GoldenGate - cannot open shared object file

While login into Goldengate command line interface we faced below error. Resolution or error is not that much complicated but many time we are not able to find out what can be the issue while working in under pressure situation so thought to write this piece.

[oracle@ggtest ogg]$ ./ggsci
./ggsci: error while loading shared libraries: cannot open shared object file: No such file or directory

Only need to export library from oracle home to resolve this error. It is better to append this in .bash_profile of Oracle user.

[oracle@ggtest ogg]$ export LD_LIBRARY_PATH=$ORACLE_HOME/lib
[oracle@ggtest ogg]$ ./ggsci

Comparison between Exadata X4-2 and X5-2

Obliviously ED X5 would be faster and flexible compare to earlier version of ED. Here we have given comparison between X5 and X4 full configuration ED rack based on datasheet provided by Oracle.

Now from X5-2 Oracle introduced Oracle Virtual Machine to do the virtualization on ED machine, if there is any requirement of hard limits on CPUs and memory or required independent OS/Admin than we can use this virtualization feature.

There is no licence cost for OVM , it's free of cost with ED X5-2.

From ED X5-2 High performance disk has been replaced with Extream Flash (EF).
