OPEN CURSORS ORACLE CODE
Have reviewed the code and it looks to me that all cursors are being closed. I am troubleshooting a C program that is erring out with an ORA-01000 error. # Problem Description and its duration: #
OPEN CURSORS ORACLE PATCH
# What version and patch set level of the database are you running? # # Platform and O/S version, including patch set or service pack level? # Could you comment on if this makes sense to you.Ĭan you easily recover from, bypass or work around the problem? = YESĭoes your system or application continue normally after the problem occurs? =Īre the standard features of the system or application still available is the
Session_cached_cursors integer I had opened up a tar on this, and just now received a response. Session cursor cache count value for 1: cursor
New 2: and lower(a.name) like '%' || lower('cursor')||'%'Ĭursor authentications value for 1: cursor Thanks for your a.name, b.value from v$statname a, v$mystat b where a.statistic# = b.statistic#Ģ and lower(a.name) like '%' || lower('&1')||'%' That shows I've 100 cursors in my "cache" ready to be opened faster then normal - but I never exceeded my 50 open cursors at a time threshold.Ĭursors are allocated in chunks (64 at a time) but the array itself that holds the cursors is allocated once.įew more questions from what i observed when i tried to simulate your exampleġ) i dont see the number of cursor allocation in chunks - why?, see i started with 9 (opened cursors cumulative) then gradually it went increased by 1.Ģ) in the below observation the number of open cursors (cumulative) have exceeded 300 but i didnt get any ora-01000 maximum open cursors exceeded' error - or is it opened cursors current i need to watch out for?ģ) when will this cursors get closed if i dont explicitly close the connection in my programĤ) i commented the close l_cursor - but still i didnt see any increase in opened cursors current. PL/SQL procedure successfully select a.name, b.value New 4: and lower(a.name) like '%' || lower('cursor')||'%'ġ0 open l_cursor for 'select * from dual xx' || i That means, "you cannot have more then 50 open at the same time - but we might cache 100 of them for you off to the select a.name, b.valueĤ and lower(a.name) like '%' || lower('&1')||'%' The only relationship they really have is - they both have cursors at the end of their show parameter _cursors It is hard to explain a relationship where none really exists. Session_cached_cursors - how many cached CLOSED cursors you can have. Open_cursor - how many concurrently opened cursors you can have.
