Notes on installing Oracle 11g on Linux RHEL6

The Oracle 11g database is installed on RHEL6, and several problems occur on the way. The record is as follows:

1. the kernel settings provided in many documents are based on their memory. You should first know the role of these kernel settings before making changes according to their settings. The online version is basically for 2G and m

2. environment variables. Remember to add the binm directory under the oracle directory to the PATH variable of. bash_profile.

3. OUI10035 error. The oraInventory directory is at the same level as ORACLE _, that is, if ORACLE_BASE is under/, the oraInventory directory is also under, if ORACLE_BASE is in/usr, oraInventory is in/usr. Note the following when creating directories and granting permissions

4. Error in invoking target 'agent nmb nmo nmhs 'of makefile ins_emagent.mk. From some solutions on the internet, I feel like ORACLE is temporarily insufficient to support RHEL6. I ignored it directly. Click to continue the installation.

5, OUI-25031, this gold error also encountered... It's really strange. Whether the network is disconnected or not .. You can skip this operation on itpub.

6. Install oracle and then create an oracle database. After installation, you may find that the Listener (Listener) may not be started. I started it by using netca reconfiguration...

Successfully installed, tested table creation, and inserted data ~

It seems that the previous errors can be skipped.

But I don't know if this will affect the cluster. After all, I only have a single node.

Well ..

Sysresv error detected today: libclntsh. so.11 not found

So next time, remember to set the LD_LIBRARY_PATH variable in. bash_profile .. Specifically, it is set that there is a lib folder in the oracle installation directory. Set it here.
