Informix - Problem description
| Problem IT28278 | Status: Closed |
UTF8 REPLICATION CAN CRASH WITH INADVERTENT SCHEMA DIFF BEYOND ONLY CHAR LIKE COLUMNS | |
| product: | |
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10 | |
| Problem description: | |
A crash in following stack can be reproduced when schema
differences between replicated tables exceed mere *CHAR* column
size differnces (which are allowed and may be required even for
code set conversion):
11:02:14 Assert Failed: Condition Failed (Bad allocation size
(-1912602623) for pool 'CDRD_2' (0x4aca8040)), In

Presumably (master) replicate definition should have failed up
front verifying participating schemas, but is a bit too relaxed
regarding allowed schema differences.
The problem does not occur if schemas were congruent (regarding
all non *CHAR* columns) at replicate definition time and target
table got altered with replication already in place. | |

| Local Fix: | |
Make sure only difference between schemas is in *CHAR* columns' sizes when defining a --UTF8=y replicate. | |
