35.3. Patching Oracle Intelligent Agent on Red Hat Enterprise Linux 3
When you run "
agentctl start" (Oracle 9.2.0.4), dbsnmp will crash:
$ su - oracle $ agentctl start DBSNMP for Linux: Version 9.2.0.4.0 - Production on 07-JAN-2004 19:11:14 Copyright (c) 2003 Oracle Corporation. All rights reserved. Starting Oracle Intelligent Agent.../u01/app/oracle/product/9.2.0/bin/dbsnmpwd: line 156: 1855 Segmentation fault nohup $ORACLE_HOME/bin/dbsnmp $* >>$DBSNMP_WDLOGFILE 2>&1 /u01/app/oracle/product/9.2.0/bin/dbsnmpwd: line 156: 1868 Segmentation fault nohup $ORACLE_HOME/bin/dbsnmp $* >>$DBSNMP_WDLOGFILE 2>&1 /u01/app/oracle/product/9.2.0/bin/dbsnmpwd: line 156: 1880 Segmentation fault nohup $ORACLE_HOME/bin/dbsnmp $* >>$DBSNMP_WDLOGFILE 2>&1 /u01/app/oracle/product/9.2.0/bin/dbsnmpwd: line 156: 1892 Segmentation fault nohup $ORACLE_HOME/bin/dbsnmp $* >>$DBSNMP_WDLOGFILE 2>&1
To resolve this problem, apply the patch
p3238244_9204_LINUX.zip from http://metalink.oracle.com, search for 3238244 to see the bug and patch information.
Before you apply the patch, make sure the instance is down!
Make sure the
opatch script appears in your $PATH. To verify if opatch is in your $PATH, run the following commands:
$ su - oracle $ which opatch /tmp/OPatch/opatch $
Please note, the patch needs "
fuser" which should be located in /sbin, if it is not you will need to install it. To apply now the patch, run:
$ su - oracle $ unzip p3238244_9204_LINUX.zip $ cd 3238244 $ export PATH=$PATH:/sbin $ opatch apply
Now you need to relink
dbsnmp. This is the binary that crashed when running agentctl start. To find which makefile handles the linking of dbsnmp, you can run:
$ su - oracle $ find $ORACLE_HOME -name "*.mk" | xargs grep -l dbsnmp /u01/app/oracle/product/9.2.0/network/lib/ins_oemagent.mk /u01/app/oracle/product/9.2.0/network/lib/env_oemagent.mk $
To relink
dbsnmp and all associated executable files which are maintained by the ins_oemagent.mk makefile, run:
$ su - oracle $ cd $ORACLE_HOME/network/lib $ make -f ins_oemagent.mk install
Now you should be able to start the agent:
$ su - oracle $ agentctl start
Note
Do not forget to undo the links to
/usr/bin/gcc and /usr/bin/g++ if you do not need them any more. You may also want to undo the changes in /etc/ld.so.preload file.
