This document provides an overview of user visible changes introduced
in the B.08.30 beta releases.
Final RC (1810-8)
- eloqdb: Fixed an issue with IPv6 on HP-UX 11.31 on PA-RISC systems.
This could have the effect that local connections were not recorgnized
as local.
- eloqdb: Fixed a possible memory leak when a connection is rejected
due to insufficient user licenses.
Final RC (1810-7)
- Removed redundant diagnostic message. When opening a database more
than once a diagnostic message similar to
database(#n): open_cnt=n was output to the eloqdb message log.
This message was removed.
- The dbctl list thread output was changed to include the
operating system LWPID. The "blocked" column was removed to output the
operating system LWPID (OSID) instead.
Final RC (1810-6)
- eloqdb: Minor fixes in the eloqdb http status
- eloqdb: Fixed negative replication lag caused by timer interval
- eloqdb: Fixed bad syntax in FTS range search could trigger panic.
A specific range syntax could trigger an internal consistency check.
- eloqdb: Fixed schema upload optimization not working as expected.
When opening a database more than once the schema information is
only submitted once.
- eloqdb client library: Fixed merging of local connections.
Connections to multiple local servers could improperly use the
first database server.
- eloqdb client library: Fixed schema upload optimization not
working as expected.
- eloqdb client library: Changed library revision to B.08.30.01
RC 4
RC 3
-
eloqcore: Caching improvements and fixes using the DLG v2 protovol.
-
eloqcore: Fix unexpected behavior. Opening a file with an empty
file name will no longer succeeded on HP-UX and Linux.
This also affects previous Eloquence versions.
-
eloqdb (Linux): Add work around for glibc (nptl pthread library) defect.
Glibc Versions from 2.26 may cause the eloqdb server to hang under load.
-
eloqdb: Minor HTTP status improvements and fixes.
This is also expected to also resolve a potential issue with recent
Chrome versions to access the http status.
-
eloqdb: Add shutdown watchdog to ensure server process does
shutdown after 30 seconds even if busy. A diagnostic list
of blocked threads will be output to the message log.
-
eloqdb: Removed some potentially confusing diagnostic messages.
-
schema: Fixed a problem handling multiple index collating sequences
in a schema file. The merging identical collating sequences did not
work as expected. This also affects previous Eloquence versions.
-
image3k library: Changing the byteorder (e.g. dbcontrol mode 1000)
did not reset handling of floating point fields.
-
eloqsd: Minor HTTP status improvements and fixes.
RC 2
-
eloqcore: Fixed PRINTER IS ... ENCODING() encoding.
There was a conflict with DINTEGER.
-
eloqcore: Improved DLG caching. Caching heuristics were improved to
optimize line and vline attributes when used to
iterate on content or vcontent.
-
eloqdb: Improve handling of potential FTS index inconsistencies.
While this is no supposed to happen, handling of potential
inconsistencies was improved to allow early detection and limit its impact.
A reference to an invalid record is now logged in the server message
log and skipped ignored. Previous versions could result in partial
results, depending on the application.
-
image3k: dbcontrol mode 1020 was enhanced. Status[3] now
returns the current byte order setting. Status[2] returns the
byte order expected by the library calls.
-
image3k: dbcontrol mode 1021 returns the current character
set setting in status[2].
-
libftc: Fixed ODXFIND call to return distinct RC result count.
RC 1
Beta 8
- eloqdb: Fixed a problem resulting in the slave server aborting (#4273).
This could happen after updating to B.08.30 from a previous version and
using dbutil to restructure the database for the first time.
B.08.30 adds an internal column to the FTS definition in the database
catalog. This could be updated in the wrong order which triggers a
consistency check in the slave server to abort.
- eloqdb: Added Rate and MaxRate columns to the http thread status.
These columns describe the activation rate and max. rate of a thread.
These columns are useful to monitor the activity of a thread.
A new "rate" filter may be used to filter the output.
- eloqdb: Obtain statistics on IOWAIT time. This is the time
a specific thread had to wait for disk i/o to complete that was initiated
by another thread (as of B.08.30 this could often be an async readahead).
As B.08.30 may perform some I/O asynchroneously the I/O time is
no longer accounted to the specific thread. If a thread has to wait
for the disk I/O to complete this is now accounted as I/O time to
allow distinguishing it from disk I/O and database processing time.
This also affects the session statistics for B.08.30 to includes
three additional columns on IOWAIT.
- eloqcore: The new DLG bulk protocol is now available and enabled
by default. The new eloq.config (or .eloqrc) config option
OPTION DLGBULK may be used to modify the default:
OPTION DLGBULK {0|1|2}
0 - bulk mode is not enabled by default
1 - bulk mode is enabled by default with JDLG 2.0
2 - same as (1) but DLG SET .async is ignored (force bulk mode)
The default is 1.
If the DLG v2 protocol is used (with JDLG 2.0), enhanced diagnostics
are available. The log level G1 may be used to list failed DLG calls
along with the originating location (segment/file/line).
This is particularly useful if currently the .async option
is used to change to the more efficient and faster bulk protocol.
A noticeable difference is that in .async mode any DLG error
is ignored by default while the bulk protocol triggers a run-time error
instead.
- eloqcore: The file ENCODING functionality for writing was added.
A problem with BOM markers was corrected.
- eloqcore: New ENCODING clause for the PRINTER IS statement to allow
specifying encoding of printer output.. For example:
PRINTER IS "TEST",ENCODING("utf-8")
The following encodings are supported:
- roman8
- iso-8859-1
- iso-8859-15
- utf-8
- eloqcore: New ENCODE$() and DECODE$() function to encode
strings into or decode from utf-8 encoding.
DECODE$(ENCODE$("\u20ac"))
Characters not represented in the HP-ROMAN8/9 character set are
decoded into the \uxxxx notation.
- HP-UX installation: Fixed a problem with the symbolic links to
the OpenSSL libraries established during the installation.
OpenSSL 1.0 is used preferably when present and the symlinks are
retained on updates.
Beta 7
- eloqdb: Added support for https protocol for status monitoring.
The https protocol may be enabled in addition (or as a replacement)
to obtain status information from the database.
The following config items were added to the database server
configuration file:
- ServiceHttps
-
The service name (as defined in /etc/services)
or the port number where the server should listen
for HTTPS (secure HTTP) requests.
This requires that TLS is configured (see below).
If neither ServiceHttp nor ServiceHttps are specified,
the HTTP/HTTPS status is disabled.
- TLSCertChainFile
-
Absolute path to a file in PEM format containing
the server certificate and optionally any additional
intermediate certificates which represent the chain
up to the root certificate.
The certificates in this file must be sorted in the
verification order, starting with the server certificate.
The file may in addition contain the private key
associated with the server certificate, in which case
the TLSCertKeyFile configuration below can be omitted.
- TLSCertKeyFile
-
Absolute path to a file in PEM format containing
the private key associated with the server certificate.
If this key is contained in the TLSCertChainFile above,
configuring TLSCertKeyFile is not necessary.
Note: To enable HTTPS, a server certificate is needed for the
eloqdb host name. Web browsers require a certificate which is
issued by a known authority. Using a self-signed certificate
typically requires to configure the browsers which are used to
access the HTTPS status.
- eloqdb: The dbctl volume add command allows to add
a data volume file to the running eloqdb server process.
For example:
$ dbctl -u dba volume add /data/db/data02.vol
Added volume 3 "/data/db/data02.vol", 2 spare volumes left.
A message as below is added to the server message log:
L0: created new forward-log segment (/data/db/fwlog-2-1.log.gz)
D0: added volume [2] /data/db/data02.vol
Note: A max. of 3 data volumes may be added between server restarts.
Adding a volume file will start a new forward log generation before
the volume file is added.
Also note that the eloqdb.cfg file must be updated manually.
- eloqsd: The http and https protocol for status monitoring
may be configured separately (new ServiceHttps config item).
The https protocol may be enabled in addition (or as a replacement)
to obtain status information from the eloqsd server.
- elqocore: New ENCODING clause for the ASSIGN statement to allow
specifying encoding of sequential files. For example:
ASSIGN #1 TO "TEST";ENCODING("utf-8")
The following encodings are supported:
- roman8
- iso-8859-1
- iso-8859-15
- utf-8
- utf-16 (uft16-le, utf-16be)
Note: As of beta7 conversion is limited to reading files.
Support for writing will be added subsequently.
Beta 6
-
eloqdb client library: Fix inconsistency when used by a utility
specifying a host and/or service on the command line.
If a host or service is specified on the command line then the
EQ_DBSERVER environment variable is not used.
-
dbutil: Fix abort in dbutil when adding item access rules.
-
dbutil: The dbutil syntax DELETE ALL ITEM ACCESS was missing from the
dbutil on-line help.
-
Lock access to the IP address filter so a concurrent change
is safe.
-
Fix dbvolchange abort caused by missing initialization of the
buffer cache subsystem. This is mandatory as of B.08.30.
-
Fix issue with session and thread handling in the image3k and
ftc libraries.
-
Make sure image3k library initialization and applying
EQ3K_OPTIONS environment variable is thread safe.
-
Make sure database is actually closed when returing status 61
from the image3k dbopen call.
Beta 5
-
eloqcore: Fixed various issues with the new DLG protocol.
-
prdbutil: Add -T option to output TurboIMAGE compatble types
(dbutil -T).
-
QUERY: Support QUERY_NOLOCK environment variable to avoid database locking.
If set then QUERY will no request any database locks.
Beta 4
Beta 3
-
Correctly handle uname system call returning EOVERFLOW status on HP-UX.
-
eloqdb: Make sure FTS transactions are within 8K internal limit.
-
eloqdb: Fixed aborts caused by defects in the FTS caching to
minimize disk IO accessing FTS results.
-
eloqsd: Fixed issue with eloqsd TLS support.
