UNIX Kernel Parameters
Review the UNIX kernel parameter settings.
• If upgrading from Ingres 6.4, you may have to increase the size of a shared memory segment because Ingres builds a larger shared memory segment for locking and logging than it did in Ingres 6.4.
• If upgrading from a more recent version of Ingres, you may not have to change kernel parameters.
A 100 MB shared memory segment will accommodate most installations. Each platform modifies the shared memory limits in its own way, so read the platform-specific information in the Readme file. You may need to involve the system administrator.
It is a sensible practice to configure the new development installation in a similar way to the production installation.
