Problem: Startup database reports an error, content ORA-00205: Error in identifying control file, check Alert log for more Info

solution:

the first step: look at the journal CD $ORACLE_BASE/diag/RDBMS/zdzrac/zdzrac1/trace; Tail – 200 alert_zdzrac1. The log

note: 200 represents the display of 200 lines

CTL ‘,’/ disk2/ control01.ctl’, ‘/disk3/control03.ctl’,’/disk3/control03.ctl’ scope=spfile; Causes the control file path to change

step 3: find the path of the original control file on another normal node

SQL> select status,name from v$controlfile;

the STATUS of the NAME

——————————————————————————–

+ DATA/zdzrac controlfile/current. 256.947408805

step 4: modify the control file path in the spfilec parameter file to solve the problem

oracle# create pfile = ‘/ u01/app/oracle/product/11.2.0.4/dbhome_1/DBS/init0714 ora’ from spfile = ‘/ u01/app/oracle/product/11.2.0.4/dbhome_1/DBS/spfilezdzrac1 ora’;

*.db_domain=”

step 5: restart the database using the pfile file

startup pfile = ‘/ u01/app/oracle/product/11.2.0.4/dbhome_1/DBS/init0711 ora’;

step 6: create the spfile file with the modified pfile

SQL> The create spfile from pfile = ‘/ u01/app/oracle/product/11.2.0.4/dbhome_1/DBS/init0714 ora’ ‘;

step 7: close the database and start the database

SQL> shutdown immediate

SQL> startup
