DB2 running in a Linux enviornment
what are the PROS and CONS of running DB2 under Linux with the Linux running under z/VM as to running DB2 under z/VM without Linux.. Cliff Jackson Senior Systems Programmer 703-607-1393
Re: DB2 running in a Linux enviornment
Hi, Cliff. One of the pros for running DB2 on zLinux is that the version of DB2 for zLinux is under active development by the IBM DB2 group and supports more features and capabilities than does the DB2 for z/VM. I think the DB2 for z/VM is basically in maintenance mode only these days.

Re: DB2 running in a Linux enviornment
Cliff, We have about 15 z/Linux servers running db2 V9.5 and V9.7 servers between 4 and 6 GB of storage, using Luns and with No File System cache db2 option enable, with REORDER option off to this servers.. We have experiemented great performances. On Thu, Apr 21, 2011 at 12:32 PM, clifford jackson cliffordjackson...@msn.com wrote: Dave, what about storage capacity for large data bases and performance.

Re: DB2 running in a Linux enviornment
While I have no direct, hands on knowledge of DB2 on zLinux, I *can* state that Oracle runs very well in such an environment, and can serve out very large databases with very good to excellent performance. A bit of system's tuning is required, of course, but it's well worth the effort. Note that DB2 for z/VM runs in a CMS based environment, which is 31-bit, while the zLinux environment is 64-bit. I believe DB2 for zLinux is also 64-bit capable, allowing bigger databases in storage, etc. DJ On 04/21/2011 10:32 AM, clifford jackson wrote: Dave, what about storage capacity for large data bases and performance.

Re: DB2 running in a Linux enviornment
Optimal use of personnel Efficient overcommitment of resources Conservation of limited LPAR resource (even on the biggest boxes, you can only have so many) Network efficiency and redundancy Built in automation function (PROP) Rapid recovery using standard tools (ADRDSSU lets you put the whole environment back with the same tools you use for z/OS if you have it - cuts recovery time substantially) Simple production of security zones Need I continue?

Re: DB2 running in a Linux enviornment
Cliff, To add to this, the JDBC drivers for DB2 under z/VM are not being upgraded, either. This causes a problem with some 3rd party software connecting to the database.
