OpenEdge 10.2B迁移：Solaris 10转11的编译与数据库操作问询

Great question—let’s break this down clearly since you’re juggling both an OS upgrade and an OpenEdge minor version jump for your application.

1. Do you need to recompile all programs? #

Yes, you absolutely need to recompile all your OpenEdge source files (.p, .w, etc.) in the new environment. Here’s why:

• OpenEdge compiled runtime files (.r) are tightly tied to both the specific OpenEdge version and the underlying OS platform. The .r files you generated on Solaris 10 with OpenEdge 10.1c will not be compatible with Solaris 11’s system libraries or the OpenEdge 10.2B runtime—attempting to run them will likely throw errors or crash.
• Even within the OpenEdge 10.x family, 10.2B introduced minor changes to runtime behavior and API signatures. Recompiling ensures your code adapts to these changes and avoids subtle compatibility bugs.
• Don’t forget third-party components or custom extensions (like .so shared objects for Solaris)—these also need to be recompiled or rebuilt for Solaris 11 and OpenEdge 10.2B.

Pro tip: Start with a small set of critical programs first to test for any unexpected syntax or API issues before compiling your entire codebase.

2. Should you use dump & load instead of database refresh? #

Yes, dump & load is the recommended approach here, rather than a direct database refresh (like using procopy or restoring a filesystem-level backup). Here’s the rationale:

• While OpenEdge 10.1c and 10.2B are in the same major version line, 10.2B includes minor updates to database storage formats and index structures. A direct file copy (refresh) might carry over incompatible metadata or corrupt data pages, especially when moving across Solaris versions (which have differences in file system handling and kernel-level I/O).
• Dump & load exports your database schema and data using OpenEdge’s proutil or dump utilities, then reimports them into a fresh 10.2B database on Solaris 11. This process automatically cleans up database fragmentation, validates data integrity, and ensures all objects are aligned with the new OpenEdge version’s requirements.
• A direct refresh might work for identical OS and minor version jumps, but the combination of Solaris 10→11 and OpenEdge 10.1c→10.2B makes dump & load the far safer choice to avoid post-migration outages or data corruption.

Pro tip: Always test the dump & load process in a staging environment first, and verify all data, indexes, and application functionality before executing it in production.
