Oracle 11gR2 installation failed due to error in invoking target ‘irman ioracle’ of makefile bms.mk

I had ensured all oracle packages were installed properly prior to starting installation & oracle installer did not give any warning in prerequisites check.

so i ensure swap memory is sufficient or not, In my case swap space utmost consumed, so after increasing swap space setup has been started successfully.

Steps to increase swap size:

[root@centos ~]# free -m
total used free shared buffers cached
Mem: 483 475 7 0 1 283
-/+ buffers/cache: 190 292
Swap: 511 242 269

[root@centos ~]# dd if=/dev/zero of=/swapfile11 bs=1024 count=2097152
2097152+0 records in
2097152+0 records out
2147483648 bytes (2.1 GB) copied, 44.022 s, 48.8 MB/s

[root@centos ~]# mkswap /swapfile11
Setting up swapspace version 1, size = 2097148 KiB
no label, UUID=4d6e7614-0d03-43ce-b699-0d7f85ef313f

[root@centos ~]# swapon /swapfile11

[root@centos ~]# free -m
total used free shared buffers cached
Mem: 483 476 7 0 1 281
-/+ buffers/cache: 192 290
Swap: 2559 242 2317

If you want to make this change persistent for future then make the following changes in ‘/etc/fstab’ file.

[root@centos ~]# vi /etc/fstab
/swapfile11 swap swap defaults 0 0

[root@centos ~]# free -m
total used free shared buffers cached
Mem: 483 419 63 0 3 222
-/+ buffers/cache: 193 289
Swap: 2559 114 2445

Swap size increased with 2 GB & Installation successful.
