ASM cannot be used until Oracle CSS service is started on AIX

Environment : oracle10gR2 on AIX5.3

Problem : When i run the script localconfig add from command prompt on $ORACLE_HOME/bin path as root user to configure and start CSS
# id
uid=0(root) gid=0(root)
#./$ORACLE_HOME/bin/localconfig add

Solution: Install the below Apar’s
xlC.aix50.rte:7.0.0.4
xlC.rte:7.0.0.1
rsct.basic.rte
rsct.compat.clients.rte
rsct.basic.rte
rsct.compat.clients.rte
and run again same command or
#./$ORACLE_HOME/bin/localconfig reset

Note: TO configure ASM Cluser Synchronization Service(CSS) must be configured and started.

How to Drop Database in Oracle 10g?

connect to database as sysdba user
$sqlplus /nolog

SQL>conn sys/@connectionstring as sysdba
Ex: SQL>conn sys/sys123@oradb as sysdba

SQL> shutdown immediate;
oracle database closed
oracle database dismounted
oracle instance shutdown

Start the database to restrict mode
SQL> startup restrict mount;
or
SQL>startup mount exclusive restrict;

Confirm the database name before dropping.
SQL> select name from v$database;
NAME
---------
ORADB

SQL> drop database;
Database dropped

Just check the alertlog file what are the files deleted.

This will drop only database physical files not trace file parameter files.

Solution: So try execute
# rpm -qa grep libgcc
# rpm -qa --queryformat "%{NAME}-%{VERSION}.%{RELEASE} (%{ARCH})\n" grep libgcc
Output should be below version and above it
libgcc-3.4.6.9 (i386)

Solved by installing rpm libaio-0.3.103-3.x86_64.rpm
Try to apply using force option as
#rpm –Uvh - - force
Check the version of rpm installed by using the below view
# rpm -qa --qf '%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH}\n' grep libaio

Segmentation fault when connect to sqlplus

Problem : Segmentation fault when connect to sqlplus
Solution
It seems there is a linking problem for sqlplus which causes dbca to fail while creating repository database.Follow the below action plan.Ensure libgcc 3.4.6 for i386 and x86_64 architectures are installed. Then,
cd /usr/bin (as root)2. mv gcc gcc.script3. mv g++ g++.script4. ln -s gcc32 gcc5. ln -s g++32 g++6. login as oracle software owner (make sure environment is correct)7. cd $ORACLE_HOME/bin (The db10g ORACLE_HOME)8. relink all9. cd /opt/oracle/product/db10g/bin./sqlplus
Now the problem is solved.

Gzip of the file is failing to do zip.

Problem: Gzip of the file is failing to do zip.
Solution: Type the command which zip

PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/local/bin:/etc; export PATH
Now gzip is working fine.

solution 1.
SQL> conn sys/sys123@orat32 as sysdba
ERROR:
ORA-01031: insufficient privileges

Change home directory of OS user

Go to the path and create a directory(where i need) with new name and move the contents from old directory to new directory if any and do as below.
Vi /etc/passwd
Rename the old home to new home directory
Ex I need to change from /export/vol01 to /export/vol02
Earlier
oraguest:x:176:117::/export/vol01/home/oraguest:/bin/ksh
#later chage to
oraguest:x:176:117::/export/vol02/home/oraguest:/bin/ksh
and save it
