Oracle: ORA-01078 and LRM-00109 Error

After the database is installed today, after the database is created through dbca, the time to start and close the database through sqlplus has consistently reported the following error such as: SQLgt; startupORA-010

After the database is installed today, after the database is created through dbca, the time to start and shut down the database through sqlplus has consistently reported the following error, such as: SQLgt; startup ORA-010

Environment Description:
Operating System: RedHat 5.3 64bit
Oracle version: 10.2.0.1 SID: search6

After the database is installed today, after you create a database through dbca, the following error is reported during the time when you start and close the database through sqlplus:
SQL> startup
ORA-01078: failure in processing system parameters
LRM-00109: cocould not open parameter file '/app/soft/ora10g/product/10.2.0/db_1/dbs/initsearch. ora'
···
SQL> shutdown immediate
A ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux-x86_64 Error: 2: No such file or directory

At the beginning, no problem was found in alert. log, and the database was logged on normally. After a long query, no problem was found. Later I suddenly remembered that the configuration document in. bash_profile was copied directly from the previous configuration document, which may be due to a problem in this configuration. This is true. bash_profile wrote the SID wrong.
[Oracle @ szmlvm29-54 ~] $ Cat. bash_profile
#. Bash_profile
······
Export ORACLE_SID = search # the correct one is search6
······

So, when you encounter this problem again later, you also need to check whether the SID of the configuration document is accurate.
