Last week I was working on WebLogic Server where Admin Server failed to start because Disk was 100% full. Admin Server failed to start after clearing some unwanted files from server with below error message
Error message in Admin Server log file $DOMAIN_HOME/servers/AdminServer/logs/AdminServer.log

Since error was point to embedded LDAP server for weblogic so I compared files related to embedded ldap server ($DOMAIN_HOME/ servers/ AdminServer/ data/ ldap/) with one of our running weblogic instance and found that size of replicas.prop file was 0 byte.
$DOMAIN_HOME/servers/AdminServer/data/ldap/conf
-rw-r—– 1 oraowc dba 568 Aug 13 09:17 vde.prop
-rw-r—– 1 oraowc dba 0 Aug 13 09:17 mapping.cfg
-rw-r—– 1 oraowc dba 0 Aug 13 14:33 replicas.prop
.
Fix:
Option 1 - Open
$DOMAIN_HOME/servers/AdminServer/data/ldap/conf/replicas.prop and add line
replica.num=0
or
Option 2- Move file $DOMAIN_HOME/servers/AdminServer/data/ldap/conf/replicas.prop to replicas.prop.bak (On Restart WebLogic Server will recreate this file)

can say how to run managed server…i am using weblogic 10.3.3. and oim 11g
i am getting authentication failure while starting managed server where as weblogic is starting normally
@ Mohan,
1. Did it ever work in past ?
2. Did you configure OIM server by running condfig.sh (first time)
If you have boot.properties in $DOMAIN_HOME/servers/oim_server1/security then remove it and then start it using
$$DOMAIN_HOME/bin/startManagedServer.sh oim_server1 http://weblogicservername:7001
enter username and password when prompted
Thanks you. I change these file and my weblogic start fine, good, my server not start because Disk was 100% full, and it created the empty file.
where can i download OAM 10.1.4.1.0.1
Hi..Atul Kumar
I have installed OAM 10.1.4.0.1 with AD now i want to upgrade to OAM 10.1.4.0.4 can u please provide me the doccument to upgade
@ Mohankumar,
Please leave comment under correct post (You can do this under any OAM post where as this is weblogic post)
Why are you installing OAM 10.1.4.0.1 when latest in 10g is 10.1.4.3 and in 11g its 11.1.1.3 (why not to install 10.1.4.3 directly)
HI..
while installing oam Oracle Access Manager 10.1.4.0.1 Identity Server
i am getting following error…
i am installing on ubuntu 10.10 can you please provide solution thank you
The product that you are about to install needs to be owned by a dedicated
user. Only root or the dedicated user may be able to start the service. Most
of the time the server is run as `root’ or `nobody’.
Enter the username the Identity server is running as [nobody] oamuser
Enter the Group for the above username [nobody] oamuser
Press 1 for Next, 2 for Previous, 3 to Cancel or 4 to Redisplay [1] 1
Sorry, invalid user `oamuser’ or invalid group `oamuser’.
Please check and enter again.
Hi Atul Kumar,
Thanks for your post, it was very helpfull !!
