Oracle FMW GoldenGate Veridata setup OUI troubles with X Server

I have spent several hours finding the reason why installation of Oracle GoldenGate Veridata 12.2.1 on RedHad Enterpise Linux 7.3 starts correctly on one machine and doesn’t start on another – the same version and installed by the same administrator.

Starting installation just complains on X Server setup:

java -jar fmw_12.2.1.2.0_ogg.jar
...
Preparing to launch the Oracle Universal Installer from /tmp/OraInstall2017-03-30_10-47-55AM
Log: /tmp/OraInstall2017-03-30_10-47-55AM/install2017-03-30_10-47-55AM.log
X-Server access is denied on host
[Fatal Error] DISPLAY variable set incorrectly: localhost:11.0
[Resolution] Verify that your DISPLAY environment variable is set correctly, 
and that there is an X11 server on the system. If you are 
running the Oracle Installer as a different user or on a different host, 
you may need to use the xhost command to ensure that host/user 
has permission to write to your display

The most interesting thing is that starting already installed 11.2.0.4 GUI utils, like NETCA/DBCA/DBUA, works correctly… and they use the same X Server setup, actually through X Server Forwarding… because of this I have DISPLAY=localhost:11.0 Continue reading

Starting MRP reboots Linux Server (once more)

I have already blogged on similar issue, but decided to do it once again because symptoms are the same, but the source reason is different.

So, one of our customers asked for our help in situation when Linux server rebooted by them-self and, because it was hosting standby database, it was quite urgent to get it working properly to provide protection for primary database.

I have just started managed recovery process and everything was OK for a couple of minutes, but then … console hang and server just went down for reboot… interesting 😉

Just to test if it’s consistent, I have done it once more and… it rebooted once again after applying several archive logs… 😉 Continue reading

Strange multiple Oracle(CRS and other) processes and Linux Threads

Once we have been contacted by one customer with very strange problem:

“On one node of our two node RAC cluster on RHEL 4.5 we have quite strange behavior – multiple oracle CRS processes and as a result we are unable to stop CRS using crsctl stop crs… – we have to reboot node…”

It was quite interesting situation from next point of view:

The same issue was mentioned without resolution 5 years ago on forums.oracle.com – Thread: Multiple “crsd.bin reboot” at once
