1/ install software
2/ create database and listener (-emconfiguration NONE)
3/ setup emca

Parts one and two are working like clockwork. Part three–not so much.

So, first I need to remove sysman, or emca crashes out. Is this bad or good? I dunno…found some code that does this.

Then unlocked DBSNMP and set password (also not documented) since I saw errors relating to this in early attempts.

Knocked together a script by a little guesswork and mostly piecing together things from the net:
emca -config dbcontrol db -repos create -silent -SID oracle1 -PORT 1521 -ORACLE_HOME /u01/app/oracle -ORACLE_HOSTNAME prd-db-1 -DBSNMP_PWD dbsnmp -SYSMAN_PWD sysman -SYS_PWD ora123

emca likes this well enough, and completes..

INFO: Repository successfully created

however…
emdb.nohup:
The agentTZRegion value in /u01/app/oracle/ltxe-
nabb-prd-db-1_nabbprdexp1/sysman/config/emd.properties is not in agreement with

TZ setting has not changed since the last start of the agent.

After a good chunk of my life is wasted, get this:
SEVERE: Error starting Database Control

These are all issues I’m finding in hundreds of posts and everyone seems to be guessing what the cause is. I’ve seen some references to TZ issues and have three observations on that:
1/ TZ is set correctly in oracle’s environment and Australia/Victoria is supposedly a supported value
2/ Oracle thinks this timezone is GMT+11, which is wrong. It’s +10 except during EDT. Larry needs to check his homework more carefully.
3/ WTF? If the TZ doesn’t work out, fall back to a default. Since when is this a critical error? What boneheads code this stuff?

The really infuriating bit is that with the interactive dbca option at initial install time, runInstaller sets up EM just fine, but I cannot find this code path!

One more observation: having EM log its problems in eight(?) different locations does not strike me as best practice.

Yes I am really pissed off with this!

If anyone knows the incantation to get EM working reliably without the dbca GUI, I’d dearly like to know. I’ve tried emca command line and interactive, dbca at the create database stage, dbca -configureDatabase after it’s built, nothing works. It just won’t start. It’s driving me nuts.
