Getting very slow performance and high etime's or dbtime's on OVD access logs, resulting in slowness or hangs for integrated applications.
OVD 11g access.log shows high dbtime, e.g., surpassing ~5,000, for example:
[2017-10-23T18:07:02.532-02:00] [octetstring] [NOTIFICATION] [OVD-20044] [com.octetstring.accesslog] [tid: 144] [ecid: <ECID number>] conn=3,583,283 op=1 RESULT err=0 tag=0 nentries=1 etime=1,550 dbtime=1,540 mem=5,366,794,160/8,476,557,312
OVD 10g log for the LDAP search in question can show several seconds delay, e.g., etime of ~93 secs spent in Database query execution, i.e.:
End Time: 2009-02-04 20:52:33,033 conn=2 op=12 RESULT err=0 tag=0 nentries=1 etime=*93499* mem=436551072/514523136
