OpenJDK JVM not supported while installing Oracle Fusion Middleware on Linux 7

Leave a comment

Various software releases will sometimes have incompatibility because the two products were released or tested at about the same time. This is the cause of Oracle Fusion Middleware 12.2.1.0.0 (FMW 12c) and
Oracle Enterprise Linux 7.2 (OEL 7). FMW 12c was thoroughly tested against OEL 6, but due to its release date collision with OEL 7, there are some validation which fail checks during the install. Resulting in the
error below:

[oracle@linux1 STAGE]$ java -Djava.io.tmpdir=/u04/tmp -jar fmw_12.2.1.1.0_infrastructure.jar -silent -ignoreSysPrereqs -responseFile /u01/STAGE/fmw.rsp
Launcher log file is /u04/tmp/OraInstall2017-07-13_08-41-06AM/launcher2017-07-13_08-41-06AM.log.

The OpenJDK JVM is not supported on this platform.
The log is located here: /u04/tmp/OraInstall2017-07-13_08-41-06AM/launcher2017-07-13_08-41-06AM.log.
[oracle@linux1 STAGE]$

This error is a result of FMW 12c being testing against OEL 6 with JDK 1.7, but the default JDK for OEL 7 is JDK 1.8. This article outlines a procedure to resolve this error and proceed with installation
of Oracle Fusion Middleware 12.2.1.0.0 on OEL 7 or any Linux 7 distribution.

1. Logon to OEL 7 server as the root user.

[root@linux1 ~]#

2. Determine current JAVA installed with command: java -version

[root@linux2 ~]# java -version
openjdk version “1.8.0_65”
OpenJDK Runtime Environment (build 1.8.0_65-b17)
OpenJDK 64-Bit Server VM (build 25.65-b01, mixed mode)
[root@linux2 ~]#

We will install an alternative JDK for use of FMW with one we know works, in this case that JDK is 1.7.0_79.

3. Move to a directory to install the alternative JDK. In this case we will use /opt with command: cd /opt

[root@linux2 ~]# cd /opt
[root@linux2 opt]#

4. Download the JDK 1.7.0_79 with wget command: wget –no-check-certificate –no-cookies –header “Cookie: oraclelicense=accept-securebackup-cookie” “http://download.oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.tar.gz” “http://download.oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-i586.tar.gz”

Resolving Oracle Error ORA-01653 by adding additional storage

Leave a comment

ERROR:
ORA-00604: error occurred at recursive SQL level 1
ORA-01653: unable to extend table SYS.AUD$ by 4096 in tablespace SYSTEM
ORA-02002: error while writing to audit trail
ORA-00604: error occurred at recursive SQL level 1
ORA-01653: unable to extend table SYS.AUD$ by 4096 in tablespace SYSTEM

1. Logon to the Oracle database as a sysdba user.

2. Validate that the system tablespace is out of space.

set pagesize 500
select a.tablespace_name,
(select sum(b.bytes)/1024/1024/1024 from dba_data_files b where a.tablespace_name=b.tablespace_name) as GB_TOT,
(select sum(c.bytes)/1024/1024/1024 from dba_free_space c where a.tablespace_name=c.tablespace_name) as GB_AVAIL,
100*(select sum(c.bytes) from dba_free_space c where a.tablespace_name=c.tablespace_name)/(select sum(b.bytes) from dba_data_files b where a.tablespace_name=b.tablespace_name) as PERC_FREE
from dba_tablespaces a where tablespace_name=’SYSTEM’;

TABLESPACE_NAME GB_TOT GB_AVAIL PERC_FREE
—————————— ———- ———- ———-
SYSTEM 10.27125 .01766357 .024375

SQL>

3. The query above showes that the system tablespace is out of space. The quickest fix is to add additional space to the SYSTEM tablespace, additionally we
can address the amount of data stored in the AUD$ tables referenced in the above error message. This alternative is address in another article.

4. To add additional space to the system tablespace, find the current location of SYSTEM data files on your system with the following statement.

SQL> select file_name, bytes/1024/1024 from dba_data_files where tablespace_name=’SYSTEM’;

FILE_NAME BYTES/1024/1024
——————————— —————

/u01/oradata/UCOP/SYSTEM01.DBF 10000

SQL>

5. Verify that you have enough space available on your drives and add an additional datafile;

alter tablespace SYSTEM add datafile ‘/u01/oradata/UCOP/SYSTEM02.DBF’ size 10000m;

SQL> alter tablespace SYSTEM add datafile ‘/u01/oradata/UCOP/SYSTEM02.DBF’ size 10000m;

Tablespace altered.

SQL>

6. Validate that you know have available free space in the SYSTEM tablespace and re-execute the statement which caused your initial error.

set pagesize 500
select a.tablespace_name,
(select sum(b.bytes)/1024/1024/1024 from dba_data_files b where a.tablespace_name=b.tablespace_name) as GB_TOT,
(select sum(c.bytes)/1024/1024/1024 from dba_free_space c where a.tablespace_name=c.tablespace_name) as GB_AVAIL,
100*(select sum(c.bytes) from dba_free_space c where a.tablespace_name=c.tablespace_name)/(select sum(b.bytes) from dba_data_files b where a.tablespace_name=b.tablespace_name) as PERC_FREE

RMAN utility produces error LFI-00005 and LFI-00004

Leave a comment

Error: During use of RMAN utility the following is generated.

RMAN-00554: initialization of internal recovery manager package failed
RMAN-03000: recovery manager compiler component initialization failed
RMAN-06001: error parsing job step library

LFI-00005: Free some memory failed in lfibrdt().
LFI-00004: Call to lfibgl() failed.
[oracle@mylinux1 bin]$

Check: Look at the storage configuration of both the RMAN binaries and location of backups. In this example the storage was OCFS, which can be used for both the backup pieces and the binaries, but not with the tag – datavolume.


/dev/mapper/oracle_home /rac1 ocfs2 _netdev,datavolume,nointr 0 0

1. Logon to the Oracle server as the root user.

2. Dismount the storage in question.

umount /rac1

3. Mount the storage without the datavolume tag.

mount /dev/mapper/oracle_home /rac1 ocfs2 _netdev,nointr 0 0

4. Update your /etc/fstab file with new entries.

This completes resolution of RMAN error due to use of OCFS storage.

Manually initializing Oracle OCFS2 stack

Leave a comment

Oracle provides the file system OCFS2 to support Oracle RAC file storage. This file system provides for a locking mechanism which allows files to be accessed by multiple Oracle instances while avoiding corruption. The OSFS2 file system binaries must be started before any OCFS2 formatted mount points can be accessed. This article shows the error generated when the OCFS2 stack has not been started and how to resolve the problem.

General OS error:


[root@mylinux /]# mount /dev/mapper/MPATH10 /u02
mount.ocfs2: Unable to access cluster service while trying initialize cluster

Resolution:

1. Logon to your server as root.
2. Execute the OS layer command /etc/init.d/o2cb enable

Listener Name incorrectly defined in lsnrctl

Listener Name incorrectly defined in lsnrctl

Normally, connection to an Oracle database is performed through the use of an Oracle listener, whose job it is to listen on a specific machine and port for request to connect to a one or more database instances. The listener is controlled by a utility named lsnrctl located under $ORACLE_HOME/bin no matter the OS. By default Oracle will name you listener process LISTENER on a standard Oracle installation. However, this is not a good practice due to security concerns. In this article we will discuss the error you will receive if you have a non-default Listener name and specify the incorrect name while attempting to start the process. This article was written using a window’s based install but will work just as well on UNIX and Linux.

1. Switch directories to your $ORACLE_HOME/bin directory.

cd C:\oracle\product\10.2.0\db_1\bin
C:\oracle\product\10.2.0\db_1\BIN>

2. Start your listener utility with the command lsnrctl.

C:\oracle\product\10.2.0\db_1\BIN>lsnrctl

Welcome to LSNRCTL, type “help” for information.

3. Believing that your listener’s name is listener attempt to startup the listener with the command start

LSNRCTL> start listener

TNS-01151: Missing listener name, listener, in LISTENER.ORA

Listener failed to start. See the error message(s) above…

LSNRCTL>

4. NOTE: the error message returned by lsnrctl states: that we are missing the listener name in the file listener.ora.

5. Navigate to the directory given for listener.ora file and view its contents. You will see that the actual name of the listener is listener_oracle not listener.

LISTENER_ORACLE =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.110)(PORT = 1521))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
)
)

SID_LIST_LISTENER_ORACLE =
(SID_LIST =
(SID_DESC =
(SID_NAME = orcl)
(ORACLE_HOME = C:\oracle\product\10.2.0\db_1)
)

(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
)

6. There is no reason to change the listener.ora file but only to give the correct listener name in the lsnrctl utilities start command. As shown below the listener startups correctly.

LSNRCTL> start listener_oracle

7. As shown above once we present the correct listener name, the listener starts without error.
