Do I need the BI-file?

[andersb]

Hello,

we have an IBM with AIX 5.2 with Progress 9.1D.
When it came to us Progress, was already installed, and was up and running.
The database was installed
But there is no BI-file.
All i have is these files:

PA.db
PA.b1
PA.d1
PA.df
PA.lg
PA.lic
PA.lk
PA.st

So I wonder, is'nt the BI-file mandatory in Progress 9?

Anders,

The PA.b1 file is the bi file, and you DO need it.

HTH,

Brad.

Single-volume database store before-image in: (eg.) mydb.bi

Multi-volume databases store the bi file in the following form:
mydb.bi becomes mydb.b1...mydb.bn for each extent n

Since v9, all databases are multi-volume.

No, Lee. You can configure a single-volume db on V9 as well. Don't know why anyone will doing this...but I have seen DBA configure it on a single-volume...

As long as your last mydb.bn is not a fixed extent...then your db should be fine...

I think you're confusing single-extent with single-volume. All v9 and later databases are multi-volume and have storage areas. Each storage area can have one or more extents (except for after image areas which are wierd -- each ai area has exactly one extent or each extent is an area depending on how you want to look at it...)

Prior to v9 "multi-volume" referred to whether or not you used a structure file.

Post v9 there is no choice. All databases use structure files. In order to use conv89 you must first convert a v8 database to multi-volume.
