Home -> Community -> Mailing Lists -> Oracle-L -> ORA - 14642 : partition exchange error
Hi All,
I came across an interesting issue and thought i could get some info from the list. i did google around and metalinked, but no luck.
Environment: 9.2.0.1 - Solaris 8 / HP-11i
Actually, i was getting ORA-14642 when i was trying to exchange partition on one of my core tables. The example given below is how i can reproduce with simple example table. it shows me that if the table row length exceeds 8 characters, then it throws an error. If i reduce the column(mytext) length from 5 to 4 or anything less than 5, then everything runs fine.
I know it doesnt makes sense to create table and then alter the same. it was the old script and we were able to fix this issue by creating the right column and constraints(i mean, no "alter" command run).
I was just curious to know why it was failing and it seems like it was failing based on row length in this case. Originally it was failing on my hp(11i?) box and i tried the same on Solaris(8) and it failed there too.
any thoughts? has anyone seen this before? am i running into any known issues?
appreciate it. thanks.
