Mark, When you write code, you have to write to and link to a given version of the API. That version has a specific set of calls, with specific parameters, with specific definitions. A different version of the API may have different calls and different parameters and different definitions.
When 7.5 was developed, we linked to the Oracle 10gR2 API (Well, if the compatibility matrix says that is the version that is it, I don't know otherwise myself). So, we are tied to that definition. Now, within the API, that api may be compatible (and it is) with many versions of Oracle. So, using that API, you can talk with Oracle 10g, 11g, and other versions as well. So, you can have any version of Oracle that is compatible with the 10gR2 API, but we do need the 10gR2 API installed as that is the interface we are using. The API is part of the Oracle client hence the version of the oracle client that must be installed. We don't have permission to redistribute Oracle binaries or libraries so we have to have you put them in place. Now, we just link to the Oracle libraries. IF there is a later version (or earlier version) that has EVERY call we need to make, the exact same parameters as the ones we expect with the exact same definition and same limits and same everything else and the same name for every procedure that is called, then in theory everything would work. But, we cannot gaurantee that. We KNOW that we work against the definition of the client in 10gR2 as that is what we link and test with. You may get odd and suprising errors using another version of the client. Since you can have this version of the client for any Oracle installation of 10g or later, it is simply safest to have that specific client installed or best compatibility and least chance of oddity. BMC supports things tied to that version of the client and does not gaurantee what may work or not with any other version of the client. Really, this is no different from if you have a 7.6.3 mid-tier, you need 7.6.3 API libraries installed with the mid-tier. This is regardless of whether the mid-tier is talking with a 7.6.3, 7.5, 6.3, 9.4, or whatever version of the AR System server. I hope this helps, Doug Mueller ________________________________ From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] On Behalf Of Brittain, Mark Sent: Tuesday, January 25, 2011 12:44 PM To: arslist@ARSLIST.ORG Subject: Oracle Client Question ** Hi All I am building a 7.5 server on Linux with Oracle 11g. The compatibility matrix states that only the Oracle 10gR2 client can be used. None higher or lower. Is that true? This does not make sense to my DBA and I don't have a good explanation for him. Anyone know why this is? Has anyone successfully used the 11g client with the 11g server?
