Solution to the problem that Oracle cannot start netmgr

Let's take a look at the demo: $ cat. bash_profile ...... # PATH $ PATH: $ HOMEbin # exportPATHORACLE_SIDltyORACLE_BASEu01

Let's take a look at the demo: $ cat. bash_profile... ... # PATH = $ PATH: $ HOME/bin # export PATH ORACLE_SID = ltyORACLE_BASE =/u01

See the following demo:
$ Cat. bash_profile
... ...
# PATH = $ PATH: $ HOME/bin

# Export PATH

Oracle_SID = lty
ORACLE_BASE =/u01
ORACLE_HOME =/u01/oracle
# PATH = $ ORACLE_HOME/bin: $ PATH
# LD_ASSUME_KERNEL = 2.4.19
LD_LIBRARY_PATH = $ ORACLE_HOME/lib:/usr/local/lib:/usr/X11R6/lib
TNS_ADMIN = $ ORACLE_HOME/network/admin
ORA_NLS33 = $ ORACLE_HOME/ocommon/nls/admin/data
ORACLE_OWNER = oracle
ORACLE_TERM = xterm
PATH =/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin: /usr/sbin:/usr/bin:/root/bin: $ ORACLE_HOME/bin
DISPLAY = 192.168.1.200: 0.0

Export ORACLE_SID ORACLE_BASE ORACLE_HOME PATH LD_LIBRARY_PATH TNS_ADMIN ORA_NLS33 ORACLE_OWNER ORACLE_TERM DISPLAY

$ Netmgr
... ...
Exception in thread "main" java. lang. verifyError: (class: oracle/net/mgr/servicename/DBPanel $1, method: actionreceivmed signature: (Ljava/awt/event/ActionEvent;) V) Illegal use of nonvirtual function call

Solution:
$ Vi ~ /Bin/netmgr
Row 139th: $ JRE-classpath $ CLASSPATH oracle.net. mgr. container. NetApplication oracle.net. mgr. container. NetApplication
Change to: $ JRE-classpath $ CLASSPATH-noverify oracle.net. mgr. container. NetApplication oracle.net. mgr. container. NetApplication
