Oracle 11g Installation Problems and Solutions

The main problems are:

1. After the system parameters are set, the data set in the condition detection process during database installation is completely different from that detected by the installer, especially the semmax value. Originally, it was set to the same according to the system detection value, but the result was followed by two zeros. This setting should not affect installation.

2. The database software is installed normally. ORA-27102: out of memory appears during database configuration. The cause of this error is that the size of the SWAp partition is insufficient and you need to increase the partition size. Use the following method to temporarily increase the size of the swap partition so that the installation process is normal:

$ Su root // The logon permission is root.

# Mkdir 4096 M/file. swap // you can set the size according to the swap partition detected by the system during oracle installation.

# Swap-a/file. swap // Add a swap space

# Swap-l // view swap space

By increasing the swap partition size in this way, you can complete the oracle installation. The database configuration can also be completed normally.

However, this method can only temporarily increase the size of the swap partition. When the machine restarts, this part of the swap space will be automatically released. It is better to divide a piece of space into swap partitions.
