在Oracle中部署plsql软件包

Question

I'm looking to learn about possible ways of deploying large number of plsql packages as dependencies seem to be quite a problem. As it works now, packages are being deployed in several iterations redeploying em again if they couldn't be deployed in previous pass due to missing dependency. I hope to hear about different approaches to the problem and will update my question if u happend to havequestions for me to make it more clear.

Would it even be ok to search guidance this way on SO?

Answer 1

I would recommend to install all specs first in proper order. Then install all bodies. All dependencies need to be predefined once in master install script.

Update: What else you can do is:

1) load all package specs into main list (I assume all specs and bodies are stored separately. if not then it need to be done)

2) loop all specs from the main list.

3) try to compile it. Add to failed list if it fails.

4) When reach to the end of main list replace all items from it with items from failed list.

5) Go to step 2.

At the same time you can save results of the first run and second run could order items according to results of previous call. This will minimize number of iterations.

Bodies could be installed in any order...

However you need to keep in mind dependencies on the views and from the views - specs could depend on views (view_name%TYPE, cursors and etc) and views depends on package specs (could call package functions). This is not trivial problem... Can you explain how it is solved currently please?

Answer 2

I myself just install all the procedural code (in any order) and later (re)compile all invalid objects.

There are several way to recompile all invalid objects:

• UTL_RECOMP
• DBMS_UTILITY.COMPILE_SCHEMA
• Manually like Tom Kyte suggest and I use
