Due to the fact that It was installed with the kernel 2.x included in the RedHat 7.0 distribution, we have realized that the system only recognizes 1 Gb of RAM. The problem is that we would need to recognize that remaining 1 Gb without a complete reinstallation of the system. The main issue is to reinstall Oracle. The current version of Oracle (8.1.7) doesnt seems to work with kernels 2.4.x. If it should work, please let me know how I could upgrade the kernel without upgrading to Oracle 9i (that seems to be the issue, only Oracle 9i supports kernels 2.4.x), because we dont have time to plan a migration to 9i. We have looked around in some web sites, and seems that there is the workaround of adding in the /etc/lilo.conf an entry saying: "append=960M", but we are not sure if that would work for 2048M. Which would be the solution? To recompile the kernel? Is it possible to recognize in a kernel 2.x to recognize more than 1Gb of RAM? many thanks in advance Miguel
