Hi Gaurav and all,
Issue is resolved
Some event parameters were added in spfile with command ALTER SYSTEM SET EVENT = '10027','10028','10142','10183','10191','38068 ,level 100','38085','38087','44951 ,level 1024','10995 ,level 2' scope = SPFILE;
This command had syntax errors in it and thus the problem had occurred
Copying the entire string from our Production server did not help nor did the manual editing of spfile (/oracle/SID/112_64/dbs/spfileSID.ora
Finally pfile from (/oracle/SID/112_64/dbs/initSID.ora) was edited and the event parameters which were shown in the error were removed. Then the DB was brought up with command
STARTUP pfile = /oracle/SID/112_64/dbs/initSID.ora
Once the DB opened, spfile was created from pfile by command
create spfile from pfile
Then once again the DB was bounced with
shutdown immediate
startup
Once the DB started, once again the missing parameters were added with ALTER SYSTEM SET EVENT command.
Then once again the DB was bounced with
shutdown immediate
startup
Thanks all
