Symptoms
In environment where listener home (including SCAN listener which resides in Grid Infrastructure/ASM home) and database home are owned by different OS user, ORA-12537 could happen when connecting through listener, when creating database through DBCA, or when installing database software and creating a database in runInstaller. Job Role Separation is a typical example as SCAN and local grid home listener is owned differently than database.
- Error detail
12537, 00000, "TNS:connection closed"
// *Cause: "End of file" condition has been reached; partner has disconnected.
// *Action: None needed; this is an information message.
Before the error is reported, connection could hang for a while, and a core file may also be generated.
- Screen output:
SQL> conn system/xxx@OSES

SEVERE: [FATAL] [INS-30502] No ASM disk group found.
CAUSE: There were no disk groups managed by the ASM instance +ASM1.
Cause
1. Listener owner (including SCAN listener) can not access oracle binary in database home:
As listener owner:
$ ls -l $RDBMS_HOME/bin/oracle
ls: /home/oracle/app/oracle/product/11.2/db/bin/oracle:
Permission denied
2. Oracle binary in database home has wrong permission:
ls -l $RDBMS_HOME/bin/oracle
-rwxr-x--x 1 oracle asmadmin 184286251 Aug 9 16:25 /home/oracle/app/oracle/product/11.2/db/bin/oracle
The permission "
-rwxr-x--x" is wrong as it's missing suid bit, oracle binary should have permission of 6751:
-rwsr-s--x 1 oracle asmadmin 184286251 Aug 9 16:25 /home/oracle/app/oracle/product/11.2/db/bin/oracle
Note: If Job Role Separation is in place, the group will be <asmadmin>, otherwise it will be <oinstall>
3. File System for database home does not support setuid/suid or has nosetuid/nosuid set:
mount| grep <mount_point_of_ORACLE_HOME>
/home/oracle on /dev/dsk/diskoracle read/write/nosuid..
Solution
Solution is to make sure file system for database home has setuid/suid set, database binary($RDBMS_HOME/bin/oracle) has correct ownership and permission, and listener owner is able to access database oracle binary (as listener owner, "ls -l $RDBMS_HOME/bin/oracle" will tell)
If its Job Role Separation environment, please refer to the following document:
