Hi I have attempted to follow the post on changing the database page size from February 2013. I am using Sybase ASA 12.0.1.3942. Step 1 was to create a fresh database using dbinit - p 8k c:\sqlData\NewData\MyData12.db Step 2 was to use the dbunload command to copy the existing database to the new one with: dbunload -c "UID=DBA;PWD=sql;DBN=MyData12;DBF=c:\sqlData\MyData12.db" -ar "UID=DBA;PWD=sql;DBN=MyDataNew;DBF=c:\sqlData\NewData\MyData12.db" This results in SQL Error: Specified database file already exists. I have tried using the -ac and -an switch both giving the same error. What have I missed? I wish to change the existing database 4k page size to 8k page size keeping the same database name and file. Just as in the orignal post with the -ar option, but I can't seem to get it to work. Comment Text Removed

When you want to reload into an existing database, you cannot use option "-ar" as that creates a new database by design and replaces the old one. Instead you want to use option "-ac" instead. If you only want to change the pagesize, you could omit the step to create a new database and could then use something like (untested): in one step. Hi Volker, Didn't work, I get the same error "Specified database file already in use". Do I have to stop the database service first? The answer is yes. I have to stop the database service first. Doh!!

Ah, I see - yes, this is documented behaviour - from the DBUNLOD doc page:

Hi, Is each DB as follows? Please try the following command. dbunload -c "UID=DBA;PWD=sql;SERVER=MyData12;DBF=c:\sqlData\MyData12.db" -ac "UID=DBA;PWD=sql;SERVER=MyDataNew;DBF=c:\sqlData\NewData\MyData12.db" -xx Thanks, |
