
SunOS 5.5.1
Oracle7 Server Release 7.3.2.1.0
Sun SparcStation 5 with 32 MB main memory, 200 MB swap file

The gory details:
On logging on to SQL*Plus as 'system', the following error message appears:

ERROR:
ORA-06553: PLS-213: package STANDARD not accessible

Ran standard.sql. Did get ORA-04031: unable to allocate 4096 bytes of shared memory ("unknown object","PL/SQL MPCODE","BAMIMA: Bam Buffer")

I've been playing with shared_pool_size in init<db>.ora and SHMAX in /etc/system to try to get more shared memory.

Does anyone have any ideas?
