Adjustment oracle10G EM encountered several problems

Aug 13 posted in Oracle (RSS), 146 views.

For a long time did not update the blog, and a new environment for a lot of things have to re-start, ah, huh.

When I first came on it was not long called for a solution to the problem of oracle10G EM dbconsole. Was not used to em, though it is a good thing, but occupied by a host of resources for no reason is not very fond of.

Be familiar with the look and the emctl command emca. Emctl start dbconsole after the start with and found the system clock error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: haltImpl
at java.lang.Shutdown.halt (Shutdown.java: 184)
at java.lang.Shutdown.exit (Shutdown.java: 256)
at java.lang.Runtime.exit (Runtime.java: 123)
at java.lang.System.exit (System.java: 791)
at oracle.sysman.emSDK.conf.TargetInstaller.main (TargetInstaller.java: 4183)

The cycle of similar mistakes, unlike the em itself, a search which turns out to be a problem jdk autopilot oracle, why do not know. The system itself jdk (/ usr/java14) a direct link to the $ ORACLE_HOME / jdk, this issue is resolved, and then came new problems, the system error that EM can not find a directory, the directory format hostname_dbsid, and the implementation of emctl directory is always behind the run away with a big message:

ps: 0509-048 Flag-o was used with invalid list.
ps: Not a recognized flag: --
Usage: ps [-ANPaedfklmMZ] [-n namelist] [-F Format] [-o specifier [= header ],...]
[-p proclist] [-G |-g grouplist] [-t termlist] [-U |-u userlist] [-c classlist] [-T
pid] [-L pidlist]
Usage: ps [aceglnsuvwxU] [t tty] [processnumber]

This information is under aix a bug, oracle information is as follows:

Cause

In emctl.pl we have a command as below:
ps-p $ PID-o cmd - cols 1000 | grep DEMDROOT

In AIX platforms for some OS kernels, this command doesn't work. The correct command is:
ps-p $ PID-o args | grep DEMDROOT

Solution

If you get these errors while starting DBConsole, follow below action plan:

Follow below action plan.

a) Stop DBConsole - 'emctl stop dbconsole'
b) Take backup of 'emctl.pl' from $ ORACLE_HOME / bin
c) Edit emctl.pl and goto line number 1249, which is:
my $ ps = `ps-p $ PID-o cmd - cols 1000 | grep DEMDROOT`;
Modify above line as below:
my $ ps = `ps-p $ PID-o args | grep DEMDROOT`;
d) Save the file.
e) Start DBConsole - 'emctl start dbconsole' from $ ORACLE_HOME / bin

Was nothing we could do to find this deal, problem solving, followed by the directory does not exist is a problem. Check some information that this was the result after hostname change, probably to verify it, such is very high. Need to re-configure the em, so use the command:

emca-config dbcontrol db

Found the system to reform itself after the port has changed (it was 1158, it is now 5500), tried to change it back, was found to be occupied by 1158, does not matter anyway, and make on line 5500.

Em always found difficult to feel engaged, prompted a problem with too little information, do not like it.

Several documents attached to the back of the article, a closer look at the time.
