Support for DB2 databases?

Just did some checking.

It seems that the primary site, in its original form on db2 v8 only used the 32k table spaces for the tables that were infact bigger than the 4k tablespace.

Admittedly I was a bit careless, as when I had created the 32k TS, I did not remove the default 4k tablespace from the database.

Since g2 does not specify the TS's on creation, everything makes sense now. I'll try to find a way to change the tablespace on those tables. Does g2, have an import export feature? As restoring a db2 backup doesn't allow me to change the tablespaces. And with the amount of tables and the presence of bit DATA, I'm not sure of the best ways to resolve this issue.

Hopefully if Larry or 73blazer read this they may have good some recommendations. As, anyone else that used the instructions for pre-FP9 and did not delete the 4k TS before installing g2, I assume will have this problem.

db2 error: [54010: [IBM][CLI Driver][DB2/LINUX] SQL0670N The row length of
the table exceeded a limit of "4005" bytes. (Table space "USERSPACE1".)
SQLSTATE=54010 SQLCODE=-670] in EXECUTE("ALTER TABLE g2_Schema ADD COLUMN
g_createSql VARCHAR(10000)")

I would try something like:

db2 rename table g2_schema to g2_schema_bak
db2 create table g2_schema like g2_schema_bak in <32k tsname>
db2 alter table g2_schema add primary key (g_name)
db2 insert into g2_schema select * from g2_schema_bak
db2 runstats on table xxxx.g2_schema with distribution and indexes all
db2 drop table g2_schema_bak

Yeah, DB2's default behaviour is to use the tablespace with the smallest pagesize that will fit the table at creation time. To make sure you always use the 32k tablespace, you'd have to either:

- create the database in such a way that all tablespaces are 32k in size (I'm pretty sure this can be done starting in DB2 v9, but I don't have a DB2 env in front of me right now... I'll look it up tonight)

- delete the default 4k USERSPACE1 tablespace before using the database

- Would it be that difficult to make G2 specify the tablespace in each CREATE TABLE statement, at least for DB2? The SQL syntax is simple, just add "IN <tablespace>", as in "CREATE TABLE G2_Schema IN tbspc32k".

you know more about this stuff. please change the codex page as you see fit.
thanks!

Hi.

I noticed in your SVN log that you recently started deploying use of "Truncate TABLE" but was not able to for DB2, due to the fact that DB2 has no truncate table command.

I am not sure if you are aware, of this command, but it is something we use often.

ALTER TABLE <table> not logged initially with empty table

I am now also told, although we haven't used this new set of code in production yet, that "not logged initially" is no longer required, and can be removed.
The main issue was that, with nli, errors before the next commit would change the state of the table to something less than savory. Of which you can solve by performing commits right after the alter table. With recent changes it seems that you can forego the nli altogether however.

Hope it helps.

Hi Again!

How have you been? I got a bit busy, and never did get around to filing that bug report. Before I do so, just wondering if it is still something that needs to be done?

Yesterday I decided to hide a few albums, with a "few" photos in them.

However, now any user that logs into gallery fails, due to this problem.

I did all the usual things first, I updated to latest SVN code, and cleared caches etc.

After all of that I tried disabling the image block plugin, in the hopes it would make the problem go away.

Thusly, now I have two issues I hope someone will be able to help me fix.

Firstly, I need to a way to unhide those albums, so gallery will work again.
Secondly, I am happy to help you fix the error, but I am not sure what you are doing at all.
