Datapump & max roles exceeded

Question

So, I was trying to export a schema out of a newly installed 10.1.0.4 instance, something I've done repeatedly in a 10.1.0.3 instance, using the following parmfile
[oracle@linux-test transport]$ more expdp_audits.par
SCHEMAS=audits
LOGFILE=expdpdvlp_audits.log
DUMPFILE=expdpdvlp_audits.dmp
DIRECTORY=dpump_dir_nasand I get this error
[oracle@linux-test transport]$ expdp forbesc@dvlp parfile=expdp_audits.par

ORA-28031: maximum of 148 enabled roles exceededI'm able to log into SQL*Plus, and I was able to perform an exp, but expdp is unhappy. There's no way I'm actually exceeding this number of roles

Answer 1

TEST> select name, value, issys_modifiable from v$parameter where name = 'max_enabled_roles';
NAME                      VALUE      ISSYS_MOD
max_enabled_roles         150        FALSEAs ISSYS_MODIFIABLE is false, you can't change the value dynamically. You must use a SPFILE scope and then bounce the instance:
ALTER SYSTEM SET max_enabled_roles=100 SCOPE=SPFILE;
SHUTDOWN IMMEDIATE
STARTUP
tell me the steps by which I can get my database into MOUNT stage to do this activity?Yopu don't need the instance to be in MOUNT mode to perform this. You just have to bounce it.
